In-Memory Applet: QueryTool

Description

In this demo, all data is kept in memory.
The data will be lost if the program is closed.
The QueryTool and the database are running
inside the internet browser.

If it does not work

On some browsers (Netscape 4.6?), the version compiled for JDK 1.2 does not work. In the Java Console (Communicator / Extras / Java Console) you will get something like:

# Verifier error org/hsqldb/jdbcConnection.getTypeMap()Ljava/util/Map

This means the class java.util.Map was not found. In JDK 1.1, this class does not exist. When compiled for 1.2, there is a reference to this class required to conform to the JDBC 2.0 interface. This class itself is never used, but the reference is required anyway. It looks like most verifiers have no problems with this, but some have.

The solution for this problem is to recompile (at least the client part) for JDK 1.1. You will need to install JDK 1.1 before you can do this, then see:

HSQL Database Engine Servlet Demo

In this demo, the DatabaseManager uses the Servlet to access the database. The QueryTool is running inside the internet browser as an Applet.

If it does not work

This demo requires a servlet engine to be running and listening to port 8080. The hsqlServlet.java servlet should be installed on the servlet engine in the /examples/servlet/ directory.

On some browsers (Netscape 4.6?), the version compiled for JDK 1.2 does not work. In the Java Console (Communicator / Extras / Java Console) you will get something like:

# Verifier error org/hsqldb/jdbcConnection.getTypeMap()Ljava/util/Map

This means the class java.util.Map was not found. In JDK 1.1, this class does not exist. When compiled for 1.2, there is a reference this class required to conform the JDBC 2.0 interface. This class itself is never used, but the reference is required anyway. It looks like most verifiers have no problem with this, but some have.

The (only) solution for this problem is to recompile (at least the client part) for JDK 1.1. You will need to install JDK 1.1 before you can do this, then see:

HSQL Database Engine Client/Server Demo

Client/server version

Currently, the applet is configured to connect to 'http://localhost', but this can be changed in the source code of this HTML page: The applet parameter 'database' is the path where the applet connects to. Close the database and stop the WebServer using the 'SHUTDOWN' command.

* * Once a session is linked with a statement, it uses the uniqe compiled * statement id for the sql statement to access the statement.

* * Changes to database structure via DDL statements, will result in all * registered CompiledStatement objects to become invalidated.

    Note: The setter methods (setShort, * setString, and so on) for setting IN parameter values * must specify types that are compatible with the defined SQL type of * the input parameter. For instance, if the IN parameter has SQL type * INTEGER, then the method setInt should be * used.

    HSQLDB-Specific Information:

    * * Starting with HSQLDB 1.7.2, jdbcPreparedStatement objects are backed by * a true compiled parameteric representation. Hence, there are now significant * performance gains to be had by using a jdbcPreparedStatement object in * preference to a jdbcStatement object, if a short-running SQL statement is * to be executed more than a small number of times.

    * * When it can be otherwise avoided, it is to be considered poor * practice to fully prepare (construct), parameterize, execute, fetch and * close a jdbcPreparedStatement object for each execution cycle. Indeed, under * HSQLDB 1.8.0, this practice is likely to be noticably less * performant for short-running statements than the equivalent process using * jdbcStatement objects, albeit far more convenient, less error prone and * certainly much less resource-intensive, especially when large binary and * character values are involved, due to the optimized parameterization * facility.

    * * Instead, when developing an application that is not totally oriented toward * the execution of ad hoc SQL, it is recommended to expend some effort toward * identifing the SQL statements that are good candidates for regular reuse and * adapting the structure of the application accordingly. Often, this is done * by recording the text of candidate SQL statements in an application resource * object (which has the nice side-benefit of isolating and hiding differences * in SQL dialects across different drivers) and caching for possible reuse the * PreparedStatement objects derived from the recorded text.

    * * Multi thread use:

    * * A PreparedStatement object is stateful and should not normally be shared * by multiple threads. If it has to be shared, the calls to set the * parameters, calls to add batch statements, the execute call and any * post-execute calls should be made within a block synchronized on the * PreparedStatement Object.

    * * JRE 1.1.x Notes:

    * * In general, JDBC 2 support requires Java 1.2 and above, and JDBC3 requires * Java 1.4 and above. In HSQLDB, support for methods introduced in different * versions of JDBC depends on the JDK version used for compiling and building * HSQLDB.

    * * Since 1.7.0, it is possible to build the product so that * all JDBC 2 methods can be called while executing under the version 1.1.x * Java Runtime EnvironmentTM. * However, in addition to requiring explicit casts to the org.hsqldb.jdbcXXX * interface implementations, some of these method calls require * int values that are defined only in the JDBC 2 or greater * version of * * ResultSet interface. For this reason, when the * product is compiled under JDK 1.1.x, these values are defined in * {@link jdbcResultSet jdbcResultSet}.

    * * In a JRE 1.1.x environment, calling JDBC 2 methods that take or return the * JDBC2-only ResultSet values can be achieved by referring * to them in parameter specifications and return value comparisons, * respectively, as follows:

    * * 

     * jdbcResultSet.FETCH_FORWARD
 * jdbcResultSet.TYPE_FORWARD_ONLY
 * jdbcResultSet.TYPE_SCROLL_INSENSITIVE
 * jdbcResultSet.CONCUR_READ_ONLY
 * // etc.
 *
    * * However, please note that code written in such a manner will not be * compatible for use with other JDBC 2 drivers, since they expect and use * ResultSet, rather than jdbcResultSet. Also * note, this feature is offered solely as a convenience to developers * who must work under JDK 1.1.x due to operating constraints, yet wish to * use some of the more advanced features available under the JDBC 2 * specification.

The JDBC API * provides a stored procedure SQL escape syntax that allows stored * procedures to be called in a standard way for all RDBMSs. This escape * syntax has one form that includes a result parameter and one that does * not. If used, the result parameter must be registered as an OUT parameter. * The other parameters can be used for input, output or both. Parameters * are referred to sequentially, by number, with the first parameter being 1. * 
     *   {?= call <procedure-name>[<arg1>,<arg2>, ...]}
 *   {call <procedure-name>[<arg1>,<arg2>, ...]}
 *
    *

    * IN parameter values are set using the set methods inherited from * {@link PreparedStatement}. The type of all OUT parameters must be * registered prior to executing the stored procedure; their values * are retrieved after execution via the get methods provided here. *

    * A CallableStatement can return one {@link ResultSet} object or * multiple ResultSet objects. Multiple * ResultSet objects are handled using operations * inherited from {@link Statement}. *

    * For maximum portability, a call's ResultSet objects and * update counts should be processed prior to getting the values of output * parameters. *

    * * *

    *

    HSQLDB-Specific Information:

    * * Since 1.7.2, the JDBC CallableStatement interface implementation has been * broken out of the jdbcPreparedStatement class into this one.

    * * With 1.7.2, some of the previously unsupported features of this interface * are now supported, such as the parameterName-based setter methods.

    * * More importantly, jdbcCallableStatement objects are now backed by a true * compiled parameteric representation. Hence, there are now significant * performance gains to be had by using a CallableStatement object instead of * a Statement object, if a short-running CALL statement is to be executed more * than a small number of times. Moreover, the recent work lays the foundation * for work in a subsequenct release to support CallableStatement OUT and * IN OUT style parameters, as well as the generation and retrieval of multiple * results in response to the execution of a CallableStatement object.

    * * For a more in-depth discussion of performance issues regarding 1.7.2 * prepared and callable statement objects, please see overview section of * {@link jdbcPreparedStatement jdbcPreparedStatment}. * *

    * * As with many DBMS, HSQLDB support for stored procedures is not provided in * a completely standard fashion.

    * * Beyond the XOpen/ODBC extended scalar functions, stored procedures are * typically supported in ways that vary greatly from one DBMS implementation * to the next. So, it is almost guaranteed that the code for a stored * procedure written under a specific DBMS product will not work without * at least some modification in the context of another vendor's product * or even across a single vendor's product lines. Moving stored procedures * from one DBMS product line to another almost invariably involves complex * porting issues and often may not be possible at all. Be warned.

    * * At present, HSQLDB stored procedures map directly onto the methods of * compiled Java classes found on the classpath of the engine at runtime. This * is done in a non-standard but fairly efficient way by issuing a class * grant (and possibly method aliases) of the form:

    * * 

     * GRANT ALL ON CLASS "package.class" TO [<user-name> | PUBLIC]
 * CREATE ALIAS <call-alias> FOR "package.class.method" -- optional
 *
    * * This has the effect of allowing the specified user(s) to access the * set of uniquely named public static methods of the specified class, * in either the role of SQL functions or stored procedures. * For example:

    * * 

     * CONNECT <admin-user> PASSWORD <admin-user-password>;
 * GRANT ALL ON CLASS "org.myorg.MyClass" TO PUBLIC;
 * CREATE ALIAS sp_my_method FOR "org.myorg.MyClass.myMethod"
 * CONNECT <any-user> PASSWORD <any-user-password>;
 * SELECT "org.myorg.MyClass.myMethod"(column_1) FROM table_1;
 * SELECT sp_my_method(column_1) FROM table_1;
 * CALL 2 + "org.myorg.MyClass.myMethod"(-5);
 * CALL 2 + sp_my_method(-5);
 *
    * * Please note the use of the term "uniquely named" above. Including * 1.7.2, no support is provided to deterministically resolve overloaded * method names, and there can be issues with inherited methods as well; * currently, it is strongly recommended that developers creating stored * procedure library classes for HSQLDB simply avoid designs such that SQL * stored procedure calls attempt to resolve to:

    * *

      *
    1. inherited public static methods *
    2. overloaded public static methods *
    * * Also, please note that OUT and IN OUT parameters * are not yet supported due to some unresolved low level support issues.

    * * Including 1.7.2, the HSQLDB stored procedure call mechanism is essentially a * thin wrap of the HSQLDB SQL function call mechanism, extended to include the * more general HSQLDB SQL expression evaluation mechanism. In addition to * stored procedure calls that resolve directly to Java method invocations, the * extention provides the ability to evaluate simple SQL expressions, possibly * containing Java method invocations, outside any INSERT, * UPDATE, DELETE or SELECT statement * context.

    * * With HSQLDB, executing a CALL statement that produces an opaque * (OTHER) or known scalar object reference has virtually the same effect as: * * 

     * CREATE TABLE DUAL (dummy VARCHAR);
 * INSERT INTO DUAL VALUES(NULL);
 * SELECT <simple-expression> FROM DUAL;
 *
    * * As a transitional measure, HSQLDB provides the ability to materialize a * general result set in response to stored procedure execution. In this case, * the stored procedure's Java method descriptor must specify a return type of * java.lang.Object for external use (although at any point in the devlopment * cycle, other, proprietary return types may accepted internally for engine * development purposes). * When HSQLDB detects that the runtime class of the resulting Object is * elligible, an automatic internal unwrapping is performed to correctly * expose the underlying result set to the client, whether local or remote.

    * * Additionally, HSQLDB automatically detects if java.sql.Connection is * the class of the first argument of any underlying Java method(s). If so, * then the engine transparently supplies the internal Connection object * corresponding to the Session executing the call, adjusting the positions * of other arguments to suite the SQL context.

    * * The features above are not intended to be permanent. Rather, the intention * is to offer more general and powerful mechanisms in a future release; * it is recommend to use them only as a temporary convenience.

    * * For instance, one might be well advised to future-proof by writing * HSQLDB-specific adapter methods that in turn call the real logic of an * underlying generalized JDBC stored procedure library.

    * * Here is a very simple example of an HSQLDB stored procedure generating a * user-defined result set: * * 

     * package mypackage;
 *
 * class MyClass {
 *
 *      public static Object mySp(Connection conn) throws SQLException {
 *          return conn.createStatement().executeQuery("select * from my_table");
 *      }
 * }
 *
    * * Here is a refinement demonstrating no more than the bare essence of the idea * behind a more portable style: * * 
     * package mypackage;
 *
 * import java.sql.ResultSet;
 * import java.sql.SQLException;
 *
 * class MyLibraryClass {
 *
 *      public static ResultSet mySp() throws SQLException {
 *          return ctx.getConnection().createStatement().executeQuery("select * from my_table");
 *      }
 * }
 *
 * //--
 *
 * package myadaptorpackage;
 *
 * import java.sql.Connection;
 * import java.sql.SQLException;
 *
 * class MyAdaptorClass {
 *
 *      public static Object mySp(Connection conn) throws SQLException {
 *          MyLibraryClass.getCtx().setConnection(conn);
 *          return MyLibraryClass.mySp();
 *      }
 * }
 *
    * * In a future release, it is intended to provided some new features * that will support writing fairly portable JDBC-based stored procedure * code:

    * *

      *
    • Support for the "jdbc:default:connection" * standard database connection url.

      * *

    • A well-defined specification of the behaviour of the HSQLDB execution * stack under stored procedure calls.

      * *

    • A well-defined, pure JDBC specification for generating multiple * results from HSQLDB stored procedures for client retrieval. *

    * This method throws an exception if there is an ambiguity, for example, * if the object is of a class implementing more than one of the * interfaces named above.

    HSQLDB-Specific Information:

    * * HSQLDB supports a subset of the ResultSetMetaData interface.

    * * The JDBC specification for ResultSetMetaData is in part very * vague. This causes potential incompatibility between interpretations of the * specification as realized in different JDBC driver implementations. As such, * deciding to what degree reporting ResultSetMetaData is accurate has been * considered very carefully. Hopefully, the design decisions made in light of * these considerations have yeilded precisely the subset of full * ResultSetMetaData support that is most commonly needed and that is most * important, while also providing, under the most common use-cases, the * fastest access with the least overhead and the best comprimise between * speed, accuracy, jar-foootprint and retention of JDBC resources.

    HSQLDB-Specific Information:

    * * HSQLDB 1.7.1 did not report this value accurately, * either always throwing or always returning false, depending * upon client property values.

    * * Starting with HSQLDB 1.7.2, this feature is better supported.

    * *

    * * However, it must be stated here that, contrary to the generic * documentation above, HSQLDB automatically numbered columns * (IDENTITY columns, in HSQLDB parlance) are not read-only.

    * * In fact, the generic documentation above seems to contradict the general * definition of what, at minimum, an auto-increment column is:

    * * Simply, an auto-increment column is one that guarantees it has a * unique value after a successful insert or update operation, even if * no value is supplied or NULL is explicitly specified by the application * or a default value expression.

    * * Further, without SQL Feature T176, Sequence generator support, the * attributes of the internal source consulted for unique values are not * defined. That is, unlike for a standard SQL SEQUENCE object or a system * with full SQL 9x or 200n support for SQL Feature T174, Identity columns, * an application must not assume and cannot determine in a standard way * that auto-increment values start at any particular point, increment by * any particular value or have any of the other attributes generally * associated with SQL SEQUENCE generators. Further still, without full * support for both feature T174 and T176, if a unique value is supplied * by an application or provided by a declared or implicit default value * expression, then whether that value is used or substituted with one * from the automatic unique value source is implementation-defined * and cannot be known in a standard way. Finally, without full support * for features T174 and T176, it is also implementation-defined and * cannot be know in a standard way whether an exception is thrown or * a unique value is automatically substituted when an application or * default value expression supplies a non-NULL, * non-unique value.

    * * Up to and including HSQLDB 1.7.2, values supplied by an application or * default value expression are used if they are indeed non-NULL unique * values, while an exception is thrown if either possible value source * for the site attempts to supply a non-NULL, non-unique value. This is * very likely to remain the behaviour of HSQLDB for its foreseable * lifetime and at the very least for the duration of the 1.7.x release * series.

    * *

    * * Regardless of the new and better support for reporting * isAutoIncrement(), it is still possible under certain conditions that * accurate reporting may be impossible. For example, if this object's * parent Connection is closed before the first call to this method or to * any other method of this class that initializes the connection-dependent * ResultSetMetaData values, then it is impossible to report accurately for * result set columns that directly represent table column values.

    * * Under such special circumstances, the driver rethrows the exception that * occured during the initialization, or a SQLException wrapping it.

    * * Those wishing to determine the auto-increment status of a table column * in isolation from ResultSetMetaData can do so by inspecting the * corresponding value of the SYSTEM_COLUMNS.IS_IDENTITY BOOLEAN column which * is also currently included (in a fashion proprietary to HSQLDB) as the * last column of the jdbcDatabaseMetaData.getColumns() result. * *

    * * * @param column the first column is 1, the second is 2, ... * @return true if so; false otherwise * @exception SQLException if a database access error occurs */ public boolean isAutoIncrement(int column) throws SQLException { checkColumn(column); return columnMetaData[--column].isAutoIncrement; } /** * * Indicates whether a column's case matters.

    * * Starting with 1.7.2, this feature is better supported.

    * *

      *
    1. Long character types and datetime types:

      * * The maximum length/precision, repectively.

      * *

    2. CHAR and VARCHAR types:

      * *

        *
      • If the result set column is a direct pass through of a table * column value, column size was declared and the connection is * to an embedded database instance, then the declared value is * returned.

        * *

      • Otherwise, the value of the system property * hsqldb.max_xxxchar_display_size or the magic value * 32766 (0x7FFE) (tested usable/accepted by most tools and * compatible with assumptions made by java.io read/write * UTF) when the system property is not defined or is not * accessible, due to security constraints.

        * *

      * * It must be noted that the latter value in no way affects the * ability of the HSQLDB JDBC driver to retrieve longer values * and serves only as the current best effort at providing a * value that maximizes usability across a wide range of tools, * given that the HSQLDB database engine does not require the * length to be declared and does not necessarily enforce it, * even if declared.

      * *

    3. Number types:

      * * The max precision, plus the length of the negation character (1), * plus (if applicable) the maximum number of characters that may * occupy the exponent character sequence. Note that some legacy tools * do not correctly handle BIGINT values of greater than 18 digits.

Within the context * of a Connection, SQL statements are executed and results * are returned.

    * * Note: By default the Connection automatically commits * changes after executing each statement. If auto commit has been * disabled, an explicit commit must be done or database changes will * not be saved.

    * * * *

    * *
    * * HSQLDB-Specific Information:

    * * To get a Connection to an HSQLDB database, the * following code may be used (updated to reflect the most recent * recommendations):

    * *

    * * When using HSQLDB, the database connection <url> must start with * 'jdbc:hsqldb:'

    * * Since 1.7.2, connection properties (<key-value-pairs>) may be appended * to the database connection <url>, using the form:

    * *

    * '<url>[;key=value]*' *

    * * Also since 1.7.2, the allowable forms of the HSQLDB database connection * <url> have been extended. However, all legacy forms continue * to work, with unchanged semantics. The extensions are as described in the * following material.

    * *

    * * Network Server Database Connections:

    * * The 1.7.2 {@link Server Server} database connection <url> has * changed to take one of the two following forms:

    * *

    *
      *
    1. 'jdbc:hsqldb:hsql://host[:port][/<alias>][<key-value-pairs>]' * *
    2. 'jdbc:hsqldb:hsqls://host[:port][/<alias>][<key-value-pairs>]' * (with TLS). *
    *

    * * The 1.7.2 {@link WebServer WebServer} database connection <url> * also changes to take one of two following forms:

    * *

    *
      *
    1. 'jdbc:hsqldb:http://host[:port][/<alias>][<key-value-pairs>]' * *
    2. 'jdbc:hsqldb:https://host[:port][/<alias>][<key-value-pairs>]' * (with TLS). *
    *

    * * In both network server database connection <url> forms, the * optional <alias> component is used to identify one of possibly * several database instances available at the indicated host and port. If the * <alias> component is omitted, then a connection is made to the * network server's default database instance.

    * * For more information on server configuration regarding mounting multiple * databases and assigning them <alias> values, please read the * Java API documentation for {@link org.hsqldb.Server Server} and related * chapters in the general documentation, especially the Advanced Users * Guide.

    * *

    * * Transient, In-Process Database Connections:

    * * The 1.7.2 100% in-memory (transient, in-process) database connection * <url> takes one of the two following forms:

    * *

    *
      *
    1. 'jdbc:hsqldb:.[<key-value-pairs>]' * (the legacy form, extended) * *
    2. 'jdbc:hsqldb:mem:<alias>[<key-value-pairs>]' * (the new form) *
    *

    * * With the 1.7.2 transient, in-process database connection <url>, * the <alias> component is the key used to look up a transient, * in-process database instance amongst the collection of all such instances * already in existence within the current class loading context in the * current JVM. If no such instance exists, one may be automatically * created and mapped to the <alias>, as governed by the * 'ifexists=true|false' connection property.

    * *

    * * Persistent, In-Process Database Connections:

    * * The 1.7.2 standalone (persistent, in-process) database connection * <url> takes one of the three following forms:

    * *

    *
      *
    1. 'jdbc:hsqldb:<path>[<key-value-pairs>]' * (the legacy form, extended) * *
    2. 'jdbc:hsqldb:file:<path>[<key-value-pairs>]' * (same semantics as the legacy form) * *
    3. 'jdbc:hsqldb:res:<path>[<key-value-pairs>]' * (new form with 'files_in_jar' semantics) *
    *

    * * For the persistent, in-process database connection <url>, * the <path> component is the path prefix common to all of * the files that compose the database.

    * * As of 1.7.2, although other files may be involved (such as transient working * files and/or TEXT table CSV data source files), the essential set that may, * at any particular point in time, compose an HSQLDB database are:

    * *

    *
      *
    • <path>.properties *
    • <path>.script *
    • <path>.log *
    • <path>.data *
    • <path>.backup *
    • <path>.lck *
    *

    * * For example: 'jdbc:hsqldb:file:test' connects to a database * composed of some subset of the files listed above, where the expansion * of <path> is 'test' prefixed with the path of the * working directory fixed at the time the JVM is started.

    * * Under Windows TM , * 'jdbc:hsqldb:file:c:\databases\test' connects to a database located * on drive 'C:' in the directory 'databases', composed * of some subset of the files:

    * * 

     * C:\
 * +--databases\
 *    +--test.properties
 *    +--test.script
 *    +--test.log
 *    +--test.data
 *    +--test.backup
 *    +--test.lck
 *
    * * Under most variations of UNIX, 'jdbc:hsqldb:file:/databases/test' * connects to a database located in the directory 'databases' directly * under root, once again composed of some subset of the files:

    * * 

     * /
 * +--databases/
 *    +--test.properties
 *    +--test.script
 *    +--test.log
 *    +--test.data
 *    +--test.backup
 *    +--test.lck
 *
    * * Some Guidelines:

    * *

      *
    1. Both relative and absolute database file paths are supported.

      * *

    2. Relative database file paths can be specified in a platform independent * manner as: '[dir1/dir2/.../dirn/]<file-name-prefix>'.

      * *

    3. Specification of absolute file paths is operating-system specific.
      * Please read your OS file system documentation.

      * *

    4. Specification of network mounts may be operating-system specific.
      * Please read your OS file system documentation.

      * *

    5. Special care may be needed w.r.t. file path specifications * containing whitespace, mixed-case, special characters and/or * reserved file names.
      * Please read your OS file system documentation.

      *

    * * Note: Versions of HSQLDB previous to 1.7.0 did not support creating * directories along the file path specified in the persistent, in-process mode * database connection <url> form, in the case that they did * not already exist. Starting with HSQLDB 1.7.0, directories will * be created if they do not already exist., but only if HSQLDB is built under * a version of the compiler greater than JDK 1.1.x.

    * * res: Connections

    * * The new 'jdbc:hsqldb:res:<path>' database connection * <url> has different semantics than the * 'jdbc:hsqldb:file:<path>' form. The semantics are similar to * those of a 'files_readonly' database, but with some additional * points to consider.

    * * Specifically, the '<path>' component of a res: type * database connection <url> is used to obtain resource URL * objects and thereby read the database files as resources on the class path. * Moreover, the URL objects must point only to resources contained * in one or more jars on the class path (must be jar protocol).

    * * This restriction is enforced to avoid the unfortunate situation in which, * because res: database instances do not create a <path>.lck file * (they are strictly files-read-only) and because the <path> * components of res: and file: database URIs are not checked * for file system equivalence, it is possible for the same database files to * be accessed concurrently by both file: and res: database * instances. That is, without this restriction, it is possible that * <path>.data and <path>.properties file content may be written * by a file: database instance without the knowlege or cooperation * of a res: database instance open on the same files, potentially * resulting in unexpected database errors, inconsistent operation * and/or data corruption.

    * * In short, a res: type database connection <url> is * designed specifically to connect to a 'files_in_jar' mode database * instance, which in turn is designed specifically to operate under * Java WebStartTM and * Java AppletTMconfigurations, * where co-locating the database files in the jars that make up the * WebStart application or Applet avoids the need for special security * configuration or code signing.

    * * Note: Since it is difficult and often nearly impossible to determine * or control at runtime from where all classes are being loaded or which class * loader is doing the loading under 'files_in_jar' semantics, the * <path> component of the res: database connection * <url> is always taken to be relative to the default package. * That is, if the <path> component does not start with '/', then * '/' is prepended when obtaining the resource URLs used to read the database * files.

    * *

    * * For more information about HSQLDB file structure, various database modes * and other attributes such as those controlled through the HSQLDB properties * files, please read the general documentation, especially the Advanced Users * Guide.

    * *

    * * JRE 1.1.x Notes:

    * * In general, JDBC 2 support requires Java 1.2 and above, and JDBC3 requires * Java 1.4 and above. In HSQLDB, support for methods introduced in different * versions of JDBC depends on the JDK version used for compiling and building * HSQLDB.

    * * Since 1.7.0, it is possible to build the product so that * all JDBC 2 methods can be called while executing under the version 1.1.x * Java Runtime EnvironmentTM. * However, in addition to this technique requiring explicit casts to the * org.hsqldb.jdbcXXX classes, some of the method calls also require * int values that are defined only in the JDBC 2 or greater * version of * * ResultSet interface. For this reason, when the * product is compiled under JDK 1.1.x, these values are defined * in {@link org.hsqldb.jdbc.jdbcResultSet jdbcResultSet}.

    * * In a JRE 1.1.x environment, calling JDBC 2 methods that take or return the * JDBC2-only ResultSet values can be achieved by referring * to them in parameter specifications and return value comparisons, * respectively, as follows:

    * * 

     * jdbcResultSet.FETCH_FORWARD
 * jdbcResultSet.TYPE_FORWARD_ONLY
 * jdbcResultSet.TYPE_SCROLL_INSENSITIVE
 * jdbcResultSet.CONCUR_READ_ONLY
 * // etc.
 *
    * * However, please note that code written to use HSQLDB JDBC 2 features under * JDK 1.1.x will not be compatible for use with other JDBC 2 drivers. Please * also note that this feature is offered solely as a convenience to developers * who must work under JDK 1.1.x due to operating constraints, yet wish to * use some of the more advanced features available under the JDBC 2 * specification.

    *

    HSQLDB-Specific Information:

    * * Up to and including 1.7.2, HSQLDB converts the JDBC SQL * grammar into the system's native SQL grammar prior to sending * it, if escape processing is set true; this method returns the * native form of the statement that the driver would send in place * of client-specified JDBC SQL grammar.

    * * Before 1.7.2, escape processing was incomplete and * also broken in terms of support for nested escapes.

    * * Starting with 1.7.2, escape processing is complete and handles nesting * to arbitrary depth, but enforces a very strict interpretation of the * syntax and does not detect or process SQL comments.

    * * In essence, the HSQLDB engine directly handles the prescribed syntax * and date / time formats specified internal to the JDBC escapes. * It also directly offers the XOpen / ODBC extended scalar * functions specified available internal to the {fn ...} JDBC escape. * As such, the driver simply removes the curly braces and JDBC escape * codes in the simplest and fastest fashion possible, by replacing them * with whitespace. * * But to avoid a great deal of complexity, certain forms of input * whitespace are currently not recognised. For instance, * the driver handles "{?= call ...}" but not "{ ?= call ...} or * "{? = call ...}"

    * * Also, comments embedded in SQL are currently not detected or * processed and thus may have unexpected effects on the output * of this method, for instance causing otherwise valid SQL to become * invalid. It is especially important to be aware of this because escape * processing is set true by default for Statement objects and is always * set true when producing a PreparedStatement from prepareStatement() * or CallableStatement from prepareCall(). Currently, it is simply * recommended to avoid submitting SQL having comments containing JDBC * escape sequence patterns and/or single or double quotation marks, * as this will avoid any potential problems. * * It is intended to implement a less strict handling of whitespace and * proper processing of SQL comments at some point in the near future, * perhaps before the final 1.7.2 release. * * In any event, 1.7.2 now correctly processes the following JDBC escape * forms to arbitrary nesting depth, but only if the exact whitespace * layout described below is used:

    * *

      *
    1. {call ...} *
    2. {?= call ...} *
    3. {fn ...} *
    4. {oj ...} *
    5. {d ...} *
    6. {t ...} *
    7. {ts ...} *

    HSQLDB-Specific Information:

    * * Up to and including 1.7.2, HSQLDB will commit the current * transaction automatically when this method is called.

    * * Additionally, HSQLDB provides a way to put a whole database in * read-only mode. This is done by manually adding the line * 'readonly=true' to the database's .properties file while the * database is offline. Upon restart, all connections will be * readonly, since the entire database will be readonly. To take * a database out of readonly mode, simply take the database * offline and remove the line 'readonly=true' from the * database's .properties file. Upon restart, the database will * be in regular (read-write) mode.

    * * When a database is put in readonly mode, its files are opened * in readonly mode, making it possible to create CD-based * readonly databases. To create a CD-based readonly database * that has CACHED tables and whose .data file is suspected of * being highly fragmented, it is recommended that the database * first be SHUTDOWN COMPACTed before copying the database * files to CD. This will reduce the space required and may * improve access times against the .data file which holds the * CACHED table data.

    * * Starting with 1.7.2, an alternate approach to opimizing the * .data file before creating a CD-based readonly database is to issue * the CHECKPOINT DEFRAG command followed by SHUTDOWN to take the * database offline in preparation to burn the database files to CD.

    A factory for connections to the physical data source that this * DataSource object represents. An alternative to the * DriverManager facility, a DataSource object * is the preferred means of getting a connection. An object that implements * the DataSource interface will typically be * registered with a naming service based on the * JavaTM Naming and Directory (JNDI) API. *

    * The DataSource interface is implemented by a driver vendor. * There are three types of implementations: *

      *
    1. Basic implementation -- produces a standard Connection * object *
    2. Connection pooling implementation -- produces a Connection * object that will automatically participate in connection pooling. This * implementation works with a middle-tier connection pooling manager. *
    3. Distributed transaction implementation -- produces a * Connection object that may be used for distributed * transactions and almost always participates in connection pooling. * This implementation works with a middle-tier * transaction manager and almost always with a connection * pooling manager. *
    *

    * A DataSource object has properties that can be modified * when necessary. For example, if the data source is moved to a different * server, the property for the server can be changed. The benefit is that * because the data source's properties can be changed, any code accessing * that data source does not need to be changed. *

    * A driver that is accessed via a DataSource object does not * register itself with the DriverManager.

    * This interface is implemented by driver vendors to let users know the * capabilities of a Database Management System (DBMS) in combination with * the driver based on JDBCTM technology * ("JDBC driver") that is used with it. Different relational DBMSs often * support different features, implement features in different ways, and use * different data types. In addition, a driver may implement a feature on * top of what the DBMS offers. Information returned by methods in this * interface applies to the capabilities of a particular driver and a * particular DBMS working together. Note that as used in this documentation, * the term "database" is used generically to refer to both the driver and DBMS. *

    * A user for this interface is commonly a tool that needs to discover how to * deal with the underlying DBMS. This is especially true for applications * that are intended to be used with more than one DBMS. For example, a tool * might use the method getTypeInfo to find out what data types * can be used in a CREATE TABLE statement. Or a user might call * the method supportsCorrelatedSubqueries to see if it is possible * to use a correlated subquery or supportsBatchUpdates to see if * it is possible to use batch updates. *

    * Some DatabaseMetaData methods return lists of information * in the form of ResultSet objects. Regular ResultSet * methods, such as getString and getInt, can be used * to retrieve the data from these ResultSet objects. If a given * form of metadata is not available, the ResultSet getter methods * throw an SQLException. *

    * Some DatabaseMetaData methods take arguments that are * String patterns. These arguments all have names such as fooPattern. * Within a pattern String, "%" means match any substring of 0 or more * characters, and "_" means match any one character. Only metadata * entries matching the search pattern are returned. If a search pattern * argument is set to null, that argument's criterion will * be dropped from the search. *

    * A method that gets information about a feature that the driver does not * support will throw an SQLException. * In the case of methods that return a ResultSet * object, either a ResultSet object (which may be empty) is * returned or an SQLException is thrown.

    * * *

    HSQLDB-Specific Information:

    * * Starting with HSQLDB 1.7.2, an option is provided to allow alternate * system table production implementations. In this distribution, there are * three implementations whose behaviour ranges from producing no system * tables at all to producing a richer and more complete body of information * about an HSQLDB database than was previously available. The information * provided through the default implementation is, unlike previous * versions, accessible to all database users, regardless of admin status. * This is now possible because the table content it produces for each * user is pre-filtered, based on the user's access rights. That is, each * system table now acts like a security-aware View.

    * * The process of installing a system table production class is transparent and * occurs dynamically at runtime during the opening sequence of a * Database instance, in the newDatabaseInformation() factory * method of the revised DatabaseInformation class, using the following * steps:

    * *

    *
      *
    1. If a class whose fully qualified name is org.hsqldb.DatabaseInformationFull * can be found and it has an accesible constructor that takes an * org.hsqldb.Database object as its single parameter, then an instance of * that class is reflectively instantiated and is used by the database * instance to produce its system tables.

      * *

    2. If 1.) fails, then the process is repeated, attempting to create an * instance of org.hsqldb.DatabaseInformationMain (which provides just the * core set of system tables required to service this class, but now does * so in a more security aware and comprehensive fashion).

      * *

    3. If 2.) fails, then an instance of org.hsqldb.DatabaseInformation is * installed (that, by default, produces no system tables, meaning that * calls to all related methods in this class will fail, throwing an * SQLException stating that a required system table is not found).

      * *

    *

    * * The process of searching for alternate implementations of database * support classes, ending with the installation of a minimal but functional * default will be refered to henceforth as graceful degradation. * This process is advantageous in that it allows developers and administrators * to easily choose packaging options, simply by adding to or deleting concerned * classes from an HSQLDB installation, without worry over providing complex * initialization properties or disrupting the core operation of the engine. * In this particular context, graceful degradation allows easy choices * regarding database metadata, spanning the range of full (design-time), * custom-written, minimal (production-time) or null * (space-constrained) system table production implementations.

    * * In the default full implementation, a number of new system tables are * provided that, although not used directly by this class, present previously * unavailable information about the database, such as about its triggers and * aliases.

    * * In order to better support graphical database exploration tools and as an * experimental intermediate step toward more fully supporting SQL9n and * SQL200n, the default installed DatabaseInformation implementation * is also capable of reporting pseudo name space information, such as * the catalog (database URI) of database objects.

    * * The catalog reporting feature is turned off by default but * can be turned on by providing the appropriate entries in the database * properties file (see the advanced topics section of the product * documentation).

    * * When the feature is turned on, catalog is reported using * the following conventions:

    * *

      *
    1. All objects are reported as having a catalog equal to the URI of the * database, which is equivalent to the catenation of the * <type> and <path> portions of the HSQLDB * internal JDBC connection URL.

      * * Examples:

      * * 

       *     "jdbc:hsqldb:file:test"      => "file:test"
 *     "jdbc:hsqldb:mem:."          => "mem:."
 *     "jdbc:hsqldb:hsql:/host/..." => URI of aliased database
 *     "jdbc:hsqldb:http:/host/..." => URI of aliased database
 *
      * * Note: No provision is made for qualifying database objects * by catalog in DML or DDL SQL. This feature is functional only with * respect to browsing the database through the DatabaseMetaData and system * table interfaces.

      * *

    * * Again, it should be well understood that this feature provide an * emulation of catalog support and is intended only * as an experimental implementation to enhance the browsing experience * when using graphical database explorers and to make a first foray * into tackling the issue of implementing true catalog support * in the future.

    * * Due the nature of the new database system table production process, fewer * assumptions can be made by this class about what information is made * available in the system tables supporting DatabaseMetaData * methods. Because of this, the SQL queries behind the ResultSet * producing methods have been cleaned up and made to adhere more strictly to * the JDBC contracts specified in relation to the method parameters.

    * * One of the remaining assumptions concerns the approximate * argument of {@link #getIndexInfo getIndexInfo()}. This parameter is still * ignored since there is not yet any process in place to internally gather * and persist table and index statistics. A primitive version of a statistics * gathering and reporting subsystem may be introduced some time in the * 1.7.x series of releases, but no hard decision has yet been made.

    * * Another assumption is that simple select queries against certain system * tables will return rows in JDBC contract order in the absence of an * "ORDER BY" clause. The reason for this is that results * come back much faster when no "ORDER BY" clause is used. * Developers wishing to extend or replace an existing system table production * class should be aware of this, either adding the contract * "ORDER BY" clause to the SQL in corresponding methods in this class, * or, better, by maintaing rows in the correct order in the underlying * system tables, prefereably by creating appropriate primary indices.

    * *

    * * JRE 1.1.x Notes:

    * * In general, JDBC 2 support requires Java 1.2 and above, and JDBC3 requires * Java 1.4 and above. In HSQLDB, support for methods introduced in different * versions of JDBC depends on the JDK version used for compiling and building * HSQLDB.

    * * Since 1.7.0, it is possible to build the product so that * all JDBC 2 methods can be called while executing under the version 1.1.x * Java Runtime EnvironmentTM. * However, some of these method calls require int values that * are defined only in the JDBC 2 or greater version of the * {@link java.sql.ResultSet ResultSet} interface. For this reason, when the * product is compiled under JDK 1.1.x, these values are defined in * {@link jdbcResultSet jdbcResultSet}.

    * * In a JRE 1.1.x environment, calling JDBC 2 methods that take or return the * JDBC2-only ResultSet values can be achieved by referring * to them in parameter specifications and return value comparisons, * respectively, as follows:

    * * 

     * jdbcResultSet.FETCH_FORWARD
 * jdbcResultSet.TYPE_FORWARD_ONLY
 * jdbcResultSet.TYPE_SCROLL_INSENSITIVE
 * jdbcResultSet.CONCUR_READ_ONLY
 * // etc
 *
    * * However, please note that code written in such a manner will not be * compatible for use with other JDBC 2 drivers, since they expect and use * ResultSet, rather than jdbcResultSet. Also * note, this feature is offered solely as a convenience to developers * who must work under JDK 1.1.x due to operating constraints, yet wish to * use some of the more advanced features available under the JDBC 2 * specification.

    HSQLDB-Specific Information:

    * * JRE 1.1.x Notes:

    * * In general, JDBC 2 support requires Java 1.2 and above, and JDBC3 requires * Java 1.4 and above. In HSQLDB, support for methods introduced in different * versions of JDBC depends on the JDK version used for compiling and building * HSQLDB.

    * * Since 1.7.0, all JDBC 2 methods can be called while executing under the * version 1.1.x * Java Runtime EnvironmentTM. * However, in addition to this technique requiring explicit casts to the * org.hsqldb.jdbcXXX classes, some of these method calls require * int values that are defined only in the JDBC 2 or greater * version of the {@link java.sql.ResultSet ResultSet} interface. For this * reason these values are defined in {@link jdbcResultSet jdbcResultSet}.

    * * In a JRE 1.1.x environment, calling JDBC 2 methods that take or return the * JDBC2-only ResultSet values can be achieved by referring * to them in parameter specifications and return value comparisons, * respectively, as follows:

    * * 

     * jdbcResultSet.FETCH_FORWARD
 * jdbcResultSet.TYPE_FORWARD_ONLY
 * jdbcResultSet.TYPE_SCROLL_INSENSITIVE
 * jdbcResultSet.CONCUR_READ_ONLY
 * //etc.
 *

    * * However, please note that code written to use HSQLDB JDBC 2 features under * JDK 1.1.x will not be compatible for use with other JDBC 2 drivers. Please * also note that this feature is offered solely as a convenience to developers * who must work under JDK 1.1.x due to operating constraints, yet wish to * use some of the more advanced features available under the JDBC 2 * specification.

    A ResultSet object maintains a cursor pointing * to its current row of data. Initially the cursor is positioned * before the first row. The next method moves the * cursor to the next row, and because it returns false * when there are no more rows in the ResultSet object, * it can be used in a while loop to iterate through * the result set. *

    * A default ResultSet object is not updatable and * has a cursor that moves forward only. Thus, you can * iterate through it only once and only from the first row to the * last row. It is possible to * produce ResultSet objects that are scrollable and/or * updatable. The following code fragment, in which con * is a valid Connection object, illustrates how to make * a result set that is scrollable and insensitive to updates by others, * and that is updatable. See ResultSet fields for other * options. * 

     *
 * Statement stmt = con.createStatement(
 *                            ResultSet.TYPE_SCROLL_INSENSITIVE,
 *                            ResultSet.CONCUR_UPDATABLE);
 * ResultSet rs = stmt.executeQuery("SELECT a, b FROM TABLE2");
 * // rs will be scrollable, will not show changes made by others,
 * // and will be updatable
 *
 *
    * The ResultSet interface provides * getter methods (getBoolean, getLong, * and so on) for retrieving column values from the current row. * Values can be retrieved using either the index number of the * column or the name of the column. In general, using the * column index will be more efficient. Columns are numbered from 1. * For maximum portability, result set columns within each row should be * read in left-to-right order, and each column should be read only once. * *

    For the getter methods, a JDBC driver attempts * to convert the underlying data to the Java type specified in the * getter method and returns a suitable Java value. The JDBC specification * has a table showing the allowable mappings from SQL types to Java types * that can be used by the ResultSet getter methods. *

    *

    Column names used as input to getter methods are case * insensitive. When a getter method is called with * a column name and several columns have the same name, * the value of the first matching column will be returned. * The column name option is * designed to be used when column names are used in the SQL * query that generated the result set. * For columns that are NOT explicitly named in the query, it * is best to use column numbers. If column names are used, there is * no way for the programmer to guarantee that they actually refer to * the intended columns. *

    * A set of updater methods were added to this interface * in the JDBC 2.0 API (JavaTM 2 SDK, * Standard Edition, version 1.2). The comments regarding parameters * to the getter methods also apply to parameters to the * updater methods. *

    * The updater methods may be used in two ways: *

      *
    1. to update a column value in the current row. In a scrollable * ResultSet object, the cursor can be moved backwards * and forwards, to an absolute position, or to a position * relative to the current row. * The following code fragment updates the NAME column * in the fifth row of the ResultSet object * rs and then uses the method updateRow * to update the data source table from which rs was * derived. * 
       *
 * rs.absolute(5); // moves the cursor to the fifth row of rs
 * rs.updateString("NAME", "AINSWORTH"); // updates the
 * // NAME column of row 5 to be AINSWORTH
 * rs.updateRow(); // updates the row in the data source
 *
 *
      *
    2. to insert column values into the insert row. An updatable * ResultSet object has a special row associated with * it that serves as a staging area for building a row to be inserted. * The following code fragment moves the cursor to the insert row, builds * a three-column row, and inserts it into rs and into * the data source table using the method insertRow. * 
       *
 * rs.moveToInsertRow(); // moves cursor to the insert row
 * rs.updateString(1, "AINSWORTH"); // updates the
 * // first column of the insert row to be AINSWORTH
 * rs.updateInt(2,35); // updates the second column to be 35
 * rs.updateBoolean(3, true); // updates the third row to true
 * rs.insertRow();
 * rs.moveToCurrentRow();
 *
 *
      *
    *

    A ResultSet object is automatically closed when the * Statement object that * generated it is closed, re-executed, or used * to retrieve the next result from a sequence of multiple results. * *

    The number, types and properties of a ResultSet * object's columns are provided by the ResulSetMetaData * object returned by the ResultSet.getMetaData method.

    * * * *

    *

    HSQLDB-Specific Information:

    * * A ResultSet object generated by HSQLDB is by default of * ResultSet.TYPE_FORWARD_ONLY (as is standard JDBC behavior) * and does not allow the use of absolute and relative positioning * methods. However, since 1.7.0, if a statement is created * with:

    * * 

     * Statement stmt = conn.createStatement(ResultSet.TYPE_SCROLL_INSENSITIVE, ResultSet.CONCUR_READ_ONLY);
 *
    * * then the ResultSet objects it produces support * using all of the absolute and relative positioning methods of JDBC2 * to set the position of the current row, for example:

    * * 

     * rs.absolute(5);
 * String fifthRowValue = rs.getString(1);
 * rs.relative(4);
 * String ninthRowValue = rs.getString(1);
 *
    * * Note: An HSQLDB ResultSet object persists, even after its * connection is closed. This is regardless of the operational mode of * the {@link Database Database} from which it came. That is, they * persist whether originating from a Server, * WebServer or in-process mode Database. *

    * * Including HSQLDB 1.7.2, there is no support for any of the methods * introduced in JDBC 2 relating to updateable result sets. These methods * include all updateXXX methods, as well as the {@link #insertRow}, * {@link #updateRow}, {@link #deleteRow}, {@link #moveToInsertRow} (and so on) * methods; invoking any such method throws an SQLException * stating that the operation is not supported. * * JRE 1.1.x Notes:

    * * In general, JDBC 2 support requires Java 1.2 and above, and JDBC 3 requires * Java 1.4 and above. In HSQLDB, support for methods introduced in different * versions of JDBC depends on the JDK version used for compiling and building * HSQLDB.

    * * Since 1.7.0, it is possible to build the product so that * all JDBC 2 methods can be called while executing under the version 1.1.x * Java Runtime EnvironmentTM. * However, some of these method calls require int values that * are defined only in the JDBC 2 or greater version of the * * ResultSet interface. For this reason, when the * product is compiled under JDK 1.1.x, these values are defined here, in this * class.

    * * In a JRE 1.1.x environment, calling JDBC 2 methods that take or return the * JDBC2-only ResultSet values can be achieved by referring * to them in parameter specifications and return value comparisons, * respectively, as follows:

    * * 

     * jdbcResultSet.FETCH_FORWARD
 * jdbcResultSet.TYPE_FORWARD_ONLY
 * jdbcResultSet.TYPE_SCROLL_INSENSITIVE
 * jdbcResultSet.CONCUR_READ_ONLY
 * // etc.
 *
    * * However, please note that code written in such a manner will not be * compatible for use with other JDBC 2 drivers, since they expect and use * ResultSet, rather than jdbcResultSet. Also * note, this feature is offered solely as a convenience to developers * who must work under JDK 1.1.x due to operating constraints, yet wish to * use some of the more advanced features available under the JDBC 2 * specification.

    * Providing a * full and robust implementation guaranteeing consistently accurate * results and behaviour depends upon introducing several new engine * features for which the internals of the product currently have no * infrastructure:

    * *

      *
    1. a unique rowid for each row in the database which lasts the life * of a row, independent of any updates made to that row
      2. *
    2. the ability to explicitly lock either the tables or the * individual rows of an updateable result, for the duration that * the result is open
      3. *
    3. the ability to choose between transactions supporting repeatable * reads, committed reads, and uncommitted reads *
    4. the ability to map an updated result row's columns back to * specific updateable objects on the database.

      * * Note: Typically, it is easy to do this mapping if all the * rows of a result consist of columns from a single table. And it * is especially easy if the result's columns are a superset of the * primary key columns of that table. The ability to * update a result consisting of any combintation of join, union, * intersect, difference and grouping operations, however, is much more * complex to implement and often impossible, especially under * grouping and non-natural joins. Also, it is not even guaranteed * that the columns of a result map back to *any* updateable object * on the database, for instance in the cases where the * result's column values are general expressions or the result * comes from a stored procedure where the data may not even come, * directly or indirectly, from updateable database objects such as * columns in table rows. *

    * * For developers working under a JDBC3 environment, * it is gently recommended to take a look at Sun's early access * * RowSet implementation, as this can be used to add * JDBC driver independent scrollablility and updateability. * However, as a driver independent implementation, it obviously cannot * guarantee to use the traditional table and/or row locking features * that many DBMS make available to ensure the success of all * valid updates against updateable results sets. As such, performing * updates through Sun's early access RowSet implementation * may not always succeed, even when it is generally expected that they * should. This is because the condition used to find the original row * on the database to update (which, for a driver independent * implementation, would have to be equality on all columns values of * the originally retrieved row) can become invalid if another * transaction modifies or deletes that row on the database at some * point between the time the row was last retrieved or refreshed in * the RowSet and the time the RowSet attempts to make its next * update to that row. Also, any driver independent implementation * of RowSet is still dependent on each driver guaranteeing that its * ResultSet objects return completely accurate * ResultSetMetaData that fulfills all of the * JDBC ResultSetMetaData contracts under all circumstances. * However, up to and including 1.7.0, HSQLDB does not make such guarantees * under all conditions. See the discussion at {@link #getMetaData}. * (boucherb@users) (version 1.7.0)

    * * Windowstm File Locking Notes:

    * * There are two major differences between Unix and Windows locking.

    * * First, Windowstm supports a share reservation programming * interface. Share reservations apply to the entire file and are specified at * the time a file is created or opened. A share reservation consists of a pair * of modes. The first is the access mode, which is how the application will * access the file: read, write, or read/write. The second is the access * that the application will deny to other applications: none, read, write, * or read/write. When the application attempts to open a file, the operating * system checks to see if there are any other open requests on the file. If so, * it first compares the application's access mode with the deny mode of the * other openers. If there is a match, then the open is denied. If not, then * the operating system compares the application's deny mode with the access * mode of the other openers. Again, if there is a match, the open is denied.

    * * Second, there is no advisory locking under Windows. Whole file * locking, byte range locking, and share reservation locking are all * mandatory.

    * * As a side note, research indicates that very few Windows programs * actually rely on byte range mandatory locking.

    * * POSIX File Locking Notes:

    * * There are three commonly found locking functions under POSIX - flock, lockf, * and fcntl.

    * * These functions, while managed by the kernel, are advisory locking mechanisms * by default. That is, the kernel does not actually stop programs from reading, * writing or deleting locked files. Instead, each program must check to see if * a lock is in place and act accordingly (be cooperative).

    * * This might be problematic when some programs are cooperative and others are * not, especially if you do not have the ability to recompile the uncooperative * code, yet it must be allowed to run.

    * * As POSIX has evolved, provisions have been made to allow locks to be enforced * at the kernel level with mandatory locking semantics. For historical reasons * [1] and for practical reasons * [2], POSIX mandatory locking is generally * implemented such that it must be configured on a file-by-file basis. When a * program attempts to lock a file with lockf or fcntl, the kernel will prevent * other programs from accessing the file if and only if the file has mandatory * locking set (note: processes which use flock never trigger a mandatory * lock).

    * * In addition, to enable mandatory locking under Linux, the target filesystem * device must be mounted with the mand option, for example:

    * * 

     * # mount -omand /dev/hdb3 /mnt/data
 *
 * # mount | grep /mnt/data
 * /dev/hdb3 on /mnt/data type ext3 (rw,mand)
 *
    * * To automate this across reboots, mand must be added to the * appropriate /etc/fstab entry.

    * * Although Linux, Solaris and HP/UX are known to support kernel-enforced * mandatory locking semantics, some POSIX systems may provide no support at all, * while others may have system-specific configuration prerequisites. Some may * even enforce manditory locking semantics by default under certain conditions * while others may silently ignore mandatory locking directives or consistently * raise exception conditions in response to such directives.

    * * Regardless of any wider scoped prerequisites, restrictions and behavioural * variations, it is generally true under POSIX that only specifically tagged * files will exhibit mandatory locks.

    * * And it is generally accepted that the way to designate a file to be governed * by mandatory locking semantics is to set its sgid (setgroupid) bit and unset * its group execute bit. This has become the commonly accepted practice * specifically because the combination is devoid of meaning in the regular * sense.

    * * As a specific illustration, if mandatory locking is required on all * pre-existing files in a certain directory, then the corresponding * chmod invocation would be:

    * * 

     * $ chmod g+s,g-x /path/to/directory/*
 *
    * *
    * * [1] * The earliest versions of Unix had no way to lock files except to create * lock files. The idea is that two or more processes would more or less * simultaneously try to create a lock file in exclusive mode, via the * O_EXCL flag of the open( ) system call. The operating system would * return success to the process that won the race, and a "file exists" * error to losing processes. One problem with this scheme is that it * relies on the winning process to remove the lock file before it exits. * If the process is running buggy software, this might not happen. * Some applications mitigate this problem by recording the process ID of * the winner into the contents of the lock file. A process that finds that * it gets a "file exists" error can then read the lock file to see if the * owning process is still running.

    * * Still, lock files can be clumsy. In the 1980s, Unix versions were * released with file locking support built into the operating system. * The System V branch of Unix offered file locking via the fcntl( ) system * call, whereas the BSD branch provided the flock( ) system call. In both * cases, when the process that creates the lock dies, the lock will be * automatically released.

    * * In a perfect world all processes would use and honour a cooperative, or * "advisory" locking scheme. However, the world isn't perfect, and there's * a lot of poorly written code out there.

    * * In trying to address this problem, the designers of System V UNIX came up * with a "mandatory" locking scheme, whereby the operating system kernel * would block attempts by a process to write to a file upon which another * process holds a "read" -or- "shared" lock, and block attempts both to * read and to write a file upon which a process holds a "write " -or- * "exclusive" lock.

    * * The System V mandatory locking scheme was intended to have as little * impact as possible on existing user code. The scheme is based on marking * individual files as candidates for mandatory locking, and using the * existing fcntl()/lockf() interface for applying locks, just as if they * were normal, advisory locks.

    * * [2] * Even with mandatory locks, conflicts can occur. If program A reads in a * file, program B locks, edits, and unlocks the file, and program A then * writes out what it originally read, this may still be less than * desirable.

    * * As well, it is generally true that nothing can override a mandatory * lock, not even root-owned processes. In this situation, the best root * can do is kill the process that has the lock upon the file.

    * * And this can be especially problematic if a file upon which a mandatory * lock exists is also available via NFS or some other remotely-accessible * filesystem, specifically because the entire fileserver process may be * forced to block until the lock is released.

    * * Indeed, these effects of mandatory locking policy are commonly encountered in * the Windowstm environment, where all locks are of the * mandatory style.

    * *

    * * Research Results:

    * * After some experimentation under JDK 1.5/6 and Linux (at least Fedora * Core 4), research results indicate that, after mounting the target file * system device using the described mand option and doing a * chmod g+s,g-x on the lock file before issuing a * FileChannel.tryLock(...), it is still possible to delete the lock * file from another process while the resulting FileLock is held, * although mandatory locking does appear to be in effect for read/write * operations.

    * * This result was actually the one anticipated, because deletion of open files * is generally possible under POSIX. In turn, this is because POSIX file * deletion simply removes the iNode entry from the file's parent directory, * while any processes with open file handles continue to have access to the * deleted file. Only when all file handles have been released does the space * occupied by the file become elligible for reuse.

    * * In other words, under both Windowstm and Linux (at lease * FC 4), it appears this class is a practically useless extension to the base. * Under Java for Windows, the act of holding a file handle open is * enough to produce a mandatory lock on the underlying file and also prevents * the file's deletion (i.e. the ultimately desired behavior occurs with or * without NIOLockFile), while under Java for Linux it appears * impossible to use NIO to produce a lock that prevents file deletion, yeilding * protection against inadvertent modification of the lock file practically * useless.

    * * To put it another way, even after the much-heralded introduction of Java * NIO, without further resorting to platform-specific JNI alternatives, we * might as well still be back in the early 80's, because we cannot guarantee, * in a cross-platform manner, conditions better than offered by the earliest * known lock file approach, even on systems that do support mandatory file * locking semantics. Instead, we must simply still trust that all software is * well written and cooperative in nature.

    * *

    * * Provides a facility for cooperative file locking across process boundaries * and isolated in-process class loader contexts.

    * * The need is obvious for inter-process cases, but it is no less essential for * in-process Java clients whose classes have been loaded by isolated class * loaders. This is because static fields--the conventional * * means for supporting in-process global discovery--become * distinct and inaccessible across Java class loader context boundaries when * the contexts do not share a common parent class loader or do not implement * normal parent class loader delegation semantics.

    * * * * The only purely in-process global discovery alternative known to the author * is to reflect upon objects found while traversing up the Java runtime thread * hierarchy. However, this method is often subject to Java security * restrictions whose collective purpose is essentially dissimilar to that of * restrictions in effect relative to cooperative file locking requirements, * making it a generally unacceptable option in this context.

    * *

    * * Here is the way this class presently operates:

    * *

      *
    1. A file with a commonly agreed-upon path is used to implement * cooperative locking semantics regarding another set of files with * commonly agreed-upon paths.

      * *

    2. In particular, a background thread periodically writes a timestamp * value, which acts as a heartbeat that indicates to others whether a * cooperative lock condition is currently held.

      * *

    3. In addition, a magic value is written so that it is possible to * distinguish with a reasonably high degree of accuracy between the * existence of a lock file and some other type of file.

      * *

    4. The generic rules used to aquire a cooperative lock condition are * as follows:

      * *

        *
      1. If a lock condition is already held by this object, do nothing and * signify that the lock attempt was successful, else...

        * *

      2. Poll the underlying file, using a configured maximum number of * retries and a configured interval between the end of a failed * poll and the beginning of the next.

        * *

      3. For each poll:

        * *

          * *
        1. Attempt to atomically create the underlying file if and only * if it does not yet exist, exit the polling loop immediately * indicating success if the attempt succeeds, else fast fail * the current poll if a security exeption is thrown in response * to the attempt, else...

          * *

        2. Test if the underlying file exists, fast failing the current * poll if it is impossible to determine (i.e. if a security * exeption is thrown).

          * *

        3. If the file does not exist, exit the polling loop immediately * indicating success.

          * * This can occur only under pre-JDK 1.2 runtimes; or when the * underlying platform does not correctly support {@link * java.io.File#createNewFile()}; or when the underlying file is * deleted within a very short time after i.), above (typically * on the order of microseconds).

          * * If the underlying platform employs a kernel-enforced mandatory * file locking blanket policy for open files (e.g. Windows * tm), then this is likely a non-issue. And if * this case makes possible a race condition with another * LockFile object (because the test for existence and * subsequent file creation is not atomic relative to all other * file system actions), it is still very unlikely that * so unfortunate a timing will occur as to allow simultaneous * lock conditions to be established. Finally, if some * non-LockFile entity deleted the file, then there are * much worse things to worry about, in particular that the files * this object is supposed to protect are in reality subject to * arbitrary external modification and deletion.

          * *

        4. Test the file's length, fast failing the current poll if the * length cannot be determined or it is not the expected * value.

          * *

        5. Open a stream to read the file's MAGIC and heartbeat * timestamp values, fast failing the current poll if the stream * cannot be opened.

          * *

        6. Test the file's MAGIC value, failing the current poll * if the value cannot be read or it is not the expected * value.

          * *

        7. Test the file's heartbeat timestamp value, fast failing the * current poll if it cannot be read or it is less than a * commonly agreed-upon value into the past (or future, to * overcome a caveat observed by a patch contributor).

          *

        *
      4. If the polling phase exits with a failure indication, then one or * more of the following cases must have been true at every poll * iteration:

        * *

          *
        • The file had the wrong length or MAGIC value (was * not an HSQLDB lock file). * *
        • The file was deleted externally after a poll's initial * test for existence and recreated at some point before * the next poll's initial test for existence. * *
        • An incompatible OS-enforced security restriction was in * effect. * *
        • An incompatible Java-enforced security restriction was * in effect. * *
        • The target file system media was effectively inaccessible. *
        • A cooperative lock condition was held by some other * LockFile. * *
        • A kernel-enforced manditory or advisory file lock was held. *

        * * In this case, signify failure indicating the last encountered * reason, else...

        * *

      5. Open the file for reading and writing, write the magic value and * an initial heartbeat timestamp, schedule a periodic heartbeat * timestamp writer task and signify success.

        *

      *
    5. The generic rules used to release a cooperative lock condition are:

      *

        *
      1. If a lock condition is not currently held, do nothing and signify * success, else...

        * *

      2. A lock condition is currently held by this object, so try to * release it.

        * * By default, releasing the lock condition consists of closing and * nullifying any objects that have a file descriptor open on the * lock file, cancelling the periodic heartbeat timestamp writer * task and deleting the lock file. If the release occurs without * raising an exception, signify success, else signify that the * release attempt might have failed.

        *

      *

    * *

    * * Additionally, {@link #doOptionalLockActions() doOptionalLockActions()} and * {@link #doOptionalReleaseActions() doOptionalReleaseActions()} are invoked * during lock and release attempts, respectively. This enables integration of * extended lock and release strategies based on subclassing. Subclass * availability is automatically detected and exposed by the factory method * {@link #newLockFile newLockFile()}.

    * * In particular, if {@link #USE_NIO_FILELOCK_PROPERTY} is true and the required * classes are available at static initialization, then newLockFile() * produces {@link org.hsqldb.NIOLockFile NIOLockFile} instances.

    * * When NIOLockFile instances are produced, then it is possible that * true kernel-enforced advisory or manditory file locking is used to protect * the underlying lock file from inadvertent modification (and possibly even * from deletion, including deletion by the system superuser). * * Otherwise, newLockFile() produces vanilla LockFile * instances, which exhibit just the elementary cooperative locking behavior on * platforms that do not, by default, implement kernel-enforced manditory * locking for open files.

    * * At this point, it must be noted that not every target platform upon which * Java can run actually provides true kernel-enforced manditory (or even * advisory) file locking. Indeed, even when a target platform does * provide such locking guarantees for local file systems, it may not be able * to do so for network file systems, or it may only be able to do so safely * (or at all) with certain restrictions. Further, external system configuration * may be a prerequisite to enable manditory locking on systems that support it * but employ advisory locking by default.

    * * In recognition of these facts, the official Java NIO package specification * explicitly states basically the same information. What is unfortunate, * however, is that no capabilities API is yet provided as part of the package. * What is even more unfortunate is that without something like a capabilities * API, it is impossible for an implementation to indicate or clients to * distiguish between simple lack of platform support and cases involving * immature Java runtimes that do not fully or correctly implement all NIO * features (and hence may throw exceptions at unexpected times or in places * where the API specification indicates none can be thrown).

    * * It is for the preceding reasons that, as of HSQLDB 1.8.0.3, * FileLock's use of Java NIO has been made a purely optional feature. * Previous to HSQLDB 1.8.0.3, if NIO was detected available, used to create a * FileLock and failed, then the enclosing cooperative lock attempt * failed also, despite the fact that a vanilla locking approach could * succeed.

    * * Polling Configuration:

    * * Although the {@link #HEARTBEAT_INTERVAL} and default polling values may * seem quite conservative, they are the result of ongoing research into * generally reasonable concerns regarding normal timing and resource * availability fluctuations experienced frequently under most, if not all * operating systems.

    * * Regardless, flexibility is almost always a good thing, so this class is * designed to allow polling interval and retry count values to be configured * at run-time.

    * * At present, this can be done at any time by setting the system properties * whose names are {@link #POLL_RETRIES_PROPERTY} and {@link * #POLL_INTERVAL_PROPERTY}.

    * * Some consideration has also been given to modifying the polling scheme so * that run-time configuration of the HEARTBEAT_INTERVAL is possible. For now, * however, this option has been rejected due to the relative complexity of * guaranteeing acceptably safe, deterministic behaviour. On the other hand, * if it can be guaranteed that certain site invariants hold (in particular, * that only one version of the hsqldb jar will ever be used to open database * instances at the site) and it is desirable or required to experiment with * a lower interval, then it is recommended for now simply to recompile the * jar using a different value in the static field assignment. Note that great * care should be taken to avoid assigning too low a value, or else it may * become possible that even very short-lived timing and resource availability * fluctuations will cause incorrect operation of this class.

    * * NIO Configuration:

    * * Starting with 1.8.0.3, NIO-enhanced file lock attempts are turned off by * default. The general reasons for this are discussed above. Anyone interested * in the reading the detailed research notes should refer to the overview of * {@link NIOLockFile}. If, after reviewing the notes and the capabilities of * the intended target platform, one should still wish to enable NIO-enhanced * file lock attempts, it can be done by setting the system property {@link * #USE_NIO_FILELOCK_PROPERTY} true at JVM startup (for example, by using a * command-line -D<property-name>=true directive). Be aware that * the system property value is read only once, in the static initializer block * for this class.

    * * Design Notes:

    * * First, it should be noted that no thread synchronization occurs in * this class. Primarily, this is because the standard entry point, * {@link #newLockFileLock(String)}, is always called from within a block * synchronized upon an HSQLDB Database instance. If this class is to be used * elsewhere and it could be accessed concurrently, then access should be * synchronized on an appropriate monitor. That said, certain members of this * class have been declared volatile to minimize possibility of inconsistent * views under concurrent read-only access.

    * * Second, to the limit of the author's present understanding, the * implementation details of this class represent a good comprimse under varying * and generally uncontrollable JVM, OS and hardware platform * limitations/capabilites, as well as under usability considerations and * external security or operating constraints that may need to be imposed.

    * * Alternate approaches that have been considered and rejected for now * include:

    * *

      *
    • Socket-based locks (with/without broadcast protocol) *
    • Pure NIO locking *
    • Simple lock file (no heartbeat or polling) *
    • JNI and native configuration alternatives *
    * * Of course, discussions involving and patches implementing improvements * or better alternatives are always welcome.

    * * As a final note and sign post for developers starting to work with * Java NIO:

    * * A separate NIOLockFile descendent exists specifically * because it was determined though experimenatation that * java.nio.channels.FileLock does not always exhibit the correct * or desired behaviour under reflective method invocation. That is, it was * discovered that under some operating system/JVM combinations, after calling * FileLock.release() via a reflective method invocation, the lock is * not released properly, deletion of the lock file is not possible even from * the owning object (this) and it is impossible for other LockFile * instances, other in-process objects or other processes to successfully obtain * a lock condition on the lock file, despite the fact that the * FileLock object reports that its lock is invalid (was released * successfully). Frustratingly, this condition appears to persist until full * exit of the process hosting the JVM in which the FileLock.tryLock() * method was reflectively invoked.

    * * To solve this, the original LockFile class was split in two and * instead of reflective method invocation, subclass instantiation is now * performed at the level of the newLockFile() factory method. * Similarly, the HSQLDB ANT build script now detects the presence or abscence * of JDK 1.4+ features such as java.nio and only attempts to build and deploy * NIOLockFile to the hsqldb.jar if such features are reported * present.

    * The database path/name is taken from the servlet engine property: *

    * If the database is deployed in the WEB-INF directory of the servlet container, * the property: *

    * * A Server object acts as a network database server and is one way of using * the client-server mode of HSQLDB Database Engine. Instances of this * class handle native HSQL protocol connections exclusively, allowing database * queries to be performed efficienly across the network. Server's direct * descendent, WebServer, handles HTTP protocol connections exclusively, * allowing HSQL protocol to be tunneled over HTTP to avoid sandbox and * firewall issues, albeit less efficiently.

    * * There are a number of ways to configure and start a Server instance.

    * * When started from the command line or programatically via the main(String[]) * method, configuration occurs in three phases, with later phases overriding * properties set by previous phases: * *

      *
    1. Upon construction, a Server object is assigned a set of default * properties.

      * *

    2. If it exists, properties are loaded from a file named * 'server.properties' in the present working directory.

      * *

    3. The command line arguments (alternatively, the String[] passed to * main()) are parsed and used to further configure the Server's * properties.

      * *

    * * From the command line, the options are as follows:

    * 

     * +----------------+-------------+----------+------------------------------+
 * |    OPTION      |    TYPE     | DEFAULT  |         DESCRIPTION          |
 * +----------------+-------------+----------+------------------------------|
 * | -?             | --          | --       | prints this message          |
 * | -address       | name|number | any      | server inet address          |
 * | -port          | number      | 9001/544 | port at which server listens |
 * | -database.i    | [type]spec  | 0=test   | path of database i           |
 * | -dbname.i      | alias       | --       | url alias for database i     |
 * | -silent        | true|false  | true     | false => display all queries |
 * | -trace         | true|false  | false    | display JDBC trace messages  |
 * | -tls           | true|false  | false    | TLS/SSL (secure) sockets     |
 * | -no_system_exit| true|false  | false    | do not issue System.exit()   |
 * | -remote_open   | true|false  | false    | can open databases remotely  |
 * +----------------+-------------+----------+------------------------------+
 *
    * * The database.i and dbname.i options need further * explanation: * *
      *
    • Multiple databases can be served by each instance of the Server. * The value of i is currently limited to the range 0..9, * allowing up to 10 different databases. Any number is this range * can be used.

      * *

    • The value assigned to database.i is interpreted using the * format '[type]spec', where the optional type component * is one of 'file:', 'res:' or 'mem:' and the * spec component is interpreted in the context of the * type component.

      * * If omitted, the type component is taken to be * 'file:'.

      * * A full description of how * '[type]spec' values are interpreted appears in the overview for * {@link org.hsqldb.jdbc.jdbcConnection jdbcConnection}.

      * *

    • The value assigned to dbname.i is taken to be the key used to * look up the desired database instance and thus corresponds to the * <alias> component of the HSQLDB HSQL protocol database * connection url: * 'jdbc:hsqldb:hsql[s]://host[port][/<alias>]'.

      * *

    • The value of database.0 is special. If dbname.0 * is not specified, then this defaults to an empty string and * a connection is made to database.0 path when * the <alias> component of an HSQLDB HSQL protocol database * connection url is omitted. If a database key/value pair is * found in the properties when the main method is called, this * pair is supersedes the database.0 setting

      * * This behaviour allows the previous * database connection url format to work with essentially unchanged * semantics.

      * *

    • When the remote_open property is true, a connection attempt * to an unopened database results in the database being opened. The URL * for connection should include the property filepath to specify the path. * 'jdbc:hsqldb:hsql[s]://host[port]/<alias>;filepath=hsqldb:file:<database path>'. * the given alias and filepath value will be associated together. The * database user and password to start this connection must be valid. * If this form of connection is used again, after the database has been * opened, the filepath property is ignored.

      * *

    • Once an alias such as "mydb" has been associated with a path, it cannot * be reassigned to a different path.

      * *

    • If a database is closed with the SHUTDOWN command, its * alias is removed. It is then possible to connect to this database again * with a different (or the same) alias.

      * *

    • If the same database is connected to via two different * aliases, and then one of the is closed with the SHUTDOWN command, the * other is also closed.

      *

    * * From the 'server.properties' file, options can be set similarly, using a * slightly different format.

    * * Here is an example 'server.properties' file: * * 

     * server.port=9001
 * server.database.0=test
 * server.dbname.0=...
 * ...
 * server.database.n=...
 * server.dbname.n=...
 * server.silent=true
 *
    * * Starting with 1.7.2, Server has been refactored to become a simple JavaBean * with non-blocking start() and stop() service methods. It is possible to * configure a Server instance through the JavaBean API as well, but this * part of the public interface is still under review and will not be finalized * or documented fully until the final 1.7.2 release.

    * * Note:

    * * The 'no_system_exit' property is of particular interest.

    * * If a Server instance is to run embedded in, say, an application server, * such as when the jdbcDataSource or HsqlServerFactory classes are used, it * is typically necessary to avoid calling System.exit() when the Server * instance shuts down.

    * * By default, 'no_system_exit' is set:

    * *

      *
    1. true when a Server is started directly from the start() * method.

      * *

    2. false when a Server is started from the main(String[]) * method. *

    * * These values are natural to their context because the first case allows * the JVM to exit by default on Server shutdown when a Server instance is * started from a command line environment, whereas the second case prevents * a typically unwanted JVM exit on Server shutdown when a Server intance * is started as part of a larger framework.

      * * WebServer has two distinct functions:

      * * The primary function is to allow client/server access to HSQLDB databases * via the HTTP protocol. This protocol is less efficient than the HSQL * protocol used by the Server class and should be used only in situations * where sandboxes or firewalls between the client and the server do not * allow the use of the HSQL protocol. One example is client/server access by * an applet running in browsers on remote hosts and accessing the database * engine on the HTTP server from which the applet originated. From version * 1.7.2, HTTP database connections are persistent and support transactions. * Similar to HSQL connections, they should be explicitly closed to free the * server resources.

      * * The secondary function of WebServer is to act as a simple general purpose * HTTP server. It is aimed to support the minimum requirements set out by * the HTTP/1.0 standard. The HEAD and GET methods can be used to query and * retreive static files from the HTTP server.

      * * Both the database server and HTTP server functions of WebServer can be * configured with the webserver.properties file. It contains entries for the * database server similar to those for the HSQL protocol Server class. In * addition, a list mapping different file endings to their mime types may be * included in this file. (fredt@users)

      * * From the command line, the options are as follows:

      *

                Class jdbcDriver

                java.lang.Object
  extended byorg.hsqldb.jdbcDriver
                All Implemented Interfaces:
                java.sql.Driver
                public class jdbcDriver
                extends java.lang.Object
                implements java.sql.Driver

                Each JDBC driver must supply a class that implements the Driver interface.

                The Java SQL framework allows for multiple database drivers.

                The DriverManager will try to load as many drivers as it can find and then for any given connection request, it will ask each driver in turn to try to connect to the target URL.

                The application developer will normally not need to call any function of the Driver directly. All required calls are made by the DriverManager.

                HSQLDB-Specific Information:

                When the HSQL Database Engine Driver class is loaded, it creates an instance of itself and register it with the DriverManager. This means that a user can load and register the HSQL Database Engine driver by calling 

                 Class.forName("org.hsqldb.jdbcDriver")
                For more information about how to connect to a HSQL Database Engine database, please see jdbcConnection.

                As of version 1.7.0 all JDBC 2 methods can be called with jdk 1.1.x. Some of these method calls require int values that are defined in JDBC 2 version of ResultSet. These values are defined in the jdbcResultSet class when it is compiled with jdk 1.1.x. When using the JDBC 2 methods that require those values as parameters or return one of those values, refer to them as follows: (The code will not be compatible with other JDBC 2 driver, which require ResultSet to be used instead of jdbcResultSet) (fredt@users)

                jdbcResultSet.FETCH_FORWARD

                jdbcDriver

                public jdbcDriver()
                Method Detail

                connect

                public java.sql.Connection connect(java.lang.String url,
                                   java.util.Properties info)
                            throws java.sql.SQLException
                Attempts to make a database connection to the given URL. The driver returns "null" if it realizes it is the wrong kind of driver to connect to the given URL. This will be common, as when the JDBC driver manager is asked to connect to a given URL it passes the URL to each loaded driver in turn.

                The driver raises a SQLException if it is the right driver to connect to the given URL, but has trouble connecting to the database.

                The java.util.Properties argument can be used to passed arbitrary string tag/value pairs as connection arguments.

                HSQLDB-Specific Information:

                For HSQL Database Engine, at least "user" and "password" properties must be included in the Properties. From version 1.7.1 two optional properties are supported:

                get_column_name if set to false, a ResultSetMetaData.getColumnName() call will return the user defined label instead of the column name. strict_md if set to true, some ResultSetMetaData methods return more strict values for compatibility reasons.

                Specified by:
                connect in interface java.sql.Driver
                Parameters:
                url - the URL of the database to which to connect
                info - a list of arbitrary string tag/value pairs as connection arguments. Normally at least a "user" and "password" property should be included.
                Returns:
                a Connection object that represents a connection to the URL
                Throws:
                java.sql.SQLException - if a database access error occurs

                getConnection

                public static java.sql.Connection getConnection(java.lang.String url,
                                                java.util.Properties info)
                                         throws java.sql.SQLException
                Throws:
                java.sql.SQLException

                acceptsURL

                public boolean acceptsURL(java.lang.String url)
                Returns true if the driver thinks that it can open a connection to the given URL. Typically drivers will return true if they understand the subprotocol specified in the URL and false if they don't.

                Specified by:
                acceptsURL in interface java.sql.Driver
                Parameters:
                url - the URL of the database
                Returns:
                true if this driver can connect to the given URL

                getPropertyInfo

                public java.sql.DriverPropertyInfo[] getPropertyInfo(java.lang.String url,
                                                     java.util.Properties info)
                Gets information about the possible properties for this driver.

                The getPropertyInfo method is intended to allow a generic GUI tool to discover what properties it should prompt a human for in order to get enough information to connect to a database. Note that depending on the values the human has supplied so far, additional values may become necessary, so it may be necessary to iterate though several calls to getPropertyInfo.

                HSQLDB-Specific Information:

                HSQLDB 1.7.2 uses the values submitted in info to set the value for each DriverPropertyInfo object returned. It does not use the default value that it would use for the property if the value is null.

                Specified by:
                getPropertyInfo in interface java.sql.Driver
                Parameters:
                url - the URL of the database to which to connect
                info - a proposed list of tag/value pairs that will be sent on connect open
                Returns:
                an array of DriverPropertyInfo objects describing possible properties. This array may be an empty array if no properties are required.

                getMajorVersion

                public int getMajorVersion()
                Gets the driver's major version number.

                Specified by:
                getMajorVersion in interface java.sql.Driver
                Returns:
                this driver's major version number

                getMinorVersion

                public int getMinorVersion()
                Gets the driver's minor version number.

                Specified by:
                getMinorVersion in interface java.sql.Driver
                Returns:
                this driver's minor version number

                jdbcCompliant

                public boolean jdbcCompliant()
                Reports whether this driver is a genuine JDBC COMPLIANTTM driver. A driver may only report true here if it passes the JDBC compliance tests; otherwise it is required to return false. JDBC compliance requires full support for the JDBC API and full support for SQL 92 Entry Level. It is expected that JDBC compliant drivers will be available for all the major commercial databases.

                HSQLDB-Specific Information:

                HSQL Database Engine currently does not yet support all required SQL 92 Entry Level functionality and thus returns false. It looks like other drivers return true but do not support all features.

                This method is not intended to encourage the development of non-JDBC compliant drivers, but is a recognition of the fact that some vendors are interested in using the JDBC API and framework for lightweight databases that do not support full database functionality, or for special databases such as document information retrieval where a SQL implementation may not be feasible.

                Specified by:
                jdbcCompliant in interface java.sql.Driver
                Returns:

                java.sql.Blob
                public class jdbcBlob
                extends java.lang.Object
                implements java.sql.Blob

                The representation (mapping) in the JavaTM programming language of an SQL BLOB value.

                Provides methods for getting the length of an SQL BLOB (Binary Large Object) value, for materializing a BLOB value on the client, and for determining the position of an octet sequence (byte pattern) within a BLOB value.

                HSQLDB-Specific Information:

                Including 1.8.x, the HSQLDB driver does not implement Blob using an SQL locator(BLOB). That is, an HSQLDB Blob object does not contain a logical pointer to SQL BLOB data; rather it directly contains a representation of the data (a byte array). As a result, an HSQLDB Blob object is itself valid beyond the duration of the transaction in which is was created, although it does not necessarily represent a corresponding value on the database.

                Currently, the interface methods for updating a BLOB value are unsupported. However, the truncate method is supported for local use.

                Since:

                Constructor Detail

                jdbcBlob

                public jdbcBlob(byte[] data)
         throws java.sql.SQLException
                Constructs a new jdbcBlob instance wrapping the given octet sequence.

                This constructor is used internally to retrieve result set values as Blob objects, yet it must be public to allow access from other packages. As such (in the interest of efficiency) this object maintains a reference to the given octet sequence rather than making a copy; special care should be taken by extenal clients never to use this constructor with a byte array object that may later be modified extenally.

                Parameters:
                data - the octet sequence representing the Blob value
                Throws:
                java.sql.SQLException - if the argument is null
                Method Detail

                length

                public long length()
            throws java.sql.SQLException
                Returns the number of bytes in the BLOB value designated by this Blob object.

                Specified by:
                length in interface java.sql.Blob
                Returns:
                length of the BLOB in bytes
                Throws:
                java.sql.SQLException - if there is an error accessing the length of the BLOB
                Since:
                JDK 1.2, HSQLDB 1.7.2

                getBytes

                public byte[] getBytes(long pos,
                       int length)
                throws java.sql.SQLException
                Retrieves all or part of the BLOB value that this Blob object represents, as an array of bytes. This byte array contains up to length consecutive bytes starting at position pos.

                HSQLDB-Specific Information:

                The official specification above is ambiguous in that it does not precisely indicate the policy to be observed when pos > this.length() - length. One policy would be to retrieve the octets from pos to this.length(). Another would be to throw an exception. HSQLDB observes the later policy.

                Specified by:
                getBytes in interface java.sql.Blob
                Parameters:
                pos - the ordinal position of the first byte in the BLOB value to be extracted; the first byte is at position 1
                length - the number of consecutive bytes to be copied
                Returns:
                a byte array containing up to length consecutive bytes from the BLOB value designated by this Blob object, starting with the byte at position pos
                Throws:
                java.sql.SQLException - if there is an error accessing the BLOB value

                An object that can be used to get information about the types and properties of the columns in a ResultSet object. The following code fragment creates the ResultSet object rs, creates the ResultSetMetaData object rsmd, and uses rsmd to find out how many columns rs has and whether the first column in rs can be used in a WHERE clause. 

                
 ResultSet rs = stmt.executeQuery("SELECT a, b, c FROM TABLE2");
 ResultSetMetaData rsmd = rs.getMetaData();
 int numberOfColumns = rsmd.getColumnCount();
 boolean b = rsmd.isSearchable(1);

                HSQLDB-Specific Information:

                HSQLDB supports a subset of the ResultSetMetaData interface.

                The JDBC specification for ResultSetMetaData is in part very vague. This causes potential incompatibility between interpretations of the specification as realized in different JDBC driver implementations. As such, deciding to what degree reporting ResultSetMetaData is accurate has been considered very carefully. Hopefully, the design decisions made in light of these considerations have yeilded precisely the subset of full ResultSetMetaData support that is most commonly needed and that is most important, while also providing, under the most common use-cases, the fastest access with the least overhead and the best comprimise between speed, accuracy, jar-foootprint and retention of JDBC resources.

                Indicates whether the designated column is automatically numbered, thus read-only.

                HSQLDB-Specific Information:

                HSQLDB 1.7.1 did not report this value accurately, either always throwing or always returning false, depending upon client property values.

                Starting with HSQLDB 1.7.2, this feature is better supported.

                However, it must be stated here that, contrary to the generic documentation above, HSQLDB automatically numbered columns (IDENTITY columns, in HSQLDB parlance) are not read-only.

                In fact, the generic documentation above seems to contradict the general definition of what, at minimum, an auto-increment column is:

                Simply, an auto-increment column is one that guarantees it has a unique value after a successful insert or update operation, even if no value is supplied or NULL is explicitly specified by the application or a default value expression.

                Further, without SQL Feature T176, Sequence generator support, the attributes of the internal source consulted for unique values are not defined. That is, unlike for a standard SQL SEQUENCE object or a system with full SQL 9x or 200n support for SQL Feature T174, Identity columns, an application must not assume and cannot determine in a standard way that auto-increment values start at any particular point, increment by any particular value or have any of the other attributes generally associated with SQL SEQUENCE generators. Further still, without full support for both feature T174 and T176, if a unique value is supplied by an application or provided by a declared or implicit default value expression, then whether that value is used or substituted with one from the automatic unique value source is implementation-defined and cannot be known in a standard way. Finally, without full support for features T174 and T176, it is also implementation-defined and cannot be know in a standard way whether an exception is thrown or a unique value is automatically substituted when an application or default value expression supplies a non-NULL, non-unique value.

                Up to and including HSQLDB 1.7.2, values supplied by an application or default value expression are used if they are indeed non-NULL unique values, while an exception is thrown if either possible value source for the site attempts to supply a non-NULL, non-unique value. This is very likely to remain the behaviour of HSQLDB for its foreseable lifetime and at the very least for the duration of the 1.7.x release series.

                Regardless of the new and better support for reporting isAutoIncrement(), it is still possible under certain conditions that accurate reporting may be impossible. For example, if this object's parent Connection is closed before the first call to this method or to any other method of this class that initializes the connection-dependent ResultSetMetaData values, then it is impossible to report accurately for result set columns that directly represent table column values.

                Under such special circumstances, the driver rethrows the exception that occured during the initialization, or a SQLException wrapping it.

                Those wishing to determine the auto-increment status of a table column in isolation from ResultSetMetaData can do so by inspecting the corresponding value of the SYSTEM_COLUMNS.IS_IDENTITY BOOLEAN column which is also currently included (in a fashion proprietary to HSQLDB) as the last column of the jdbcDatabaseMetaData.getColumns() result.

                isAutoIncrement in interface java.sql.ResultSetMetaData

                Indicates whether a column's case matters.

                HSQLDB-Specific Information:

                HSQLDB 1.7.1 did not report this value accurately.

                Starting with 1.7.2, this feature is better supported.

                This method returns true for any column whose data type is a character type, with the exception of VARCHAR_IGNORECASE for which it returns false. It also returns false for any column whose data type is a not a character data type.

                Returns:
                true if so; false otherwise
                Throws:
                java.sql.SQLException - if a database access error occurs

                public boolean isSearchable(int column)
                     throws java.sql.SQLException
                Indicates whether the designated column can be used in a where clause.

                HSQLDB-Specific Information:

                HSQLDB 1.7.1 did not report this value accurately.

                Starting with 1.7.2, this feature is better supported.

                If the data type of the column is definitely known to be searchable in any way under HSQLDB, then true is returned, else false. That is, if the type is reported in DatabaseMetaData.getTypeInfo() as having DatabaseMetaData.typePredNone or is not reported, then false is returned, else true.

                Specified by:
                isSearchable in interface java.sql.ResultSetMetaData
                Parameters:
                column - the first column is 1, the second is 2, ...
                Returns:
                true if so; false otherwise
                Throws:
                java.sql.SQLException - if a database access error occurs

                isCurrency

                public boolean isCurrency(int column)
                   throws java.sql.SQLException
                Indicates whether the designated column is a cash value.

                HSQLDB-Specific Information:

                Up to and including HSQLDB 1.7.2, this method always returns false.

                This is because true fixed (precision,scale) data types are not yet supported. That is, DECIMAL and NUMERIC types are implemented as a thin wrap of java.math.BigDecimal, which cannot, without additional, as yet unimplemented constraint enforcement code, be said to be a fixed (precision,scale) types.

                Specified by:
                isCurrency in interface java.sql.ResultSetMetaData
                Parameters:
                column - the first column is 1, the second is 2, ...
                Returns:
                true if so; false otherwise
                Throws:
                java.sql.SQLException - if a database access error occurs

                isNullable

                public int isNullable(int column)
               throws java.sql.SQLException
                Indicates the nullability of values in the designated column.

                HSQLDB-Specific Information:

                Up to 1.7.1, HSQLDB did not report this value accurately.

                Starting with 1.7.2, this feature is better supported.

                columnNullableUnknown is always returned for result set columns that do not directly represent table column values (i.e. are calculated), while the corresponding value in SYSTEM_COLUMNS.NULLABLE is returned for result set columns that do directly represent table column values.

                Those wishing to determine the nullable status of a table column in isolation from ResultSetMetaData and in a DBMS-independent fashion can do so by calling DatabaseMetaData.getColumns() with the appropriate filter values and inspecting the result at the position described in the API documentation.

                Specified by:
                isNullable in interface java.sql.ResultSetMetaData
                Parameters:
                column - the first column is 1, the second is 2, ...
                Returns:
                the nullability status of the given column; one of columnNoNulls, columnNullable or columnNullableUnknown
                Throws:
                java.sql.SQLException - if a database access error occurs

                isSigned

                public boolean isSigned(int column)
                 throws java.sql.SQLException
                Indicates whether values in the designated column are signed numbers.

                HSQLDB-Specific Information:

                HSQLDB 1.7.1 introduced support for this feature and 1.7.2 reports identical values (although using a slightly different implementation).

                Specified by:
                isSigned in interface java.sql.ResultSetMetaData
                Parameters:
                column - the first column is 1, the second is 2, ...
                Returns:
                true if so; false otherwise
                Throws:
                java.sql.SQLException - if a database access error occurs

                getColumnDisplaySize

                public int getColumnDisplaySize(int column)
                         throws java.sql.SQLException
                Indicates the designated column's normal maximum width in characters.

                HSQLDB-Specific Information:

                Up to and including HSQLDB 1.7.1, this method always returned 0, which was intended to convey unknown display size. Unfortunately, this value is not universally handled by all clients and in the worst case can cause some applications to crash.

                Starting with 1.7.2, this feature is better supported.

                The current calculation follows these rules:

                1. Long character types and datetime types:

                  The maximum length/precision, repectively.

                2. CHAR and VARCHAR types:

                  • If the result set column is a direct pass through of a table column value, column size was declared and the connection is to an embedded database instance, then the declared value is returned.

                  • Otherwise, the value of the system property hsqldb.max_xxxchar_display_size or the magic value 32766 (0x7FFE) (tested usable/accepted by most tools and compatible with assumptions made by java.io read/write UTF) when the system property is not defined or is not accessible, due to security constraints.

                  It must be noted that the latter value in no way affects the ability of the HSQLDB JDBC driver to retrieve longer values and serves only as the current best effort at providing a value that maximizes usability across a wide range of tools, given that the HSQLDB database engine does not require the length to be declared and does not necessarily enforce it, even if declared.

                3. Number types:

                  The max precision, plus the length of the negation character (1), plus (if applicable) the maximum number of characters that may occupy the exponent character sequence. Note that some legacy tools do not correctly handle BIGINT values of greater than 18 digits.

                4. BOOLEAN (BIT) type:

                  The length of the character sequence "false" (5), the longer of the two boolean value String representations.

                5. Remaining types:

                  The maximum length/precision, respectively, as reported by DatabaseMetaData.getTypeInfo(), when applicable. If the maximum display size is unknown, unknowable or inapplicable, then zero is returned.

                Specified by:
                getColumnDisplaySize in interface java.sql.ResultSetMetaData
                Parameters:
                column - the first column is 1, the second is 2, ...
                Returns:
                the normal maximum number of characters allowed as the width of the designated column
                Throws:
                java.sql.SQLException - if a database access error occurs

                getColumnLabel

                public java.lang.String getColumnLabel(int column)
                                throws java.sql.SQLException
                Gets the designated column's suggested title for use in printouts and displays.

                HSQLDB-Specific Information:

                In HSQLDB a ResultSet column label is determined in the following order of precedence:

                1. The label (alias) specified in the generating query.
                2. The name of the underlying column, if no label is specified.
                  This also applies to aggregate functions.
                3. An empty String.

                Specified by:
                getColumnLabel in interface java.sql.ResultSetMetaData
                Parameters:
                column - the first column is 1, the second is 2, ...
                Returns:
                the suggested column title
                Throws:
                java.sql.SQLException - if a database access error occurs

                getColumnName

                public java.lang.String getColumnName(int column)
                               throws java.sql.SQLException
                Get the designated column's name.

                HSQLDB-Specific Information:

                In HSQLDB a ResultSet column name is determined in the following order of prcedence:

                1. The name of the underlying columnm, if the ResultSet column represents a column in a table.
                2. The label or alias specified in the generating query.
                3. An empty String.

                If the jdbc.get_column_name property of the database has been set to false, this method returns the same value as getColumnLabel(int).

                Specified by:
                getColumnName in interface java.sql.ResultSetMetaData
                Parameters:
                column - the first column is 1, the second is 2, ...
                Returns:
                column name
                Throws:
                java.sql.SQLException - if a database access error occurs

                getSchemaName

                public java.lang.String getSchemaName(int column)
                               throws java.sql.SQLException
                Get the designated column's table's schema.

                HSQLDB-Specific Information:

                Up to 1.7.1, HSQLDB did not support the notion of schemas at all, including schema names in result set metadata; this method always returned "".

                Staring with 1.7.2, schema name reporting is supported only as an optional, experimental feature that is disabled by default. Enabling this feature requires setting the database property "hsqldb.schemas=true".

                Specifically, when this feature is enabled under 1.7.2, only very limited support is provided by the engine for executing SQL containing schema-qualified database object identifiers. That is, when this feature is enabled under 1.7.2, it is not yet possible in most cases to use what would otherwise be the correct, canonical SQL calculated from ResultSetMetaData.

                Regardless, reporting is done only in system table content and is not yet carried over to ResultSetMetaData.

                column - the first column is 1, the second is 2, ...

                public int getPrecision(int column)
                 throws java.sql.SQLException
                Get the designated column's number of decimal digits.

                HSQLDB-Specific Information:

                Starting with 1.8.0, HSQLDB reports the the declared length or precision specifiers for table columns (if they are defined, which up to 1.7.2 is not a requirement in DDL), as these values may or may not be enforced, depending on the value of the database property: 

                 sql.enforce_strict_size
                Because the property may change from one instantiation of a Database to the next and because, when set true, is not applied to existing values in table columns (only to new values introduced by following inserts and updates), the length and/or precision specifiers for table columns still do not neccessarily accurately reflect true constraints upon the contents of the columns. This situation may or may not change in a future release.

                Specified by:
                getPrecision in interface java.sql.ResultSetMetaData

                getScale

                public int getScale(int column)
             throws java.sql.SQLException
                Gets the designated column's number of digits to right of the decimal point.

                HSQLDB-Specific Information:

                Starting with 1.8.0, HSQLDB reports the declared scale for table columns depending on the value of the database property: 

                 sql.enforce_strict_size

                Gets the designated column's table's catalog name.

                HSQLDB-Specific Information:

                Up to and including 1.7.1, HSQLDB did not support the notion of catalog and this method always returned "".

                Starting with 1.7.2, HSQLDB supports catalog reporting only as an optional, experimental feature that is disabled by default. Enabling this feature requires setting the database property "hsqldb.catalogs=true". When enabled, the catalog name for table columns is reported as the name by which the hosting Database knows itself.

                HSQLDB does not yet support any use of catalog qualification in DLL or DML. This fact is accurately indicated in the corresponding DatabaseMetaData.supportsXXX() method return values.

                Regardless, reporting is done only in system table content and is not yet carried over to ResultSetMetaData.

                Indicates whether the designated column is definitely not writable.

                HSQLDB-Specific Information:

                Up to and including 1.7.1, HSQLDB did not report this value accurately.

                Starting with HSQLDB 1.7.2, this feature is better supported.

                For result set columns that do not directly represent table column values (i.e. are calculated), true is reported. Otherwise, the read only status of the table and the database are used in the calculation, but not the read-only status of the session.

                Indicates whether it is possible for a write on the designated column to succeed.

                HSQLDB-Specific Information:

                Up to and including 1.7.1, HSQLDB did not report this value accurately.

                Starting with HSQLDB 1.7.2, this feature is better supported.

                In essense, the negation of isReadOnly() is reported.

                HSQLDB-Specific Information:

                HSQLDB 1.7.1 did not report this value accurately.

                Starting with HSQLDB 1.7.2, this method always returns false. The reason for this is that it is generally either very complex or simply impossible to calculate deterministically true for table columns under all concievable conditions. The value is of dubious usefulness, except perhaps if there were support for updateable result sets using "SELECT ... FOR UPDATE" style locking. However, this is not anticipated to occur any time in the 1.7.x release series.

                                    throws java.sql.SQLException
                Returns the fully-qualified name of the Java class whose instances are manufactured if the method ResultSet.getObject is called to retrieve a value from the column. ResultSet.getObject may return a subclass of the class returned by this method.

                HSQLDB-Specific Information:

                HSQLDB 1.7.1 did not support this feature; calling this method always caused an SQLException to be thrown, stating that the function was not supported.

                Specified by:
                getColumnClassName in interface java.sql.ResultSetMetaData
                Parameters:
                column - the first column is 1, the second is 2, ...
                Returns:
                the fully-qualified name of the class in the Java programming language that would be used by the method ResultSet.getObject to retrieve the value in the specified column. This is the class name used for custom mapping.
                Throws:
                java.sql.SQLException - if a database access error occurs

                Class jdbcStatement

                java.lang.Object
  extended byorg.hsqldb.jdbc.jdbcStatement
                All Implemented Interfaces:
                java.sql.Statement
                Direct Known Subclasses:
                jdbcPreparedStatement
                public class jdbcStatement
                extends java.lang.Object
                implements java.sql.Statement

                The object used for executing a static SQL statement and returning the results it produces.

                By default, only one ResultSet object per Statement object can be open at the same time. Therefore, if the reading of one ResultSet object is interleaved with the reading of another, each must have been generated by different Statement objects. All execution methods in the Statement interface implicitly close a statment's current ResultSet object if an open one exists.

                HSQLDB-Specific Information:

                JRE 1.1.x Notes:

                In general, JDBC 2 support requires Java 1.2 and above, and JDBC3 requires Java 1.4 and above. In HSQLDB, support for methods introduced in different versions of JDBC depends on the JDK version used for compiling and building HSQLDB.

                Since 1.7.0, all JDBC 2 methods can be called while executing under the version 1.1.x Java Runtime EnvironmentTM. However, in addition to this technique requiring explicit casts to the org.hsqldb.jdbcXXX classes, some of these method calls require int values that are defined only in the JDBC 2 or greater version of the ResultSet interface. For this reason these values are defined in jdbcResultSet.

                In a JRE 1.1.x environment, calling JDBC 2 methods that take or return the JDBC2-only ResultSet values can be achieved by referring to them in parameter specifications and return value comparisons, respectively, as follows: 

                 jdbcResultSet.FETCH_FORWARD
 jdbcResultSet.TYPE_FORWARD_ONLY
 jdbcResultSet.TYPE_SCROLL_INSENSITIVE
 jdbcResultSet.CONCUR_READ_ONLY
 //etc.

                However, please note that code written to use HSQLDB JDBC 2 features under JDK 1.1.x will not be compatible for use with other JDBC 2 drivers. Please also note that this feature is offered solely as a convenience to developers who must work under JDK 1.1.x due to operating constraints, yet wish to use some of the more advanced features available under the JDBC 2 specification.

                Method Detail

                executeQuery

                public java.sql.ResultSet executeQuery(java.lang.String sql)
                                throws java.sql.SQLException
                Executes the given SQL statement, which returns a single ResultSet object.

                HSQLDB-Specific Information:

                This method should not be used for statements other than SELECT queries.

                Including 1.7.2, HSQLDB does not throw an exception when the statement is a DDL statement or an UPDATE or DELETE statement. This will certainly change in future version.

                Specified by:
                executeQuery in interface java.sql.Statement
                Parameters:
                sql - an SQL statement to be sent to the database, typically a static SQL SELECT statement
                Returns:
                a ResultSet object that contains the data produced by the given query; never null
                Throws:
                java.sql.SQLException - if a database access error occurs or the given SQL statement produces anything other than a single ResultSet object

                executeUpdate

                public int executeUpdate(java.lang.String sql)
                  throws java.sql.SQLException
                Executes the given SQL statement, which may be an INSERT, UPDATE, or DELETE statement or an SQL statement that returns nothing, such as an SQL DDL statement.

                Specified by:
                executeUpdate in interface java.sql.Statement
                Parameters:
                sql - an SQL INSERT, UPDATE or DELETE statement or an SQL statement that returns nothing
                Returns:
                either the row count for INSERT, UPDATE or DELETE statements, or 0 for SQL statements that return nothing
                Throws:
                java.sql.SQLException - if a database access error occurs or the given SQL statement produces a ResultSet object

                close

                public void close()
           throws java.sql.SQLException
                Releases this Statement object's database and JDBC resources immediately instead of waiting for this to happen when it is automatically closed. It is generally good practice to release resources as soon as you are finished with them to avoid tying up database resources.

                Calling the method close on a Statement object that is already closed has no effect.

                Note: A Statement object is automatically closed when it is garbage collected. When a Statement object is closed, its current ResultSet object, if one exists, is also closed.

                Specified by:
                close in interface java.sql.Statement
                Throws:
                java.sql.SQLException - if a database access error occurs

                getMaxFieldSize

                public int getMaxFieldSize()
                    throws java.sql.SQLException
                Retrieves the maximum number of bytes that can be returned for character and binary column values in a ResultSet object produced by this Statement object. This limit applies only to BINARY, VARBINARY, LONGVARBINARY, CHAR, VARCHAR, and LONGVARCHAR columns. If the limit is exceeded, the excess data is silently discarded.

                HSQLDB-Specific Information:

                Including 1.7.2, HSQLDB always returns zero, meaning there is no limit.

                Specified by:
                getMaxFieldSize in interface java.sql.Statement
                Returns:
                the current column size limit for columns storing character and binary values; zero means there is no limit
                Throws:
                java.sql.SQLException - if a database access error occurs
                See Also:
                setMaxFieldSize(int)

                setMaxFieldSize

                public void setMaxFieldSize(int max)
                     throws java.sql.SQLException
                Sets the limit for the maximum number of bytes in a ResultSet column storing character or binary values to the given number of bytes. This limit applies only to BINARY, VARBINARY, LONGVARBINARY, CHAR, VARCHAR, and LONGVARCHAR fields. If the limit is exceeded, the excess data is silently discarded. For maximum portability, use values greater than 256.

                HSQLDB-Specific Information:

                Including 1.7.2, calls to this method are simply ignored; HSQLDB always stores the full number of bytes when dealing with any of the field types mentioned above. These types all have an absolute maximum element upper bound determined by the Java array index limit java.lang.Integer.MAX_VALUE. For XXXBINARY types, this translates to Integer.MAX_VALUE bytes. For XXXCHAR types, this translates to 2 * Integer.MAX_VALUE bytes (2 bytes / character)

                Specified by:
                setMaxFieldSize in interface java.sql.Statement
                Parameters:
                max - the new column size limit in bytes; zero means there is no limit
                Throws:
                java.sql.SQLException - if a database access error occurs or the condition max >= 0 is not satisfied
                See Also:
                getMaxFieldSize()

                getMaxRows

                public int getMaxRows()
               throws java.sql.SQLException
                Retrieves the maximum number of rows that a ResultSet object produced by this Statement object can contain. If this limit is exceeded, the excess rows are silently dropped.

                Specified by:
                getMaxRows in interface java.sql.Statement
                Returns:
                the current maximum number of rows for a ResultSet object produced by this Statement object; zero means there is no limit
                Throws:
                java.sql.SQLException - if a database access error occurs
                See Also:
                setMaxRows(int)

                setMaxRows

                public void setMaxRows(int max)
                throws java.sql.SQLException
                Sets the limit for the maximum number of rows that any ResultSet object can contain to the given number. If the limit is exceeded, the excess rows are silently dropped.

                Specified by:
                setMaxRows in interface java.sql.Statement
                Parameters:
                max - the new max rows limit; zero means there is no limit
                Throws:
                java.sql.SQLException - if a database access error occurs or the condition max >= 0 is not satisfied
                See Also:
                getMaxRows()

                setEscapeProcessing

                public void setEscapeProcessing(boolean enable)
                         throws java.sql.SQLException
                Sets escape processing on or off. If escape scanning is on (the default), the driver will do escape substitution before sending the SQL statement to the database. Note: Since prepared statements have usually been parsed prior to making this call, disabling escape processing for PreparedStatements objects will have no effect.

                Specified by:
                setEscapeProcessing in interface java.sql.Statement
                Parameters:
                enable - true to enable escape processing; false to disable it
                Throws:

                getQueryTimeout

                public int getQueryTimeout()
                    throws java.sql.SQLException
                Retrieves the number of seconds the driver will wait for a Statement object to execute. If the limit is exceeded, an SQLException is thrown.

                HSQLDB-Specific Information:

                Including 1.7.2, HSQLDB always returns zero, meaning there is no limit.

                Specified by:
                getQueryTimeout in interface java.sql.Statement
                Returns:
                the current query timeout limit in seconds; zero means there is no limit
                Throws:
                java.sql.SQLException - if a database access error occurs

                public void setQueryTimeout(int seconds)
                     throws java.sql.SQLException
                Sets the number of seconds the driver will wait for a Statement object to execute to the given number of seconds. If the limit is exceeded, an SQLException is thrown.

                HSQLDB-Specific Information:

                Including 1.7.2, calls to this method are ignored; HSQLDB waits an unlimited amount of time for statement execution requests to return.

                Specified by:
                setQueryTimeout in interface java.sql.Statement
                Parameters:
                seconds - the new query timeout limit in seconds; zero means there is no limit
                Throws:
                java.sql.SQLException - if a database access error occurs or the condition seconds >= 0 is not satisfied

                cancel

                public void cancel()
            throws java.sql.SQLException
                Cancels this Statement object if both the DBMS and driver support aborting an SQL statement. This method can be used by one thread to cancel a statement that is being executed by another thread.

                HSQLDB-Specific Information:

                Including 1.7.2, HSQLDB does not support aborting a SQL statement; calls to this method are ignored.

                Specified by:
                cancel in interface java.sql.Statement
                Throws:

                getWarnings

                public java.sql.SQLWarning getWarnings()
                                throws java.sql.SQLException
                Retrieves the first warning reported by calls on this Statement object. Subsequent Statement object warnings will be chained to this SQLWarning object.

                The warning chain is automatically cleared each time a statement is (re)executed. This method may not be called on a closed Statement object; doing so will cause an SQLException to be thrown.

                Note: If you are processing a ResultSet object, any warnings associated with reads on that ResultSet object will be chained on it rather than on the Statement object that produced it.

                HSQLDB-Specific Information:

                Including 1.7.2, HSQLDB never produces Statement warnings; this method always returns null.

                Specified by:
                getWarnings in interface java.sql.Statement
                Returns:
                the first SQLWarning object or null if there are no warnings
                Throws:
                java.sql.SQLException - if a database access error occurs or this method is called on a closed statement

                clearWarnings

                public void clearWarnings()
                   throws java.sql.SQLException
                Clears all the warnings reported on this Statement object. After a call to this method, the method getWarnings will return null until a new warning is reported for this Statement object.

                HSQLDB-Specific Information:

                Including HSQLDB 1.7.2, SQLWarning objects are never produced for Statement Objects; calls to this method are ignored.

                Specified by:
                clearWarnings in interface java.sql.Statement
                Throws:

                setCursorName

                public void setCursorName(java.lang.String name)
                   throws java.sql.SQLException
                Sets the SQL cursor name to the given String, which will be used by subsequent Statement object execute methods. This name can then be used in SQL positioned update or delete statements to identify the current row in the ResultSet object generated by this statement. If the database does not support positioned update/delete, this method is a noop. To insure that a cursor has the proper isolation level to support updates, the cursor's SELECT statement should have the form SELECT FOR UPDATE. If FOR UPDATE is not present, positioned updates may fail.

                Note: By definition, the execution of positioned updates and deletes must be done by a different Statement object than the one that generated the ResultSet object being used for positioning. Also, cursor names must be unique within a connection.

                HSQLDB-Specific Information:

                Including 1.7.2, HSQLDB does not support named cursors, updateable results or table locking via SELECT FOR UPDATE; calls to this method are ignored.

                Specified by:
                setCursorName in interface java.sql.Statement
                Parameters:
                name - the new cursor name, which must be unique within a connection

                java.sql.SQLException - if a database access error occurs

                execute

                public boolean execute(java.lang.String sql)
                throws java.sql.SQLException
                Executes the given SQL statement, which may return multiple results. In some (uncommon) situations, a single SQL statement may return multiple result sets and/or update counts. Normally you can ignore this unless you are (1) executing a stored procedure that you know may return multiple results or (2) you are dynamically executing an unknown SQL string.

                The execute method executes an SQL statement and indicates the form of the first result. You must then use the methods getResultSet or getUpdateCount to retrieve the result, and getMoreResults to move to any subsequent result(s).

                Specified by:
                execute in interface java.sql.Statement
                Parameters:
                sql - any SQL statement
                Returns:
                true if the first result is a ResultSet object; false if it is an update count or there are no results

                Retrieves the current result as a ResultSet object. This method should be called only once per result.

                HSQLDB-Specific Information:

                Without an interceding call to executeXXX, each invocation of this method will produce a new, initialized ResultSet instance referring to the current result, if any.

                Specified by:

                   throws java.sql.SQLException
                Retrieves the current result as an update count; if the result is a ResultSet object or there are no more results, -1 is returned. This method should be called only once per result.

                Specified by:
                getUpdateCount in interface java.sql.Statement
                Returns:

                Moves to this Statement object's next result, returns true if it is a ResultSet object, and implicitly closes any current ResultSet object(s) obtained with the method getResultSet.

                There are no more results when the following is true: 

                    (!getMoreResults() && (getUpdateCount() == -1)

                public void setFetchDirection(int direction)
                       throws java.sql.SQLException
                Gives the driver a hint as to the direction in which rows will be processed in ResultSet objects created using this Statement object. The default value is ResultSet.FETCH_FORWARD.

                Note that this method sets the default fetch direction for result sets generated by this Statement object. Each result set has its own methods for getting and setting its own fetch direction.

                HSQLDB-Specific Information:

                Including 1.7.2, HSQLDB supports only FETCH_FORWARD.

                Setting any other value will throw an SQLException stating that the operation is not supported.

                Specified by:
                setFetchDirection in interface java.sql.Statement
                Parameters:
                direction - the initial direction for processing rows
                Throws:
                java.sql.SQLException - if a database access error occurs or the given direction is not one of ResultSet.FETCH_FORWARD, ResultSet.FETCH_REVERSE, or ResultSet.FETCH_UNKNOWN

                HSQLDB throws for all values except FETCH_FORWARD

                Retrieves the direction for fetching rows from database tables that is the default for result sets generated from this Statement object. If this Statement object has not set a fetch direction by calling the method setFetchDirection, the return value is implementation-specific.

                HSQLDB-Specific Information:

                Including 1.7.2, HSQLDB always returns FETCH_FORWARD.

                Gives the JDBC driver a hint as to the number of rows that should be fetched from the database when more rows are needed. The number of rows specified affects only result sets created using this statement. If the value specified is zero, then the hint is ignored. The default value is zero.

                HSQLDB-Specific Information:

                Including 1.7.2, calls to this method are ignored; HSQLDB fetches each result completely as part of executing its statement.

                Retrieves the result set concurrency for ResultSet objects generated by this Statement object.

                HSQLDB-Specific Information:

                Including 1.7.2, HSQLDB supports only CONCUR_READ_ONLY concurrency.

                public void addBatch(java.lang.String sql)
              throws java.sql.SQLException
                Adds the given SQL command to the current list of commmands for this Statement object. The commands in this list can be executed as a batch by calling the method executeBatch.

                NOTE: This method is optional.

                Empties this Statement object's current list of SQL commands.

                NOTE: This method is optional.

                HSQLDB-Specific Information:

                public int[] executeBatch()
                   throws java.sql.SQLException
                Submits a batch of commands to the database for execution and if all commands execute successfully, returns an array of update counts. The int elements of the array that is returned are ordered to correspond to the commands in the batch, which are ordered according to the order in which they were added to the batch. The elements in the array returned by the method executeBatch may be one of the following:
                1. A number greater than or equal to zero -- indicates that the command was processed successfully and is an update count giving the number of rows in the database that were affected by the command's execution
                2. A value of SUCCESS_NO_INFO -- indicates that the command was processed successfully but that the number of rows affected is unknown

                  If one of the commands in a batch update fails to execute properly, this method throws a BatchUpdateException, and a JDBC driver may or may not continue to process the remaining commands in the batch. However, the driver's behavior must be consistent with a particular DBMS, either always continuing to process commands or never continuing to process commands. If the driver continues processing after a failure, the array returned by the method BatchUpdateException.getUpdateCounts will contain as many elements as there are commands in the batch, and at least one of the elements will be the following:

                3. A value of EXECUTE_FAILED -- indicates that the command failed to execute successfully and occurs only if a driver continues to process commands after a command fails

                A driver is not required to implement this method. The possible implementations and return values have been modified in the Java 2 SDK, Standard Edition, version 1.3 to accommodate the option of continuing to proccess commands in a batch update after a BatchUpdateException obejct has been thrown.

                HSQLDB-Specific Information:

                Starting with HSQLDB 1.7.2, this feature is supported.

                HSQLDB stops execution of commands in a batch when one of the commands results in an exception. The size of the returned array equals the number of commands that were executed successfully.

                When the product is built under the JAVA1 target, an exception is never thrown and it is the responsibility of the client software to check the size of the returned update count array to determine if any batch items failed. To build and run under the JAVA2 target, JDK/JRE 1.3 or higher must be used.

                Specified by:
                executeBatch in interface java.sql.Statement
                Returns:
                an array of update counts containing one element for each command in the batch. The elements of the array are ordered according to the order in which commands were added to the batch.
                Throws:
                java.sql.SQLException - if a database access error occurs or the driver does not support batch statements. Throws BatchUpdateException (a subclass of java.sql.SQLException) if one of the commands sent to the database fails to execute properly or attempts to return a result set.

                org.hsqldb.jdbc
                Class jdbcPreparedStatement

                java.lang.Object
  extended byorg.hsqldb.jdbc.jdbcStatement
      extended byorg.hsqldb.jdbc.jdbcPreparedStatement
                All Implemented Interfaces:
                java.sql.PreparedStatement, java.sql.Statement
                Direct Known Subclasses:
                jdbcCallableStatement
                public class jdbcPreparedStatement
                extends jdbcStatement
                implements java.sql.PreparedStatement

                An object that represents a precompiled SQL statement.

                An SQL statement is precompiled and stored in a PreparedStatement object. This object can then be used to efficiently execute this statement multiple times.

                Note: The setter methods (setShort, setString, and so on) for setting IN parameter values must specify types that are compatible with the defined SQL type of the input parameter. For instance, if the IN parameter has SQL type INTEGER, then the method setInt should be used.

                If arbitrary parameter type conversions are required, the method setObject should be used with a target SQL type.

                In the following example of setting a parameter, con represents an active connection: 

                 PreparedStatement pstmt = con.prepareStatement("UPDATE EMPLOYEES
                               SET SALARY = ? WHERE ID = ?");
 pstmt.setBigDecimal(1, 153833.00)
 pstmt.setInt(2, 110592)

                HSQLDB-Specific Information:

                Starting with HSQLDB 1.7.2, jdbcPreparedStatement objects are backed by a true compiled parameteric representation. Hence, there are now significant performance gains to be had by using a jdbcPreparedStatement object in preference to a jdbcStatement object, if a short-running SQL statement is to be executed more than a small number of times.

                When it can be otherwise avoided, it is to be considered poor practice to fully prepare (construct), parameterize, execute, fetch and close a jdbcPreparedStatement object for each execution cycle. Indeed, under HSQLDB 1.8.0, this practice is likely to be noticably less performant for short-running statements than the equivalent process using jdbcStatement objects, albeit far more convenient, less error prone and certainly much less resource-intensive, especially when large binary and character values are involved, due to the optimized parameterization facility.

                Instead, when developing an application that is not totally oriented toward the execution of ad hoc SQL, it is recommended to expend some effort toward identifing the SQL statements that are good candidates for regular reuse and adapting the structure of the application accordingly. Often, this is done by recording the text of candidate SQL statements in an application resource object (which has the nice side-benefit of isolating and hiding differences in SQL dialects across different drivers) and caching for possible reuse the PreparedStatement objects derived from the recorded text.

                Multi thread use:

                A PreparedStatement object is stateful and should not normally be shared by multiple threads. If it has to be shared, the calls to set the parameters, calls to add batch statements, the execute call and any post-execute calls should be made within a block synchronized on the PreparedStatement Object.

                JRE 1.1.x Notes:

                In general, JDBC 2 support requires Java 1.2 and above, and JDBC3 requires Java 1.4 and above. In HSQLDB, support for methods introduced in different versions of JDBC depends on the JDK version used for compiling and building HSQLDB.

                Since 1.7.0, it is possible to build the product so that all JDBC 2 methods can be called while executing under the version 1.1.x Java Runtime EnvironmentTM. However, in addition to requiring explicit casts to the org.hsqldb.jdbcXXX interface implementations, some of these method calls require int values that are defined only in the JDBC 2 or greater version of ResultSet interface. For this reason, when the product is compiled under JDK 1.1.x, these values are defined in jdbcResultSet.

                In a JRE 1.1.x environment, calling JDBC 2 methods that take or return the JDBC2-only ResultSet values can be achieved by referring to them in parameter specifications and return value comparisons, respectively, as follows: 

                 jdbcResultSet.FETCH_FORWARD
 jdbcResultSet.TYPE_FORWARD_ONLY
 jdbcResultSet.TYPE_SCROLL_INSENSITIVE
 jdbcResultSet.CONCUR_READ_ONLY
 // etc.
                However, please note that code written in such a manner will not be compatible for use with other JDBC 2 drivers, since they expect and use ResultSet, rather than jdbcResultSet. Also note, this feature is offered solely as a convenience to developers who must work under JDK 1.1.x due to operating constraints, yet wish to use some of the more advanced features available under the JDBC 2 specification.

                setEscapeProcessing

                public void setEscapeProcessing(boolean enable)
                         throws java.sql.SQLException
                Sets escape processing on or off.

                HSQLDB-Specific Information:

                Since 1.7.0, the implementation follows the standard behaviour by overriding the same method in jdbcStatement class.

                In other words, calling this method has no effect.

                Specified by:
                setEscapeProcessing in interface java.sql.Statement
                Overrides:
                setEscapeProcessing in class jdbcStatement
                Parameters:
                enable - true to enable escape processing; false to disable it
                Throws:
                java.sql.SQLException - if a database access error occurs

                execute

                public boolean execute()
                throws java.sql.SQLException
                Executes the SQL statement in this PreparedStatement object, which may be any kind of SQL statement. Some prepared statements return multiple results; the execute method handles these complex statements as well as the simpler form of statements handled by the methods executeQueryand executeUpdate.

                The execute method returns a boolean to indicate the form of the first result. You must call either the method getResultSet or getUpdateCount to retrieve the result; you must call getMoreResults to move to any subsequent result(s).

                HSQLDB-Specific Information:

                Including 1.8.0, prepared statements do not generate multiple fetchable results.

                In future versions, it will be possible that statements generate multiple fetchable results under certain conditions.

                Specified by:
                execute in interface java.sql.PreparedStatement
                Returns:
                true if the first result is a ResultSet object; false if the first result is an update count or there is no result
                Throws:
                java.sql.SQLException - if a database access error occurs or an argument is supplied to this method

                executeQuery

                public java.sql.ResultSet executeQuery()
                                throws java.sql.SQLException
                Executes the SQL query in this PreparedStatement object and returns the ResultSet object generated by the query.

                Specified by:
                executeQuery in interface java.sql.PreparedStatement
                Returns:
                a ResultSet object that contains the data produced by the query; never null
                Throws:
                java.sql.SQLException - if a database access error occurs or the SQL statement does not return a ResultSet object

                executeUpdate

                public int executeUpdate()
                  throws java.sql.SQLException
                Executes the SQL statement in this PreparedStatement object, which must be an SQL INSERT, UPDATE or DELETE statement; or an SQL statement that returns nothing, such as a DDL statement.

                Specified by:
                executeUpdate in interface java.sql.PreparedStatement
                Returns:
                either (1) the row count for INSERT, UPDATE, or DELETE statements or (2) 0 for SQL statements that return nothing
                Throws:
                java.sql.SQLException - if a database access error occurs or the SQL statement returns a ResultSet object

                executeBatch

                public int[] executeBatch()
                   throws java.sql.SQLException
                Submits a batch of commands to the database for execution and if all commands execute successfully, returns an array of update counts. The int elements of the array that is returned are ordered to correspond to the commands in the batch, which are ordered according to the order in which they were added to the batch. The elements in the array returned by the method executeBatch may be one of the following:
                1. A number greater than or equal to zero -- indicates that the command was processed successfully and is an update count giving the number of rows in the database that were affected by the command's execution
                2. A value of SUCCESS_NO_INFO -- indicates that the command was processed successfully but that the number of rows affected is unknown

                  If one of the commands in a batch update fails to execute properly, this method throws a BatchUpdateException, and a JDBC driver may or may not continue to process the remaining commands in the batch. However, the driver's behavior must be consistent with a particular DBMS, either always continuing to process commands or never continuing to process commands. If the driver continues processing after a failure, the array returned by the method BatchUpdateException.getUpdateCounts will contain as many elements as there are commands in the batch, and at least one of the elements will be the following:

                3. A value of EXECUTE_FAILED -- indicates that the command failed to execute successfully and occurs only if a driver continues to process commands after a command fails

                A driver is not required to implement this method. The possible implementations and return values have been modified in the Java 2 SDK, Standard Edition, version 1.3 to accommodate the option of continuing to proccess commands in a batch update after a BatchUpdateException obejct has been thrown.

                HSQLDB-Specific Information:

                Starting with HSQLDB 1.7.2, this feature is supported.

                HSQLDB stops execution of commands in a batch when one of the commands results in an exception. The size of the returned array equals the number of commands that were executed successfully.

                When the product is built under the JAVA1 target, an exception is never thrown and it is the responsibility of the client software to check the size of the returned update count array to determine if any batch items failed. To build and run under the JAVA2 target, JDK/JRE 1.3 or higher must be used.

                Specified by:
                executeBatch in interface java.sql.Statement
                Overrides:
                executeBatch in class jdbcStatement
                Returns:
                an array of update counts containing one element for each command in the batch. The elements of the array are ordered according to the order in which commands were added to the batch.
                Throws:
                java.sql.SQLException - if a database access error occurs or the driver does not support batch statements. Throws BatchUpdateException (a subclass of java.sql.SQLException) if one of the commands sent to the database fails to execute properly or attempts to return a result set.

                    int sqlType)
             throws java.sql.SQLException
                Sets the designated parameter to SQL NULL.

                Note: You must specify the parameter's SQL type.

                HSQLDB-Specific Information:

                HSQLDB ignores the sqlType argument.

              throws java.sql.SQLException
                Sets the designated parameter to the given Java float value. The driver converts this to an SQL FLOAT value when it sends it to the database.

                HSQLDB-Specific Information:

                Since 1.7.1, HSQLDB handles Java positive/negative Infinity and NaN float values consistent with the Java Language Specification; these special values are now correctly stored to and retrieved from the database.

                   throws java.sql.SQLException
                Sets the designated parameter to the given java.math.BigDecimal value. The driver converts this to an SQL NUMERIC value when it sends it to the database.

                Specified by:
                setBigDecimal in interface java.sql.PreparedStatement
                Parameters:

                      java.lang.String x)
               throws java.sql.SQLException
                Sets the designated parameter to the given Java String value. The driver converts this to an SQL VARCHAR or LONGVARCHAR value (depending on the argument's size relative to the driver's limits on VARCHAR values) when it sends it to the database.

                HSQLDB-Specific Information:

                Including 1.7.2, HSQLDB stores all XXXCHAR values as java.lang.String objects; there is no appreciable difference between CHAR, VARCHAR and LONGVARCHAR.

                Specified by:
                setString in interface java.sql.PreparedStatement
                Parameters:

              throws java.sql.SQLException
                Sets the designated parameter to the given Java array of bytes. The driver converts this to an SQL VARBINARY or LONGVARBINARY (depending on the argument's size relative to the driver's limits on VARBINARY values) when it sends it to the database.

                HSQLDB-Specific Information:

                Including 1.7.2, HSQLDB stores all XXXBINARY values the same way; there is no appreciable difference between BINARY, VARBINARY and LONGVARBINARY.

                Specified by:
                setBytes in interface java.sql.PreparedStatement
                Parameters:

             throws java.sql.SQLException
                Sets the designated parameter to the given java.sql.Date value. The driver converts this to an SQL DATE value when it sends it to the database.

                Specified by:
                setDate in interface java.sql.PreparedStatement
                Parameters:

                    java.sql.Time x)
             throws java.sql.SQLException
                Sets the designated parameter to the given java.sql.Time value. The driver converts this to an SQL TIME value when it sends it to the database.

                Specified by:
                setTime in interface java.sql.PreparedStatement
                Parameters:

                  throws java.sql.SQLException
                Sets the designated parameter to the given java.sql.Timestamp value. The driver converts this to an SQL TIMESTAMP value when it sends it to the database.

                Specified by:
                setTimestamp in interface java.sql.PreparedStatement
                Parameters:
                parameterIndex - the first parameter is 1, the second is 2, ...
                x - the parameter value

                setAsciiStream

                public void setAsciiStream(int parameterIndex,
                           java.io.InputStream x,
                           int length)
                    throws java.sql.SQLException
                Sets the designated parameter to the given input stream, which will have the specified number of bytes. When a very large ASCII value is input to a LONGVARCHAR parameter, it may be more practical to send it via a java.io.InputStream. Data will be read from the stream as needed until end-of-file is reached. The JDBC driver will do any necessary conversion from ASCII to the database char format.

                Note: This stream object can either be a standard Java stream object or your own subclass that implements the standard interface.

                HSQLDB-Specific Information:

                This method uses the default platform character encoding to convert bytes from the stream into the characters of a String. In the future this is likely to change to always treat the stream as ASCII.

                Before HSQLDB 1.7.0, setAsciiStream and setUnicodeStream were identical.

                Specified by:
                setAsciiStream in interface java.sql.PreparedStatement
                Parameters:
                parameterIndex - the first parameter is 1, the second is 2, ...
                x - the Java input stream that contains the ASCII parameter value
                length - the number of bytes in the stream
                Throws:
                java.sql.SQLException - if a database access error occurs

                setUnicodeStream

                public void setUnicodeStream(int parameterIndex,
                             java.io.InputStream x,
                             int length)
                      throws java.sql.SQLException
                Deprecated. Sun does not include a reason, but presumably this is because setCharacterStream is now prefered

                Sets the designated parameter to the given input stream, which will have the specified number of bytes. A Unicode character has two bytes, with the first byte being the high byte, and the second being the low byte. When a very large Unicode value is input to a LONGVARCHAR parameter, it may be more practical to send it via a java.io.InputStream object. The data will be read from the stream as needed until end-of-file is reached. The JDBC driver will do any necessary conversion from Unicode to the database char format.

                Note: This stream object can either be a standard Java stream object or your own subclass that implements the standard interface.

                HSQLDB-Specific Information:

                Since 1.7.0, this method complies with behavior as defined by the JDBC3 specification.

                Specified by:
                setUnicodeStream in interface java.sql.PreparedStatement
                Parameters:
                parameterIndex - the first parameter is 1, the second is 2, ...
                x - a java.io.InputStream object that contains the Unicode parameter value as two-byte Unicode characters
                length - the number of bytes in the stream
                Throws:
                java.sql.SQLException - if a database access error occurs

                setBinaryStream

                public void setBinaryStream(int parameterIndex,
                            java.io.InputStream x,
                            int length)
                     throws java.sql.SQLException
                Sets the designated parameter to the given input stream, which will have the specified number of bytes. When a very large binary value is input to a LONGVARBINARY parameter, it may be more practical to send it via a java.io.InputStream object. The data will be read from the stream as needed until end-of-file is reached.

                Note: This stream object can either be a standard Java stream object or your own subclass that implements the standard interface.

                HSQLDB-Specific Information:

                Since 1.7.2, this method works according to the standard.

                Specified by:
                setBinaryStream in interface java.sql.PreparedStatement
                Parameters:
                parameterIndex - the first parameter is 1, the second is 2, ...
                x - the java input stream which contains the binary parameter value
                length - the number of bytes in the stream
                Throws:
                java.sql.SQLException - if a database access error occurs

                clearParameters

                public void clearParameters()
                     throws java.sql.SQLException
                Clears the current parameter values immediately.

                In general, parameter values remain in force for repeated use of a statement. Setting a parameter value automatically clears its previous value. However, in some cases it is useful to immediately release the resources used by the current parameter values; this can be done by calling the method clearParameters.

                Specified by:
                clearParameters in interface java.sql.PreparedStatement
                Throws:
                java.sql.SQLException - if a database access error occurs

                setObject

                public void setObject(int parameterIndex,
                      java.lang.Object x,
                      int targetSqlType,
                      int scale)
               throws java.sql.SQLException
                Sets the value of the designated parameter with the given object.

                The second argument must be an object type; for integral values, the java.lang equivalent objects should be used.

                The given Java object will be converted to the given targetSqlType before being sent to the database. If the object has a custom mapping (is of a class implementing the interface SQLData), the JDBC driver should call the method SQLData.writeSQL to write it to the SQL data stream. If, on the other hand, the object is of a class implementing Ref, Blob, Clob, Struct, or Array, the driver should pass it to the database as a value of the corresponding SQL type.

                Note that this method may be used to pass database-specific abstract data types.

                HSQLDB-Specific Information:

                Inculding 1.7.1,this method was identical to setObject(int, Object, int). That is, this method simply called setObject(int, Object, int), ignoring the scale specification.

                Since 1.7.2, this method supports the conversions listed in the conversion table B-5 of the JDBC 3 specification. The scale argument is not used.

                Specified by:
                setObject in interface java.sql.PreparedStatement
                Parameters:
                parameterIndex - the first parameter is 1, the second is 2, ...
                x - the object containing the input parameter value
                targetSqlType - the SQL type (as defined in java.sql.Types) to be sent to the database. The scale argument may further qualify this type.
                scale - for java.sql.Types.DECIMAL or java.sql.Types.NUMERIC types, this is the number of digits after the decimal point. For all other types, this value will be ignored.

                Up to and including HSQLDB 1.7.0, this parameter is ignored.

                Throws:
                java.sql.SQLException - if a database access error occurs

                      int targetSqlType)
               throws java.sql.SQLException
                Sets the value of the designated parameter with the given object. This method is like the method setObject above, except that it assumes a scale of zero.

                HSQLDB-Specific Information:

                Since 1.7.2, this method supports conversions listed in the conversion table B-5 of the JDBC 3 specification.

                Specified by:
                setObject in interface java.sql.PreparedStatement
                Parameters:
                parameterIndex - the first parameter is 1, the second is 2, ...
                x - the object containing the input parameter value
                targetSqlType - the SQL type (as defined in java.sql.Types) to be sent to the database
                Throws:

                      java.lang.Object x)
               throws java.sql.SQLException
                Sets the value of the designated parameter using the given object.

                The second parameter must be of type Object; therefore, the java.lang equivalent objects should be used for built-in types.

                The JDBC specification specifies a standard mapping from Java Object types to SQL types. The given argument will be converted to the corresponding SQL type before being sent to the database.

                Note that this method may be used to pass datatabase- specific abstract data types, by using a driver-specific Java type. If the object is of a class implementing the interface SQLData, the JDBC driver should call the method SQLData.writeSQL to write it to the SQL data stream. If, on the other hand, the object is of a class implementing Ref, Blob, Clob, Struct, or Array, the driver should pass it to the database as a value of the corresponding SQL type.

                This method throws an exception if there is an ambiguity, for example, if the object is of a class implementing more than one of the interfaces named above.

                HSQLDB-Specific Information:

                Since 1.7.2, this method supports conversions listed in the conversion table B-5 of the JDBC 3 specification.

                        throws java.sql.SQLException
                Sets the designated parameter to the given Reader object, which is the given number of characters long. When a very large UNICODE value is input to a LONGVARCHAR parameter, it may be more practical to send it via a java.io.Reader object. The data will be read from the stream as needed until end-of-file is reached. The JDBC driver will do any necessary conversion from UNICODE to the database char format.

                Note: This stream object can either be a standard Java stream object or your own subclass that implements the standard interface.

                HSQLDB-Specific Information:

                HSQLDB stores CHARACTER and related SQL types as Unicode so this method does not perform any conversion.

             throws java.sql.SQLException
                Sets the designated parameter to the given Blob object. The driver converts this to an SQL BLOB value when it sends it to the database.

                HSQLDB-Specific Information:

                Previous to 1.7.2, this feature was not supported.

                Since 1.7.2, setBlob is supported. With 1.7.2, setting Blob objects is limited to those of length less than or equal to Integer.MAX_VALUE. In 1.7.2, setBlob(i,x) is roughly equivalent (null and length handling not shown) to: 

                 setBinaryStream(i, x.getBinaryStream(), (int) x.length());

                Specified by:

                                       throws java.sql.SQLException
                Retrieves a ResultSetMetaData object that contains information about the columns of the ResultSet object that will be returned when this PreparedStatement object is executed.

                Because a PreparedStatement object is precompiled, it is possible to know about the ResultSet object that it will return without having to execute it. Consequently, it is possible to invoke the method getMetaData on a PreparedStatement object rather than waiting to execute it and then invoking the ResultSet.getMetaData method on the ResultSet object that is returned.

                NOTE: Using this method may be expensive for some drivers due to the lack of underlying DBMS support.

                HSQLDB-Specific Information:

                Since 1.7.2, this feature is supported. If the statement generates an update count, then null is returned.

                Specified by:
                getMetaData in interface java.sql.PreparedStatement
                Returns:

             throws java.sql.SQLException
                Sets the designated parameter to SQL NULL. This version of the method setNull should be used for user-defined types and REF type parameters. Examples of user-defined types include: STRUCT, DISTINCT, JAVA_OBJECT, and named array types.

                Note: To be portable, applications must give the SQL type code and the fully-qualified SQL type name when specifying a NULL user-defined or REF parameter. In the case of a user-defined type the name is the type name of the parameter itself. For a REF parameter, the name is the type name of the referenced type. If a JDBC driver does not need the type code or type name information, it may ignore it. Although it is intended for user-defined and Ref parameters, this method may be used to set a null parameter of any JDBC type. If the parameter does not have a user-defined or REF type, the given typeName is ignored.

                HSQLDB-Specific Information:

                HSQLDB ignores the sqlType and typeName arguments.

                java.sql.Clob

                implements java.sql.Clob

                The mapping in the JavaTM programming language for the SQL CLOB type.

                Provides methods for getting the length of an SQL CLOB (Character Large Object) value, for materializing a CLOB value on the client, and for searching for a substring or CLOB object within a CLOB value.

                HSQLDB-Specific Information:

                Including 1.8.x, the HSQLDB driver does not implement Clob using an SQL locator(CLOB). That is, an HSQLDB Clob object does not contain a logical pointer to SQL CLOB data; rather it directly contains an immutable representation of the data (a String object). As a result, an HSQLDB Clob object itself is valid beyond the duration of the transaction in which is was created, although it does not necessarily represent a corresponding value on the database.

                Currently, the interface methods for updating a CLOB value are unsupported. However, the truncate method is supported for local use.

                Constructor Detail

                jdbcClob

                public jdbcClob(java.lang.String data)
         throws java.sql.SQLException
                Constructs a new jdbcClob object wrapping the given character sequence.

                This constructor is used internally to retrieve result set values as Clob objects, yet it must be public to allow access from other packages. As such (in the interest of efficiency) this object maintains a reference to the given String object rather than making a copy and so it is gently suggested (in the interest of effective memory management) that extenal clients using this constructor either take pause to consider the implications or at least take care to provide a String object whose internal character buffer is not much larger than required to represent the value.

                Parameters:
                data - the character sequence representing the Clob value
                Throws:
                java.sql.SQLException - if the argument is null
                Method Detail

                length

                public long length()
            throws java.sql.SQLException
                Retrieves the number of characters in the CLOB value designated by this Clob object.

                Specified by:
                length in interface java.sql.Clob
                Returns:
                length of the CLOB in characters
                Throws:
                java.sql.SQLException - if there is an error accessing the length of the CLOB value
                Since:
                JDK 1.2, HSQLDB 1.7.2

                getSubString

                public java.lang.String getSubString(long pos,
                                     int length)
                              throws java.sql.SQLException
                Retrieves a copy of the specified substring in the CLOB value designated by this Clob object. The substring begins at position pos and has up to length consecutive characters.

                HSQLDB-Specific Information:

                The official specification above is ambiguous in that it does not precisely indicate the policy to be observed when pos > this.length() - length. One policy would be to retrieve the characters from pos to this.length(). Another would be to throw an exception. HSQLDB observes the later policy.

                Specified by:
                getSubString in interface java.sql.Clob
                Parameters:
                pos - the first character of the substring to be extracted. The first character is at position 1.
                length - the number of consecutive characters to be copied
                Returns:
                a String that is the specified substring in the CLOB value designated by this Clob object
                Throws:
                java.sql.SQLException - if there is an error accessing the CLOB value

                Class jdbcResultSet

                java.lang.Object
  extended byorg.hsqldb.jdbc.jdbcResultSet
                All Implemented Interfaces:
                java.sql.ResultSet
                public class jdbcResultSet
                extends java.lang.Object
                implements java.sql.ResultSet

                A table of data representing a database result set, which is usually generated by executing a statement that queries the database.

                A ResultSet object maintains a cursor pointing to its current row of data. Initially the cursor is positioned before the first row. The next method moves the cursor to the next row, and because it returns false when there are no more rows in the ResultSet object, it can be used in a while loop to iterate through the result set.

                A default ResultSet object is not updatable and has a cursor that moves forward only. Thus, you can iterate through it only once and only from the first row to the last row. It is possible to produce ResultSet objects that are scrollable and/or updatable. The following code fragment, in which con is a valid Connection object, illustrates how to make a result set that is scrollable and insensitive to updates by others, and that is updatable. See ResultSet fields for other options. 

                
 Statement stmt = con.createStatement(
                            ResultSet.TYPE_SCROLL_INSENSITIVE,
                            ResultSet.CONCUR_UPDATABLE);
 ResultSet rs = stmt.executeQuery("SELECT a, b FROM TABLE2");
 // rs will be scrollable, will not show changes made by others,
 // and will be updatable
                The ResultSet interface provides getter methods (getBoolean, getLong, and so on) for retrieving column values from the current row. Values can be retrieved using either the index number of the column or the name of the column. In general, using the column index will be more efficient. Columns are numbered from 1. For maximum portability, result set columns within each row should be read in left-to-right order, and each column should be read only once.

                For the getter methods, a JDBC driver attempts to convert the underlying data to the Java type specified in the getter method and returns a suitable Java value. The JDBC specification has a table showing the allowable mappings from SQL types to Java types that can be used by the ResultSet getter methods.

                Column names used as input to getter methods are case insensitive. When a getter method is called with a column name and several columns have the same name, the value of the first matching column will be returned. The column name option is designed to be used when column names are used in the SQL query that generated the result set. For columns that are NOT explicitly named in the query, it is best to use column numbers. If column names are used, there is no way for the programmer to guarantee that they actually refer to the intended columns.

                A set of updater methods were added to this interface in the JDBC 2.0 API (JavaTM 2 SDK, Standard Edition, version 1.2). The comments regarding parameters to the getter methods also apply to parameters to the updater methods.

                The updater methods may be used in two ways:

                1. to update a column value in the current row. In a scrollable ResultSet object, the cursor can be moved backwards and forwards, to an absolute position, or to a position relative to the current row. The following code fragment updates the NAME column in the fifth row of the ResultSet object rs and then uses the method updateRow to update the data source table from which rs was derived. 
                  
 rs.absolute(5); // moves the cursor to the fifth row of rs
 rs.updateString("NAME", "AINSWORTH"); // updates the
 // NAME column of row 5 to be AINSWORTH
 rs.updateRow(); // updates the row in the data source
                2. to insert column values into the insert row. An updatable ResultSet object has a special row associated with it that serves as a staging area for building a row to be inserted. The following code fragment moves the cursor to the insert row, builds a three-column row, and inserts it into rs and into the data source table using the method insertRow. 
                  
 rs.moveToInsertRow(); // moves cursor to the insert row
 rs.updateString(1, "AINSWORTH"); // updates the
 // first column of the insert row to be AINSWORTH
 rs.updateInt(2,35); // updates the second column to be 35
 rs.updateBoolean(3, true); // updates the third row to true
 rs.insertRow();
 rs.moveToCurrentRow();

                A ResultSet object is automatically closed when the Statement object that generated it is closed, re-executed, or used to retrieve the next result from a sequence of multiple results.

                The number, types and properties of a ResultSet object's columns are provided by the ResulSetMetaData object returned by the ResultSet.getMetaData method.

                HSQLDB-Specific Information:

                A ResultSet object generated by HSQLDB is by default of ResultSet.TYPE_FORWARD_ONLY (as is standard JDBC behavior) and does not allow the use of absolute and relative positioning methods. However, since 1.7.0, if a statement is created with:

                 Statement stmt = conn.createStatement(ResultSet.TYPE_SCROLL_INSENSITIVE, ResultSet.CONCUR_READ_ONLY);
                then the ResultSet objects it produces support using all of the absolute and relative positioning methods of JDBC2 to set the position of the current row, for example:

                 rs.absolute(5);
 String fifthRowValue = rs.getString(1);
 rs.relative(4);
 String ninthRowValue = rs.getString(1);
                Note: An HSQLDB ResultSet object persists, even after its connection is closed. This is regardless of the operational mode of the Database from which it came. That is, they persist whether originating from a Server, WebServer or in-process mode Database.

                Including HSQLDB 1.7.2, there is no support for any of the methods introduced in JDBC 2 relating to updateable result sets. These methods include all updateXXX methods, as well as the insertRow(), updateRow(), deleteRow(), moveToInsertRow() (and so on) methods; invoking any such method throws an SQLException stating that the operation is not supported. JRE 1.1.x Notes:

                In general, JDBC 2 support requires Java 1.2 and above, and JDBC 3 requires Java 1.4 and above. In HSQLDB, support for methods introduced in different versions of JDBC depends on the JDK version used for compiling and building HSQLDB.

                Since 1.7.0, it is possible to build the product so that all JDBC 2 methods can be called while executing under the version 1.1.x Java Runtime EnvironmentTM. However, some of these method calls require int values that are defined only in the JDBC 2 or greater version of the ResultSet interface. For this reason, when the product is compiled under JDK 1.1.x, these values are defined here, in this class.

                In a JRE 1.1.x environment, calling JDBC 2 methods that take or return the JDBC2-only ResultSet values can be achieved by referring to them in parameter specifications and return value comparisons, respectively, as follows: 

                 jdbcResultSet.FETCH_FORWARD
 jdbcResultSet.TYPE_FORWARD_ONLY
 jdbcResultSet.TYPE_SCROLL_INSENSITIVE
 jdbcResultSet.CONCUR_READ_ONLY
 // etc.
                However, please note that code written in such a manner will not be compatible for use with other JDBC 2 drivers, since they expect and use ResultSet, rather than jdbcResultSet. Also note, this feature is offered solely as a convenience to developers who must work under JDK 1.1.x due to operating constraints, yet wish to use some of the more advanced features available under the JDBC 2 specification.

                next

                public boolean next()
             throws java.sql.SQLException
                Moves the cursor down one row from its current position. A ResultSet cursor is initially positioned before the first row; the first call to the method next makes the first row the current row; the second call makes the second row the current row, and so on.

                If an input stream is open for the current row, a call to the method next will implicitly close it. A ResultSet object's warning chain is cleared when a new row is read.

                Specified by:
                next in interface java.sql.ResultSet
                Returns:
                true if the new current row is valid; false if there are no more rows
                Throws:
                java.sql.SQLException - if a database access error occurs

                close

                public void close()
           throws java.sql.SQLException
                Releases this ResultSet object's database and JDBC resources immediately instead of waiting for this to happen when it is automatically closed.

                Note: A ResultSet object is automatically closed by the Statement object that generated it when that Statement object is closed, re-executed, or is used to retrieve the next result from a sequence of multiple results. A ResultSet object is also automatically closed when it is garbage collected.

                Specified by:
                close in interface java.sql.ResultSet

                throws java.sql.SQLException
                Reports whether the last column read had a value of SQL NULL. Note that you must first call one of the getter methods on a column to try to read its value and then call the method wasNull to see if the value read was SQL NULL.

                Specified by:
                wasNull in interface java.sql.ResultSet
                Returns:

                Retrieves the value of the designated column in the current row of this ResultSet object as a java.sql.BigDecimal in the Java programming language.

                HSQLDB-Specific Information:

                Beginning with 1.7.0, HSQLDB converts the result and sets the scale with BigDecimal.ROUND_HALF_DOWN.

                Specified by:
                getBigDecimal in interface java.sql.ResultSet
                Parameters:

                getAsciiStream

                                   throws java.sql.SQLException
                Retrieves the value of the designated column in the current row of this ResultSet object as a stream of ASCII characters. The value can then be read in chunks from the stream. This method is particularly suitable for retrieving large LONGVARCHAR values. The JDBC driver will do any necessary conversion from the database format into ASCII.

                Note: All the data in the returned stream must be read prior to getting the value of any other column. The next call to a getter method implicitly closes the stream. Also, a stream may return 0 when the method InputStream.available is called whether there is data available or not.

                HSQLDB-Specific Information:

                The limitation noted above does not apply to HSQLDB.

                In 1.6.1 and previous, getAsciiStream was identical to getUnicodeStream and both simply returned a byte stream constructed from the raw getBytes representation. Starting with 1.7.0, this has been updated to comply with the java.sql specification. When the column is of type CHAR and its variations, it requires no conversion since it is represented internally already as a Java String object. When the column is not of type CHAR and its variations, the returned stream is based on a conversion to the Java String representation of the value. In either case, the obtained stream is always equivalent to a stream of the low order bytes from the value's String representation.

                HSQLDB SQL CHAR and its variations are all Unicode strings internally, so the recommended alternatives to this method are getString, getUnicodeStream (deprecated) and new to 1.7.0: getCharacterStream (now prefered over the deprecated getUnicodeStream alternative).

                Specified by:
                getAsciiStream in interface java.sql.ResultSet
                Parameters:
                columnIndex - the first column is 1, the second is 2, ...
                Returns:
                a Java input stream that delivers the database column value as a stream of one-byte ASCII characters; if the value is SQL NULL, the value returned is null
                Throws:
                java.sql.SQLException - if a database access error occurs

                getUnicodeStream

                Deprecated. use getCharacterStream in place of getUnicodeStream

                Retrieves the value of the designated column in the current row of this ResultSet object as as a stream of two-byte Unicode characters. The first byte is the high byte; the second byte is the low byte. The value can then be read in chunks from the stream. This method is particularly suitable for retrieving large LONGVARCHARvalues. The JDBC driver will do any necessary conversion from the database format into Unicode.

                Note: All the data in the returned stream must be read prior to getting the value of any other column. The next call to a getter method implicitly closes the stream. Also, a stream may return 0 when the method InputStream.available is called, whether there is data available or not.

                Up to and including 1.6.1, getUnicodeStream (and getAsciiStream) both simply returned a byte stream constructed from the raw getBytes representation. Starting with 1.7.0, this has been corrected to comply with the java.sql specification.

                Retrieves the value of the designated column in the current row of this ResultSet object as a binary stream of uninterpreted bytes. The value can then be read in chunks from the stream. This method is particularly suitable for retrieving large LONGVARBINARY values.

                Note: All the data in the returned stream must be read prior to getting the value of any other column. The next call to a getter method implicitly closes the stream. Also, a stream may return 0 when the method InputStream.available is called whether there is data available or not.

                getTime in interface java.sql.ResultSet
                Parameters:
                columnName - the SQL name of the column
                Returns:
                the column value; if the value is SQL NULL, the value returned is null
                Throws:

                getTimestamp

                public java.sql.Timestamp getTimestamp(java.lang.String columnName)
                                throws java.sql.SQLException
                Retrieves the value of the designated column in the current row of this ResultSet object as a java.sql.Timestamp object.

                Specified by:
                getTimestamp in interface java.sql.ResultSet
                Parameters:
                columnName - the SQL name of the column
                Returns:
                the column value; if the value is SQL NULL, the value returned is null

                getAsciiStream

                public java.io.InputStream getAsciiStream(java.lang.String columnName)
                                   throws java.sql.SQLException
                Retrieves the value of the designated column in the current row of this ResultSet object as a stream of ASCII characters. The value can then be read in chunks from the stream. This method is particularly suitable for retrieving large LONGVARCHAR values. The JDBC driver will do any necessary conversion from the database format into ASCII.

                Note: All the data in the returned stream must be read prior to getting the value of any other column. The next call to a getter method implicitly closes the stream. Also, a stream may return 0 when the method available is called whether there is data available or not.

                Specified by:
                getAsciiStream in interface java.sql.ResultSet
                Parameters:
                columnName - the SQL name of the column
                Returns:
                a Java input stream that delivers the database column value as a stream of one-byte ASCII characters. If the value is SQL NULL, the value returned is null.
                Throws:
                java.sql.SQLException - if a database access error occurs

                Deprecated. use getCharacterStream instead

                Retrieves the value of the designated column in the current row of this ResultSet object as a stream of two-byte Unicode characters. The first byte is the high byte; the second byte is the low byte. The value can then be read in chunks from the stream. This method is particularly suitable for retrieving large LONGVARCHAR values. The JDBC technology-enabled driver will do any necessary conversion from the database format into Unicode.

                Note: All the data in the returned stream must be read prior to getting the value of any other column. The next call to a getter method implicitly closes the stream. Also, a stream may return 0 when the method InputStream.available is called, whether there is data available or not.

                Specified by:
                getUnicodeStream in interface java.sql.ResultSet
                Parameters:
                columnName - the SQL name of the column
                Returns:
                a Java input stream that delivers the database column value as a stream of two-byte Unicode characters. If the value is SQL NULL, the value returned is null.
                Throws:
                java.sql.SQLException - if a database access error occurs

                                    throws java.sql.SQLException
                Retrieves the value of the designated column in the current row of this ResultSet object as a stream of uninterpreted bytes. The value can then be read in chunks from the stream. This method is particularly suitable for retrieving large LONGVARBINARY values.

                Note: All the data in the returned stream must be read prior to getting the value of any other column. The next call to a getter method implicitly closes the stream. Also, a stream may return 0 when the method available is called whether there is data available or not.

                Specified by:
                getBinaryStream in interface java.sql.ResultSet
                Parameters:
                columnName - the SQL name of the column
                Returns:
                a Java input stream that delivers the database column value as a stream of uninterpreted bytes; if the value is SQL NULL, the result is null
                Throws:

                getWarnings

                public java.sql.SQLWarning getWarnings()
                                throws java.sql.SQLException
                Retrieves the first warning reported by calls on this ResultSet object. Subsequent warnings on this ResultSet object will be chained to the SQLWarning object that this method returns.

                The warning chain is automatically cleared each time a new row is read. This method may not be called on a ResultSet object that has been closed; doing so will cause an SQLException to be thrown.

                Note: This warning chain only covers warnings caused by ResultSet methods. Any warning caused by Statement methods (such as reading OUT parameters) will be chained on the Statement object.

                HSQLDB-Specific Information:

                Up to and including 1.7.1, HSQLDB does not produce SQLWarning objects. This method always returns null.

                Specified by:
                getWarnings in interface java.sql.ResultSet
                Returns:
                the first SQLWarning object reported or null if there are none

                Up to and including 1.7.1, HSQLDB always returns null.

                Throws:
                java.sql.SQLException - if a database access error occurs or this method is called on a closed result set

                clearWarnings

                public void clearWarnings()
                   throws java.sql.SQLException
                Clears all warnings reported on this ResultSet object. After this method is called, the method getWarnings returns null until a new warning is reported for this ResultSet object.

                HSQLDB-Specific Information:

                Including 1.7.1, HSQLDB does not produce SQLWarning objects on any ResultSet object warning chain; calls to this method are ignored.

                Specified by:
                clearWarnings in interface java.sql.ResultSet
                Throws:
                java.sql.SQLException - if a database access error occurs

                getCursorName

                public java.lang.String getCursorName()
                               throws java.sql.SQLException
                Retrieves the name of the SQL cursor used by this ResultSet object.

                In SQL, a result table is retrieved through a cursor that is named. The current row of a result set can be updated or deleted using a positioned update/delete statement that references the cursor name. To insure that the cursor has the proper isolation level to support update, the cursor's SELECT statement should be of the form SELECT FOR UPDATE. If FOR UPDATE is omitted, the positioned updates may fail.

                The JDBC API supports this SQL feature by providing the name of the SQL cursor used by a ResultSet object. The current row of a ResultSet object is also the current row of this SQL cursor.

                Note: If positioned update is not supported, a SQLException is thrown.

                HSQLDB-Specific Information:

                Including 1.7.2, HSQLDB does not support this feature.

                Calling this method always throws an SQLException, stating that the operation is not supported.

                Specified by:
                getCursorName in interface java.sql.ResultSet
                Returns:
                the SQL name for this ResultSet object's cursor
                Throws:
                java.sql.SQLException - if a database access error occurs

                getMetaData

                public java.sql.ResultSetMetaData getMetaData()
                                       throws java.sql.SQLException
                Retrieves the number, types and properties of this ResultSet object's columns.

                HSQLDB-Specific Information:

                Example:

                The following code fragment creates a ResultSet object rs, creates a ResultSetMetaData object rsmd, and uses rsmd to find out how many columns rs has and whether the first column in rs can be used in a WHERE clause. 

                 ResultSet         rs              = stmt.executeQuery("SELECT a, b, c FROM TABLE2");
 ResultSetMetaData rsmd = rs.getMetaData();
                
 int numberOfColumns = rsmd.getColumnCount();
                
 boolean b = rsmd.isSearchable(1);
                Warning:

                Including 1.7.1, HSQLDB did not generate accurate ResultSetMetaData. Below were the the most important methods to consider:

                1. isAutoIncrement(int) always returned false
                2. isCurrency(int) always returned false
                3. isNullable(int) always returned columnNullableUnknown
                4. getColumnDisplaySize(int) returned zero for all valid column numbers
                5. getSchemaName(int) always returned ""
                6. getPrecision(int) always returned zero
                7. getScale(int) always returned zero
                8. getCatalogName(int) always returned ""

                Starting with 1.7.2, ResultSetMetaData has been split out into its own interface implemenation (jdbcResultSetMetaData), support has been improved considerably for a number of methods and behaviour has been altered slightly in many areas.

                Specified by:
                getMetaData in interface java.sql.ResultSet
                Returns:
                the description of this ResultSet object's columns
                Throws:

                getObject

                public java.lang.Object getObject(int columnIndex)
                           throws java.sql.SQLException
                Gets the value of the designated column in the current row of this ResultSet object as an Object in the Java programming language.

                This method will return the value of the given column as a Java object. The type of the Java object will be the default Java object type corresponding to the column's SQL type, following the mapping for built-in types specified in the JDBC specification. If the value is an SQL NULL, the driver returns a Java null.

                This method may also be used to read datatabase-specific abstract data types. In the JDBC 2.0 API, the behavior of method getObject is extended to materialize data of SQL user-defined types. When a column contains a structured or distinct value, the behavior of this method is as if it were a call to: getObject(columnIndex, this.getStatement().getConnection().getTypeMap()).

                isLast

                public boolean isLast()
               throws java.sql.SQLException
                Retrieves whether the cursor is on the last row of this ResultSet object. Note: Calling the method isLast may be expensive because the JDBC driver might need to fetch ahead one row in order to determine whether the current row is the last row in the result set.

                HSQLDB-Specific Information:

                Including 1.7.2, this method is not terribly expensive; the entire result is fetched internally before this object is returned to a caller.

                public boolean absolute(int row)
                 throws java.sql.SQLException
                Moves the cursor to the given row number in this ResultSet object.

                If the row number is positive, the cursor moves to the given row number with respect to the beginning of the result set. The first row is row 1, the second is row 2, and so on.

                If the given row number is negative, the cursor moves to an absolute row position with respect to the end of the result set. For example, calling the method absolute(-1) positions the cursor on the last row; calling the method absolute(-2) moves the cursor to the next-to-last row, and so on.

                An attempt to position the cursor beyond the first/last row in the result set leaves the cursor before the first row or after the last row.

                Note: Calling absolute(1) is the same as calling first(). Calling absolute(-1) is the same as calling last().

                Specified by:
                absolute in interface java.sql.ResultSet
                Parameters:
                row - the number of the row to which the cursor should move. A positive number indicates the row number counting from the beginning of the result set; a negative number indicates the row number counting from the end of the result set
                Returns:
                true if the cursor is on the result set; false otherwise
                Throws:

                public boolean relative(int rows)
                 throws java.sql.SQLException
                Moves the cursor a relative number of rows, either positive or negative. Attempting to move beyond the first/last row in the result set positions the cursor before/after the the first/last row. Calling relative(0) is valid, but does not change the cursor position.

                Note: Calling the method relative(1) is identical to calling the method next() and calling the method relative(-1) is identical to calling the method previous().

                Specified by:
                relative in interface java.sql.ResultSet
                Parameters:

                       throws java.sql.SQLException
                Gives a hint as to the direction in which the rows in this ResultSet object will be processed. The initial value is determined by the Statement object that produced this ResultSet object. The fetch direction may be changed at any time.

                HSQLDB-Specific Information:

                Including 1.7.2, HSQLDB builds and returns result sets as a whole; this method does nothing. However, as mandated by the JDBC standard, an SQLException is thrown if the result set type is TYPE_FORWARD_ONLY and a fetch direction other than FETCH_FORWARD is requested.

                Specified by:
                setFetchDirection in interface java.sql.ResultSet
                Parameters:
                direction - an int specifying the suggested fetch direction; one of ResultSet.FETCH_FORWARD, ResultSet.FETCH_REVERSE, or ResultSet.FETCH_UNKNOWN
                Throws:
                java.sql.SQLException - if a database access error occurs or the result set type is TYPE_FORWARD_ONLY and the fetch direction is not FETCH_FORWARD

                Retrieves the fetch direction for this ResultSet object.

                HSQLDB-Specific Information:

                Including 1.7.2, HSQLDB builds and returns result sets as a whole; this method always returns FETCH_FORWARD, but the value has no real meaning.

                Specified by:
                getFetchDirection in interface java.sql.ResultSet
                Returns:

                  throws java.sql.SQLException
                Gives the JDBC driver a hint as to the number of rows that should be fetched from the database when more rows are needed for this ResultSet object. If the fetch size specified is zero, the JDBC driver ignores the value and is free to make its own best guess as to what the fetch size should be. The default value is set by the Statement object that created the result set. The fetch size may be changed at any time.

                HSQLDB-Specific Information:

                Including 1.7.2, HSQLDB does not support and thus never returns ResultSet.TYPE_SCROLL_SENSITIVE.

                refreshRow

                public void refreshRow()
                throws java.sql.SQLException
                Refreshes the current row with its most recent value in the database. This method cannot be called when the cursor is on the insert row.

                The refreshRow method provides a way for an application to explicitly tell the JDBC driver to refetch a row(s) from the database. An application may want to call refreshRow when caching or prefetching is being done by the JDBC driver to fetch the latest value of a row from the database. The JDBC driver may actually refresh multiple rows at once if the fetch size is greater than one.

                All values are refetched subject to the transaction isolation level and cursor sensitivity. If refreshRow is called after calling an updater method, but before calling the method updateRow, then the updates made to the row are lost. Calling the method refreshRow frequently will likely slow performance.

                Cancels the updates made to the current row in this ResultSet object. This method may be called after calling an updater method(s) and before calling the method updateRow to roll back the updates made to a row. If no updates have been made or updateRow has already been called, this method has no effect.

                Moves the cursor to the insert row. The current cursor position is remembered while the cursor is positioned on the insert row. The insert row is a special row associated with an updatable result set. It is essentially a buffer where a new row may be constructed by calling the updater methods prior to inserting the row into the result set. Only the updater, getter, and insertRow methods may be called when the cursor is on the insert row. All of the columns in a result set must be given a value each time this method is called before calling insertRow. An updater method must be called before a getter method can be called on a column value.

                org.hsqldb.jdbc
                Class jdbcCallableStatement

                java.lang.Object
  extended byorg.hsqldb.jdbc.jdbcStatement
      extended byorg.hsqldb.jdbc.jdbcPreparedStatement
          extended byorg.hsqldb.jdbc.jdbcCallableStatement
                All Implemented Interfaces:
                java.sql.CallableStatement, java.sql.PreparedStatement, java.sql.Statement
                public class jdbcCallableStatement
                extends jdbcPreparedStatement
                implements java.sql.CallableStatement

                The interface used to execute SQL stored procedures. The JDBC API provides a stored procedure SQL escape syntax that allows stored procedures to be called in a standard way for all RDBMSs. This escape syntax has one form that includes a result parameter and one that does not. If used, the result parameter must be registered as an OUT parameter. The other parameters can be used for input, output or both. Parameters are referred to sequentially, by number, with the first parameter being 1. 

                   {?= call <procedure-name>[<arg1>,<arg2>, ...]}
   {call <procedure-name>[<arg1>,<arg2>, ...]}

                IN parameter values are set using the set methods inherited from PreparedStatement. The type of all OUT parameters must be registered prior to executing the stored procedure; their values are retrieved after execution via the get methods provided here.

                A CallableStatement can return one ResultSet object or multiple ResultSet objects. Multiple ResultSet objects are handled using operations inherited from Statement.

                For maximum portability, a call's ResultSet objects and update counts should be processed prior to getting the values of output parameters.

                HSQLDB-Specific Information:

                Since 1.7.2, the JDBC CallableStatement interface implementation has been broken out of the jdbcPreparedStatement class into this one.

                With 1.7.2, some of the previously unsupported features of this interface are now supported, such as the parameterName-based setter methods.

                More importantly, jdbcCallableStatement objects are now backed by a true compiled parameteric representation. Hence, there are now significant performance gains to be had by using a CallableStatement object instead of a Statement object, if a short-running CALL statement is to be executed more than a small number of times. Moreover, the recent work lays the foundation for work in a subsequenct release to support CallableStatement OUT and IN OUT style parameters, as well as the generation and retrieval of multiple results in response to the execution of a CallableStatement object.

                For a more in-depth discussion of performance issues regarding 1.7.2 prepared and callable statement objects, please see overview section of jdbcPreparedStatment.

                As with many DBMS, HSQLDB support for stored procedures is not provided in a completely standard fashion.

                Beyond the XOpen/ODBC extended scalar functions, stored procedures are typically supported in ways that vary greatly from one DBMS implementation to the next. So, it is almost guaranteed that the code for a stored procedure written under a specific DBMS product will not work without at least some modification in the context of another vendor's product or even across a single vendor's product lines. Moving stored procedures from one DBMS product line to another almost invariably involves complex porting issues and often may not be possible at all. Be warned.

                At present, HSQLDB stored procedures map directly onto the methods of compiled Java classes found on the classpath of the engine at runtime. This is done in a non-standard but fairly efficient way by issuing a class grant (and possibly method aliases) of the form: 

                 GRANT ALL ON CLASS "package.class" TO [<user-name> | PUBLIC]
 CREATE ALIAS <call-alias> FOR "package.class.method" -- optional
                This has the effect of allowing the specified user(s) to access the set of uniquely named public static methods of the specified class, in either the role of SQL functions or stored procedures. For example: 

                 CONNECT <admin-user> PASSWORD <admin-user-password>;
 GRANT ALL ON CLASS "org.myorg.MyClass" TO PUBLIC;
 CREATE ALIAS sp_my_method FOR "org.myorg.MyClass.myMethod"
 CONNECT <any-user> PASSWORD <any-user-password>;
 SELECT "org.myorg.MyClass.myMethod"(column_1) FROM table_1;
 SELECT sp_my_method(column_1) FROM table_1;
 CALL 2 + "org.myorg.MyClass.myMethod"(-5);
 CALL 2 + sp_my_method(-5);
                Please note the use of the term "uniquely named" above. Including 1.7.2, no support is provided to deterministically resolve overloaded method names, and there can be issues with inherited methods as well; currently, it is strongly recommended that developers creating stored procedure library classes for HSQLDB simply avoid designs such that SQL stored procedure calls attempt to resolve to:

                1. inherited public static methods
                2. overloaded public static methods
                Also, please note that OUT and IN OUT parameters are not yet supported due to some unresolved low level support issues.

                Including 1.7.2, the HSQLDB stored procedure call mechanism is essentially a thin wrap of the HSQLDB SQL function call mechanism, extended to include the more general HSQLDB SQL expression evaluation mechanism. In addition to stored procedure calls that resolve directly to Java method invocations, the extention provides the ability to evaluate simple SQL expressions, possibly containing Java method invocations, outside any INSERT, UPDATE, DELETE or SELECT statement context.

                With HSQLDB, executing a CALL statement that produces an opaque (OTHER) or known scalar object reference has virtually the same effect as: 

                 CREATE TABLE DUAL (dummy VARCHAR);
 INSERT INTO DUAL VALUES(NULL);
 SELECT <simple-expression> FROM DUAL;
                As a transitional measure, HSQLDB provides the ability to materialize a general result set in response to stored procedure execution. In this case, the stored procedure's Java method descriptor must specify a return type of java.lang.Object for external use (although at any point in the devlopment cycle, other, proprietary return types may accepted internally for engine development purposes). When HSQLDB detects that the runtime class of the resulting Object is elligible, an automatic internal unwrapping is performed to correctly expose the underlying result set to the client, whether local or remote.

                Additionally, HSQLDB automatically detects if java.sql.Connection is the class of the first argument of any underlying Java method(s). If so, then the engine transparently supplies the internal Connection object corresponding to the Session executing the call, adjusting the positions of other arguments to suite the SQL context.

                The features above are not intended to be permanent. Rather, the intention is to offer more general and powerful mechanisms in a future release; it is recommend to use them only as a temporary convenience.

                For instance, one might be well advised to future-proof by writing HSQLDB-specific adapter methods that in turn call the real logic of an underlying generalized JDBC stored procedure library.

                Here is a very simple example of an HSQLDB stored procedure generating a user-defined result set: 

                 package mypackage;

 class MyClass {

      public static Object mySp(Connection conn) throws SQLException {
          return conn.createStatement().executeQuery("select * from my_table");
      }
 }
                Here is a refinement demonstrating no more than the bare essence of the idea behind a more portable style: 
                 package mypackage;

 import java.sql.ResultSet;
 import java.sql.SQLException;

 class MyLibraryClass {

      public static ResultSet mySp() throws SQLException {
          return ctx.getConnection().createStatement().executeQuery("select * from my_table");
      }
 }

 //--

 package myadaptorpackage;

 import java.sql.Connection;
 import java.sql.SQLException;

 class MyAdaptorClass {

      public static Object mySp(Connection conn) throws SQLException {
          MyLibraryClass.getCtx().setConnection(conn);
          return MyLibraryClass.mySp();
      }
 }
                In a future release, it is intended to provided some new features that will support writing fairly portable JDBC-based stored procedure code:

                • Support for the "jdbc:default:connection" standard database connection url.

                • A well-defined specification of the behaviour of the HSQLDB execution stack under stored procedure calls.

                • A well-defined, pure JDBC specification for generating multiple results from HSQLDB stored procedures for client retrieval.

                          throws java.sql.SQLException
                Registers the OUT parameter in ordinal position parameterIndex to the JDBC type sqlType. All OUT parameters must be registered before a stored procedure is executed.

                The JDBC type specified by sqlType for an OUT parameter determines the Java type that must be used in the get method to read the value of that parameter.

                If the JDBC type expected to be returned to this output parameter is specific to this particular database, sqlType should be java.sql.Types.OTHER. The method getObject(int) retrieves the value.

                Registers the designated output parameter. This version of the method registerOutParameter should be used for a user-defined or REF output parameter. Examples of user-defined types include: STRUCT, DISTINCT, JAVA_OBJECT, and named array types.

                (JDBC4 claraification:) All OUT parameters must be registered before a stored procedure is executed.

                For a user-defined parameter, the fully-qualified SQL type name of the parameter should also be given, while a REF parameter requires that the fully-qualified type name of the referenced type be given. A JDBC driver that does not need the type code and type name information may ignore it. To be portable, however, applications should always provide these values for user-defined and REF parameters. Although it is intended for user-defined and REF parameters, this method may be used to register a parameter of any JDBC type. If the parameter does not have a user-defined or REF type, the typeName parameter is ignored.

                Note: When reading the value of an out parameter, you must use the getter method whose Java type corresponds to the parameter's registered SQL type.

               throws java.sql.SQLException
                Sets the value of the designated parameter with the given object. The second argument must be an object type; for integral values, the java.lang equivalent objects should be used.

                The given Java object will be converted to the given targetSqlType before being sent to the database. If the object has a custom mapping (is of a class implementing the interface SQLData), the JDBC driver should call the method SQLData.writeSQL to write it to the SQL data stream. If, on the other hand, the object is of a class implementing Ref, Blob, Clob, Struct, or Array, the driver should pass it to the database as a value of the corresponding SQL type.

                Note that this method may be used to pass datatabase- specific abstract data types.

                parameterName - the name of the parameter
                x - the object containing the input parameter value
                targetSqlType - the SQL type (as defined in java.sql.Types) to be sent to the database. The scale argument may further qualify this type.
                scale - for java.sql.Types.DECIMAL or java.sql.Types.NUMERIC types, this is the number of digits after the decimal point. For all other types, this value will be ignored.
                Throws:

               throws java.sql.SQLException
                Sets the value of the designated parameter with the given object. The second parameter must be of type Object; therefore, the java.lang equivalent objects should be used for built-in types.

                The JDBC specification specifies a standard mapping from Java Object types to SQL types. The given argument will be converted to the corresponding SQL type before being sent to the database.

                Note that this method may be used to pass datatabase- specific abstract data types, by using a driver-specific Java type. If the object is of a class implementing the interface SQLData, the JDBC driver should call the method SQLData.writeSQL to write it to the SQL data stream. If, on the other hand, the object is of a class implementing Ref, Blob, Clob, Struct, or Array, the driver should pass it to the database as a value of the corresponding SQL type.

                This method throws an exception if there is an ambiguity, for example, if the object is of a class implementing more than one of the interfaces named above.

                         java.util.Calendar cal)
                  throws java.sql.SQLException
                Sets the designated parameter to the given java.sql.Timestamp value, using the given Calendar object. The driver uses the Calendar object to construct an SQL TIMESTAMP value, which the driver then sends to the database. With a Calendar object, the driver can calculate the timestamp taking into account a custom timezone. If no Calendar object is specified, the driver uses the default timezone, which is that of the virtual machine running the application.

             throws java.sql.SQLException
                Sets the designated parameter to SQL NULL. This version of the method setNull should be used for user-defined types and REF type parameters. Examples of user-defined types include: STRUCT, DISTINCT, JAVA_OBJECT, and named array types.

                Note: To be portable, applications must give the SQL type code and the fully-qualified SQL type name when specifying a NULL user-defined or REF parameter. In the case of a user-defined type the name is the type name of the parameter itself. For a REF parameter, the name is the type name of the referenced type. If a JDBC driver does not need the type code or type name information, it may ignore it. Although it is intended for user-defined and Ref parameters, this method may be used to set a null parameter of any JDBC type. If the parameter does not have a user-defined or REF type, the given typeName is ignored.

                Class jdbcDataSource

                java.lang.Object
  extended byorg.hsqldb.jdbc.jdbcDataSource
                All Implemented Interfaces:
                javax.sql.DataSource, javax.naming.Referenceable, java.io.Serializable
                public class jdbcDataSource
                extends java.lang.Object
                implements java.io.Serializable, javax.naming.Referenceable, javax.sql.DataSource

                A factory for connections to the physical data source that this DataSource object represents. An alternative to the DriverManager facility, a DataSource object is the preferred means of getting a connection. An object that implements the DataSource interface will typically be registered with a naming service based on the JavaTM Naming and Directory (JNDI) API.

                The DataSource interface is implemented by a driver vendor. There are three types of implementations:

                1. Basic implementation -- produces a standard Connection object
                2. Connection pooling implementation -- produces a Connection object that will automatically participate in connection pooling. This implementation works with a middle-tier connection pooling manager.
                3. Distributed transaction implementation -- produces a Connection object that may be used for distributed transactions and almost always participates in connection pooling. This implementation works with a middle-tier transaction manager and almost always with a connection pooling manager.

                A DataSource object has properties that can be modified when necessary. For example, if the data source is moved to a different server, the property for the server can be changed. The benefit is that because the data source's properties can be changed, any code accessing that data source does not need to be changed.

                A driver that is accessed via a DataSource object does not register itself with the DriverManager. Rather, a DataSource object is retrieved though a lookup operation and then used to create a Connection object. With a basic implementation, the connection obtained through a DataSource object is identical to a connection obtained through the DriverManager facility.

                The representation of a savepoint, which is a point within the current transaction that can be referenced from the Connection.rollback method. When a transaction is rolled back to a savepoint all changes made after that savepoint are undone.

                Savepoints can be either named or unnamed. Unnamed savepoints are identified by an ID generated by the underlying data source.

                HSQLDB-Specific Information:

                As the SQL 2003 standard does not provide for unnamed savepoints, this feature is not supported.

                If the connection is autoCommit, setting savepoints has no effect as any such savepoint is cleared upon the execution of the first transactional statement.

                Since:

                org.hsqldb.jdbc
                Class jdbcConnection

                java.lang.Object
  extended byorg.hsqldb.jdbc.jdbcConnection
                All Implemented Interfaces:
                java.sql.Connection
                public class jdbcConnection
                extends java.lang.Object
                implements java.sql.Connection

                A connection (session) with a specific database. Within the context of a Connection, SQL statements are executed and results are returned.

                A Connection's database is able to provide information describing its tables, its supported SQL grammar, its stored procedures, the capabilities of this connection, and so on. This information is obtained with the getMetaData method.

                Note: By default the Connection automatically commits changes after executing each statement. If auto commit has been disabled, an explicit commit must be done or database changes will not be saved.

                HSQLDB-Specific Information:

                To get a Connection to an HSQLDB database, the following code may be used (updated to reflect the most recent recommendations):

                When using HSQLDB, the database connection <url> must start with 'jdbc:hsqldb:'

                Since 1.7.2, connection properties (<key-value-pairs>) may be appended to the database connection <url>, using the form:

                '<url>[;key=value]*'

                Also since 1.7.2, the allowable forms of the HSQLDB database connection <url> have been extended. However, all legacy forms continue to work, with unchanged semantics. The extensions are as described in the following material.

                Network Server Database Connections:

                The 1.7.2 Server database connection <url> has changed to take one of the two following forms:

                1. 'jdbc:hsqldb:hsql://host[:port][/<alias>][<key-value-pairs>]'
                2. 'jdbc:hsqldb:hsqls://host[:port][/<alias>][<key-value-pairs>]' (with TLS).

                The 1.7.2 WebServer database connection <url> also changes to take one of two following forms:

                1. 'jdbc:hsqldb:http://host[:port][/<alias>][<key-value-pairs>]'
                2. 'jdbc:hsqldb:https://host[:port][/<alias>][<key-value-pairs>]' (with TLS).

                In both network server database connection <url> forms, the optional <alias> component is used to identify one of possibly several database instances available at the indicated host and port. If the <alias> component is omitted, then a connection is made to the network server's default database instance.

                For more information on server configuration regarding mounting multiple databases and assigning them <alias> values, please read the Java API documentation for Server and related chapters in the general documentation, especially the Advanced Users Guide.

                Transient, In-Process Database Connections:

                The 1.7.2 100% in-memory (transient, in-process) database connection <url> takes one of the two following forms:

                1. 'jdbc:hsqldb:.[<key-value-pairs>]' (the legacy form, extended)
                2. 'jdbc:hsqldb:mem:<alias>[<key-value-pairs>]' (the new form)

                With the 1.7.2 transient, in-process database connection <url>, the <alias> component is the key used to look up a transient, in-process database instance amongst the collection of all such instances already in existence within the current class loading context in the current JVM. If no such instance exists, one may be automatically created and mapped to the <alias>, as governed by the 'ifexists=true|false' connection property.

                Persistent, In-Process Database Connections:

                The 1.7.2 standalone (persistent, in-process) database connection <url> takes one of the three following forms:

                1. 'jdbc:hsqldb:<path>[<key-value-pairs>]' (the legacy form, extended)
                2. 'jdbc:hsqldb:file:<path>[<key-value-pairs>]' (same semantics as the legacy form)
                3. 'jdbc:hsqldb:res:<path>[<key-value-pairs>]' (new form with 'files_in_jar' semantics)

                For the persistent, in-process database connection <url>, the <path> component is the path prefix common to all of the files that compose the database.

                As of 1.7.2, although other files may be involved (such as transient working files and/or TEXT table CSV data source files), the essential set that may, at any particular point in time, compose an HSQLDB database are:

                • <path>.properties
                • <path>.script
                • <path>.log
                • <path>.data
                • <path>.backup
                • <path>.lck

                For example: 'jdbc:hsqldb:file:test' connects to a database composed of some subset of the files listed above, where the expansion of <path> is 'test' prefixed with the path of the working directory fixed at the time the JVM is started.

                Under Windows TM , 'jdbc:hsqldb:file:c:\databases\test' connects to a database located on drive 'C:' in the directory 'databases', composed of some subset of the files: 

                 C:\
 +--databases\
    +--test.properties
    +--test.script
    +--test.log
    +--test.data
    +--test.backup
    +--test.lck
                Under most variations of UNIX, 'jdbc:hsqldb:file:/databases/test' connects to a database located in the directory 'databases' directly under root, once again composed of some subset of the files: 

                 /
 +--databases/
    +--test.properties
    +--test.script
    +--test.log
    +--test.data
    +--test.backup

                Some Guidelines:

                1. Both relative and absolute database file paths are supported.

                2. Relative database file paths can be specified in a platform independent manner as: '[dir1/dir2/.../dirn/]<file-name-prefix>'.

                3. Specification of absolute file paths is operating-system specific.
                  Please read your OS file system documentation.

                4. Specification of network mounts may be operating-system specific.
                  Please read your OS file system documentation.

                5. Special care may be needed w.r.t. file path specifications containing whitespace, mixed-case, special characters and/or reserved file names.
                  Please read your OS file system documentation.

                Note: Versions of HSQLDB previous to 1.7.0 did not support creating directories along the file path specified in the persistent, in-process mode database connection <url> form, in the case that they did not already exist. Starting with HSQLDB 1.7.0, directories will be created if they do not already exist., but only if HSQLDB is built under a version of the compiler greater than JDK 1.1.x.

                res: Connections

                The new 'jdbc:hsqldb:res:<path>' database connection <url> has different semantics than the 'jdbc:hsqldb:file:<path>' form. The semantics are similar to those of a 'files_readonly' database, but with some additional points to consider.

                Specifically, the '<path>' component of a res: type database connection <url> is used to obtain resource URL objects and thereby read the database files as resources on the class path. Moreover, the URL objects must point only to resources contained in one or more jars on the class path (must be jar protocol).

                This restriction is enforced to avoid the unfortunate situation in which, because res: database instances do not create a <path>.lck file (they are strictly files-read-only) and because the <path> components of res: and file: database URIs are not checked for file system equivalence, it is possible for the same database files to be accessed concurrently by both file: and res: database instances. That is, without this restriction, it is possible that <path>.data and <path>.properties file content may be written by a file: database instance without the knowlege or cooperation of a res: database instance open on the same files, potentially resulting in unexpected database errors, inconsistent operation and/or data corruption.

                In short, a res: type database connection <url> is designed specifically to connect to a 'files_in_jar' mode database instance, which in turn is designed specifically to operate under Java WebStartTM and Java AppletTMconfigurations, where co-locating the database files in the jars that make up the WebStart application or Applet avoids the need for special security configuration or code signing.

                Note: Since it is difficult and often nearly impossible to determine or control at runtime from where all classes are being loaded or which class loader is doing the loading under 'files_in_jar' semantics, the <path> component of the res: database connection <url> is always taken to be relative to the default package. That is, if the <path> component does not start with '/', then '/' is prepended when obtaining the resource URLs used to read the database files.

                For more information about HSQLDB file structure, various database modes and other attributes such as those controlled through the HSQLDB properties files, please read the general documentation, especially the Advanced Users Guide.

                JRE 1.1.x Notes:

                In general, JDBC 2 support requires Java 1.2 and above, and JDBC3 requires Java 1.4 and above. In HSQLDB, support for methods introduced in different versions of JDBC depends on the JDK version used for compiling and building HSQLDB.

                Since 1.7.0, it is possible to build the product so that all JDBC 2 methods can be called while executing under the version 1.1.x Java Runtime EnvironmentTM. However, in addition to this technique requiring explicit casts to the org.hsqldb.jdbcXXX classes, some of the method calls also require int values that are defined only in the JDBC 2 or greater version of ResultSet interface. For this reason, when the product is compiled under JDK 1.1.x, these values are defined in jdbcResultSet.

                In a JRE 1.1.x environment, calling JDBC 2 methods that take or return the JDBC2-only ResultSet values can be achieved by referring to them in parameter specifications and return value comparisons, respectively, as follows: 

                 jdbcResultSet.FETCH_FORWARD
 jdbcResultSet.TYPE_FORWARD_ONLY
 jdbcResultSet.TYPE_SCROLL_INSENSITIVE
 jdbcResultSet.CONCUR_READ_ONLY
 // etc.
                However, please note that code written to use HSQLDB JDBC 2 features under JDK 1.1.x will not be compatible for use with other JDBC 2 drivers. Please also note that this feature is offered solely as a convenience to developers who must work under JDK 1.1.x due to operating constraints, yet wish to use some of the more advanced features available under the JDBC 2 specification.

                Constructor Detail

                jdbcConnection

                public jdbcConnection(org.hsqldb.persist.HsqlProperties props)
               throws java.sql.SQLException
                Constructs a new external Connection to an HSQLDB Database.

                This constructor is called on behalf of the java.sql.DriverManager when getting a Connection for use in normal (external) client code.

                Internal client code, that being code located in HSQLDB SQL functions and stored procedures, receives an INTERNAL connection constructed by the jdbcConnection(Session) constructor.

                Parameters:
                props - A Properties object containing the connection properties
                Throws:
                java.sql.SQLException - when the user/password combination is invalid, the connection url is invalid, or the Database is unavailable.

                The Database may be unavailable for a number of reasons, including network problems or the fact that it may already be in use by another process.

                jdbcConnection

                public jdbcConnection(org.hsqldb.Session c)
               throws org.hsqldb.HsqlException
                Constructs an INTERNAL Connection, using the specified Session.

                This constructor is called only on behalf of an existing Session (the internal parallel of a Connection), to be used as a parameter to a SQL function or stored procedure that needs to execute in the context of that Session.

                When a Java SQL function or stored procedure is called and its first parameter is of type Connection, HSQLDB automatically notices this and constructs an INTERNAL Connection using the current Session. HSQLDB then passes this Connection in the first parameter position, moving any other parameter values specified in the SQL statement to the right by one position.

                To read more about this, see Function#getValue().

                Notes:

                Starting with HSQLDB 1.7.2, INTERNAL connections are not closed by a call to close() or by a SQL DISCONNECT. For HSQLDB developers not involved with writing database internals, this change only applies to connections obtained automatically from the database as the first parameter to stored procedures and SQL functions. This is mainly an issue to developers writing custom SQL function and stored procedure libraries for HSQLDB. Presently, it is recommended that SQL function and stored procedure code avoid depending on closing or issuing a DISCONNECT on a connection obtained in this manner.

                Parameters:
                c - the Session requesting the construction of this Connection
                Throws:
                org.hsqldb.HsqlException - never (reserved for future use);

                Method Detail

                createStatement

                public java.sql.Statement createStatement()
                                   throws java.sql.SQLException
                Creates a Statement object for sending SQL statements to the database. SQL statements without parameters are normally executed using Statement objects. If the same SQL statement is executed many times, it may be more efficient to use a PreparedStatement object.

                Result sets created using the returned Statement object will by default be type TYPE_FORWARD_ONLY and have a concurrency level of CONCUR_READ_ONLY.

                HSQLDB-Specific Information:

                Starting with HSQLDB 1.7.2, support for precompilation at the engine level has been implemented, so it is now much more efficient and performant to use a PreparedStatement object if the same SQL statement is executed many times.

                Up to 1.6.1, HSQLDB supported TYPE_FORWARD_ONLY - CONCUR_READ_ONLY results only, so ResultSet objects created using the returned Statement object would always be type TYPE_FORWARD_ONLY with CONCUR_READ_ONLY concurrency.

                Starting with 1.7.0, HSQLDB also supports TYPE_SCROLL_INSENSITIVE results.

                Notes:

                Up to 1.6.1, calling this method returned null if the connection was already closed. This was possibly counter-intuitive to the expectation that an exception would be thrown for closed connections. Starting with 1.7.0. the behaviour is to throw a SQLException if the connection is closed.

                Specified by:
                createStatement in interface java.sql.Connection
                Returns:
                a new default Statement object
                Throws:
                java.sql.SQLException - if a database access error occurs

                prepareStatement

                public java.sql.PreparedStatement prepareStatement(java.lang.String sql)
                                            throws java.sql.SQLException
                Creates a PreparedStatement object for sending parameterized SQL statements to the database.

                A SQL statement with or without IN parameters can be pre-compiled and stored in a PreparedStatement object. This object can then be used to efficiently execute this statement multiple times.

                Note: This method is optimized for handling parametric SQL statements that benefit from precompilation. If the driver supports precompilation, the method prepareStatement will send the statement to the database for precompilation. Some drivers may not support precompilation. In this case, the statement may not be sent to the database until the PreparedStatement object is executed. This has no direct effect on users; however, it does affect which methods throw certain SQLException objects.

                Result sets created using the returned PreparedStatement object will by default be type TYPE_FORWARD_ONLY and have a concurrency level of CONCUR_READ_ONLY.

                HSQLDB-Specific Information:

                Starting with HSQLDB 1.7.2, support for precompilation at the engine level has been implemented, so it is now much more efficient and performant to use a PreparedStatement object if the same SQL statement is executed many times.

                Starting with 1.7.2, the support for and behaviour of PreparedStatment has changed. Please read the introductory section of the documentation for org.hsqldb.jdbc.jdbcPreparedStatement.

                Specified by:
                prepareStatement in interface java.sql.Connection
                Parameters:
                sql - an SQL statement that may contain one or more '?' IN parameter placeholders
                Returns:
                a new default PreparedStatement object containing the pre-compiled SQL statement
                Throws:
                java.sql.SQLException - if a database access error occurs

                See Also:

                prepareCall

                public java.sql.CallableStatement prepareCall(java.lang.String sql)
                                       throws java.sql.SQLException
                Creates a CallableStatement object for calling database stored procedures. The CallableStatement object provides methods for setting up its IN and OUT parameters, and methods for executing the call to a stored procedure.

                Note: This method is optimized for handling stored procedure call statements. Some drivers may send the call statement to the database when the method prepareCall is done; others may wait until the CallableStatement object is executed. This has no direct effect on users; however, it does affect which method throws certain SQLExceptions.

                Result sets created using the returned CallableStatement object will by default be type TYPE_FORWARD_ONLY and have a concurrency level of CONCUR_READ_ONLY.

                HSQLDB-Specific Information:

                Starting with 1.7.2, the support for and behaviour of CallableStatement has changed. Please read the introductory section of the documentation for org.hsqldb.jdbc.jdbcCallableStatement.

                Specified by:
                prepareCall in interface java.sql.Connection
                Parameters:
                sql - a String object that is the SQL statement to be sent to the database; may contain one or more ? parameters.

                Note: Typically the SQL statement is a JDBC function call escape string.

                Returns:
                a new default CallableStatement object containing the pre-compiled SQL statement
                Throws:
                java.sql.SQLException - if a database access error occurs

                nativeSQL

                public java.lang.String nativeSQL(java.lang.String sql)
                           throws java.sql.SQLException
                Converts the given SQL statement into the system's native SQL grammar. A driver may convert the JDBC SQL grammar into its system's native SQL grammar prior to sending it. This method returns the native form of the statement that the driver would have sent.

                HSQLDB-Specific Information:

                Up to and including 1.7.2, HSQLDB converts the JDBC SQL grammar into the system's native SQL grammar prior to sending it, if escape processing is set true; this method returns the native form of the statement that the driver would send in place of client-specified JDBC SQL grammar.

                Before 1.7.2, escape processing was incomplete and also broken in terms of support for nested escapes.

                Starting with 1.7.2, escape processing is complete and handles nesting to arbitrary depth, but enforces a very strict interpretation of the syntax and does not detect or process SQL comments.

                In essence, the HSQLDB engine directly handles the prescribed syntax and date / time formats specified internal to the JDBC escapes. It also directly offers the XOpen / ODBC extended scalar functions specified available internal to the {fn ...} JDBC escape. As such, the driver simply removes the curly braces and JDBC escape codes in the simplest and fastest fashion possible, by replacing them with whitespace. But to avoid a great deal of complexity, certain forms of input whitespace are currently not recognised. For instance, the driver handles "{?= call ...}" but not "{ ?= call ...} or "{? = call ...}"

                Also, comments embedded in SQL are currently not detected or processed and thus may have unexpected effects on the output of this method, for instance causing otherwise valid SQL to become invalid. It is especially important to be aware of this because escape processing is set true by default for Statement objects and is always set true when producing a PreparedStatement from prepareStatement() or CallableStatement from prepareCall(). Currently, it is simply recommended to avoid submitting SQL having comments containing JDBC escape sequence patterns and/or single or double quotation marks, as this will avoid any potential problems. It is intended to implement a less strict handling of whitespace and proper processing of SQL comments at some point in the near future, perhaps before the final 1.7.2 release. In any event, 1.7.2 now correctly processes the following JDBC escape forms to arbitrary nesting depth, but only if the exact whitespace layout described below is used:

                1. {call ...}
                2. {?= call ...}
                3. {fn ...}
                4. {oj ...}
                5. {d ...}
                6. {t ...}
                7. {ts ...}

                Parameters:
                sql - a SQL statement that may contain one or more '?' parameter placeholders
                Returns:
                the native form of this statement

                setAutoCommit

                public void setAutoCommit(boolean autoCommit)
                   throws java.sql.SQLException
                Sets this connection's auto-commit mode to the given state. If a connection is in auto-commit mode, then all its SQL statements will be executed and committed as individual transactions. Otherwise, its SQL statements are grouped into transactions that are terminated by a call to either the method commit or the method rollback. By default, new connections are in auto-commit mode.

                The commit occurs when the statement completes or the next execute occurs, whichever comes first. In the case of statements returning a ResultSet object, the statement completes when the last row of the ResultSet object has been retrieved or the ResultSet object has been closed. In advanced cases, a single statement may return multiple results as well as output parameter values. In these cases, the commit occurs when all results and output parameter values have been retrieved.

                NOTE: If this method is called during a transaction, the transaction is committed.

                Up to and including HSQLDB 1.7.2,

                1. All rows of a result set are retrieved internally before the first row can actually be fetched.
                  Therefore, a statement can be considered complete as soon as any XXXStatement.executeXXX method returns.
                2. Multiple result sets and output parameters are not yet supported.

                commit

                public void commit()
            throws java.sql.SQLException
                Makes all changes made since the previous commit/rollback permanent and releases any database locks currently held by the Connection. This method should be used only when auto-commit mode has been disabled.

                HSQLDB-Specific Information:

                Starting with HSQLDB 1.7.2, savepoints are supported both in SQL and via the JDBC interface.

                Using SQL, savepoints may be set, released and used in rollback as follows: 

                 SAVEPOINT <savepoint-name>
 RELEASE SAVEPOINT <savepoint-name>
 ROLLBACK TO SAVEPOINT <savepoint-name>

                Drops all changes made since the previous commit/rollback and releases any database locks currently held by this Connection. This method should be used only when auto- commit has been disabled.

                HSQLDB-Specific Information:

                Starting with HSQLDB 1.7.2, savepoints are fully supported both in SQL and via the JDBC interface.

                Using SQL, savepoints may be set, released and used in rollback as follows:

                close

                public void close()
           throws java.sql.SQLException
                Releases this Connection object's database and JDBC resources immediately instead of waiting for them to be automatically released.

                Calling the method close on a Connection object that is already closed is a no-op.

                Note: A Connection object is automatically closed when it is garbage collected. Certain fatal errors also close a Connection object.

                HSQLDB-Specific Information:

                In 1.7.2, INTERNAL Connection objects are not closable from JDBC client code.

                Specified by:
                close in interface java.sql.Connection

                                      throws java.sql.SQLException
                Gets the metadata regarding this connection's database. A Connection's database is able to provide information describing its tables, its supported SQL grammar, its stored procedures, the capabilities of this connection, and so on. This information is made available through a DatabaseMetaData object.

                HSQLDB-Specific Information:

                JDBC DatabaseMetaData methods returning ResultSet were not implemented fully before 1.7.2. Some of these methods always returned empty result sets. Other methods did not accurately reflect all of the MetaData for the category. Also, some method ignored the filters provided as parameters, returning an unfiltered result each time.

                Also, the majority of methods returning ResultSet threw an SQLException when accessed by a non-admin user.

                Starting with HSQLDB 1.7.2, essentially full database metadata is supported.

                For discussion in greater detail, please follow the link to the overview for jdbcDatabaseMetaData, below.

                Specified by:
                getMetaData in interface java.sql.Connection

                setReadOnly

                public void setReadOnly(boolean readonly)
                 throws java.sql.SQLException
                Puts this connection in read-only mode as a hint to enable database optimizations.

                Note: This method should not be called while in the middle of a transaction.

                HSQLDB-Specific Information:

                Up to and including 1.7.2, HSQLDB will commit the current transaction automatically when this method is called.

                Additionally, HSQLDB provides a way to put a whole database in read-only mode. This is done by manually adding the line 'readonly=true' to the database's .properties file while the database is offline. Upon restart, all connections will be readonly, since the entire database will be readonly. To take a database out of readonly mode, simply take the database offline and remove the line 'readonly=true' from the database's .properties file. Upon restart, the database will be in regular (read-write) mode.

                When a database is put in readonly mode, its files are opened in readonly mode, making it possible to create CD-based readonly databases. To create a CD-based readonly database that has CACHED tables and whose .data file is suspected of being highly fragmented, it is recommended that the database first be SHUTDOWN COMPACTed before copying the database files to CD. This will reduce the space required and may improve access times against the .data file which holds the CACHED table data.

                Starting with 1.7.2, an alternate approach to opimizing the .data file before creating a CD-based readonly database is to issue the CHECKPOINT DEFRAG command followed by SHUTDOWN to take the database offline in preparation to burn the database files to CD.

                public void setCatalog(java.lang.String catalog)
                throws java.sql.SQLException
                Sets a catalog name in order to select a subspace of this Connection's database in which to work.

                HSQLDB-Specific Information:

                HSQLDB does not yet support catalogs and simply ignores this request.

                Specified by:
                setCatalog in interface java.sql.Connection
                Parameters:
                catalog - the name of a catalog (subspace in this Connection object's database) in which to work (Ignored)

                            throws java.sql.SQLException
                Returns the Connection's current catalog name.

                HSQLDB-Specific Information:

                HSQLDB does not yet support catalogs and always returns null.

                Specified by:
                getCatalog in interface java.sql.Connection
                Returns:

                public void setTransactionIsolation(int level)
                             throws java.sql.SQLException
                Attempts to change the transaction isolation level for this Connection object to the one given. The constants defined in the interface Connection are the possible transaction isolation levels.

                Note: If this method is called during a transaction, the result is implementation-defined.

                Specified by:
                setTransactionIsolation in interface java.sql.Connection
                Parameters:
                level - one of the following Connection constants: Connection.TRANSACTION_READ_UNCOMMITTED , Connection.TRANSACTION_READ_COMMITTED, Connection.TRANSACTION_REPEATABLE_READ, or Connection.TRANSACTION_SERIALIZABLE. (Note that Connection.TRANSACTION_NONE cannot be used because it specifies that transactions are not supported.)
                Throws:
                java.sql.SQLException - if a database access error occurs or the given parameter is not one of the Connection constants

                            throws java.sql.SQLException
                Retrieves this Connection object's current transaction isolation level.

                HSQLDB-Specific Information:

                HSQLDB always returns Connection.TRANSACTION_READ_UNCOMMITED.

                Specified by:
                getTransactionIsolation in interface java.sql.Connection
                Returns:
                the current transaction isolation level, which will be one of the following constants: Connection.TRANSACTION_READ_UNCOMMITTED , Connection.TRANSACTION_READ_COMMITTED, Connection.TRANSACTION_REPEATABLE_READ, Connection.TRANSACTION_SERIALIZABLE, or Connection.TRANSACTION_NONE

                Up to and including 1.7.1, TRANSACTION_READ_UNCOMMITTED is always returned

                Throws:
                java.sql.SQLException - if a database access error occurs

                                throws java.sql.SQLException
                Retrieves the first warning reported by calls on this Connection object. If there is more than one warning, subsequent warnings will be chained to the first one and can be retrieved by calling the method SQLWarning.getNextWarning on the warning that was retrieved previously.

                This method may not be called on a closed connection; doing so will cause an SQLException to be thrown.

                Note: Subsequent warnings will be chained to this SQLWarning.

                HSQLDB-Specific Information:

                Starting with 1.7.2, HSQLDB produces warnings whenever a createStatement(), prepareStatement() or prepareCall() invocation requests an unsupported but defined combination of result set type, concurrency and holdability, such that another set is substituted.

                Specified by:
                getWarnings in interface java.sql.Connection
                Returns:
                the first SQLWarning object or null if there are none

                Throws:
                java.sql.SQLException - if a database access error occurs or this method is called on a closed connection

                   throws java.sql.SQLException
                Clears all warnings reported for this Connection object. After a call to this method, the method getWarnings returns null until a new warning is reported for this Connection.

                HSQLDB-Specific Information:

                Before HSQLDB 1.7.2, SQLWarning was not supported, and calls to this method are simply ignored.

                Starting with HSQLDB 1.7.2, the standard behaviour is implemented.

                Specified by:
                clearWarnings in interface java.sql.Connection

                                   throws java.sql.SQLException
                Creates a Statement object that will generate ResultSet objects with the given type and concurrency. This method is the same as the createStatement method above, but it allows the default result set type and result set concurrency type to be overridden.

                HSQLDB-Specific Information:

                Up to HSQLDB 1.6.1, support was provided only for type TYPE_FORWARD_ONLY and concurrency CONCUR_READ_ONLY.

                Starting with HSQLDB 1.7.0, support is now provided for types TYPE_FORWARD_ONLY, and TYPE_SCROLL_INSENSITIVE, with concurrency CONCUR_READ_ONLY. Starting with HSQLDB 1.7.2, the behaviour regarding the type and concurrency values has changed to more closely conform to the specification. That is, if an unsupported combination is requested, a SQLWarning is issued on this Connection and the closest supported combination is used instead.

                Notes:

                Up to 1.6.1, calling this method returned null if the connection was already closed and a supported combination of type and concurrency was specified. This was possibly counter-intuitive to the expectation that an exception would be thrown for closed connections. Starting with 1.7.0. the behaviour is to throw a SQLException if the connection is closed.

                Specified by:
                createStatement in interface java.sql.Connection
                Parameters:

                concurrency - a concurrency type; one of ResultSet.CONCUR_READ_ONLY or ResultSet.CONCUR_UPDATABLE (not supported)
                Returns:
                a new Statement object that will, within the release-specific documented limitations of support, generate ResultSet objects with the given type and concurrency
                Throws:
                java.sql.SQLException - if a database access error occurs or the given parameters are not ResultSet constants indicating a supported type and concurrency

                Creates a PreparedStatement object that will generate ResultSet objects with the given type and concurrency. This method is the same as the prepareStatement method above, but it allows the default result set type and result set concurrency type to be overridden.

                HSQLDB-Specific Information:

                Starting with HSQLDB 1.7.2, the behaviour regarding the type and concurrency values has changed to more closely conform to the specification. That is, if an unsupported combination is requested, a SQLWarning is issued on this Connection and the closest supported combination is used instead.

                Also starting with 1.7.2, the support for and behaviour of PreparedStatment has changed. Please read the introductory section of the documentation for org.hsqldb.jdbc.jdbcPreparedStatement.

                                       throws java.sql.SQLException
                Creates a CallableStatement object that will generate ResultSet objects with the given type and concurrency. This method is the same as the prepareCall method above, but it allows the default result set type and result set concurrency type to be overridden.

                HSQLDB-Specific Information:

                Starting with HSQLDB 1.7.2, the behaviour regarding the type, concurrency and holdability values has changed to more closely conform to the specification. That is, if an unsupported combination is requrested, a SQLWarning is issued on this Connection and the closest supported combination is used instead.

                Also starting with 1.7.2, the support for and behaviour of CallableStatement has changed. Please read the introdutory section of the documentation for org.hsqldb.jdbc.jdbcCallableStatement.

                Creates a default PreparedStatement object that has the capability to retrieve auto-generated keys. The given constant tells the driver whether it should make auto-generated keys available for retrieval. This parameter is ignored if the SQL statement is not an INSERT statement.

                Note: This method is optimized for handling parametric SQL statements that benefit from precompilation. If the driver supports precompilation, the method prepareStatement will send the statement to the database for precompilation. Some drivers may not support precompilation. In this case, the statement may not be sent to the database until the PreparedStatement object is executed. This has no direct effect on users; however, it does affect which methods throw certain SQLExceptions.

                Result sets created using the returned PreparedStatement object will by default be type TYPE_FORWARD_ONLY and have a concurrency level of CONCUR_READ_ONLY.

                                                   int[] columnIndexes)
                                            throws java.sql.SQLException
                Creates a default PreparedStatement object capable of returning the auto-generated keys designated by the given array. This array contains the indexes of the columns in the target table that contain the auto-generated keys that should be made available. This array is ignored if the SQL statement is not an INSERT statement.

                An SQL statement with or without IN parameters can be pre-compiled and stored in a PreparedStatement object. This object can then be used to efficiently execute this statement multiple times.

                Note: This method is optimized for handling parametric SQL statements that benefit from precompilation. If the driver supports precompilation, the method prepareStatement will send the statement to the database for precompilation. Some drivers may not support precompilation. In this case, the statement may not be sent to the database until the PreparedStatement object is executed. This has no direct effect on users; however, it does affect which methods throw certain SQLExceptions.

                Result sets created using the returned PreparedStatement object will by default be type TYPE_FORWARD_ONLY and have a concurrency level of CONCUR_READ_ONLY.

                HSQLDB-Specific Information:

                HSQLDB 1.7.2 does not support this feature.

                Calling this method always throws a SQLException, stating that the function is not supported.

                Specified by:
                prepareStatement in interface java.sql.Connection
                Parameters:
                sql - an SQL statement that may contain one or more '?' IN parameter placeholders
                columnIndexes - an array of column indexes indicating the columns that should be returned from the inserted row or rows
                Returns:
                a new PreparedStatement object, containing the pre-compiled statement, that is capable of returning the auto-generated keys designated by the given array of column indexes
                Throws:
                java.sql.SQLException - if a database access error occurs
                Since:

                Class jdbcDatabaseMetaData

                java.lang.Object
  extended byorg.hsqldb.jdbc.jdbcDatabaseMetaData
                All Implemented Interfaces:
                java.sql.DatabaseMetaData
                public class jdbcDatabaseMetaData
                extends java.lang.Object
                implements java.sql.DatabaseMetaData

                Comprehensive information about the database as a whole.

                This interface is implemented by driver vendors to let users know the capabilities of a Database Management System (DBMS) in combination with the driver based on JDBCTM technology ("JDBC driver") that is used with it. Different relational DBMSs often support different features, implement features in different ways, and use different data types. In addition, a driver may implement a feature on top of what the DBMS offers. Information returned by methods in this interface applies to the capabilities of a particular driver and a particular DBMS working together. Note that as used in this documentation, the term "database" is used generically to refer to both the driver and DBMS.

                A user for this interface is commonly a tool that needs to discover how to deal with the underlying DBMS. This is especially true for applications that are intended to be used with more than one DBMS. For example, a tool might use the method getTypeInfo to find out what data types can be used in a CREATE TABLE statement. Or a user might call the method supportsCorrelatedSubqueries to see if it is possible to use a correlated subquery or supportsBatchUpdates to see if it is possible to use batch updates.

                Some DatabaseMetaData methods return lists of information in the form of ResultSet objects. Regular ResultSet methods, such as getString and getInt, can be used to retrieve the data from these ResultSet objects. If a given form of metadata is not available, the ResultSet getter methods throw an SQLException.

                Some DatabaseMetaData methods take arguments that are String patterns. These arguments all have names such as fooPattern. Within a pattern String, "%" means match any substring of 0 or more characters, and "_" means match any one character. Only metadata entries matching the search pattern are returned. If a search pattern argument is set to null, that argument's criterion will be dropped from the search.

                A method that gets information about a feature that the driver does not support will throw an SQLException. In the case of methods that return a ResultSet object, either a ResultSet object (which may be empty) is returned or an SQLException is thrown.

                HSQLDB-Specific Information:

                Starting with HSQLDB 1.7.2, an option is provided to allow alternate system table production implementations. In this distribution, there are three implementations whose behaviour ranges from producing no system tables at all to producing a richer and more complete body of information about an HSQLDB database than was previously available. The information provided through the default implementation is, unlike previous versions, accessible to all database users, regardless of admin status. This is now possible because the table content it produces for each user is pre-filtered, based on the user's access rights. That is, each system table now acts like a security-aware View.

                The process of installing a system table production class is transparent and occurs dynamically at runtime during the opening sequence of a Database instance, in the newDatabaseInformation() factory method of the revised DatabaseInformation class, using the following steps:

                1. If a class whose fully qualified name is org.hsqldb.DatabaseInformationFull can be found and it has an accesible constructor that takes an org.hsqldb.Database object as its single parameter, then an instance of that class is reflectively instantiated and is used by the database instance to produce its system tables.

                2. If 1.) fails, then the process is repeated, attempting to create an instance of org.hsqldb.DatabaseInformationMain (which provides just the core set of system tables required to service this class, but now does so in a more security aware and comprehensive fashion).

                3. If 2.) fails, then an instance of org.hsqldb.DatabaseInformation is installed (that, by default, produces no system tables, meaning that calls to all related methods in this class will fail, throwing an SQLException stating that a required system table is not found).

                The process of searching for alternate implementations of database support classes, ending with the installation of a minimal but functional default will be refered to henceforth as graceful degradation. This process is advantageous in that it allows developers and administrators to easily choose packaging options, simply by adding to or deleting concerned classes from an HSQLDB installation, without worry over providing complex initialization properties or disrupting the core operation of the engine. In this particular context, graceful degradation allows easy choices regarding database metadata, spanning the range of full (design-time), custom-written, minimal (production-time) or null (space-constrained) system table production implementations.

                In the default full implementation, a number of new system tables are provided that, although not used directly by this class, present previously unavailable information about the database, such as about its triggers and aliases.

                In order to better support graphical database exploration tools and as an experimental intermediate step toward more fully supporting SQL9n and SQL200n, the default installed DatabaseInformation implementation is also capable of reporting pseudo name space information, such as the catalog (database URI) of database objects.

                The catalog reporting feature is turned off by default but can be turned on by providing the appropriate entries in the database properties file (see the advanced topics section of the product documentation).

                When the feature is turned on, catalog is reported using the following conventions:

                1. All objects are reported as having a catalog equal to the URI of the database, which is equivalent to the catenation of the <type> and <path> portions of the HSQLDB internal JDBC connection URL.

                  Examples: 

                       "jdbc:hsqldb:file:test"      => "file:test"
     "jdbc:hsqldb:mem:."          => "mem:."
     "jdbc:hsqldb:hsql:/host/..." => URI of aliased database
     "jdbc:hsqldb:http:/host/..." => URI of aliased database
                  Note: No provision is made for qualifying database objects by catalog in DML or DDL SQL. This feature is functional only with respect to browsing the database through the DatabaseMetaData and system table interfaces.

                Again, it should be well understood that this feature provide an emulation of catalog support and is intended only as an experimental implementation to enhance the browsing experience when using graphical database explorers and to make a first foray into tackling the issue of implementing true catalog support in the future.

                Due the nature of the new database system table production process, fewer assumptions can be made by this class about what information is made available in the system tables supporting DatabaseMetaData methods. Because of this, the SQL queries behind the ResultSet producing methods have been cleaned up and made to adhere more strictly to the JDBC contracts specified in relation to the method parameters.

                One of the remaining assumptions concerns the approximate argument of getIndexInfo(). This parameter is still ignored since there is not yet any process in place to internally gather and persist table and index statistics. A primitive version of a statistics gathering and reporting subsystem may be introduced some time in the 1.7.x series of releases, but no hard decision has yet been made.

                Another assumption is that simple select queries against certain system tables will return rows in JDBC contract order in the absence of an "ORDER BY" clause. The reason for this is that results come back much faster when no "ORDER BY" clause is used. Developers wishing to extend or replace an existing system table production class should be aware of this, either adding the contract "ORDER BY" clause to the SQL in corresponding methods in this class, or, better, by maintaing rows in the correct order in the underlying system tables, prefereably by creating appropriate primary indices.

                JRE 1.1.x Notes:

                In general, JDBC 2 support requires Java 1.2 and above, and JDBC3 requires Java 1.4 and above. In HSQLDB, support for methods introduced in different versions of JDBC depends on the JDK version used for compiling and building HSQLDB.

                Since 1.7.0, it is possible to build the product so that all JDBC 2 methods can be called while executing under the version 1.1.x Java Runtime EnvironmentTM. However, some of these method calls require int values that are defined only in the JDBC 2 or greater version of the ResultSet interface. For this reason, when the product is compiled under JDK 1.1.x, these values are defined in jdbcResultSet.

                In a JRE 1.1.x environment, calling JDBC 2 methods that take or return the JDBC2-only ResultSet values can be achieved by referring to them in parameter specifications and return value comparisons, respectively, as follows: 

                 jdbcResultSet.FETCH_FORWARD
 jdbcResultSet.TYPE_FORWARD_ONLY
 jdbcResultSet.TYPE_SCROLL_INSENSITIVE
 jdbcResultSet.CONCUR_READ_ONLY
 // etc
                However, please note that code written in such a manner will not be compatible for use with other JDBC 2 drivers, since they expect and use ResultSet, rather than jdbcResultSet. Also note, this feature is offered solely as a convenience to developers who must work under JDK 1.1.x due to operating constraints, yet wish to use some of the more advanced features available under the JDBC 2 specification.

                Retrieves a description of the stored procedures available in the given catalog.

                Only procedure descriptions matching the schema and procedure name criteria are returned. They are ordered by PROCEDURE_SCHEM and PROCEDURE_NAME.

                Each procedure description has the the following columns:

                1. PROCEDURE_CAT String => procedure catalog (may be null)
                2. PROCEDURE_SCHEM String => procedure schema (may be null)

                HSQLDB-Specific Information:

                HSQLDB treats unquoted identifiers as case insensitive in SQL but stores them in upper case; it treats quoted identifiers as case sensitive and stores them verbatim. All jdbcDatabaseMetaData methods perform case-sensitive comparison between name (pattern) arguments and the corresponding identifier values as they are stored in the database. Therefore, care must be taken to specify name arguments precisely (including case) as they are stored in the database.

                Since 1.7.2, this feature is supported by default. If the jar is compiled without org.hsqldb.DatabaseInformationFull or org.hsqldb.DatabaseInformationMain, the feature is not supported. The default implementation is DatabaseInformationFull.

                12. NULLABLE short => can it contain NULL.
                  • procedureNoNulls - does not allow NULL values
                  • procedureNullable - allows NULL values
                  • procedureNullableUnknown - nullability unknown
                13. REMARKS String => comment describing parameter/column

                Note: Some databases may not return the column descriptions for a procedure. Additional columns beyond REMARKS can be defined by the database.

                HSQLDB treats unquoted identifiers as case insensitive in SQL but stores them in upper case; it treats quoted identifiers as case sensitive and stores them verbatim. All jdbcDatabaseMetaData methods perform case-sensitive comparison between name (pattern) arguments and the corresponding identifier values as they are stored in the database. Therefore, care must be taken to specify name arguments precisely (including case) as they are stored in the database.

                Since 1.7.0, HSQLDB returns extra information on TEXT tables in the REMARKS column.

                Since 1.7.0, HSQLDB includes the new JDBC3 columns TYPE_CAT, TYPE_SCHEM, TYPE_NAME and SELF_REFERENCING_COL_NAME in anticipation of JDBC3 compliant tools.

                Since 1.7.2, this feature is supported by default. If the jar is compiled without org.hsqldb.DatabaseInformationFull or org.hsqldb.DatabaseInformationMain, the feature is not supported. The default implementation is DatabaseInformationFull.

                HSQLDB-Specific Information:

                HSQLDB treats unquoted identifiers as case insensitive in SQL but stores them in upper case; it treats quoted identifiers as case sensitive and stores them verbatim. All jdbcDatabaseMetaData methods perform case-sensitive comparison between name (pattern) arguments and the corresponding identifier values as they are stored in the database. Therefore, care must be taken to specify name arguments precisely (including case) as they are stored in the database.

                Since 1.7.2, this feature is supported by default. If the jar is compiled without org.hsqldb.DatabaseInformationFull or org.hsqldb.DatabaseInformationMain, the feature is not supported. The default implementation is DatabaseInformationFull.

                table - a table name; must match the table name as it is stored in this database
                unique - when true, return only indices for unique values; when false, return indices regardless of whether unique or not
                approximate - when true, result is allowed to reflect approximate or out of date values; when false, results are requested to be accurate

                HSQLDB-Specific Information:

                HSQLDB treats unquoted identifiers as case insensitive in SQL but stores them in upper case; it treats quoted identifiers as case sensitive and stores them verbatim. All jdbcDatabaseMetaData methods perform case-sensitive comparison between name (pattern) arguments and the corresponding identifier values as they are stored in the database. Therefore, care must be taken to specify name arguments precisely (including case) as they are stored in the database.

                Up to and including 1.7.1, HSQLDB does not support UDTs and thus produces an empty result.

                Starting with 1.7.2, there is an option to support this feature to greater or lesser degrees. See the documentation specific to the selected system table provider implementation. The default implementation is org.hsqldb.DatabaseInformationFull.

                                 throws java.sql.SQLException
                Retrieves a description of the user-defined type (UDT) hierarchies defined in a particular schema in this database. Only the immediate super type sub type relationship is modeled.

                Only supertype information for UDTs matching the catalog, schema, and type name is returned. The type name parameter may be a fully-qualified name. When the UDT name supplied is a fully-qualified name, the catalog and schemaPattern parameters are ignored.

                If a UDT does not have a direct super type, it is not listed here. A row of the ResultSet object returned by this method describes the designated UDT and a direct supertype. A row has the following columns:

                1. TYPE_CAT String => the UDT's catalog (may be null)
                2. TYPE_SCHEM String => UDT's schema (may be null)
                3. TYPE_NAME String => type name of the UDT
                4. SUPERTYPE_CAT String => the direct super type's catalog (may be null)
                5. SUPERTYPE_SCHEM String => the direct super type's schema (may be null)
                6. SUPERTYPE_NAME String => the direct super type's name

                Note: If the driver does not support type hierarchies, an empty result set is returned.

                HSQLDB-Specific Information:

                HSQLDB treats unquoted identifiers as case insensitive in SQL but stores them in upper case; it treats quoted identifiers as case sensitive and stores them verbatim.

Therefore, care must be taken to specify name arguments precisely (including case) as they are stored in the database.

                Including 1.7.1, this JDBC feature is not supported; calling this method throws a SQLException stating that the operation is not supported.

                Since 1.7.2, this feature is supported by default. If the jar is compiled without org.hsqldb.DatabaseInformationFull or org.hsqldb.DatabaseInformationMain, the feature is not supported. The default implementation is DatabaseInformationFull.

                Retrieves a description of the table hierarchies defined in a particular schema in this database.

                Only supertable information for tables matching the catalog, schema and table name are returned. The table name parameter may be a fully- qualified name, in which case, the catalog and schemaPattern parameters are ignored. If a table does not have a super table, it is not listed here. Supertables have to be defined in the same catalog and schema as the sub tables. Therefore, the type description does not need to include this information for the supertable.

                Each type description has the following columns:

                1. TABLE_CAT String => the type's catalog (may be null)
                2. TABLE_SCHEM String => type's schema (may be null)
                3. TABLE_NAME String => type name
                4. SUPERTABLE_NAME String => the direct super type's name

                public class SqlTool
                extends java.lang.Object

                Sql Tool. A command-line and/or interactive SQL tool. (Note: For every Javadoc block comment, I'm using a single blank line immediately after the description, just like's Sun's examples in their Coding Conventions document). See JavaDocs for the main method for syntax of how to run. This class is mostly used in a static (a.o.t. object) way, because most of the work is done in the static main class. This class should be refactored so that the main work is done in an object method, and the static main invokes the object method. Then programmatic users could use instances of this class in the normal Java way.

                main

                public static void main(java.lang.String[] args)
                A static wrapper for objectMain, so that that method may be executed as a Java "program". Throws only RuntimExceptions or Errors, because this method is intended to System.exit() for all but disasterous system problems, for which the inconvenience of a a stack trace would be the least of your worries. If you don't want SqlTool to System.exit(), then use the method objectMain() instead of this method.

                public static void objectMain(java.lang.String[] arg)
                       throws SqlTool.SqlToolException
                Connect to a JDBC Database and execute the commands given on stdin or in SQL file(s). This method is changed for HSQLDB 1.8.0.8 and 1.9.0.x to never System.exit().

                Parameters:
                arg - Run "java... org.hsqldb.util.SqlTool --help" for syntax.
                Throws:
                SqlTool.SqlToolException - Upon any fatal error, with useful reason as the exception's message.

                The method invoked upon each triggered action.

                When UPDATE triggers are fired, oldRow contains the existing values of the table row and newRow contains the new values.

                For INSERT triggers, oldRow is null and newRow contains the table row to be inserted. For DELETE triggers, newRow is null and oldRow contains the table row to be deleted. type contains the integer index id for trigger type, e.g. TriggerDef.INSERT_AFTER (fredt@users)

                Parameters:
                trigName - the name of the trigger
                tabName - the name of the table upon which the triggered action is occuring
                oldRow - the old row
                newRow - the new row

                org.hsqldb
                Class Server

                java.lang.Object
  extended byorg.hsqldb.Server
                All Implemented Interfaces:
                org.hsqldb.HsqlSocketRequestHandler
                Direct Known Subclasses:
                WebServer
                public class Server
                extends java.lang.Object
                implements org.hsqldb.HsqlSocketRequestHandler

                The HSQLDB HSQL protocol network database server.

                A Server object acts as a network database server and is one way of using the client-server mode of HSQLDB Database Engine. Instances of this class handle native HSQL protocol connections exclusively, allowing database queries to be performed efficienly across the network. Server's direct descendent, WebServer, handles HTTP protocol connections exclusively, allowing HSQL protocol to be tunneled over HTTP to avoid sandbox and firewall issues, albeit less efficiently.

                There are a number of ways to configure and start a Server instance.

                When started from the command line or programatically via the main(String[]) method, configuration occurs in three phases, with later phases overriding properties set by previous phases:

                1. Upon construction, a Server object is assigned a set of default properties.

                2. If it exists, properties are loaded from a file named 'server.properties' in the present working directory.

                3. The command line arguments (alternatively, the String[] passed to main()) are parsed and used to further configure the Server's properties.

                From the command line, the options are as follows: 

                 +----------------+-------------+----------+------------------------------+
 |    OPTION      |    TYPE     | DEFAULT  |         DESCRIPTION          |
 +----------------+-------------+----------+------------------------------|
 | -?             | --          | --       | prints this message          |
 | -address       | name|number | any      | server inet address          |
 | -port          | number      | 9001/544 | port at which server listens |
 | -database.i    | [type]spec  | 0=test   | path of database i           |
 | -dbname.i      | alias       | --       | url alias for database i     |
 | -silent        | true|false  | true     | false => display all queries |
 | -trace         | true|false  | false    | display JDBC trace messages  |
 | -tls           | true|false  | false    | TLS/SSL (secure) sockets     |
 | -no_system_exit| true|false  | false    | do not issue System.exit()   |
 | -remote_open   | true|false  | false    | can open databases remotely  |
 +----------------+-------------+----------+------------------------------+
                The database.i and dbname.i options need further explanation:
                • Multiple databases can be served by each instance of the Server. The value of i is currently limited to the range 0..9, allowing up to 10 different databases. Any number is this range can be used.

                • The value assigned to database.i is interpreted using the format '[type]spec', where the optional type component is one of 'file:', 'res:' or 'mem:' and the spec component is interpreted in the context of the type component.

                  If omitted, the type component is taken to be 'file:'.

                  A full description of how '[type]spec' values are interpreted appears in the overview for jdbcConnection.

                • The value assigned to dbname.i is taken to be the key used to look up the desired database instance and thus corresponds to the <alias> component of the HSQLDB HSQL protocol database connection url: 'jdbc:hsqldb:hsql[s]://host[port][/<alias>]'.

                • The value of database.0 is special. If dbname.0 is not specified, then this defaults to an empty string and a connection is made to database.0 path when the <alias> component of an HSQLDB HSQL protocol database connection url is omitted. If a database key/value pair is found in the properties when the main method is called, this pair is supersedes the database.0 setting

                  This behaviour allows the previous database connection url format to work with essentially unchanged semantics.

                • When the remote_open property is true, a connection attempt to an unopened database results in the database being opened. The URL for connection should include the property filepath to specify the path. 'jdbc:hsqldb:hsql[s]://host[port]/<alias>;filepath=hsqldb:file:<database path>'. the given alias and filepath value will be associated together. The database user and password to start this connection must be valid. If this form of connection is used again, after the database has been opened, the filepath property is ignored.

                • Once an alias such as "mydb" has been associated with a path, it cannot be reassigned to a different path.

                • If a database is closed with the SHUTDOWN command, its alias is removed. It is then possible to connect to this database again with a different (or the same) alias.

                • If the same database is connected to via two different aliases, and then one of the is closed with the SHUTDOWN command, the other is also closed.

                From the 'server.properties' file, options can be set similarly, using a slightly different format.

                Here is an example 'server.properties' file: 

                 server.port=9001
 server.database.0=test
 server.dbname.0=...
 ...
 server.database.n=...
 server.dbname.n=...
 server.silent=true
                Starting with 1.7.2, Server has been refactored to become a simple JavaBean with non-blocking start() and stop() service methods. It is possible to configure a Server instance through the JavaBean API as well, but this part of the public interface is still under review and will not be finalized or documented fully until the final 1.7.2 release.

                Note:

                The 'no_system_exit' property is of particular interest.

                If a Server instance is to run embedded in, say, an application server, such as when the jdbcDataSource or HsqlServerFactory classes are used, it is typically necessary to avoid calling System.exit() when the Server instance shuts down.

                By default, 'no_system_exit' is set:

                1. true when a Server is started directly from the start() method.

                2. false when a Server is started from the main(String[]) method.

                These values are natural to their context because the first case allows the JVM to exit by default on Server shutdown when a Server instance is started from a command line environment, whereas the second case prevents a typically unwanted JVM exit on Server shutdown when a Server intance is started as part of a larger framework.

                org.hsqldb.sample
                Class TriggerSample

                java.lang.Object
  extended byorg.hsqldb.sample.TriggerSample
                All Implemented Interfaces:
                Trigger
                public class TriggerSample
                extends java.lang.Object
                implements Trigger

                Sample code for use of triggers in hsqldb. SQL to invoke is:

                CREATE TRIGGER triggerSample BEFORE|AFTER INSERT|UPDATE|DELETE ON myTable [FOR EACH ROW] [QUEUE n] [NOWAIT] CALL "myPackage.trigClass"
                This will create a thread that will wait for its firing event to occur; when this happens, the trigger's thread runs the 'trigClass.fire' Note that this is still in the same Java Virtual Machine as the database, so make sure the fired method does not hang.

                There is a queue of events waiting to be run by each trigger thread. This is particularly useful for 'FOR EACH ROW' triggers, when a large number of trigger events occur in rapid succession, without the trigger thread getting a chance to run. If the queue becomes full, subsequent additions to it cause the database engine to suspend awaiting space in the queue. Take great care to avoid this situation if the trigger action involves accessing the database, as deadlock will occur. This can be avoided either by ensuring the QUEUE parameter makes a large enough queue, or by using the NOWAIT parameter, which causes a new trigger event to overwrite the most recent event in the queue. The default queue size is 1024.

                Ensure that "myPackage.trigClass" is present in the classpath which you use to start hsql.

                If the method wants to access the database, it must establish a JDBC connection.

                When the 'fire' method is called, it is passed the following arguments:

                fire (int type, String trigName, String tabName, Object oldRow[], Object[] newRow)

                where 'type' is one of the values enumerated in the Trigger interface and the 'oldRow'/'newRow' pair represents the rows acted on. The first length - 1 array slots contain column values and the final slot contains either null or the value of the internally assigned row identity, if the concerned table has no primary key. The final slot must _never_ be modified.

                The mapping of row classes to database types is specified in /doc/hsqlSyntax.html#Datatypes.

                To be done:

                1. Implement the "jdbc:default:connection: URL to provide transparent and portable access to internal connections for use in triggers and stored procedures.

                2. Implement declaritive column to trigger method argument mapping, conditional execution (WHEN clause), etc.

                3. Investigate and refine synchronous and asynchronous trigger models.

                  Because certain combinations of trigger create parameters cause the individual triggered actions of a multirow update to run in different threads, it is possible for an 'after' trigger to run before its corresponding 'before' trigger; the acceptability and implications of this needs to be investigated, documented and the behaviour of the engine fully specified.

                4. Investigate and implement the SQL 200n specified execution stack under arbitrary triggered action and SQL-invoked routine call graphs.

                extends Server

                The HSQLDB HTTP protocol network database server.

                WebServer has two distinct functions:

                The primary function is to allow client/server access to HSQLDB databases via the HTTP protocol. This protocol is less efficient than the HSQL protocol used by the Server class and should be used only in situations where sandboxes or firewalls between the client and the server do not allow the use of the HSQL protocol. One example is client/server access by an applet running in browsers on remote hosts and accessing the database engine on the HTTP server from which the applet originated. From version 1.7.2, HTTP database connections are persistent and support transactions. Similar to HSQL connections, they should be explicitly closed to free the server resources.

                The secondary function of WebServer is to act as a simple general purpose HTTP server. It is aimed to support the minimum requirements set out by the HTTP/1.0 standard. The HEAD and GET methods can be used to query and retreive static files from the HTTP server.

                Both the database server and HTTP server functions of WebServer can be configured with the webserver.properties file. It contains entries for the database server similar to those for the HSQL protocol Server class. In addition, a list mapping different file endings to their mime types may be included in this file.

                How This API Document Is Organized

                This API (Application Programming Interface) document has pages corresponding to the items in the navigation bar, described as follows.

                Overview

                The Overview page is the front page of this API document and provides a list of all packages with a summary for each. This page can also contain an overall description of the set of packages.

                Package

                Each package has a page that contains a list of its classes and interfaces, with a summary for each. This page can contain four categories:

                • Interfaces (italic)
                • Classes
                • Exceptions
                • Errors

                Class/Interface

                Each class, interface, nested class and nested interface has its own separate page. Each of these pages has three sections consisting of a class/interface description, summary tables, and detailed member descriptions:

                • Class inheritance diagram
                • Direct Subclasses
                • All Known Subinterfaces
                • All Known Implementing Classes
                • Class/interface declaration
                • Class/interface description

                • Nested Class Summary
                • Field Summary
                • Constructor Summary
                • Method Summary

                • Field Detail
                • Constructor Detail
                • Method Detail
                Each summary entry contains the first sentence from the detailed description for that item. The summary entries are alphabetical, while the detailed descriptions are in the order they appear in the source code. This preserves the logical groupings established by the programmer.

                Use

                Each documented package, class and interface has its own Use page. This page describes what packages, classes, methods, constructors and fields use any part of the given class or package. Given a class or interface A, its Use page includes subclasses of A, fields declared as A, methods that return A, and methods and constructors with parameters of type A. You can access this page by first going to the package, class or interface, then clicking on the "Use" link in the navigation bar.

                Tree (Class Hierarchy)

                There is a Class Hierarchy page for all packages, plus a hierarchy for each package. Each hierarchy page contains a list of classes and a list of interfaces. The classes are organized by inheritance structure starting with java.lang.Object. The interfaces do not inherit from java.lang.Object.
                • When viewing the Overview page, clicking on "Tree" displays the hierarchy for all packages.
                • When viewing a particular package, class or interface page, clicking "Tree" displays the hierarchy for only that package.

                Deprecated API

                The Deprecated API page lists all of the API that have been deprecated. A deprecated API is not recommended for use, generally due to improvements, and a replacement API is usually given. Deprecated APIs may be removed in future implementations.

                Index

                The Index contains an alphabetic list of all classes, interfaces, constructors, methods, and fields.

                Prev/Next

                These links take you to the next or previous class, interface, package, or related page.

                Frames/No Frames

                These links show and hide the HTML frames. All pages are available with or without frames.

                Serialized Form

                Each serializable or externalizable class has a description of its serialization fields and methods. This information is of interest to re-implementors, not to developers using the API. While there is no link in the navigation bar, you can get to this information by going to any serialized class and clicking "Serialized Form" in the "See also" section of the class description.

                This help file applies to API documentation generated using the standard doclet.

A list of changes by subject area is in changelog_1_7_2.txt. Fred Toussi (fredt@users.sourceforge.net) 2004.12.24 UPDATED RELEASE 1.7.2.11 Fixed NPE error when functions in subqueries. Added support for STDDEV_POP, STDDEV_SAMP, VAR_POP, VAR_SAMP, EVERY and SOME set functions. Fixed potential issues with logging DELETE statements for tables with multi-key primary keys. 2004.12.05 UPDATED RELEASE 1.7.2.10 Fixed minor type conversion bugs. Fixed JDK 1.1 compile issue Fixed minor bug relating to server thread startup 2004.11.25 UPDATED RELEASE 1.7.2.8 Fixed bug LIMIT and TOP with UNION Fixed bug running Database Manager as applet Enhancement to allow a table with a label used in DELETE and UPDATE Enhancement to reduce memory use when restoring long log with too many connections Enhancement to persist values set by SET LOGSIZE Minor internal enhancements and refactoring 2004.10.28 UPDATED RELEASE 1.7.2.7 Fixed new bug with TEXT TABLES without primary key 2004.10.25 UPDATED RELEASE 1.7.2.6 Fixed new bug with DATETIME literal default values 2004.10.22 UPDATED RELEASE 1.7.2.5 Fixed bugs OUTER support. Fixed bug that resulted in slowdown when JDBC metadata calls are called many times. Fixed bug related to Statement.setMaxRows(int). The maximum row count will no longer apply to result sets returned and used internally. Fixed bug to allow ResultSetMetaData methods to be used inside stored procedures. Fixed bugs related to some OUTER queries. Performance improvements to some operations on CACHED tables. Improved compatibility with older database files, allowing old style DEFAULT clauses to compile. Improvements to startup after a machine crash. The .log file is now read only until the first malformed line. Corrections to build scripts and #idfef blocks to allow jars to be compiled to run under JDK 1.1. 2004.08.26 UPDATED RELEASE 1.7.2.4 Fixed bug in data file enlargement. Fixed bug where temp tables were removed after another connection closed. 2004.08.12 UPDATED RELEASE 1.7.2.3 Fixed bug preventing the use of hsqldb.files_read_only property Minor enhancements allowing use of SELECT ALL and COUNT(ALL colname) etc. Corrections to the documentation 2004.07.25 UPDATED RELEASE 1.7.2.2 Fixed bug that prevented ALTER TABLE ADD FOREIGH KEY, ADD UNIQUE and ADD CHECK (unnamed constraints) from executing. Fixed excessive logging of SEQUENCE values. 2004.07.20 UPDATED RELEASE 1.7.2.1 Fixed bug where a foreign key with ON DELETE CASCADE action on a table masked other foreign keys on the table and resulted in completion of the cascading action when referential integrity was violated. 2004.07.15 RC_6e INITIAL RELEASE 1.7.2 Enhancements to ALTER TABLE ADD COLUMN and DROP COLUMN. Fixed bug with closed HTTP connections. Fixed bug with large .data files switching to random access from nio. 2004.06.28 RC_6d The implemntation of UNION, EXCEPT and INTERSECT set operations has been rewritten to comply with SQL standards. When multiple set operations are present in a query, they are now evaluated from left to right, with INTERSECT taking precedence over the rest. It is now possible to use parentheses around multiple (or single) select statements with set operations to change the order of evalation.E.g.: ((SELECT * FROM A EXCEPT SELECT * FROM B) INTERSECT SELECT * FROM D UNION SELECT * FROM E) Timestamp, date and time values in TEXT TABLE source files are treated more leniently, allowing spaces before values. 2004.06.19 RC_6c Fixed bug in default value definition. Fixed bug in getURL() for internal connections Fixed bug in evaluation of BOOLEAN values Fixed bug in Statement.executeBatch() Improvements in CHECKPIONT DEFRAG Improvements in nio .data file handling Added a procedural language to SqlTool. Made error handling and control more robust. Implemented several new features. Updated documentation 2004.05.31 RC_6b Fixed CHECKPOINT DEFRAG bug with empty tables Fixed ORDER BY with HAVING Fixed SELECT .. INTO table issue with outer joins etc. Fixed issue with NOT used in WHERE clause of OUTER select Fixed issue with DAYOFWEEK() etc. library calls with NULL parameter Fixes for TRIGGER thread termination Fixes for minor bugs Updated documentation 2004.05.18 RC_6a Fix for two bugs, some doc updates, etc. 2004.05.17 RC_6 Final Release Candidate This is the final release candidate for 1.7.2. More tests are required to verify the improvements. Please perform tests and report any issues. Testers are needed for build scripts with different JVM's using both ANT and batch builds. Documentation has been updated and is available in HTML and PDF formats. More bug fixes to engine and JDBC classes. Bug fixes and minor enhancements to Database Manager and Transfer tools. Database Manager Swing table view is sortable. Fixed bug with different values in one row with multiple CURRENT_TIMESTAMP or NOW() calls. Introduction of CURRENT_USER, can be used as column default value as well. CURRENT_TIMESTAMP, NOW, TODAY etc. should not be quoted when used as column default values. Improvements to PreparedStatement set stream methods. Improvements to Clob and Blob implementations. Much of the UNIX init script redesigned. Now supports TLS and WebServer. 2004.05.01 Small improvements in different areas CURRENT_TIME, CURRENT_DATE, CURRENT_TIMESTAMP and their aliases can now be used in views and prepared statements. Some bug fixes and updates to utility programs. Improvements to cascading update operations, allowing full capability with FK's referencing the same table. Improved parametric INSERT .... SELECT. CHECKPOINT DEFRAG now works with nio mode .data files. DATEDIFF function has been added. 2004.04.01 RC_5 Some bug fixes. 2004.03.22 RC_4 Included hsqldb.jar has been compiled with JDK 1.4 and will not work with JRE 1.3.x or earlier. Please recompile with JDK 1.3 for use with this or earlier JDK's. Improvements to ALTER TABLE when VIEWS reference the table Enhancements to Server Bug fixes for: BIGINT values in IN predicate value lists. Creation of self ref foreign keys. Corrupted log file with SET AUTOCOMMIT SET LOGSIZE Bug fixes for LIKE with default local and ALTER TABLE with CHECK 2004.03.13 RC_3 Various bug fixes. 2004.02.22 RC_2 Release Candidate 2 for HSQLDB version 1.7.2 includes almost all of the features of the release version. It is possible that by the time of the release, a small number of minor features will be added or changed. One area that is likely to change is the SQL_STATE values for errors returned by JDBC. Changes since RC_1 Constraint names must be unique within each database. Refactoring groups of classes into new packages. This change is internal and does not affect the use of hsqldb. New SqlTool and SqlFile utilities by Blaine Simpson. See hsqlSqlTool.html for details. Support for new system tables for constraints, views and sequences. Support for increments in GENERATED BY DEFAULT AS IDENTITY(START WITH , INCREMENT BY >) Support for table aliases in UPDATE BOOLEAN is now the default SQL type for boolean values. BIT is treated as an alias for BOOLEAN in table definition and queries. Library function CURTIME() changed to return CURRENT_TIME instead of CURRENT_TIMESTAMP Added logging for sequence generation Bug Fixes since RC_1 Values for BOOLEAN expressions containing AND, OR, LIKE and used in columns returned by queries are now correct. Fixed issue with single value selects in UPDATE and SELECT statements. Fixed issue with Turkish Locale. Fixed issue with compiled statements. Added mutable object cloning and serialization on PrepredStatement parameter entry points for in-process connections. Isolates the stored objects (DATETIME, BINARY and OTHER) from subsequent changes made to the copy used for setting the parameter. To do same for Result. More extensive error message when internal asserts fail. Various other bug fixes. 2003.12.28 RC_1 Release Candidate 1 for HSQLDB version 1.7.2 includes most of the features of the release version. It is likely that by the time of the release, a small number of features will be added to the engine. One area that is likely to change is the SQL_STATE values for errors returned by JDBC. Changes since ALPHA_T Added referential integrity checks when a foreign key is added to a populated table. support for SQL style SEQUENCE objects. support for DROP INDEX IF EXISTS Changes to SET PROPERTY command with better error checking. Added support for LIMIT ? ? and TOP ? (prepared statement) Fixed reported bugs including order by with UNION. Added support for aggregate functions in CASEWHEN, IFNULL, etc. Added support for aggregate functions as arguments to non-aggregate functions. Views and subqueries can appear in a view definition. 2003.10.26 HSQLDB 1.7.2 ALPHA_T Improved index use for multiple key joins. 2003.10.24 Fixed some reported and unreported bugs. View definitions can now have a column name list: CREATE VIEW [(, ...)] AS SELECT .... 2003.10.21 HSQLDB 1.7.2 ALPHA_S Fixed name resolution issues in some IN (SELECT ...) and EXISTS (SELECT ...) queries. Optimisation of these queries when not correlated. Speed optimisation of joins with views and subqueries. Fixed LIKE parameter bug. Support for CHECK constraints that apply to the modified/inserted row only. This can be added via ALTER TABLE ADD CHECK() or in table definition. Fixed the DATETIME normalisation issues. Fixed ResultSet.isAfterLast() issue. Reverted column name case in ResultSet methods to JDBC compliance. 2003.10.12 HSQLDB 1.7.2 ALPHA_R This release features full support for prepared statements with parameters, including those in IN lists. Query processing has been extensively enhanced in this release and better standards compliance has been achieved. Major implications of the recent changes are as follows: - Columns in correlated subqueries are resolved independently first. If there is an unresolved column, then the surrounding context is used to resolve it. This is opposite the resolution order previously enforced in the engine. - Some ambiguities and errors in ORDER BY clauses are now caught. - UNION and other set queries accept only one ORDER BY clause at the end. In this clause, only column indexes are allowed as sort specification e.g.: SELECT .. UNION SELECT .. ORDER BY 1 DESC, 5, 3 - Outer join conditions can now include most comparison operators, as well as OR logical operators , e.g LEFT OUTER JOIN atable ON a=b AND c>d OR a=2 ... Illegal forward table references are no longer allowed in join conditions. There are many other small improvements and fixes, including: - IN value lists can now contain column values or expressions. See TestSelfQueries.txt for an example. - LIKE has been optimised when possible. - COALESCE() can now take several arguments 2003.09.24 HSQLDB 1.7.2 ALPHA_Q The problem with PreparedStatement parameters in IN lists still remains to be fixed. This release includes some bug fixes and improvements. In the /doc directory there is a new how-to document on using HSQLDB in OpenOffice.org. HSQLDB 1.7.2 ALPHA_P Apart from the bugs and limitations of PreparedStatement, all the bugs reported since the release of ALPHA_O have been fixed in this alpha version. Some minor enhancements have been made to increase compatibility with OpenOffice.org applications. In addition, it is now possible to execute triggers in the main execution thread. This allows uses for triggers that were not possible before. HSQLDB 1.7.2 ALPHA_O Due to the large number of small bug fixes since the release of ALPHA_N, a new ALPHA_0 version is now released. Please see the bug tracker for a list of some of the bugs that have been fixed. This version does not yet support prepared statements with IN(?,?) parameters. Please report any bugs or suggestions through the normal channels. Bugs with test cases should be posted to the bug tracker on the HSQLDB Sourceforge site. A new JDBC connection property "toupper_column_name" can be used when the application program submits lowercase / mixedcase column names to Result.getXXX(String column) methods when the names are in fact UPPERCASE as they were not quoted when the table was created. The default value is false. See related documentation in hsqldbAdvancedGuide.html on how to set this property value. (this property was subsequently dropped) The rest of the information for ALPHA_N below applies to this version too. HSQLDB 1.7.2 ALPHA_N ALPHA_N is the ultimate ALPHA version for the 1.7.2 release cycle. Known deficiencies and reported bugs will be addressed for the first Release Candidate to be issued in the next few weeks. Please report any bugs or suggestions through the normal channels. Bugs with test cases should be posted to the bug tracker on the HSQLDB Sourceforge site. The included documentation has been updated. The JavaDoc for the jdbcXXX classes covers the JDBC interface. You can make the JavaDoc via the build scripts. The jar has been compiled with JDK 1.4. To run under earlier JDK's recompile using JDK 1.3.x. Changes since 1.7.2 are listed here in the reverse chronological order. 2003.09.02 ADDED JDBC SUPPORT FOR SAVPOINTS 2003.08.22 FURTHER SPEED IMPROVEMENTS IN ALL LOGGED MODES INSERT and UPDATE ops are faster by 5-20% in MEMORY tables, less in CACHED tables. ADDED SUPPORT FOR A RANGE OF SQL STYLE FUNCTIONS: CASE .. WHEN ... THEN .. ELSE ... END CASE WHEN .. THEN .. ELSE ... END NULLIF(.. , ..) SUBSTRING(.. FROM .. FOR ..) POSITION(.. IN ..) TRIM( {LEADING | TRAILING .. } FROM ..) EXTRACT({DAY | TIME |..} FROM ..) COALESCE(.. , ..) 2003.08.17 FURTHER IMPROVEMENTS IN PREPARED STATEMENT EXECUTION SPEED SUPPORT FOR JDBC BATCH EXECUTION SUPPORT FOR MULTIPLE ROWS WITH NULL FIELDS UNDER UNIQUE CONSTRAINTS IMPROVEMENTS TO TestSelf IMPROVEMENTS TO ON UPDATE CASCADE / SET DEFAULT / SET NULL 2003.08.11 REWRITE OF LEFT OUTER JOIN SUPPORT - Complete rewrite of join processing abolishes the requirement for an index on any joined columns. All expressions with AND are supported in the join condition (JOIN atable ON ....) IMPROVEMENTS TO ON DELETE CASCADE / SET DEFAULT / SET NULL - Self referencing foreign keys and multiple foreign keys now support ON DELETE CASCADE. 2003.08.02 NIO ACCESS FOR .data FILES New nio access layer for .data files speeds up most CACHED TABLE related operations very significantly. 90% speedups in TestCacheSize tests have been observed. The program must be compiled with JDK 1.4 and run in a 1.4 JRE to use the new access mode. IMPROVEMENTS TO UPDATE AND INSERT Certain types of UPDATES and INSERTS that previously failed due to blanket application of UNIQUE constraints now work. Examples include UPDATE ... SET col = col + 1 where col is an identity column or INSERT a self referencing row under FOREIGN key constraints. 2003.07.30 IMPORTANT FIX IN SELECT QUERY PROCESSING Problems with OUTER and INNER joins returning incorrect results have been reported over the last couple of years. A new fix is intended to ensure correct results in all cases. - When two tables are joined, rows resulting from joining null values in the joined columns are no longer returned. - Use of OUTER requires the existence of an index on a joined OUTER column - There are still limitations on the conditions used in OUTER joins. AGGREGATES - enhancements to aggregate functions: aggregates of different numeric types are now supported SUM returns a BIGINT for TINYINT, SMALLINT and INTEGER columns. It returns a DECIMAL for BIGINT columns (scale 0) and DECIMAL columns scale equals to that of the column). AVG returns the same type as the column or the expression in its argument. - aggregates with GROUP BY do not return any rows if table is empty OLDER ENHANCEMENTS NOT PREVIOUSLY REPORTED - IDENTITY columns can now be of BIGINT type: CREATE TABLE ( BIGINT IDENTITY, ...) - With contributed patch, TEXT TABLES encoding of the source file can now be specified. UTF-8 and other encodings can be used. - Two new options for databases: files_readonly and files_in_jar were added based on submitted patches. FILE READ-ONLY If the property files_readonly=true is set in the database .properties file, no attempt is made to write the changes to data to file. Default, memory tables can be read/write but TEXT and CACHED tables are treated as read-only. FILES IN JAR This option allows database files to be distributed in the application jar. We have changed the original contribution so that a special URL is used for this mode in the form of: jdbc:hsqldb:res: The URL type 'res' determines that the path that follows is a path into the JAR. The database can be readonly or files_readonly, depending on the value set in .properties file. 2003.07.09 SCRIPT FORMAT - change to command previously named SET LOGTYPE (discussed below for earlier alphas) new form is: SET SCRIPTFORMAT {TEXT | BINARY | COMPRESSED } The new binary and compressed formats are not compatible with previous ones, so you should change any old 1.7.2 ALPHA_? database to text mode with SET LOGTYPE 0 before opening with the new version. 'OTHER' DATA TYPE - change to handling of OTHER columns. It is no longer required that the classes for objects stored in OTHER columns to be available on the path of an HSQLDB engine running as a server. Classes must be available on the JDBC client's path. OBJECT POOLING - the new Object pool has been incorporated. This reduces memory usage to varying degrees depending on the contents of database tables and speeds up the database in most cases. Currently the size of the pool is hard-coded but it will be user adjustable in the release version. CONNECTION PROPERTY - a new property, ifexists={true|false} can be specified for connections. It has an effect only on connections to in-process databases. The default is false and corresponds to current behaviour. If set true, the connection is opened only if the database files have already been created -- otherwise no new database is created and the connection attempt will fail. Example: jdbc:hsqldb:hsql:mydb;ifexists=true This property is intended to reduce problems resulting from wrong URL's which get translated to unintended new database files. It is recommended to use this property for troubleshooting. 2003.07.04 PREPARED STATEMENTS - support for real PreparedStatements - major speedup. Current limitations include lack of support for parameters in IN() predicates of queries. TRANSACTIONS VIA WEB SERVER - uniform support for transactions via HSQL and HTTP (WebServer and Servlet) protocols MULTIPLE IN-MEMORY AND SERVERS DATABASES - support for multiple memory-only databases within the same JVM - support for simultaneous multiple servers, multiple internal connections and multiple databases within the same JVM NEW CONVENTIONS FOR URL'S AND .properties FILES Each HSQLDB server or webserver can now serve up to 10 different databases. The server.properties and webserver.properties method for defining the databases has changed. The following properties should be used: server.database.0 path_of_the_first_database server.dbname.0 alias_for_the_first_database Up to 10 databases can be defined but they must start from 0 The same applies to command line arguments for Server and WebServer. The urls for connecting to servers should have the alias of the database at the end. For example, to connect to the HSQL protocol server on the localhost use: jdbc:hsqldb:hsql://localhost/alias_for_the_database where alias_for_the_database is the same string as defined in server.properties as server.dbnam.n The default for server.dbname.0 is "" (empty string) so that old URL types continue to work. Multiple memory-only database are supported by the use of: jdbc:hsqldb:mem:alias_for_the_first_database jdbc:hsqldb:mem:alias_for_the_second_database Examples: jdbc:hsqldb:mem:db1 jdbc:hsqldb:mem:mydb The conneciton type, 'file', can be used for file database connections. example below: jdbc:hsqldb:hsql:file:mydb;ifexists=true The URL for connecting to a Servlet HTTP server must have a forward-slash at the end. Servlet serves only one database. jdbc:hsqldb:hsql://localhost:8080/servlet/HsqlServlet/ 2003.03.10 DATABASE METADATA -system table support and java.sql.DatabaseMetadate results have been overhauled by Campbell. STRICT FOREIGN KEYS -strict treatment of foreign key index requirements is now enforced. A foreign key declaration _requires_ a unique constraint or index to exist on the columns of the referenced table. This applies both to old and new databases. Duplicate foreign keys (with exactly the same column sets) are now disallowed. TEXT TABLES -further improvements to TEXT table support. Smaller cache sizes are now the default and the default properties can be specified in the *.properties file. HSQLDB 1.7.2 ALPHA_M 2003.01.23 -fixed reported bugs in SHUTDOWN COMPACT -fixed reported bugs in GRANT statements on system tables -fixed bug that prevented UPDATE in some circumstances some enhancements that appeared in previous versions but not reported: -enhanced handling of DATE objects - comparability and normalisation -support for CLOB methods in ResultSet -fixed bug in afterLast() followed by previous() in ResultSet HSQLDB 1.7.2 ALPHA_L 2003.01.16 various patches and fixes -fixes new issues reported with ALPHA_K -fixes old issues related to uncommitted transactions in abnormal shutdown -fixes old issues with SAVEPOINT names -enhanced TEXT table handling and reporting of errors in CSV (source) files HSQLDB 1.7.2 ALPHA_K 2003.01.10 various patches and fixes -OUTER with multiple column joins is now supported while OR is disallowed in the join expression. It is now possible to specify a range or equality condition on the OUTER columns returned. -submitted patch for exclusion of NULL values from results of range queries has been applied. e.g. WHERE columnvalue < 3 will exclude from the result all rows with NULL in columnvalue. -a number of small enhancements and bug fixes. further enhancements to logging. -The *.script file now contains only the DDL and data that is written at CHECKPOINT or SHUTDOWN. The statements logged while the engine is running are stored in a *.log file. -The format of the *.script file can now be one of TEXT, BINARY or COMPRESSED. The SET LOGTYPE {0|1|3} will reset the format. A checkpoint is performed at this point if the format is different from the existing one. The COMPRESSED format has the side benefit of hiding the DDL and the admin password. -The behaviour of SET WRITE_DELAY has changed with the introduction of the sync() method to force the log to be written out completely to disk at given intervals. SET WRITE_DELAY {TRUE | FALSE} is interpreted as synch every 60 seconds or 1 second. SET WRITE_DELAY where n is an integer is interpreted as synch every n seconds. The current default is 60 seconds which seems to provide the right balance. The performance impact of SET WRITE_DELAY 1 is probably about 15% over that of SET WRITE_DELAY 300. -The recovery from crash has been modified so that any line in the log that is not properly written (and causes an error) ends the redo process. A message is reported to the user, instead of stopping engine operation. HSQLDB 1.7.2 ALPHA_J 2002.12.24 CVS hsqldb-dev module tag: HSQLDB_1_7_2_ALPHA_J -More work on text tables. See hsqlTextTables.html. -Some refactoring of Table.java and Parser.java HSQLDB 1.7.2 ALPHA_I 2002.12.16 CVS hsqldb-dev module tag: HSQLDB_1_7_2_ALPHA_I More work on core classes to consolidate previous changes -correction of reported bug with text tables and primary keys -reducing data file writes esp. with big rows -preventing Cache related error in ON DELETE CASCADE HSQLDB 1.7.2 ALPHA_H 2002.12.11 CVS hsqldb-dev module tag: HSQLDB_1_7_2_ALPHA_H Reduction in JDK / JRE dependencies (see readmebuild.txt) Extensive refactoring of some of the larger classes. More changes to core classes Node, Row, Index, Cache, Log ... Some minor bug fixes and enhancements. Enhancements to text table support, including binary columns. Bug fixes to User.java and UserManager.java. Support for ON UPDATE / DELETE SET NULL / SET DEFAULT SSL support for Server mode operation. 2002.10.30 HSQLDB 1.7.2 ALPHA_G CVS hsqldb-dev module tag: HEAD data: 2002.10.30 New features include: Tony Lai's enhancements to aggratates and support for HAVING. Tony's new UnifiedTable class (provisional name) which he kindly wrote at my request and provides sorted arrays with minimal storage requirements. My refactoring work on DatabaseRowInput/Output subclasses and Cache.java. This is still ongoing and has several features aimed at a more robust database engine, including: - reduction in object creation; - possibility of resizing the cache while the engine is running; - possibility of exporting and backing up the DB files while the engine is running. I have implemented the new feature, CHECKPOINT DEFRAG to defragment a *.data file without shutting down the engine, in two different versions, taking advantage of the above improvements. I have implemented binary logging of MEMORY table inserts in the *.script file, resulting in much smaller startup and shutdown times with large memory tables. Use SET LOGTYPE {0|1} to set the log type to text (0) or binary (1). This performs a checkpoint if the type needs changing. Also further performance optimisations resulting in faster CACHED table operations have been made. Sebastian has implemented ON UPDATE CASCADE support for foreign keys.hsqldb-1.8.0.10.orig/doc/databaseinjar.txt0000644000175000017500000000366010036532315016720 0ustar renerene Mask Builder PUI Demonstration of JNLP hsqldb-1.8.0.10.orig/doc/readme-docauthors.txt0000644000175000017500000001143610242427031017533 0ustar renereneHOW TO CREATE AND WORK WITH DOCBOOK DOCUMENTS FOR HSQLDB At some point, this document itself should be converted to DocBook format. Our DocBook strategy is still subject to change. For now... TO CREATE A NEW DOCBOOK BOOK Think up a base filename for your document. It should be nice and short, without funny characters (but hyphens, other than leading hypends, are ok). Example: sqltool. Hereafter, I'll refer to this as your "book name". Create a subdirectory of "docsrc" with name of your book name. I'll refer to this directory (docsrc + book name) as "your book directory". Inside your book directory, create your main DocBook source file with name of your book name + ".xml", e.g. "sqltool.xml". Your DocBook document may reference or include shared files in the main 'docsrc' directory as well as any files which you put into your book directory. You may want to include sample .java files, screen shots, or component DocBook source files. Usually you will just copy these files right into your book directory. For examples of just about everything, see .../docsrc/sqltool/sqltool.xml. Notice that sqltool.xml pulls in a document section from the main docsrc directory. Add your book name to the .cvsignore file in the doc directory. Until all of the CVS artifacts are moved out of the "doc" directory, you will need to edit the clean-doc target in the build.xml file in the build directory so that it will remove the derived files for your book from under the doc directory. HOW TO REFERENCE OR INCLUDE OTHER FILES IN YOUR DOCBOOK SOURCE FILE(s). To link to outside documents (which you supply or not), you'll usually use the DocBook element. To "import" other documents, just use the general external parsed entity mechanism. This is a basic DTD-style XML feature where you use macros like &entityname;. Either find an XML reference or look around our existing DocBook source files for an example to follow. One tricky point is how to include external files verbatim. If you just read in external files as parsed entities, they will be parsed as DocBook source (and therefore they must consist of, at least, legal XML)*. But often you will want to import a real, working file (like a configuration file, sql file, Java source file), and you won't want to hack it up just so you can import it. (For one thing, you shouldn't have to; for another, you may want to provide a link to the file for download, so you wouldn't want people to download a hacked-up version). It would be nice if you could CDATA, then include the entity, but that won't work since the &...; inclusion directive would thereby be escaped. If you don't know what the hell CDATA is, just follow the instructions in the next paragraph. To import a document verbatim, define an external parsed entity for the file ../../docwork/BOOKNAME/cdata/file.name, where BOOKNAME is your book name and file.name is the name of the file to be imported (which resides in the current directory). If you want to know, what will happen is, the Ant build will copy the file-to-be-imported to the directory .../docwork/BOOKNAME/cdata and will sandwich it in a CDATA directive. If you want to provide a link to the document, you just ulink to the document in the current directory, not to the one in the cdata POSTNOTE: The long-term way to do this is with XInclude, or some other generic XML inclusion mechanism. Unfortunately, none of the good methods work with the Java ports of DocBook! ======================================================================= CONVENTIONS Please use elements to mark up notes for yourself or for other developers. All s should be removed before the doc goes public! Please capitalize HSQLDB like "Hsqldb" in titles, and capitalize like "HSQLDB" elsewhere. (In filepaths and package names you code as required for the filepath or package name, of course). ======================================================================= TIPS When closing DocBook and elements, make sure that there is no line break after the text to display and before the closing or tag. Otherwise the resultant display will not look right. Don't capitalize words or phrases to emphasize them (including in section titles or headings). If you want to emphasize something a certain way, then use a DocBook emphasis role, and leave the presentation decisions to the style sheets. It is very easy to set a CSS style to capitalize headings if you want them to appear that way. * Theoretically it would be better and SHOULD be simpler to use unparsed entities for this purpose, but unparsed entities are a messy legacy feature of DTD which is more convoluted than the strategy described here. hsqldb-1.8.0.10.orig/doc/guide/0000755000175000017500000000000011020620762014455 5ustar renerenehsqldb-1.8.0.10.orig/doc/guide/pr01.html0000644000175000017500000001171410665324645016150 0ustar renereneIntroduction

                Introduction

                The HSQLDB jar package is located in the /lib directory and contains several components and programs. Different commands are used to run each program.

                Components of the Hsqldb jar package

                • HSQLDB RDBMS

                • HSQLDB JDBC Driver

                • Database Manager (Swing and AWT versions)

                • Query Tool (AWT)

                • Sql Tool (command line)

                The HSQLDB RDBMS and JDBC Driver provide the core functionality. The rest are general-purpose database tools that can be used with any database engine that has a JDBC driver.

                Running Tools

                All tools can be run in the standard way for archived Java classes. In the following example the AWT version of the Database Manager, the hsqldb.jar is located in the directory ../lib relative to the current directory.

                    java -cp ../lib/hsqldb.jar org.hsqldb.util.DatabaseManager

                If hsqldb.jar is in the current directory, the command would change to:

                    java -cp hsqldb.jar org.hsqldb.util.DatabaseManager

                Main classes for the Hsqldb tools

                • org.hsqldb.util.DatabaseManager

                • org.hsqldb.util.DatabaseManagerSwing

                • org.hsqldb.util.Transfer

                • org.hsqldb.util.QueryTool

                • org.hsqldb.util.SqlTool

                Some tools, such as the Database Manager or SQL Tool, can use command line arguments or entirely rely on them. You can add the command line argument -? to get a list of available arguments for these tools. Database Manager features a graphical user interface and can be explored interactively.

                Running Hsqldb

                HSQLDB can be run in a number of different ways. In general these are divided into Server Modes and In-Process Mode (also called Standalone Mode). A different sub-program from the jar is used to run HSQLDB in each mode.

                Each HSQLDB database consists of between 2 to 5 files, all named the same but with different extensions, located in the same directory. For example, the database named "test" consists of the following files:

                • test.properties

                • test.script

                • test.log

                • test.data

                • test.backup

                The properties files contains general settings about the database. The script file contains the definition of tables and other database objects, plus the data for non-cached tables. The log file contains recent changes to the database. The data file contains the data for cached tables and the backup file is a zipped backup of the last known consistent state of the data file. All these files are essential and should never be deleted. If the database has no cached tables, the test.data and test.backup files will not be present. In addition to those files, HSQLDB database may link to any formatted text files, such as CSV lists, anywhere on the disk.

                While the "test" database is operational, a test.log file is used to write the changes made to data. This file is removed at a normal SHUTDOWN. Otherwise (with abnormal shutdown) this file is used at the next startup to redo the changes. A test.lck file is also used to record the fact that the database is open. This is deleted at a normal SHUTDOWN. In some circumstances, a test.data.old is created and deleted afterwards.

                Note

                When the engine closes the database at a shutdown, it creates temporary files with the extension .new which it then renames to those listed above.

                Server Modes

                Server modes provide the maximum accessibility. The database engine runs in a JVM and listens for connections from programs on the same computer or other computers on the network. Several different programs can connect to the server and retrieve or update information. Applications programs (clients) connect to the server using the HSQLDB JDBC driver. In most server modes, the server can serve up to 10 databases that are specified at the time of running the server.

                Server modes can use preset properties or command line arguments as detailed in the Advanced Topics chapter. There are three server modes, based on the protocol used for communications between the client and server.

                Hsqldb Server

                This is the preferred way of running a database server and the fastest one. A proprietary communications protocol is used for this mode. A command similar to those used for running tools and described above is used for running the server. The following example of the command for starting the server starts the server with one (default) database with files named "mydb.*".

                    java -cp ../lib/hsqldb.jar org.hsqldb.Server -database.0 file:mydb -dbname.0 xdb

                The command line argument -? can be used to get a list of available arguments.

                Hsqldb Web Server

                This mode is used when access to the computer hosting the database server is restricted to the HTTP protocol. The only reason for using the Web Server mode is restrictions imposed by firewalls on the client or server machines and it should not be used where there are no such restrictions. The HSQLDB Web Server is a special web server that allows JDBC clients to connect via HTTP. From 1.7.2 this mode also supports transactions.

                To run a web server, replace the main class for the server in the example command line above with the following:

                    org.hsqldb.WebServer

                The command line argument -? can be used to get a list of available arguments.

                Hsqldb Servlet

                This uses the same protocol as the Web Server. It is used when a separate servlet engine (or application server) such as Tomcat or Resin provides access to the database. The Servlet Mode cannot be started independently from the servlet engine. The Servlet class, in the HSQLDB jar, should be installed on the application server to provide the connection. The database is specified using an application server property. Refer to the source file org.hsqldb.Servlet.java to see the details.

                Both Web Server and Servlet modes can only be accessed using the JDBC driver at the client end. They do not provide a web front end to the database. The Servlet mode can serve only a single database.

                Please note that you do not normally use this mode if you are using the database engine in an application server.

                Connecting to a Database running as a Server

                Once an HSQLDB server is running, client programs can connect to it using the HSQLDB JDBC Driver contained in hsqldb.jar. Full information on how to connect to a server is provided in the Java Documentation for jdbcConnection (located in the /doc/src directory of HSQLDB distribution. A common example is connection to the default port (9001) used for the hsql protocol on the same machine:

                Example 1.1. Java code to connect to the local Server above

                    try {
        Class.forName("org.hsqldb.jdbcDriver" );
    } catch (Exception e) {
        System.out.println("ERROR: failed to load HSQLDB JDBC driver.");
        e.printStackTrace();
        return;
    }

    Connection c = DriverManager.getConnection("jdbc:hsqldb:hsql://localhost/xdb", "sa", "");

                In some circumstances, you may have to use the following line to get the driver.

                    Class.forName("org.hsqldb.jdbcDriver").newInstance();

                Note in the above connection URL, there is no mention of the database file, as this was specified when running the server. Instead, the value defined for dbname.0 is used. Also, see the Advanced Topics chapter for the connection URL when there is more than one database per server instance.

                Security Considerations

                When HSQLDB is run as a server, network access should be adequately protected. Source IP addresses may be restricted by use of TCP filtering or firewall programs, or standalone firewalls. If the traffic will cross an unprotected network (such as the Internet), the stream should be encrypted (for example by VPN, ssh tunneling, or TLS using the SSL enabled HSQLS and HTTPS variants of the server and web server modes). Only secure passwords should be used-- most importantly, the password for the default system user should be changed from the default empty string. If you are purposefully providing data to the public, then the wide-open public network connection should be used exclusively to access the public data via read-only accounts. (I.e., neither secure data nor privileged accounts should use this connection). These considerations also apply to HSQLDB servers run with the HTTP protocol.

                In-Process (Standalone) Mode

                This mode runs the database engine as part of your application program in the same Java Virtual Machine. For most applications this mode can be faster, as the data is not converted and sent over the network. The main drawback is that it is not possible by default to connect to the database from outside your application. As a result you cannot check the contents of the database with external tools such as Database Manager while your application is running. In 1.8.0, you can run a server instance in a thread from the same virtual machine as your application and provide external access to your in-process database.

                The recommended way of using the in-process mode in an application is to use an HSQLDB Server instance for the database while developing the application and then switch to In-Process mode for deployment.

                An In-Process Mode database is started from JDBC, with the database file path specified in the connection URL. For example, if the database name is testdb and its files are located in the same directory as where the command to run your application was issued, the following code is used for the connection:

                    Connection c = DriverManager.getConnection("jdbc:hsqldb:file:testdb", "sa", "");

                The database file path format can be specified using forward slashes in Windows hosts as well as Linux hosts. So relative paths or paths that refer to the same directory on the same drive can be identical. For example if your database path in Linux is /opt/db/testdb and you create an identical directory structure on the C: drive of a Windows host, you can use the same URL in both Windows and Linux:

                    Connection c = DriverManager.getConnection("jdbc:hsqldb:file:/opt/db/testdb", "sa", "");

                When using relative paths, these paths will be taken relative to the directory in which the shell command to start the Java Virtual Machine was executed. Refer to Javadoc for jdbcConnection for more details.

                Memory-Only Databases

                It is possible to run HSQLDB in a way that the database is not persistent and exists entirely in random access memory. As no information is written to disk, this mode should be used only for internal processing of application data, in applets or certain special applications. This mode is specified by the mem: protocol.

                    Connection c = DriverManager.getConnection("jdbc:hsqldb:mem:aname", "sa", "");

                You can also run a memory-only server instance by specifying the same URL in the server.properties. This usage is not common and is limited to special applications where the database server is used only for exchanging information between clients, or for non-persistent data.

                General

                Closing the Database

                All databases running in different modes can be closed with the SHUTDOWN command, issued as an SQL query. From version 1.7.2, in-process databases are no longer closed when the last connection to the database is explicitly closed via JDBC, a SHUTDOWN is required. In 1.8.0, a connection property, shutdown=true, can be specified on the first connection to the database (the connection that opens the database) to force a shutdown when the last connection closes.

                When SHUTDOWN is issued, all active transactions are rolled back. A special form of closing the database is via the SHUTDOWN COMPACT command. This command rewrites the .data file that contains the information stored in CACHED tables and compacts it to size. This command should be issued periodically, especially when lots of inserts, updates or deletes have been performed on the cached tables. Changes to the structure of the database, such as dropping or modifying populated CACHED tables or indexes also create large amounts of unused file space that can be reclaimed using this command.

                Using Multiple Databases in One JVM

                In the above examples each server serves only one database and only one in-memory database can be created. However, from version 1.7.2, HSQLDB can serve several databases in multiple server modes and allow simultaneous access to multiple in-process and memory-only databases. These capabilities are covered in the Advanced Topics chapter.

                Creating a New Database

                When a server instance is started, or when a connection is made to an in-process database, a new, empty database is created if no database exists at the given path.

                This feature has a side effect that can confuse new users. If a mistake is made in specifying the path for connecting to an existing database, a connection is nevertheless established to a new database. For troubleshooting purposes, you can specify a connection property ifexists=true to allow connection to an existing database only and avoid creating a new database. In this case, if the database does not exist, the getConnection() method will throw an exception.

                Using the Database Engine

                Once a connection is established to a database in any mode, JDBC methods are used to interact with the database. The Javadoc for jdbcConnection , jdbcDriver , jdbcDatabaseMetadata , jdbcResultSet , jdbcStatement , and jdbcPreparedStatement list all the supported JDBC methods together with information that is specific to HSQLDB. JDBC methods are broadly divided into: connection related methods, metadata methods and database access methods. The database access methods use SQL commands to perform actions on the database and return the results either as a Java primitive type or as an instance of the java.sql.ResultSet class.

                You can use Database Manager or other Java database access tools to explore your database and update it with SQL commands. These programs use JDBC internally to submit your commands to the database engine and to display the results in a human readable format.

                The SQL dialect used in HSQLDB is as close to the SQL92 and SQL200n standards as it has been possible to achieve so far in a small-footprint database engine. The full list of SQL commands is in the SQL Syntax chapter.

                Different Types of Tables

                HSQLDB supports TEMP tables and three types of persistent tables.

                TEMP tables are not written to disk and last only for the lifetime of the Connection object. The contents of each TEMP table is visible only from the Connection that was used to populate it; other concurrent connections to the database will have access to their own copies of the table. Since 1.8.0 the definition of TEMP tables conforms to the GLOBAL TEMPORARY type in the SQL standard. The definition of the table persists but each new connections sees its own copy of the table, which is empty at the beginning. When the connection commits, the contents of the table are cleared by default. If the table definition statements includes ON COMMIT PRESERVE ROWS, then the contents are kept when a commit takes place.

                The three types of persistent tables are MEMORY tables, CACHED tables and TEXT tables.

                Memory tables are the default type when the CREATE TABLE command is used. Their data is held entirely in memory but any change to their structure or contents is written to the <dbname>.script file. The script file is read the next time the database is opened, and the MEMORY tables are recreated with all their contents. So unlike TEMP table, the default, MEMORY tables are persistent.

                CACHED tables are created with the CREATE CACHED TABLE command. Only part of their data or indexes is held in memory, allowing large tables that would otherwise take up to several hundred megabytes of memory. Another advantage of cached tables is that the database engine takes less time to start up when a cached table is used for large amounts of data. The disadvantage of cached tables is a reduction in speed. Do not use cached tables if your data set is relatively small. In an application with some small tables and some large ones, it is better to use the default, MEMORY mode for the small tables.

                TEXT tables are supported since version 1.7.0 and use a CSV (Comma Separated Value) or other delimited text file as the source of their data. You can specify an existing CSV file, such as a dump from another database or program, as the source of a TEXT table. Alternatively, you can specify an empty file to be filled with data by the database engine. TEXT tables are efficient in memory usage as they cache only part of the text data and all of the indexes. The Text table data source can always be reassigned to a different file if necessary. Two commands are needed to set up a TEXT table as detailed in the Text Tables chapter.

                With memory-only databases (see above), both MEMORY table and CACHED table declarations are treated as declarations for non-persistent memory tables. TEXT table declarations are not allowed in this mode.

                Constraints and Indexes

                HSQLDB supports PRIMARY KEY, NOT NULL, UNIQUE, CHECK and FOREIGN KEY constraints. In addition, it supports UNIQUE or ordinary indexes. This support is fairly comprehensive and covers multi-column constraints and indexes, plus cascading updates and deletes for foreign keys.

                HSQLDB creates indexes internally to support PRIMARY KEY, UNIQUE and FOREIGN KEY constraints: a unique index is created for each PRIMARY KEY or UNIQUE constraint; an ordinary index is created for each FOREIGN KEY constraint. Because of this, you should not create duplicate user-defined indexes on the same column sets covered by these constraints. This would result in unnecessary memory and speed overheads. See the discussion in the SQL Issues chapter for more information.

                Indexes are crucial for adequate query speed. When queries joining multiple tables are used, there must be an index on each joined column of each table. When range or equality conditions are used e.g. SELECT ... WHERE acol >10 AND bcol = 0, an indexe is required on the acol column used in the condition. Indexes have no effect on ORDER BY clauses or some LIKE conditions.

                As a rule of thumb, HSQLDB is capable of internal processing of queries at over 100,000 rows per second. Any query that runs into several seconds should be checked and indexes should be added to the relevant columns of the tables if necessary.

                SQL Support

                The SQL syntax supported by HSQLDB is essentially that specified by the SQL Standard (92 and 200n). Not all the features of the Standard are supported and there are some proprietary extensions. In 1.8.0 the behaviour of the engine is far more compliant with the Standards than with older versions. The main changes are

                • correct treatment of NULL column values in joins, in UNIQUE constraints and in query conditions

                • correct processing of selects with JOIN and LEFT OUTER JOIN

                • correct processing of aggregate functions contained in expressions or containing expression arguments

                The supported commands are listed in the SQL Syntax chapter. For a well written basic guide to SQL with examples you can consult PostgreSQL: Introduction and Concepts by Bruce Momjian, which is available on the web. Most of the SQL coverage in the book applies also to HSQLDB. There are some differences in keywords supported by one and not the other engine (OUTER, OID's, etc.) or used differently (IDENTITY/SERIAL, TRIGGER, SEQUENCE, etc.).

                JDBC Support

                Since 1.7.2, support for JDBC2 has been significantly extended and some features of JDBC3 are also supported. The relevant classes are thoroughly documented. See the JavaDoc for org.hsqldb.jdbcXXXX classes.

                HSQLDB version 1.8.0 supports the SQL statements and syntax described in this chapter.

                Notational Conventions Used in this Chapter

                [A] means A is optional.

                { B | C } means either B or C must be used.

                [{ B | C }] means either B or C may optionally be used, or nothing at all.

                ( and ) are the actual characters '(' and ')' used in statements.

                UPPERCASE words are keywords

                SQL Commands

                ALTER INDEX[2]

                ALTER INDEX <indexname> RENAME TO <newname>;

                Index names can be changed so long as they do not conflict with other user-defined or sytem-defined names.

                ALTER SEQUENCE[2]

                ALTER SEQUENCE <sequencename> RESTART WITH <value>;

                Resets the next value to be returned from the sequence.

                ALTER SCHEMA[2]

                ALTER SCHEMA <schemaname> RENAME TO <newname>;

                Renames the schema as specified. All objects of the schema will hereafter be accessible only with the new schema name.

                Requires Administrative privileges.

                ALTER TABLE[2]

                ALTER TABLE <tablename> ADD [COLUMN] <columnname> Datatype
    [(columnSize[,precision])] [{DEFAULT <defaultValue> |
    GENERATED BY DEFAULT AS IDENTITY (START WITH <n>[, INCREMENT BY <m>])}] |
    [[NOT] NULL] [IDENTITY] [PRIMARY KEY]
    [BEFORE <existingcolumn>];

                Adds the column to the end of the column list. The optional BEFORE <existingcolumn> can be used to specify the name of an existing column so that the new column is inserted in a position just before the <existingcolumn>.

                It accepts a columnDefinition as in a CREATE TABLE command. If NOT NULL is specified and the table is not empty, then a default value must be specified. In all other respects, this command is the equivalent of a column definition statement in a CREATE TABLE statement.

                If an SQL view includes a SELECT * FROM <tablename> in its select statement, the new column is added to the view. This is a non-standard feature which is likely to change in the future.

                ALTER TABLE <tablename> DROP [COLUMN] <columnname>;

                Drops the column from the table. Will drop any single-column primary key or unique constraint on the column as well. The command will not work if there is any multiple key constraint on the column or the column is referenced in a check constraint or a foreign key.

                It will also fail if an SQL view includes the column.

                ALTER TABLE <tablename> ALTER COLUMN <columnname> RENAME TO <newname>

                Changes a column name.

                ALTER TABLE <tablename> ALTER COLUMN <columnname> SET DEFAULT <defaultvalue>};

                Adds the specified default value to the column. Use NULL to remove a default.

                ALTER TABLE <tablename> ALTER COLUMN <columnname> SET [NOT] NULL

                Sets or removes a NOT NULL constraint for the column.

                ALTER TABLE <tablename> ALTER COLUMN <columnDefinition>;

                This form of ALTER TABLE ALTER COLUMN accepts a columnDefinition as in a CREATE TABLE command, with the following restrictions.

                Restrictions

                • The column must be already be a PK column to accept an IDENTITY definition.
                • If the column is already an IDENTITY column and there is no IDENTITY definition, the existing IDENTITY attribute is removed.
                • The default expression will be that of the new definition, meaning an existing default can be dropped by ommission, or a new default added.
                • The NOT NULL attribute will be that of the new definition (similar to previous item).
                • Depending on the type of change, the table may have to be empty for the command to work. It always works when the type of change is possible in general and the individual existing values can all be converted.
                ALTER TABLE <tablename> ALTER COLUMN <columnname>
    RESTART WITH <new sequence value>

                This form is used exclusively for IDENTITY columns and changes the next automatic value for the identity sequence.

                ALTER TABLE <tablename> ADD [CONSTRAINT <constraintname>]
    CHECK (<search condition>);

                Adds a check constraint to the table. In the current version, a check constraint can reference only the row being inserted or updated.

                ALTER TABLE <tablename> ADD [CONSTRAINT <constraintname>] UNIQUE (<column list>);

                Adds a unique constraint to the table. This will not work if there is already a unique constraint covering exactly the same <column list>.

                This will work only if the values of the column list for the existing rows are unique or include a null value.

                ALTER TABLE <tablename> ADD [CONSTRAINT <constraintname>]
    PRIMARY KEY (<column list>);

                Adds a primary key constraint to the table, using the same constraint syntax as when the primary key is specified in a table definition.

                ALTER TABLE <tablename>
    ADD [CONSTRAINT <constraintname>] FOREIGN KEY (<column list>)
    REFERENCES <exptablename> (<column list>)
    [ON {DELETE | UPDATE} {CASCADE | SET DEFAULT | SET NULL}];

                Adds a foreign key constraint to the table, using the same constraint syntax as when the foreign key is specified in a table definition.

                This will fail if for each existing row in the referring table, a matching row (with equal values for the column list) is not found in the referenced tables.

                ALTER TABLE <tablename> DROP CONSTRAINT <constraintname>;

                Drop a named unique, check or foreign key constraint from the table.

                ALTER TABLE <tablename> RENAME TO <newname>;

                ALTER USER[2]

                ALTER USER <username> SET PASSWORD <password>;

                Changes the password for an existing user. Password must be double quoted. Use "" for an empty password.

                DBA's may change users' base default schema name with the comand 

                ALTER USER <username> SET INITIAL SCHEMA <schemaname>;
                This is the schema which database object names will resolve to for this user, unless overridden as explained in Schema object naming. For reasons of backwards compatibility, the initial schema value will not be persisted across database shutdowns until HSQLDB version 1.8.1. (I.e., INITIAL SCHEMA settings will be lost upon database shutdown with HSQLDB versions lower than version 1.8.1).

                Only an administrator may use these commands.

                CALL

                CALL Expression;

                Any expression can be called like a stored procedure, including, but not only Java stored procedures or functions. This command returns a ResultSet with one column and one row (the result) just like a SELECT statement with one row and one column.

                See also: Stored Procedures / Functions, SQL Expression.

                CHECKPOINT

                CHECKPOINT [DEFRAG[2]];

                Closes the database files, rewrites the script file, deletes the log file and opens the database.

                If DEFRAG is specified, this command also shrinks the .data file to its minimal size.

                See also: SHUTDOWN, SET LOGSIZE.

                COMMIT

                COMMIT [WORK];

                Ends a transaction and makes the changes permanent.

                See also: ROLLBACK, SET AUTOCOMMIT, SET LOGSIZE.

                CONNECT

                CONNECT USER <username> PASSWORD <password>;

                Connects to the database as a different user. Password should be double quoted. Use "" for an empty password.

                See also: GRANT, REVOKE.

                CREATE ALIAS

                CREATE ALIAS <function> FOR <javaFunction>;

                Creates an alias for a static Java function to be used as a Stored Procedure. The function must be accessible from the JVM in which the database runs. Example:

                    CREATE ALIAS ABS FOR "java.lang.Math.abs";

                Note

                The CREATE ALIAS command just defines the alias. It does not validate existence of the target method or its containing class. To validate the alias, use it.

                See also: CALL, Stored Procedures / Functions.

                CREATE INDEX

                CREATE [UNIQUE] INDEX <index> ON <table> (<column> [DESC] [, ...]) [DESC];

                Creates an index on one or more columns in a table.

                Creating an index on searched columns may improve performance. The qualifier DESC can be present for command compatibility with other databases but it has no effect. Unique indexes can be defined but this is deprecated. Use UNIQUE constraints instead. The name of an index must be unique within the whole database.

                See also: CREATE TABLE, DROP INDEX.

                CREATE ROLE[2]

                CREATE ROLE <rolename>;

                Creates the named role with no members. Requires Administrative privileges.

                CREATE SCHEMA[2]

                CREATE SCHEMA <schemaname> AUTHORIZATION <grantee>
    [<createStatement> [<grantStatement>] [...];

                Creates the named schema, with ownership of the specified authorization. The authorization grantee may be a database user or a role.

                Optional (nested) CREATE and GRANT statements can be given only for new objects in this new schema. Only the last nested statement should be terminated with a semicolon, because the first semicolon encountered after "CREATE SCHEMA" will end the CREATE SCHEMA command. In the example below, a new schema, ACCOUNTS, is created, then two tables and a view are added to this schma and some rights on these objects are granted.

                    CREATE SCHEMA ACCOUNTS AUTHORIZATION DBA
        CREATE TABLE AB(A INTEGER, ...)
        CREATE TABLE CD(C CHAHR, ...)
        CREATE VIEW VI AS SELECT ...
        GRANT SELECT TO PUBLIC ON AB
        GRANT SELECT TO JOE ON CD;
                Note that this example consists of one CREATE SCHEMA statement which is terminated by a semicolon.

                Requires Administrative privileges.

                CREATE SEQUENCE[2]

                CREATE SEQUENCE <sequencename> [AS {INTEGER | BIGINT}]
    [START WITH <startvalue>] [INCREMENT BY <incrementvalue>];

                Creates a sequence. The default type is INTEGER. The default start value is 0 and the increment 1. Negative values are not allowed. If a sequence goes beyond Integer.MAXVALUE or Long.MAXVALUE, the next result is determined by 2's complement arithmetic.

                The next value for a sequence can be included in SELECT, INSERT and UPDATE statements as in the following example:

                SELECT [...,] NEXT VALUE FOR <sequencename> [, ...] FROM <tablename>;

                In the proposed SQL 200n and in the current version, there is no way of retreiving the last returned value of a sequence.

                CREATE TABLE

                CREATE [MEMORY | CACHED | [GLOBAL] TEMPORARY | TEMP [2] | TEXT[2]] TABLE <name>
    ( <columnDefinition> [, ...] [, <constraintDefinition>...] )
    [ON COMMIT {DELETE | PRESERVE} ROWS];

                Creates a tables in memory (default) or on disk and only cached in memory. If the database is all-in-memory, both MEMORY and CACHED forms of CREATE TABLE return a MEMORY table while the TEXT form is not allowed.

                Components of a CREATE TABLE command

                columnDefinition
                columnname Datatype [(columnSize[,precision])]
    [{DEFAULT <defaultValue> |
    GENERATED BY DEFAULT AS IDENTITY
    (START WITH <n>[, INCREMENT BY <m>])}] |
    [[NOT] NULL] [IDENTITY] [PRIMARY KEY]

                Default values that are allowed are constant values or certain SQL datetime functions.

                Allowed Default Values in Column Definitions

                • For character column, a single-quoted string or NULL. The only SQL function that can be used is CURRENT_USER.

                • For datetime columns, a single-quoted DATE, TIME or TIMESTAMP value or NULL. Or a datetime SQL function such as CURRENT_DATE, CURRENT_TIME, CURRENT_TIMESTAMP, TODAY, NOW. Each function is allowed for a certain datetime type.

                • For BOOLEAN columns, the literals FALSE, TRUE, NULL.

                • For numeric columns, any valid number or NULL.

                • For binary columns, any valid hex string or NULL.

                Only one identity column is allowed in each table. Identity columns are autoincrement columns. They must be of INTEGER or BIGINT type and are automatically primary key columns (as a result, multi-column primary keys are not possible with an IDENTITY column present). Using the long SQL syntax the (START WITH <n>) clause specifies the first value that will be used. The last inserted value into an identity column for a connection is available using the function IDENTITY(), for example (where Id is the identity column):

                INSERT INTO Test (Id, Name) VALUES (NULL,'Test');
    CALL IDENTITY();
                constraintDefinition
                [CONSTRAINT <name>]
    UNIQUE ( <column> [,<column>...] ) |
    PRIMARY KEY ( <column> [,<column>...] ) |
    FOREIGN KEY ( <column> [,<column>...] )
    REFERENCES <refTable> ( <column> [,<column>...]) 
    [ON {DELETE | UPDATE}
    {CASCADE | SET DEFAULT | SET NULL}][2] |
    CHECK(<search condition>)[2]

                Both ON DELETE and ON UPDATE clauses can be used in a single foreign key definition.

                search condition

                A search condition is similar to the set of conditions in a WHERE clause. In the current version of HSQLDB, the conditions for a CHECK constraint can only reference the current row, meaning there should be no SELECT statement. Sample table definitions with CHECK constraints are in TestSelfCheckConstraints.txt. This file is in the /hsqldb/testrun/hsqldb/ directory of the zip.

                General syntax limitations

                HSQLDB databases are initially created in a legacy mode that does not enforce column size and precision. You can set the property: sql.enforce_strict_size=true to enable this feature. When this property has been set, Any supplied column size and precision for numeric and character types (CHARACTER and VARCHAR) are enforced. Use the command, SET PROPERTY "sql.enforce_strict_size" TRUE once before defining the tables.

                NOT NULL constraints can be part of the column definition only. Other constraints cannot be part of the column definition and must appear at the end of the column definition list.

                TEMPORARY TABLE contents for each session (connection) are emptied by default at each commit or rollback. The optional qualifier ON COMMIT PRESERVE ROWS can be used to keep the rows while the session is open. The default is ON COMMIT DELETE ROWS.

                See also: DROP TABLE.

                CREATE TRIGGER[2]

                CREATE TRIGGER <name> {BEFORE | AFTER} {INSERT | UPDATE | DELETE} ON <table>
    [FOR EACH ROW] [QUEUE n] [NOWAIT] CALL <TriggerClass>;

                TriggerClass is an application-supplied class that implements the org.hsqldb.Trigger interface e.g. "mypackage.TrigClass". It is the fire method of this class that is invoked when the trigger event occurs. You should provide this class, which can have any name, and ensure that this TriggerClass is present in the classpath which you use to start hsqldb.

                Since 1.7.2 the implementation has been changed and enhanced. When the 'fire' method is called, it is passed the following arguments:

                    fire (String name, String table, Object row1[], Object row2[])

                where 'row1' and 'row2' represent the 'before' and 'after' states of the row acted on, with each column being a member of the array. The mapping of members of the row arrays to database types is specified in Data Types. For example, BIGINT is represented by a java.lang.Long Object. Note that the number of elements in the row arrays could be larger than the number of columns by one or two elements. Never modify the last elements of the array, which are not part of the actual row.

                If the trigger method wants to access the database, it must establish its own JDBC connection. This can cause data inconsistency and other problems so it is not recommended. The jdbc:default:connection: URL is not currently supported.

                Implementation note:

                If QUEUE 0 is specified, the fire method is execued in the same thread as the database engine. This allows trigger action to alter the data that is about to be stored in the database. Data can be checked or modified in BEFORE INSERT / UPDATE + FOR EACH ROW triggers. All table constraints are then enforced by the database engine and if there is a violation, the action is rejected for the SQL command that initiated the INSERT or UPDATE. There is an exception to this rule, that is with UPDATE queries, referential integrity and cascading actions resulting from ON UPDATE CASCASE / SET NULL / SET DEFAULT are all performed prior to the invocation of the trigger method. If an invalid value that breaks referential integrity is inserted in the row by the trigger method, this action is not checked and results in inconsistent data in the table.

                Alternatively, if the trigger is used for external communications and not for checking or altering the data, a queue size larger than zero can be specified. This is in the interests of not blocking the database's main thread as each trigger will run in a thread that will wait for its firing event to occur. When this happens, the trigger's thread calls TriggerClass.fire. There is a queue of events waiting to be run by each trigger thread. This is particularly useful for 'FOR EACH ROW' triggers, when a large number of trigger events occur in rapid succession, without the trigger thread getting a chance to run. If the queue becomes full, subsequent additions to it cause the database engine to suspend awaiting space in the queue. Take great care to avoid this situation if the trigger action involves accessing the database, as deadlock will occur. This can be avoided either by ensuring the QUEUE parameter makes a large enough queue, or by using the NOWAIT parameter, which causes a new trigger event to overwrite the most recent event in the queue. The default queue size is 1024. Note also that the timing of trigger method calls is not guaranteed, so applications should implement their own synchronization measures if necessary.

                With a non-zero QUEUE parameter, if the trigger methods modifies the 'row2' values, these changes may or may not affect the database and will almost certainly result in data inconsistency.

                Please refer to the code for org.hsqldb.sample.Trigger and org.hsqldb.sample.TriggerSample for more information on how to write a trigger class.

                CREATE USER

                CREATE USER <username> PASSWORD <password> [ADMIN];

                Creates a new user or new administrator in this database. Password must be double quoted. Empty password can be made using "". You can change a password afterwards using a ALTER USER[2] command.

                Only an administrator can do this.

                See also: CONNECT, GRANT, REVOKE. ALTER USER[2],

                CREATE VIEW[2]

                CREATE VIEW <viewname>[(<viewcolumn>,..) AS SELECT ... FROM ... [WHERE Expression]
[ORDER BY orderExpression [, ...]]
[LIMIT <limit> [OFFSET <offset>]];

                A view can be thought of as either a virtual table or a stored query. The data accessible through a view is not stored in the database as a distinct object. What is stored in the database is a SELECT statement. The result set of the SELECT statement forms the virtual table returned by the view. A user can use this virtual table by referencing the view name in SQL statements the same way a table is referenced. A view is used to do any or all of these functions:

                • Restrict a user to specific rows in a table. For example, allow an employee to see only the rows recording his or her work in a labor-tracking table.

                • Restrict a user to specific columns. For example, allow employees who do not work in payroll to see the name, office, work phone, and department columns in an employee table, but do not allow them to see any columns with salary information or personal information.

                • Join columns from multiple tables so that they look like a single table.

                • Aggregate information instead of supplying details. For example, present the sum of a column, or the maximum or minimum value from a column.

                Views are created by defining the SELECT statement that retrieves the data to be presented by the view. The data tables referenced by the SELECT statement are known as the base tables for the view. In this example, is a view that selects data from three base tables to present a virtual table of commonly needed data:

                    CREATE VIEW mealsjv AS
      SELECT m.mid mid, m.name name, t.mealtype mt, a.aid aid,
             a.gname + ' ' + a.sname author, m.description description,
             m.asof asof
        FROM meals m, mealtypes t, authors a
       WHERE m.mealtype = t.mealtype
        AND m.aid = a.aid;

                You can then reference mealsjv in statements in the same way you would reference a table:

                    SELECT * FROM mealsjv;

                A view can reference another view. For example, mealsjv presents information that is useful for long descriptions that contain identifiers, but a short list might be all a web page display needs. A view can be built that selects only specific mealsjv columns:

                    CREATE VIEW mealswebv AS SELECT name, author FROM mealsjv;

                The SELECT statement in a VIEW definition should return columns with distinct names. If the names of two columns in the SELECT statement are the same, use a column alias to distinguish between them. A list of new column names can always be defined for a view.

                    CREATE VIEW aview (new_name, new_author) AS
      SELECT name, author
      FROM mealsjv

                See also: SQL Expression, SELECT[2], DROP VIEW[2].

                DELETE

                DELETE FROM table [WHERE Expression];

                Removes rows in a table.

                See also: SQL Expression, INSERT, SELECT[2].

                DISCONNECT

                DISCONNECT;

                Closes this connection. It is not required to call this command when using the JDBC interface: it is called automatically when the connection is closed. After disconnecting, it is not possible to execute other queries (including CONNECT) with this connection.

                See also: CONNECT.

                DROP INDEX

                DROP INDEX index [IF EXISTS];

                Removes the specified index from the database. Will not work if the index backs a UNIQUE of FOREIGN KEY constraint.

                See also: CREATE INDEX.

                DROP ROLE[2]

                DROP ROLE <rolename>;

                Removes all members from specified role, then removes the role itself.

                DROP SEQUENCE[2]

                DROP SEQUENCE <sequencename> [IF EXISTS] [RESTRICT | CASCADE];

                Removes the specified sequence from the database. When IF EXIST is used, the statement returns without an error if the sequence does not exist. The RESTRICT option is in effect by default, meaning that DROP will fail if any view reference the sequence. Specify the CASCADE option to silently drop all dependent database objects.

                DROP SCHEMA[2]

                DROP SCHEMA <schemaname> [RESTRICT | CASCADE];

                Removes the specified schema from the database. The RESTRICT option is in effect by default, meaning that DROP will fail if any objects such as tables or sequences have been defined in the schema. Specify the CASCADE option to silently drop all database objects in the schema.

                Requires Administrative privileges.

                DROP TABLE

                DROP TABLE <table> [IF EXISTS] [RESTRICT | CASCADE];

                Removes a table, the data and indexes from the database. When IF EXIST is used, the statement returns without an error even if the table does not exist.

                The RESTRICT option is in effect by default, meaning that DROP will fail if any tables or views refer to this table. Specify the CASCADE option to silently drop all dependent views, and to drop any foreign key constraint that links this table with other tables.

                See also:

                CREATE TABLE.

                DROP TRIGGER

                DROP TRIGGER <trigger>;

                Removes a trigger from the database.

                See also: CREATE TRIGGER[2].

                DROP USER

                DROP USER <username>;

                Removes a user from the database.

                Only an administrator do this.

                See also: CREATE USER.

                DROP VIEW[2]

                DROP VIEW <viewname> [IF EXISTS] [RESTRICT | CASCADE];

                Removes a view from the database. When IF EXIST is used, the statement returns without an error if the view does not exist. The RESTRICT option is in effect by default, meaning that DROP will fail if any other view refers to this view. Specify the CASCADE option to silently drop all dependent views.

                See also: CREATE VIEW[2].

                EXPLAIN PLAN

                EXPLAIN PLAN FOR { SELECT ... | DELETE ... | INSERT ... | UPDATE ..};

                EXPLAIN PLAN FOR can be used with any query to get a detailed list of the elements in the execution plan.

                This list includes the indexes used for performing the query and can be used to optimise the query or to add indexes to tables.

                GRANT

                GRANT { SELECT | DELETE | INSERT | UPDATE | ALL } [,...]
ON { table | CLASS "package.class" } TO <grantee>;
                GRANT <rolename> [,...] TO <grantee>[2];

                <grantee> is either a user name, a role name, or PUBLIC. PUBLIC means all users.

                The first form of the GRANT command assigns privileges to a grantee for a table or for a class. To allow a user to call a Store Procedure static function, the right ALL must be used. Examples: 

                    GRANT SELECT ON Test TO GUEST;
    GRANT ALL ON CLASS "java.lang.Math.abs" TO PUBLIC;

                Warning

                Even though the command is GRANT ALL ON CLASS, you must specify a static method name. You are actually granting access to a static method, not to a class.

                The second form of the GRANT command gives the specified <grantee> membership in the specified role.

                Requires Administrative privileges.

                See also: REVOKE, CREATE USER, CREATE ROLE[2].

                INSERT

                INSERT INTO table [( column [,...] )]
{ VALUES(Expression [,...]) | SelectStatement};

                Adds one or more new rows of data into a table.

                REVOKE

                REVOKE { SELECT | DELETE | INSERT | UPDATE | ALL } [,...]
ON { table | CLASS "package.class" } FROM <grantee>;
                REVOKE <rolename> [,...] FROM <grantee>[2];

                <grantee> is either a user name, a role name, or PUBLIC. PUBLIC means all users.

                The first form of the REVOKE command withdraws privileges from a grantee for a table or for a class.

                The second form of the REVOKE command withdraws membership of the specified <grantee> from the specified role.

                Both forms require Administrative privileges.

                See also: GRANT.

                ROLLBACK

                ROLLBACK [TO SAVEPOINT <savepoint name>[2] |  WORK}];

                ROLLBACK used on its own, or with WORK, undoes changes made since the last COMMIT or ROLLBACK.

                ROLLBACK TO SAVEPOINT <savepoint name> undoes the change since the named savepoint. It has no effect if the savepoint is not found.

                See also: COMMIT.

                SAVEPOINT[2]

                SAVEPOINT <savepoint name>;

                Sets up a SAVEPOINT for use with ROLLBACK TO SAVEPOINT.

                See also: COMMIT.

                SCRIPT

                SCRIPT ['file'];

                Creates an SQL script describing the database. If the file is not specified, a result set containing only the DDL script is returned. If the file is specified then this file is saved with the path relative to the machine where the database engine is located.

                Only an administrator may do this.

                SELECT[2]

                SELECT [{LIMIT <offset> <limit> | TOP <limit>}[2]][ALL | DISTINCT]
{ selectExpression | table.* | * } [, ...]
[INTO [CACHED | TEMP  | TEXT][2] newTable]
FROM tableList
[WHERE Expression]
[GROUP BY Expression [, ...]]
[HAVING Expression]
[{ UNION [ALL | DISTINCT] | {MINUS [DISTINCT] | EXCEPT [DISTINCT] } |
INTERSECT [DISTINCT] } selectStatement]
[ORDER BY orderExpression [, ...]]
[LIMIT <limit> [OFFSET <offset>]];

                Retrieves information from one or more tables in the database.

                Components of a SELECT command

                tableList
                table [{CROSS | INNER | LEFT OUTER | RIGHT OUTER}
    JOIN table ON Expression] [, ...]
                table
                { (selectStatement) [AS] label | tableName}
                selectExpression
                { Expression | COUNT(*) | {
    COUNT | MIN | MAX | SUM | AVG | SOME | EVERY |
    VAR_POP | VAR_SAMP | STDDEV_POP | STDDEV_SAMP
} ([ALL | DISTINCT][2]] Expression) } [[AS] label]

                If DISTINCT is specified, only one instance of several equivalent values is used in the aggregate function. Except COUNT(*), all aggregate functions exclude NULL values. The type of the returned value for SUM is subject to deterministic widenning to ensure lossless results. The returned value type for COUNT is INTEGER, for MIN, MAX and AVG it is the same type as the column, for SOME and EVERY it is BOOLEAN. For VAR_POP, VAR_SAMP, STDDEV_POP and STDDEV_SAMP statistical functions, the type is always DOUBLE. These statistical functions do not allow ALL or DISTINCT qualifiers.

                If CROSS JOIN is specified no ON expression is allowed for the join.

                orderExpression
                { columnNr | columnAlias | selectExpression }
    [ASC | DESC]
                LIMIT n m

                Creates the result set for the SELECT statement first and then discards the first n rows (OFFSET) and returns the first m rows of the remaining result set (LIMIT). Special cases: LIMIT 0 m is equivalent to TOP m or FIRST m in other RDBMS's; LIMIT n 0 discards the first n rows and returns the rest of the result set.

                LIMIT m OFFSET n

                This form is used at the end of the SELECT statement. The OFFSET term is optional.

                TOP m

                Equivalent to LIMIT 0 m.

                UNION and other set operations

                Multiple SELECT statements joined with UNION, EXCEPT and INTERSECT are possible. Each SELECT is then treated as a term, and the set operation as an operator in an expression. The expression is evaluated from left to right but INTERSECT takes precedence over the rest of the operators and is applied first. You can use parentheses around any number of SELECT statements to change the evaluation order.

                See also: INSERT, UPDATE, DELETE.

                SET AUTOCOMMIT

                SET AUTOCOMMIT { TRUE | FALSE };

                Switches on or off the connection's auto-commit mode. If switched on, then all statements will be committed as individual transactions. Otherwise, the statements are grouped into transactions that are terminated by either COMMIT or ROLLBACK. By default, new connections are in auto-commit mode. This command should not be used directly. Use the JDBC equivalent method, Connection.setAutoCommit(boolean autocommit).

                SET DATABASE COLLATION[2]

                SET DATABASE COLLATION <double quoted collation name>;

                Each database can have its own collation. Sets the collation from the set of collations in the source for org.hsqldb.Collation.

                Once this command has been issued, the database can be opened in any JVM and will retain its collation.

                SET CHECKPOINT DEFRAG[2]

                SET CHECKPOINT DEFRAG <size>;

                The parameter size is the megabytes of abandoned space in the .data file. When a CHECKPOINT is performed either as a result of the .log file reaching the limit set by "SET LOGSIZE size", or by the user issuing a CHECKPOINT command, the amount of space abandoned during the session is checked and if it is larger than size, a CHECKPOINT DEFRAG is performed instead of a checkpoint.

                SET IGNORECASE

                SET IGNORECASE { TRUE | FALSE };

                Disables (ignorecase = true) or enables (ignorecase = false) the case sensitivity of text comparison and indexing for new tables. By default, character columns in new databases are case sensitive. The sensitivity must be switched before creating tables. Existing tables and their data are not affected. When switched on, the data type VARCHAR is set to VARCHAR_IGNORECASE in new tables. Alternatively, you can specify the VARCHAR_IGNORECASE type for the definition of individual columns. So it is possible to have some columns case sensitive and some not, even in the same table.

                Only an administrator may do this.

                SET INITIAL SCHEMA [2]

                Users may change their base default schema name with the comand 

                SET INITIAL SCHEMA <schemaname>;
                This is the schema which database object names will resolve to for the current user, unless overridden as explained in Schema object naming. For reasons of backwards compatibility, the initial schema value will not be persisted across database shutdowns until HSQLDB version 1.8.1. (I.e., INITIAL SCHEMA settings will be lost upon database shutdown with HSQLDB versions lower than version 1.8.1).

                SET LOGSIZE

                SET LOGSIZE <size>;

                Sets the maximum size in MB of the .log file. Default is 200 MB. The database will be closed and opened (just like using CHECKPOINT) if the .log file gets over this limit, and so the .log file will shrink. 0 means no limit.

                See also: CHECKPOINT.

                SET MAXROWS

                SET MAXROWS <maxwors>;

                Describe me!

                SET PASSWORD

                SET PASSWORD <password>;

                Changes the password of the currently connected user. Password must be double quotedEmpty password can be set using "".

                SET PROPERTY[2]

                SET PROPERTY <double quoted name> <value>;

                Sets a database property. Properties that can be set using this command are either boolean or integral and are listed in the Advanced Topics chapter.

                SET READONLY

                SET READONLY {TRUE|FALSE};

                Describe me!

                SET REFERENTIAL INTEGRITY

                SET REFERENTIAL_INTEGRITY { TRUE | FALSE };

                This commands enables / disables the referential integrity checking (foreign keys). Normally it should be switched on (this is the default) but when importing data (and the data is imported in the 'wrong' order) the checking can be switched off.

                Warning

                Note that when referential integrity is switched back on, no check is made that the changes to the data are consistent with the existing referential integrity constraints. You can verify consistency using SQL queries and take appropriate actions.

                Only an administrator may do this.

                See also: CREATE TABLE.

                SET SCHEMA[2]

                SET SCHEMA <schemaname>;

                Sets the current JDBC session's schema. The sole purpose for the session schema is to provide a default schema name for schema objects that do not have the schema name specified explicitly in the SQL command, or by association with another object of known schema. For example, if you run SELECT * FROM atbl;, HSQLDB will look for the table or view named atbl in the session's current schema.

                Session schemas last only for the duration of the current session. When a new JDBC session is obtained, the new session will have the default schema.

                SET SCRIPTFORMAT[2]

                SET SCRIPTFORMAT {TEXT | BINARY | COMPRESSED};

                Changes the format of the script file. BINARY and COMPRESSED formats are slightly faster and more compact than the default TEXT. Recommended only for very large script files.

                SET TABLE INDEX

                SET TABLE tableName INDEX 'index1rootPos index2rootPos ... ';

                This command is only used internally to store the position of index roots in the .data file. It appears only in database script files; it should not be used directly.

                SET TABLE READONLY[2]

                SET TABLE <tablename> READONLY {TRUE | FALSE};

                Sets the table as read only.

                SET TABLE SOURCE[2]

                SET TABLE <tablename> SOURCE <file and options> [DESC];

                For details see the Text Tables chapter.

                This command is used exclusively with TEXT tables to specify which file is used for storage of the data. The optional DESC qualifier results in the text file indexed from the end and opened as readonly. The <file and options> argument is a double quoted string that consists of:

                    <file and options>::= <doublequote> <filepath>
        [<semicolon> <option>...] <doublequote>

                Example:

                    SET TABLE mytable SOURCE "myfile;fs=|;vs=.;lvs=~"

                Supported Properties

                quoted = { true | false }

                default is true. If false, treats double quotes as normal characters

                all_quoted = { true | false }

                default is false. If true, adds double quotes around all fields.

                encoding = <encoding name>

                character encoding for text and character fields, for example, encoding=UTF-8

                ignore_first = { true | false }

                default is false. If true ignores the first line of the file

                cache_scale= <numeric value>

                exponent to calculate rows of the text file in cache. Default is 8, equivalent to nearly 800 rows

                cache_size_scale = <numeric value>r

                exponent to calculate average size of each row in cache. Default is 8, equivalent to 256 bytes per row.

                fs = <unquoted character>

                field separator

                vs = <unquoted character>

                varchar separator

                lvs = <unquoted character>

                long varchar separator

                Special indicators for Hsqldb Text Table separators

                \semi

                semicolon

                \quote

                quote

                SET WRITE DELAY[2]

                SET WRITE_DELAY {{ TRUE | FALSE } | <seconds> | <milliseconds> MILLIS};

                This controls the frequency of file sync for the log file. When WRITE_DELAY is set to FALSE or 0, the sync takes place immediately at each COMMIT. WRITE_DELAY TRUE performs the sync once every 20 seconds (which is the default). A numeric value can be specified instead.

                The purpose of this command is to control the amount of data loss in case of a total system crash. A delay of 1 second means at most the data written to disk during the last second before the crash is lost. All data written prior to this has been synced and should be recoverable.

                A write delay of 0 impacts performance in high load situations, as the engine has to wait for the file system to catch up.

                To avoid this, you can set write delay down to 10 milliseconds. In practice, a write delay of 100 milliseconds provides better than 99.9999% reliability with an average one system crash per day, or 99.99999% with an average one system crash per 6 days.

                Each time a SET WRITE_DELAY is issued with any value, a sync is immediately performed.

                Only an administrator may do this.

                SHUTDOWN

                SHUTDOWN [IMMEDIATELY | COMPACT | SCRIPT[2]];

                Closes the current database.

                Varieties of the SHUTDOWN command

                SHUTDOWN

                Performs a checkpoint to creates a new .script file that has the minimum size and contains the data for memory tables only. It then backs up the .data file containing the CACHED TABLE data in zipped format to the .backup file and closes the database.

                SHUTDOWN IMMEDIATELY

                Just closes the database files (like when the Java process for the database is terminated); this command is used in tests of the recovery mechanism. This command should not be used as the routine method of closing the database.

                SHUTDOWN COMPACT

                Writes out a new .script file which contains the data for all the tables, including CACHED and TEXT tables. It then deletes the existing text table files and the .data file before rewriting them. After this, it backs up the .data file in the same way as normal SHUTDOWN. This operation shrinks all files to the minimum size.

                SHUTDOWN SCRIPT

                Similar to SHUTDOWN COMPACT but after writing the script and deleting the existing files, it does not rewrite the .data and text table files. After SHUTDOWN SCRIPT, only the .script and .properties file remain. At the next startup, these files are processed and the .data and .backup files are created. This command in effect performs part of the job of SHUTDOWN COMPACT, leaving the other part to be performed automatically at the next startup.

                This command produces a full script of the database which can be edited for special purposes prior to the next startup.

                Only an administrator may use the SHUTDOWN command.

                UPDATE

                UPDATE table SET column = Expression [, ...] [WHERE Expression];

                Modifies data of a table in the database.

                See also: SELECT[2], INSERT, DELETE.

                Schema object naming

                Schema objects are database objects that are always scoped to a specific schema. Each schema has a namespace. There may be multiple schema objects of the same name, each in the namespace of a different schema. A particular schema object may nearly always be uniquely identified using the notation schemaname.objectname. All HSQLDB database objects are schema objects, other than the following.

                Users

                Roles

                Store Procedure Java Classes

                HSQL Aliases

                Our current Java-class-based Triggers are not fully schema objects. However, we are in the process of implementing SQL-conformant triggers which will encompass our Java-class-based triggers. When this work is completed, HSQLDB triggers will be schema objects.

                Sequences are schema objects with creation and removal permission governed by schema authorization (as described hereafter), but GRANT and REVOKE command do not work yet for sequences. In a future version of HSQLDB, sequence GRANTs and REVOKEs will work similarly to the current GRANT and REVOKE commands for table access.

                Most of the time, you do not need to specify the schema for the desired schema object, because the implicit schema is usually the only one that can be used. For example, when creating an index, the target schema will default to that of the table which is the target of the index. Named constraints are an extreme example of this. There is never a need to specify a schema name for a constraint, since constraint names are only specified in a CREATE or ALTER TABLE command, and the schema must be that of the target table. If the implicit schema is not determined by a related object, then the default comes from your JDBC session's current schema setting. The session schema value will be your login user's initial schema, or whatever you last set it to with SET SCHEMA[2] in your current JDBC session with the SET SCHEMA command. (Your initial schema is "PUBLIC" unless changed with the ALTER USER SET INITIAL SCHEMA or the SET INITIAL SCHEMA [2] command).

                In addition to namespace scoping, there are permission aspects to the schema of a database object. The authorization of a schema is a role or user that is basically the owner of the schema. Only a user with the DBA role (an admin user) or the owner of a schema may create objects, or modify the DDL of objects, in the namespace of that schema. In this way, a schema authorization is said to "own" the objects of that schema. A schema authorization/owner can be a role or a user (even a role with no members). The two schemas automatically created when a database is initialized are both owned by the role DBA.

                An important implication to database objects being owned by the schema owner is, if a non-DBA database user is to have permission to create any database object, they must have ownership of a schema. To allow a user to create (or modify DDL of) objects in their own personal schema, you would create a new schema with that user as the authorization. To allow a non-DBA user to share create and DDL privileges in some schema, you would create this schema with a role as the authorization, then GRANT this role to all of the desired users.

                The INFORMATION_SCHEMA is a system defined schema that contains the system tables for the database. This schema is read-only. When a database is created, a shema named PUBLIC is automatically created as the default schma. This schema has the authorization DBA. You can change the name of this schema. If all non-system schemas are dropped from a database, an empty PUBLIC schema is created again. So each database always has at least one non-system schema.

                LONGVARBINARYas Integer.MAXVALUEbyte[]
                OTHER | OBJECTas Integer.MAXVALUEjava.lang.Object

                The uppercase names are the data types names defined by the SQL standard or commonly used by RDMS's. The data types in quotes are the Java class names - if these type names are used then they must be enclosed in quotes because in Java names are case-sensitive. Range indicates the maximum size of the object that can be stored. Where Integer.MAXVALUE is stated, this is a theoretical limit and in practice the maximum size of a VARCHAR or BINARY object that can be stored is dictated by the amount of memory available. In practice, objects of up to a megabyte in size have been successfully used in production databases.

                The recommended Java mapping for the JDBC datatype FLOAT is as a Java type "double". Because of the potential confusion it is recommended that DOUBLE is used instead of FLOAT.

                VARCHAR_IGNORECASE is a special case-insensitive type of VARCHAR. This type is not portable.

                In table definition statements, HSQLDB accepts size, precision and scale qualifiers only for certain types: CHAR(s), VARCHAR(s), DOUBLE(p), NUMERIC(p), DECIMAL(p,s) and TIMESTAMP(p).

                TIMESTAMP(p) can take only 0 or 6 as precision. Zero indicates no subsecond part. Without the precision, the default is 6.

                By default specified precision and scale for the column is simply ignored by the engine. Instead, the values for the corresponding Java types are always used, which in the case of DECIMAL is an unlimited precision and scale. If a size is specified, it is stored in the database definition but is not enforeced by default. Once you have created the database (before adding data), you can add a database property value to enforce the sizes:

                    SET PROPERTY "sql.enforce_strict_size" true

                This will enforce the specified size and pad CHAR fields with spaces to fill the size. This complies with SQL standards by throwing an exception if an attempt is made to insert a string longer than the maximum size. It also results in all DECIMAL values conforming to the specified precision and scale.

                CHAR and VARCHAR and LONGVARCHAR columns are by default compared and sorted according to POSIX standards. See the SET DATABASE COLLATION[2] section above to modify this behavior. The property sql.compare_in_locale is no longer supported. Instead, you can define a collation to be used for all character comparisons.

                Columns of the type OTHER or OBJECT contain the serialized form of a Java Object in binary format. To insert or update such columns, a binary format string (see below under Expression) should be used. Using PreparedStatements with JDBC automates this transformation.

                SQL Comments

                -- SQL style line comment
                // Java style line comment

                Stored Procedures / Functions

                Stored procedures are static Java functions that are called directly from the SQL language or using an alias. Calling Java functions (directly or using the alias) requires that the Java class can be reached by the database (server). The syntax is:

                    "java.lang.Math.sqrt"(2.0)

                This means the package must be provided, and the name must be written as one word, and inside " because otherwise it is converted to uppercase (and not found).

                An alias can be created using the command CREATE ALIAS:

                    CREATE ALIAS SQRT FOR "java.lang.Math.sqrt";

                When an alias is defined, then the function can be called additionally using this alias:

                    SELECT SQRT(A) , B FROM MYTABLE;

                Only static java methods can be used as stored procedures. If, within the same class, there are overloaded methods with the same number of arguments, then the first one encountered by the program will be used. If you want to use Java library methods, it is recommended that you create your own class with static methods that act as wrappers around the Java library methods. This will allow you to control which method signature is used to call each Java library method.

                SQL Expression

                [NOT] condition [{ OR | AND } condition]

                Components of SQL Expressions

                condition
                   { value [|| value]
  | value { = | < | <= | > | >= | <> | != } value
  | value IS [NOT] NULL
  | EXISTS(selectStatement)
  | value BETWEEN value AND value
  | value [NOT] IN ( {value [, ...] | selectStatement } )
  | value [NOT] LIKE value [ESCAPE] value }
                value
                   [+ | -] { term [{ + | - | * | / | || } term]
  | ( condition )
  | function ( [parameter] [,...] )
  | selectStatement giving one value
  | {ANY|ALL} (selectStatement giving single column)
                term
                   { 'string' | number | floatingpoint
  | [table.]column | TRUE | FALSE | NULL }
                sequence
                   NEXT VALUE FOR <sequence>

                HSQLDB does not currently enforce the SQL 200n proposed rules on where sequence generated values are allowed to be used. In general, these values can be used in insert and update statements but not in CASE statements, order by clauses, search conditions, aggregate functions, or grouped queries.

                string

                Strings in HSQLDB are Unicode strings. A string starts and ends with a single ' (singlequote). In a string started with ' (singlequote) use '' (two singlequotes) to create a ' (singlequote).

                String contatenation should be performed with the standard SQL operator || rather than the non-standard + operator.

                The LIKE keyword uses '%' to match any (including 0) number of characters, and '_' to match exactly one character. To search for '%' or '_' itself an escape character must also be specified using the ESCAPE clause. For example, if the backslash is the escaping character, '\%' and '\_' can be used to find the '%' and '_' characters themselves. For example, SELECT .... LIKE '\_%' ESCAPE '\' will find the strings beginning with an underscore.

                name

                The character set for quoted identifiers (names) in HSQLDB is Unicode.

                A unquoted identifier (name) starts with a letter and is followed by any number of ASCII letters or digits. When an SQL statement is issued, any lowercase characters in unquoted identifiers are converted to uppercase. Because of this, unquoted names are in fact ALL UPPERCASE when used in SQL statements. An important implication of this is the for accessing columns names via JDBC DatabaseMetaData: the internal form, which is the ALL UPPERCASE must be used if the column name was not quoted in the CREATE TABLE statement.

                Quoted identifiers can be used as names (for tables, columns, constraints or indexes). Quoted identifiers start and end with " (one doublequote). A quoted identifier can contain any Unicode character, including space. In a quoted identifier use "" (two doublequotes) to create a " (one doublequote). With quoted identifiers it is possible to create mixed-case table and column names. Example:

                    CREATE TABLE "Address" ("Nr" INTEGER,"Name" VARCHAR);
    SELECT "Nr", "Name" FROM "Address";

                The equivalent quoted identifier can be used for an unquoted identifer by converting the identifier to all uppercase and quoting it. For example, if a table name is defined as Address2 (unquoted), it can be referred to by its quoted form, "ADDRESS2", as well as address2, aDDress2 and ADDRESS2. Quoted identifiers should not be confused with SQL strings.

                Quoting can sometimes be used for identifiers, aliases or functions when there is an ambiguity. For example:

                    SELECT COUNT(*) "COUNT" FROM MYTABLE;
    SELECT "LEFT"(COL1, 2) FROM MYTABLE;

                Although HSQLDB 1.8.0 does not force unquoted identifiers to contain only ASCII characters, the use of non-ASCII characters in these identifiers does not comply with SQL standards. Portability between different JRE locales could be an issue when accented characters (or extended unicode characters) are used in unquoted identifiers. Because native Java methods are used to convert the identifier to uppercase, the result may vary not be expected in different locales. It is recommended that accented characters are used only in quoted identifiers.

                When using JDBC DatabaseMetaData methods that take table, column, or index identifiers as arguments, treat the names as they are registered in the database. With these methods, unquoted identifiers should be used in all-uppercase to get the correct result. Quoted identifiers should be used in the exact case combination as they were defined - no quote character should be included around the name. JDBC methods that return a result set containing such identifiers return unquoted identifiers as all-uppercase and quoted identifiers in the exact case they are registered in the database (a change from 1.6.1 and previous versions).

                Please also note that the JDBC getXXX(String columnName) methods interpret the columnName as case-independent. This is a general feature of JDBC and not specific to HSQLDB.

                password

                Passwords must be double quoted and used consistently. Passwords are case insensitive only for backward compatibility. This may change in future versions.

                values

                • A DATE literal starts and ends with ' (singlequote), the format is yyyy-mm-dd (see java.sql.Date.

                • A TIME liteal starts and ends with ' (singlequote), the format is hh:mm:ss (see java.sql.Time).

                • A TIMESTAMP or DATETIME literal starts and ends with ' (singlequote), the format is yyyy-mm-dd hh:mm:ss.SSSSSSSSS (see java.sql.Timestamp).

                When specifying default values for date / time columns in CREATE TABLE statements, or in SELECT,INSERT, and UPDATE statements, special SQL functions: NOW, SYSDATE, TODAY, CURRENT_TIMESTAMP, CURRENT_TIME and CURRENT_DATE (case independent) can be used. NOW is used for TIME and TIMESTAMP columns, TODAY is used for DATE columns. The data and time variants CURRENT_* are SQL standard versions and should be used in preference to others. Example:

                    CREATE TABLE T(D DATE DEFAULT CURRENT_DATE);
    CREATE TABLE T1(TS TIMESTAMP DEFAULT CURRENT_TIMESTAMP);

                Binary data starts and ends with ' (singlequote), the format is hexadecimal. '0004ff' for example is 3 bytes, first 0, second 4 and last 255 (0xff).

                Any number of commands may be combined. With combined commands, ';' (semicolon) must be used at the end of each command to ensure data integrity, despite the fact that the engine may understand the end of commands and not return an error when a semicolon is not used.


                [2] These features were added by HSQL Development Group since April 2001

                Purpose, Coverage, Changes in Behavior

                This document explains how to use SqlTool, the main purpose of which is to read your SQL text file or stdin, and execute the SQL commands therein against a JDBC database. There are also a great number of features to facilitate both interactive use and automation. The following paragraphs explain in a general way why SqlTool is better than any existing tool for text-mode interactive SQL work, and for automated SQL tasks. Two important benefits which SqlTool shares with other pure Java JDBC tools is that users can use a consistent interface and syntax to interact with a huge variety of databases-- any database which supports JDBC; plus the tool itself runs on any Java platform. Instead of using isql for Sybase, psql for Postgresql, Sql*plus for Oracle, etc., you can use SqlTool for all of them. As far as I know, SqlTool is the only production-ready, pure Java, command-line, generic JDBC client. Several databases come with a command-line client with limited JDBC abilities (usually designed for use with their specific database).

                SqlTool is purposefully not a Gui tool like Toad or DatabaseManager. There are many use cases where a Gui SQL tool would be better. Where automation is involved in any way, you really need a text client to at least test things properly and usually to prototype and try things out. A command-line tool is really better for executing SQL scripts, any form of automation, direct-to-file fetching, and remote client usage. To clarify this last, if you have to do your SQL client work on a work server on the other side of a VPN connection, you will quickly appreciate the speed difference between text data transmission and graphical data transmission, even if using VNC or Remote Console. Another case would be where you are doing some repetitive or very structured work where variables or language features would be useful. Gui proponents may disagree with me, but scripting (of any sort) is more efficient than repetitive copy & pasting with a Gui editor. SqlTool starts up very quickly, and it takes up a tiny fraction of the RAM required to run a comparably complex Gui like Toad.

                SqlTool is superior for interactive use because over many years it has evolved lots of features proven to be efficient for day-to-day use. Three concise help commands (\?, :?, and *?) list all available commands of the corresponding type. SqlTool doesn't support up-arrow or other OOB escapes (due to basic Java I/O limitations), but it more than makes up for this limitation with aliases, user variables, command-line history and recall, and command-line editing with extended Perl/Java regular expressions. The \d commands deliver JDBC metadata information as consistently as possible (in several cases, database-specific work-arounds are used to obtain the underlying data even though the database doesn't provide metadata according to the JDBC specs). Unlike server-side language features, the same feature set works for any database server. Database access details may be supplied on the command line, but day-to-day users will want to centralize JDBC connection details into a single, protected RC file. You can put connection details (username, password, URL, and other optional settings) for scores of target databases into your RC file, then connect to any of them whenever you want by just giving SqlTool the ID ("urlid") for that database. When you Execute SqlTool interactively, it behaves by default exactly as you would want it to. If errors occur, you are given specific error messages and you can decide whether to roll back your session. You can easily change this behavior to auto-commit, exit-upon-error, etc., for the current session or for all interactive invocations. You can import or export delimiter-separated-value files.

                When you Execute SqlTool with a SQL script, it behaves by default exactly as you would want it to. If any error is encountered, the connection will be rolled back, then SqlTool will exit with an error exit value. If you wish, you can detect and handle error (or other) conditions yourself. For scripts expected to produce errors (like many scripts provided by database vendors), you can have SqlTool continue-upon-error. For SQL script-writers, you will have access to portable scripting features which you've had to live without until now. You can use variables set on the command line or in your script. You can handle specific errors based on the output of SQL commands or of your variables. You can chain SQL scripts, invoke external programs, dump data to files, use prepared statements, Finally, you have a procedural language with if, foreach, while, continue, and break statements.

                Platforms and SqlTool versions covered

                SqlTool runs on any Java 1.4 or later platform. I haven't run it with a non-Sun JVM in years (like Blackdown, IBM, JRockit, etc.), but I've had no reports of problems with them, and SqlTool uses none of the Sun-proprietary classes directly. Some of the examples below use quoting which works exactly as-is for any Bourne-compatible UNIX shell. (Only line-continuation would need to be changed for C-compatible UNIX shells). I have not yet tested these commands on Windows, and I doubt whether the quoting will work just like this (though it is possible). SqlTool is still a very useful tool even if you have no quoting capability at all.

                If you are using SqlTool from a HSQLDB distribution before version 1.8.0.8 final, you should use the documentation with that distribution, because this manual documents many new features, several significant changes to interactive-only commands, and a few changes effecting backwards-compatibility (see next section about that). This document is now updated for the current versions of SqlTool and SqlFile at the time I am writing this (versions 333 and 354 correspondingly, SqlFile is the class which does most of the work for SqlTool). Therefore, if you are using a version of SqlTool or SqlFile that is more than a couple revisions greater, you should find a newer version of this document. (The imprecision is due to content-independent revision increments at build time, and the likelihood of one or two behavior-independent bug fixes after public releases). The startup banner will report both versions when you run SqlTool interactively. (Dotted version numbers of SqlTool and SqlFile are older than 333 and 354).

                This guide covers SqlTool bundled with series 1.8 and 1.9 of HSQLDB. [1]

                Functional Changes

                This section lists changes to SqlTool since the last major release of HSQLDB which may effect the portability of SQL scripts. For this revision of this document, this list consists of script-impacting changes made to SqlTool after the final 1.8.0.0 HSQLDB release. I'm specifically not listing changes to interactive-only commands (":" commands, with one legacy exception which is listed below), since these commands can't be used in SQL scripts; and I'm specifically not listing backwards-compatible feature additions and enhancements. The reason for limiting the change list to only portability- impacting changes is that a list of all enhancements since just 1.8.0.0 would be pages long.

                • SqlTool now consistently outputs \r\n line breaks when on \r\n-linebreak platforms, like Windows. This includes output written to stdout, \w files, and \o files.
                • Time type values are always output with the date as well as the time. This was required in order to produce consistent output for the wildly varying formats provided by different database vendors.
                • DSV input now takes JDBC Timestamp format with date and optionally time of day.
                • The command ":;" is now strictly an interactive command. If you want to repeat a command in an SQL scripts, just repeat the exact text of the command. Non-interactive use now has no dependency on command history.
                • The command ":w" has replace the command \w. Unlike writing "output" to a file with \w, :w is used to write SQL "commands", and this is an interactive feature.
                • Shell scripts using raw mode (e.g. PL/SQL scripts) must terminate the raw code with a line containing ".;", which will also send the code to the database for execution. (The old "." command has been changed to ":." to make it very clear that the command is now an interactive command).
                • The --sql argument will never automatically append a semicolon to the text you provide. If you want to execute a command ending with a semi-- then type a semi.

                Although it doesn't effect scripts, I will mention a significant recent change to interactive commands. Special and PL commands are not stored to the edit buffer and to command history, so they can be recalled and edited just like SQL commands. Now, only edit/history : commands are not stored to the buffer and history.

                The Bare Minimum You Need to Know to Run SqlTool

                Warning

                If you are using an Oracle database server, it will commit your current transaction if you cleanly disconnect, regardless of whether you have set auto-commit or not. This will occur if you exit SqlTool (or any other client) in the normal way (as opposed to killing the process or using Ctrl-C, etc.). This is mentioned in this section only for brevity, so I don't need to mention it in the main text in the many places where auto-commit is discussed. This behavior has nothing to do with SqlTool. It is a quirk of Oracle.

                If you want to use SqlTool, then you either have an SQL text file, or you want to interactively type in SQL commands. If neither case applies to you, then you are looking at the wrong program.

                Procedure 8.1. To run SqlTool...

                1. Copy the file sqltool.rc from the directory sample [1] of your HSQLDB distribution to your home directory and secure access to it if your computer is accessible to anybody else (most likely from the network). This file will work as-is for a Memory Only database instance; or if your target is a HSQLDB Server running on your local computer with default settings and the password for the "sa" account is blank (the sa password is blank when new HSQLDB database instances are created). Edit the file if you need to change the target Server URL, username, password, character set, JDBC driver, or TLS trust store as documented in the RC File Authentication Setup section. (You could, alternatively, use the --inlineRc command-line switch to specify your connection parameters as documented in the Using Inline RC Authentication section).

                2. Find out where your hsqldb.jar file resides. It typically resides at HSQLDB_HOME/lib/hsqldb.jar where HSQLDB_HOME is the base directory of your HSQLDB software installation. For this reason, I'm going to use "$HSQLDB_HOME/lib/hsqldb.jar" as the path to hsqldb.jar for my examples, but understand that you need to use the actual path to your own hsqldb.jar file.

                3. Run 

                      java -jar $HSQLDB_HOME/lib/hsqldb.jar --help
                  to see what command-line arguments are available. Note that you don't need to worry about setting the CLASSPATH when you use the -jar switch to java. Assuming that you set up your SqlTool RC file at the default location and you want to use the HSQLDB JDBC driver, you will want to run something like 
                      java -jar $HSQLDB_HOME/lib/hsqldb.jar mem
                  for interactive use, or 
                      java -jar $HSQLDB_HOME/lib/hsqldb.jar --sql 'SQL statement;' mem
                  or 
                      java -jar $HSQLDB_HOME/lib/hsqldb.jar mem filepath1.sql...
                  where mem is an urlid, and the following arguments are paths to text SQL files. For the filepaths, you can use whatever wildcards your operating system shell supports.

                  The urlid mem in these commands is a key into your RC file, as explained in the RC File Authentication Setup section. Since this is a Memory Only database, you can use SqlTool with this urlid immediately with no database setup whatsoever (however, you can't persist any changes that you make to this database). The sample sqltool.rc file also defines the urlid "localhost-sa" for a local HSQLDB Server. At the end of this section, I explain how you can load some sample data to play with, if you want to.

                Important

                SqlTool does not commit SQL changes by default. This leaves it to the user's disgression whether to commit or rollback their modifications. Remember to either run \= to commit before quitting SqlTool (most databases also support the SQL command commit;, or use the --autoCommit command-line switch.

                If you put a file named auto.sql into your home directory, this file will be executed automatically every time that you run SqlTool interactively and without the --noAutoFile switch.

                To use a JDBC Driver other than the HSQLDB driver, you can't use the -jar switch because you need to modify the classpath. You must add the hsqldb.jar file and your JDBC driver classes to your classpath, and you must tell SqlTool what the JDBC driver class name is. The latter can be accomplished by either using the "--driver" switch, or setting "driver" in your config file. The RC File Authentication Setup section. explains the second method. Here's an example of the first method (after you have set the classpath appropriately). 

                java org.hsqldb.util.SqlTool --driver oracle.jdbc.OracleDriver urlid

                Tip

                If the tables of query output on your screen are all messy because of lines wrapping, the best and easiest solution is usually to resize your terminal emulator window to make it wider. (With some terms you click & drag the frame edges to resize, with others you use a menu system where you can enter the number of columns).

                If you are using SqlTool to connect to a HSQLDB network server or any non-HSQLDB database, you may prefer to use the jar file hsqltool.jar or hsqldbutil.jar instead of hsqldb.jar. These alternative jar files contain all of SqlTool without stuff you don't need, but you will have to follow a simple procedure to generate these jars. See the Using hsqltool.jar and hsqldbutil.jar section.

                Non-displayable Types

                There are many SQL types which SqlTool (being a text-based program) can't display properly. This includes the SQL types BLOB, JAVA_OBJECT, STRUCT, and OTHER. When you run a query that returns any of these, SqlTool will save the very first such value obtained to the binary buffer and will not display any output from this query. You can then save the binary value to a file, as explained in the Storing and retrieving binary files section.

                There are other types, such as BINARY, which JDBC can make displayable (by using ResultSet.getString()), but which you may very well want to retrieve in raw binary format. You can use the \b command to retrieve any-column-type-at-all in raw binary format (so you can later store the value to a binary file).

                Another restriction which all text-based database clients have is the practical inability for the user to type in binary data such as photos, audio streams, and serialized Java objects. You can use SqlTool to load any binary object into a database by telling SqlTool to get the insert/update datum from a file. This is also explained in the Storing and retrieving binary files section.

                Desktop shortcuts

                Desktop shortcuts and quick launch icons are useful, especially if you often run SqlTool with the same set of arguments. It's really easy to set up several of them-- one for each way that you invoke SqlTool (i.e., each one would start SqlTool with all the arguments for one of your typical startup needs). One typical setup is to have one shortcut for each database account which you normally use (use a different urlid argument in each shortcut's Target specification.

                Desktop icon setup varies depending on your Desktop manager, of course. I'll explain how to set up a SqlTool startup icon in Windows XP. Linux and Mac users should be able to take it from there, since it's easier with the common Linux and Mac desktops.

                Procedure 8.2. Creating a Desktop Shortcut for SqlTool

                1. Right click in the main Windows background.

                2. New

                3. Shortcut

                4. Browse

                5. Navigate to where your good JRE lives. For recent Sun JRE's, it installs to C:\Program Files\Java\*\bin by default (the * will be a JDK or JRE name and version number).

                6. Select java.exe.

                7. OK

                8. Next

                9. Enter any name

                10. Finish

                11. Right click the new icon.

                12. Properties

                13. Edit the Target field.

                14. Leave the path to java.exe exactly as it is, including the quotes, but append to what is there. Beginning with a space, enter the command-line that you want run.

                15. Change Icon... to a pretty icon.

                16. If you want a quick-launch icon instead of (or in addition to) a desktop shortcut icon, click and drag it to your quick launch bar. (You may or may not need to edit the Windows Toolbar properties to let you add new items).

                Loading sample data

                If you want some sample database objects and data to play with, execute the sampledata.sql SQL file. sampledata.sql resides in the sample directory of your HSQLDB distribution [1]. To separate the sample data from your regular data, you can put it into its own schema by running this before you import: 

                    CREATE SCHEMA sampledata AUTHORIZATION dba;
    SET SCHEMA sampledata;
                Run it like this from an SqlTool session 
                \i HSQLDB_HOME/sample/sampledata.sql
                where HSQLDB_HOME is the base directory of your HSQLDB software installation [1].

                For memory-only databases, you'll need to run this every time that you run SqlTool. For other (persistent) databases, the data will reside in your database until you drop the tables.

                RC File Authentication Setup

                RC file authentication setup is accomplished by creating a text RC configuration file. In this section, when I say configuration or config file, I mean an RC configuration file. RC files can be used by any JDBC client program that uses the org.hsqldb.util.RCData class-- this includes SqlTool, DatabaseManager, DatabaseManagerSwing. You can use it for your own JDBC client programs too.

                The following sample RC file resides at sample/sqltool.rc in your HSQLDB distribution [1].

                Example 8.1. Sample RC File

                # $Id: sqltool.rc,v 1.22 2007/08/09 03:22:21 unsaved Exp $

# This is a sample RC configuration file used by SqlTool, DatabaseManager,
# and any other program that uses the org.hsqldb.util.RCData class.

# You can run SqlTool right now by copying this file to your home directory
# and running
#    java -jar /path/to/hsqldb.jar mem
# This will access the first urlid definition below in order to use a 
# personal Memory-Only database.
# "url" values may, of course, contain JDBC connection properties, delimited
# with semicolons.

# If you have the least concerns about security, then secure access to
# your RC file.
# See the documentation for SqlTool for various ways to use this file.

# A personal Memory-Only (non-persistent) database.
urlid mem
url jdbc:hsqldb:mem:memdbid
username sa
password

# A personal, local, persistent database.
urlid personal
url jdbc:hsqldb:file:${user.home}/db/personal;shutdown=true
username sa
password
# When connecting directly to a file database like this, you should 
# use the shutdown connection property like this to shut down the DB
# properly when you exit the JVM.

# This is for a hsqldb Server running with default settings on your local
# computer (and for which you have not changed the password for "sa").
urlid localhost-sa
url jdbc:hsqldb:hsql://localhost
username sa
password



# Template for a urlid for an Oracle database.
# You will need to put the oracle.jdbc.OracleDriver class into your 
# classpath.
# In the great majority of cases, you want to use the file classes12.zip
# (which you can get from the directory $ORACLE_HOME/jdbc/lib of any
# Oracle installation compatible with your server).
# Since you need to add to the classpath, you can't invoke SqlTool with
# the jar switch, like "java -jar .../hsqldb.jar..." or 
# "java -jar .../hsqlsqltool.jar...".
# Put both the HSQLDB jar and classes12.zip in your classpath (and export!)
# and run something like "java org.hsqldb.util.SqlTool...".

#urlid cardiff2

# Template for a TLS-encrypted HSQLDB Server.
# Remember that the hostname in hsqls (and https) JDBC URLs must match the
# CN of the server certificate (the port and instance alias that follows 
# are not part of the certificate at all).
# You only need to set "truststore" if the server cert is not approved by
# your system default truststore (which a commercial certificate probably
# would be).

# Template for a Microsoft SQL Server database
#urlid msprojsvr

# The SelectMethod setting is required to do more than one thing on a JDBC

# This is for Microsoft's SQL Server 2000 driver (requires mssqlserver.jar
# and msutil.jar).

# Template for a Sybase database
#urlid sybase
#url jdbc:sybase:Tds:hostname:4100/dbname
#username blaine
#password hiddenpwd
# This is for the jConnect driver (requires jconn3.jar).
#driver com.sybase.jdbc3.jdbc.SybDriver

# Template for Embedded Derby / Java DB.
#urlid derby1
#url jdbc:derby:path/to/derby/directory;create=true
#username ${user.name}
#password any_noauthbydefault
#driver org.apache.derby.jdbc.EmbeddedDriver
# The embedded Derby driver requires derby.jar.
# There'a also the org.apache.derby.jdbc.ClientDriver driver with URL
# like jdbc:derby://<server>[:<port>]/databaseName, which requires
# derbyclient.jar.
# You can use \= to commit, since the Derby team decided (why???)
# not to implement the SQL standard statement "commit"!!
# Note that SqlTool can not shut down an embedded Derby database properly,
# since that requires an additional SQL connection just for that purpose.
# However, I've never lost data by not shutting it down properly.
# Other than not supporting this quirk of Derby, SqlTool is miles ahead of ij.

                You can put this file anywhere you want to, and specify the location to SqlTool/DatabaseManager/DatabaseManagerSwing by using the --rcfile argument. If there is no reason to not use the default location (and there are situations where you would not want to), then use the default location and you won't have to give --rcfile arguments to SqlTool/DatabaseManager/DatabaseManagerSwing. The default location is sqltool.rc or dbmanager.rc in your home directory (corresponding to the program using it). If you have any doubt about where your home directory is, just run SqlTool with a phony urlid and it will tell you where it expects the configuration file to be. 

                    java -jar $HSQLDB_HOME/lib/hsqldb.jar x

                The config file consists of stanza(s) like this: 

                    urlid web
    url jdbc:hsqldb:hsql://localhost
    username web
    password webspassword

                These four settings are required for every urlid. (There are optional settings also, which are described a couple paragraphs down). The URL may contain JDBC connection properties. You can have as many blank lines and comments like 

                    # This comment

                in the file as you like. The whole point is that the urlid that you give in your SqlTool/DatabaseManager command must match a urlid in your configuration file.

                Important

                Use whatever facilities are at your disposal to protect your configuration file.

                It should be readable, both locally and remotely, only to users who run programs that need it. On UNIX, this is easily accomplished by using chmod/chown commands and making sure that it is protected from anonymous remote access (like via NFS, FTP or Samba).

                You can also put the following optional settings into a urlid stanza. The setting will, of course, only apply to that urlid.

                charset
                This is used by the SqlTool program, but not by the DatabaseManager programs. See the Character Encoding section of the Non-Interactive section. You can, alternatively, set this for one SqlTool invocation by setting the system property sqlfile.charset . Defaults to US-ASCII.
                driver
                Sets the JDBC driver class name. You can, alternatively, set this for one SqlTool/DatabaseManager invocation by using the command line switch --driver. Defaults to org.hsqldb.jdbcDriver.
                truststore
                TLS trust keystore store file path as documented in the TLS chapter. You usually only need to set this if the server is using a non-publicly-certified certificate (like a self-signed self-ca'd cert).

                Property and SqlTool command-line switches override settings made in the configuration file.

                Using Inline RC Authentication

                Inline RC authentication setup is accomplished by using the --inlineRc command-line switch on SqlTool. The --inlineRc command-line switch takes a comma-separated list of key/value elements. The url and user elements are required. The rest are optional.

                url
                The JDBC URL of the database you wish to connect to.
                user
                The username to connect to the database as.
                charset
                Sets the character encoding. Defaults to US-ASCII.
                trust
                The TLS trust keystore file path as documented in the TLS chapter.
                password
                You may only use this element to set empty password, like 
                                    password=
                . For any other password value, omit the password element and you will be prompted for the value.

                (Use the --driver switch instead of --inlineRc to specify a JDBC driver class). Here is an example of invoking SqlTool to connect to a standalone database. 

                    java -jar $HSQLDB_HOME/lib/hsqldb.jar
         --inlineRc URL=jdbc:hsqldb:file:/home/dan/dandb,USER=dan

                For security reasons, you cannot specify a non-empty password as an argument. You will be prompted for a password as part of the login process.

                Using the current version of SqlTool with an older HSQLDB distribution.

                This procedure will allow users of a legacy version of HSQLDB to use all of the new features of SqlTool. You will also get the new versions of the DatabaseManagers! This procedure works for distros going back to 1.7.3.3 at least, probably much farther.

                Follow the instructions in the See the Using hsqltool.jar and hsqldbutil.jar section to build the jar file hsqldbutil.jar.

                For now on, whenever you are going to run SqlTool, make sure that you have this hsqldbutil.jar as the first item in your CLASSPATH. You can't run SqlTool with the "-jar" switch (because the -jar switch doesn't permit setting your own class path).

                Here's a UNIX example where somebody wants to use the new SqlTool with their older HSQLDB database, as well as with Postgresql and a local application. 

                CLASSPATH=/path/to/hsqldbutil.jar:/home/bob/classes:/usr/local/lib/pg.jdbc3.jar
export CLASSPATH
java org.hsqldb.util.SqlTool urlid

                Interactive Usage

                Do read the The Bare Minimum section before you read this section.

                You run SqlTool interactively by specifying no SQL filepaths on the SqlTool command line. Like this. 

                    java -jar $HSQLDB_HOME/lib/hsqldb.jar urlid

                Procedure 8.3. What happens when SqlTool is run interactively (using all default settings)

                1. SqlTool starts up and connects to the specified database, using your SqlTool configuration file (as explained in the RC File Authentication Setup section).

                2. SQL file auto.sql in your home directory is executed (if there is one),

                3. SqlTool displays a banner showing the SqlTool and SqlFile version numbers and describes the different command types that you can give, as well as commands to list all of the specific commands available to you.

                You exit your session by using the "\q" special command or ending input (like with Ctrl-D or Ctrl-Z).

                Important

                Every command (regardless of type) and comment must begin at the beginning of a line (or immediately after a comment ends with "*/").

                You can't nest commands or comments. You can only start new commands (and comments) after the preceding statement has been terminated. (Remember that if you're running SqlTool interactively, you can terminate an SQL statement without executing it by entering a blank line).

                (Special Commands, Edit Buffer Commands and PL Commands always consist of just one line. Any of these commands or comments may be preceded by space characters.)

                These rules do not apply at all to Raw Mode. Raw mode is for use by advanced users when they want to completely bypass SqlTool processing in order to enter a chunk of text for direct transmission to the database engine.

                Command Types

                When you are typing into SqlTool, you are always typing part of the immediate command. You execute the immediate command by hitting ENTER after a semi-colon (for SQL commands) or by just hitting ENTER (after any other non-empty command-- see next section about this distinction). The interactive : commands can perform actions with or on the edit buffer. The edit buffer usually contains a copy of the last command executed, and you can always view it with the :b command. If you never use any : commands, you can entirely ignore the edit buffer. If you want to repeat commands or edit previous commands, you will need to work with the edit buffer. The immediate command contains whatever (and exactly what) you type. The command history and edit buffer may contain any type of command other than comments and : commands (i.e., : commands and comments are just not copied to the history or to the edit buffer).

                Hopefully an example will clarify the difference between the immediate command and the edit buffer. If you type in the edit buffer Substitution command ":s/tbl/table/", the :s command that you typed is the immediate command (and it will never be stored to the edit buffer or history, since it is a : command), but the purpose of the substitution command is to modify the contents of the edit buffer (perform a substitution on it)-- the goal being that after your substitutions you would execute the buffer with the ":;" command. The ":a" command is special in that when you hit ENTER to execute it, it copies the contents of the edit buffer to a new immediate command and leaves you in a state where you are appending to that immediate command (nearly) exactly as if you had just typed it in.

                Command Types

                Command types

                Note

                Above, we said that if you enter an SQL command, one SQL command corresponds to one SqlTool command. This is the most typical usage, however, you can actually put multiple SQL statements into one SQL command. One example would be 

                    INSERT INTO t1 VALUES(0); SELECT * FROM t1;
                This is one SqlTool command containing two SQL statements. See the Chunking section to see why you may want to chunk SQL commands, how, and the implications.

                SQL Statement

                Any command that you enter which does not begin with "\", ":", or "* " is an SQL Statement. The command is not terminated when you hit ENTER, like most OS shells. You terminate SQL Statements with either ";" at the end of a line, or with a blank line. In the former case, the SQL Statement will be executed against the SQL database and the command will go into the edit buffer and SQL command history for editing or viewing later on. In the former case, execute against the SQL database means to transmit the SQL text to the database engine for execution. In the latter case (you end an SQL Statement with a blank line), the command will go to the edit buffer and SQL history, but will not be executed (but you can execute it later from the edit buffer). (See the note immediately above about multiple SQL statements in one SqlTool command).

                (Blank lines are only interpreted this way when SqlTool is run interactively. In SQL files, blank lines inside of SQL statements remain part of the SQL statement).

                As a result of these termination rules, whenever you are entering text that is not a Special Command, Edit Buffer / History Command, or PL Command, you are always appending lines to an SQL Statement or comment. (In the case of the first line, you will be appending to an empty SQL statement. I.e. you will be starting a new SQL Statement or comment).

                Special Command
                Run the command "\?" to list the Special Commands. All of the Special Commands begin with "\". I'll describe some of the most useful Special Commands below.
                Edit Buffer / History Command
                Run the command ":?" to list the Edit-Buffer/History Commands. All of these commands begin with ":". These commands use commands from the command history, or operate upon the edit "buffer", so that you can edit and/or (re-)execute previously entered commands.
                PL Command

                Procedural Langage commands. Run the command "*?" to list the PL Commands. All of the PL Commands begin with "*". PL commands are for setting and using scripting variables and conditional and flow control statements like * if and * while. A few PL features (such as PL aliases and updating and selecing data directly from/to files) can be a real convenience for nearly all users, so these features will be discussed briefly in this section. More detailed explanation of PL variables and the other PL features, with examples, are covered in the SqlTool Procedural Language section.

                Raw Mode
                The descriptions of command-types above do not apply to Raw Mode. In raw mode, SqlTool doesn't interpret what you type at all. It all just goes into the edit buffer which you can send to the database engine. Beginners can safely ignore raw mode. You will never encounter it unless you run the "\." special command, or enter a PL/SQL command. See the Raw Mode section for the details.

                Special Commands

                Essential Special Commands

                \?
                help
                \q
                quit
                \i path/to/script.sql
                execute the specified SQL script, then continue again interactively.
                \=
                commit the current SQL transaction. Most users are used to typing the SQL statement commit;, but this command is crucial for those databases which don't support the statement. It's obviously unnecessary if you have auto-commit mode on.
                \x?
                List a summary of DSV eXporting, and all available DSV options.
                \m?
                List a summary of DSV iMporting, and all available DSV options.
                \d?
                List a summary of the \d commands below.
                \dt [filter_substring]
                \dv [filter_substring]
                \ds [filter_substring]
                \di [table_name]
                \dS [filter_substring]
                \da [filter_substring]
                \dn [filter_substring]
                \du [filter_substring]
                \dr [filter_substring]
                \d* [filter_substring]

                Lists available objects of the given type.

                • t: non-system Tables
                • v: Views
                • s: Sequences
                • i: Indexes
                • S: System tables
                • a: Aliases
                • n: schema Names
                • u: database Users
                • r: Roles
                • *: all table-like objects
                If your database supports schemas, then the schema name will also be listed.

                If you supply an optional filter substring, then only items which contain the given substring (in the object name or schema name) will be listed.

                Important

                The substring test is case-sensitive! Even though in SQL queries and for the "\d objectname" command object names are usually case-insensitive, for the \dX commands, you must capitalize the filter substring exactly as it will appear in the special command output. This is an inconvenience, since the database engine will change names in SQL to default case unless you double-quote the name, but that is server-side functionality which cannot (portably) be reproduced by SqlTool. You can use spaces and other special characters in the string.

                Tip

                Filter substrings ending with "." are special. If a substring ends with ".", then this means to narrow the search by the exact, case-sensitive schema name given. For example, if I run "\d* BLAINE.", this will list all table-like database objects in the "BLAINE" schema. The capitalization of the schema must be exactly the same as how the schema name is listed by the "\dn" command. You can use spaces and other special characters in the string. (I.e., enter the name exactly how you would enter it inside of double-quotes in an SQL command). This is an inconvenience, since the database engine will change names in SQL to default case unless you double-quote the name, but that is server-side functionality which cannot (portably) be reproduced by SqlTool.

                Important

                Indexes may not be searched for by substring, only by exact target table name. So if I1 is an index on table T1, then you list this index by running "\di T1". In addition, many database vendors will report on indexes only if a target table is identified. Therefore, "\di" with no argument will fail if your database vendor does not support it.

                \d objectname [filter]

                Lists names of columns in the specified table or view. objectname may be a base table name or a schema.object name.

                If you supply a filter string, then only columns with a name containing the given filter will be listed. The objectname is nearly always case-insensitive (depends on your database), but the filter is always case-sensitive. You'll find this filter is a great convenience compared to other database utilities, where you have to list all columns of large tables when you are only interested in one of them.

                Tip

                When working with real data (as opposed to learning or playing), I often find it useful to run two SqlTool sessions in two side-by-side terminal emulator windows. I do all of my real work in one window, and use the other mostly for \d commands. This way I can refer to the data dictionary while writing SQL commands, without having to scroll.

                This list here includes only the essential Special Commands, but n.b. that there are other useful Special Commands which you can list by running \?. (You can, for example, execute SQL from external SQL files, and save your interactive SQL commands to files). Some specifics of these other commands are specified immediately below, and the Generating Text or HTML Reports section explains how to use the "\o" and "\H" special commands to generate reports.

                Be aware that the \! Special Command does not work for external programs that read from standard input. You can invoke non-interactive and graphical interactive programs, but not command-line interactive programs.

                SqlTool executes \! programs directly, it does not run an operating system shell (this is to avoid OS-specific code in SqlTool). Because of this, you can give as many command-line arguments as you wish, but you can't use shell wildcards or redirection.

                The \w command can be used to store any command in your SQL history to a file. Just restore the command to the edit buffer with a command like "\-4" before you give the \w command.

                Edit Buffer / History Commands

                Edit Buffer / History Commands

                :?
                help
                :b
                List the current contents of the edit buffer.
                :h
                Shows the Command History. For each command which has been executed (up to the max history length), the SQL command history will show the command; its command number (#); and also how many commands back it is (as a negative number). : commands are never added to the history list. You can then use either form of the command identifier to recall a command to the edit buffer (the command described next) or as the target of any of the following : commands. This last is accomplished in a manner very similar to the vi editor. You specify the target command number between the colon and the command. As an example, if you gave the command :s/X/Y/, that would perform the substitution on the contents of the edit buffer; but if you gave the command :-3 s/X/Y/, that would perform the substitution on the command 3 back in the command history (and copy the output to the edit buffer). Also, just like vi, you can identify the command to recall by using a regular expression inside of slashes, like :/blue/ s/X/Y/ to operate on the last command you ran which contains "blue".
                :13 OR :-2 OR :/blue/

                Recalls a command from Command history to the edit buffer. Enter ":" followed by the positive command number from Command history, like ":13"... or ":" followed by a negative number like ":-2" for two commands back in the Command history... or ":" followed by a regular expression inside slashes, like ":/blue/" to recall the last command which contains "blue". The specified command will be written to the edit buffer so that you can execute it or edit it using the commands below.

                As described under the :h command immediately above, you can follow the command number here with any of the commands below to perform the given operation on the specified command from history instead of on the edit buffer contents. So, for example, ":4;" would load command 4 from history then execute it (see the ":;" command below).

                :;
                Executes the SQL, Special or PL statement in the edit buffer (by default). This is an extremely useful command. It's easy to remember because it consists of ":", meaning Edit Buffer Command, plus a line-terminating ";", (which generally means to execute an SQL statement, though in this case it will also execute a special or PL command).
                :a

                Enter append mode with the contents of the edit buffer (by default) as the current command. When you hit ENTER, things will be exactly as if you physically re-typed the command that is in the edit buffer. Whatever lines you type next will be appended to the immediate command. As always, you then have the choice of hitting ENTER to execute a Special or PL command, entering a blank line to store back to the edit buffer, or end a SQL statement with semi-colon and ENTER to execute it.

                You can, optionally, put a string after the :a, in which case things will be exactly as just described except the additional text will also be appended to the new immediate command. If you put a string after the :a which ends with ;, then the resultant new immediate command will just be executed right away, as if you typed in and entered the entire thing.

                If your edit buffer contains SELECT x FROM mytab and you run a:le, the resultant command will be SELECT x FROM mytable. If your edit buffer contains SELECT x FROM mytab and you run a: ORDER BY y, the resultant command will be SELECT x FROM mytab ORDER BY y. Notice that in the latter case the append text begins with a space character.

                :s/from regex/to string/switches

                The Substitution Command is the primary method for SqlTool command editing-- it operates upon the current edit buffer by default. The "to string" and the "switches" are both optional (though the final "/" is not). To start with, I'll discuss the use and behavior if you don't supply any substitution mode switches.

                Don't use "/" if it occurs in either "from string" or "to string". You can use any character that you want in place of "/", but it must not occur in the from or to strings. Example 

                    :s@from string@to string@

                The to string is substituted for the first occurrence of the (case-specific) from string. The replacement will consider the entire SQL statement, even if it is a multi-line statement.

                In the example above, the from regex was a plain string, but it is interpreted as a regular expression so you can do all kinds of powerful substitutions. See the perlre man page, or the java.util.regex.Pattern API Spec for everything you need to know about extended regular expressions.

                Don't end a to string with ";" in attempt to make a command execute. There is a substitution mode switch to use for that purpose.

                You can use any combination of the substitution mode switches.

                • Use "i" to make the searches for from regex case insensitive.

                • Use "g" to substitute Globally, i.e., to subsitute all occurrences of the from regex instead of only the first occurrence found.

                • Use ";" to execute the command immediately after the substitution is performed.

                • Use "m" for ^ and $ to match each line-break in a multi-line edit buffer, instead of just at the very beginning and every end of the entire buffer.

                If you specify a command number (from the command history), you end up with a feature very reminiscent of vi, but even more powerful, since the Perl/Java regular expression are a superset of the vi regular expressions. As an example, 

                                    :24 s/pin/needle/g;
                would start with command number 24 from command history, substitute "needle" for all occurrences of "pin", then execute the result of that substitution (and this final statement will of course be copied to the edit buffer and to command history).

                :w /path/to/file.sql
                This appends the contents of the current buffer (by default) to the specified file. Since what is being written are Special, PL, or SQL commands, you are effectively creating an SQL script.

                I find the ":/regex/" and ":/regex/;" constructs particularly handy for every-day usage. 

                                    :/\\d/;
                re-executes the last \d command that you gave (The extra "\" is needed to escape the special meaning of "\" in regular expressions). It's great to be able to recall and execute the last "insert" command, for example, without needing to check the history or keep track of how many commands back it was. To re-execute the last insert command, just run ":/insert/;". If you want to be safe about it, do it in two steps to verify that you didn't accidentally recall some other command which happened to contain the string "insert", like 
                    :/insert/
    :;
                (Executing the last only if you are satisfied when SqlTool reports what command it restored). Often, of course, you will want to change the command before re-executing, and that's when you combine the :s and :a commands.

                We'll finish up with a couple fine points about Edit/Buffer commands. You generally can't use PL variables in Edit/Buffer commands, to eliminate possible ambiguities and complexities when modifying commands. The :w command is an exception to this rule, since it can be useful to use variables to determine the output file, and this command does not do any "editing".

                The :? help explains how you can change the default regular expression matching behavior (case sensitivity, etc.), but you can always use syntax like "(?i)" inside of your regular expression, as described in the Java API spec for class java.util.regex.Pattern, found here. History-command-matching with the /regex/ construct is purposefully liberal, matching any portion of the command, case sensitive, etc., but you can still use the method just described to modify this behavior. In this case, you could use "(?-i)" at the beginning of your regular expression to be case-sensitive.

                PL Commands

                Essential PL Command

                * VARNAME = value

                Set the value of a variable. If the variable doesn't exist yet, it will be created. The most common use for this is so that you can later use it in SQL statements, print statements, and PL conditionals, by using the *{VARNAME} or *{:VARNAME} construct. The only difference between *{VARNAME} and *{:VARNAME} is that the former produces an error if VARNAME is not set, whereas the latter will expand to a zero-length string if VARNAME is not set.

                If you set a variable to an SQL statement (without the terminating ";") you can then use it as a PL alias like /VARNAME, as shown in this example.

                Example 8.2. Defining and using a PL alias (PL variable)

                    * qry = SELECT COUNT(*) FROM mytable
    \p The stored query is '*{qry}'
    /qry;
    /qry WHERE mass > 200;

                If you put variable definitions into the SQL file auto.sql in your home directory, those aliases/variables will always be available for interactive use.

                PL variables can be expanded within all commands other than : edit/history commands.

                * load VARNAME /file/path.txt
                Sets VARNAME to the content of the specified ASCII file.
                * prepare VARNAME
                Indicate that next command should be a SQL INSERT or UPDATE command containing one question mark. The value of VARNAME will be substuted for the ? variable. This does work for CLOB columns.
                * VARNAME _
                When next SQL command is run, instead of displaying the rows, just store the very first column value to variable VARNAME. This works for CLOB columns too. It also works with Oracle XML type columns if you use column labels and the getclobval function.
                * VARNAME ~
                Exactly the same as 
                * VARNAME ~
                except that the fetched results will be displayed in addition to setting the variable.
                * dump VARNAME /file/path.txt
                Store the value of VARNAME to the specified ASCII file.

                ? Variable

                You don't set the ? variable. It is just like the Bourne shell variable ? in that it is always automatically set to the first value of a result set (or the return value of other SQL commands). It works just like the 

                * VARNAME ~
                command described above, but it all happens automatically. You can, of course, dereference ? like any PL variable, but it does not list with the 
                list
                and 
                listvalues
                commands. You can see the value whenever you want by running 
                    \p  *{?}

                Note that PL commands are used to upload and download column values to/from local ASCII files, but the corresponding actions for binary files use the special \b commands. This is because PL variables are used for ASCII values and you can store any number of column values in PL variables. This is not true for binary column values. The \b commands work with a single binary byte buffer.

                See the SqlTool Procedural Language section below for information on using variables in other ways, and information on the other PL commands and features.

                Storing and retrieving binary files

                You can upload binary files such as photographs, audio files, or serialized Java objects into database columns. SqlTool keeps one binary buffer which you can load from files with the \bl command, or from a database query by doing a one-row query for any non-displayable type (including BLOB, OBJECT, and OTHER). In the latter case, the data returned for the first non-displayable column of the first result row will be stored into the binary buffer.

                Once you have data in the binary buffer, you can upload it to a database column (including BLOB, OBJECT, and OTHER type columns), or save it to a file. The former is accomplished by the special command \bp followed by a prepared SQL query containing one question mark place-holder to indicate where the data gets inserted. The latter is accomplished with the \bd command.

                You can also store the output from normal, displayable column into the binary buffer by using the special command \b. The very first column value from the first result row of the next SQL command will be stored to the binary byte buffer.

                Example 8.3. Inserting binary data into database from a file

                    \bl /tmp/favoritesong.mp3
    \bp
    INSERT INTO musictbl (id, stream) VALUES(3112, ?);

                Example 8.4. Downloading binary data from database to a file

                    SELECT stream FROM musictbl WHERE id = 3112;
    \bd /tmp/favoritesong.mp3

                You can also store and retrieve text column values to/from ASCII files, as documented in the Essential PL Command section.

                Command History

                The SQL history shown by the \h command, and used by other commands, is truncated to 100 entries, since its utility comes from being able to quickly view the history list. You can change the history length by setting the system property sqltool.historyLength to an integer like 

                java -Dsqltool.historyLength=100 -jar $HSQLDB_HOME/lib/hsqldb.jar urlid
                If there is any demand, I'll make the setting of this value more convenient.

                The SQL history list contains all executed commands other than Edit Buffer commands and comments, even if the command has a syntax error or fails upon execution. The reason for including bad commands is so that you can recall and fix them if you wish to. The same applies to the edit buffer. If you copy a command to the edit buffer by entering blank line, or if you edit the edit buffer, that edit buffer value will never make it into the command history until and if you execute it.

                Shell scripting and command-line piping

                You normally use non-interactive mode for input piping. You specify "-" as the SQL file name. See the Piping and shell scripting subsection of the Non-Interactive chapter.

                Emulating Non-Interactive mode

                You can run SqlTool interactively, but have SqlTool behave exactly as if it were processing an SQL file (i.e., no command-line prompts, error-handling that defaults to fail-upon-error, etc.). Just specify "-" as the SQL file name in the command line. This is a good way to test what SqlTool will do when it encounters any specific command in an SQL file. See the Piping and shell scripting subsection of the Non-Interactive chapter for an example.

                Non-Interactive

                Read the Interactive Usage section if you have not already, because much of what is in this section builds upon that. You can skip all discussion about Command History and the edit buffer if you will not use those interactive features.

                Important

                If you're doing data updates, remember to issue a commit command or use the --autoCommit switch.

                As you'll see, SqlTool has many features that are very convenient for scripting. But what really makes it superior for automation tasks (as compared to SQL tools from other vendors) is the ability to reliably detect errors and to control JDBC transactions. SqlTool is designed so that you can reliably determine if errors occurred within SQL scripts themselves, and from the invoking environment (for example, from a perl, Bash, or Python script, or a simple cron tab invocation).

                Giving SQL on the Command Line

                If you just have a couple Commands to run, you can run them directly from the comand-line or from a shell script without an SQL file, like this. 

                    java -jar $HSQLDB_HOME/lib/hsqldb.jar --sql 'SQL statement;' urlid

                Note

                The --sql automatically implies --noinput, so if you want to execute the specified SQL before and in addition to an interactive session (or stdin piping), then you must also give the --stdinput switch.

                Since SqlTool transmits SQL statements to the database engine only when a line is terminated with ";", if you want feedback from multiple SQL statements in an --sql expression, you will need to use functionality of your OS shell to include linebreaks after the semicolons in the expression. With any Bourne-compatible shell, you can include linebreaks in the SQL statements like this. 

                    java -jar $HSQLDB_HOME/lib/hsqldb.jar --sql '
        SQL statement number one;
        SQL statement
            number two;
        SQL statement three;
    ' urlid
                If you don't need feedback, just separate the SQL commands with semicolons and the entire expression will be chunked.

                The --sql switch is very useful for setting shell variables to the output of SQL Statements, like this. 

                    # A shell script
    USERCOUNT=`java -jar $HSQLDB_HOME/lib/hsqldb.jar --sql '
        select count(*) from usertbl;
    ' urlid` || {
        # Handle the SqlTool error
    }
    echo "There are $USERCOUNT users registered in the database."
    [ "$USECOUNT" -gt 3 ] && {   # If there are more than 3 users registered
        # Some conditional shell scripting

                SQL Files

                Just give paths to sql text file(s) on the command line after the urlid.

                Often, you will want to redirect output to a file, like 

                java -jar $HSQLDB_HOME/lib/hsqldb.jar sql... > /tmp/log.sql 2>&1

                (Skip the "2>&1" if you're on Windows).

                You can also execute SQL files from an interactive session with the "\i"' Special Command, but be aware that the default behavior in an interactive session is to continue upon errors. If the SQL file was written without any concern for error handling, then the file will continue to execute after errors occur. You could run \c false before \i filename, but then your SqlTool session will exit if an error is encountered in the SQL file. If you have an SQL file without error handling, and you want to abort that file when an error occurs, but not exit SqlTool, the easiest way to accomplish this is usually to add \c false to the top of the script.

                If you specify multiple SQL files on the command-line, the default behavior is to exit SqlTool immediately if any of the SQL files encounters an error.

                SQL files themselves have ultimate control over error handling. Regardless of what command-line options are set, or what commands you give interactively, if a SQL file gives error handling statements, they will take precedence.

                You can also use \i in SQL files. This results in nested SQL files.

                You can use the following SQL file, sample.sql, which resides in the sample directory of your HSQLDB distribution [1]. It contains SQL as well as Special Commands making good use of most of the Special Commands documented below. 

                /*
    $Id: sample.sql,v 1.5 2005/05/02 15:07:27 unsaved Exp $
    Examplifies use of SqlTool.
    PCTASK Table creation
*/

/* Ignore error for these two statements */
\c true
DROP TABLE pctasklist;
DROP TABLE pctask;
\c false

\p Creating table pctask
CREATE TABLE pctask (
    id integer identity,
    name varchar(40),
    description varchar,
    url varchar,
    UNIQUE (name)
);

\p Creating table pctasklist
CREATE TABLE pctasklist (
    id integer identity,
    host varchar(20) not null,
    tasksequence int not null,
    pctask integer,
    assigndate timestamp default current_timestamp,
    completedate timestamp,
    show bit default true,
    FOREIGN KEY (pctask) REFERENCES pctask,
    UNIQUE (host, tasksequence)
);

\p Granting privileges
GRANT select ON pctask TO public;
GRANT all ON pctask TO tomcat;
GRANT select ON pctasklist TO public;
GRANT all ON pctasklist TO tomcat;

\p Inserting test records
INSERT INTO pctask (name, description, url) VALUES (
    'task one', 'Description for task 1', 'http://cnn.com');
INSERT INTO pctasklist (host, tasksequence, pctask) VALUES (
    'admc-masq', 101, SELECT id FROM pctask WHERE name = 'task one');

commit;

                You can execute this SQL file with a Memory Only database with a command like 

                    java -jar $HSQLDB_HOME/lib/hsqldb.jar  --sql '
        create user tomcat password "x";
    ' mem path/to/hsqldb/sample/sample.sql

                (The --sql "create...;" arguments create an account which the script uses). You should see error messages betwen the Continue-on-error...true and Continue-on-error...false. The script purposefully runs commands that might fail there. The reason the script does this is to perform database-independent conditional table removals. (The SQL clause IF EXISTS is more graceful and succinct, and should be used if you don't need to support databases which don't support IF EXISTS). If an error occurs when continue-on-error is false, the script would abort immedately.

                Piping and shell scripting

                You can of course, redirect output from SqlTool to a file or another program. 

                    java -jar $HSQLDB_HOME/lib/hsqldb.jar urlid file.sql > file.txt 2>&1

    java -jar $HSQLDB_HOME/lib/hsqldb.jar urlid file.sql 2>&1 | someprogram...

                You can type commands in to SqlTool while being in non-interactive mode by supplying "-" as the file name. This is a good way to test how SqlTool will behave when processing your SQL files. 

                        java -jar $HSQLDB_HOME/lib/hsqldb.jar urlid -

                This is how you have SqlTool read its input from another program:

                Example 8.5. Piping input into SqlTool

                        echo "Some SQL commands with '$VARIABLES';" |
        java -jar $HSQLDB_HOME/lib/hsqldb.jar urlid -

                Make sure that you also read the Giving SQL on the Command Line section. The --sql switch is a great facility to use with shell scripts.

                Optimally Compatible SQL Files

                If you want your SQL scripts optimally compatible among other SQL tools, then don't use any Special or PL Commands. SqlTool has default behavior which I think is far superior to the other SQL tools, but you will have to disable these defaults in order to have optimally compatible behavior.

                These switches provide compatibilty at the cost of poor control and error detection.

                • --continueOnErr

                  The output will still contain error messages about everything that SqlTool doesn't like (malformatted commands, SQL command failures, empty SQL commands), but SqlTool will continue to run. Errors will not cause rollbacks (but that won't matter because of the following setting).

                • --autoCommit

                You don't have to worry about accidental expansion of PL variables, since SqlTool will never expand PL variables if you don't set any variables on the command line, or give any "* " PL commands. (And you could not have "* " commands in a compatible SQL file).

                Comments

                SQL comments of the form /*...*/ must begin where a (SQL/Special/Edit-Buffer/PL) Command could begin, and they end with the very first "*/" (regardless of quotes, nesting, etc. You may have as many blank lines as you want inside of a comment.

                Example 8.6. Valid comment example

                    SELECT count(*) FROM atable;
    /* Lots of
     comments interspersed among
     several lines */   SELECT count(*)
    FROM btable;

                Notice that a command can start immediate after the comment ends.

                Example 8.7. Invalid comment example

                    SELECT count(*) FROM
    /* atable */
    btable;

                This comment is invalid because you could not start another command at the comment location (because it is within an SQL Statement).

                You can try using /*...*/ in other locations, and -- style SQL comments, but SqlTool will not treat them as comments. If they occur within an SQL Statment, SqlTool will pass them to the database engine, and the DB engine will determine whether to parse them as comments.

                Special Commands and Edit Buffer Commands in SQL Files

                Don't use Edit Buffer / History Commands in your sql files, because they won't work. Edit Buffer / History Commands are for interactive use only. (But, see the Raw Mode section for an exception). You can, of course, use any SqlTool command at all interactively. I just wanted to group together the commands most useful to script-writers.

                \q [abort message]

                Be aware that the \q command will cause SqlTool to completely exit. If a script x.sql has a \q command in it, then it doesn't matter if the script is executed like 

                    java -jar .../hsqldb.jar urlid a.sql x.sql z.sql
                or if you use \i to read it in interactively, or if another SQL file uses \i to nest it. If \q is encountered, SqlTool will quit. See the SqlTool Procedural Language section for commands to abort an SQL file (or even parts of an SQL file) without causing SqlTool to exit.

                \q takes an optional argument, which is an abort message. If you give an abort message, the message is displayed to the user and SqlTool will exit with a failure status. If you give no abort message, then SqlTool will exit quietly with successful status. As a result, 

                \q
                means to make an immediate but graceful exit, whereas 
                \q Message
                means to abort immediately.

                \p [text to print]
                Print the given string to stdout. Just give "\p" alone to print a blank line.
                \i /path/to/file.sql
                Include another SQL file at this location. You can use this to nest SQL files. For database installation scripts I often have a master SQL file which includes all of the other SQL files in the correct sequence. Be aware that the current continue-upon-error behavior will apply to included files until such point as the SQL file runs its own error handling commands.
                \o [file/path.txt]

                Tee output to the specified file (or stop doing so). See the Generating Text or HTML Reports section.

                \=
                A database-independent way to commit your SQL session.
                \a [true|false]
                This turns on and off SQL transaction autocommits. Auto-commit defaults to false, but you can change that behavior by using the --autoCommit command-line switch.
                \c [true|false]

                A "true" setting tells SqlTool to Continue when errors are encountered. The current transaction will not be rolled back upon SQL errors, so if \c is true, then run the ROLLCACK; command yourself if that's what you want to happen. The default for interactive use is to continue upon error, but the default for non-interactive use is to abort upon error. You can override this behavior by using the --continueOnErr or the --abortOnErr command-line switch.

                With database setup scripts, I usually find it convenient to set "true" before dropping tables (so that things will continue if the tables aren't there), then set it back to false so that real errors are caught. DROP TABLE tablename IF EXISTS; is a more elegant, but less portable, way to accomplish the same thing.

                Tip

                It depends on what you want your SQL files to do, of course, but I usually want my SQL files to abort when an error is encountered, without necessarily killing the SqlTool session. If this is the behavior that you want, then put an explicit \c false at the top of your SQL file and turn on continue-upon-error only for sections where you really want to permit errors, or where you are using PL commands to handle errors manually. This will give the desired behavior whether your script is called by somebody interactively, from the SqlTool command-line, or included in another SQL file (i.e. nested).

                Important

                The default settings are usually best for people who don't want to put in any explicit \c or error handling code at all. If you run SQL files from the SqlTool command line, then any errors will cause SqlTool to roll back and abort immediately. If you run SqlTool interactively and invoke SQL files with \i commands, the scripts will continue to run upon errors (and will not roll back). This behavior was chosen because there are lots of SQL files out there that produce errors which can be ignored; but we don't want to ignore errors that a user won't see. I reiterate that any and all of this behavior can (and often should) be changed by Special Commands run in your interactive shell or in the SQL files. Only you know whether errors in your SQL files can safely be ignored.

                Automation

                SqlTool is ideal for mission-critical automation because, unlike other SQL tools, SqlTool returns a dependable exit status and gives you control over error handling and SQL transactions. Autocommit is off by default, so you can build a completely dependable solution by intelligently using \c commands (Continue upon Errors) and commit statements, and by verifying exit statuses.

                Using the SqlTool Procedural Language, you have ultimate control over program flow, and you can use variables for database input and output as well as for many other purposes. See the SqlTool Procedural Language section.

                Getting Interactive Functionality with SQL Files

                Some script developers may run into cases where they want to run with sql files but they alwo want SqlTool's interactive behavior. For example, they may want to do command recall in the sql file, or they may want to log SqlTool's command-line prompts (which are not printed in non-interactive mode). In this case, do not give the sql file(s) as an argument to SqlTool, but pipe them in instead, like 

                java -jar $HSQLDB_HOME/lib/hsqldb.jar urlid < filepath1.sql > /tmp/log.html 2>&1
                or 
                cat filepath1.sql... |
java -jar $HSQLDB_HOME/lib/hsqldb.jar urlid > /tmp/log.html 2>&1

                Character Encoding

                SqlTool defaults to the US-ASCII character set (for reading). You can use another character set by setting the system property sqlfile.charset, like 

                java -Dsqlfile.charset=UTF-8 -jar $HSQLDB_HOME/lib/hsqldb.jar urlid file.sql...

                You can also set this per urlid in the SqlTool configuration file. See the RC File Authentication Setup section about that.

                Generating Text or HTML Reports

                This section is about making a file containing the output of database queries. You can generate reports by using operating system facilities such as redirection, tee, and cutting and pasting. But it is much easier to use the "\o" and "\H" special commands.

                Procedure 8.4. Writing query output to an external file

                1. By default, everthing will be done in plain text. If you want your report to be in HTML format, then give the special command \H. If you do so, you will probably want to use filenames with an suffix of ".html" or ".htm" instead of ".txt" in the next step.

                2. Run the command \o path/to/reportfile.txt. From this point on, output from your queries will be appended to the specified file. (I.e. another copy of the output is generated.) This way you can continue to monitor or use output as usual as the report is generated.

                3. When you want SqlTool to stop writing to the file, run \o (or just quit SqlTool if you have no other work to do).

                4. If you turned on HTML mode with \H before, you can run \H again to turn it back off, if you wish.

                It is not just the output of "SELECT" statements that will make it into the report file, but

                Kinds of output that get teed to \o files

                • Output of SELECT statements.
                • Output of all "\d" Special Commands. (I.e., "\dt", "\dv", etc., and "\d OBJECTNAME").
                • Output of "\p" Special Commands. You will want to use this to add titles, and perhaps spacing, for the output of individual queries.
                Other output will go to your screen or stdout, but will not make it into the report file. Be aware that no error messages will go into the report file. If SqlTool is run non-interactively (including if you give any SQL file(s) on the command line), SqlTool will abort with an error status if errors are encountered. The right way to handle errors is to check the SqlTool exit status. (The described error-handling behavior can be modified with SqlTool command-line switches and Special Commands).

                Warning

                Remember that \o appends to the named file. If you want a new file, then use a new file name or remove the pre-existing target file ahead of time.

                Tip

                So that I don't end up with a bunch of junk in my report file, I usually leave \o off while I perfect my SQL. With \o off, I perfect the SQL query until it produces on my screen exactly what I want saved to file. At this point I turn on \o and run ":;" to repeat the last SQL command. If I have several complex queries to run, I turn \o off and repeat until I'm finished. (Every time you turn \o on, it will append to the file, just like we need).

                Usually it doesn't come to mind that I need a wider screen until a query produces lines that are too long. In this case, stretch your window and repeat the last command with the ":;" Edit Buffer Command.

                SqlTool Procedural Language

                Aka PL

                Most importantly, run SqlTool interactively and give the "*?" command to see what PL commands are available to you. I've tried to design the language features to be intuitive. Readers experience with significant shell scripting in any language can probably learn everything they need to know by looking at (and running!) the sample script sample/pl.sql in your HSQLDB distribution [1] and using the *? command from within an interactive SqlTool session as a reference. (By significant shell scripting, I mean to the extent of using variables, for loops, etc.).

                PL variables will only be expanded after you run a PL command (or set variable(s) from the command-line). We only want to turn on variable expansion if the user wants variable expansion. People who don't use PL don't have to worry about strings getting accidentally expanded.

                All other PL commands imply the "*" command, so you only need to use the "*" statement if your script uses PL variables and it is possible that no variables may be set before-hand (and no PL commands have been run previously). In this case, without "*", your script would silently use a literal value like "*{x}" instead of trying to expand it. With a preceding "*" command, PL will notice that the variable x has not been set and will generate an error. (If x had been set here will be no issue because setting a variable automatically turns on PL variable expansion).

                PL is also used to upload and download column values to/from local ASCII files, analogously to the special \b commands for binary files. This is explained above in the Interactive Essential PL Command section above.

                Variables

                • Use the * list command to list some or all variables; or * listvalues to also see the values.
                • You can set variables using the * VARNAME = value command. This document explains elsewhere how you can set a values to the contents of files, and to the return value of SQL statements and fetches.
                • You can also set variables using the --setvar command-line switch. I give a very brief but useful example of this below.
                • Variables are always expanded in SQL, Special, and PL commands if they are written like *{VARNAME} (assuming that a PL command has been run previously). Your SQL scripts can give good feedback by echoing the value of variables with the "\p" special command. Use the construct *{:VARNAME} to expand the variable, but to expand to a zero-length string instead of fail if VARNAME is not set.

                • A variable written like /VARNAME is expanded if it begins an SQL Statement. This usage is called PL Aliasing. See the PL Aliases section below.

                • Variables are normally written like *VARNAME in logical expressions to prevent them from being evaluated too early. See below about logical expressions.

                • You can't do math with expression variables, but you can get functionality like the traditional for (i = 0; i < x; i++) by appending to a variable and testing the string length, like 

                      * while (*i < ${x})
        * i = *{i}.
                  i will be a growing line of dots.

                • Variable names must not contain white space, or the characters "}" or "=".

                PL Aliases

                PL Aliasing just means the use of a PL variable as the first thing in an SQL statement, with the shortcut notation /VARNAME.

                /VARNAME must be followed by whitespace or terminate the Statement, in order for SqlFile to tell where the variable name ends.

                Note

                Note that PL aliases are a very different thing from SQL aliases or HSQLDB aliases, which are features of databases, not SqlFile.

                If the value of a variable is an entire SQL command, you generally do not want to include the terminating ";" in the value. There is an example of this above.

                PL aliasing may only be used for SQL statements. You can define variables for everything in a Special or PL Command, except for the very first character ("\" or "*"). Therefore, you can use variables other than alias variables in Special and PL Commands. Here is a hyperbolically impractical example to show the extent to which PL variables can be used in Special commands even though you can not use them as PL aliases. 

                        sql> * qq = p Hello Butch
        sql> \*{qq} done now
        Hello Butch done now
                (Note that the \* here is not the special command "\*", but is the special command "\p" because "*{qq}" resolves to "p").

                Here is a short SQL file that gives the specified user write permissions on some application tables.

                Example 8.8. Simple SQL file using PL

                    /*
       grantwrite.sql

       Run SqlTool like this:
           java -jar path/to/hsqldb.jar -setvar USER=debbie grantwrite.sql
     */

    /* Explicitly turn on PL variable expansion, in case no variables have
       been set yet.  (Only the case if user did not set USER).
    */
    *

    GRANT all ON book TO *{USER};
    GRANT all ON category TO *{USER};

                Note that this script will work for any (existing) user just by supplying a different user name on the command-line. I.e., no need to modify the tested and proven script. There is no need for a commit statement in this SQL file since no DML is done. If the script is accidentally run without setting the USER variable, SqlTool will give a very clear notificaton of that.

                The purpose of the plain "*" command is just so that the *{USER} variables will be expanded. (This would not be necessary if the USER variable, or any other variable, were set, but we don't want to depend upon that).

                Logical Expressions

                Logical expressions occur only inside of logical expression parentheses in PL statements. For example, if (*var1 > astring) and while (*checkvar). (The parentheses after "foreach" do not enclose a logical expression, they just enclose a list).

                There is a critical difference between *{VARNAME} and *VARNAME inside logical expressions. *{VARNAME} is expanded one time when the parser first encounters the logical expression. *VARNAME is re-expanded every time that the expression is evaluated. So, you would never want to code * while (*{X} < 5) because the statement will always be true or always be false. (I.e. the following block will loop infinitely or will never run).

                Don't use quotes or whitespace of any kind in *{VARNAME} variables in expressions. (They would expand and then the expression would most likely no longer be a valid expression as listed in the table below). Quotes and whitespace are fine in *VARNAME variables, but it is the entire value that will be used in evaluations, regardless of whether quotes match up, etc. I.e. quotes and whitespace are not special to the token evaluator.

                Logical Operators

                TOKEN
                The token may be a literal, a *{VARNAME} which is expanded early, or a *VARNAME which is expanded late. (You usually do not want to use *{VARNAME} in logical expressions). False if the token is not set, empty, or "0". True otherwise.
                TOKEN1 == TOKEN2
                True if the two tokens are equivalent "strings".
                TOKEN1 <> TOKEN2
                Ditto.
                TOKEN1 >< TOKEN2
                Ditto.
                TOKEN1 > TOKEN2
                True if the TOKEN1 string is longer than TOKEN2 or is the same length but is greater according to a string sort.
                TOKEN1 < TOKEN2
                Similarly to TOKEN1 > TOKEN2.
                ! LOGICAL_EXPRESSION
                Logical negation of any of the expressions listed above.

                *VARNAMEs in logical expressions, where the VARNAME variable is not set, evaluate to an empty string. Therefore (*UNSETVAR = 0) would be false, even though (*UNSETVAR) by itself is false and (0) by itself is false. Another way of saying this is that *VARNAME in a logical expression is equivalent to *{:VARNAME} out of a logical expression.

                When developing scripts, you definitely use SqlTool interactively to verify that SqlTool evaluates logical expressions as you expect. Just run * if commands that print something (i.e. \p) if the test expression is true.

                Flow Control

                Flow control works by conditionally executing blocks of Commands according to conditions specified by logical expressions.

                The conditionally executed blocks are called PL Blocks. These PL Blocks always occur between a PL flow control statement (like * foreach, *while, * if) and a corresponding * end PL Command (like * end foreach).

                Caution

                Be aware that the PL block reader is ignorant about SQL statements and comments when looking for the end of the block. It just looks for lines beginning with some specific PL commands. Therefore, if you put a comment line before a PL statement, or if a line of a multi-line SQL statement has a line beginning with a PL command, things may break.

                I am not saying that you shouldn't use PL commands or SQL commands inside of PL blocks-- you definitely should! I'm saying that in PL blocks you should not have lines inside of SQL statments or comments which could be mistaken for PL commands. (Especially, "commenting out" PL end statements will not work if you leave * end at the beginning of the line).

                (This limitation will very likely be removed in a future version of SqlTool).

                The values of control variables for foreach and while PL blocks will change as expected.

                There are * break and * continue, which work as any shell scripter would expect them to. The * break command can also be used to quit the current SQL file without triggering any error processing. (I.e. processing will continue with the next line in the including SQL file or interactive session, or with the next SQL file if you supplied multiple on the command-line).

                Below is an example SQL File that shows how to use most PL features. If you have a question about how to use a particular PL feature, check this example before asking for help. This file resides in the sample directory with the name pl.sql [1]. Definitely give it a run, like 

                java -jar $HSQLDB_HOME/lib/hsqldb.jar mem $HSQLDB_HOME/pl.jar

                Chunking

                We hereby call the ability to transmit multiple SQL commands to the database in one transmission chunking. Unless you are in Raw mode, SqlTool only transmits commands to the database engine when it reads in a ";" at the end of a line of an SQL command. Therefore, you normally want to end each and every SQL command with ";" at the end of a line. This is because the database can only send one status reply to each JDBC transmission. So, while you could run 

                    SELECT * FROM t1; SELECT * FROM t2;
                SqlTool can only display the results from the last query. This is a limitation of the client/server nature of JDBC, and applies to any JDBC client. There are, however, situations where you don't need immediate feedback from every SQL command. For example,

                Example 8.10. Single-line chunking example

                    INSERT INTO t1 VALUES(0); SELECT * FROM t1;
                It's useful because the output of the second SQL command will tell you whether the first SQL command succeeded. So, you won't miss the status output from the first command.

                Why?

                The first general reason to chunk SQL commands is performance. For standalone databases, the most common performance bottleneck is network latency. Chunking SQL commands can dramatically reduce network traffic.

                The second general reason to chunk SQL commands is if your database requires you to send multiple commands in one transmission. This is often the case when you need to tell the database the SQL or PL/SQL commands that comprise a stored procedure, function, trigger, etc.

                How?

                The most simple way is enter as many SQL commands as you want, but just do not end a line with ";" until you want the chunk to transmit.

                Example 8.11. Multi-line chunking example

                    INSERT INTO t1 VALUES (1)
    ; INSERT INTO t1 VALUES (2)
    ; SELECT * FROM t1;
                If you list your command history with \s, you will see that all 3 SQL commands in 3 lines are in one SqlTool command. You can recall this SqlTool command from history to re-execute all three SQL commands.

                The other method is by using Raw Mode. Go to the Raw Mode section to see how. You can enter any text at all, exactly how you want it to be sent to the database engine. Therefore, in addition to chunking SQL commands, you can give commands for non-SQL extensions to the database. For example, you could enter JavaScript code to be used in a stored procedure.

                Raw Mode

                You begin raw mode by issuing the Special Command "\.". You can then enter as much text in any format you want. When you are finished, enter a line consisting of only ".;" to store the input to the edit buffer and send it to the database server for execution.

                This paragraph applies only to interactive usage. Interactive users may may end the raw input with ":." instead of ".;". This will just save the input to the edit buffer so that you can edit it and send it to the database manually. You can look at the edit buffer with the ":b" Buffer Command. You would normally use the command ":;" to send the buffer to the database after you are satisfied with it. You'll notice that your prompt will be the continuation prompt between entering "\." and terminating the raw input with ".;" or ":.".

                Example 8.12. Interactive Raw Mode example

                    sql> \.
    Enter RAW SQL.  No \, :, * commands.
    End with a line containing only ".;" to send to database,
    or ":." to store to edit buffer for editing or saving.
    -----------------------------------------------------------
    raw> line one;
      +> line two;
      +> line three;
      +> :.
    Raw SQL chunk moved into buffer.  Run ":;" to execute the chunk.
    sql> :;
    Executing command from buffer:
    line one;
    line two;
    line three;

    SQL Error at 'stdin' line 13:
    "line one;
    line two;
    line three;"
    Unexpected token: LINE in statement [line]
    sql>
                The error message "Unexpected token: LINE in statement [line]" comes from the database engine, not SqlTool. All three lines were transmitted to the database engine.

                Edit Buffer Commands are not available when running SqlTool non-interactively.

                PL/SQL

                Note

                PL/SQL is not the same as PL. PL is the procedural language of SqlFile and is independent of your back-end database. PL commands always begin with *. PL/SQL is processed on the server side and you can only use it of your database supports it. You can not intermix PL and PL/SQL (except for setting a PL variable to the output of PL/SQL execution), because when you enter PL/SQL to SqlTool that input is not processed by SqlFile.

                Use Raw Mode to send PL/SQL code blocks to the database engine. You do not need to enter the "\." command to enter raw mode. Just begin a new SqlTool command line with "DECLARE" or "BEGIN", and SqlTool will automatically put you into raw mode. See the Raw Mode section for details.

                The following sample SQL file resides at sample/plsql.sql in your HSQLDB distribution [1]. This script will only work if your database engine supports standard PL/SQL, if you have permission to create the table "T1" in the default schema, and if that object does not already exist.

                Example 8.13. PL/SQL Example

                Using hsqltool.jar and hsqldbutil.jar

                This section is for those users who want to use SqlTool but without the overhead of hsqldb.jar (or who want to use a new SqlTool build with an older HSQLDB distribution).

                If you do not need to directly use JDBC URLs like jdbc:hsqldb:mem: + something, jdbc:hsqldb:file: + something, or jdbc:hsqldb:res: + something, then you can use hsqltool.jar in place of the much larger hsqldb.jar file. hsqltool.jar will work for all JDBC databases other than HSQLDB Memory-only and In-process databases (the latter are fine if you access them via a HSQLB Server or WebServer). You will have to supply the JDBC driver for non-HSQLDB URLs, of course.

                hsqltool.jar includes the HSQLDB JDBC driver. If you do not need to connect to HSQLDB databases at all, then hsqldbutil.jar is what you want. hsqldbutil.jar contains everything you need to run SqlTool and DatabaseManagerSwing against non-HSQLDB databases... well, besides the JDBC drivers for the target databases.

                The HSQLDB distribution doesn't "come with" pre-built hsqltool.jar and hsqldbutil.jar files. You need to "build" them, but that is very easy to do.

                These instructions assume that you are capable of running an Ant build. See the Building HSQLDB chapter if you need more details than what you see here.

                1. Download and extract a current HSQLDB distribution. If you don't want to use the source code, documentation, etc., you can use a temporary directory and remove it afterwards.

                2. Cd to the build directory under the root directory where you extracted the distribution to.

                3. Run ant hsqldbutil or ant hsqltool according to the criteria above. (If your goal is to use this jar with an older HSQLDB distribution, then you definitely need to build hsqlbutil.jar).

                4. If you're going to clean up afterwards, copy the jar that you built out of lib to a safe location first.

                If you are using the HSQLDB JDBC driver (i.e., you're connecting up to a URL like jdbc:hsqldb:hsql + something or jdbc:hsqldb:http + something), you invoke SqlTool exactly as with hsqldb.jar except you use the file path to your new jar file instead of the path to hsqldb.jar.

                If you are using a non-HSQLDB JDBC driver, you must set your CLASSPATH to include this new jar file and your JDBC driver, then run SqlTool like 

                        java org.hsqldb.util.SqlTool ...
                You can specify your JDBC driver class either with the --driver switch to SqlTool, or in your RC file stanza (the last method is usually more convenient).

                Delimiter-Separated-Value Imports and Exports

                Note

                This feature is independent of HSQLDB Text Tables, a server-side feature of HSQLDB. It makes no difference to SqlTool whether the source or target table of your export/import is a memory, cache, or text table. Indeed, like all features of SqlTool, it works fine with other JDBC databases. It works great, for example to migrate data from a table of one type to a table of another type, or to another schema, or to another database instance, or to another database system.

                This feature is what most business people call "CSV", but these files are more accurately called Delimiter Separated Value files because the delimiter is usually not a comma, and, more importantly, we purposefully choose an effective delimiter instead of the CSV method of using a delimiter which works in some cases and then use quotes and back-slashes to escape occurrence of the delimiter in the actual data. Just by choosing a delimiter which never needs escaping, we eliminate the whole mess, and the data in our files always looks just like the corresponding data in the database. To make this CSV / Delimiter-separated-value dintinction clear, I use the suffix ".dsv" for my data files. This leads me to stipulate the abbreviation DSV for the Delimiter Separated Value feature of HSQLDB.

                Use the \x command to eXport a table to a DSV file, and the \m command to iMport a DSV file into a pre-existing table.

                The row and column delimiters may be any String, not just a single character. And just as the delimiter capability is more general than traditional CSV delimiters, the export function is also more general than just a table data exporter. Besides the trivial generalization that you may specify a view or other virtual table name in place of a table name, you can alternatively export the output of any query which produces normal text output. A benefit to this approach is that it allows you to export only some columns of a table, and to specify a WHERE clause to narrow down the rows to be exported (or perform any other SQL transformation, mapping, join, etc.). One specific use for this would be to exclude columns of binary data (which can be exported by other means, such as a PL loop to store binary values to files with the \bd command).

                Note that the import command will not create a new table. This is because of the impossibility of guessing appropriate types and constraints based only on column names and a data sampling (which is all that a DSV-importer has access to). Therefore, if you wish to populate a new table, create the table before running the import. The import file does not need to have data for all columns of a table. The only required columns are those required by database constraints (non-null, indexes, keys, etc.) One specific reason to omit columns is if you want values of some columns to be created automatically by column DEFAULT settings, triggers, HSQLDB identity sequences, etc. Another reason would be to skip binary columns.

                Simple DSV exports and imports using default settings

                Even if you need to change delimiters, table names, or file names from the defaults, I suggest that you run one export and import with default settings as a practice run. A memory-only HSQLDB instance is ideal for test runs like this.

                This command exports the table icf.projects to the file projects.dsv in the current directory (where you invoked SqlTool from). By default, the output file name will be the specified source table name plus the extension .dsv.

                Example 8.14. DSV Export Example

                    SET SCHEMA icf;
    \x projects
                We could also have run \x icf.projects (which would have created a file named icf.projects.dsv) instead of changing the session schema. In this example we have chosen to make the export file name independent of the schema to facilitate importing it into a different schema.

                Take a look at the output file. Notice that the first line consists of column names, not data. This line is present because it will be needed if the file is to used for a DSV import. Notice the following characterstics about the export data. The column delimiter is the pipe character "|". The record delimiter is the default line delimiter character(s) for your operating system. The string used to represent database NULLs is [null]. See the next section for how to change these from their default values.

                This command imports the data from the file projects.dsv in the current directory (where you invoked SqlTool from) into the table newschema.projects. By default, the output table name will be the input filename after removing optional leading directory and trailing final extension.

                Example 8.15. DSV Import Example

                    SET SCHEMA newschema;
    \m projects.dsv
                If the DSV file was named with the target schema, you would have skipped the SET SCHEMA command, like \m newschema.projects.dsv.

                Specifying queries and options

                For a hands on example of a DSM import which generates an import report and uses some other options, change to directory HSQLDB/sample and play with the working script dsv-sample.sql [1]. You can execute it like 

                    java -jar ../lib/hsqldb.jar mem dsv-sample.sql
                (assuming that you are using the supplied sqltool.rc file or have have urlid mem set up.

                The header line in the DSV file is required at this time. (If there is user demand, it can be made optional for exporting, but it will remain required for importing).

                Your export will fail if the column or record delimiter, or the null representation value occurs in the data being exported. You change these values by setting the PL variables *DSV_COL_DELIM, *DSV_ROW_DELIM, *DSV_NULL_REP. Notice that the asterisk is part of the variable names, to indicate that these variables are used by SqlTool internally. When specifying delimiters, you can use the escape seqpences \n, \r, \f, \t, \\, and decimal, octal or hex specifications like \20, \020, \0x20. For example, to change the column delimiter to the tab character, you would give the command 

                    * *DSV_COL_DELIM = \t

                For imports, you must always specify the source DSV file path. If you want to export to a different file than one in the current directory named according to the source table, set the PL variable *DSV_TARGET_FILE, like 

                    * *DSV_TARGET_FILE = /tmp/dtbl.dsv

                For exports, you must always specify the source table name or query. If you want to import to a table other than that derived from the input DSV file name, set the PL variable *DSV_TARGET_TABLE. The table name may contain a schema name prefix.

                You don't need to import all of the columns in a data file. To designate the fields to be skipped, iether set the PL PL variable *DSV_SKIP_COLUMNS, or replace the column names in the header line to "-" (hyphen). The value of *DSV_SKIP_COLUMNS is case-insensitive, and multiple column names are separated with white space and/or commas.

                You can specify a query instead of a tablename with the \x command in order to filter or transform data from a table or view, or to export the output of a join, etc. You must set the PL variable *DSV_TARGET_FILE, as explained above (since there is no table name from which to automatically map a file name).

                Example 8.16. DSV Export of an Arbitrary SELECT Statement

                    * *DSV_TARGET_FILE = outfile.txt
    \x SELECT entrydate, 2 * aval "Double aval", modtime FROM bs.dtbl
                Note that I specified the column label alias "Double aval" so that the label for that column in the DSV file header will not be blank.

                By default, imports will abort as soon as a error is encountered during parsing the file or inserting data. If you invoke SqlTool with a SQL script on the command line, the failure will cause SqlTool to roll back and exit. If run interactively, you can decide whether to commit or roll back the rows that inserted before the failure. You can modify this behavior with the \a and \c settings.

                If you set either a reject dsv file or a reject report file, then failures during imports will be reported but will not cause the import to abort. When run in this way, SqlTool will give you a report at the end about how many records were skipped, rejected, and successfully inserted. The reject dsv file is just a dsv file with exact copies of the dsv records that failed to insert. The reject report file is a HTML report which lists, for every rejected record, why that record was rejected.

                To allow for user-friendly entry of headers, we require that tables for DSV import/exports use standard column names. I.e., no column names that require quoting. The DSV import and export parsers are very smart and user-friendly. The data types of columns are checked so that the parser can make safe assumptions about white space and blank entries in the data. If a column is a JDBC Boolean type, for example, then we know that a field value of " True " obviously means "True", and that a field value of "" obviously means null. Since we require vanilla style column names, we allow white space anywhere in the header column. We allow blank lines anywhere (where "lines" are delimited by *DSV_ROW_DELIM). By default, commented lines are ignored, and the comment character can be changed from its default value.

                Run the command "\x?" or "\m?" to see the several system PL variables which you can set to adjust reject file behavior, commenting behavior, and other DSV features.

                You can also define some settings right in the DSV file, and you can even specify multiple header lines in a single DSV file. I use this last feature to import data from one data set into multple tables that are joined. Since I don't have any more time to dedicate to explaining all of these features, I'll give you some examples from working DSV files and let you take it from there.

                Example 8.17. Sample DSV headerswitch settings

                    # RCS keyword was here.

    headerswitch{
    itemdef:name|-|-|hardness|breakdc|-
    simpleitemdef:itemdef_name|maxvalue|weight|-|-|maxhp
    }
                I'll just note that the prefixes for the header rows must be of format target-table-name + :. You can use * for target-table-name here, for the obvious purpose.

                Example 8.18. DSV targettable setting

                    targettable=t
                This last example is from the SqlTool unit test file dsv-trimming.dsv. These special commands must be at the top of the file (before any normal data or header lines).

                There is also the *DSV_CONST_COLS setting, which you can use to automatically write static, constant values to the specified columns of all inserted rows.

                Unit Testing SqlTool

                The SqlTool unit tests reside at testrun/sqltool in the HSQLDB source code repository. Just run the runtests.bash script from that directory to execute all of the tests. Read the file README.txt to find out all about it, including everything you'd need to know to test your own scripts or to add more unit test scripts for SqlTool.


                [1] To reduce the time I will need to spend maintaining this document, in this chapter I am giving the path to the sample directory as it is in HSQLDB 1.9.x distributions, namely, HSQLDB_HOME/sample. HSQLDB 1.8.x users should translate these sample directory paths to use HSQLDB_HOME/src/org/hsqldb/sample/....

                Purpose
                Building with Ant
                Obtaining Ant
                Building Hsqldb with Ant
                Building with DOS Batch Files
                Hsqldb CodeSwitcher
                Building documentation

                Purpose

                From 1.8.0, the supplied hsqldb.jar file is built with Java 1.5. If you want to run the engine under JDK1.3 or earlier, you should rebuild the jar with Ant.

                Building with Ant, from the Apache Jakarta Project

                Ant (Another Neat Tool) is used for building hsqldb. The version currently used to test the build script is 1.6.1 but versions since 1.5.1 should also be compatible.

                Obtaining Ant

                Ant is a part of the Jakarta/Apache Project.

                Building Hsqldb with Ant

                Once you have unpacked the zip package for hsqldb, under the /hsqldb folder, in /build there is a build.xml file that builds the hsqldb.jar with Ant (Ant must be already installed). To use it, change to /build then type:

                 ant -projecthelp

                This displays the available ant targets, which you can supply as command line arguments to ant. These include

                hsqldb

                to make the hsqldb.jar

                explainjars

                Lists all targets which build jar files, with an explanation of the purposes of the different jars.

                clean

                to clean up the /classes directory that is created

                cleanall

                to remove the old jar as well

                javadoc

                to build javadoc

                hsqldbmain

                to build a smaller jar for HSQLDB that does not contain utilities

                hsqljdbc

                to build an extremely small jar containing only the client-side JDBC driver (does not support direct connection to HSQLDB URLs of the form jdbc:hsldb:mem:*, jdbc:hsqldb:file:*, nor jdbc:hsqldb:res:*).

                hsqldbmin

                to build a small jar that supports HSQLDB URLs of the form jdbc:hsqldb:mem:*, jdbc:hsqld:file*, jdbc:hsqldb:res:*; but not network URLs like jdbc:hsql* or jdbc:http*.

                hsqldbtest

                to build a larger jar for hsqldb that contains tests

                ...

                Many more targets are available. Run ant -projecthelp and ant explainjars.

                HSQLDB can be built in any combination of three JRE (Java Runtime Environment) versions and many jar file sizes. The smallest jar size(hsqljdbc.jar) contains only the HSQLDB JDBC Driver client. The default size (hsqldb.jar) also contains server mode support and the utilities. The largest size (hsqldbtest.jar)includes some test classes as well. Before building the hsqldbtest.jar package, you should download the junit jar from http://www.junit.org and put it in the /lib directory, alongside servlet.jar, which is included in the .zip package.

                Just run ant explainjars for a concise list of all available jar files.

                If you want your code built for debugging, as opposed to high performance, make a file named build.properties in your build directory with the contents 

                build.debug: true
                The resulting Java binaries will be larger and slower, but exception stack traces will contain source code line numbers, which can be extremely useful for debugging.

                The preferred method of rebuilding the jar is with Ant. After installing Ant on your system use the following command from the /build directory:

                ant explainjars

                The command displays a list of different options for building different sizes of the HSQLDB Jar. The default is built using:

                Example A.1. Buiding the standard Hsqldb jar file with Ant

                ant hsqldb

                The Ant method always builds a jar with the JDK that is used by Ant and specified in its JAVA_HOME environment variable. Building with JDK 1.4.x or 1.5.x will result in a jar that is not backward compatible.

                From version 1.7.2, use of JDK 1.1.x is not recommended for building the JAR, even for running under JDK 1.1.x -- use JDK 1.3.1 for compatibility with 1.1.x. This is done in the following way. JDK 1.3.1 should be used as the JAVA_HOME for ant. You then issue the following commands. The first command will make the sources compatible with JDK 1.3, the second command modifies the sources further so that the compiled result can run under jdk 1.1 as well. The third command builds the jar.

                ant switchtojdk12
ant switchtojava1target
ant hsqldb

                Building with DOS Batch Files

                UNIX users must use Ant to build hsqldb.

                For DOS/Windows users, a set of MSDOS batch files is provided as an example. These files produce only the default jar size. The path and classpath variables for the JDK should of course be set before running any of the batch files. These files are not currently maintained and will probably need some additions and changes to work correctly. Please see the build.xml file for up-to-date file

                If you are compiling for JDK's other than 1.4.x, you should use the appropriate switchToJDK11.bat or switchToJDK12.bat to adapt the source files to the target JDK before running the appropriate buildJDK11.bat or buildJDK12.bat JDK and JRE versions.

                Hsqldb CodeSwitcher

                CodeSwitcher is a tool to manage different version of Java source code. It allows to compile HSQLDB for different JDKs. It is something like a precompiler in C but it works directly on the source code and does not create intermediate output or extra files.

                CodeSwitcher is used internally in HSQLDB build scripts. You do not have to use it separately to compile HSQLDB.

                CodeSwitcher reads the source code of a file, removes comments where appropriate and comments out the blocks that are not used for a particular version of the file. This operation is done for all files of a defined directory, and all subdirectories.

                Example A.2. Example source code before CodeSwitcher is run

                        ...

    //#ifdef JAVA2

        properties.store(out,"hsqldb database");

    //#else

    /*

        properties.save(out,"hsqldb database");

    */

    //#endif

        ...

                The next step is to run CodeSwitcher.

                Example A.3. CodeSwitcher command line invocation

                    java org.hsqldb.util.CodeSwitcher . -JAVA2

                The '.' means the program works on the current directory (all subdirectories are processed recursively). -JAVA2 means the code labelled with JAVA2 must be switched off.

                Example A.4. Source code after CodeSwitcher processing

                        ...

    //#ifdef JAVA2

    /*

        pProperties.store(out,"hsqldb database");

    */

    //#else

        pProperties.save(out,"hsqldb database");

    //#endif

        ...

                For detailed information on the command line options run java org.hsqldb.util.CodeSwitcher. Usage examples can be found in the switchtojdk1*.bat files in the /build directory.

                Building documentation

                To build the User Guide in HTML format, you must have the Docbook stylesheets installed locally. The Docbook stylesheets are available on the Internet. On Linux, just install the docbook-xsl-stylesheets rpm. Then add an entry to build.properties in your build directory with contents like 

                docbook.xsl.home: /usr/share/sgml/docbook/docbook-xsl-stylesheets
                Where you specify your local path to the base directory of your Docbook stylesheet installation. Build like

                Example A.5. Building HTML User Guides

                ant docbooks-html
ant docbooks-chunk

                To build the User Guide in PDF format, you must also have the Java FOP system installed locally. FOP is available for free download on the Internet. Add an entry to build.properties in your build directory with contents like 

                fop.home /usr/local/fop-0.20.5
                Where you specify your local path to the base directory of your FOP installation.

                Example A.6. Building User Guides in all formats

                ant docbook
                Don't pay too much attention to error messages by FOP, because they are really warnings, but do check the output. If there are problems with the PDF output, try using a newer version of FOP.

                Important

                By default, your docs will fail to build if you do not have Internet connectivity. This is because our primary Docbook source file references the Docbook DTDs via Internet URL. You can build without Internet connectivity by installing the Docbook DTDs and editing our primary Docbook source file. Docbook is available on the Internet. On Linux, just install the docbook-dtds or docbook rpm. Then make one edit to the file docsrc/guide/guide.xml in your HSQLDB distribution. Change the line containing 

                "http://www.oasis-open.org/docbook/xml/4.2CR1/docbookx.dtd" [
                to 
                "file:///usr/share/xml/docbook/schema/dtd/4.2/docbookx.dtd" [
                where the second filepath is the path to the docbookx.dtd file within your Docbook installation.

                Appendix C. Hsqldb Database Files and Recovery

                This text is based on HypersonicSQL documentation, updated to reflect the latest version 1.8.0 of HSQLDB.

                $Date: 2005/07/01 17:06:32 $

                States
                Procedures

                Startup
                Repair

                The Standalone and Client/Server modes will in most cases use files to store all data to disk in a persistent and safe way. This document describes the meaning of the files, the states and the procedures followed by the engine to recover the data.

                A database named 'test' is used in this description. The database files will be as follows.

                Database Files

                test.properties

                Contains the entry 'modified'. If the entry 'modified' is set to 'yes' then the database is either running or was not closed correctly (because the close algorithm sets 'modified' to 'no' at the end).

                test.script

                This file contains the SQL statements that makes up the database up to the last checkpoint - it is in synch with test.backup.

                test.data

                This file contains the (binary) data records for CACHED tables only.

                test.backup

                This is compressed file that contains the complete backup of the old test.data file at the time of last checkpoint.

                test.log

                This file contains the extra SQL statements that have modified the database since the last checkpoint (something like the 'Redo-log' or 'Transaction-log', but just text).

                In the above list, a checkpoint results from both a CHECKPOINT command and a SHUTDOWN command.

                States

                Database is closed correctly

                State after using the command SHUTDOWN

                • The test.data file is fully updated.

                • The test.backup contains the compressed test.data file.

                • The test.script contains the information in the database, excluding data for CACHED and TEXT tables.

                • The test.properties contains the entry 'modified' set to 'no'.

                • There is no test.log file.

                Database is closed correctly with SHUTDOWN SCRIPT

                State after using the command SHUTDOWN SCRIPT

                • The test.data file does not exist; all CACHED table data is in the test.script file

                • The test.backup does not exist.

                • The test.script contains the information in the database, including data for CACHED and TEXT tables.

                • The test.properties contains the entry 'modified' set to 'no'.

                • There is no test.log file.

                Database is aborted

                This may happen by sudden power off, Ctrl+C in Windows, but may be simulated using the command SHUTDOWN IMMEDIATELY.

                Aborted Database state

                • The test.properties still containes 'modified=yes'.

                • The test.script contains a snapshot of the database at the last checkpoint and is OK.

                • The test.data file may be corrupt because the cache in memory was not written out completely.

                • The test.backup file contains a snapshot of test.data that corresponds to test.script.

                • The test.log file contain all information to re-do all changes since the snanapshot. As a result of abnormal termination, this file may be partially corrupt.

                Procedures

                The database engine performs the following procedures internally in different circumstances.

                Clean Shutdown

                Procedure C.1. Clean Hsqldb database shutdown

                1. The test.data file is written completely (all the modified cached table rows are witten out) and closed.

                2. The test.backup.new is created (containing the compressed test.data file)

                3. The file test.script.new is created using the information in the database (and thus shrinks because no UPDATE and DELETE statements; only INSERT).

                4. The entry 'modified' in the properties file is set to 'yes-new-files'

                5. The file test.script is deleted

                6. The file test.script.new is renamed to test.script

                7. The file test.backup is deleted

                8. The file test.backup.new is renamed to test.backup

                9. The entry 'modified' in the properties file is set to 'no'

                10. The file test.log is deleted

                Startup

                Procedure C.2. Database is opened

                1. Check if the database files are in use (by checking a special test.lck file).

                2. See if the test.properties file exists, otherwise create it.

                3. If the test.properties did not exist, then this is a new database. Create the empty test.log to append new commands.

                4. If it is an existing database, check in the test.properties file if 'modified=yes'. This would mean last time it was not closed correctly, and thus the test.data file may be corrupted or incomplete. In this case the 'REPAIR' algorithm is executed (see below), before the database is opened normally.

                5. Otherwise, if in the test.properties file 'modified=yes-new-files', then the (old) test.backup and test.script files are deleted and the new test.script.new file is renamed to test.script.

                6. Open the test.script file and execute the commands.

                7. Create the empty test.log to append new commands.

                Repair

                The current test.data file is corrupt, but with the old test.data (from the test.backup file and test.script) and the current test.log, the database is made up-to-date. The database engine takes these steps:

                Procedure C.3. Database Repair

                1. Restore the old test.data file from the backup (uncompress the test.backup and overwrite test.data).

                2. Execute all commands in the test.script file.

                3. Execute all commands in the test.log file. If due to corruption, an exception is thrown, the rest of the lines of command in the test.log file are ignored.

                4. Close the database correctly (including a backup).

                Purpose

                Many questions repeatedly asked in Forums and mailing lists are answered in this guide. If you want to use HSQLDB with your application, you should read this guide. This document covers system related issues. For issues related to SQL see the SQL Issues chapter.

                Mode of Operation and Tables

                HSQLDB has many modes of operation and features that allow it to be used in very different scenarios. Levels of memory usage, speed and accessibility by different applications are influenced by how HSQLDB is deployed.

                Mode of Operation

                The decision to run HSQLDB as a separate server process or as an in-process database should be based on the following:

                • When HSQLDB is run as a server on a separate machine, it is isolated from hardware failures and crashes on the hosts running the application.

                • When HSQLDB is run as a server on the same machine, it is isolated from application crashes and memory leaks.

                • Server connections are slower than in-process connections due to the overhead of streaming the data for each JDBC call.

                Tables

                TEXT tables are designed for special applications where the data has to be in an interchangeable format, such as CSV. TEXT tables should not be used for routine storage of data.

                MEMORY tables and CACHED tables are generally used for data storage. The difference between the two is as follows:

                • The data for all MEMORY tables is read from the .script file when the database is started and stored in memory. In contrast the data for cached tables is not read into memory until the table is accessed. Furthermore, only part of the data for each CACHED table is held in memory, allowing tables with more data than can be held in memory.

                • When the database is shutdown in the normal way, all the data for MEMORY tables is written out to the disk. In comparison, the data in CACHED tables that has changed is written out at shutdown, plus a compressed backup of all the data in all cached tables.

                • The size and capacity of the data cache for all the CACHED tables is configurable. This makes it possible to allow all the data in CACHED tables to be cached in memory. In this case, speed of access is good, but slightly slower than MEMORY tables.

                • For normal applications it is recommended that MEMORY tables are used for small amounts of data, leaving CACHED tables for large data sets. For special applications in which speed is paramount and a large amount of free memory is available, MEMORY tables can be used for large tables as well

                Large Objects

                JDBC Clobs are supported as columns of the type LONGVARCHAR. JDBC Blobs are supported as columns of the type LONGVARBINARY. When large objects (LONGVARCHAR, LONGVARBINARY, OBJECT) are stored with table definitions that contain several normal fields, it is better to use two tables instead. The first table to contain the normal fields and the second table to contain the large object plus an identity field. Using this method has two benefits. (a) The first table can usually be created as a MEMORY table while only the second table is a CACHED table. (b) The large objects can be retrieved individually using their identity, instead of getting loaded into memory for finding the rows during query processing. An example of two tables and a select query that exploits the separation between the two follows:

                CREATE MEMORY TABLE MAINTABLE(MAINID INTEGER, ......);
                CREATE CACHED TABLE LOBTABLE(LOBID INTEGER, LOBDATA LONGVARBINARY);
                SELECT * FROM (SELECT * FROM MAINTABLE <join any other table> WHERE <various conditions apply>) JOIN LOBTABLE ON MAINID=LOBID;

                The inner SELECT finds the required rows without reference to the LOBTABLE and when it has found all the rows, retrieves the required large objects from the LOBTABLE.

                Deployment context

                The files used for storing HSQLDB database data are all in the same directory. New files are always created and deleted by the database engine. Two simple principles must be observed:

                • The Java process running HSQLDB must have full privileges on the directory where the files are stored. This include create and delete privileges.

                • The file system must have enough spare room both for the 'permanent' and 'temporary' files. The default maximum size of the .log file is 200MB. The .data file can grow to up to 8GB. The .backup file can be up to 50% of the .data file. The temporary file created at the time of a SHUTDOWN COMPACT can be equal in size to the .data file.

                Memory and Disk Use

                Memory used by the program can be thought of as two distinct pools: memory used for table data, and memory used for building result sets and other internal operations. In addition, when transactions are used, memory is utilised for storing the information needed for a rollback.

                Since version 1.7.1, memory use has been significantly reduced compared to previous versions. The memory used for a MEMORY table is the sum of memory used by each row. Each MEMORY table row is a Java object that has 2 int or reference variables. It contains an array of objects for the fields in the row. Each field is an object such as Integer, Long, String, etc. In addition each index on the table adds a node object to the row. Each node object has 6 int or reference variables. As a result, a table with just one column of type INTEGER will have four objects per row, with a total of 10 variables of 4 bytes each - currently taking up 80 bytes per row. Beyond this, each extra column in the table adds at least a few bytes to the size of each row.

                The memory used for a result set row has fewer overheads (fewer variables and no index nodes) but still uses a lot of memory. All the rows in the result set are built in memory, so very large result sets may not be possible. In server mode databases, the result set memory is released from the server once the database server has returned the result set. In-process databases release the memory when the application program releases the java.sql.ResultSet object. Server modes require additional memory for returning result sets, as they convert the full result set into an array of bytes which is then transmitted to the client.

                When UPDATE and DELETE queries are performed on CACHED tables, the full set of rows that are affected, including those affected due to ON UPDATE actions, is held in memory for the duration of the operation. This means it may not be possible to perform deletes or updates involving very large numbers of rows of CACHED tables. Such operations should be performed in smaller sets.

                When transactions support is enabled with SET AUTOCOMMIT OFF, lists of all insert, delete or update operations are stored in memory so that they can be undone when ROLLBACK is issued. Transactions that span hundreds of modification to data will take up a lot of memory until the next COMMIT or ROLLBACK clears the list.

                Most JVM implementations allocate up to a maximum amount of memory (usually 64 MB by default). This amount is generally not adequate when large memory tables are used, or when the average size of rows in cached tables is larger than a few hundred bytes. The maximum amount of allocated memory can be set on the java ... command line that is used for running HSQLDB. For example, with Sun JVM version 1.3.0 the parameter -Xmx256m increases the amount to 256 MB.

                1.8.0 uses a fast cache for immutable objects such as Integer or String that are stored in the database. In most circumstances, this reduces the memory footprint still further as fewer copies of the most frequently-used objects are kept in memory.

                Cache Memory Allocation

                With CACHED tables, the data is stored on disk and only up to a maximum number of rows are held in memory at any time. The default is up to 3*16384 rows. The hsqldb.cache_scale database property can be set to alter this amount. As any random subset of the rows in any of the CACHED tables can be held in the cache, the amount of memory needed by cached rows can reach the sum of the rows containing the largest field data. For example if a table with 100,000 rows contains 40,000 rows with 1,000 bytes of data in each row and 60,000 rows with 100 bytes in each, the cache can grow to contain nearly 50,000 rows, including all the 40,000 larger rows.

                An additional property, hsqldb.cache_size_scale can be used in conjunction with the hsqldb.cache_scale property. This puts a limit in bytes on the total size of rows that are cached. When the default values is used for both properties, the limit on the total size of rows is approximately 50MB. (This is the size of binary images of the rows and indexes. It translates to more actual memory, typically 2-4 times, used for the cache because the data is represented by Java objects.)

                If memory is limited, the hsqldb.cache_scale or hsqldb.cache_size_scale database properties can be reduced. In the example above, if the hsqldb.cache_size_scale is reduced from 10 to 8, then the total binary size limit is reduced from 50MB to 12.5 MB. This will allow the number of cached rows to reach 50,000 small rows, but only 12,500 of the larger rows.

                Managing Database Connections

                In all running modes (server or in-process) multiple connections to the database engine are supported. In-process (standalone) mode supports connections from the client in the same Java Virtual Machine, while server modes support connections over the network from several different clients.

                Connection pooling software can be used to connect to the database but it is not generally necessary. With other database engines, connection pools are used for reasons that may not apply to HSQLDB.

                • To allow new queries to be performed while a time-consuming query is being performed in the background. This is not possible with HSQLDB 1.8.0 as it blocks while performing the first query and deals with the next query once it has finished it. This capability is under development and will be introduced in a future version.

                • To limit the maximum number of simultaneous connections to the database for performance reasons. With HSQLDB this can be useful only if your application is designed in a way that opens and closes connections for each small task.

                • To control transactions in a multi-threaded application. This can be useful with HSQLDB as well. For example, in a web application, a transaction may involve some processing between the queries or user action across web pages. A separate connection should be used for each HTTP session so that the work can be committed when completed or rolled back otherwise. Although this usage cannot be applied to most other database engines, HSQLDB is perfectly capable of handling over 100 simultaneous HTTP sessions as individual JDBC connections.

                An application that is not both multi-threaded and transactional, such as an application for recording user login and logout actions, does not need more than one connection. The connection can stay open indefinitely and reopened only when it is dropped due to network problems.

                When using an in-process database with versions prior to 1.7.2 the application program had to keep at least one connection to the database open, otherwise the database would have been closed and further attempts to create connections could fail. This is not necessary since 1.7.2, which does not automatically close an in-process database that is opened by establishing a connection. An explicit SHUTDOWN command, with or without an argument, is required to close the database. In version 1.8.0 a connection property can be used to revert to the old behaviour.

                When using a server database (and to some extent, an in-process database), care must be taken to avoid creating and dropping JDBC Connections too frequently. Failure to observe this will result in unsuccessful connection attempts when the application is under heavy load.

                Upgrading Databases

                Any database not produced with the release version of HSQLDB 1.8.0 must be upgraded to this version. This includes databases created with the RC versions of 1.8.0. The instructions under the Upgrading Using the SCRIPT Command section should be followed in all cases.

                Once a database is upgraded to 1.8.0, it can no longer be used with Hypersonic or previous versions of HSQLDB.

                There may be some potential legacy issues in the upgrade which should be resolved by editing the .script file:

                • Version 1.8.0 does not accept duplicate names for indexes that were allowed before 1.7.2.

                • Version 1.8.0 does not accept duplicate names for table columns that were allowed before 1.7.0.

                • Version 1.8.0 does not create the same type of index for foreign keys as versions before 1.7.2.

                • Version 1.8.0 does not accept table or column names that are SQL identifiers without double quoting.

                Upgrading Using the SCRIPT Command

                To upgrade from 1.7.2 or 1.7.3 to 1.8.0, simply issue the SET SCRIPTFORMAT TEXT and SHUTDOWN SCRIPT commands with the old version, then open with the new version of the engine. The upgrade is then complete.

                To upgrade from older version database files (1.7.1 and older) that do not contain CACHED tables, simple SHUTDOWN with the older version and open with the new version. If there is any error in the .script file, try again after editing the .script file.

                To upgrade from older version database files (1.7.1 and older) that contain CACHED tables, use the SCRIPT procedure below. In all versions of HSQLDB and Hypersonic 1.43, the SCRIPT 'filename' command (used as an SQL query) allows you to save a full record of your database, including database object definitions and data, to a file of your choice. You can export a script file using the old version of the database engine and open the script as a database with 1.8.0.

                Procedure 5.1. Upgrade Using SCRIPT procedure

                1. Open the original database in the old version of DatabaseManager

                2. Issue the SCRIPT command, for example SCRIPT 'newversion.script' to create a script file containing a copy of the database.

                3. Use the 1.8.0 version of DatabaseManager to create a new database, in this example 'newversion' in a different directory.

                4. SHUTDOWN this database.

                5. Copy the newversion.script file from step 2 over the file of the same name for the new database created in 4.

                6. Try to open the new database using DatabaseManager.

                7. If there is any inconsistency in the data, the script line number is reported on the console and the opening process is aborted. Edit and correct any problems in the newversion.script before attempting to open again. Use the guidelines in the next section (Manual Changes to the .script File). Use a programming editor that is capable of handling very large files and does not wrap long lines of text.

                Manual Changes to the .script File

                In 1.8.0 the full range of ALTER TABLE commands is available to change the data structures and their names. However, if an old database cannot be opened due to data inconsistencies, or the use of index or column names that are not compatible with 1.8.0, manual editing of the SCRIPT file can be performed.

                The following changes can be applied so long as they do not affect the integrity of existing data.

                • Names of tables, columns and indexes can be changed.

                • CREATE UNIQUE INDEX ... to CREATE INDEX ... and vice versa

                  A unique index can always be converted into a normal index. A non-unique index can only be converted into a unique index if the table data for the column(s) is unique in each row.

                • NOT NULL

                  A not-null constraint can always be removed. It can only be added if the table data for the column has no null values.

                • PRIMARY KEY

                  A primary key constraint can be removed or added. It cannot be removed if there is a foreign key referencing the column(s).

                • COLUMN TYPES

                  Some changes to column types are possible. For example an INTEGER column can be changed to BIGINT, or DATE, TIME and TIMESTAMP columns can be changed to VARCHAR.

                After completing the changes and saving the modified *.script file, you can open the database as normal.

                Backing Up Databases

                The data for each database consists of up to 5 files in the same directory. The endings are *.properties, *.script, *.data, *.backup and *.log (a file with the *.lck ending is used for controlling access to the database and should not be backed up). These should be backed up together. The files can be backed up while the engine is running but care should be taken that a CHECKPOINT or SHUTDOWN operation does not take place during the backup. It is more efficient to perform the backup immediately after a CHECKPOINT. The *.data file can be excluded from the backup. In this case, when restoring, a dummy *.data file is needed which can be an empty, 0 length file. The engine will expand the *.backup file to replace this dummy file if the backup is restored. If the *.data file is not backed up, the *.properties file may have to be modified to ensure it contain modified=yes instead of modified=no prior to restoration. If a backup immediately follows a checkpoint, then the *.log file can also be excluded, reducing the significant files to *.properties, *.script and *.backup. Normal backup methods, such as archiving the files in a compressed bundle can be used.

                Purpose

                Many questions repeatedly asked in Forums and mailing lists are answered in this guide. If you want to use HSQLDB with your application, you should read this guide.

                SQL Standard Support

                HSQLDB 1.8.0 supports the dialect of SQL defined by SQL standards 92, 99 and 2003. This means where a feature of the standard is supported, e.g. left outer join, the syntax is that specified by the standard text. Many features of SQL92 and 99 up to Advanced Level are supported and there is support for most of SQL 2003 Foundation and several optional features of this standard. However, certain features of the Standards are not supported so no claim is made for full support of any level of the standards.

                The SQL Syntax chapter of this guide SQL Syntax lists all the keywords and syntax that is supported. When writing or converting existing SQL DDL (Data Definition Language) and DML (Data Manipulation Language) statements for HSQLDB, you should consult the supported syntax and modify the statements accordingly.

                Several words are reserved by the standard and cannot be used as table or column names. For example, the word POSITION is reserved as it is a function defined by the Standards with a similar role as String.indexOf() in Java. HSQLDB does not currently prevent you from using a reserved word if it does not support its use or can distinguish it. For example BEGIN is a reserved words that is not currently supported by HSQLDB and is allowed as a table or column name. You should avoid the use of such words as future versions of HSQLDB are likely to support the words and will reject your table definitions or queries. The full list of SQL reserved words is in the source of the org.hsqldb.Token class.

                HSQLDB also supports some keywords and expressions that are not part of the SQL standard as enhancements. Expressions such as SELECT TOP 5 FROM .., SELECT LIMIT 0 10 FROM ... or DROP TABLE mytable IF EXISTS are among such constructs.

                All keywords, can be used for database objects if they are double quoted.

                Constraints and Indexes

                Primary Key Constraints

                Before 1.7.0, a CONSTRAINT <name> PRIMARY KEY was translated internally to a unique index and, in addition, a hidden column was added to the table with an extra unique index. From 1.7.0 both single-column and multi-column PRIMARY KEY constraints are supported. They are supported by a unique index on the primary key column(s) specified and no extra hidden column is maintained for these indexes.

                Unique Constraints

                According to the SQL standards, a unique constraint on a single column means no two values are equal unless one of them is NULL. This means you can have one or more rows where the column value is NULL.

                A unique constraint on multiple columns (c1, c2, c3, ..) means that no two sets of values for the columns are equal unless at lease one of them is NULL. Each single column taken by itself can have repeat values. The following example satisfies a UNIQUE constraint on the two columns:

                Example 2.1. Column values which satisfy a 2-column UNIQUE constraint

                1,2
                2,1
                2,2
                NULL,1
                NULL,1
                1,NULL
                NULL,NULL
                NULL,NULL

                Since version 1.7.2 the behaviour of UNIQUE constraints and indexes with respect to NULL values has changed to conform to SQL standards. A row, in which the value for any of the UNIQUE constraint columns is NULL, can always be added to the table. So multiple rows can contain the same values for the UNIQUE columns if one of the values is NULL.

                Unique Indexes

                In 1.8.0, user defined UNIQUE indexes can still be declared but they are deprecated. You should use a UNIQUE constraint instead.

                CONSTRAINT <name> UNIQUE always creates internally a unique index on the columns, as with previous versions, so it has exactly the same effect as the deprecated UNIQUE index declaration.

                FOREIGN KEYS

                From version 1.7.0, HSQLDB features single and multiple column foreign keys. A foreign key can also be specified to reference a target table without naming the target column(s). In this case the primary key column(s) of the target table is used as the referenced column(s). Each pair of referencing and referenced columns in any foreign key should be of identical type. When a foreign key is declared, a unique constraint (or primary key) must exist on the referenced columns in the primary key table. A non-unique index is automatically created on the referencing columns. For example:

                    CREATE TABLE child(c1 INTEGER, c2 VARCHAR, FOREIGN KEY (c1, c2) REFERENCES parent(p1, p2));

                There must be a UNIQUE constraint on columns (p1,p2) in the table named "parent". A non-unique index is automatically created on columns (c1, c2) in the table named "child". Columns p1 and c1 must be of the same type (INTEGER). Columns p2 and c2 must be of the same type (VARCHAR).

                Indexes and Query Speed

                HSQLDB does not use indexes to improve sorting of query results. But indexes have a crucial role in improving query speed. If no index is used in a query on a single table, such as a DELETE query, then all the rows of the table must be examined. With an index on one of the columns that is in the WHERE clause, it is often possible to start directly from the first candidate row and reduce the number of rows that are examined.

                Indexes are even more important in joins between multiple tables. SELECT ... FROM t1 JOIN t2 ON t1.c1 = t2.c2 is performed by taking rows of t1 one by one and finding a matching row in t2. If there is no index index on t2.c2 then for each row of t1, all the rows of t2 must be checked. Whereas with an index, a matching row can be found in a fraction of the time. If the query also has a condition on t1, e.g., SELECT ... FROM t1 JOIN t2 ON t1.c1 = t2.c2 WHERE t1.c3 = 4 then an index on t1.c3 would eliminate the need for checking all the rows of t1 one by one, and will reduce query time to less than a millisecond per returned row. So if t1 and t2 each contain 10,000 rows, the query without indexes involves checking 100,000,000 row combinations. With an index on t2.c2, this is reduced to 10,000 row checks and index lookups. With the additional index on t2.c2, only about 4 rows are checked to get the first result row.

                Indexes are automatically created for primary key and unique columns. Otherwise you should define an index using the CREATE INDEX command.

                Note that in HSQLDB a unique index on multiple columns can be used internally as a non-unique index on the first column in the list. For example: CONSTRAINT name1 UNIQUE (c1, c2, c3); means there is the equivalent of CREATE INDEX name2 ON atable(c1);. So you do not need to specify an extra index if you require one on the first column of the list.

                In 1.8.0, a multi-column index will speed up queries that contain joins or values on ALL the columns. You need NOT declare additional individual indexes on those columns unless you use queries that search only on a subset of the columns. For example, rows of a table that has a PRIMARY KEY or UNIQUE constraint on three columns or simply an ordinary index on those columns can be found efficiently when values for all three columns are specified in the WHERE clause. For example, SELECT ... FROM t1 WHERE t1.c1 = 4 AND t1.c2 = 6 AND t1.c3 = 8 will use an index on t1(c1,c2,c3) if it exists.

                As a result of the improvements to multiple key indexes, the order of declared columns of the index or constraint has less affect on the speed of searches than before. If the column that contains more diverse values appears first, the searches will be slightly faster.

                A multi-column index will not speed up queries on the second or third column only. The first column must be specified in the JOIN .. ON or WHERE conditions.

                Query speed depends a lot on the order of the tables in the JOIN .. ON or FROM clauses. For example the second query below should be faster with large tables (provided there is an index on TB.COL3). The reason is that TB.COL3 can be evaluated very quickly if it applies to the first table (and there is an index on TB.COL3):

                    (TB is a very large table with only a few rows where TB.COL3 = 4)

    SELECT * FROM TA JOIN TB ON TA.COL1 = TB.COL2 AND TB.COL3 = 4;

    SELECT * FROM TB JOIN TA ON TA.COL1 = TB.COL2 AND TB.COL3 = 4;

                The general rule is to put first the table that has a narrowing condition on one of its columns.

                1.7.3 features automatic, on-the-fly indexes for views and subselects that are used in a query. An index is added to a view when it is joined to a table or another view.

                Where Condition or Join

                Using WHERE conditions to join tables is likely to reduce execution speed. For example the following query will generally be slow, even with indexes:

                    SELECT ... FROM TA, TB, TC WHERE TC.COL3 = TA.COL1 AND TC.COL3=TB.COL2 AND TC.COL4 = 1

                The query implies TA.COL1 = TB.COL2 but does not explicitly set this condition. If TA and TB each contain 100 rows, 10000 combinations will be joined with TC to apply the column conditions, even though there may be indexes on the joined columns. With the JOIN keyword, the TA.COL1 = TB.COL2 condition has to be explicit and will narrow down the combination of TA and TB rows before they are joined with TC, resulting in much faster execution with larger tables:

                    SELECT ... FROM TA JOIN TB ON TA.COL1 = TB.COL2 JOIN TC ON TB.COL2 = TC.COL3 WHERE TC.COL4 = 1

                The query can be speeded up a lot more if the order of tables in joins are changed, so that TC.COL1 = 1 is applied first and a smaller set of rows are joined together:

                    SELECT ... FROM TC JOIN TB ON TC.COL3 = TB.COL2 JOIN TA ON TC.COL3 = TA.COL1 WHERE TC.COL4 = 1

                In the above example the engine automatically applies TC.COL4 = 1 to TC and joins only the set of rows that satisfy this condition with other tables. Indexes on TC.COL4, TB.COL2 and TA.COL1 will be used if present and will speed up the query.

                Subqueries and Joins

                Using joins and setting up the order of tables for maximum performance applies to all areas. For example, the second query below should generally be much faster if there are indexes on TA.COL1 and TB.COL3:

                Example 2.2. Query comparison

                    SELECT ... FROM TA WHERE TA.COL1 = (SELECT MAX(TB.COL2) FROM TB WHERE TB.COL3 = 4)

    SELECT ... FROM (SELECT MAX(TB.COL2) C1 FROM TB WHERE TB.COL3 = 4) T2 JOIN TA ON TA.COL1 = T2.C1

                The second query turns MAX(TB.COL2) into a single row table then joins it with TA. With an index on TA.COL1, this will be very fast. The first query will test each row in TA and evaluate MAX(TB.COL2) again and again.

                Types and Arithmetic Operations

                Table columns of all types supported by HSQLDB can be indexed and can feature in comparisons. Types can be explicitly converted using the CONVERT() library function, but in most cases they are converted automatically. It is recommended not to use indexes on LONGVARBINARY, LONGVARCHAR and OTHER columns, as these indexes will probably not be allowed in future versions.

                Previous versions of HSQLDB featured poor handling of arithmetic operations. For example, it was not possible to insert 10/2.5 into any DOUBLE or DECIMAL column. Since 1.7.0, full operations are possible with the following rules:

                TINYINT, SMALLINT, INTEGER, BIGINT, NUMERIC and DECIMAL (without a decimal point) are supported integral types and map to byte, short, int, long and BigDecimal in Java. The SQL type dictates the maximum and minimum values that can be held in a field of each type. For example the value range for TINYINT is -128 to +127, although the actual Java type used for handling TINYINT is java.lang.Integer.

                REAL, FLOAT, DOUBLE are all mapped to double in Java.

                DECIMAL and NUMERIC are mapped to java.math.BigDecimal and can have very large numbers of digits.

                Integral Types

                TINYINT, SMALLINT, INTEGER, BIGINT, NUMERIC and DECIMAL (without a decimal point) are fully interchangeable internally, and no data narrowing takes place. Depending on the types of the operands, the result of the operations is returned in a JDBC ResultSet in any of related Java types: Integer, Long or BigDecimal. The ResultSet.getXXXX() methods can be used to retrieve the values so long as the returned value can be represented by the resulting type. This type is deterministically based on the query, not on the actual rows returned. The type does not change when the same query that returned one row, returns many rows as a result of adding more data to the tables.

                If the SELECT statement refers to a simple column or function, then the return type is the type corresponding to the column or the return type of the function. For example:

                    CREATE TABLE t(a INTEGER, b BIGINT); SELECT MAX(a), MAX(b) FROM t;

                would return a result set where the type of the first column is java.lang.Integer and the second column is java.lang.Long. However,

                    SELECT MAX(a) + 1, MAX(b) + 1 FROM t;

                would return java.lang.Long and BigDecimal values, generated as a result of uniform type promotion for all the return values.

                There is no built-in limit on the size of intermediate integral values in expressions. As a result, you should check for the type of the ResultSet column and choose an appropriate getXXXX() method to retrieve it. Alternatively, you can use the getObject() method, then cast the result to java.lang.Number and use the intValue() or longValue() methods on the result.

                When the result of an expression is stored in a column of a database table, it has to fit in the target column, otherwise an error is returned. For example when 1234567890123456789012 / 12345687901234567890 is evaluated, the result can be stored in any integral type column, even a TINYINT column, as it is a small value.

                Other Numeric Types

                In SQL statements, numbers with a decimal point are treated as DECIMAL unless they are written with an exponent. Thus 0.2 is considered a DECIMAL value but 0.2E0 is considered a DOUBLE value.

                When PreparedStatement.setDouble() or setFloat() is used, the value is treated as a DOUBLE automatically.

                When a REAL, FLOAT or DOUBLE (all synonymous) is part of an expression, the type of the result is DOUBLE.

                Otherwise, when no DOUBLE value exists, if a DECIMAL or NUMERIC value is part an expression, the type of the result is DECIMAL. The result can be retrieved from a ResultSet in the required type so long as it can be represented. This means DECIMAL values can be converted to DOUBLE unless they are beyond the Double.MIN_VALUE - Double.MAX_VALUE range. Similar to integral values, when the result of an expression is stored in a table column, it has to fit in the target column, otherwise an error is returned.

                The distinction between DOUBLE and DECIMAL is important when a division takes place. When the terms are DECIMAL, the result is a value with a scale (number of digits to the right of the decimal point) equal to the larger of the scales of the two terms. With a DOUBLE term, the scale will reflect the actual result of the operation. For example, 10.0/8.0 (DECIMAL) equals 1.2 but 10.0E0/8.0E0 (DOUBLE) equals 1.25. Without division operations, DECIMAL values represent exact arithmetic; the resulting scale is the sum of the scales of the two terms when multiplication is performed.

                REAL, FLOAT and DOUBLE values are all stored in the database as java.lang.Double objects. Special values such as NaN and +-Infinity are also stored and supported. These values can be submitted to the database via JDBC PreparedStatement methods and are returned in ResultSet objects.

                Bit and Boolean Types

                Since 1.7.2, BIT is simply an alias for BOOLEAN. The primary representation of BOOLEAN column is 'true' or 'false' either as the boolean type or as strings when used from JDBC. This type of column can also be initialised using values of any numeric type. In this case 0 is translated to false and any other value such as 1 is translated to true.

                Since 1.7.3 the BOOLEAN type conforms to the SQL standards and supports the UNDEFINED state in addition to TRUE or FALSE. NULL values are treated as undefined. This improvement affects queries that contain NOT IN. See the test text file, TestSelfNot.txt, for examples of the queries.

                Storage and Handling of Java Objects

                Since version 1.7.2 this support has improved and any serializable JAVA Object can be inserted directly into a column of type OTHER using any variation of PreparedStatement.setObject() methods.

                For comparison purposes and in indexes, any two Java Objects are considered equal unless one of them is NULL. You cannot search for a specific object or perform a join on a column of type OTHER.

                Please note that HSQLDB is not an object-relational database. Java Objects can simply be stored internally and no operations should be performed on them other than assignment between columns of type OTHER or tests for NULL. Tests such as WHERE object1 = object2, or WHERE object1 = ? do not mean what you might expect, as any non-null object would satisfy such a tests. But WHERE object1 IS NOT NULL is perfectly acceptable.

                The engine does not return errors when normal column values are assigned to Java Object columns (for example assigning an INTEGER or STRING to such a column with an SQL statement such as UPDATE mytable SET objectcol = intcol WHERE ...) but this is highly likely to be disallowed in future. So please use columns of type OTHER only to store your objects and nothing else.

                Type Size, Precision and Scale

                Prior to 1.7.2, all table column type definitions with a column size, precision or scale qualifier were accepted and ignored.

                In 1.8.0, such qualifiers must conform to the SQL standards. For example INTEGER(8) is no longer acceptable. The qualifiers are still ignored unless you set a database property. SET PROPERTY "sql.enforce_strict_size" TRUE will enforce sizes for CHARACTER or VARCHAR columns and pad any strings when inserting or updating a CHARACTER column. The precision and scale qualifiers are also enforced for DECIMAL and NUMERIC types. TIMESTAMP can be used with a precision of 0 or 6 only.

                Casting a value to a qualified CHARACTER type will result in truncation or padding as you would expect. So a test such as CAST (mycol AS VARCHAR(2)) = 'xy' will find the values beginning with 'xy'. This is the equivalent of SUBSTRING(mycol FROM 1 FOR 2) = 'xy'.

                Sequences and Identity

                The SEQUENCE keyword was introduced in 1.7.2 with a subset of the SQL 200n standard syntax. Corresponding SQL 200n syntax for IDENTITY columns has also been introduced.

                Identity Auto-Increment Columns

                Each table can contain one auto-increment column, known as the IDENTITY column. An IDENTITY column is always treated as the primary key for the table (as a result, multi-column primary keys are not possible with an IDENTITY column present). Support has been added for CREATE TABLE <tablename>(<colname> IDENTITY, ...) as a shortcut.

                Since 1.7.2, the SQL standard syntax is used by default, which allows the initial value to be specified. The supported form is(<colname> INTEGER GENERATED BY DEFAULT AS IDENTITY(START WITH n, [INCREMENT BY m])PRIMARY KEY, ...). Support has also been added for BIGINT identity columns. As a result, an IDENTITY column is simply an INTEGER or BIGINT column with its default value generated by a sequence generator.

                When you add a new row to such a table using an INSERT INTO <tablename> ...; statement, you can use the NULL value for the IDENTITY column, which results in an auto-generated value for the column. The IDENTITY() function returns the last value inserted into any IDENTITY column by this connection. Use CALL IDENTITY(); as an SQL statement to retrieve this value. If you want to use the value for a field in a child table, you can use INSERT INTO <childtable> VALUES (...,IDENTITY(),...);. Both types of call to IDENTITY() must be made before any additional update or insert statements are issued on the database.

                The next IDENTITY value to be used can be set with the 

                ALTER TABLE ALTER COLUMN <column name> RESTART WITH <new value>;

                Sequences

                The SQL 200n syntax and usage is different from what is supported by many existing database engines. Sequences are created with the CREATE SEQUENCE command and their current value can be modified at any time with ALTER SEQUENCE. The next value for a sequence is retrieved with the NEXT VALUE FOR <name> expression. This expression can be used for inserting and updating table rows. You can also use it in select statements. For example, if you want to number the returned rows of a SELECT in sequential order, you can use:

                Example 2.3. Numbering returned rows of a SELECT in sequential order

                    SELECT NEXT VALUE FOR mysequence, col1, col2 FROM mytable WHERE ...

                Please note that the semantics of sequences is not exactly the same as defined by SQL 200n. For example if you use the same sequence twice in the same row insert query, you will get two different values, not the same value as required by the standard.

                You can query the SYSTEM_SEQUENCES table for the next value that will be returned from any of the defined sequences. The SEQUENCE_NAME column contains the name and the NEXT_VALUE column contains the next value to be returned.

                Issues with Transactions

                HSQLDB supports transactions at the READ_UNCOMMITTED level, also known as level 0 transaction isolation. This means that during the lifetime of a transaction, other connections to the database can see the changes made to the data. Transaction support works well in general. Reported bugs concerning transactions being committed if the database is abruptly closed have been fixed. However, the following issues may be encountered only with multiple connections to a database using transactions:

                If two transactions modify the same row, no exception is raised when both transactions are committed. This can be avoided by designing your database in such a way that application data consistency does not depend on exclusive modification of data by one transaction. You can set a database property to cause an exception when this happens.

                SET PROPERTY "sql.tx_no_multi_rewrite" TRUE
                When an ALTER TABLE .. INSERT COLUMN or DROP COLUMN command results in changes to the table structure, the current session is committed. If an uncommitted transaction started by another connections has changed the data in the affected table, it may not be possible to roll it back after the ALTER TABLE command. This may also apply to ADD INDEX or ADD CONSTRAINT commands. It is recommended to use these ALTER commands only when it is known that other connections are not using transactions.

                After a CHECKPOINT command is issued, uncommitted transactions can be continued, committed, or rolled back. However, if the database is not subsequently closed properly with the SHUTDOWN command, any such transaction that still remains uncommitted at the time of shutdown, is part committed (to the state at CHECKPOINT) at the next startup. It is recommended to use the CHECKPOINT command either when no uncommitted transactions is in progress, or it is known that any such transaction is not likely to last for such a long time that an abnormal shutdown might affect its data.

                New Features and Changes

                In recent versions leading to 1.8.0 many enhancements were made for better SQL support. These are listed in the SQL Syntax chapter, in ../changelog_1_8_0.txt and ../changelog_1_7_2.txt. Functions and expressions such as POSITION(), SUBSTRING(), NULLIF(), COALESCE(), CASE ... WHEN .. ELSE, ANY, ALL etc. are among them. Other enhancements may not be very obvious in the documentation but can result in changes of behaviour from previous versions. Most significant among these are handling of NULL values in joins (null columns are no longer joined) and OUTER joins (the results are now correct). You should test your applications with the new version to ensure they do not rely on past incorrect behaviour of the engine. The engine will continue to evolve in future versions towards full SQL standard support, so it is best not to rely on any non-standard feature of the current version.

                Brief Introduction

                Brief Introduction

                Transfer Tool is a GUI program for transferring SQL schema and data from one JDBC source to another. Source and destination can be different database engines or different databases on the same server.

                Transfer Tool works in two different modes. Direct transfer maintains a connection to both source and destination and performs the transfer. Dump and Restore mode is invoked once to transfer the data from the source to a text file (Dump), then again to transfer the data from the text file to the destination (Restore). With Dump and Restore, it is possible to make any changes to database object definitions and data prior to restoring it to the target.

                Dump and Restore modes can be set via the command line with -d (--dump) or -r (--restore) options. Alternatively the Transfer Tool can be started with any of the three modes from the Database Manager's Tools menu.

                The connection dialogue allows you to save the settings for the connection you are about to make. You can then access the connection in future sessions. These settings are shared with those from the Database Manager tool. See the appendix on Database Manager for details of the connection dialogue box.

                In version 1.8.0 Transfer Tool is no longer part of the hsqldb.jar. You can build the hsqldbutil.jar using the Ant command of the same name, to build a jar that includes Transfer Tool and the Database Manager.

                When collecting meta-data, Transfer Tool performs SELECT * FROM <table> queries on all the tables in the source database. This may take a long time with some database engines. When the source database is HSQLDB, this means memory should be available for the result sets returned from the queries. Therefore, the memory allocation of the java process in which Transfer Tool is executed may have to be high.

                Importing from a Text Table file

                Text Table support for HSQLDB was originally developed by Bob Preston independently from the Project. Subsequently Bob joined the Project and incorporated this feature into version 1.7.0, with a number of enhancements, especially the use of conventional SQL commands for specifying the files used for Text Tables.

                In a nutshell, Text Tables are CSV or other delimited files treated as SQL tables. Any ordinary CSV or other delimited file can be used. The full range of SQL queries can be performed on these files, including SELECT, INSERT, UPDATE and DELETE. Indexes and unique constraints can be set up, and foreign key constraints can be used to enforce referential integrity between Text Tables themselves or with conventional tables.

                HSQLDB with Text Table support is the only comprehensive solution that employs the power of SQL and the universal reach of JDBC to handle data stored in text files and will have wide-ranging use way beyond the currently established Java realm of HSQLDB.

                Goals of the Implementation

                1. We aimed to finalise the DDL for Text Tables so that future releases of HSQLDB use the same DDL scripts.

                2. We aimed to support Text Tables as GLOBAL TEMPORARY or GLOBAL BASE tables in the SQL domain.

                The Implementation

                Definition of Tables

                Text Tables are defined similarly to conventional tables with the added TEXT keyword:

                    CREATE TEXT TABLE <tablename> (<column definition> [<constraint definition>])

                In addition, a SET command specifies the file and the separator character that the Text table uses:

                    SET TABLE <tablename> SOURCE <quoted_filename_and_options> [DESC]

                Text Tables cannot be created in memory-only databases (databases that have no script file).

                Scope and Reassignment

                • A Text table without a file assigned to it is READ ONLY and EMPTY.

                • A Temporary Text table has the scope and the lifetime of the SQL session (a JDBC Connection).

                • Reassigning a Text Table definition to a new file has implications in the following areas:

                  1. The user is required to be an administrator.

                  2. Existing transactions are committed at this point.

                  3. Constraints, including foreign keys referencing this table, are kept intact. It is the responsibility of the administrator to ensure their integrity.

                  From version 1.7.2 the new source file is scanned and indexes are built when it is assigned to the table. At this point any violation of NOT NULL, UNIQUE or PRIMARY KEY constrainst are caught and the assignment is aborted. However, foreign key constraints are not checked at the time of assignment or reassignment of the source file.

                Null Values in Columns of Text Tables

                This has changed since 1.7.2 to support both null values and empty strings.

                • Empty fields are treated as NULL. These are fields where there is nothing or just spaces between the separators.

                • Quoted empty strings are treated as empty strings.

                Configuration

                The default field separator is a comma (,). A different field separator can be specified within the SET TABLE SOURCE statement. For example, to change the field separator for the table mytable to a vertical bar, place the following in the SET TABLE SOURCE statement, for example:

                    SET TABLE mytable SOURCE "myfile;fs=|"

                Since HSQLDB treats CHAR's, VARCHARs, and LONGVARCHARs the same, the ability to assign different separators to the latter two is provided. When a different separator is assigned to a VARCHAR or LONGVARCHAR field, it will terminate any CSV field of that type. For example, if the first field is CHAR, and the second field LONGVARCHAR, and the separator fs has been defined as the pipe (|) and vs as the period (.) then the data in the CSV file for a row will look like:

                    First field data|Second field data.Third field data

                The following example shows how to change the default separator to the pipe (|), VARCHAR separator to the period (.) and the LONGVARCHAR separator to the tilde (~). Place the following within the SET TABLE SOURCE statement, for example:

                    SET TABLE mytable SOURCE "myfile;fs=|;vs=.;lvs=~"

                HSQLDB also recognises the following special indicators for separators:

                special indicators for separators

                \semi

                semicolon

                \quote

                qoute

                \space

                space character

                \apos

                apostrophe

                \n

                newline - Used as an end anchor (like $ in regular expressions)

                \r

                carriage return

                \t

                tab

                \\

                backslash

                \u####

                a Unicode character specified in hexadecimal

                Furthermore, HSQLDB provides csv file support with three additional boolean options: ignore_first, quoted and all_quoted. The ignore_first option (default false) tells HSQLDB to ignore the first line in a file. This option is used when the first line of the file contains column headings. The all_quoted option (default false) tells the program that it should use quotes around all character fields when writing to the source file. The quoted option (default true) uses quotes only when necessary to distinguish a field that contains the separator character. It can be set to false to prevent the use of quoting altogether and treat quote characters as normal characters. These options may be specified within the SET TABLE SOURCE statement:

                    SET TABLE mytable SOURCE "myfile;ignore_first=true;all_quoted=true"

                When the default options all_quoted= false and quoted=true are in force, fields that are written to a line of the csv file will be quoted only if they contain the separator or the quote character. The quote character is doubled when used inside a string. When all_quoted=false and quoted=false the quote character is not doubled. With this option, it is not possible to insert any string containing the separator into the table, as it would become impossible to distinguish from a separator. While reading an existing data source file, the program treats each individual field separately. It determines that a field is quoted only if the first character is the quote character. It interprets the rest of the field on this basis.

                The character encoding for the source file is ASCII by default. To support UNICODE or source files preprared with different encodings this can be changed to UTF-8 or any other encoding. The default is encoding=ASCII and the option encoding=UTF-8 or other supported encodings can be used.

                Finally, HSQLDB provides the ability to read a text file from the bottom up and making them READ ONLY, by placing the keyword "DESC" at the end of the SET TABLE SOURCE statement:

                    SET TABLE mytable SOURCE "myfile" DESC

                This feature provides functionality similar to the Unix tail command, by re-reading the file each time a select is executed. Using this feature sets the table to read-only mode. Afterwards, it will no longer be possible to change the read-only status with SET TABLE <tablename> READONLY TRUE.

                Text table source files are cached in memory. The maximum number of rows of data that are in memory at any time is controlled by the textdb.cache_scale property. The default value for textdb.cache_scale is 10 and can be changed by setting the property in the .properties file for the database. The number of rows in memory is calculated as 3*(2**scale), which translates to 3072 rows for the default textdb.cache_scale setting (10). The property can also be set for individual text tables:

                    SET TABLE mytable SOURCE "myfile;ignore_first=true;all_quoted=true;cache_scale=12"

                Disconnecting Text Tables

                The following describes behaviour present in 1.8.0.8 and later.

                Text tables may be disconnected from their underlying data source, i.e. the text file.

                You can explicitly disconnect a text table from its file by issuing the following statement: 

                  SET TABLE mytable SOURCE OFF

                Subsequently, mytable will be empty and read-only. However, the data source description will be preserved, and the table can be re-connected to it with 

                  SET TABLE mytable SOURCE ON

                When a database is opened, if the source file for an existing text table is missing the table remains disconnected from its data source, but the source sescription is preserved. This allows the missing source file to be added to the directory and the table re-connected to it with the above command.

                Text File Issues

                Text File Issues

                • File locations are restricted to below the directory that contains the database, unless the textdb.allow_full_path property is set true in the database properties file.

                • Blank lines are allowed anywhere in the text file, and are ignored.

                • The file location for a text table created with

                      SELECT <select list> INTO TEXT <tablename> FROM

                  is the directory that contains the database and the file name is based on the table name. The table name is converted into the file name by replacing all the non-alphanumeric characters with the underscore character, conversion into lowercase, and adding the ".csv" suffix.

                • It is possible to define a primay key or identity column for text tables.

                • When a table source file is used with the ignore_first=true option, the first, ignored line is replaced with a blank line after a SHUTDOWN COMPACT.

                • An existing table source file may include CHARACTER fields that do not begin with the quote character but contain instances of the quote character. These fields are read as literal strings. Alternatively, if any field begins with the quote character, then it is interpreted as a quoted string that should end with the quote character and any instances of the quote character within the string is doubled. When any field containing the quote character or the separator is written out to the source file by the program, the field is enclosed in quote character and any instance of the quote character inside the field is doubled.

                • Inserts or updates of CHARACTER type field values are allowed with strings that contains the linefeed or the carriage return character. This feature is disabled when both quoted and all_quoted properties are false.

                • ALTER TABLE commands that add or drop columns are not supported with non-empty text tables.

                Importing a Text Table file in to a Traditional (non-Text Table) Table

                The directory src/org/hsqldb/sample in your HSQLDB distibution contains a file named load_binding_lu.sql. This is a working SQL file which imports a pipe-delimited text file from the database's file directory into an existing normal table. You can edit a copy of this file and use it directly with SqlTool, or you can use the SQL therein as a model (using any SQL client at all).

                Purpose

                Many questions repeatedly asked in Forums and mailing lists are answered in this guide. If you want to use HSQLDB with your application, you should read this guide. This document covers system related issues. For issues related to SQL see the SQL Issues chapter.

                Connections

                The normal method of accessing an HSQLDB database is via the JDBC Connection interface. An introduction to different methods of providing database services and accessing them can be found in the SQL Issues chapter. Details and examples of how to connect via JDBC are provided in our JavaDoc for jdbcConnection.

                Version 1.7.2 introduced a uniform method of distinguishing between different types of connection, alongside new capabilities to provide access to multiple databases. The common driver identifier is jdbc:hsqldb: followed by a protocol identifier (mem: file: res: hsql: http: hsqls: https:) then followed by host and port identifiers in the case of servers, then followed by database identifier.

                Table 4.1. Hsqldb URL Components

                Driver and ProtocolHost and PortDatabase
                jdbc:hsqldb:mem:
                		not available
                accounts

                Lowercase, single-word identifier creates the in-memory database when the first connection is made. Subsequent use of the same Connection URL connects to the existing DB.

                The old form for the URL, jdbc:hsqldb:. creates or connects to the same database as the new form for the URL, jdbc:hsqldb:mem:.

                jdbc:hsqldb:file:
                		not available
                mydb
                /opt/db/accounts
                C:/data/mydb

                The file path specifies the database file. In the above examples the first one refers to a set of mydb.* files in the directory where the javacommand for running the application was issued. The second and third examples refer to absolute paths on the host machine.

                jdbc:hsqldb:res:
                		not available
                /adirectory/dbname
                Database files can be loaded from one of the jars specified as part of the Java command the same way as resource files are accessed in Java programs. The /adirectory above stands for a directory in one of the jars.
                jdbc:hsqldb:hsql:
                jdbc:hsqldb:hsqls:
                jdbc:hsqldb:http:
                jdbc:hsqldb:https:
                //localhost
                //192.0.0.10:9500
                //dbserver.somedomain.com
                /an_alias
                /enrollments
                /quickdb

                The host and port specify the IP address or host name of the server and an optional port number. The database to connect to is specified by an alias. This alias is a lowercase string defined in the server.properties file to refer to an actual database on the file system of the server or a transient, in-memory database on the server. The following example lines in server.properties or webserver.properties define the database aliases listed above and accessible to clients to refer to different file and in-memory databases.

                    database.0=file:/opt/db/accounts
    dbname.0=an_alias

    database.1=file:/opt/db/mydb
    dbname.1=enrollments

    database.2=mem:adatabase
    dbname.2=quickdb

                The old form for the server URL, e.g., jdbc:hsqldb:hsql//localhost connects to the same database as the new form for the URL, jdbc:hsqldb:hsql//localhost/ where the alias is a zero length string. In the example below, the database files lists.* in the /home/dbmaster/ directory are associated with the empty alias:

                    database.3=/home/dbmaster/lists
    dbname.3=

                Connection properties

                Each new JDBC Connection to a database can specify connection properties. The properties user and password are always required. In 1.8.0 the following optional properties can also be used.

                Connection properties are specified either by establishing the connection via the:

                    DriverManager.getConnection (String url, Properties info);

                method call, or the property can be appended to the full Connection URL.

                Table 4.2. Connection Properties

                get_column_nametruecolumn name in ResultSet

                This property is used for compatibility with other JDBC driver implementations. When true (the default), ResultSet.getColumnName(int c) returns the underlying column name

                When false, the above method returns the same value as ResultSet.getColumnLabel(int column) Example below:

                    jdbc:hsqldb:hsql://localhost/enrollments;get_column_name=false

                When a ResultSet is used inside a user-defined stored procedure, the default, true, is always used for this property.

                ifexistsfalseconnect only if database already exists

                Has an effect only with mem: and file: database. When true, will not create a new database if one does not already exist for the URL.

                When false (the default), a new mem: or file: database will be created if it does not exist.

                Setting the property to true is useful when troubleshooting as no database is created if the URL is malformed. Example below:

                    jdbc:hsqldb:file:enrollments;ifexists=true
                shutdownfalseshut down the database when the last connection is closed

                This mimics the behaviour of 1.7.1 and older versions. When the last connection to a database is closed, the database is automatically shut down. The property takes effect only when the first connection is made to the database. This means the connection that opens the database. It has no effect if used with subsequent, simultaneous connections.

                This command has two uses. One is for test suites, where connections to the database are made from one JVM context, immediately followed by another context. The other use is for applications where it is not easy to configure the environment to shutdown the database. Examples reported by users include web application servers, where the closing of the last connection conisides with the web app being shut down.

                In addition, when a connection to an in-process database creates a new database, or opens an existing database (i.e. it is the first connection made to the database by the application), all the user-defined database properties can be specified as URL properties. This can be used to specify properties to enforce more strict SQL adherence, or to change cache_scale or similar properties before the database files are created. However, for new databases, it is recommended to use the SET PROPERTY command for such settings.

                Properties Files

                HSQLDB relies on a set of properties files for different settings. Since 1.7.0 property naming has been streamlined and a number of new properties have been introduced.

                In all properties files, values are case-sensitive. All values apart from names of files or pages are required in lowercase (e.g. server.silent=FALSE will have no effect, but server.silent=false will work).

                The properties files and the settings stored in them are as follows:

                Table 4.3. Hsqldb Server Properties Files

                File NameLocationFunction
                server.propertiesthe directory where the command to run the Server class is issuedsettings for running HSQLDB as a database server communicating with the HSQL protocol
                webserver.propertiesthe directory where the command to run the WebServer class is issuedsettings for running HSQLDB as a database server communicating with the HTTP protocol
                <dbname>.propertiesthe directory where all the files for a database are locatedsettings for each particular database

                Properties files for running the servers are not created automatically. You should create your own files that contain server.property=value pairs for each property.

                The properties file for each database is generated by the database engine. This file can be edited after closing the database. In 1.8.0, most of these properties can be changed via SQL commands.

                Server and Web Server Properties

                In both server.properties and webserver.properties files, supported values and their defaults are as follows:

                Table 4.4. Property File Properties

                ValueDefaultDescription
                server.database.0testthe path and file name of the first database file to use
                server.dbname.0""lowercase server alias for the first database file
                server.urlid.0NONESqlTool urlid used by UNIX init script. (This property is not used if your are running Server/Webserver on a platform other than UNIX, or of you are not using our UNIX init script).
                server.silenttrueno extensive messages displayed on console
                server.tracefalseJDBC trace messages displayed on console

                In 1.8.0, each server can serve up to 10 different databases simultaneously. The server.database.0 property defines the filename / path whereas the server.dbname.0 defines the lowercase alias used by clients to connect to that database. The digit 0 is incremented for the second database and so on. Values for the server.database.{0-9} property can use the mem:, file: or res: prefixes and properties as discussed above under CONNECTIONS. For example, 

                    database.0=mem:temp;sql.enforce_strict_size=true;

                Values specific to server.properties are:

                Table 4.5. Server Property File Properties

                ValueDefaultDescription
                server.port9001 (normal) or 554 (if TLS encrypted)TCP/IP port used for talking to clients. All databases are served on the same port.
                server.no_system_exittrueno System.exit() call when the database is closed

                Values specific to webserver.properties are:

                Table 4.6. WebServer Property File Properties

                ValueDefaultDescription
                server.port80TCP/IP port used for talking to clients
                server.default_pageindex.htmlthe default web page for server
                server.root./the location of served pages
                .<extension>?multiple entries such as .html=text/html define the mime types of the static files served by the web server. See the source for WebServer.java for a list.

                All the above values can be specified on the command line to start the server by omitting the server. prefix.

                Starting a Server from your application

                If you want to start the server from within your application, as opposed to the command line or batch files, you should create an instance of Server or Web Server, then assign the properties in the form of a String and start the Server. An example of this can be found in the org.hsqldb.test.TestBase source.

                Note

                Upgrading: If you have existing custom properties files, change the values to the new naming convention. Note the use of digits at the end of server.database.n and server.dbname.n properties.

                Individual Database Properties

                Each database has its own <dbname>.properties file as part of a small group of files which also includes <dbname>.script and <dbname>.data. The properties files contain key/value pairs for some important settings.

                In version 1.8.0 a new SQL command allows most database properties to be modified as follows:

                    SET PROPERTY "property_name" property_value

                Properties that can be modified via SET PROPERTY are indicated in the table below. Other properties are indicated as PROPERTIES FILE ONLY and can be modified only by editing the .properties file after a shutdown and before a restart. Only the user-defined values listed below should ever be modified. Changing any other value could result in unexpected malfunction in database operations. Most of these values have been introduced for the new features since 1.7.0:

                Table 4.7. Database-specific Property File Properties

                ValueDefaultDescription
                readonlyfalsewhole database is read-only

                When true, the database cannot be modified in use. This setting can be changed to true if the database is to be opened from a CD. Prior to changing this setting, the database should be closed with the SHUTDOWN COMPACT command to ensure consistency and compactness of the data. (PROPERTIES FILE ONLY) but can be used as a connection property to open a normal database as readonly.

                hsqldb.files_readonlyfalsedatabase files will not be written to

                When true, data in MEMORY tables can be modified and new MEMORY tables can be added. However, these changes are not saved when the database is shutdown. CACHED and TEXT tables are always readonly when this setting is true. (PROPERTIES FILE ONLY)

                hsqldb.cache_file_scale1Set larger data file limits. Once set, the limit will go up to 8GB.

                This property can be set to 8 to increase the size limit of the .data file from 2GB to 8GB. To apply the change to an existing database, SHUTDOWN SCRIPT should be performed first, then the property=value line below should be added to the .properties file before reopening the database. 

                hsqldb.cache_file_scale=8

                The property can be set with the SQL command (as opposed to changing the value in the properties file) when the database has no CACHED tables (e.g. a new database). (SET PROPERTY)

                sql.enforce_sizefalsetrimming and padding string columns

                This property is no longer supported. Use sql.enforce_sctrict_size

                sql.enforce_strict_sizefalsesize enforcement and padding string columns

                Conforms to SQL standards for size and precision of data types. When true, all CHARACTER, VARCHAR, NUMERIC and DECIMAL values that are in a row affected by an INSERT INTO or UPDATE statement are checked against the size specified in the SQL table definition. An exception is thrown if the value is too long. Also all CHARACTER values that are shorter than the specified size are padded with spaces. TIMESTAMP(0) and TIMESTAMP(6) are also allowed in order to specify the subsecond resolution of the values. When false (default), stores the exact string that is inserted. (SET PROPERTY)

                sql.tx_no_multi_rewritefalsetransaction management

                In the default READ_UNCOMMITED mode, a transaction can write over rows inserted or updated by another uncommitted transaction. Setting this property to true will raise an exception when such a write is attempted (SET PROPERTY)

                hsqldb.cache_scale14memory cache exponent

                Indicates the maximum number of rows of cached tables that are held in memory, calculated as 3 *(2**value) (three multiplied by (two to the power value)). The default results in up to 3*16384 rows from all cached tables being held in memory at any time.

                The value can range between 8-18. (SET PROPERTY). If the value is set via SET PROPERTY then it becomes effective after the next database SHUTDOWN or CHECKPOINT. (SET PROPERTY)

                hsqldb.cache_size_scale10memory cache exponent

                Indicates the average size of each row in the memory cache used with cached tables, calculated as 2**value (two to the power value). This result value is multiplied by the maximum number of rows defined by hsqldb.cache_scale to form the maximum number of bytes for all the rows in memory cache. The default results in 1024 bytes per row. This default, combined with the default number of rows, results in approximately 50MB of the .data file to be stored in the memory cache.

                The value can range between 6-20. (SET PROPERTY). If the value is set via SET PROPERTY then it becomes effective after the next database SHUTDOWN or CHECKPOINT. (SET PROPERTY)

                hsqldb.log_size200size of log when checkpoint is performed

                The value is the size in megabytes that the .log file can reach before an automatic checkpoint occurs. A checkpoint and rewrites the .script file and clears the .log file. The value can be changed via the SET LOGSIZE nnn SQL command.

                runtime.gc_interval0forced garbage collection

                This setting forces garbage collection each time a set number of result set row or cache row objects are created. The default, "0" means no garbage collection is forced by the program.

                This should not be set when the database engine is acting as a server inside an exclusive JVM. The setting can be useful when the database is used in-process with the application with some Java Runtime Environments (JRE's). Some JRE's increase the size of the memory heap before doing any automatic garbage collection. This setting would prevent any unnecessary enlargement of the heap. Typical values for this setting would probably be between 10,000 to 100,000. (PROPERTIES FILE ONLY)

                hsqldb.nio_data_filetrueuse of nio access methods for the .data file

                When HSQLDB is compiled and run in Java 1.4 or higher, setting this property to false will avoid the use of nio access methods, resulting in somewhat reduced speed. If the data file is larger than 256MB when it is first opened, nio access methods are not used. Also, if the file gets larger than the amount of available computer memory that needs to be allocated for nio access, non-nio access methods are used.

                (SET PROPERTY). If used before defining any CACHED table, it applies to the current session, otherwise it comes to effect after a SHUTDOWN and restart or CHECKPOINT.

                hsqldb.default_table_typememorytype of table created with unqualified CREATE TABLE

                The CREATE TABLE command results in a MEMORY table by default. Setting the value "cached" for this property will result in a cached table by default. The qualified forms such as CREATE MEMORY TABLE or CREATE CACHED TABLE are not affected at all by this property. (SET PROPERTY)

                hsqldb.applog0application logging level

                The default level 0 indicates no logging. Level 1 results in events related to persistence to be logged, including any failures. The events are logged in a file ending with .app.log

                textdb.*0default properties for new text tables

                Properties that override the database engine defaults for newly created text tables. Settings in the text table SET <tablename> SOURCE <source string> command override both the engine defaults and the database properties defaults. Individual textdb.* properties are listed in the Text Tables chapter. (SET PROPERTY)

                When connecting to an in-process database creates a new database, or opens an existing database (i.e. it is the first connection made to the database by the application), all the user-defined database properties listed in this section can be specified as URL properties.

                Note

                Upgrading: From 1.7.0, the location of the database files can no longer be overridden by paths defined in the properties file. All files belonging to a database should reside in the same directory.

                The property sql.compare_in_locale=true is no longer supported. If the line exists in a .properties file, it will switch the database to the collation for the current default. See the SET DATABASE COLLATION[2] command.

                When HSQLDB is used in OpenOffice.org, some property values will have a different default. The properties and values are:

                hsqldb.default_table_type=cached hsqldb.cache_scale=13 hsqldb.log_size=10; hsqldb.nio_data_file=false sql.enforce_strict_size=true

                SQL Commands for Database Properties

                There are some database properties that are set with dedicated SQL commands beginning with SET.

                Table 4.8. SQL command properties

                SET WRITE_DELAY {{TRUE | FALSE} | <seconds> | <milliseconds> MILLIS

                The default is TRUE and indicates that the changes to the database that have been logged are synched to the file system once every 20 seconds. FALSE indicates there is no delay and at each commit a file synch operation is performed. Numeric values from 0 can also be specified for the synch delay.

                The purpose of this command is to control the amount of data loss in case of a total system crash. A delay of 1 second means at most the data written to disk during the last second before the crash is lost. All data written prior to this has been synced and should be recoverable

                This setting should be specified on the basis of the reliability of the hardware used for running the database engine, the type of disk system used, the possibility of power failure etc. Also the nature of the data stored should be considered.

                In general, when the system is very reliable, the setting can be left to the default. If it is not very reliable, or the data is critical a setting of 1 or 2 seconds would suffice. Only in the worst case scenario or with the most critical data should a setting of 0 or FALSE be specified as this will slow the engine down to the speed at which the file synch operation can be performed by the disk subsystem.

                Values down to 10 millisconds can be specified by adding MILLIS to the command, but in practice a delay of 100 milliseconds provides 99.99999% reliability with an average one system crash per 6 days.

                SET LOG_SIZE <numeric value>

                The engine writes out a log of all the changes to the database as they occur. This log is synched to the disk based on the WRITE_DELAY property above. The log is never reused unless there is an abnormal termination, i.e. the database process is terminated without SHUTDOWN, or it was terminated using SHUTDOWN IMMEDIATELY.

                The default maximum size of the .log file is 200 MB. When the maximum size is reached, a CHECKPOINT operation is performed. This operation will save the other database files in a consistent state and delete the old log. A value of 0 indicates no limit for the .log file.

                SET CHECKPOINT DEFRAG <numeric value>

                When rows in CACHED tables are updated or deleted, the spaces are mostly reused. However, in time, some unused spaces are left in the .data file, especially when large tables are dropped or their structure is modified.

                A CHECKPOINT operation does not normally reclaim the empty spaces, whereas CHECKPOINT DEFRAG always does.

                This property determines when a normal CHECKPOINT, whether initiated by an administrator or when the size of the log exceeds its limit.

                The numeric value is the number of megabytes of recorded empty spaces in the .data file that would force a DEFRAG operation. Low values result in more frequent DEFRAG operations. A value of 0 indicates no automatic DEFRAG is performed. The default is 200 megabytes of lost space.

                SET REFERENTIAL INTEGRITY {TRUE | FALSE}

                This is TRUE by default. If bulk data needs to be loaded into the database, this property can be set FALSE for the duration of bulk load operation. This allows loading data for related tables in any order. The property should be set TRUE after bulk load. If the loaded data is not guaranteed to conform to the referential integrity constraints, SQL queries should be run after loading to identify and modify any non-conforming rows.

                Brief Introduction

                The Database Manager tool is a simple GUI database query tool with a tree display of the tables. Both AWT and SWING versions of the tool are available and work almost identically. The AWT version class name is org.hsqldb.util.DatabaseManager; the SWING version, org.hsqldb.util.DatabaseManagerSwing.

                The AWT version of the database manager can be deployed as an applet in a browser. A demo HTML file with an embedded Database Manager is included in the /demo directory.

                When the Database Manager is started, a dialogue allows you to enter the JDBC driver, URL, user and password for the new connection. A drop-down box, Type, offers preset values for JDBC driver and URL for most popular database engines, including HSQLDB. Once you have selected an item from this drop-down box, you should edit the URL to specify the details of the database or any additional properties to pass. You should also enter the username and password before clicking on the OK button.

                The connection dialogue allows you to save the settings for the connection you are about to make. You can then access the connection in future sessions. To save a connection setting, enter a name in the Setting Name box before clicking on the OK button. Next time the connection dialogue is displayed, the drop-down box labeled Recent will include the name for all the saved connection settings. When you select a name, the individual settings are displayed in the appropriate boxes.

                The small Clr button next to the drop-down box allows you to clear all the saved settings. If you want to modify an existing setting, first select it from the drop-down box then modify any of the text boxes before making the connection. The modified values will be saved.

                Most menu items have context-sensitive tool tip help text which will appear if you hold the mouse cursor still over the desired menu item. (Assuming that you don't turn Tooltips off under the Help menu.

                The DatabaseManagers do work with HSQLDB servers serving TLS-encrypted JDBC data. See the TLS chapter and the RC File Authentication Setup section of this Guide.

                Tip

                If you are using DatabaseManagerSwing with Oracle, you will want to make sure that Show row counts and Show row counts are both off before connecting to the database. You may also want to turn off Auto tree-update, as described in the next section.

                Auto tree-update

                By default, the object tree in the left panel is refreshed when you execute DDL which may update those objects. If you are on a slow network or performance-challenged PC, use the view / Auto-refresh tree menu item to turn it off. You will then need to use the viewRefresh tree menu item every time that you want to refresh the tree.

                Note

                Auto-refresh tree does not automatically show all updates to database objects, it only refreshes when you submit DDL which may update database objects. (This behavior is a compromise between utility and performance).

                Automatic Connection

                You can use command-line switches to supply connection information. If you use these switch(es), then the connection dialog window will be skipped and a JDBC connection will be established immediately. Assuming that the hsqldb.jar (or an alternative jar) are in your CLASSPATH, this command will list the available command-line options. 

                    java org.hsqldb.util.DatabaseManagerSwing --help

                It's convenient to skip the connection dialog window if you always work with the same database account.

                Warning

                Use of the --password switch is not secure. Everything typed on command-lines is generally available to other users on the computer. The problem is compounded if you use a network connection to obtain your command line. The RC File section explains how you can set up automatic connections without supplying a password on the command line.

                RC File

                You can skip the connection dialog window securely by putting the connection information into an RC file and then using the --urlid switch to DatabaseManager or DatabaseManagerSwing. This strategy is great for adding launch menu items and/or launch icons to your desktop. You can set up one icon for each of the database accounts which you regularly use.

                The default location for the RC file is dbmanager.rc in your home directory. The RC File Authentication Setup section explains how to put the connection information into this text file. If you also run SqlTool, then you can share the RC file with SqlTool by using a sym-link (if your operating system supports sym links), or by using the --rcfile switch for either SqlTool or DatabaseManagerSwing.

                Warning

                Use your operating system facilities to prevent others from reading your RC file, since it contains passwords.

                To set up launch items/icons, first experiment on your command line to find exactly what command works. For example, 

                    java -cp /path/to/hsqldb.jar org.hsqldb.util.DatabaseManagerSwing --urlid mem
                Then, use your window manager to add an item that runs this command.

                Using the current DatabaseManagers with an older HSQLDB distribution.

                This procedure will allow users of a legacy version of HSQLDB to use all of the new features of the DatabaseManagers. You will also get the new version of the SqlTool! This procedure works for distros going back to 1.7.3.3 at least, probably much farther.

                These instructions assume that you are capable of running an Ant build. See the Building HSQLDB chapter.

                1. Download and extract a current HSQLDB distribution. If you don't want to use the source code, documentation, etc., you can use a temporary directory and remove it afterwards.

                2. Cd to the build directory under the root directory where you extracted the distribution to.

                3. Run ant hsqldbutil.

                4. If you're going to wipe out the build directory, copy hsqldbutil.jar to a safe location first.

                5. For now on, whenver you are going to run DatabaseManager*, make sure that you have this hsqldbutil.jar as the first item in your CLASSPATH.

                Here's a UNIX example where somebody wants to use the new DatabaseManagerSwing with their older HSQLDB database, as well as with Postgresql and a local application. 

                CLASSPATH=/path/to/hsqldbutil.jar:/home/bob/myapp/classes:/usr/local/lib/pg.jdbc3.jar
export CLASSPATH
java org.hsqldb.util.DatabaseManagerSwing --urlid urlid

                DatabaseManagerSwing as an Applet

                DatabaseManagerSwing is also an applet. You can use it in HTML, JSPs, etc. Be aware that in Applet mode, actions to load or save local files will be disabled, and attempts to access any server other than the HTML-serving-host will be fail.

                Since the Applet can not store or load locally saved preferences, the only way to have persistent preference settings is by using Applet parameters.

                Introduction

                The HSQLDB jar package is located in the /lib directory and contains several components and programs. Different commands are used to run each program.

                Components of the Hsqldb jar package

                • HSQLDB RDBMS

                • HSQLDB JDBC Driver

                • Database Manager (Swing and AWT versions)

                • Query Tool (AWT)

                • Sql Tool (command line)

                The HSQLDB RDBMS and JDBC Driver provide the core functionality. The rest are general-purpose database tools that can be used with any database engine that has a JDBC driver.

                Running Tools

                All tools can be run in the standard way for archived Java classes. In the following example the AWT version of the Database Manager, the hsqldb.jar is located in the directory ../lib relative to the current directory.

                    java -cp ../lib/hsqldb.jar org.hsqldb.util.DatabaseManager

                If hsqldb.jar is in the current directory, the command would change to:

                    java -cp hsqldb.jar org.hsqldb.util.DatabaseManager

                Main classes for the Hsqldb tools

                • org.hsqldb.util.DatabaseManager

                • org.hsqldb.util.DatabaseManagerSwing

                • org.hsqldb.util.Transfer

                • org.hsqldb.util.QueryTool

                • org.hsqldb.util.SqlTool

                Some tools, such as the Database Manager or SQL Tool, can use command line arguments or entirely rely on them. You can add the command line argument -? to get a list of available arguments for these tools. Database Manager features a graphical user interface and can be explored interactively.

                Running Hsqldb

                HSQLDB can be run in a number of different ways. In general these are divided into Server Modes and In-Process Mode (also called Standalone Mode). A different sub-program from the jar is used to run HSQLDB in each mode.

                Each HSQLDB database consists of between 2 to 5 files, all named the same but with different extensions, located in the same directory. For example, the database named "test" consists of the following files:

                • test.properties

                • test.script

                • test.log

                • test.data

                • test.backup

                The properties files contains general settings about the database. The script file contains the definition of tables and other database objects, plus the data for non-cached tables. The log file contains recent changes to the database. The data file contains the data for cached tables and the backup file is a zipped backup of the last known consistent state of the data file. All these files are essential and should never be deleted. If the database has no cached tables, the test.data and test.backup files will not be present. In addition to those files, HSQLDB database may link to any formatted text files, such as CSV lists, anywhere on the disk.

                While the "test" database is operational, a test.log file is used to write the changes made to data. This file is removed at a normal SHUTDOWN. Otherwise (with abnormal shutdown) this file is used at the next startup to redo the changes. A test.lck file is also used to record the fact that the database is open. This is deleted at a normal SHUTDOWN. In some circumstances, a test.data.old is created and deleted afterwards.

                Note

                When the engine closes the database at a shutdown, it creates temporary files with the extension .new which it then renames to those listed above.

                Server Modes

                Server modes provide the maximum accessibility. The database engine runs in a JVM and listens for connections from programs on the same computer or other computers on the network. Several different programs can connect to the server and retrieve or update information. Applications programs (clients) connect to the server using the HSQLDB JDBC driver. In most server modes, the server can serve up to 10 databases that are specified at the time of running the server.

                Server modes can use preset properties or command line arguments as detailed in the Advanced Topics chapter. There are three server modes, based on the protocol used for communications between the client and server.

                Hsqldb Server

                This is the preferred way of running a database server and the fastest one. A proprietary communications protocol is used for this mode. A command similar to those used for running tools and described above is used for running the server. The following example of the command for starting the server starts the server with one (default) database with files named "mydb.*".

                    java -cp ../lib/hsqldb.jar org.hsqldb.Server -database.0 file:mydb -dbname.0 xdb

                The command line argument -? can be used to get a list of available arguments.

                Hsqldb Web Server

                This mode is used when access to the computer hosting the database server is restricted to the HTTP protocol. The only reason for using the Web Server mode is restrictions imposed by firewalls on the client or server machines and it should not be used where there are no such restrictions. The HSQLDB Web Server is a special web server that allows JDBC clients to connect via HTTP. From 1.7.2 this mode also supports transactions.

                To run a web server, replace the main class for the server in the example command line above with the following:

                    org.hsqldb.WebServer

                The command line argument -? can be used to get a list of available arguments.

                Hsqldb Servlet

                This uses the same protocol as the Web Server. It is used when a separate servlet engine (or application server) such as Tomcat or Resin provides access to the database. The Servlet Mode cannot be started independently from the servlet engine. The Servlet class, in the HSQLDB jar, should be installed on the application server to provide the connection. The database is specified using an application server property. Refer to the source file org.hsqldb.Servlet.java to see the details.

                Both Web Server and Servlet modes can only be accessed using the JDBC driver at the client end. They do not provide a web front end to the database. The Servlet mode can serve only a single database.

                Please note that you do not normally use this mode if you are using the database engine in an application server.

                Connecting to a Database running as a Server

                Once an HSQLDB server is running, client programs can connect to it using the HSQLDB JDBC Driver contained in hsqldb.jar. Full information on how to connect to a server is provided in the Java Documentation for jdbcConnection (located in the /doc/src directory of HSQLDB distribution. A common example is connection to the default port (9001) used for the hsql protocol on the same machine:

                Example 1.1. Java code to connect to the local Server above

                    try {
        Class.forName("org.hsqldb.jdbcDriver" );
    } catch (Exception e) {
        System.out.println("ERROR: failed to load HSQLDB JDBC driver.");
        e.printStackTrace();
        return;
    }

    Connection c = DriverManager.getConnection("jdbc:hsqldb:hsql://localhost/xdb", "sa", "");

                In some circumstances, you may have to use the following line to get the driver.

                    Class.forName("org.hsqldb.jdbcDriver").newInstance();

                Note in the above connection URL, there is no mention of the database file, as this was specified when running the server. Instead, the value defined for dbname.0 is used. Also, see the Advanced Topics chapter for the connection URL when there is more than one database per server instance.

                Security Considerations

                When HSQLDB is run as a server, network access should be adequately protected. Source IP addresses may be restricted by use of TCP filtering or firewall programs, or standalone firewalls. If the traffic will cross an unprotected network (such as the Internet), the stream should be encrypted (for example by VPN, ssh tunneling, or TLS using the SSL enabled HSQLS and HTTPS variants of the server and web server modes). Only secure passwords should be used-- most importantly, the password for the default system user should be changed from the default empty string. If you are purposefully providing data to the public, then the wide-open public network connection should be used exclusively to access the public data via read-only accounts. (I.e., neither secure data nor privileged accounts should use this connection). These considerations also apply to HSQLDB servers run with the HTTP protocol.

                In-Process (Standalone) Mode

                This mode runs the database engine as part of your application program in the same Java Virtual Machine. For most applications this mode can be faster, as the data is not converted and sent over the network. The main drawback is that it is not possible by default to connect to the database from outside your application. As a result you cannot check the contents of the database with external tools such as Database Manager while your application is running. In 1.8.0, you can run a server instance in a thread from the same virtual machine as your application and provide external access to your in-process database.

                The recommended way of using the in-process mode in an application is to use an HSQLDB Server instance for the database while developing the application and then switch to In-Process mode for deployment.

                An In-Process Mode database is started from JDBC, with the database file path specified in the connection URL. For example, if the database name is testdb and its files are located in the same directory as where the command to run your application was issued, the following code is used for the connection:

                    Connection c = DriverManager.getConnection("jdbc:hsqldb:file:testdb", "sa", "");

                The database file path format can be specified using forward slashes in Windows hosts as well as Linux hosts. So relative paths or paths that refer to the same directory on the same drive can be identical. For example if your database path in Linux is /opt/db/testdb and you create an identical directory structure on the C: drive of a Windows host, you can use the same URL in both Windows and Linux:

                    Connection c = DriverManager.getConnection("jdbc:hsqldb:file:/opt/db/testdb", "sa", "");

                When using relative paths, these paths will be taken relative to the directory in which the shell command to start the Java Virtual Machine was executed. Refer to Javadoc for jdbcConnection for more details.

                Memory-Only Databases

                It is possible to run HSQLDB in a way that the database is not persistent and exists entirely in random access memory. As no information is written to disk, this mode should be used only for internal processing of application data, in applets or certain special applications. This mode is specified by the mem: protocol.

                    Connection c = DriverManager.getConnection("jdbc:hsqldb:mem:aname", "sa", "");

                You can also run a memory-only server instance by specifying the same URL in the server.properties. This usage is not common and is limited to special applications where the database server is used only for exchanging information between clients, or for non-persistent data.

                General

                Closing the Database

                All databases running in different modes can be closed with the SHUTDOWN command, issued as an SQL query. From version 1.7.2, in-process databases are no longer closed when the last connection to the database is explicitly closed via JDBC, a SHUTDOWN is required. In 1.8.0, a connection property, shutdown=true, can be specified on the first connection to the database (the connection that opens the database) to force a shutdown when the last connection closes.

                When SHUTDOWN is issued, all active transactions are rolled back. A special form of closing the database is via the SHUTDOWN COMPACT command. This command rewrites the .data file that contains the information stored in CACHED tables and compacts it to size. This command should be issued periodically, especially when lots of inserts, updates or deletes have been performed on the cached tables. Changes to the structure of the database, such as dropping or modifying populated CACHED tables or indexes also create large amounts of unused file space that can be reclaimed using this command.

                Using Multiple Databases in One JVM

                In the above examples each server serves only one database and only one in-memory database can be created. However, from version 1.7.2, HSQLDB can serve several databases in multiple server modes and allow simultaneous access to multiple in-process and memory-only databases. These capabilities are covered in the Advanced Topics chapter.

                Creating a New Database

                When a server instance is started, or when a connection is made to an in-process database, a new, empty database is created if no database exists at the given path.

                This feature has a side effect that can confuse new users. If a mistake is made in specifying the path for connecting to an existing database, a connection is nevertheless established to a new database. For troubleshooting purposes, you can specify a connection property ifexists=true to allow connection to an existing database only and avoid creating a new database. In this case, if the database does not exist, the getConnection() method will throw an exception.

                Using the Database Engine

                Once a connection is established to a database in any mode, JDBC methods are used to interact with the database. The Javadoc for jdbcConnection , jdbcDriver , jdbcDatabaseMetadata , jdbcResultSet , jdbcStatement , and jdbcPreparedStatement list all the supported JDBC methods together with information that is specific to HSQLDB. JDBC methods are broadly divided into: connection related methods, metadata methods and database access methods. The database access methods use SQL commands to perform actions on the database and return the results either as a Java primitive type or as an instance of the java.sql.ResultSet class.

                You can use Database Manager or other Java database access tools to explore your database and update it with SQL commands. These programs use JDBC internally to submit your commands to the database engine and to display the results in a human readable format.

                The SQL dialect used in HSQLDB is as close to the SQL92 and SQL200n standards as it has been possible to achieve so far in a small-footprint database engine. The full list of SQL commands is in the SQL Syntax chapter.

                Different Types of Tables

                HSQLDB supports TEMP tables and three types of persistent tables.

                TEMP tables are not written to disk and last only for the lifetime of the Connection object. The contents of each TEMP table is visible only from the Connection that was used to populate it; other concurrent connections to the database will have access to their own copies of the table. Since 1.8.0 the definition of TEMP tables conforms to the GLOBAL TEMPORARY type in the SQL standard. The definition of the table persists but each new connections sees its own copy of the table, which is empty at the beginning. When the connection commits, the contents of the table are cleared by default. If the table definition statements includes ON COMMIT PRESERVE ROWS, then the contents are kept when a commit takes place.

                The three types of persistent tables are MEMORY tables, CACHED tables and TEXT tables.

                Memory tables are the default type when the CREATE TABLE command is used. Their data is held entirely in memory but any change to their structure or contents is written to the <dbname>.script file. The script file is read the next time the database is opened, and the MEMORY tables are recreated with all their contents. So unlike TEMP table, the default, MEMORY tables are persistent.

                CACHED tables are created with the CREATE CACHED TABLE command. Only part of their data or indexes is held in memory, allowing large tables that would otherwise take up to several hundred megabytes of memory. Another advantage of cached tables is that the database engine takes less time to start up when a cached table is used for large amounts of data. The disadvantage of cached tables is a reduction in speed. Do not use cached tables if your data set is relatively small. In an application with some small tables and some large ones, it is better to use the default, MEMORY mode for the small tables.

                TEXT tables are supported since version 1.7.0 and use a CSV (Comma Separated Value) or other delimited text file as the source of their data. You can specify an existing CSV file, such as a dump from another database or program, as the source of a TEXT table. Alternatively, you can specify an empty file to be filled with data by the database engine. TEXT tables are efficient in memory usage as they cache only part of the text data and all of the indexes. The Text table data source can always be reassigned to a different file if necessary. Two commands are needed to set up a TEXT table as detailed in the Text Tables chapter.

                With memory-only databases (see above), both MEMORY table and CACHED table declarations are treated as declarations for non-persistent memory tables. TEXT table declarations are not allowed in this mode.

                Constraints and Indexes

                HSQLDB supports PRIMARY KEY, NOT NULL, UNIQUE, CHECK and FOREIGN KEY constraints. In addition, it supports UNIQUE or ordinary indexes. This support is fairly comprehensive and covers multi-column constraints and indexes, plus cascading updates and deletes for foreign keys.

                HSQLDB creates indexes internally to support PRIMARY KEY, UNIQUE and FOREIGN KEY constraints: a unique index is created for each PRIMARY KEY or UNIQUE constraint; an ordinary index is created for each FOREIGN KEY constraint. Because of this, you should not create duplicate user-defined indexes on the same column sets covered by these constraints. This would result in unnecessary memory and speed overheads. See the discussion in the SQL Issues chapter for more information.

                Indexes are crucial for adequate query speed. When queries joining multiple tables are used, there must be an index on each joined column of each table. When range or equality conditions are used e.g. SELECT ... WHERE acol >10 AND bcol = 0, an indexe is required on the acol column used in the condition. Indexes have no effect on ORDER BY clauses or some LIKE conditions.

                As a rule of thumb, HSQLDB is capable of internal processing of queries at over 100,000 rows per second. Any query that runs into several seconds should be checked and indexes should be added to the relevant columns of the tables if necessary.

                SQL Support

                The SQL syntax supported by HSQLDB is essentially that specified by the SQL Standard (92 and 200n). Not all the features of the Standard are supported and there are some proprietary extensions. In 1.8.0 the behaviour of the engine is far more compliant with the Standards than with older versions. The main changes are

                • correct treatment of NULL column values in joins, in UNIQUE constraints and in query conditions

                • correct processing of selects with JOIN and LEFT OUTER JOIN

                • correct processing of aggregate functions contained in expressions or containing expression arguments

                The supported commands are listed in the SQL Syntax chapter. For a well written basic guide to SQL with examples you can consult PostgreSQL: Introduction and Concepts by Bruce Momjian, which is available on the web. Most of the SQL coverage in the book applies also to HSQLDB. There are some differences in keywords supported by one and not the other engine (OUTER, OID's, etc.) or used differently (IDENTITY/SERIAL, TRIGGER, SEQUENCE, etc.).

                JDBC Support

                Since 1.7.2, support for JDBC2 has been significantly extended and some features of JDBC3 are also supported. The relevant classes are thoroughly documented. See the JavaDoc for org.hsqldb.jdbcXXXX classes.

                Purpose

                Many questions repeatedly asked in Forums and mailing lists are answered in this guide. If you want to use HSQLDB with your application, you should read this guide.

                SQL Standard Support

                HSQLDB 1.8.0 supports the dialect of SQL defined by SQL standards 92, 99 and 2003. This means where a feature of the standard is supported, e.g. left outer join, the syntax is that specified by the standard text. Many features of SQL92 and 99 up to Advanced Level are supported and there is support for most of SQL 2003 Foundation and several optional features of this standard. However, certain features of the Standards are not supported so no claim is made for full support of any level of the standards.

                The SQL Syntax chapter of this guide SQL Syntax lists all the keywords and syntax that is supported. When writing or converting existing SQL DDL (Data Definition Language) and DML (Data Manipulation Language) statements for HSQLDB, you should consult the supported syntax and modify the statements accordingly.

                Several words are reserved by the standard and cannot be used as table or column names. For example, the word POSITION is reserved as it is a function defined by the Standards with a similar role as String.indexOf() in Java. HSQLDB does not currently prevent you from using a reserved word if it does not support its use or can distinguish it. For example BEGIN is a reserved words that is not currently supported by HSQLDB and is allowed as a table or column name. You should avoid the use of such words as future versions of HSQLDB are likely to support the words and will reject your table definitions or queries. The full list of SQL reserved words is in the source of the org.hsqldb.Token class.

                HSQLDB also supports some keywords and expressions that are not part of the SQL standard as enhancements. Expressions such as SELECT TOP 5 FROM .., SELECT LIMIT 0 10 FROM ... or DROP TABLE mytable IF EXISTS are among such constructs.

                All keywords, can be used for database objects if they are double quoted.

                Constraints and Indexes

                Primary Key Constraints

                Before 1.7.0, a CONSTRAINT <name> PRIMARY KEY was translated internally to a unique index and, in addition, a hidden column was added to the table with an extra unique index. From 1.7.0 both single-column and multi-column PRIMARY KEY constraints are supported. They are supported by a unique index on the primary key column(s) specified and no extra hidden column is maintained for these indexes.

                Unique Constraints

                According to the SQL standards, a unique constraint on a single column means no two values are equal unless one of them is NULL. This means you can have one or more rows where the column value is NULL.

                A unique constraint on multiple columns (c1, c2, c3, ..) means that no two sets of values for the columns are equal unless at lease one of them is NULL. Each single column taken by itself can have repeat values. The following example satisfies a UNIQUE constraint on the two columns:

                Example 2.1. Column values which satisfy a 2-column UNIQUE constraint

                1,2
                2,1
                2,2
                NULL,1
                NULL,1
                1,NULL
                NULL,NULL
                NULL,NULL

                Since version 1.7.2 the behaviour of UNIQUE constraints and indexes with respect to NULL values has changed to conform to SQL standards. A row, in which the value for any of the UNIQUE constraint columns is NULL, can always be added to the table. So multiple rows can contain the same values for the UNIQUE columns if one of the values is NULL.

                Unique Indexes

                In 1.8.0, user defined UNIQUE indexes can still be declared but they are deprecated. You should use a UNIQUE constraint instead.

                CONSTRAINT <name> UNIQUE always creates internally a unique index on the columns, as with previous versions, so it has exactly the same effect as the deprecated UNIQUE index declaration.

                FOREIGN KEYS

                From version 1.7.0, HSQLDB features single and multiple column foreign keys. A foreign key can also be specified to reference a target table without naming the target column(s). In this case the primary key column(s) of the target table is used as the referenced column(s). Each pair of referencing and referenced columns in any foreign key should be of identical type. When a foreign key is declared, a unique constraint (or primary key) must exist on the referenced columns in the primary key table. A non-unique index is automatically created on the referencing columns. For example:

                    CREATE TABLE child(c1 INTEGER, c2 VARCHAR, FOREIGN KEY (c1, c2) REFERENCES parent(p1, p2));

                There must be a UNIQUE constraint on columns (p1,p2) in the table named "parent". A non-unique index is automatically created on columns (c1, c2) in the table named "child". Columns p1 and c1 must be of the same type (INTEGER). Columns p2 and c2 must be of the same type (VARCHAR).

                Indexes and Query Speed

                HSQLDB does not use indexes to improve sorting of query results. But indexes have a crucial role in improving query speed. If no index is used in a query on a single table, such as a DELETE query, then all the rows of the table must be examined. With an index on one of the columns that is in the WHERE clause, it is often possible to start directly from the first candidate row and reduce the number of rows that are examined.

                Indexes are even more important in joins between multiple tables. SELECT ... FROM t1 JOIN t2 ON t1.c1 = t2.c2 is performed by taking rows of t1 one by one and finding a matching row in t2. If there is no index index on t2.c2 then for each row of t1, all the rows of t2 must be checked. Whereas with an index, a matching row can be found in a fraction of the time. If the query also has a condition on t1, e.g., SELECT ... FROM t1 JOIN t2 ON t1.c1 = t2.c2 WHERE t1.c3 = 4 then an index on t1.c3 would eliminate the need for checking all the rows of t1 one by one, and will reduce query time to less than a millisecond per returned row. So if t1 and t2 each contain 10,000 rows, the query without indexes involves checking 100,000,000 row combinations. With an index on t2.c2, this is reduced to 10,000 row checks and index lookups. With the additional index on t2.c2, only about 4 rows are checked to get the first result row.

                Indexes are automatically created for primary key and unique columns. Otherwise you should define an index using the CREATE INDEX command.

                Note that in HSQLDB a unique index on multiple columns can be used internally as a non-unique index on the first column in the list. For example: CONSTRAINT name1 UNIQUE (c1, c2, c3); means there is the equivalent of CREATE INDEX name2 ON atable(c1);. So you do not need to specify an extra index if you require one on the first column of the list.

                In 1.8.0, a multi-column index will speed up queries that contain joins or values on ALL the columns. You need NOT declare additional individual indexes on those columns unless you use queries that search only on a subset of the columns. For example, rows of a table that has a PRIMARY KEY or UNIQUE constraint on three columns or simply an ordinary index on those columns can be found efficiently when values for all three columns are specified in the WHERE clause. For example, SELECT ... FROM t1 WHERE t1.c1 = 4 AND t1.c2 = 6 AND t1.c3 = 8 will use an index on t1(c1,c2,c3) if it exists.

                As a result of the improvements to multiple key indexes, the order of declared columns of the index or constraint has less affect on the speed of searches than before. If the column that contains more diverse values appears first, the searches will be slightly faster.

                A multi-column index will not speed up queries on the second or third column only. The first column must be specified in the JOIN .. ON or WHERE conditions.

                Query speed depends a lot on the order of the tables in the JOIN .. ON or FROM clauses. For example the second query below should be faster with large tables (provided there is an index on TB.COL3). The reason is that TB.COL3 can be evaluated very quickly if it applies to the first table (and there is an index on TB.COL3):

                    (TB is a very large table with only a few rows where TB.COL3 = 4)

    SELECT * FROM TA JOIN TB ON TA.COL1 = TB.COL2 AND TB.COL3 = 4;

    SELECT * FROM TB JOIN TA ON TA.COL1 = TB.COL2 AND TB.COL3 = 4;

                The general rule is to put first the table that has a narrowing condition on one of its columns.

                1.7.3 features automatic, on-the-fly indexes for views and subselects that are used in a query. An index is added to a view when it is joined to a table or another view.

                Where Condition or Join

                Using WHERE conditions to join tables is likely to reduce execution speed. For example the following query will generally be slow, even with indexes:

                    SELECT ... FROM TA, TB, TC WHERE TC.COL3 = TA.COL1 AND TC.COL3=TB.COL2 AND TC.COL4 = 1

                The query implies TA.COL1 = TB.COL2 but does not explicitly set this condition. If TA and TB each contain 100 rows, 10000 combinations will be joined with TC to apply the column conditions, even though there may be indexes on the joined columns. With the JOIN keyword, the TA.COL1 = TB.COL2 condition has to be explicit and will narrow down the combination of TA and TB rows before they are joined with TC, resulting in much faster execution with larger tables:

                    SELECT ... FROM TA JOIN TB ON TA.COL1 = TB.COL2 JOIN TC ON TB.COL2 = TC.COL3 WHERE TC.COL4 = 1

                The query can be speeded up a lot more if the order of tables in joins are changed, so that TC.COL1 = 1 is applied first and a smaller set of rows are joined together:

                    SELECT ... FROM TC JOIN TB ON TC.COL3 = TB.COL2 JOIN TA ON TC.COL3 = TA.COL1 WHERE TC.COL4 = 1

                In the above example the engine automatically applies TC.COL4 = 1 to TC and joins only the set of rows that satisfy this condition with other tables. Indexes on TC.COL4, TB.COL2 and TA.COL1 will be used if present and will speed up the query.

                Subqueries and Joins

                Using joins and setting up the order of tables for maximum performance applies to all areas. For example, the second query below should generally be much faster if there are indexes on TA.COL1 and TB.COL3:

                Example 2.2. Query comparison

                    SELECT ... FROM TA WHERE TA.COL1 = (SELECT MAX(TB.COL2) FROM TB WHERE TB.COL3 = 4)

    SELECT ... FROM (SELECT MAX(TB.COL2) C1 FROM TB WHERE TB.COL3 = 4) T2 JOIN TA ON TA.COL1 = T2.C1

                The second query turns MAX(TB.COL2) into a single row table then joins it with TA. With an index on TA.COL1, this will be very fast. The first query will test each row in TA and evaluate MAX(TB.COL2) again and again.

                Types and Arithmetic Operations

                Table columns of all types supported by HSQLDB can be indexed and can feature in comparisons. Types can be explicitly converted using the CONVERT() library function, but in most cases they are converted automatically. It is recommended not to use indexes on LONGVARBINARY, LONGVARCHAR and OTHER columns, as these indexes will probably not be allowed in future versions.

                Previous versions of HSQLDB featured poor handling of arithmetic operations. For example, it was not possible to insert 10/2.5 into any DOUBLE or DECIMAL column. Since 1.7.0, full operations are possible with the following rules:

                TINYINT, SMALLINT, INTEGER, BIGINT, NUMERIC and DECIMAL (without a decimal point) are supported integral types and map to byte, short, int, long and BigDecimal in Java. The SQL type dictates the maximum and minimum values that can be held in a field of each type. For example the value range for TINYINT is -128 to +127, although the actual Java type used for handling TINYINT is java.lang.Integer.

                REAL, FLOAT, DOUBLE are all mapped to double in Java.

                DECIMAL and NUMERIC are mapped to java.math.BigDecimal and can have very large numbers of digits.

                Integral Types

                TINYINT, SMALLINT, INTEGER, BIGINT, NUMERIC and DECIMAL (without a decimal point) are fully interchangeable internally, and no data narrowing takes place. Depending on the types of the operands, the result of the operations is returned in a JDBC ResultSet in any of related Java types: Integer, Long or BigDecimal. The ResultSet.getXXXX() methods can be used to retrieve the values so long as the returned value can be represented by the resulting type. This type is deterministically based on the query, not on the actual rows returned. The type does not change when the same query that returned one row, returns many rows as a result of adding more data to the tables.

                If the SELECT statement refers to a simple column or function, then the return type is the type corresponding to the column or the return type of the function. For example:

                    CREATE TABLE t(a INTEGER, b BIGINT); SELECT MAX(a), MAX(b) FROM t;

                would return a result set where the type of the first column is java.lang.Integer and the second column is java.lang.Long. However,

                    SELECT MAX(a) + 1, MAX(b) + 1 FROM t;

                would return java.lang.Long and BigDecimal values, generated as a result of uniform type promotion for all the return values.

                There is no built-in limit on the size of intermediate integral values in expressions. As a result, you should check for the type of the ResultSet column and choose an appropriate getXXXX() method to retrieve it. Alternatively, you can use the getObject() method, then cast the result to java.lang.Number and use the intValue() or longValue() methods on the result.

                When the result of an expression is stored in a column of a database table, it has to fit in the target column, otherwise an error is returned. For example when 1234567890123456789012 / 12345687901234567890 is evaluated, the result can be stored in any integral type column, even a TINYINT column, as it is a small value.

                Other Numeric Types

                In SQL statements, numbers with a decimal point are treated as DECIMAL unless they are written with an exponent. Thus 0.2 is considered a DECIMAL value but 0.2E0 is considered a DOUBLE value.

                When PreparedStatement.setDouble() or setFloat() is used, the value is treated as a DOUBLE automatically.

                When a REAL, FLOAT or DOUBLE (all synonymous) is part of an expression, the type of the result is DOUBLE.

                Otherwise, when no DOUBLE value exists, if a DECIMAL or NUMERIC value is part an expression, the type of the result is DECIMAL. The result can be retrieved from a ResultSet in the required type so long as it can be represented. This means DECIMAL values can be converted to DOUBLE unless they are beyond the Double.MIN_VALUE - Double.MAX_VALUE range. Similar to integral values, when the result of an expression is stored in a table column, it has to fit in the target column, otherwise an error is returned.

                The distinction between DOUBLE and DECIMAL is important when a division takes place. When the terms are DECIMAL, the result is a value with a scale (number of digits to the right of the decimal point) equal to the larger of the scales of the two terms. With a DOUBLE term, the scale will reflect the actual result of the operation. For example, 10.0/8.0 (DECIMAL) equals 1.2 but 10.0E0/8.0E0 (DOUBLE) equals 1.25. Without division operations, DECIMAL values represent exact arithmetic; the resulting scale is the sum of the scales of the two terms when multiplication is performed.

                REAL, FLOAT and DOUBLE values are all stored in the database as java.lang.Double objects. Special values such as NaN and +-Infinity are also stored and supported. These values can be submitted to the database via JDBC PreparedStatement methods and are returned in ResultSet objects.

                Bit and Boolean Types

                Since 1.7.2, BIT is simply an alias for BOOLEAN. The primary representation of BOOLEAN column is 'true' or 'false' either as the boolean type or as strings when used from JDBC. This type of column can also be initialised using values of any numeric type. In this case 0 is translated to false and any other value such as 1 is translated to true.

                Since 1.7.3 the BOOLEAN type conforms to the SQL standards and supports the UNDEFINED state in addition to TRUE or FALSE. NULL values are treated as undefined. This improvement affects queries that contain NOT IN. See the test text file, TestSelfNot.txt, for examples of the queries.

                Storage and Handling of Java Objects

                Since version 1.7.2 this support has improved and any serializable JAVA Object can be inserted directly into a column of type OTHER using any variation of PreparedStatement.setObject() methods.

                For comparison purposes and in indexes, any two Java Objects are considered equal unless one of them is NULL. You cannot search for a specific object or perform a join on a column of type OTHER.

                Please note that HSQLDB is not an object-relational database. Java Objects can simply be stored internally and no operations should be performed on them other than assignment between columns of type OTHER or tests for NULL. Tests such as WHERE object1 = object2, or WHERE object1 = ? do not mean what you might expect, as any non-null object would satisfy such a tests. But WHERE object1 IS NOT NULL is perfectly acceptable.

                The engine does not return errors when normal column values are assigned to Java Object columns (for example assigning an INTEGER or STRING to such a column with an SQL statement such as UPDATE mytable SET objectcol = intcol WHERE ...) but this is highly likely to be disallowed in future. So please use columns of type OTHER only to store your objects and nothing else.

                Type Size, Precision and Scale

                Prior to 1.7.2, all table column type definitions with a column size, precision or scale qualifier were accepted and ignored.

                In 1.8.0, such qualifiers must conform to the SQL standards. For example INTEGER(8) is no longer acceptable. The qualifiers are still ignored unless you set a database property. SET PROPERTY "sql.enforce_strict_size" TRUE will enforce sizes for CHARACTER or VARCHAR columns and pad any strings when inserting or updating a CHARACTER column. The precision and scale qualifiers are also enforced for DECIMAL and NUMERIC types. TIMESTAMP can be used with a precision of 0 or 6 only.

                Casting a value to a qualified CHARACTER type will result in truncation or padding as you would expect. So a test such as CAST (mycol AS VARCHAR(2)) = 'xy' will find the values beginning with 'xy'. This is the equivalent of SUBSTRING(mycol FROM 1 FOR 2) = 'xy'.

                Sequences and Identity

                The SEQUENCE keyword was introduced in 1.7.2 with a subset of the SQL 200n standard syntax. Corresponding SQL 200n syntax for IDENTITY columns has also been introduced.

                Identity Auto-Increment Columns

                Each table can contain one auto-increment column, known as the IDENTITY column. An IDENTITY column is always treated as the primary key for the table (as a result, multi-column primary keys are not possible with an IDENTITY column present). Support has been added for CREATE TABLE <tablename>(<colname> IDENTITY, ...) as a shortcut.

                Since 1.7.2, the SQL standard syntax is used by default, which allows the initial value to be specified. The supported form is(<colname> INTEGER GENERATED BY DEFAULT AS IDENTITY(START WITH n, [INCREMENT BY m])PRIMARY KEY, ...). Support has also been added for BIGINT identity columns. As a result, an IDENTITY column is simply an INTEGER or BIGINT column with its default value generated by a sequence generator.

                When you add a new row to such a table using an INSERT INTO <tablename> ...; statement, you can use the NULL value for the IDENTITY column, which results in an auto-generated value for the column. The IDENTITY() function returns the last value inserted into any IDENTITY column by this connection. Use CALL IDENTITY(); as an SQL statement to retrieve this value. If you want to use the value for a field in a child table, you can use INSERT INTO <childtable> VALUES (...,IDENTITY(),...);. Both types of call to IDENTITY() must be made before any additional update or insert statements are issued on the database.

                The next IDENTITY value to be used can be set with the 

                ALTER TABLE ALTER COLUMN <column name> RESTART WITH <new value>;

                Sequences

                The SQL 200n syntax and usage is different from what is supported by many existing database engines. Sequences are created with the CREATE SEQUENCE command and their current value can be modified at any time with ALTER SEQUENCE. The next value for a sequence is retrieved with the NEXT VALUE FOR <name> expression. This expression can be used for inserting and updating table rows. You can also use it in select statements. For example, if you want to number the returned rows of a SELECT in sequential order, you can use:

                Example 2.3. Numbering returned rows of a SELECT in sequential order

                    SELECT NEXT VALUE FOR mysequence, col1, col2 FROM mytable WHERE ...

                Please note that the semantics of sequences is not exactly the same as defined by SQL 200n. For example if you use the same sequence twice in the same row insert query, you will get two different values, not the same value as required by the standard.

                You can query the SYSTEM_SEQUENCES table for the next value that will be returned from any of the defined sequences. The SEQUENCE_NAME column contains the name and the NEXT_VALUE column contains the next value to be returned.

                Issues with Transactions

                HSQLDB supports transactions at the READ_UNCOMMITTED level, also known as level 0 transaction isolation. This means that during the lifetime of a transaction, other connections to the database can see the changes made to the data. Transaction support works well in general. Reported bugs concerning transactions being committed if the database is abruptly closed have been fixed. However, the following issues may be encountered only with multiple connections to a database using transactions:

                If two transactions modify the same row, no exception is raised when both transactions are committed. This can be avoided by designing your database in such a way that application data consistency does not depend on exclusive modification of data by one transaction. You can set a database property to cause an exception when this happens.

                SET PROPERTY "sql.tx_no_multi_rewrite" TRUE
                When an ALTER TABLE .. INSERT COLUMN or DROP COLUMN command results in changes to the table structure, the current session is committed. If an uncommitted transaction started by another connections has changed the data in the affected table, it may not be possible to roll it back after the ALTER TABLE command. This may also apply to ADD INDEX or ADD CONSTRAINT commands. It is recommended to use these ALTER commands only when it is known that other connections are not using transactions.

                After a CHECKPOINT command is issued, uncommitted transactions can be continued, committed, or rolled back. However, if the database is not subsequently closed properly with the SHUTDOWN command, any such transaction that still remains uncommitted at the time of shutdown, is part committed (to the state at CHECKPOINT) at the next startup. It is recommended to use the CHECKPOINT command either when no uncommitted transactions is in progress, or it is known that any such transaction is not likely to last for such a long time that an abnormal shutdown might affect its data.

                New Features and Changes

                In recent versions leading to 1.8.0 many enhancements were made for better SQL support. These are listed in the SQL Syntax chapter, in ../changelog_1_8_0.txt and ../changelog_1_7_2.txt. Functions and expressions such as POSITION(), SUBSTRING(), NULLIF(), COALESCE(), CASE ... WHEN .. ELSE, ANY, ALL etc. are among them. Other enhancements may not be very obvious in the documentation but can result in changes of behaviour from previous versions. Most significant among these are handling of NULL values in joins (null columns are no longer joined) and OUTER joins (the results are now correct). You should test your applications with the new version to ensure they do not rely on past incorrect behaviour of the engine. The engine will continue to evolve in future versions towards full SQL standard support, so it is best not to rely on any non-standard feature of the current version.

                Purpose

                This chapter explains how to quickly install, run, and use HSQLDB on UNIX.

                HSQLDB has lots of great optional features. I intend to cover very few of them. I do intend to cover what I think is the most common UNIX setup: To run a multi-user database with permament data persistence. (By the latter I mean that data is stored to disk so that the data will persist across database shutdowns and startups). I also cover how to run HSQLDB as a system daemon.

                Installation

                Go to http://sourceforge.net/projects/hsqldb and click on the "files" link. You want the current version. This will be the highest numbered version under the plain black "hsqldb" heading. See if there's a distribution for the current HSQLDB version in the format that you want.

                If you want an rpm, you should still find out the current version of HSQLDB as described in the previous paragraph. Then click "hsqldb" in the "free section" of http://www.jpackage.org/ and see if they have the current HSQLDB version built yet. Hopefully, the JPackage folk will document what JVM versions their rpm will support (currently they document this neither on their site nor within the package itself). (I really can't document how to download from a site that is totally beyond my control).

                Note

                It could very well happen that some of the file formats which I discuss below are not in fact offered. If so, then we have not gotten around to building them.

                Binary installation depends on the package format that you downloaded.

                Installing from a .pkg.Z file

                This package is only for use by a Solaris super-user. It's a System V package. Download then uncompress the package with uncompress or gunzip 

                    uncompress filename.pkg.Z
                You can read about the package by running 
                    pkginfo -l -d filename.pkg
                Run pkgadd as root to install. 

                    pkgadd -d filename.pkg
                Installing from a .rpm file

                This is a Linux rpm package. After you download the rpm, you can read about it by running 

                    rpm -qip /path/to/file.rpm

                Rpms can be installed or upgraded by running 

                    rpm -Uvh /path/to/file.rpm
                as root. Suse users may want to keep Yast aware of installed packages by running rpm through Yast: yast2 -i /path/to/file.rpm.

                Installing from a .zip file

                Extract the zip file to the parent directory of the new HSQLDB home. You don't need to create the HSQLDB_HOME directory because the extraction will create it for you with the right name) 

                    cd parent/of/new/hsqldb/home
    unzip /path/to/file.zip

                All the files in the zip archive will be extracted to underneath a new hsqldb directory.

                Take a look at the files you installed. (Under hsqldb for zip file installations. Otherwise, use the utilities for your packaging system). The most important file of the hsqldb system is hsqldb.jar, which resides in the directory lib.

                Important

                For the purposes of this chapter, I define HSQLDB_HOME to be the parent directory of the lib directory that contains hsqldb.jar. E.g., if your path to hsqldb.jar is /a/b/hsqldb/lib/hsqldb.jar, then your HSQLDB_HOME is /a/b/hsqldb.

                If the description of your distribution says that the hsqldb.jar file will work for your Java version, then you are finished with installation. Otherwise you need to build a new hsqldb.jar file.

                If you followed the instructions above and you still don't know what Java version your hsqldb.jar supports, then read HSQLDB_HOME/readme.txt and HSQLDB_HOME/index.html. If that still doesn't help, then you can just try your hsqldb.jar and see if it works, or build your own.

                To use the supplied hsqldb.jar, just skip to the next section of this document. Otherwise build a new hsqldb.jar.

                Procedure 3.1. Building hsqldb.jar

                1. If you don't already have Ant, download the latest stable binary version from http://ant.apache.org. cd to where you want Ant to live, and extract from the archive with 

                      unzip /path/to/file.zip
                  or
                      tar -xzf /path/to/file.tar.gz
                  or
                      bunzip2 -c /path/to/file.tar.bz2 | tar -xzf -
                  Everything will be installed into a new subdirectory named apache-ant- + version. You can rename the directory after the extraction if you wish.

                2. Set the environmental variable JAVA_HOME to the base directory of your Java JRE or SDK, like 

                      export JAVA_HOME; JAVA_HOME=/usr/java/j2sdk1.4.0
                  The location is entirely dependent upon your variety of UNIX. Sun's rpm distributions of Java normally install to /usr/java/something. Sun's System V package distributions of Java (including those that come with Solaris) normally install to /usr/something, with a sym-link from /usr/java to the default version (so for Solaris you will usually set JAVA_HOME to /usr/java).

                3. Remove the existing file HSQLDB_HOME/lib/hsqldb.jar.

                4. cd to HSQLDB_HOME/build. Make sure that the bin directory under your Ant home is in your search path. Run the following command. 

                      ant hsqldb
                  This will build a new HSQLDB_HOME/lib/hsqldb.jar.

                See the Building HSQLDB appendix if you want to build anything other than hsqldb.jar with all default settings.

                Setting up a Hsqldb Persistent Database Instance and a Hsqldb Server

                If you installed from an OS-specific package, you may already have a database instance and server pre-configured. See if your package includes a file named server.properties (make use of your packaging utilities). If you do, then I suggest that you still read this section while you poke around, in order to understand your setup.

                1. Select a UNIX user to run the database as. If this database is for the use of multiple users, or is a production system (or to emulate a production system), you should dedicate a UNIX user for this purpose. In my examples, I use the user name hsqldb. In this chapter, I refer to this user as the HSQLDB_OWNER, since that user will own the database instance files and processes.

                  If the account doesn't exist, then create it. On all system-5 UNIXes and most hybrids (including Linux), you can run (as root) something like 

                      useradd -c 'HSQLDB Database Owner' -s /bin/bash -m hsqldb
                  (BSD-variant users can use a similar pw useradd hsqldb... command).

                2. Become the HSQLDB_OWNER. Copy the sample file HSQLDB_HOME/src/org/hsqldb/sample/sample-server.properties to the HSQLDB_OWNER's home directory and rename it to server.properties. 

                  # Hsqldb Server cfg file.
# See the Advanced Topics chapter of the Hsqldb User Guide.

server.database.0   file:db0/db0
# I suggest that, for every file: database you define, you add the
# connection property "ifexists=true" after the database instance
# is created (which happens simply by starting the Server one time).
# Just append ";ifexists=true" to the file: URL, like so:
# server.database.0   file:db0/db0;ifexists=true

                  Since the value of the first database (server.database.0) begins with file:, the database instance will be persisted to a set of files in the specified directory with names beginning with the specified name. Set the path to whatever you want (relative paths will be relative to the directory containing the properties file). You can read about how to specify other database instances of various types, and how to make settings for the listen port and many other things, in the Advanced Topics chapter.

                3. Set and export the environmental variable CLASSPATH to the value of HSQLDB_HOME (as described above) plus "/lib/hsqldb.jar", like 

                      export CLASSPATH; CLASSPATH=/path/to/hsqldb/lib/hsqldb.jar
                  In HSQLDB_OWNER's home directory, run

                      nohup java org.hsqldb.Server &

                  This will start the Server process in the background, and will create your new database instance "db0". Continue on when you see the message containing HSQLDB server... is online. nohup just makes sure that the command will not quit when you exit the current shell (omit it if that's what you want to do).

                Accessing your Database

                Copy the file HSQLDB_HOME/src/org/hsqldb/sample/sqltool.rc to the HSQLDB_OWNER's home directory. Use chmod to make the file readable and writable only to HSQLDB_OWNER. 

                # $Id: sqltool.rc,v 1.22 2007/08/09 03:22:21 unsaved Exp $

# This is a sample RC configuration file used by SqlTool, DatabaseManager,

# This will access the first urlid definition below in order to use a

# (which you can get from the directory $ORACLE_HOME/jdbc/lib of any
# Oracle installation compatible with your server).
# Since you need to add to the classpath, you can't invoke SqlTool with
# the jar switch, like "java -jar .../hsqldb.jar..." or 
# "java -jar .../hsqlsqltool.jar...".
# Put both the HSQLDB jar and classes12.zip in your classpath (and export!)

# not to implement the SQL standard statement "commit"!!
# Note that SqlTool can not shut down an embedded Derby database properly,
# since that requires an additional SQL connection just for that purpose.
# However, I've never lost data by not shutting it down properly.
# Other than not supporting this quirk of Derby, SqlTool is miles ahead of ij.

                We will be using the "localhost-sa" sample urlid definition from the config file. The JDBC URL for this urlid is jdbc:hsqldb:hsql://localhost. That is the URL for the default database instance of a HSQLDB Server running on the default port of the local host. You can read about URLs to connect to other instances and other servers in the Advanced Topics chapter.

                Run SqlTool. 

                    java -jar path/to/hsqldb.jar localhost-sa
                If you get a prompt, then all is well. If security is of any concern to you at all, then you should change the privileged password in the database. Use the command SET PASSWORD command to change SA's password. 
                    set password "newpassword";

                When you're finished playing, exit with the command \q.

                If you changed the SA password, then you need to fix the password in the sqltool.rc file accordingly.

                You can, of course, also access the database with any JDBC client program. See the First JDBC Client Example appendix. You will need to modify your classpath to include hsqldb.jar as well as your client class(es). You can also use the other HSQLDB client programs, such as org.hsqldb.util.DatabasManagerSwing, a graphical client with a similar purpose to SqlTool.

                You can use any normal UNIX account to run the JDBC clients, including SqlTool, as long as the account has read access to the hsqldb.jar file and to an sqltool.rc file. See the SqlTool chapter about where to put sqltool.rc, how to execute sql files, and other SqlTool features.

                Create additional Accounts

                Connect to the database as SA (or any other Administrative user) and run CREATE USER to create new accounts for your database instance. HSQLDB accounts are database-instance-specific, not Server-specific.

                For the current version of HSQLDB, only users with Role of DBA may create or own database objects. DBA members have privileges to do anything. Non-DBAs may be granted some privileges, but may never create or own database objects. (Before long, non-DBAs will be able to create objects if they have permission to do so in the target schema). When you first create a hsqldb database, it has only one database user-- SA, a DBA account, with an empty string password. You should set a password (as described above). You can create as many additional users as you wish. To make a user a DBA, you can use the "ADMIN" option to the CREATE USER command, or GRANT the DBA Role to the account after creating it.

                If you create a user without the ADMIN tag (and without granting the DBA role to them) this user will be able to read the data dictionary tables, but will be able unable to create or own his own objects. He will have only the rights which the pseudo-user PUBLIC has. To give him more permissions, even rights to read objects, you can GRANT permissions for specific objects, grant Roles (which encompass a set of permissions), or grant the DBA Role itself.

                Since only people with a database account may do anything at all with the database, it is often useful to permit other database users to view the data in your tables. To optimize performance, reduce contention, and minimize administration, it is often best to grant SELECT to PUBLIC on any object that needs to be accessed by multiple database users (with the significant exception of any data which you want to keep secret).

                Shutdown

                Do a clean database shutdown when you are finished with the database instance. You need to connect up as SA or some other Admin user, of course. With SqlTool, you can run 

                    java -jar path/to/hsqldb.jar --sql shutdown localhost-sa
                You don't have to worry about stopping the Server because it shuts down automatically when all served database instances are shut down.

                Running Hsqldb as a System Daemon

                You can, of course, run HSQLDB through inittab on System V UNIXes, but usually an init script is more convenient and manageable. This section explains how to set up and use our UNIX init script. Our init script is only for use by root. (That is not to say that the Server will run as root-- it usually should not).

                The main purpose of the init script is to start up a Server with the database instances specified in your server.properties file; and to shut down all of those instances plus additional urlids which you may (optionally) list in your init script config file. These urlids must all have entries in a sqltool.rc file. If, due to firewall issues, you want to run a WebServer instead of a Server, then make sure you have a healthy WebServer with a webserver.properties set up, adjust your URLs in sqltool.rc, and set TARGET_CLASS in the config file. (By following the commented examples in the config file, you can start up any number of Server and/or WebServer listeners with or without TLS ecryption).

                After you have the init script set up, root can use it anytime to start or stop HSQLDB. (I.e., not just at system bootup or shutdown).

                Portability of hsqldb init script

                The primary design criterion of the init script is portability. It does not print pretty color startup/shutdown messages as is common in late-model Linuxes and HPUX; and it does not keep subsystem state files or use the startup/shutdown functions supplied by many UNIXes, because these features are all non-portable.

                Offsetting these limitations, this one script does it's intended job great on the UNIX varieties I have tested, and can easily be modified to accommodate other UNIXes. While you don't have tight integration with OS-specific daemon administration guis, etc., you do have a well tested and well behaved script that gives good, utilitarian feedback.

                Init script Setup Procedure

                The strategy taken here is to get the init script to run your single Server or WebServer first (as specified by TARGET_CLASS). After that's working, you can customize the JVM that is run by running additional Servers in it, running your own application in it (embedding), or even overriding HSQLDB behavior with your own overriding classes.

                1. Copy the init script hsqldb from HSQLDB_HOME/bin into the directory where init scripts live on your variety of UNIX. The most common locations are /etc/init.d or /etc/rc.d/init.d on System V style UNIXes, /usr/local/etc/rc.d on BSD style UNIXes, and /Library/StartupItems/hsqldb on OS X (you'll need to create the directory for the last).

                2. Look at the comment towards the top of the init script which lists recommended locations for the configuration file for various UNIX platforms. Copy the sample config file HSQLDB_HOME/src/org/hsqldb/sample/sample-hsqldb.cfg to one of the listed locations (your choice). Edit the config file according to the instructions in it.

JAVA_EXECUTABLE=/usr/bin/java

# Unless you copied a hsqldb.jar file from another system, this typically
# resides at $HSQLDB_HOME/lib/hsqldb.jar, where $HSQLDB_HOME is your HSQLDB
# software base directory.
HSQLDB_JAR_PATH=/opt/hsqldb/lib/hsqldb.jar

# Where the file "server.properties" resides.
SERVER_HOME=/opt/hsqldb/data

# What UNIX user the server will run as.
# (The shutdown client is always run as root or the invoker of the init script).
# Runs as root by default, but you should take the time to set database file
# ownerships to another user and set that user name here.
HSQLDB_OWNER=hsqldb

# The HSQLDB jar file specified in HSQLDB_JAR_PATH above will automatically
# be in the class path.  This arg specifies additional classpath elements.
# To embed your own application, add your jar file(s) or class base
# directories here, and add your main class to the INVOC_ADDL_ARGS setting
# below.
#SERVER_ADDL_CLASSPATH=/usr/local/dist/currencybank.jar

# We require all Server/WebServer instances to be accessible within 
# $MAX_START_SECS from when the Server/WebServer is started.
# Defaults to 60.
# Raise this is you are running lots of DB instances or have a slow server.
#MAX_START_SECS=200

# Time to allow for JVM to die after all HSQLDB instances stopped.
# Defaults to 1.
#MAX_TERMINATE_SECS=0

# These are "urlid" values from a SqlTool authentication file
# ** IN ADDITION TO THOSE IN YOUR server.properties OR webserver.properties **
# file.  All server.urlid.X values from your properties file will automatically
# be started/stopped/tested.  $SHUTDOWN_URLIDS is for additional urlids which
# will stopped.  (Therefore, most users will not set this at all).
# Separate multiple values with white space.  NO OTHER SPECIAL CHARACTERS!
# Make sure to quote the entire value if it contains white space separator(s).
# Defaults to none (i.e., only urlids set in properties file will be stopped).
#SHUTDOWN_URLIDS='sa mygms'

# SqlTool authentication file used only for shutdown.
# The default value will be sqltool.rc in root's home directory, since it is 
# root who runs the init script.
# (See the SqlTool chapter of the HSQLDB User Guide if you don't understand 
# this).
#AUTH_FILE=/home/blaine/sqltool.rc

# Set this to either 'WebServer' or 'Server'.  Defaults to Server.
# The JVM that is started can invoke many classes (see the following item
# about that), but this is the Server that is used (1) to check status,
# (2) to shut down the JVM, (3) to get urlids for #1 from the 
# server's server/webserver.properties file.
#TARGET_CLASS=WebServer
# Note that you don't specify the org.hsqldb package, since you have no 
# choice in the matter (you can only run org.hsqldb.Server or 
# org.hsqldb.WebServer).  If you specify additional classes with
# INVOC_ADDL_ARGS (described next), you do need to specify the
# full class name with package name.

# This is where you specify exactly what your HSQLDB JVM will run.
# The class org.hsqldb.util.MainInvoker will run the TARGET_CLASS
# specified above with any arguments supplied here + any other classes
# and arguments.  Every additional class (in addition to the TARGET_CLASS)
# must be preceded with an empty string, so that MainInvoker will know
# you are giving a class name.  MainInvoker will invoke the normal 
# static main(String[]) method of each such class.  
# By default, MainInvoker will just run TARGET_CLASS with no args.
# Example that runs just the TARGET_CLASS with the specified arguments:
#INVOC_ADDL_ARGS='-silent false'
# Example that runs the TARGET_CLASS plus a WebServer:
#INVOC_ADDL_ARGS='"" org.hsqldb.WebServer'
# Note the empty string preceding the class name.
# Example that starts TARGET_CLASS with an argument + a WebServer +
# your own application with its args (i.e., the HSQLDB Servers are
# "embedded" in your application).  (Set SERVER_ADDL_CLASSPATH too).:
#INVOC_ADDL_ARGS='-silent false "" org.hsqldb.WebServer "" com.acme.Stone --env prod localhost'
# Example to run a non-TLS server in same JVM with a TLS server.  In this
# case, TARGET_CLASS is Server which will run in TLS mode by virtue of 
# setting TLS_KEYSTORE and TLS_PASSWORD above.  The "additional" Server
# here overrides the 'tls' and 'port' settings:
#INVOC_ADDL_ARGS="'' org.hsqldb.Server -port 9002 -tls false"
# Note that you use nested quotes to group arguments and to specify the
# empty-string delimiter.

# For TLS encryption for your Server, set these two variables.
# N.b.:  If you set these, then make this file unreadable to non-root users!!!!
# See the TLS chapter of the HSQLDB User Guide, paying attention to the 
# security warning(s).
# If you are running with a private server cert, then you will also need to 
# set "truststore" in the your SqlTool config file (location is set by the
# AUTH_FILE variable in this file, or it must be at the default location for 
# HSQLDB_OWNER).
#TLS_KEYSTORE=/path/to/jks/server.store
#TLS_PASSWORD=password

# Any JVM args for the invocation of the JDBC client used to verify DB
# instances and to shut them down (SqlToolSprayer).
# This example specifies the location of a private trust store for TLS 
# encryption.
# For multiple args, put quotes around entire value.
#CLIENT_JVMARGS=-Djavax.net.debug=ssl

# Any JVM args for the server.
# For multiple args, put quotes around entire value.
#SERVER_JVMARGS=-Xmx512m

                3. Either copy HSQLDB_OWNER's sqltool.rc file into root's home directory, or set the value of AUTH_FILE to the absolute path of HSQLDB_OWNER's sqltool.rc file. This file is read (for stops) directly by root, even if you run hsqldb as non-root (by setting HSQLDB_OWNER in the config file). If you copy the file, make sure to use chmod to restrict permissions on the new copy. (The init script now enforces permissions on this file).

                4. Edit your server.properties file. For every server.database.X that you have defined, set a property of name server.urlid.X to the urlid for an Administrative user for that database instance.

                  Example 3.1. server.properties fragment

                      server.database.0=file://home/hsqldb/data/db1
    server.urlid.0=localhostdb1

                  Warning

                  Make sure to add a urlid for each and every database instance. If you don't then the init script will never know about databases that become inaccessible and will give false diagnostics.

                  For this example, you would need to define the urlid localhostdb1 in your sqltool.rc file.

                  Example 3.2. example sqltool.rc stanza

                      urlid localhostdb1
    url jdbc:hsqldb:hsql://localhost
    username sa
    password secret

                5. Verify that the init script works.

                  Just run 

                      /path/to/hsqldb
                  as root to see the arguments you may use. Notice that you can run 

                      /path/to/hsqldb status

                  at any time to see whether your HSQLDB Server is running.

                  Re-run the script with each of the possible arguments to really test it good. If anything doesn't work right, then see the Troubleshooting the Init Script section.

                6. Tell your OS to run the init script upon system startup and shutdown. If you are using a UNIX variant that has /etc/rc.conf or /etc/rc.conf.local (like BSD variants and Gentoo), you must set "hsqldb_enable" to "YES" in either of those files. (Just run cd /etc; ls rc.conf rc.conf.local to see if you have one of these files). For good UNIXes that use System V style init, you must set up hard links or soft links either manually or with management tools (such as chkconfig or insserv) or Gui's (like run level editors).

                  This paragraph is for Mac OS X users only. If you followed the instructions above, your init script should reside at /Library/StartupItems/hsqldb/hsqldb. Now copy the file StartupParameters.plist from the directory src/org.hsqldb/sample of your HSQLDB distribution to the same directory as the init script. As long as these two files reside in /Library/StartupItems/hsqldb, your init script is active (for portability reasons, it doesn't check for a setting in /etc/hostconfig). You can run it as a Startup Item by running 

                      SystemStarter {start|stop|restart} Hsqldb
                  Hsqldb is the service name. See the man page for SystemStarter. To disable the init script, wipe out the /Library/StartupItems/hsqldb directory. Hard to believe, but the Mac people tell me that during system shutdown the Startup Items don't run at all. Therefore, if you don't want your data corrupted, make sure to run "SystemStarter stop Hsqldb" before shutting down your Mac.

                Follow the examples in the config file to add additional classes to the server JVM's classpath and to execute additional classes in your JVM. (See the SERVER_ADDL_CLASSPATH and INVOC_ADDL_ARGS items).

                Troubleshooting the Init Script

                Do a ps to look for processes containing the string hsqldb, and try to connect to the database from any client. If the init script starts up your database successfully, but incorrectly reports that it has not, then your problem is with specification of urlid(s) or SqlTool setup. If your database really did not start, then skip to the next paragraph. Verify that the urlid(s) listed in the server.properties or webserver.properties are correct. and verify that you can run SqlTool as root to connect to the instances. (For the latter test, use the --rcfile switch if you are setting AUTH_FILE in the init script config file).

                If your database really is not starting, then verify that you can su to the database owner account and start the database. The command su USERNAME -c ... won't work on most UNIXes unless the target user has a real login shell. Therefore, if you try to tighten up security by disabling this user's login shell, you will break the init script. If these possibilities don't pan out, then debug the init script or seek help, as described below.

                To debug the init script, run it in verbose mode to see exactly what is happening (and perhaps manually run the steps that are suspect). To run an init script (in fact, any sh shell script) in verbose mode, use sh with the -x or -v switch, like 

                    sh -x path/to/hsqldb start
                See the man page for sh if you don't know the difference between -v and -x.

                If you want troubleshooting help, use the HSQLDB lists/forums or email me at blaine.simpson@admc.com. If you email me, make sure to include the revision number from your hsqldb init script (it's towards the top in the line that starts like "# $Id:"), and the output of a run of 

                    sh -x path/to/hsqldb start > /tmp/hstart.log 2>&1

                Purpose

                Many questions repeatedly asked in Forums and mailing lists are answered in this guide. If you want to use HSQLDB with your application, you should read this guide. This document covers system related issues. For issues related to SQL see the SQL Issues chapter.

                Connections

                The normal method of accessing an HSQLDB database is via the JDBC Connection interface. An introduction to different methods of providing database services and accessing them can be found in the SQL Issues chapter. Details and examples of how to connect via JDBC are provided in our JavaDoc for jdbcConnection.

                Version 1.7.2 introduced a uniform method of distinguishing between different types of connection, alongside new capabilities to provide access to multiple databases. The common driver identifier is jdbc:hsqldb: followed by a protocol identifier (mem: file: res: hsql: http: hsqls: https:) then followed by host and port identifiers in the case of servers, then followed by database identifier.

                Table 4.1. Hsqldb URL Components

                Driver and ProtocolHost and PortDatabase
                jdbc:hsqldb:mem:
                		not available
                accounts

                Lowercase, single-word identifier creates the in-memory database when the first connection is made. Subsequent use of the same Connection URL connects to the existing DB.

                The old form for the URL, jdbc:hsqldb:. creates or connects to the same database as the new form for the URL, jdbc:hsqldb:mem:.

                jdbc:hsqldb:file:
                		not available
                mydb
                /opt/db/accounts
                C:/data/mydb

                The file path specifies the database file. In the above examples the first one refers to a set of mydb.* files in the directory where the javacommand for running the application was issued. The second and third examples refer to absolute paths on the host machine.

                jdbc:hsqldb:res:
                		not available
                /adirectory/dbname
                Database files can be loaded from one of the jars specified as part of the Java command the same way as resource files are accessed in Java programs. The /adirectory above stands for a directory in one of the jars.
                jdbc:hsqldb:hsql:
                jdbc:hsqldb:hsqls:
                jdbc:hsqldb:http:
                jdbc:hsqldb:https:
                //localhost
                //192.0.0.10:9500
                //dbserver.somedomain.com
                /an_alias
                /enrollments
                /quickdb

                The host and port specify the IP address or host name of the server and an optional port number. The database to connect to is specified by an alias. This alias is a lowercase string defined in the server.properties file to refer to an actual database on the file system of the server or a transient, in-memory database on the server. The following example lines in server.properties or webserver.properties define the database aliases listed above and accessible to clients to refer to different file and in-memory databases.

                    database.0=file:/opt/db/accounts
    dbname.0=an_alias

    database.1=file:/opt/db/mydb
    dbname.1=enrollments

    database.2=mem:adatabase
    dbname.2=quickdb

                The old form for the server URL, e.g., jdbc:hsqldb:hsql//localhost connects to the same database as the new form for the URL, jdbc:hsqldb:hsql//localhost/ where the alias is a zero length string. In the example below, the database files lists.* in the /home/dbmaster/ directory are associated with the empty alias:

                    database.3=/home/dbmaster/lists
    dbname.3=

                Connection properties

                Each new JDBC Connection to a database can specify connection properties. The properties user and password are always required. In 1.8.0 the following optional properties can also be used.

                Connection properties are specified either by establishing the connection via the:

                    DriverManager.getConnection (String url, Properties info);

                method call, or the property can be appended to the full Connection URL.

                Table 4.2. Connection Properties

                get_column_nametruecolumn name in ResultSet

                This property is used for compatibility with other JDBC driver implementations. When true (the default), ResultSet.getColumnName(int c) returns the underlying column name

                When false, the above method returns the same value as ResultSet.getColumnLabel(int column) Example below:

                    jdbc:hsqldb:hsql://localhost/enrollments;get_column_name=false

                When a ResultSet is used inside a user-defined stored procedure, the default, true, is always used for this property.

                ifexistsfalseconnect only if database already exists

                Has an effect only with mem: and file: database. When true, will not create a new database if one does not already exist for the URL.

                When false (the default), a new mem: or file: database will be created if it does not exist.

                Setting the property to true is useful when troubleshooting as no database is created if the URL is malformed. Example below:

                    jdbc:hsqldb:file:enrollments;ifexists=true
                shutdownfalseshut down the database when the last connection is closed

                This mimics the behaviour of 1.7.1 and older versions. When the last connection to a database is closed, the database is automatically shut down. The property takes effect only when the first connection is made to the database. This means the connection that opens the database. It has no effect if used with subsequent, simultaneous connections.

                This command has two uses. One is for test suites, where connections to the database are made from one JVM context, immediately followed by another context. The other use is for applications where it is not easy to configure the environment to shutdown the database. Examples reported by users include web application servers, where the closing of the last connection conisides with the web app being shut down.

                In addition, when a connection to an in-process database creates a new database, or opens an existing database (i.e. it is the first connection made to the database by the application), all the user-defined database properties can be specified as URL properties. This can be used to specify properties to enforce more strict SQL adherence, or to change cache_scale or similar properties before the database files are created. However, for new databases, it is recommended to use the SET PROPERTY command for such settings.

                Properties Files

                HSQLDB relies on a set of properties files for different settings. Since 1.7.0 property naming has been streamlined and a number of new properties have been introduced.

                In all properties files, values are case-sensitive. All values apart from names of files or pages are required in lowercase (e.g. server.silent=FALSE will have no effect, but server.silent=false will work).

                The properties files and the settings stored in them are as follows:

                Table 4.3. Hsqldb Server Properties Files

                File NameLocationFunction
                server.propertiesthe directory where the command to run the Server class is issuedsettings for running HSQLDB as a database server communicating with the HSQL protocol
                webserver.propertiesthe directory where the command to run the WebServer class is issuedsettings for running HSQLDB as a database server communicating with the HTTP protocol
                <dbname>.propertiesthe directory where all the files for a database are locatedsettings for each particular database

                Properties files for running the servers are not created automatically. You should create your own files that contain server.property=value pairs for each property.

                The properties file for each database is generated by the database engine. This file can be edited after closing the database. In 1.8.0, most of these properties can be changed via SQL commands.

                Server and Web Server Properties

                In both server.properties and webserver.properties files, supported values and their defaults are as follows:

                Table 4.4. Property File Properties

                ValueDefaultDescription
                server.database.0testthe path and file name of the first database file to use
                server.dbname.0""lowercase server alias for the first database file
                server.urlid.0NONESqlTool urlid used by UNIX init script. (This property is not used if your are running Server/Webserver on a platform other than UNIX, or of you are not using our UNIX init script).
                server.silenttrueno extensive messages displayed on console
                server.tracefalseJDBC trace messages displayed on console

                In 1.8.0, each server can serve up to 10 different databases simultaneously. The server.database.0 property defines the filename / path whereas the server.dbname.0 defines the lowercase alias used by clients to connect to that database. The digit 0 is incremented for the second database and so on. Values for the server.database.{0-9} property can use the mem:, file: or res: prefixes and properties as discussed above under CONNECTIONS. For example, 

                    database.0=mem:temp;sql.enforce_strict_size=true;

                Values specific to server.properties are:

                Table 4.5. Server Property File Properties

                ValueDefaultDescription
                server.port9001 (normal) or 554 (if TLS encrypted)TCP/IP port used for talking to clients. All databases are served on the same port.
                server.no_system_exittrueno System.exit() call when the database is closed

                Values specific to webserver.properties are:

                Table 4.6. WebServer Property File Properties

                ValueDefaultDescription
                server.port80TCP/IP port used for talking to clients
                server.default_pageindex.htmlthe default web page for server
                server.root./the location of served pages
                .<extension>?multiple entries such as .html=text/html define the mime types of the static files served by the web server. See the source for WebServer.java for a list.

                All the above values can be specified on the command line to start the server by omitting the server. prefix.

                Starting a Server from your application

                If you want to start the server from within your application, as opposed to the command line or batch files, you should create an instance of Server or Web Server, then assign the properties in the form of a String and start the Server. An example of this can be found in the org.hsqldb.test.TestBase source.

                Note

                Upgrading: If you have existing custom properties files, change the values to the new naming convention. Note the use of digits at the end of server.database.n and server.dbname.n properties.

                Individual Database Properties

                Each database has its own <dbname>.properties file as part of a small group of files which also includes <dbname>.script and <dbname>.data. The properties files contain key/value pairs for some important settings.

                In version 1.8.0 a new SQL command allows most database properties to be modified as follows:

                    SET PROPERTY "property_name" property_value

                Properties that can be modified via SET PROPERTY are indicated in the table below. Other properties are indicated as PROPERTIES FILE ONLY and can be modified only by editing the .properties file after a shutdown and before a restart. Only the user-defined values listed below should ever be modified. Changing any other value could result in unexpected malfunction in database operations. Most of these values have been introduced for the new features since 1.7.0:

                Table 4.7. Database-specific Property File Properties

                ValueDefaultDescription
                readonlyfalsewhole database is read-only

                When true, the database cannot be modified in use. This setting can be changed to true if the database is to be opened from a CD. Prior to changing this setting, the database should be closed with the SHUTDOWN COMPACT command to ensure consistency and compactness of the data. (PROPERTIES FILE ONLY) but can be used as a connection property to open a normal database as readonly.

                hsqldb.files_readonlyfalsedatabase files will not be written to

                When true, data in MEMORY tables can be modified and new MEMORY tables can be added. However, these changes are not saved when the database is shutdown. CACHED and TEXT tables are always readonly when this setting is true. (PROPERTIES FILE ONLY)

                hsqldb.cache_file_scale1Set larger data file limits. Once set, the limit will go up to 8GB.

                This property can be set to 8 to increase the size limit of the .data file from 2GB to 8GB. To apply the change to an existing database, SHUTDOWN SCRIPT should be performed first, then the property=value line below should be added to the .properties file before reopening the database. 

                hsqldb.cache_file_scale=8

                The property can be set with the SQL command (as opposed to changing the value in the properties file) when the database has no CACHED tables (e.g. a new database). (SET PROPERTY)

                sql.enforce_sizefalsetrimming and padding string columns

                This property is no longer supported. Use sql.enforce_sctrict_size

                sql.enforce_strict_sizefalsesize enforcement and padding string columns

                Conforms to SQL standards for size and precision of data types. When true, all CHARACTER, VARCHAR, NUMERIC and DECIMAL values that are in a row affected by an INSERT INTO or UPDATE statement are checked against the size specified in the SQL table definition. An exception is thrown if the value is too long. Also all CHARACTER values that are shorter than the specified size are padded with spaces. TIMESTAMP(0) and TIMESTAMP(6) are also allowed in order to specify the subsecond resolution of the values. When false (default), stores the exact string that is inserted. (SET PROPERTY)

                sql.tx_no_multi_rewritefalsetransaction management

                In the default READ_UNCOMMITED mode, a transaction can write over rows inserted or updated by another uncommitted transaction. Setting this property to true will raise an exception when such a write is attempted (SET PROPERTY)

                hsqldb.cache_scale14memory cache exponent

                Indicates the maximum number of rows of cached tables that are held in memory, calculated as 3 *(2**value) (three multiplied by (two to the power value)). The default results in up to 3*16384 rows from all cached tables being held in memory at any time.

                The value can range between 8-18. (SET PROPERTY). If the value is set via SET PROPERTY then it becomes effective after the next database SHUTDOWN or CHECKPOINT. (SET PROPERTY)

                hsqldb.cache_size_scale10memory cache exponent

                Indicates the average size of each row in the memory cache used with cached tables, calculated as 2**value (two to the power value). This result value is multiplied by the maximum number of rows defined by hsqldb.cache_scale to form the maximum number of bytes for all the rows in memory cache. The default results in 1024 bytes per row. This default, combined with the default number of rows, results in approximately 50MB of the .data file to be stored in the memory cache.

                The value can range between 6-20. (SET PROPERTY). If the value is set via SET PROPERTY then it becomes effective after the next database SHUTDOWN or CHECKPOINT. (SET PROPERTY)

                hsqldb.log_size200size of log when checkpoint is performed

                The value is the size in megabytes that the .log file can reach before an automatic checkpoint occurs. A checkpoint and rewrites the .script file and clears the .log file. The value can be changed via the SET LOGSIZE nnn SQL command.

                runtime.gc_interval0forced garbage collection

                This setting forces garbage collection each time a set number of result set row or cache row objects are created. The default, "0" means no garbage collection is forced by the program.

                This should not be set when the database engine is acting as a server inside an exclusive JVM. The setting can be useful when the database is used in-process with the application with some Java Runtime Environments (JRE's). Some JRE's increase the size of the memory heap before doing any automatic garbage collection. This setting would prevent any unnecessary enlargement of the heap. Typical values for this setting would probably be between 10,000 to 100,000. (PROPERTIES FILE ONLY)

                hsqldb.nio_data_filetrueuse of nio access methods for the .data file

                When HSQLDB is compiled and run in Java 1.4 or higher, setting this property to false will avoid the use of nio access methods, resulting in somewhat reduced speed. If the data file is larger than 256MB when it is first opened, nio access methods are not used. Also, if the file gets larger than the amount of available computer memory that needs to be allocated for nio access, non-nio access methods are used.

                (SET PROPERTY). If used before defining any CACHED table, it applies to the current session, otherwise it comes to effect after a SHUTDOWN and restart or CHECKPOINT.

                hsqldb.default_table_typememorytype of table created with unqualified CREATE TABLE

                The CREATE TABLE command results in a MEMORY table by default. Setting the value "cached" for this property will result in a cached table by default. The qualified forms such as CREATE MEMORY TABLE or CREATE CACHED TABLE are not affected at all by this property. (SET PROPERTY)

                hsqldb.applog0application logging level

                The default level 0 indicates no logging. Level 1 results in events related to persistence to be logged, including any failures. The events are logged in a file ending with .app.log

                textdb.*0default properties for new text tables

                Properties that override the database engine defaults for newly created text tables. Settings in the text table SET <tablename> SOURCE <source string> command override both the engine defaults and the database properties defaults. Individual textdb.* properties are listed in the Text Tables chapter. (SET PROPERTY)

                When connecting to an in-process database creates a new database, or opens an existing database (i.e. it is the first connection made to the database by the application), all the user-defined database properties listed in this section can be specified as URL properties.

                Note

                Upgrading: From 1.7.0, the location of the database files can no longer be overridden by paths defined in the properties file. All files belonging to a database should reside in the same directory.

                The property sql.compare_in_locale=true is no longer supported. If the line exists in a .properties file, it will switch the database to the collation for the current default. See the SET DATABASE COLLATION[2] command.

                When HSQLDB is used in OpenOffice.org, some property values will have a different default. The properties and values are:

                hsqldb.default_table_type=cached hsqldb.cache_scale=13 hsqldb.log_size=10; hsqldb.nio_data_file=false sql.enforce_strict_size=true

                SQL Commands for Database Properties

                There are some database properties that are set with dedicated SQL commands beginning with SET.

                Table 4.8. SQL command properties

                SET WRITE_DELAY {{TRUE | FALSE} | <seconds> | <milliseconds> MILLIS

                The default is TRUE and indicates that the changes to the database that have been logged are synched to the file system once every 20 seconds. FALSE indicates there is no delay and at each commit a file synch operation is performed. Numeric values from 0 can also be specified for the synch delay.

                The purpose of this command is to control the amount of data loss in case of a total system crash. A delay of 1 second means at most the data written to disk during the last second before the crash is lost. All data written prior to this has been synced and should be recoverable

                This setting should be specified on the basis of the reliability of the hardware used for running the database engine, the type of disk system used, the possibility of power failure etc. Also the nature of the data stored should be considered.

                In general, when the system is very reliable, the setting can be left to the default. If it is not very reliable, or the data is critical a setting of 1 or 2 seconds would suffice. Only in the worst case scenario or with the most critical data should a setting of 0 or FALSE be specified as this will slow the engine down to the speed at which the file synch operation can be performed by the disk subsystem.

                Values down to 10 millisconds can be specified by adding MILLIS to the command, but in practice a delay of 100 milliseconds provides 99.99999% reliability with an average one system crash per 6 days.

                SET LOG_SIZE <numeric value>

                The engine writes out a log of all the changes to the database as they occur. This log is synched to the disk based on the WRITE_DELAY property above. The log is never reused unless there is an abnormal termination, i.e. the database process is terminated without SHUTDOWN, or it was terminated using SHUTDOWN IMMEDIATELY.

                The default maximum size of the .log file is 200 MB. When the maximum size is reached, a CHECKPOINT operation is performed. This operation will save the other database files in a consistent state and delete the old log. A value of 0 indicates no limit for the .log file.

                SET CHECKPOINT DEFRAG <numeric value>

                When rows in CACHED tables are updated or deleted, the spaces are mostly reused. However, in time, some unused spaces are left in the .data file, especially when large tables are dropped or their structure is modified.

                A CHECKPOINT operation does not normally reclaim the empty spaces, whereas CHECKPOINT DEFRAG always does.

                This property determines when a normal CHECKPOINT, whether initiated by an administrator or when the size of the log exceeds its limit.

                The numeric value is the number of megabytes of recorded empty spaces in the .data file that would force a DEFRAG operation. Low values result in more frequent DEFRAG operations. A value of 0 indicates no automatic DEFRAG is performed. The default is 200 megabytes of lost space.

                SET REFERENTIAL INTEGRITY {TRUE | FALSE}

                This is TRUE by default. If bulk data needs to be loaded into the database, this property can be set FALSE for the duration of bulk load operation. This allows loading data for related tables in any order. The property should be set TRUE after bulk load. If the loaded data is not guaranteed to conform to the referential integrity constraints, SQL queries should be run after loading to identify and modify any non-conforming rows.

                Purpose

                Many questions repeatedly asked in Forums and mailing lists are answered in this guide. If you want to use HSQLDB with your application, you should read this guide. This document covers system related issues. For issues related to SQL see the SQL Issues chapter.

                Mode of Operation and Tables

                HSQLDB has many modes of operation and features that allow it to be used in very different scenarios. Levels of memory usage, speed and accessibility by different applications are influenced by how HSQLDB is deployed.

                Mode of Operation

                The decision to run HSQLDB as a separate server process or as an in-process database should be based on the following:

                • When HSQLDB is run as a server on a separate machine, it is isolated from hardware failures and crashes on the hosts running the application.

                • When HSQLDB is run as a server on the same machine, it is isolated from application crashes and memory leaks.

                • Server connections are slower than in-process connections due to the overhead of streaming the data for each JDBC call.

                Tables

                TEXT tables are designed for special applications where the data has to be in an interchangeable format, such as CSV. TEXT tables should not be used for routine storage of data.

                MEMORY tables and CACHED tables are generally used for data storage. The difference between the two is as follows:

                • The data for all MEMORY tables is read from the .script file when the database is started and stored in memory. In contrast the data for cached tables is not read into memory until the table is accessed. Furthermore, only part of the data for each CACHED table is held in memory, allowing tables with more data than can be held in memory.

                • When the database is shutdown in the normal way, all the data for MEMORY tables is written out to the disk. In comparison, the data in CACHED tables that has changed is written out at shutdown, plus a compressed backup of all the data in all cached tables.

                • The size and capacity of the data cache for all the CACHED tables is configurable. This makes it possible to allow all the data in CACHED tables to be cached in memory. In this case, speed of access is good, but slightly slower than MEMORY tables.

                • For normal applications it is recommended that MEMORY tables are used for small amounts of data, leaving CACHED tables for large data sets. For special applications in which speed is paramount and a large amount of free memory is available, MEMORY tables can be used for large tables as well

                Large Objects

                JDBC Clobs are supported as columns of the type LONGVARCHAR. JDBC Blobs are supported as columns of the type LONGVARBINARY. When large objects (LONGVARCHAR, LONGVARBINARY, OBJECT) are stored with table definitions that contain several normal fields, it is better to use two tables instead. The first table to contain the normal fields and the second table to contain the large object plus an identity field. Using this method has two benefits. (a) The first table can usually be created as a MEMORY table while only the second table is a CACHED table. (b) The large objects can be retrieved individually using their identity, instead of getting loaded into memory for finding the rows during query processing. An example of two tables and a select query that exploits the separation between the two follows:

                CREATE MEMORY TABLE MAINTABLE(MAINID INTEGER, ......);
                CREATE CACHED TABLE LOBTABLE(LOBID INTEGER, LOBDATA LONGVARBINARY);
                SELECT * FROM (SELECT * FROM MAINTABLE <join any other table> WHERE <various conditions apply>) JOIN LOBTABLE ON MAINID=LOBID;

                The inner SELECT finds the required rows without reference to the LOBTABLE and when it has found all the rows, retrieves the required large objects from the LOBTABLE.

                Deployment context

                The files used for storing HSQLDB database data are all in the same directory. New files are always created and deleted by the database engine. Two simple principles must be observed:

                • The Java process running HSQLDB must have full privileges on the directory where the files are stored. This include create and delete privileges.

                • The file system must have enough spare room both for the 'permanent' and 'temporary' files. The default maximum size of the .log file is 200MB. The .data file can grow to up to 8GB. The .backup file can be up to 50% of the .data file. The temporary file created at the time of a SHUTDOWN COMPACT can be equal in size to the .data file.

                Memory and Disk Use

                Memory used by the program can be thought of as two distinct pools: memory used for table data, and memory used for building result sets and other internal operations. In addition, when transactions are used, memory is utilised for storing the information needed for a rollback.

                Since version 1.7.1, memory use has been significantly reduced compared to previous versions. The memory used for a MEMORY table is the sum of memory used by each row. Each MEMORY table row is a Java object that has 2 int or reference variables. It contains an array of objects for the fields in the row. Each field is an object such as Integer, Long, String, etc. In addition each index on the table adds a node object to the row. Each node object has 6 int or reference variables. As a result, a table with just one column of type INTEGER will have four objects per row, with a total of 10 variables of 4 bytes each - currently taking up 80 bytes per row. Beyond this, each extra column in the table adds at least a few bytes to the size of each row.

                The memory used for a result set row has fewer overheads (fewer variables and no index nodes) but still uses a lot of memory. All the rows in the result set are built in memory, so very large result sets may not be possible. In server mode databases, the result set memory is released from the server once the database server has returned the result set. In-process databases release the memory when the application program releases the java.sql.ResultSet object. Server modes require additional memory for returning result sets, as they convert the full result set into an array of bytes which is then transmitted to the client.

                When UPDATE and DELETE queries are performed on CACHED tables, the full set of rows that are affected, including those affected due to ON UPDATE actions, is held in memory for the duration of the operation. This means it may not be possible to perform deletes or updates involving very large numbers of rows of CACHED tables. Such operations should be performed in smaller sets.

                When transactions support is enabled with SET AUTOCOMMIT OFF, lists of all insert, delete or update operations are stored in memory so that they can be undone when ROLLBACK is issued. Transactions that span hundreds of modification to data will take up a lot of memory until the next COMMIT or ROLLBACK clears the list.

                Most JVM implementations allocate up to a maximum amount of memory (usually 64 MB by default). This amount is generally not adequate when large memory tables are used, or when the average size of rows in cached tables is larger than a few hundred bytes. The maximum amount of allocated memory can be set on the java ... command line that is used for running HSQLDB. For example, with Sun JVM version 1.3.0 the parameter -Xmx256m increases the amount to 256 MB.

                1.8.0 uses a fast cache for immutable objects such as Integer or String that are stored in the database. In most circumstances, this reduces the memory footprint still further as fewer copies of the most frequently-used objects are kept in memory.

                Cache Memory Allocation

                With CACHED tables, the data is stored on disk and only up to a maximum number of rows are held in memory at any time. The default is up to 3*16384 rows. The hsqldb.cache_scale database property can be set to alter this amount. As any random subset of the rows in any of the CACHED tables can be held in the cache, the amount of memory needed by cached rows can reach the sum of the rows containing the largest field data. For example if a table with 100,000 rows contains 40,000 rows with 1,000 bytes of data in each row and 60,000 rows with 100 bytes in each, the cache can grow to contain nearly 50,000 rows, including all the 40,000 larger rows.

                An additional property, hsqldb.cache_size_scale can be used in conjunction with the hsqldb.cache_scale property. This puts a limit in bytes on the total size of rows that are cached. When the default values is used for both properties, the limit on the total size of rows is approximately 50MB. (This is the size of binary images of the rows and indexes. It translates to more actual memory, typically 2-4 times, used for the cache because the data is represented by Java objects.)

                If memory is limited, the hsqldb.cache_scale or hsqldb.cache_size_scale database properties can be reduced. In the example above, if the hsqldb.cache_size_scale is reduced from 10 to 8, then the total binary size limit is reduced from 50MB to 12.5 MB. This will allow the number of cached rows to reach 50,000 small rows, but only 12,500 of the larger rows.

                Managing Database Connections

                In all running modes (server or in-process) multiple connections to the database engine are supported. In-process (standalone) mode supports connections from the client in the same Java Virtual Machine, while server modes support connections over the network from several different clients.

                Connection pooling software can be used to connect to the database but it is not generally necessary. With other database engines, connection pools are used for reasons that may not apply to HSQLDB.

                • To allow new queries to be performed while a time-consuming query is being performed in the background. This is not possible with HSQLDB 1.8.0 as it blocks while performing the first query and deals with the next query once it has finished it. This capability is under development and will be introduced in a future version.

                • To limit the maximum number of simultaneous connections to the database for performance reasons. With HSQLDB this can be useful only if your application is designed in a way that opens and closes connections for each small task.

                • To control transactions in a multi-threaded application. This can be useful with HSQLDB as well. For example, in a web application, a transaction may involve some processing between the queries or user action across web pages. A separate connection should be used for each HTTP session so that the work can be committed when completed or rolled back otherwise. Although this usage cannot be applied to most other database engines, HSQLDB is perfectly capable of handling over 100 simultaneous HTTP sessions as individual JDBC connections.

                An application that is not both multi-threaded and transactional, such as an application for recording user login and logout actions, does not need more than one connection. The connection can stay open indefinitely and reopened only when it is dropped due to network problems.

                When using an in-process database with versions prior to 1.7.2 the application program had to keep at least one connection to the database open, otherwise the database would have been closed and further attempts to create connections could fail. This is not necessary since 1.7.2, which does not automatically close an in-process database that is opened by establishing a connection. An explicit SHUTDOWN command, with or without an argument, is required to close the database. In version 1.8.0 a connection property can be used to revert to the old behaviour.

                When using a server database (and to some extent, an in-process database), care must be taken to avoid creating and dropping JDBC Connections too frequently. Failure to observe this will result in unsuccessful connection attempts when the application is under heavy load.

                Upgrading Databases

                Any database not produced with the release version of HSQLDB 1.8.0 must be upgraded to this version. This includes databases created with the RC versions of 1.8.0. The instructions under the Upgrading Using the SCRIPT Command section should be followed in all cases.

                Once a database is upgraded to 1.8.0, it can no longer be used with Hypersonic or previous versions of HSQLDB.

                There may be some potential legacy issues in the upgrade which should be resolved by editing the .script file:

                • Version 1.8.0 does not accept duplicate names for indexes that were allowed before 1.7.2.

                • Version 1.8.0 does not accept duplicate names for table columns that were allowed before 1.7.0.

                • Version 1.8.0 does not create the same type of index for foreign keys as versions before 1.7.2.

                • Version 1.8.0 does not accept table or column names that are SQL identifiers without double quoting.

                Upgrading Using the SCRIPT Command

                To upgrade from 1.7.2 or 1.7.3 to 1.8.0, simply issue the SET SCRIPTFORMAT TEXT and SHUTDOWN SCRIPT commands with the old version, then open with the new version of the engine. The upgrade is then complete.

                To upgrade from older version database files (1.7.1 and older) that do not contain CACHED tables, simple SHUTDOWN with the older version and open with the new version. If there is any error in the .script file, try again after editing the .script file.

                To upgrade from older version database files (1.7.1 and older) that contain CACHED tables, use the SCRIPT procedure below. In all versions of HSQLDB and Hypersonic 1.43, the SCRIPT 'filename' command (used as an SQL query) allows you to save a full record of your database, including database object definitions and data, to a file of your choice. You can export a script file using the old version of the database engine and open the script as a database with 1.8.0.

                Procedure 5.1. Upgrade Using SCRIPT procedure

                1. Open the original database in the old version of DatabaseManager

                2. Issue the SCRIPT command, for example SCRIPT 'newversion.script' to create a script file containing a copy of the database.

                3. Use the 1.8.0 version of DatabaseManager to create a new database, in this example 'newversion' in a different directory.

                4. SHUTDOWN this database.

                5. Copy the newversion.script file from step 2 over the file of the same name for the new database created in 4.

                6. Try to open the new database using DatabaseManager.

                7. If there is any inconsistency in the data, the script line number is reported on the console and the opening process is aborted. Edit and correct any problems in the newversion.script before attempting to open again. Use the guidelines in the next section (Manual Changes to the .script File). Use a programming editor that is capable of handling very large files and does not wrap long lines of text.

                Manual Changes to the .script File

                In 1.8.0 the full range of ALTER TABLE commands is available to change the data structures and their names. However, if an old database cannot be opened due to data inconsistencies, or the use of index or column names that are not compatible with 1.8.0, manual editing of the SCRIPT file can be performed.

                The following changes can be applied so long as they do not affect the integrity of existing data.

                • Names of tables, columns and indexes can be changed.

                • CREATE UNIQUE INDEX ... to CREATE INDEX ... and vice versa

                  A unique index can always be converted into a normal index. A non-unique index can only be converted into a unique index if the table data for the column(s) is unique in each row.

                • NOT NULL

                  A not-null constraint can always be removed. It can only be added if the table data for the column has no null values.

                • PRIMARY KEY

                  A primary key constraint can be removed or added. It cannot be removed if there is a foreign key referencing the column(s).

                • COLUMN TYPES

                  Some changes to column types are possible. For example an INTEGER column can be changed to BIGINT, or DATE, TIME and TIMESTAMP columns can be changed to VARCHAR.

                After completing the changes and saving the modified *.script file, you can open the database as normal.

                Backing Up Databases

                The data for each database consists of up to 5 files in the same directory. The endings are *.properties, *.script, *.data, *.backup and *.log (a file with the *.lck ending is used for controlling access to the database and should not be backed up). These should be backed up together. The files can be backed up while the engine is running but care should be taken that a CHECKPOINT or SHUTDOWN operation does not take place during the backup. It is more efficient to perform the backup immediately after a CHECKPOINT. The *.data file can be excluded from the backup. In this case, when restoring, a dummy *.data file is needed which can be an empty, 0 length file. The engine will expand the *.backup file to replace this dummy file if the backup is restored. If the *.data file is not backed up, the *.properties file may have to be modified to ensure it contain modified=yes instead of modified=no prior to restoration. If a backup immediately follows a checkpoint, then the *.log file can also be excluded, reducing the significant files to *.properties, *.script and *.backup. Normal backup methods, such as archiving the files in a compressed bundle can be used.

                Importing from a Text Table file

                Text Table support for HSQLDB was originally developed by Bob Preston independently from the Project. Subsequently Bob joined the Project and incorporated this feature into version 1.7.0, with a number of enhancements, especially the use of conventional SQL commands for specifying the files used for Text Tables.

                In a nutshell, Text Tables are CSV or other delimited files treated as SQL tables. Any ordinary CSV or other delimited file can be used. The full range of SQL queries can be performed on these files, including SELECT, INSERT, UPDATE and DELETE. Indexes and unique constraints can be set up, and foreign key constraints can be used to enforce referential integrity between Text Tables themselves or with conventional tables.

                HSQLDB with Text Table support is the only comprehensive solution that employs the power of SQL and the universal reach of JDBC to handle data stored in text files and will have wide-ranging use way beyond the currently established Java realm of HSQLDB.

                Goals of the Implementation

                1. We aimed to finalise the DDL for Text Tables so that future releases of HSQLDB use the same DDL scripts.

                2. We aimed to support Text Tables as GLOBAL TEMPORARY or GLOBAL BASE tables in the SQL domain.

                The Implementation

                Definition of Tables

                Text Tables are defined similarly to conventional tables with the added TEXT keyword:

                    CREATE TEXT TABLE <tablename> (<column definition> [<constraint definition>])

                In addition, a SET command specifies the file and the separator character that the Text table uses:

                    SET TABLE <tablename> SOURCE <quoted_filename_and_options> [DESC]

                Text Tables cannot be created in memory-only databases (databases that have no script file).

                Scope and Reassignment

                • A Text table without a file assigned to it is READ ONLY and EMPTY.

                • A Temporary Text table has the scope and the lifetime of the SQL session (a JDBC Connection).

                • Reassigning a Text Table definition to a new file has implications in the following areas:

                  1. The user is required to be an administrator.

                  2. Existing transactions are committed at this point.

                  3. Constraints, including foreign keys referencing this table, are kept intact. It is the responsibility of the administrator to ensure their integrity.

                  From version 1.7.2 the new source file is scanned and indexes are built when it is assigned to the table. At this point any violation of NOT NULL, UNIQUE or PRIMARY KEY constrainst are caught and the assignment is aborted. However, foreign key constraints are not checked at the time of assignment or reassignment of the source file.

                Null Values in Columns of Text Tables

                This has changed since 1.7.2 to support both null values and empty strings.

                • Empty fields are treated as NULL. These are fields where there is nothing or just spaces between the separators.

                • Quoted empty strings are treated as empty strings.

                Configuration

                The default field separator is a comma (,). A different field separator can be specified within the SET TABLE SOURCE statement. For example, to change the field separator for the table mytable to a vertical bar, place the following in the SET TABLE SOURCE statement, for example:

                    SET TABLE mytable SOURCE "myfile;fs=|"

                Since HSQLDB treats CHAR's, VARCHARs, and LONGVARCHARs the same, the ability to assign different separators to the latter two is provided. When a different separator is assigned to a VARCHAR or LONGVARCHAR field, it will terminate any CSV field of that type. For example, if the first field is CHAR, and the second field LONGVARCHAR, and the separator fs has been defined as the pipe (|) and vs as the period (.) then the data in the CSV file for a row will look like:

                    First field data|Second field data.Third field data

                The following example shows how to change the default separator to the pipe (|), VARCHAR separator to the period (.) and the LONGVARCHAR separator to the tilde (~). Place the following within the SET TABLE SOURCE statement, for example:

                    SET TABLE mytable SOURCE "myfile;fs=|;vs=.;lvs=~"

                HSQLDB also recognises the following special indicators for separators:

                special indicators for separators

                \semi

                semicolon

                \quote

                qoute

                \space

                space character

                \apos

                apostrophe

                \n

                newline - Used as an end anchor (like $ in regular expressions)

                \r

                carriage return

                \t

                tab

                \\

                backslash

                \u####

                a Unicode character specified in hexadecimal

                Furthermore, HSQLDB provides csv file support with three additional boolean options: ignore_first, quoted and all_quoted. The ignore_first option (default false) tells HSQLDB to ignore the first line in a file. This option is used when the first line of the file contains column headings. The all_quoted option (default false) tells the program that it should use quotes around all character fields when writing to the source file. The quoted option (default true) uses quotes only when necessary to distinguish a field that contains the separator character. It can be set to false to prevent the use of quoting altogether and treat quote characters as normal characters. These options may be specified within the SET TABLE SOURCE statement:

                    SET TABLE mytable SOURCE "myfile;ignore_first=true;all_quoted=true"

                When the default options all_quoted= false and quoted=true are in force, fields that are written to a line of the csv file will be quoted only if they contain the separator or the quote character. The quote character is doubled when used inside a string. When all_quoted=false and quoted=false the quote character is not doubled. With this option, it is not possible to insert any string containing the separator into the table, as it would become impossible to distinguish from a separator. While reading an existing data source file, the program treats each individual field separately. It determines that a field is quoted only if the first character is the quote character. It interprets the rest of the field on this basis.

                The character encoding for the source file is ASCII by default. To support UNICODE or source files preprared with different encodings this can be changed to UTF-8 or any other encoding. The default is encoding=ASCII and the option encoding=UTF-8 or other supported encodings can be used.

                Finally, HSQLDB provides the ability to read a text file from the bottom up and making them READ ONLY, by placing the keyword "DESC" at the end of the SET TABLE SOURCE statement:

                    SET TABLE mytable SOURCE "myfile" DESC

                This feature provides functionality similar to the Unix tail command, by re-reading the file each time a select is executed. Using this feature sets the table to read-only mode. Afterwards, it will no longer be possible to change the read-only status with SET TABLE <tablename> READONLY TRUE.

                Text table source files are cached in memory. The maximum number of rows of data that are in memory at any time is controlled by the textdb.cache_scale property. The default value for textdb.cache_scale is 10 and can be changed by setting the property in the .properties file for the database. The number of rows in memory is calculated as 3*(2**scale), which translates to 3072 rows for the default textdb.cache_scale setting (10). The property can also be set for individual text tables:

                    SET TABLE mytable SOURCE "myfile;ignore_first=true;all_quoted=true;cache_scale=12"

                Disconnecting Text Tables

                The following describes behaviour present in 1.8.0.8 and later.

                Text tables may be disconnected from their underlying data source, i.e. the text file.

                You can explicitly disconnect a text table from its file by issuing the following statement: 

                  SET TABLE mytable SOURCE OFF

                Subsequently, mytable will be empty and read-only. However, the data source description will be preserved, and the table can be re-connected to it with 

                  SET TABLE mytable SOURCE ON

                When a database is opened, if the source file for an existing text table is missing the table remains disconnected from its data source, but the source sescription is preserved. This allows the missing source file to be added to the directory and the table re-connected to it with the above command.

                Text File Issues

                Text File Issues

                • File locations are restricted to below the directory that contains the database, unless the textdb.allow_full_path property is set true in the database properties file.

                • Blank lines are allowed anywhere in the text file, and are ignored.

                • The file location for a text table created with

                      SELECT <select list> INTO TEXT <tablename> FROM

                  is the directory that contains the database and the file name is based on the table name. The table name is converted into the file name by replacing all the non-alphanumeric characters with the underscore character, conversion into lowercase, and adding the ".csv" suffix.

                • It is possible to define a primay key or identity column for text tables.

                • When a table source file is used with the ignore_first=true option, the first, ignored line is replaced with a blank line after a SHUTDOWN COMPACT.

                • An existing table source file may include CHARACTER fields that do not begin with the quote character but contain instances of the quote character. These fields are read as literal strings. Alternatively, if any field begins with the quote character, then it is interpreted as a quoted string that should end with the quote character and any instances of the quote character within the string is doubled. When any field containing the quote character or the separator is written out to the source file by the program, the field is enclosed in quote character and any instance of the quote character inside the field is doubled.

                • Inserts or updates of CHARACTER type field values are allowed with strings that contains the linefeed or the carriage return character. This feature is disabled when both quoted and all_quoted properties are false.

                • ALTER TABLE commands that add or drop columns are not supported with non-empty text tables.

                Text File Global Properties

                • textdb.quoted

                • textdb.all_quoted

                • textdb.cache_scale

                • textdb.allow_full_path

                Importing a Text Table file in to a Traditional (non-Text Table) Table

                The directory src/org/hsqldb/sample in your HSQLDB distibution contains a file named load_binding_lu.sql. This is a working SQL file which imports a pipe-delimited text file from the database's file directory into an existing normal table. You can edit a copy of this file and use it directly with SqlTool, or you can use the SQL therein as a model (using any SQL client at all).

                The instructions in this document are liable to change at any time. In particular, we will be changing the method to supply the server-side certificate password.

                Requirements

                Hsqldb TLS Support Requirements

                • Sun Java 2.x and up. (This is probably possible with IBM's Java, but I don't think anybody has attempted to run HSQLDB with TLS under IBM's Java, and I'm sure that nobody in the HSQLDB Development Group has documented how to set up the environment).

                • If Java 2.x or 3.x, then you will need need to install JSSE. Your server and/or client will start up much slower than that of Java 4.x users. Client-side users will not be able to use the https: JDBC protocol (because the https protocol handler is not implemented in 2.x/3.x Java JSSE; if there is demand, we could work around this).

                • A JKS keystore containing a private key, in order to run a server.

                • If you are running the server side, then you'll need to run a HSQLDB Server or WebServer. It doesn't matter if the underlying database instances are new, and it doesn't matter if you are making a new Server configuration or encrypting an existing Server configuration. (You can turn encryption on and off at will).

                • You need a HSQLDB jar file that was built with JSSE present. If you got your HSQLDB 1.7.2 distribution from us, you are all set, because we build with Java 1.4 (which contains JSSE). If you build your own jar file with Java 1.3, make sure to install JSSE first.

                Encrypting your JDBC connection

                At this time, only 1-way, server-cert encryption is tested.

                Client-Side

                Just use one of the following protocol prefixes.

                Hsqldb TLS URL Prefixes

                • jdbc:hsqldb:hsqls://

                • jdbc:hsqldb:https://

                At this time, the latter will only work for clients running with Java 1.4.

                If the server you wish to connect to is using a certificate approved by your default trust keystores, then there is nothing else to do. If not, then you need to tell Java to "trust" the server cert. (It's a slight over-simplification to say that if the server certificate was purchased, then you are all set; if somebody "signed their own" certificate by self-signing or using a private ca certificate, then you need to set up trust).

                First, you need to obtain the cert (only the "public" part of it). Since this cert is passed to all clients, you could obtain it by writing a java client that dumps it to file, or perhaps by using openssl s_client. Since in most cases, if you want to trust a non-commercial cert, you probably have access to the server keystore, I'll show an example of how to get what you need from the server-side JKS keystore.

                You may already have an X509 cert for your server. If you have a server keystore, then you can generate a X509 cert like this.

                Example 7.1. Exporting certificate from the server's keystore

                    keytool -export -keystore server.store -alias existing_alias -file server.cer
                In this example, server.cer is the X509 certificate that you need for the next step.

                Now, you need to add this cert to one of the system trust keystores or to a keystore of your own. See the Customizing Stores section in JSSERefGuide.html to see where your system trust keystores are. You can put private keystores anywhere you want to. The following command will add the cert to an existing keystore, or create a new keystore if client.store doesn't exist.

                Example 7.2. Adding a certificate to the client keystore

                keytool -import -trustcacerts -keystore trust.store -alias new_alias -file server.cer

                If you are making a new keystore, you probably want to start with a copy of your system default keystore which you can find somewhere under your JAVA_HOME directory (typically jre/lib/security/cacerts for a JDK, but I forget exactly where it is for a JRE).

                Unless your OS can't stop other people from writing to your files, you probably do not want to set a password on the trust keystore.

                If you added the cert to a system trust store, then you are finished. Otherwise you will need to specify your custom trust keystore to your client program. The generic way to set the trust keystore is to set the sytem property javax.net.ssl.trustStore every time that you run your client program. For example

                Example 7.3. Specifying your own trust store to a JDBC client

                    java -Djavax.net.ssl.trustStore=/home/blaine/trust.store -jar /path/to/hsqldb.jar dest-urlid
                This example runs the program SqlTool. SqlTool has built-in TLS support, however, so, for SqlTool you can set truststore on a per-urlid basis in the SqlTool configuration file.

                N.b. The hostname in your database URL must match the Common Name of the server's certificate exactly. That means that if a site certificate is admc.com, you can not use jdbc:hsqldb:hsqls://localhost or jdbc:hsqldb:hsqls://www.admc.com:1100 to connect to it.

                If you want more details on anything, see JSSERefGuide.html on Sun's site, or in the subdirectory docs/guide/security/jsse of your Java SE docs.

                Server-Side

                Get yourself a JKS keystore containing a private key. Then set the system property javax.net.ssl.keyStore to the path to that file, and javax.net.ssl.keyStorePassword to the password of the keystore (and to the private key-- they have to be the same).

                Example 7.4. Running an Hsqldb server with TLS encryption

                    java -Djavax.net.ssl.keyStorePassword=secret  \
        -Djavax.net.ssl.keyStore=/usr/hsqldb/db/db3/server.store  \
        -cp /path/to/hsqldb.jar org.hsqldb.Server

                (This is a single command that I have broken into 2 lines using my shell's \ line-continuation feature. In this example, I'm using a server.properties file so that I don't need to give arguments to specify database instances or the server endpoint).

                Caution

                Specifying a password on the command-line is definitely not secure. It's really only appropriate when untrusted users do not have any access to your computer.

                If there is any user demand, we will have a more secure way to supply the password before long.

                JSSE

                If you are running Java 4.x, then you are all set. Java 1.x users, you are on your own (Sun does not provide a JSSE that will work with 1.x). Java 2.x and 3.x users continue...

                Go to http://java.sun.com/products/jsse/index-103.html. If you agree to the terms and meet the requirements, download the domestic or global JSSE software. All you need from the software distro is the three jar files. If you have a JDK installation, then move the 3 jar files into the directory $JAVA_HOME/jre/lib/ext. If you have a JRE installation, then move the 3 jar files into the directory $JAVA_HOME/lib/ext.

                Pretty painless.

                Making a Private-key Keystore

                There are two main ways to do this. Either you can use a certificate signed by a certificate authority, or you can make your own. One thing that you need to know in both cases is, the Common Name of the cert has to be the exact hostname that JDBC clients will use in their database URL.

                CA-Signed Cert

                I'm not going to tell you how to get a CA-signed SSL certificate. That is well documented at many other places.

                Assuming that you have a standard pem-style private key certificate, here's how you can use openssl and the program DERImport to get it into a JKS keystore.

                Because I have spent a lot of time on this document already, I am just giving you an example.

                Example 7.5. Getting a pem-style private key into a JKS keystore

                openssl pkcs8 -topk8 -outform DER -in Xpvk.pem -inform PEM -out Xpvk.pk8 -nocrypt

openssl x509 -in Xcert.pem -out Xcert.der -outform DER

java DERImport new.keystore NEWALIAS Xpvk.pk8 Xcert.der

                Important

                Make sure to set the password of the key exactly the same as the password for the keystore!

                You need the program DERImport.class of course. Do some internet searches to find DERImport.java or DERImport.class and download it.

                If DERImport has become difficult to obtain, I can write a program to do the same thing-- just let me know.

                Non-CA-Signed Cert

                Run man keytool or see the Creating a Keystore section of JSSERefGuide.html.

                Automatic Server or WebServer startup on UNIX

                If you are on UNIX and want to automatically start and stop a Server or WebServer running with encryption, follow the instructions in the UNIX Quick Start chapter, and remember to make the init script configuration file readable only to root and to set the variables TLS_PASSWORD and TLS_KEYSTORE.

                If you are using a private server certificate, make sure to also set the trust store filepath as shown in the sample init script configuration file.

                The cautionary warning above still applies. The password will be visible to any minimally competent local UNIX user who wants to see it.

                Purpose, Coverage, Changes in Behavior

                This document explains how to use SqlTool, the main purpose of which is to read your SQL text file or stdin, and execute the SQL commands therein against a JDBC database. There are also a great number of features to facilitate both interactive use and automation. The following paragraphs explain in a general way why SqlTool is better than any existing tool for text-mode interactive SQL work, and for automated SQL tasks. Two important benefits which SqlTool shares with other pure Java JDBC tools is that users can use a consistent interface and syntax to interact with a huge variety of databases-- any database which supports JDBC; plus the tool itself runs on any Java platform. Instead of using isql for Sybase, psql for Postgresql, Sql*plus for Oracle, etc., you can use SqlTool for all of them. As far as I know, SqlTool is the only production-ready, pure Java, command-line, generic JDBC client. Several databases come with a command-line client with limited JDBC abilities (usually designed for use with their specific database).

                SqlTool is purposefully not a Gui tool like Toad or DatabaseManager. There are many use cases where a Gui SQL tool would be better. Where automation is involved in any way, you really need a text client to at least test things properly and usually to prototype and try things out. A command-line tool is really better for executing SQL scripts, any form of automation, direct-to-file fetching, and remote client usage. To clarify this last, if you have to do your SQL client work on a work server on the other side of a VPN connection, you will quickly appreciate the speed difference between text data transmission and graphical data transmission, even if using VNC or Remote Console. Another case would be where you are doing some repetitive or very structured work where variables or language features would be useful. Gui proponents may disagree with me, but scripting (of any sort) is more efficient than repetitive copy & pasting with a Gui editor. SqlTool starts up very quickly, and it takes up a tiny fraction of the RAM required to run a comparably complex Gui like Toad.

                SqlTool is superior for interactive use because over many years it has evolved lots of features proven to be efficient for day-to-day use. Three concise help commands (\?, :?, and *?) list all available commands of the corresponding type. SqlTool doesn't support up-arrow or other OOB escapes (due to basic Java I/O limitations), but it more than makes up for this limitation with aliases, user variables, command-line history and recall, and command-line editing with extended Perl/Java regular expressions. The \d commands deliver JDBC metadata information as consistently as possible (in several cases, database-specific work-arounds are used to obtain the underlying data even though the database doesn't provide metadata according to the JDBC specs). Unlike server-side language features, the same feature set works for any database server. Database access details may be supplied on the command line, but day-to-day users will want to centralize JDBC connection details into a single, protected RC file. You can put connection details (username, password, URL, and other optional settings) for scores of target databases into your RC file, then connect to any of them whenever you want by just giving SqlTool the ID ("urlid") for that database. When you Execute SqlTool interactively, it behaves by default exactly as you would want it to. If errors occur, you are given specific error messages and you can decide whether to roll back your session. You can easily change this behavior to auto-commit, exit-upon-error, etc., for the current session or for all interactive invocations. You can import or export delimiter-separated-value files.

                When you Execute SqlTool with a SQL script, it behaves by default exactly as you would want it to. If any error is encountered, the connection will be rolled back, then SqlTool will exit with an error exit value. If you wish, you can detect and handle error (or other) conditions yourself. For scripts expected to produce errors (like many scripts provided by database vendors), you can have SqlTool continue-upon-error. For SQL script-writers, you will have access to portable scripting features which you've had to live without until now. You can use variables set on the command line or in your script. You can handle specific errors based on the output of SQL commands or of your variables. You can chain SQL scripts, invoke external programs, dump data to files, use prepared statements, Finally, you have a procedural language with if, foreach, while, continue, and break statements.

                Platforms and SqlTool versions covered

                SqlTool runs on any Java 1.4 or later platform. I haven't run it with a non-Sun JVM in years (like Blackdown, IBM, JRockit, etc.), but I've had no reports of problems with them, and SqlTool uses none of the Sun-proprietary classes directly. Some of the examples below use quoting which works exactly as-is for any Bourne-compatible UNIX shell. (Only line-continuation would need to be changed for C-compatible UNIX shells). I have not yet tested these commands on Windows, and I doubt whether the quoting will work just like this (though it is possible). SqlTool is still a very useful tool even if you have no quoting capability at all.

                If you are using SqlTool from a HSQLDB distribution before version 1.8.0.8 final, you should use the documentation with that distribution, because this manual documents many new features, several significant changes to interactive-only commands, and a few changes effecting backwards-compatibility (see next section about that). This document is now updated for the current versions of SqlTool and SqlFile at the time I am writing this (versions 333 and 354 correspondingly, SqlFile is the class which does most of the work for SqlTool). Therefore, if you are using a version of SqlTool or SqlFile that is more than a couple revisions greater, you should find a newer version of this document. (The imprecision is due to content-independent revision increments at build time, and the likelihood of one or two behavior-independent bug fixes after public releases). The startup banner will report both versions when you run SqlTool interactively. (Dotted version numbers of SqlTool and SqlFile are older than 333 and 354).

                This guide covers SqlTool bundled with series 1.8 and 1.9 of HSQLDB. [1]

                Functional Changes

                This section lists changes to SqlTool since the last major release of HSQLDB which may effect the portability of SQL scripts. For this revision of this document, this list consists of script-impacting changes made to SqlTool after the final 1.8.0.0 HSQLDB release. I'm specifically not listing changes to interactive-only commands (":" commands, with one legacy exception which is listed below), since these commands can't be used in SQL scripts; and I'm specifically not listing backwards-compatible feature additions and enhancements. The reason for limiting the change list to only portability- impacting changes is that a list of all enhancements since just 1.8.0.0 would be pages long.

                • SqlTool now consistently outputs \r\n line breaks when on \r\n-linebreak platforms, like Windows. This includes output written to stdout, \w files, and \o files.
                • Time type values are always output with the date as well as the time. This was required in order to produce consistent output for the wildly varying formats provided by different database vendors.
                • DSV input now takes JDBC Timestamp format with date and optionally time of day.
                • The command ":;" is now strictly an interactive command. If you want to repeat a command in an SQL scripts, just repeat the exact text of the command. Non-interactive use now has no dependency on command history.
                • The command ":w" has replace the command \w. Unlike writing "output" to a file with \w, :w is used to write SQL "commands", and this is an interactive feature.
                • Shell scripts using raw mode (e.g. PL/SQL scripts) must terminate the raw code with a line containing ".;", which will also send the code to the database for execution. (The old "." command has been changed to ":." to make it very clear that the command is now an interactive command).
                • The --sql argument will never automatically append a semicolon to the text you provide. If you want to execute a command ending with a semi-- then type a semi.

                Although it doesn't effect scripts, I will mention a significant recent change to interactive commands. Special and PL commands are not stored to the edit buffer and to command history, so they can be recalled and edited just like SQL commands. Now, only edit/history : commands are not stored to the buffer and history.

                The Bare Minimum You Need to Know to Run SqlTool

                Warning

                If you are using an Oracle database server, it will commit your current transaction if you cleanly disconnect, regardless of whether you have set auto-commit or not. This will occur if you exit SqlTool (or any other client) in the normal way (as opposed to killing the process or using Ctrl-C, etc.). This is mentioned in this section only for brevity, so I don't need to mention it in the main text in the many places where auto-commit is discussed. This behavior has nothing to do with SqlTool. It is a quirk of Oracle.

                If you want to use SqlTool, then you either have an SQL text file, or you want to interactively type in SQL commands. If neither case applies to you, then you are looking at the wrong program.

                Procedure 8.1. To run SqlTool...

                1. Copy the file sqltool.rc from the directory sample [1] of your HSQLDB distribution to your home directory and secure access to it if your computer is accessible to anybody else (most likely from the network). This file will work as-is for a Memory Only database instance; or if your target is a HSQLDB Server running on your local computer with default settings and the password for the "sa" account is blank (the sa password is blank when new HSQLDB database instances are created). Edit the file if you need to change the target Server URL, username, password, character set, JDBC driver, or TLS trust store as documented in the RC File Authentication Setup section. (You could, alternatively, use the --inlineRc command-line switch to specify your connection parameters as documented in the Using Inline RC Authentication section).

                2. Find out where your hsqldb.jar file resides. It typically resides at HSQLDB_HOME/lib/hsqldb.jar where HSQLDB_HOME is the base directory of your HSQLDB software installation. For this reason, I'm going to use "$HSQLDB_HOME/lib/hsqldb.jar" as the path to hsqldb.jar for my examples, but understand that you need to use the actual path to your own hsqldb.jar file.

                3. Run 

                      java -jar $HSQLDB_HOME/lib/hsqldb.jar --help
                  to see what command-line arguments are available. Note that you don't need to worry about setting the CLASSPATH when you use the -jar switch to java. Assuming that you set up your SqlTool RC file at the default location and you want to use the HSQLDB JDBC driver, you will want to run something like 
                      java -jar $HSQLDB_HOME/lib/hsqldb.jar mem
                  for interactive use, or 
                      java -jar $HSQLDB_HOME/lib/hsqldb.jar --sql 'SQL statement;' mem
                  or 
                      java -jar $HSQLDB_HOME/lib/hsqldb.jar mem filepath1.sql...
                  where mem is an urlid, and the following arguments are paths to text SQL files. For the filepaths, you can use whatever wildcards your operating system shell supports.

                  The urlid mem in these commands is a key into your RC file, as explained in the RC File Authentication Setup section. Since this is a Memory Only database, you can use SqlTool with this urlid immediately with no database setup whatsoever (however, you can't persist any changes that you make to this database). The sample sqltool.rc file also defines the urlid "localhost-sa" for a local HSQLDB Server. At the end of this section, I explain how you can load some sample data to play with, if you want to.

                Important

                SqlTool does not commit SQL changes by default. This leaves it to the user's disgression whether to commit or rollback their modifications. Remember to either run \= to commit before quitting SqlTool (most databases also support the SQL command commit;, or use the --autoCommit command-line switch.

                If you put a file named auto.sql into your home directory, this file will be executed automatically every time that you run SqlTool interactively and without the --noAutoFile switch.

                To use a JDBC Driver other than the HSQLDB driver, you can't use the -jar switch because you need to modify the classpath. You must add the hsqldb.jar file and your JDBC driver classes to your classpath, and you must tell SqlTool what the JDBC driver class name is. The latter can be accomplished by either using the "--driver" switch, or setting "driver" in your config file. The RC File Authentication Setup section. explains the second method. Here's an example of the first method (after you have set the classpath appropriately). 

                java org.hsqldb.util.SqlTool --driver oracle.jdbc.OracleDriver urlid

                Tip

                If the tables of query output on your screen are all messy because of lines wrapping, the best and easiest solution is usually to resize your terminal emulator window to make it wider. (With some terms you click & drag the frame edges to resize, with others you use a menu system where you can enter the number of columns).

                If you are using SqlTool to connect to a HSQLDB network server or any non-HSQLDB database, you may prefer to use the jar file hsqltool.jar or hsqldbutil.jar instead of hsqldb.jar. These alternative jar files contain all of SqlTool without stuff you don't need, but you will have to follow a simple procedure to generate these jars. See the Using hsqltool.jar and hsqldbutil.jar section.

                Non-displayable Types

                There are many SQL types which SqlTool (being a text-based program) can't display properly. This includes the SQL types BLOB, JAVA_OBJECT, STRUCT, and OTHER. When you run a query that returns any of these, SqlTool will save the very first such value obtained to the binary buffer and will not display any output from this query. You can then save the binary value to a file, as explained in the Storing and retrieving binary files section.

                There are other types, such as BINARY, which JDBC can make displayable (by using ResultSet.getString()), but which you may very well want to retrieve in raw binary format. You can use the \b command to retrieve any-column-type-at-all in raw binary format (so you can later store the value to a binary file).

                Another restriction which all text-based database clients have is the practical inability for the user to type in binary data such as photos, audio streams, and serialized Java objects. You can use SqlTool to load any binary object into a database by telling SqlTool to get the insert/update datum from a file. This is also explained in the Storing and retrieving binary files section.

                Desktop shortcuts

                Desktop shortcuts and quick launch icons are useful, especially if you often run SqlTool with the same set of arguments. It's really easy to set up several of them-- one for each way that you invoke SqlTool (i.e., each one would start SqlTool with all the arguments for one of your typical startup needs). One typical setup is to have one shortcut for each database account which you normally use (use a different urlid argument in each shortcut's Target specification.

                Desktop icon setup varies depending on your Desktop manager, of course. I'll explain how to set up a SqlTool startup icon in Windows XP. Linux and Mac users should be able to take it from there, since it's easier with the common Linux and Mac desktops.

                Procedure 8.2. Creating a Desktop Shortcut for SqlTool

                1. Right click in the main Windows background.

                2. New

                3. Shortcut

                4. Browse

                5. Navigate to where your good JRE lives. For recent Sun JRE's, it installs to C:\Program Files\Java\*\bin by default (the * will be a JDK or JRE name and version number).

                6. Select java.exe.

                7. OK

                8. Next

                9. Enter any name

                10. Finish

                11. Right click the new icon.

                12. Properties

                13. Edit the Target field.

                14. Leave the path to java.exe exactly as it is, including the quotes, but append to what is there. Beginning with a space, enter the command-line that you want run.

                15. Change Icon... to a pretty icon.

                16. If you want a quick-launch icon instead of (or in addition to) a desktop shortcut icon, click and drag it to your quick launch bar. (You may or may not need to edit the Windows Toolbar properties to let you add new items).

                Loading sample data

                If you want some sample database objects and data to play with, execute the sampledata.sql SQL file. sampledata.sql resides in the sample directory of your HSQLDB distribution [1]. To separate the sample data from your regular data, you can put it into its own schema by running this before you import: 

                    CREATE SCHEMA sampledata AUTHORIZATION dba;
    SET SCHEMA sampledata;
                Run it like this from an SqlTool session 
                \i HSQLDB_HOME/sample/sampledata.sql
                where HSQLDB_HOME is the base directory of your HSQLDB software installation [1].

                For memory-only databases, you'll need to run this every time that you run SqlTool. For other (persistent) databases, the data will reside in your database until you drop the tables.

                RC File Authentication Setup

                RC file authentication setup is accomplished by creating a text RC configuration file. In this section, when I say configuration or config file, I mean an RC configuration file. RC files can be used by any JDBC client program that uses the org.hsqldb.util.RCData class-- this includes SqlTool, DatabaseManager, DatabaseManagerSwing. You can use it for your own JDBC client programs too.

                The following sample RC file resides at sample/sqltool.rc in your HSQLDB distribution [1].

                Example 8.1. Sample RC File

                # $Id: sqltool.rc,v 1.22 2007/08/09 03:22:21 unsaved Exp $

# This is a sample RC configuration file used by SqlTool, DatabaseManager,
# and any other program that uses the org.hsqldb.util.RCData class.

# You can run SqlTool right now by copying this file to your home directory
# and running
#    java -jar /path/to/hsqldb.jar mem
# This will access the first urlid definition below in order to use a 
# personal Memory-Only database.
# "url" values may, of course, contain JDBC connection properties, delimited
# with semicolons.

# If you have the least concerns about security, then secure access to
# your RC file.
# See the documentation for SqlTool for various ways to use this file.

# A personal Memory-Only (non-persistent) database.
urlid mem
url jdbc:hsqldb:mem:memdbid
username sa
password

# A personal, local, persistent database.
urlid personal
url jdbc:hsqldb:file:${user.home}/db/personal;shutdown=true
username sa
password
# When connecting directly to a file database like this, you should 
# use the shutdown connection property like this to shut down the DB
# properly when you exit the JVM.

# This is for a hsqldb Server running with default settings on your local
# computer (and for which you have not changed the password for "sa").
urlid localhost-sa

# Template for a urlid for an Oracle database.
# You will need to put the oracle.jdbc.OracleDriver class into your 
# classpath.
# In the great majority of cases, you want to use the file classes12.zip
# (which you can get from the directory $ORACLE_HOME/jdbc/lib of any
# Oracle installation compatible with your server).
# Since you need to add to the classpath, you can't invoke SqlTool with
# the jar switch, like "java -jar .../hsqldb.jar..." or 
# "java -jar .../hsqlsqltool.jar...".
# Put both the HSQLDB jar and classes12.zip in your classpath (and export!)
# and run something like "java org.hsqldb.util.SqlTool...".

# Template for a TLS-encrypted HSQLDB Server.
# Remember that the hostname in hsqls (and https) JDBC URLs must match the
# CN of the server certificate (the port and instance alias that follows 
# are not part of the certificate at all).
# You only need to set "truststore" if the server cert is not approved by
# your system default truststore (which a commercial certificate probably
# would be).

# Note that "databases" in SQL Server and Sybase are traditionally used for
# the same purpose as "schemas" with more SQL-compliant databases.

# Template for a Microsoft SQL Server database
#urlid msprojsvr
#url jdbc:microsoft:sqlserver://hostname;DatabaseName=DbName;SelectMethod=Cursor
# The SelectMethod setting is required to do more than one thing on a JDBC
# session (I guess Microsoft thought nobody would really use Java for 
# anything other than a "hello world" program).
# This is for Microsoft's SQL Server 2000 driver (requires mssqlserver.jar
# and msutil.jar).
#driver com.microsoft.jdbc.sqlserver.SQLServerDriver
#username myuser

# Template for a Sybase database
#urlid sybase
#url jdbc:sybase:Tds:hostname:4100/dbname
#username blaine
#password hiddenpwd
# This is for the jConnect driver (requires jconn3.jar).
#driver com.sybase.jdbc3.jdbc.SybDriver

# Template for Embedded Derby / Java DB.
#urlid derby1
#url jdbc:derby:path/to/derby/directory;create=true
#username ${user.name}
#password any_noauthbydefault
#driver org.apache.derby.jdbc.EmbeddedDriver
# The embedded Derby driver requires derby.jar.
# There'a also the org.apache.derby.jdbc.ClientDriver driver with URL
# like jdbc:derby://<server>[:<port>]/databaseName, which requires
# derbyclient.jar.
# You can use \= to commit, since the Derby team decided (why???)
# not to implement the SQL standard statement "commit"!!
# Note that SqlTool can not shut down an embedded Derby database properly,
# since that requires an additional SQL connection just for that purpose.
# However, I've never lost data by not shutting it down properly.
# Other than not supporting this quirk of Derby, SqlTool is miles ahead of ij.

                You can put this file anywhere you want to, and specify the location to SqlTool/DatabaseManager/DatabaseManagerSwing by using the --rcfile argument. If there is no reason to not use the default location (and there are situations where you would not want to), then use the default location and you won't have to give --rcfile arguments to SqlTool/DatabaseManager/DatabaseManagerSwing. The default location is sqltool.rc or dbmanager.rc in your home directory (corresponding to the program using it). If you have any doubt about where your home directory is, just run SqlTool with a phony urlid and it will tell you where it expects the configuration file to be. 

                    java -jar $HSQLDB_HOME/lib/hsqldb.jar x

                The config file consists of stanza(s) like this: 

                    urlid web
    url jdbc:hsqldb:hsql://localhost
    username web
    password webspassword

                These four settings are required for every urlid. (There are optional settings also, which are described a couple paragraphs down). The URL may contain JDBC connection properties. You can have as many blank lines and comments like 

                    # This comment

                in the file as you like. The whole point is that the urlid that you give in your SqlTool/DatabaseManager command must match a urlid in your configuration file.

                Important

                Use whatever facilities are at your disposal to protect your configuration file.

                It should be readable, both locally and remotely, only to users who run programs that need it. On UNIX, this is easily accomplished by using chmod/chown commands and making sure that it is protected from anonymous remote access (like via NFS, FTP or Samba).

                You can also put the following optional settings into a urlid stanza. The setting will, of course, only apply to that urlid.

                charset
                This is used by the SqlTool program, but not by the DatabaseManager programs. See the Character Encoding section of the Non-Interactive section. You can, alternatively, set this for one SqlTool invocation by setting the system property sqlfile.charset . Defaults to US-ASCII.
                driver
                Sets the JDBC driver class name. You can, alternatively, set this for one SqlTool/DatabaseManager invocation by using the command line switch --driver. Defaults to org.hsqldb.jdbcDriver.
                truststore
                TLS trust keystore store file path as documented in the TLS chapter. You usually only need to set this if the server is using a non-publicly-certified certificate (like a self-signed self-ca'd cert).

                Property and SqlTool command-line switches override settings made in the configuration file.

                Using Inline RC Authentication

                Inline RC authentication setup is accomplished by using the --inlineRc command-line switch on SqlTool. The --inlineRc command-line switch takes a comma-separated list of key/value elements. The url and user elements are required. The rest are optional.

                url
                The JDBC URL of the database you wish to connect to.
                user
                The username to connect to the database as.
                charset
                Sets the character encoding. Defaults to US-ASCII.
                trust
                The TLS trust keystore file path as documented in the TLS chapter.
                password
                You may only use this element to set empty password, like 
                                    password=
                . For any other password value, omit the password element and you will be prompted for the value.

                (Use the --driver switch instead of --inlineRc to specify a JDBC driver class). Here is an example of invoking SqlTool to connect to a standalone database. 

                    java -jar $HSQLDB_HOME/lib/hsqldb.jar
         --inlineRc URL=jdbc:hsqldb:file:/home/dan/dandb,USER=dan

                For security reasons, you cannot specify a non-empty password as an argument. You will be prompted for a password as part of the login process.

                Using the current version of SqlTool with an older HSQLDB distribution.

                This procedure will allow users of a legacy version of HSQLDB to use all of the new features of SqlTool. You will also get the new versions of the DatabaseManagers! This procedure works for distros going back to 1.7.3.3 at least, probably much farther.

                Follow the instructions in the See the Using hsqltool.jar and hsqldbutil.jar section to build the jar file hsqldbutil.jar.

                For now on, whenever you are going to run SqlTool, make sure that you have this hsqldbutil.jar as the first item in your CLASSPATH. You can't run SqlTool with the "-jar" switch (because the -jar switch doesn't permit setting your own class path).

                Here's a UNIX example where somebody wants to use the new SqlTool with their older HSQLDB database, as well as with Postgresql and a local application. 

                CLASSPATH=/path/to/hsqldbutil.jar:/home/bob/classes:/usr/local/lib/pg.jdbc3.jar
export CLASSPATH
java org.hsqldb.util.SqlTool urlid

                Interactive Usage

                Do read the The Bare Minimum section before you read this section.

                You run SqlTool interactively by specifying no SQL filepaths on the SqlTool command line. Like this. 

                    java -jar $HSQLDB_HOME/lib/hsqldb.jar urlid

                Procedure 8.3. What happens when SqlTool is run interactively (using all default settings)

                1. SqlTool starts up and connects to the specified database, using your SqlTool configuration file (as explained in the RC File Authentication Setup section).

                2. SQL file auto.sql in your home directory is executed (if there is one),

                3. SqlTool displays a banner showing the SqlTool and SqlFile version numbers and describes the different command types that you can give, as well as commands to list all of the specific commands available to you.

                You exit your session by using the "\q" special command or ending input (like with Ctrl-D or Ctrl-Z).

                Important

                Every command (regardless of type) and comment must begin at the beginning of a line (or immediately after a comment ends with "*/").

                You can't nest commands or comments. You can only start new commands (and comments) after the preceding statement has been terminated. (Remember that if you're running SqlTool interactively, you can terminate an SQL statement without executing it by entering a blank line).

                (Special Commands, Edit Buffer Commands and PL Commands always consist of just one line. Any of these commands or comments may be preceded by space characters.)

                These rules do not apply at all to Raw Mode. Raw mode is for use by advanced users when they want to completely bypass SqlTool processing in order to enter a chunk of text for direct transmission to the database engine.

                Command Types

                When you are typing into SqlTool, you are always typing part of the immediate command. You execute the immediate command by hitting ENTER after a semi-colon (for SQL commands) or by just hitting ENTER (after any other non-empty command-- see next section about this distinction). The interactive : commands can perform actions with or on the edit buffer. The edit buffer usually contains a copy of the last command executed, and you can always view it with the :b command. If you never use any : commands, you can entirely ignore the edit buffer. If you want to repeat commands or edit previous commands, you will need to work with the edit buffer. The immediate command contains whatever (and exactly what) you type. The command history and edit buffer may contain any type of command other than comments and : commands (i.e., : commands and comments are just not copied to the history or to the edit buffer).

                Hopefully an example will clarify the difference between the immediate command and the edit buffer. If you type in the edit buffer Substitution command ":s/tbl/table/", the :s command that you typed is the immediate command (and it will never be stored to the edit buffer or history, since it is a : command), but the purpose of the substitution command is to modify the contents of the edit buffer (perform a substitution on it)-- the goal being that after your substitutions you would execute the buffer with the ":;" command. The ":a" command is special in that when you hit ENTER to execute it, it copies the contents of the edit buffer to a new immediate command and leaves you in a state where you are appending to that immediate command (nearly) exactly as if you had just typed it in.

                Command Types

                Command types

                Note

                Above, we said that if you enter an SQL command, one SQL command corresponds to one SqlTool command. This is the most typical usage, however, you can actually put multiple SQL statements into one SQL command. One example would be 

                    INSERT INTO t1 VALUES(0); SELECT * FROM t1;
                This is one SqlTool command containing two SQL statements. See the Chunking section to see why you may want to chunk SQL commands, how, and the implications.

                SQL Statement

                Any command that you enter which does not begin with "\", ":", or "* " is an SQL Statement. The command is not terminated when you hit ENTER, like most OS shells. You terminate SQL Statements with either ";" at the end of a line, or with a blank line. In the former case, the SQL Statement will be executed against the SQL database and the command will go into the edit buffer and SQL command history for editing or viewing later on. In the former case, execute against the SQL database means to transmit the SQL text to the database engine for execution. In the latter case (you end an SQL Statement with a blank line), the command will go to the edit buffer and SQL history, but will not be executed (but you can execute it later from the edit buffer). (See the note immediately above about multiple SQL statements in one SqlTool command).

                (Blank lines are only interpreted this way when SqlTool is run interactively. In SQL files, blank lines inside of SQL statements remain part of the SQL statement).

                As a result of these termination rules, whenever you are entering text that is not a Special Command, Edit Buffer / History Command, or PL Command, you are always appending lines to an SQL Statement or comment. (In the case of the first line, you will be appending to an empty SQL statement. I.e. you will be starting a new SQL Statement or comment).

                Special Command
                Run the command "\?" to list the Special Commands. All of the Special Commands begin with "\". I'll describe some of the most useful Special Commands below.
                Edit Buffer / History Command
                Run the command ":?" to list the Edit-Buffer/History Commands. All of these commands begin with ":". These commands use commands from the command history, or operate upon the edit "buffer", so that you can edit and/or (re-)execute previously entered commands.
                PL Command

                Procedural Langage commands. Run the command "*?" to list the PL Commands. All of the PL Commands begin with "*". PL commands are for setting and using scripting variables and conditional and flow control statements like * if and * while. A few PL features (such as PL aliases and updating and selecing data directly from/to files) can be a real convenience for nearly all users, so these features will be discussed briefly in this section. More detailed explanation of PL variables and the other PL features, with examples, are covered in the SqlTool Procedural Language section.

                Raw Mode
                The descriptions of command-types above do not apply to Raw Mode. In raw mode, SqlTool doesn't interpret what you type at all. It all just goes into the edit buffer which you can send to the database engine. Beginners can safely ignore raw mode. You will never encounter it unless you run the "\." special command, or enter a PL/SQL command. See the Raw Mode section for the details.

                Special Commands

                Essential Special Commands

                \?
                help
                \q
                quit
                \i path/to/script.sql
                execute the specified SQL script, then continue again interactively.
                \=
                commit the current SQL transaction. Most users are used to typing the SQL statement commit;, but this command is crucial for those databases which don't support the statement. It's obviously unnecessary if you have auto-commit mode on.
                \x?
                List a summary of DSV eXporting, and all available DSV options.
                \m?
                List a summary of DSV iMporting, and all available DSV options.
                \d?
                List a summary of the \d commands below.
                \dt [filter_substring]
                \dv [filter_substring]
                \ds [filter_substring]
                \di [table_name]
                \dS [filter_substring]
                \da [filter_substring]
                \dn [filter_substring]
                \du [filter_substring]
                \dr [filter_substring]
                \d* [filter_substring]

                Lists available objects of the given type.

                • t: non-system Tables
                • v: Views
                • s: Sequences
                • i: Indexes
                • S: System tables
                • a: Aliases
                • n: schema Names
                • u: database Users
                • r: Roles
                • *: all table-like objects
                If your database supports schemas, then the schema name will also be listed.

                If you supply an optional filter substring, then only items which contain the given substring (in the object name or schema name) will be listed.

                Important

                The substring test is case-sensitive! Even though in SQL queries and for the "\d objectname" command object names are usually case-insensitive, for the \dX commands, you must capitalize the filter substring exactly as it will appear in the special command output. This is an inconvenience, since the database engine will change names in SQL to default case unless you double-quote the name, but that is server-side functionality which cannot (portably) be reproduced by SqlTool. You can use spaces and other special characters in the string.

                Tip

                Filter substrings ending with "." are special. If a substring ends with ".", then this means to narrow the search by the exact, case-sensitive schema name given. For example, if I run "\d* BLAINE.", this will list all table-like database objects in the "BLAINE" schema. The capitalization of the schema must be exactly the same as how the schema name is listed by the "\dn" command. You can use spaces and other special characters in the string. (I.e., enter the name exactly how you would enter it inside of double-quotes in an SQL command). This is an inconvenience, since the database engine will change names in SQL to default case unless you double-quote the name, but that is server-side functionality which cannot (portably) be reproduced by SqlTool.

                Important

                Indexes may not be searched for by substring, only by exact target table name. So if I1 is an index on table T1, then you list this index by running "\di T1". In addition, many database vendors will report on indexes only if a target table is identified. Therefore, "\di" with no argument will fail if your database vendor does not support it.

                \d objectname [filter]

                Lists names of columns in the specified table or view. objectname may be a base table name or a schema.object name.

                If you supply a filter string, then only columns with a name containing the given filter will be listed. The objectname is nearly always case-insensitive (depends on your database), but the filter is always case-sensitive. You'll find this filter is a great convenience compared to other database utilities, where you have to list all columns of large tables when you are only interested in one of them.

                Tip

                When working with real data (as opposed to learning or playing), I often find it useful to run two SqlTool sessions in two side-by-side terminal emulator windows. I do all of my real work in one window, and use the other mostly for \d commands. This way I can refer to the data dictionary while writing SQL commands, without having to scroll.

                This list here includes only the essential Special Commands, but n.b. that there are other useful Special Commands which you can list by running \?. (You can, for example, execute SQL from external SQL files, and save your interactive SQL commands to files). Some specifics of these other commands are specified immediately below, and the Generating Text or HTML Reports section explains how to use the "\o" and "\H" special commands to generate reports.

                Be aware that the \! Special Command does not work for external programs that read from standard input. You can invoke non-interactive and graphical interactive programs, but not command-line interactive programs.

                SqlTool executes \! programs directly, it does not run an operating system shell (this is to avoid OS-specific code in SqlTool). Because of this, you can give as many command-line arguments as you wish, but you can't use shell wildcards or redirection.

                The \w command can be used to store any command in your SQL history to a file. Just restore the command to the edit buffer with a command like "\-4" before you give the \w command.

                Edit Buffer / History Commands

                Edit Buffer / History Commands

                :?
                help
                :b
                List the current contents of the edit buffer.
                :h
                Shows the Command History. For each command which has been executed (up to the max history length), the SQL command history will show the command; its command number (#); and also how many commands back it is (as a negative number). : commands are never added to the history list. You can then use either form of the command identifier to recall a command to the edit buffer (the command described next) or as the target of any of the following : commands. This last is accomplished in a manner very similar to the vi editor. You specify the target command number between the colon and the command. As an example, if you gave the command :s/X/Y/, that would perform the substitution on the contents of the edit buffer; but if you gave the command :-3 s/X/Y/, that would perform the substitution on the command 3 back in the command history (and copy the output to the edit buffer). Also, just like vi, you can identify the command to recall by using a regular expression inside of slashes, like :/blue/ s/X/Y/ to operate on the last command you ran which contains "blue".
                :13 OR :-2 OR :/blue/

                Recalls a command from Command history to the edit buffer. Enter ":" followed by the positive command number from Command history, like ":13"... or ":" followed by a negative number like ":-2" for two commands back in the Command history... or ":" followed by a regular expression inside slashes, like ":/blue/" to recall the last command which contains "blue". The specified command will be written to the edit buffer so that you can execute it or edit it using the commands below.

                As described under the :h command immediately above, you can follow the command number here with any of the commands below to perform the given operation on the specified command from history instead of on the edit buffer contents. So, for example, ":4;" would load command 4 from history then execute it (see the ":;" command below).

                :;
                Executes the SQL, Special or PL statement in the edit buffer (by default). This is an extremely useful command. It's easy to remember because it consists of ":", meaning Edit Buffer Command, plus a line-terminating ";", (which generally means to execute an SQL statement, though in this case it will also execute a special or PL command).
                :a

                Enter append mode with the contents of the edit buffer (by default) as the current command. When you hit ENTER, things will be exactly as if you physically re-typed the command that is in the edit buffer. Whatever lines you type next will be appended to the immediate command. As always, you then have the choice of hitting ENTER to execute a Special or PL command, entering a blank line to store back to the edit buffer, or end a SQL statement with semi-colon and ENTER to execute it.

                You can, optionally, put a string after the :a, in which case things will be exactly as just described except the additional text will also be appended to the new immediate command. If you put a string after the :a which ends with ;, then the resultant new immediate command will just be executed right away, as if you typed in and entered the entire thing.

                If your edit buffer contains SELECT x FROM mytab and you run a:le, the resultant command will be SELECT x FROM mytable. If your edit buffer contains SELECT x FROM mytab and you run a: ORDER BY y, the resultant command will be SELECT x FROM mytab ORDER BY y. Notice that in the latter case the append text begins with a space character.

                :s/from regex/to string/switches

                The Substitution Command is the primary method for SqlTool command editing-- it operates upon the current edit buffer by default. The "to string" and the "switches" are both optional (though the final "/" is not). To start with, I'll discuss the use and behavior if you don't supply any substitution mode switches.

                Don't use "/" if it occurs in either "from string" or "to string". You can use any character that you want in place of "/", but it must not occur in the from or to strings. Example 

                    :s@from string@to string@

                The to string is substituted for the first occurrence of the (case-specific) from string. The replacement will consider the entire SQL statement, even if it is a multi-line statement.

                In the example above, the from regex was a plain string, but it is interpreted as a regular expression so you can do all kinds of powerful substitutions. See the perlre man page, or the java.util.regex.Pattern API Spec for everything you need to know about extended regular expressions.

                Don't end a to string with ";" in attempt to make a command execute. There is a substitution mode switch to use for that purpose.

                You can use any combination of the substitution mode switches.

                • Use "i" to make the searches for from regex case insensitive.

                • Use "g" to substitute Globally, i.e., to subsitute all occurrences of the from regex instead of only the first occurrence found.

                • Use ";" to execute the command immediately after the substitution is performed.

                • Use "m" for ^ and $ to match each line-break in a multi-line edit buffer, instead of just at the very beginning and every end of the entire buffer.

                If you specify a command number (from the command history), you end up with a feature very reminiscent of vi, but even more powerful, since the Perl/Java regular expression are a superset of the vi regular expressions. As an example, 

                                    :24 s/pin/needle/g;
                would start with command number 24 from command history, substitute "needle" for all occurrences of "pin", then execute the result of that substitution (and this final statement will of course be copied to the edit buffer and to command history).

                :w /path/to/file.sql
                This appends the contents of the current buffer (by default) to the specified file. Since what is being written are Special, PL, or SQL commands, you are effectively creating an SQL script.

                I find the ":/regex/" and ":/regex/;" constructs particularly handy for every-day usage. 

                                    :/\\d/;
                re-executes the last \d command that you gave (The extra "\" is needed to escape the special meaning of "\" in regular expressions). It's great to be able to recall and execute the last "insert" command, for example, without needing to check the history or keep track of how many commands back it was. To re-execute the last insert command, just run ":/insert/;". If you want to be safe about it, do it in two steps to verify that you didn't accidentally recall some other command which happened to contain the string "insert", like 
                    :/insert/
    :;
                (Executing the last only if you are satisfied when SqlTool reports what command it restored). Often, of course, you will want to change the command before re-executing, and that's when you combine the :s and :a commands.

                We'll finish up with a couple fine points about Edit/Buffer commands. You generally can't use PL variables in Edit/Buffer commands, to eliminate possible ambiguities and complexities when modifying commands. The :w command is an exception to this rule, since it can be useful to use variables to determine the output file, and this command does not do any "editing".

                The :? help explains how you can change the default regular expression matching behavior (case sensitivity, etc.), but you can always use syntax like "(?i)" inside of your regular expression, as described in the Java API spec for class java.util.regex.Pattern, found here. History-command-matching with the /regex/ construct is purposefully liberal, matching any portion of the command, case sensitive, etc., but you can still use the method just described to modify this behavior. In this case, you could use "(?-i)" at the beginning of your regular expression to be case-sensitive.

                PL Commands

                Essential PL Command

                * VARNAME = value

                Set the value of a variable. If the variable doesn't exist yet, it will be created. The most common use for this is so that you can later use it in SQL statements, print statements, and PL conditionals, by using the *{VARNAME} or *{:VARNAME} construct. The only difference between *{VARNAME} and *{:VARNAME} is that the former produces an error if VARNAME is not set, whereas the latter will expand to a zero-length string if VARNAME is not set.

                If you set a variable to an SQL statement (without the terminating ";") you can then use it as a PL alias like /VARNAME, as shown in this example.

                Example 8.2. Defining and using a PL alias (PL variable)

                    * qry = SELECT COUNT(*) FROM mytable
    \p The stored query is '*{qry}'
    /qry;
    /qry WHERE mass > 200;

                If you put variable definitions into the SQL file auto.sql in your home directory, those aliases/variables will always be available for interactive use.

                PL variables can be expanded within all commands other than : edit/history commands.

                * load VARNAME /file/path.txt
                Sets VARNAME to the content of the specified ASCII file.
                * prepare VARNAME
                Indicate that next command should be a SQL INSERT or UPDATE command containing one question mark. The value of VARNAME will be substuted for the ? variable. This does work for CLOB columns.
                * VARNAME _
                When next SQL command is run, instead of displaying the rows, just store the very first column value to variable VARNAME. This works for CLOB columns too. It also works with Oracle XML type columns if you use column labels and the getclobval function.
                * VARNAME ~
                Exactly the same as 
                * VARNAME ~
                except that the fetched results will be displayed in addition to setting the variable.
                * dump VARNAME /file/path.txt
                Store the value of VARNAME to the specified ASCII file.

                ? Variable

                You don't set the ? variable. It is just like the Bourne shell variable ? in that it is always automatically set to the first value of a result set (or the return value of other SQL commands). It works just like the 

                * VARNAME ~
                command described above, but it all happens automatically. You can, of course, dereference ? like any PL variable, but it does not list with the 
                list
                and 
                listvalues
                commands. You can see the value whenever you want by running 
                    \p  *{?}

                Note that PL commands are used to upload and download column values to/from local ASCII files, but the corresponding actions for binary files use the special \b commands. This is because PL variables are used for ASCII values and you can store any number of column values in PL variables. This is not true for binary column values. The \b commands work with a single binary byte buffer.

                See the SqlTool Procedural Language section below for information on using variables in other ways, and information on the other PL commands and features.

                Storing and retrieving binary files

                You can upload binary files such as photographs, audio files, or serialized Java objects into database columns. SqlTool keeps one binary buffer which you can load from files with the \bl command, or from a database query by doing a one-row query for any non-displayable type (including BLOB, OBJECT, and OTHER). In the latter case, the data returned for the first non-displayable column of the first result row will be stored into the binary buffer.

                Once you have data in the binary buffer, you can upload it to a database column (including BLOB, OBJECT, and OTHER type columns), or save it to a file. The former is accomplished by the special command \bp followed by a prepared SQL query containing one question mark place-holder to indicate where the data gets inserted. The latter is accomplished with the \bd command.

                You can also store the output from normal, displayable column into the binary buffer by using the special command \b. The very first column value from the first result row of the next SQL command will be stored to the binary byte buffer.

                Example 8.3. Inserting binary data into database from a file

                    \bl /tmp/favoritesong.mp3
    \bp
    INSERT INTO musictbl (id, stream) VALUES(3112, ?);

                Example 8.4. Downloading binary data from database to a file

                    SELECT stream FROM musictbl WHERE id = 3112;
    \bd /tmp/favoritesong.mp3

                You can also store and retrieve text column values to/from ASCII files, as documented in the Essential PL Command section.

                Command History

                The SQL history shown by the \h command, and used by other commands, is truncated to 100 entries, since its utility comes from being able to quickly view the history list. You can change the history length by setting the system property sqltool.historyLength to an integer like 

                java -Dsqltool.historyLength=100 -jar $HSQLDB_HOME/lib/hsqldb.jar urlid
                If there is any demand, I'll make the setting of this value more convenient.

                The SQL history list contains all executed commands other than Edit Buffer commands and comments, even if the command has a syntax error or fails upon execution. The reason for including bad commands is so that you can recall and fix them if you wish to. The same applies to the edit buffer. If you copy a command to the edit buffer by entering blank line, or if you edit the edit buffer, that edit buffer value will never make it into the command history until and if you execute it.

                Shell scripting and command-line piping

                You normally use non-interactive mode for input piping. You specify "-" as the SQL file name. See the Piping and shell scripting subsection of the Non-Interactive chapter.

                Emulating Non-Interactive mode

                You can run SqlTool interactively, but have SqlTool behave exactly as if it were processing an SQL file (i.e., no command-line prompts, error-handling that defaults to fail-upon-error, etc.). Just specify "-" as the SQL file name in the command line. This is a good way to test what SqlTool will do when it encounters any specific command in an SQL file. See the Piping and shell scripting subsection of the Non-Interactive chapter for an example.

                Non-Interactive

                Read the Interactive Usage section if you have not already, because much of what is in this section builds upon that. You can skip all discussion about Command History and the edit buffer if you will not use those interactive features.

                Important

                If you're doing data updates, remember to issue a commit command or use the --autoCommit switch.

                As you'll see, SqlTool has many features that are very convenient for scripting. But what really makes it superior for automation tasks (as compared to SQL tools from other vendors) is the ability to reliably detect errors and to control JDBC transactions. SqlTool is designed so that you can reliably determine if errors occurred within SQL scripts themselves, and from the invoking environment (for example, from a perl, Bash, or Python script, or a simple cron tab invocation).

                Giving SQL on the Command Line

                If you just have a couple Commands to run, you can run them directly from the comand-line or from a shell script without an SQL file, like this. 

                    java -jar $HSQLDB_HOME/lib/hsqldb.jar --sql 'SQL statement;' urlid

                Note

                The --sql automatically implies --noinput, so if you want to execute the specified SQL before and in addition to an interactive session (or stdin piping), then you must also give the --stdinput switch.

                Since SqlTool transmits SQL statements to the database engine only when a line is terminated with ";", if you want feedback from multiple SQL statements in an --sql expression, you will need to use functionality of your OS shell to include linebreaks after the semicolons in the expression. With any Bourne-compatible shell, you can include linebreaks in the SQL statements like this. 

                    java -jar $HSQLDB_HOME/lib/hsqldb.jar --sql '
        SQL statement number one;
        SQL statement
            number two;
        SQL statement three;
    ' urlid
                If you don't need feedback, just separate the SQL commands with semicolons and the entire expression will be chunked.

                The --sql switch is very useful for setting shell variables to the output of SQL Statements, like this. 

                    # A shell script
    USERCOUNT=`java -jar $HSQLDB_HOME/lib/hsqldb.jar --sql '
        select count(*) from usertbl;
    ' urlid` || {
        # Handle the SqlTool error
    }
    echo "There are $USERCOUNT users registered in the database."
    [ "$USECOUNT" -gt 3 ] && {   # If there are more than 3 users registered
        # Some conditional shell scripting

                SQL Files

                Just give paths to sql text file(s) on the command line after the urlid.

                Often, you will want to redirect output to a file, like 

                java -jar $HSQLDB_HOME/lib/hsqldb.jar sql... > /tmp/log.sql 2>&1

                (Skip the "2>&1" if you're on Windows).

                You can also execute SQL files from an interactive session with the "\i"' Special Command, but be aware that the default behavior in an interactive session is to continue upon errors. If the SQL file was written without any concern for error handling, then the file will continue to execute after errors occur. You could run \c false before \i filename, but then your SqlTool session will exit if an error is encountered in the SQL file. If you have an SQL file without error handling, and you want to abort that file when an error occurs, but not exit SqlTool, the easiest way to accomplish this is usually to add \c false to the top of the script.

                If you specify multiple SQL files on the command-line, the default behavior is to exit SqlTool immediately if any of the SQL files encounters an error.

                SQL files themselves have ultimate control over error handling. Regardless of what command-line options are set, or what commands you give interactively, if a SQL file gives error handling statements, they will take precedence.

                You can also use \i in SQL files. This results in nested SQL files.

                You can use the following SQL file, sample.sql, which resides in the sample directory of your HSQLDB distribution [1]. It contains SQL as well as Special Commands making good use of most of the Special Commands documented below. 

                /*
    $Id: sample.sql,v 1.5 2005/05/02 15:07:27 unsaved Exp $
    Examplifies use of SqlTool.
    PCTASK Table creation
*/

/* Ignore error for these two statements */
\c true
DROP TABLE pctasklist;
DROP TABLE pctask;
\c false

\p Creating table pctask
CREATE TABLE pctask (
    id integer identity,
    name varchar(40),
    description varchar,
    url varchar,
    UNIQUE (name)
);

\p Creating table pctasklist
CREATE TABLE pctasklist (
    id integer identity,
    host varchar(20) not null,
    tasksequence int not null,
    pctask integer,
    assigndate timestamp default current_timestamp,
    completedate timestamp,
    show bit default true,
    FOREIGN KEY (pctask) REFERENCES pctask,
    UNIQUE (host, tasksequence)
);

\p Granting privileges
GRANT select ON pctask TO public;
GRANT all ON pctask TO tomcat;
GRANT select ON pctasklist TO public;
GRANT all ON pctasklist TO tomcat;

\p Inserting test records
INSERT INTO pctask (name, description, url) VALUES (
    'task one', 'Description for task 1', 'http://cnn.com');
INSERT INTO pctasklist (host, tasksequence, pctask) VALUES (
    'admc-masq', 101, SELECT id FROM pctask WHERE name = 'task one');

commit;

                You can execute this SQL file with a Memory Only database with a command like 

                    java -jar $HSQLDB_HOME/lib/hsqldb.jar  --sql '
        create user tomcat password "x";
    ' mem path/to/hsqldb/sample/sample.sql

                (The --sql "create...;" arguments create an account which the script uses). You should see error messages betwen the Continue-on-error...true and Continue-on-error...false. The script purposefully runs commands that might fail there. The reason the script does this is to perform database-independent conditional table removals. (The SQL clause IF EXISTS is more graceful and succinct, and should be used if you don't need to support databases which don't support IF EXISTS). If an error occurs when continue-on-error is false, the script would abort immedately.

                Piping and shell scripting

                You can of course, redirect output from SqlTool to a file or another program. 

                    java -jar $HSQLDB_HOME/lib/hsqldb.jar urlid file.sql > file.txt 2>&1

    java -jar $HSQLDB_HOME/lib/hsqldb.jar urlid file.sql 2>&1 | someprogram...

                You can type commands in to SqlTool while being in non-interactive mode by supplying "-" as the file name. This is a good way to test how SqlTool will behave when processing your SQL files. 

                        java -jar $HSQLDB_HOME/lib/hsqldb.jar urlid -

                This is how you have SqlTool read its input from another program:

                Example 8.5. Piping input into SqlTool

                        echo "Some SQL commands with '$VARIABLES';" |
        java -jar $HSQLDB_HOME/lib/hsqldb.jar urlid -

                Make sure that you also read the Giving SQL on the Command Line section. The --sql switch is a great facility to use with shell scripts.

                Optimally Compatible SQL Files

                If you want your SQL scripts optimally compatible among other SQL tools, then don't use any Special or PL Commands. SqlTool has default behavior which I think is far superior to the other SQL tools, but you will have to disable these defaults in order to have optimally compatible behavior.

                These switches provide compatibilty at the cost of poor control and error detection.

                • --continueOnErr

                  The output will still contain error messages about everything that SqlTool doesn't like (malformatted commands, SQL command failures, empty SQL commands), but SqlTool will continue to run. Errors will not cause rollbacks (but that won't matter because of the following setting).

                • --autoCommit

                You don't have to worry about accidental expansion of PL variables, since SqlTool will never expand PL variables if you don't set any variables on the command line, or give any "* " PL commands. (And you could not have "* " commands in a compatible SQL file).

                Comments

                SQL comments of the form /*...*/ must begin where a (SQL/Special/Edit-Buffer/PL) Command could begin, and they end with the very first "*/" (regardless of quotes, nesting, etc. You may have as many blank lines as you want inside of a comment.

                Example 8.6. Valid comment example

                    SELECT count(*) FROM atable;
    /* Lots of
     comments interspersed among
     several lines */   SELECT count(*)
    FROM btable;

                Notice that a command can start immediate after the comment ends.

                Example 8.7. Invalid comment example

                    SELECT count(*) FROM
    /* atable */
    btable;

                This comment is invalid because you could not start another command at the comment location (because it is within an SQL Statement).

                You can try using /*...*/ in other locations, and -- style SQL comments, but SqlTool will not treat them as comments. If they occur within an SQL Statment, SqlTool will pass them to the database engine, and the DB engine will determine whether to parse them as comments.

                Special Commands and Edit Buffer Commands in SQL Files

                Don't use Edit Buffer / History Commands in your sql files, because they won't work. Edit Buffer / History Commands are for interactive use only. (But, see the Raw Mode section for an exception). You can, of course, use any SqlTool command at all interactively. I just wanted to group together the commands most useful to script-writers.

                \q [abort message]

                Be aware that the \q command will cause SqlTool to completely exit. If a script x.sql has a \q command in it, then it doesn't matter if the script is executed like 

                    java -jar .../hsqldb.jar urlid a.sql x.sql z.sql
                or if you use \i to read it in interactively, or if another SQL file uses \i to nest it. If \q is encountered, SqlTool will quit. See the SqlTool Procedural Language section for commands to abort an SQL file (or even parts of an SQL file) without causing SqlTool to exit.

                \q takes an optional argument, which is an abort message. If you give an abort message, the message is displayed to the user and SqlTool will exit with a failure status. If you give no abort message, then SqlTool will exit quietly with successful status. As a result, 

                \q
                means to make an immediate but graceful exit, whereas 
                \q Message
                means to abort immediately.

                \p [text to print]
                Print the given string to stdout. Just give "\p" alone to print a blank line.
                \i /path/to/file.sql
                Include another SQL file at this location. You can use this to nest SQL files. For database installation scripts I often have a master SQL file which includes all of the other SQL files in the correct sequence. Be aware that the current continue-upon-error behavior will apply to included files until such point as the SQL file runs its own error handling commands.
                \o [file/path.txt]

                Tee output to the specified file (or stop doing so). See the Generating Text or HTML Reports section.

                \=
                A database-independent way to commit your SQL session.
                \a [true|false]
                This turns on and off SQL transaction autocommits. Auto-commit defaults to false, but you can change that behavior by using the --autoCommit command-line switch.
                \c [true|false]

                A "true" setting tells SqlTool to Continue when errors are encountered. The current transaction will not be rolled back upon SQL errors, so if \c is true, then run the ROLLCACK; command yourself if that's what you want to happen. The default for interactive use is to continue upon error, but the default for non-interactive use is to abort upon error. You can override this behavior by using the --continueOnErr or the --abortOnErr command-line switch.

                With database setup scripts, I usually find it convenient to set "true" before dropping tables (so that things will continue if the tables aren't there), then set it back to false so that real errors are caught. DROP TABLE tablename IF EXISTS; is a more elegant, but less portable, way to accomplish the same thing.

                Tip

                It depends on what you want your SQL files to do, of course, but I usually want my SQL files to abort when an error is encountered, without necessarily killing the SqlTool session. If this is the behavior that you want, then put an explicit \c false at the top of your SQL file and turn on continue-upon-error only for sections where you really want to permit errors, or where you are using PL commands to handle errors manually. This will give the desired behavior whether your script is called by somebody interactively, from the SqlTool command-line, or included in another SQL file (i.e. nested).

                Important

                The default settings are usually best for people who don't want to put in any explicit \c or error handling code at all. If you run SQL files from the SqlTool command line, then any errors will cause SqlTool to roll back and abort immediately. If you run SqlTool interactively and invoke SQL files with \i commands, the scripts will continue to run upon errors (and will not roll back). This behavior was chosen because there are lots of SQL files out there that produce errors which can be ignored; but we don't want to ignore errors that a user won't see. I reiterate that any and all of this behavior can (and often should) be changed by Special Commands run in your interactive shell or in the SQL files. Only you know whether errors in your SQL files can safely be ignored.

                Automation

                SqlTool is ideal for mission-critical automation because, unlike other SQL tools, SqlTool returns a dependable exit status and gives you control over error handling and SQL transactions. Autocommit is off by default, so you can build a completely dependable solution by intelligently using \c commands (Continue upon Errors) and commit statements, and by verifying exit statuses.

                Using the SqlTool Procedural Language, you have ultimate control over program flow, and you can use variables for database input and output as well as for many other purposes. See the SqlTool Procedural Language section.

                Getting Interactive Functionality with SQL Files

                Some script developers may run into cases where they want to run with sql files but they alwo want SqlTool's interactive behavior. For example, they may want to do command recall in the sql file, or they may want to log SqlTool's command-line prompts (which are not printed in non-interactive mode). In this case, do not give the sql file(s) as an argument to SqlTool, but pipe them in instead, like 

                java -jar $HSQLDB_HOME/lib/hsqldb.jar urlid < filepath1.sql > /tmp/log.html 2>&1
                or 
                cat filepath1.sql... |
java -jar $HSQLDB_HOME/lib/hsqldb.jar urlid > /tmp/log.html 2>&1

                Character Encoding

                SqlTool defaults to the US-ASCII character set (for reading). You can use another character set by setting the system property sqlfile.charset, like 

                java -Dsqlfile.charset=UTF-8 -jar $HSQLDB_HOME/lib/hsqldb.jar urlid file.sql...

                You can also set this per urlid in the SqlTool configuration file. See the RC File Authentication Setup section about that.

                Generating Text or HTML Reports

                This section is about making a file containing the output of database queries. You can generate reports by using operating system facilities such as redirection, tee, and cutting and pasting. But it is much easier to use the "\o" and "\H" special commands.

                Procedure 8.4. Writing query output to an external file

                1. By default, everthing will be done in plain text. If you want your report to be in HTML format, then give the special command \H. If you do so, you will probably want to use filenames with an suffix of ".html" or ".htm" instead of ".txt" in the next step.

                2. Run the command \o path/to/reportfile.txt. From this point on, output from your queries will be appended to the specified file. (I.e. another copy of the output is generated.) This way you can continue to monitor or use output as usual as the report is generated.

                3. When you want SqlTool to stop writing to the file, run \o (or just quit SqlTool if you have no other work to do).

                4. If you turned on HTML mode with \H before, you can run \H again to turn it back off, if you wish.

                It is not just the output of "SELECT" statements that will make it into the report file, but

                Kinds of output that get teed to \o files

                • Output of SELECT statements.
                • Output of all "\d" Special Commands. (I.e., "\dt", "\dv", etc., and "\d OBJECTNAME").
                • Output of "\p" Special Commands. You will want to use this to add titles, and perhaps spacing, for the output of individual queries.
                Other output will go to your screen or stdout, but will not make it into the report file. Be aware that no error messages will go into the report file. If SqlTool is run non-interactively (including if you give any SQL file(s) on the command line), SqlTool will abort with an error status if errors are encountered. The right way to handle errors is to check the SqlTool exit status. (The described error-handling behavior can be modified with SqlTool command-line switches and Special Commands).

                Warning

                Remember that \o appends to the named file. If you want a new file, then use a new file name or remove the pre-existing target file ahead of time.

                Tip

                So that I don't end up with a bunch of junk in my report file, I usually leave \o off while I perfect my SQL. With \o off, I perfect the SQL query until it produces on my screen exactly what I want saved to file. At this point I turn on \o and run ":;" to repeat the last SQL command. If I have several complex queries to run, I turn \o off and repeat until I'm finished. (Every time you turn \o on, it will append to the file, just like we need).

                Usually it doesn't come to mind that I need a wider screen until a query produces lines that are too long. In this case, stretch your window and repeat the last command with the ":;" Edit Buffer Command.

                SqlTool Procedural Language

                Aka PL

                Most importantly, run SqlTool interactively and give the "*?" command to see what PL commands are available to you. I've tried to design the language features to be intuitive. Readers experience with significant shell scripting in any language can probably learn everything they need to know by looking at (and running!) the sample script sample/pl.sql in your HSQLDB distribution [1] and using the *? command from within an interactive SqlTool session as a reference. (By significant shell scripting, I mean to the extent of using variables, for loops, etc.).

                PL variables will only be expanded after you run a PL command (or set variable(s) from the command-line). We only want to turn on variable expansion if the user wants variable expansion. People who don't use PL don't have to worry about strings getting accidentally expanded.

                All other PL commands imply the "*" command, so you only need to use the "*" statement if your script uses PL variables and it is possible that no variables may be set before-hand (and no PL commands have been run previously). In this case, without "*", your script would silently use a literal value like "*{x}" instead of trying to expand it. With a preceding "*" command, PL will notice that the variable x has not been set and will generate an error. (If x had been set here will be no issue because setting a variable automatically turns on PL variable expansion).

                PL is also used to upload and download column values to/from local ASCII files, analogously to the special \b commands for binary files. This is explained above in the Interactive Essential PL Command section above.

                Variables

                • Use the * list command to list some or all variables; or * listvalues to also see the values.
                • You can set variables using the * VARNAME = value command. This document explains elsewhere how you can set a values to the contents of files, and to the return value of SQL statements and fetches.
                • You can also set variables using the --setvar command-line switch. I give a very brief but useful example of this below.
                • Variables are always expanded in SQL, Special, and PL commands if they are written like *{VARNAME} (assuming that a PL command has been run previously). Your SQL scripts can give good feedback by echoing the value of variables with the "\p" special command. Use the construct *{:VARNAME} to expand the variable, but to expand to a zero-length string instead of fail if VARNAME is not set.

                • A variable written like /VARNAME is expanded if it begins an SQL Statement. This usage is called PL Aliasing. See the PL Aliases section below.

                • Variables are normally written like *VARNAME in logical expressions to prevent them from being evaluated too early. See below about logical expressions.

                • You can't do math with expression variables, but you can get functionality like the traditional for (i = 0; i < x; i++) by appending to a variable and testing the string length, like 

                      * while (*i < ${x})
        * i = *{i}.
                  i will be a growing line of dots.

                • Variable names must not contain white space, or the characters "}" or "=".

                PL Aliases

                PL Aliasing just means the use of a PL variable as the first thing in an SQL statement, with the shortcut notation /VARNAME.

                /VARNAME must be followed by whitespace or terminate the Statement, in order for SqlFile to tell where the variable name ends.

                Note

                Note that PL aliases are a very different thing from SQL aliases or HSQLDB aliases, which are features of databases, not SqlFile.

                If the value of a variable is an entire SQL command, you generally do not want to include the terminating ";" in the value. There is an example of this above.

                PL aliasing may only be used for SQL statements. You can define variables for everything in a Special or PL Command, except for the very first character ("\" or "*"). Therefore, you can use variables other than alias variables in Special and PL Commands. Here is a hyperbolically impractical example to show the extent to which PL variables can be used in Special commands even though you can not use them as PL aliases. 

                        sql> * qq = p Hello Butch
        sql> \*{qq} done now
        Hello Butch done now
                (Note that the \* here is not the special command "\*", but is the special command "\p" because "*{qq}" resolves to "p").

                Here is a short SQL file that gives the specified user write permissions on some application tables.

                Example 8.8. Simple SQL file using PL

                    /*
       grantwrite.sql

       Run SqlTool like this:
           java -jar path/to/hsqldb.jar -setvar USER=debbie grantwrite.sql
     */

    /* Explicitly turn on PL variable expansion, in case no variables have
       been set yet.  (Only the case if user did not set USER).
    */
    *

    GRANT all ON book TO *{USER};
    GRANT all ON category TO *{USER};

                Note that this script will work for any (existing) user just by supplying a different user name on the command-line. I.e., no need to modify the tested and proven script. There is no need for a commit statement in this SQL file since no DML is done. If the script is accidentally run without setting the USER variable, SqlTool will give a very clear notificaton of that.

                The purpose of the plain "*" command is just so that the *{USER} variables will be expanded. (This would not be necessary if the USER variable, or any other variable, were set, but we don't want to depend upon that).

                Logical Expressions

                Logical expressions occur only inside of logical expression parentheses in PL statements. For example, if (*var1 > astring) and while (*checkvar). (The parentheses after "foreach" do not enclose a logical expression, they just enclose a list).

                There is a critical difference between *{VARNAME} and *VARNAME inside logical expressions. *{VARNAME} is expanded one time when the parser first encounters the logical expression. *VARNAME is re-expanded every time that the expression is evaluated. So, you would never want to code * while (*{X} < 5) because the statement will always be true or always be false. (I.e. the following block will loop infinitely or will never run).

                Don't use quotes or whitespace of any kind in *{VARNAME} variables in expressions. (They would expand and then the expression would most likely no longer be a valid expression as listed in the table below). Quotes and whitespace are fine in *VARNAME variables, but it is the entire value that will be used in evaluations, regardless of whether quotes match up, etc. I.e. quotes and whitespace are not special to the token evaluator.

                Logical Operators

                TOKEN
                The token may be a literal, a *{VARNAME} which is expanded early, or a *VARNAME which is expanded late. (You usually do not want to use *{VARNAME} in logical expressions). False if the token is not set, empty, or "0". True otherwise.
                TOKEN1 == TOKEN2
                True if the two tokens are equivalent "strings".
                TOKEN1 <> TOKEN2
                Ditto.
                TOKEN1 >< TOKEN2
                Ditto.
                TOKEN1 > TOKEN2
                True if the TOKEN1 string is longer than TOKEN2 or is the same length but is greater according to a string sort.
                TOKEN1 < TOKEN2
                Similarly to TOKEN1 > TOKEN2.
                ! LOGICAL_EXPRESSION
                Logical negation of any of the expressions listed above.

                *VARNAMEs in logical expressions, where the VARNAME variable is not set, evaluate to an empty string. Therefore (*UNSETVAR = 0) would be false, even though (*UNSETVAR) by itself is false and (0) by itself is false. Another way of saying this is that *VARNAME in a logical expression is equivalent to *{:VARNAME} out of a logical expression.

                When developing scripts, you definitely use SqlTool interactively to verify that SqlTool evaluates logical expressions as you expect. Just run * if commands that print something (i.e. \p) if the test expression is true.

                Flow Control

                Flow control works by conditionally executing blocks of Commands according to conditions specified by logical expressions.

                The conditionally executed blocks are called PL Blocks. These PL Blocks always occur between a PL flow control statement (like * foreach, *while, * if) and a corresponding * end PL Command (like * end foreach).

                Caution

                Be aware that the PL block reader is ignorant about SQL statements and comments when looking for the end of the block. It just looks for lines beginning with some specific PL commands. Therefore, if you put a comment line before a PL statement, or if a line of a multi-line SQL statement has a line beginning with a PL command, things may break.

                I am not saying that you shouldn't use PL commands or SQL commands inside of PL blocks-- you definitely should! I'm saying that in PL blocks you should not have lines inside of SQL statments or comments which could be mistaken for PL commands. (Especially, "commenting out" PL end statements will not work if you leave * end at the beginning of the line).

                (This limitation will very likely be removed in a future version of SqlTool).

                The values of control variables for foreach and while PL blocks will change as expected.

                There are * break and * continue, which work as any shell scripter would expect them to. The * break command can also be used to quit the current SQL file without triggering any error processing. (I.e. processing will continue with the next line in the including SQL file or interactive session, or with the next SQL file if you supplied multiple on the command-line).

                Below is an example SQL File that shows how to use most PL features. If you have a question about how to use a particular PL feature, check this example before asking for help. This file resides in the sample directory with the name pl.sql [1]. Definitely give it a run, like 

                java -jar $HSQLDB_HOME/lib/hsqldb.jar mem $HSQLDB_HOME/pl.jar

                Chunking

                We hereby call the ability to transmit multiple SQL commands to the database in one transmission chunking. Unless you are in Raw mode, SqlTool only transmits commands to the database engine when it reads in a ";" at the end of a line of an SQL command. Therefore, you normally want to end each and every SQL command with ";" at the end of a line. This is because the database can only send one status reply to each JDBC transmission. So, while you could run 

                    SELECT * FROM t1; SELECT * FROM t2;
                SqlTool can only display the results from the last query. This is a limitation of the client/server nature of JDBC, and applies to any JDBC client. There are, however, situations where you don't need immediate feedback from every SQL command. For example,

                Example 8.10. Single-line chunking example

                    INSERT INTO t1 VALUES(0); SELECT * FROM t1;
                It's useful because the output of the second SQL command will tell you whether the first SQL command succeeded. So, you won't miss the status output from the first command.

                Why?

                The first general reason to chunk SQL commands is performance. For standalone databases, the most common performance bottleneck is network latency. Chunking SQL commands can dramatically reduce network traffic.

                The second general reason to chunk SQL commands is if your database requires you to send multiple commands in one transmission. This is often the case when you need to tell the database the SQL or PL/SQL commands that comprise a stored procedure, function, trigger, etc.

                How?

                The most simple way is enter as many SQL commands as you want, but just do not end a line with ";" until you want the chunk to transmit.

                Example 8.11. Multi-line chunking example

                    INSERT INTO t1 VALUES (1)
    ; INSERT INTO t1 VALUES (2)
    ; SELECT * FROM t1;
                If you list your command history with \s, you will see that all 3 SQL commands in 3 lines are in one SqlTool command. You can recall this SqlTool command from history to re-execute all three SQL commands.

                The other method is by using Raw Mode. Go to the Raw Mode section to see how. You can enter any text at all, exactly how you want it to be sent to the database engine. Therefore, in addition to chunking SQL commands, you can give commands for non-SQL extensions to the database. For example, you could enter JavaScript code to be used in a stored procedure.

                Raw Mode

                You begin raw mode by issuing the Special Command "\.". You can then enter as much text in any format you want. When you are finished, enter a line consisting of only ".;" to store the input to the edit buffer and send it to the database server for execution.

                This paragraph applies only to interactive usage. Interactive users may may end the raw input with ":." instead of ".;". This will just save the input to the edit buffer so that you can edit it and send it to the database manually. You can look at the edit buffer with the ":b" Buffer Command. You would normally use the command ":;" to send the buffer to the database after you are satisfied with it. You'll notice that your prompt will be the continuation prompt between entering "\." and terminating the raw input with ".;" or ":.".

                Example 8.12. Interactive Raw Mode example

                    sql> \.
    Enter RAW SQL.  No \, :, * commands.
    End with a line containing only ".;" to send to database,
    or ":." to store to edit buffer for editing or saving.
    -----------------------------------------------------------
    raw> line one;
      +> line two;
      +> line three;
      +> :.
    Raw SQL chunk moved into buffer.  Run ":;" to execute the chunk.

                The error message "Unexpected token: LINE in statement [line]" comes from the database engine, not SqlTool. All three lines were transmitted to the database engine.

                Edit Buffer Commands are not available when running SqlTool non-interactively.

                PL/SQL

                Note

                PL/SQL is not the same as PL. PL is the procedural language of SqlFile and is independent of your back-end database. PL commands always begin with *. PL/SQL is processed on the server side and you can only use it of your database supports it. You can not intermix PL and PL/SQL (except for setting a PL variable to the output of PL/SQL execution), because when you enter PL/SQL to SqlTool that input is not processed by SqlFile.

                Use Raw Mode to send PL/SQL code blocks to the database engine. You do not need to enter the "\." command to enter raw mode. Just begin a new SqlTool command line with "DECLARE" or "BEGIN", and SqlTool will automatically put you into raw mode. See the Raw Mode section for details.

                The following sample SQL file resides at sample/plsql.sql in your HSQLDB distribution [1]. This script will only work if your database engine supports standard PL/SQL, if you have permission to create the table "T1" in the default schema, and if that object does not already exist.

                Using hsqltool.jar and hsqldbutil.jar

                This section is for those users who want to use SqlTool but without the overhead of hsqldb.jar (or who want to use a new SqlTool build with an older HSQLDB distribution).

                If you do not need to directly use JDBC URLs like jdbc:hsqldb:mem: + something, jdbc:hsqldb:file: + something, or jdbc:hsqldb:res: + something, then you can use hsqltool.jar in place of the much larger hsqldb.jar file. hsqltool.jar will work for all JDBC databases other than HSQLDB Memory-only and In-process databases (the latter are fine if you access them via a HSQLB Server or WebServer). You will have to supply the JDBC driver for non-HSQLDB URLs, of course.

                hsqltool.jar includes the HSQLDB JDBC driver. If you do not need to connect to HSQLDB databases at all, then hsqldbutil.jar is what you want. hsqldbutil.jar contains everything you need to run SqlTool and DatabaseManagerSwing against non-HSQLDB databases... well, besides the JDBC drivers for the target databases.

                The HSQLDB distribution doesn't "come with" pre-built hsqltool.jar and hsqldbutil.jar files. You need to "build" them, but that is very easy to do.

                These instructions assume that you are capable of running an Ant build. See the Building HSQLDB chapter if you need more details than what you see here.

                1. Download and extract a current HSQLDB distribution. If you don't want to use the source code, documentation, etc., you can use a temporary directory and remove it afterwards.

                2. Cd to the build directory under the root directory where you extracted the distribution to.

                3. Run ant hsqldbutil or ant hsqltool according to the criteria above. (If your goal is to use this jar with an older HSQLDB distribution, then you definitely need to build hsqlbutil.jar).

                4. If you're going to clean up afterwards, copy the jar that you built out of lib to a safe location first.

                If you are using the HSQLDB JDBC driver (i.e., you're connecting up to a URL like jdbc:hsqldb:hsql + something or jdbc:hsqldb:http + something), you invoke SqlTool exactly as with hsqldb.jar except you use the file path to your new jar file instead of the path to hsqldb.jar.

                If you are using a non-HSQLDB JDBC driver, you must set your CLASSPATH to include this new jar file and your JDBC driver, then run SqlTool like 

                        java org.hsqldb.util.SqlTool ...
                You can specify your JDBC driver class either with the --driver switch to SqlTool, or in your RC file stanza (the last method is usually more convenient).

                Delimiter-Separated-Value Imports and Exports

                Note

                This feature is independent of HSQLDB Text Tables, a server-side feature of HSQLDB. It makes no difference to SqlTool whether the source or target table of your export/import is a memory, cache, or text table. Indeed, like all features of SqlTool, it works fine with other JDBC databases. It works great, for example to migrate data from a table of one type to a table of another type, or to another schema, or to another database instance, or to another database system.

                This feature is what most business people call "CSV", but these files are more accurately called Delimiter Separated Value files because the delimiter is usually not a comma, and, more importantly, we purposefully choose an effective delimiter instead of the CSV method of using a delimiter which works in some cases and then use quotes and back-slashes to escape occurrence of the delimiter in the actual data. Just by choosing a delimiter which never needs escaping, we eliminate the whole mess, and the data in our files always looks just like the corresponding data in the database. To make this CSV / Delimiter-separated-value dintinction clear, I use the suffix ".dsv" for my data files. This leads me to stipulate the abbreviation DSV for the Delimiter Separated Value feature of HSQLDB.

                Use the \x command to eXport a table to a DSV file, and the \m command to iMport a DSV file into a pre-existing table.

                The row and column delimiters may be any String, not just a single character. And just as the delimiter capability is more general than traditional CSV delimiters, the export function is also more general than just a table data exporter. Besides the trivial generalization that you may specify a view or other virtual table name in place of a table name, you can alternatively export the output of any query which produces normal text output. A benefit to this approach is that it allows you to export only some columns of a table, and to specify a WHERE clause to narrow down the rows to be exported (or perform any other SQL transformation, mapping, join, etc.). One specific use for this would be to exclude columns of binary data (which can be exported by other means, such as a PL loop to store binary values to files with the \bd command).

                Note that the import command will not create a new table. This is because of the impossibility of guessing appropriate types and constraints based only on column names and a data sampling (which is all that a DSV-importer has access to). Therefore, if you wish to populate a new table, create the table before running the import. The import file does not need to have data for all columns of a table. The only required columns are those required by database constraints (non-null, indexes, keys, etc.) One specific reason to omit columns is if you want values of some columns to be created automatically by column DEFAULT settings, triggers, HSQLDB identity sequences, etc. Another reason would be to skip binary columns.

                Simple DSV exports and imports using default settings

                Even if you need to change delimiters, table names, or file names from the defaults, I suggest that you run one export and import with default settings as a practice run. A memory-only HSQLDB instance is ideal for test runs like this.

                This command exports the table icf.projects to the file projects.dsv in the current directory (where you invoked SqlTool from). By default, the output file name will be the specified source table name plus the extension .dsv.

                Example 8.14. DSV Export Example

                    SET SCHEMA icf;
    \x projects
                We could also have run \x icf.projects (which would have created a file named icf.projects.dsv) instead of changing the session schema. In this example we have chosen to make the export file name independent of the schema to facilitate importing it into a different schema.

                Take a look at the output file. Notice that the first line consists of column names, not data. This line is present because it will be needed if the file is to used for a DSV import. Notice the following characterstics about the export data. The column delimiter is the pipe character "|". The record delimiter is the default line delimiter character(s) for your operating system. The string used to represent database NULLs is [null]. See the next section for how to change these from their default values.

                This command imports the data from the file projects.dsv in the current directory (where you invoked SqlTool from) into the table newschema.projects. By default, the output table name will be the input filename after removing optional leading directory and trailing final extension.

                Example 8.15. DSV Import Example

                    SET SCHEMA newschema;
    \m projects.dsv
                If the DSV file was named with the target schema, you would have skipped the SET SCHEMA command, like \m newschema.projects.dsv.

                Specifying queries and options

                For a hands on example of a DSM import which generates an import report and uses some other options, change to directory HSQLDB/sample and play with the working script dsv-sample.sql [1]. You can execute it like 

                    java -jar ../lib/hsqldb.jar mem dsv-sample.sql
                (assuming that you are using the supplied sqltool.rc file or have have urlid mem set up.

                The header line in the DSV file is required at this time. (If there is user demand, it can be made optional for exporting, but it will remain required for importing).

                Your export will fail if the column or record delimiter, or the null representation value occurs in the data being exported. You change these values by setting the PL variables *DSV_COL_DELIM, *DSV_ROW_DELIM, *DSV_NULL_REP. Notice that the asterisk is part of the variable names, to indicate that these variables are used by SqlTool internally. When specifying delimiters, you can use the escape seqpences \n, \r, \f, \t, \\, and decimal, octal or hex specifications like \20, \020, \0x20. For example, to change the column delimiter to the tab character, you would give the command 

                    * *DSV_COL_DELIM = \t

                For imports, you must always specify the source DSV file path. If you want to export to a different file than one in the current directory named according to the source table, set the PL variable *DSV_TARGET_FILE, like 

                    * *DSV_TARGET_FILE = /tmp/dtbl.dsv

                For exports, you must always specify the source table name or query. If you want to import to a table other than that derived from the input DSV file name, set the PL variable *DSV_TARGET_TABLE. The table name may contain a schema name prefix.

                You don't need to import all of the columns in a data file. To designate the fields to be skipped, iether set the PL PL variable *DSV_SKIP_COLUMNS, or replace the column names in the header line to "-" (hyphen). The value of *DSV_SKIP_COLUMNS is case-insensitive, and multiple column names are separated with white space and/or commas.

                You can specify a query instead of a tablename with the \x command in order to filter or transform data from a table or view, or to export the output of a join, etc. You must set the PL variable *DSV_TARGET_FILE, as explained above (since there is no table name from which to automatically map a file name).

                Example 8.16. DSV Export of an Arbitrary SELECT Statement

                    * *DSV_TARGET_FILE = outfile.txt
    \x SELECT entrydate, 2 * aval "Double aval", modtime FROM bs.dtbl
                Note that I specified the column label alias "Double aval" so that the label for that column in the DSV file header will not be blank.

                By default, imports will abort as soon as a error is encountered during parsing the file or inserting data. If you invoke SqlTool with a SQL script on the command line, the failure will cause SqlTool to roll back and exit. If run interactively, you can decide whether to commit or roll back the rows that inserted before the failure. You can modify this behavior with the \a and \c settings.

                If you set either a reject dsv file or a reject report file, then failures during imports will be reported but will not cause the import to abort. When run in this way, SqlTool will give you a report at the end about how many records were skipped, rejected, and successfully inserted. The reject dsv file is just a dsv file with exact copies of the dsv records that failed to insert. The reject report file is a HTML report which lists, for every rejected record, why that record was rejected.

                To allow for user-friendly entry of headers, we require that tables for DSV import/exports use standard column names. I.e., no column names that require quoting. The DSV import and export parsers are very smart and user-friendly. The data types of columns are checked so that the parser can make safe assumptions about white space and blank entries in the data. If a column is a JDBC Boolean type, for example, then we know that a field value of " True " obviously means "True", and that a field value of "" obviously means null. Since we require vanilla style column names, we allow white space anywhere in the header column. We allow blank lines anywhere (where "lines" are delimited by *DSV_ROW_DELIM). By default, commented lines are ignored, and the comment character can be changed from its default value.

                Run the command "\x?" or "\m?" to see the several system PL variables which you can set to adjust reject file behavior, commenting behavior, and other DSV features.

                You can also define some settings right in the DSV file, and you can even specify multiple header lines in a single DSV file. I use this last feature to import data from one data set into multple tables that are joined. Since I don't have any more time to dedicate to explaining all of these features, I'll give you some examples from working DSV files and let you take it from there.

                Example 8.17. Sample DSV headerswitch settings

                    # RCS keyword was here.

    headerswitch{
    itemdef:name|-|-|hardness|breakdc|-
    simpleitemdef:itemdef_name|maxvalue|weight|-|-|maxhp
    }
                I'll just note that the prefixes for the header rows must be of format target-table-name + :. You can use * for target-table-name here, for the obvious purpose.

                Example 8.18. DSV targettable setting

                    targettable=t
                This last example is from the SqlTool unit test file dsv-trimming.dsv. These special commands must be at the top of the file (before any normal data or header lines).

                There is also the *DSV_CONST_COLS setting, which you can use to automatically write static, constant values to the specified columns of all inserted rows.

                Unit Testing SqlTool

                The SqlTool unit tests reside at testrun/sqltool in the HSQLDB source code repository. Just run the runtests.bash script from that directory to execute all of the tests. Read the file README.txt to find out all about it, including everything you'd need to know to test your own scripts or to add more unit test scripts for SqlTool.


                [1] To reduce the time I will need to spend maintaining this document, in this chapter I am giving the path to the sample directory as it is in HSQLDB 1.9.x distributions, namely, HSQLDB_HOME/sample. HSQLDB 1.8.x users should translate these sample directory paths to use HSQLDB_HOME/src/org/hsqldb/sample/....

                HSQLDB version 1.8.0 supports the SQL statements and syntax described in this chapter.

                Notational Conventions Used in this Chapter

                [A] means A is optional.

                { B | C } means either B or C must be used.

                [{ B | C }] means either B or C may optionally be used, or nothing at all.

                ( and ) are the actual characters '(' and ')' used in statements.

                UPPERCASE words are keywords

                SQL Commands

                ALTER INDEX[2]

                ALTER INDEX <indexname> RENAME TO <newname>;

                Index names can be changed so long as they do not conflict with other user-defined or sytem-defined names.

                ALTER SEQUENCE[2]

                ALTER SEQUENCE <sequencename> RESTART WITH <value>;

                Resets the next value to be returned from the sequence.

                ALTER SCHEMA[2]

                ALTER SCHEMA <schemaname> RENAME TO <newname>;

                Renames the schema as specified. All objects of the schema will hereafter be accessible only with the new schema name.

                Requires Administrative privileges.

                ALTER TABLE[2]

                ALTER TABLE <tablename> ADD [COLUMN] <columnname> Datatype
    [(columnSize[,precision])] [{DEFAULT <defaultValue> |
    GENERATED BY DEFAULT AS IDENTITY (START WITH <n>[, INCREMENT BY <m>])}] |
    [[NOT] NULL] [IDENTITY] [PRIMARY KEY]
    [BEFORE <existingcolumn>];

                Adds the column to the end of the column list. The optional BEFORE <existingcolumn> can be used to specify the name of an existing column so that the new column is inserted in a position just before the <existingcolumn>.

                It accepts a columnDefinition as in a CREATE TABLE command. If NOT NULL is specified and the table is not empty, then a default value must be specified. In all other respects, this command is the equivalent of a column definition statement in a CREATE TABLE statement.

                If an SQL view includes a SELECT * FROM <tablename> in its select statement, the new column is added to the view. This is a non-standard feature which is likely to change in the future.

                ALTER TABLE <tablename> DROP [COLUMN] <columnname>;

                Drops the column from the table. Will drop any single-column primary key or unique constraint on the column as well. The command will not work if there is any multiple key constraint on the column or the column is referenced in a check constraint or a foreign key.

                It will also fail if an SQL view includes the column.

                ALTER TABLE <tablename> ALTER COLUMN <columnname> RENAME TO <newname>

                Changes a column name.

                ALTER TABLE <tablename> ALTER COLUMN <columnname> SET DEFAULT <defaultvalue>};

                Adds the specified default value to the column. Use NULL to remove a default.

                ALTER TABLE <tablename> ALTER COLUMN <columnname> SET [NOT] NULL

                Sets or removes a NOT NULL constraint for the column.

                ALTER TABLE <tablename> ALTER COLUMN <columnDefinition>;

                This form of ALTER TABLE ALTER COLUMN accepts a columnDefinition as in a CREATE TABLE command, with the following restrictions.

                Restrictions

                • The column must be already be a PK column to accept an IDENTITY definition.
                • If the column is already an IDENTITY column and there is no IDENTITY definition, the existing IDENTITY attribute is removed.
                • The default expression will be that of the new definition, meaning an existing default can be dropped by ommission, or a new default added.
                • The NOT NULL attribute will be that of the new definition (similar to previous item).
                • Depending on the type of change, the table may have to be empty for the command to work. It always works when the type of change is possible in general and the individual existing values can all be converted.
                ALTER TABLE <tablename> ALTER COLUMN <columnname>
    RESTART WITH <new sequence value>

                This form is used exclusively for IDENTITY columns and changes the next automatic value for the identity sequence.

                ALTER TABLE <tablename> ADD [CONSTRAINT <constraintname>]
    CHECK (<search condition>);

                Adds a check constraint to the table. In the current version, a check constraint can reference only the row being inserted or updated.

                ALTER TABLE <tablename> ADD [CONSTRAINT <constraintname>] UNIQUE (<column list>);

                Adds a unique constraint to the table. This will not work if there is already a unique constraint covering exactly the same <column list>.

                This will work only if the values of the column list for the existing rows are unique or include a null value.

                ALTER TABLE <tablename> ADD [CONSTRAINT <constraintname>]
    PRIMARY KEY (<column list>);

                Adds a primary key constraint to the table, using the same constraint syntax as when the primary key is specified in a table definition.

                ALTER TABLE <tablename>
    ADD [CONSTRAINT <constraintname>] FOREIGN KEY (<column list>)
    REFERENCES <exptablename> (<column list>)
    [ON {DELETE | UPDATE} {CASCADE | SET DEFAULT | SET NULL}];

                Adds a foreign key constraint to the table, using the same constraint syntax as when the foreign key is specified in a table definition.

                This will fail if for each existing row in the referring table, a matching row (with equal values for the column list) is not found in the referenced tables.

                ALTER TABLE <tablename> DROP CONSTRAINT <constraintname>;

                Drop a named unique, check or foreign key constraint from the table.

                ALTER TABLE <tablename> RENAME TO <newname>;

                ALTER USER[2]

                ALTER USER <username> SET PASSWORD <password>;

                Changes the password for an existing user. Password must be double quoted. Use "" for an empty password.

                DBA's may change users' base default schema name with the comand 

                ALTER USER <username> SET INITIAL SCHEMA <schemaname>;
                This is the schema which database object names will resolve to for this user, unless overridden as explained in Schema object naming. For reasons of backwards compatibility, the initial schema value will not be persisted across database shutdowns until HSQLDB version 1.8.1. (I.e., INITIAL SCHEMA settings will be lost upon database shutdown with HSQLDB versions lower than version 1.8.1).

                Only an administrator may use these commands.

                CALL

                CALL Expression;

                Any expression can be called like a stored procedure, including, but not only Java stored procedures or functions. This command returns a ResultSet with one column and one row (the result) just like a SELECT statement with one row and one column.

                See also: Stored Procedures / Functions, SQL Expression.

                CHECKPOINT

                CHECKPOINT [DEFRAG[2]];

                Closes the database files, rewrites the script file, deletes the log file and opens the database.

                If DEFRAG is specified, this command also shrinks the .data file to its minimal size.

                See also: SHUTDOWN, SET LOGSIZE.

                COMMIT

                COMMIT [WORK];

                Ends a transaction and makes the changes permanent.

                See also: ROLLBACK, SET AUTOCOMMIT, SET LOGSIZE.

                CONNECT

                CONNECT USER <username> PASSWORD <password>;

                Connects to the database as a different user. Password should be double quoted. Use "" for an empty password.

                See also: GRANT, REVOKE.

                CREATE ALIAS

                CREATE ALIAS <function> FOR <javaFunction>;

                Creates an alias for a static Java function to be used as a Stored Procedure. The function must be accessible from the JVM in which the database runs. Example:

                    CREATE ALIAS ABS FOR "java.lang.Math.abs";

                Note

                The CREATE ALIAS command just defines the alias. It does not validate existence of the target method or its containing class. To validate the alias, use it.

                See also: CALL, Stored Procedures / Functions.

                CREATE INDEX

                CREATE [UNIQUE] INDEX <index> ON <table> (<column> [DESC] [, ...]) [DESC];

                Creates an index on one or more columns in a table.

                Creating an index on searched columns may improve performance. The qualifier DESC can be present for command compatibility with other databases but it has no effect. Unique indexes can be defined but this is deprecated. Use UNIQUE constraints instead. The name of an index must be unique within the whole database.

                See also: CREATE TABLE, DROP INDEX.

                CREATE ROLE[2]

                CREATE ROLE <rolename>;

                Creates the named role with no members. Requires Administrative privileges.

                CREATE SCHEMA[2]

                CREATE SCHEMA <schemaname> AUTHORIZATION <grantee>
    [<createStatement> [<grantStatement>] [...];

                Creates the named schema, with ownership of the specified authorization. The authorization grantee may be a database user or a role.

                Optional (nested) CREATE and GRANT statements can be given only for new objects in this new schema. Only the last nested statement should be terminated with a semicolon, because the first semicolon encountered after "CREATE SCHEMA" will end the CREATE SCHEMA command. In the example below, a new schema, ACCOUNTS, is created, then two tables and a view are added to this schma and some rights on these objects are granted.

                    CREATE SCHEMA ACCOUNTS AUTHORIZATION DBA
        CREATE TABLE AB(A INTEGER, ...)
        CREATE TABLE CD(C CHAHR, ...)
        CREATE VIEW VI AS SELECT ...
        GRANT SELECT TO PUBLIC ON AB
        GRANT SELECT TO JOE ON CD;
                Note that this example consists of one CREATE SCHEMA statement which is terminated by a semicolon.

                Requires Administrative privileges.

                CREATE SEQUENCE[2]

                CREATE SEQUENCE <sequencename> [AS {INTEGER | BIGINT}]
    [START WITH <startvalue>] [INCREMENT BY <incrementvalue>];

                Creates a sequence. The default type is INTEGER. The default start value is 0 and the increment 1. Negative values are not allowed. If a sequence goes beyond Integer.MAXVALUE or Long.MAXVALUE, the next result is determined by 2's complement arithmetic.

                The next value for a sequence can be included in SELECT, INSERT and UPDATE statements as in the following example:

                SELECT [...,] NEXT VALUE FOR <sequencename> [, ...] FROM <tablename>;

                In the proposed SQL 200n and in the current version, there is no way of retreiving the last returned value of a sequence.

                CREATE TABLE

                CREATE [MEMORY | CACHED | [GLOBAL] TEMPORARY | TEMP [2] | TEXT[2]] TABLE <name>
    ( <columnDefinition> [, ...] [, <constraintDefinition>...] )
    [ON COMMIT {DELETE | PRESERVE} ROWS];

                Creates a tables in memory (default) or on disk and only cached in memory. If the database is all-in-memory, both MEMORY and CACHED forms of CREATE TABLE return a MEMORY table while the TEXT form is not allowed.

                Components of a CREATE TABLE command

                columnDefinition
                columnname Datatype [(columnSize[,precision])]
    [{DEFAULT <defaultValue> |
    GENERATED BY DEFAULT AS IDENTITY
    (START WITH <n>[, INCREMENT BY <m>])}] |
    [[NOT] NULL] [IDENTITY] [PRIMARY KEY]

                Default values that are allowed are constant values or certain SQL datetime functions.

                Allowed Default Values in Column Definitions

                • For character column, a single-quoted string or NULL. The only SQL function that can be used is CURRENT_USER.

                • For datetime columns, a single-quoted DATE, TIME or TIMESTAMP value or NULL. Or a datetime SQL function such as CURRENT_DATE, CURRENT_TIME, CURRENT_TIMESTAMP, TODAY, NOW. Each function is allowed for a certain datetime type.

                • For BOOLEAN columns, the literals FALSE, TRUE, NULL.

                • For numeric columns, any valid number or NULL.

                • For binary columns, any valid hex string or NULL.

                Only one identity column is allowed in each table. Identity columns are autoincrement columns. They must be of INTEGER or BIGINT type and are automatically primary key columns (as a result, multi-column primary keys are not possible with an IDENTITY column present). Using the long SQL syntax the (START WITH <n>) clause specifies the first value that will be used. The last inserted value into an identity column for a connection is available using the function IDENTITY(), for example (where Id is the identity column):

                INSERT INTO Test (Id, Name) VALUES (NULL,'Test');
    CALL IDENTITY();
                constraintDefinition
                [CONSTRAINT <name>]
    UNIQUE ( <column> [,<column>...] ) |
    PRIMARY KEY ( <column> [,<column>...] ) |
    FOREIGN KEY ( <column> [,<column>...] )
    REFERENCES <refTable> ( <column> [,<column>...]) 
    [ON {DELETE | UPDATE}
    {CASCADE | SET DEFAULT | SET NULL}][2] |
    CHECK(<search condition>)[2]

                Both ON DELETE and ON UPDATE clauses can be used in a single foreign key definition.

                search condition

                A search condition is similar to the set of conditions in a WHERE clause. In the current version of HSQLDB, the conditions for a CHECK constraint can only reference the current row, meaning there should be no SELECT statement. Sample table definitions with CHECK constraints are in TestSelfCheckConstraints.txt. This file is in the /hsqldb/testrun/hsqldb/ directory of the zip.

                General syntax limitations

                HSQLDB databases are initially created in a legacy mode that does not enforce column size and precision. You can set the property: sql.enforce_strict_size=true to enable this feature. When this property has been set, Any supplied column size and precision for numeric and character types (CHARACTER and VARCHAR) are enforced. Use the command, SET PROPERTY "sql.enforce_strict_size" TRUE once before defining the tables.

                NOT NULL constraints can be part of the column definition only. Other constraints cannot be part of the column definition and must appear at the end of the column definition list.

                TEMPORARY TABLE contents for each session (connection) are emptied by default at each commit or rollback. The optional qualifier ON COMMIT PRESERVE ROWS can be used to keep the rows while the session is open. The default is ON COMMIT DELETE ROWS.

                See also: DROP TABLE.

                CREATE TRIGGER[2]

                CREATE TRIGGER <name> {BEFORE | AFTER} {INSERT | UPDATE | DELETE} ON <table>
    [FOR EACH ROW] [QUEUE n] [NOWAIT] CALL <TriggerClass>;

                TriggerClass is an application-supplied class that implements the org.hsqldb.Trigger interface e.g. "mypackage.TrigClass". It is the fire method of this class that is invoked when the trigger event occurs. You should provide this class, which can have any name, and ensure that this TriggerClass is present in the classpath which you use to start hsqldb.

                Since 1.7.2 the implementation has been changed and enhanced. When the 'fire' method is called, it is passed the following arguments:

                    fire (String name, String table, Object row1[], Object row2[])

                where 'row1' and 'row2' represent the 'before' and 'after' states of the row acted on, with each column being a member of the array. The mapping of members of the row arrays to database types is specified in Data Types. For example, BIGINT is represented by a java.lang.Long Object. Note that the number of elements in the row arrays could be larger than the number of columns by one or two elements. Never modify the last elements of the array, which are not part of the actual row.

                If the trigger method wants to access the database, it must establish its own JDBC connection. This can cause data inconsistency and other problems so it is not recommended. The jdbc:default:connection: URL is not currently supported.

                Implementation note:

                If QUEUE 0 is specified, the fire method is execued in the same thread as the database engine. This allows trigger action to alter the data that is about to be stored in the database. Data can be checked or modified in BEFORE INSERT / UPDATE + FOR EACH ROW triggers. All table constraints are then enforced by the database engine and if there is a violation, the action is rejected for the SQL command that initiated the INSERT or UPDATE. There is an exception to this rule, that is with UPDATE queries, referential integrity and cascading actions resulting from ON UPDATE CASCASE / SET NULL / SET DEFAULT are all performed prior to the invocation of the trigger method. If an invalid value that breaks referential integrity is inserted in the row by the trigger method, this action is not checked and results in inconsistent data in the table.

                Alternatively, if the trigger is used for external communications and not for checking or altering the data, a queue size larger than zero can be specified. This is in the interests of not blocking the database's main thread as each trigger will run in a thread that will wait for its firing event to occur. When this happens, the trigger's thread calls TriggerClass.fire. There is a queue of events waiting to be run by each trigger thread. This is particularly useful for 'FOR EACH ROW' triggers, when a large number of trigger events occur in rapid succession, without the trigger thread getting a chance to run. If the queue becomes full, subsequent additions to it cause the database engine to suspend awaiting space in the queue. Take great care to avoid this situation if the trigger action involves accessing the database, as deadlock will occur. This can be avoided either by ensuring the QUEUE parameter makes a large enough queue, or by using the NOWAIT parameter, which causes a new trigger event to overwrite the most recent event in the queue. The default queue size is 1024. Note also that the timing of trigger method calls is not guaranteed, so applications should implement their own synchronization measures if necessary.

                With a non-zero QUEUE parameter, if the trigger methods modifies the 'row2' values, these changes may or may not affect the database and will almost certainly result in data inconsistency.

                Please refer to the code for org.hsqldb.sample.Trigger and org.hsqldb.sample.TriggerSample for more information on how to write a trigger class.

                CREATE USER

                CREATE USER <username> PASSWORD <password> [ADMIN];

                Creates a new user or new administrator in this database. Password must be double quoted. Empty password can be made using "". You can change a password afterwards using a ALTER USER[2] command.

                Only an administrator can do this.

                See also: CONNECT, GRANT, REVOKE. ALTER USER[2],

                CREATE VIEW[2]

                CREATE VIEW <viewname>[(<viewcolumn>,..) AS SELECT ... FROM ... [WHERE Expression]
[ORDER BY orderExpression [, ...]]
[LIMIT <limit> [OFFSET <offset>]];

                A view can be thought of as either a virtual table or a stored query. The data accessible through a view is not stored in the database as a distinct object. What is stored in the database is a SELECT statement. The result set of the SELECT statement forms the virtual table returned by the view. A user can use this virtual table by referencing the view name in SQL statements the same way a table is referenced. A view is used to do any or all of these functions:

                • Restrict a user to specific rows in a table. For example, allow an employee to see only the rows recording his or her work in a labor-tracking table.

                • Restrict a user to specific columns. For example, allow employees who do not work in payroll to see the name, office, work phone, and department columns in an employee table, but do not allow them to see any columns with salary information or personal information.

                • Join columns from multiple tables so that they look like a single table.

                • Aggregate information instead of supplying details. For example, present the sum of a column, or the maximum or minimum value from a column.

                Views are created by defining the SELECT statement that retrieves the data to be presented by the view. The data tables referenced by the SELECT statement are known as the base tables for the view. In this example, is a view that selects data from three base tables to present a virtual table of commonly needed data:

                    CREATE VIEW mealsjv AS
      SELECT m.mid mid, m.name name, t.mealtype mt, a.aid aid,
             a.gname + ' ' + a.sname author, m.description description,
             m.asof asof
        FROM meals m, mealtypes t, authors a
       WHERE m.mealtype = t.mealtype
        AND m.aid = a.aid;

                You can then reference mealsjv in statements in the same way you would reference a table:

                    SELECT * FROM mealsjv;

                A view can reference another view. For example, mealsjv presents information that is useful for long descriptions that contain identifiers, but a short list might be all a web page display needs. A view can be built that selects only specific mealsjv columns:

                    CREATE VIEW mealswebv AS SELECT name, author FROM mealsjv;

                The SELECT statement in a VIEW definition should return columns with distinct names. If the names of two columns in the SELECT statement are the same, use a column alias to distinguish between them. A list of new column names can always be defined for a view.

                    CREATE VIEW aview (new_name, new_author) AS
      SELECT name, author
      FROM mealsjv

                See also: SQL Expression, SELECT[2], DROP VIEW[2].

                DELETE

                DELETE FROM table [WHERE Expression];

                Removes rows in a table.

                See also: SQL Expression, INSERT, SELECT[2].

                DISCONNECT

                DISCONNECT;

                Closes this connection. It is not required to call this command when using the JDBC interface: it is called automatically when the connection is closed. After disconnecting, it is not possible to execute other queries (including CONNECT) with this connection.

                See also: CONNECT.

                DROP INDEX

                DROP INDEX index [IF EXISTS];

                Removes the specified index from the database. Will not work if the index backs a UNIQUE of FOREIGN KEY constraint.

                See also: CREATE INDEX.

                DROP ROLE[2]

                DROP ROLE <rolename>;

                Removes all members from specified role, then removes the role itself.

                DROP SEQUENCE[2]

                DROP SEQUENCE <sequencename> [IF EXISTS] [RESTRICT | CASCADE];

                Removes the specified sequence from the database. When IF EXIST is used, the statement returns without an error if the sequence does not exist. The RESTRICT option is in effect by default, meaning that DROP will fail if any view reference the sequence. Specify the CASCADE option to silently drop all dependent database objects.

                DROP SCHEMA[2]

                DROP SCHEMA <schemaname> [RESTRICT | CASCADE];

                Removes the specified schema from the database. The RESTRICT option is in effect by default, meaning that DROP will fail if any objects such as tables or sequences have been defined in the schema. Specify the CASCADE option to silently drop all database objects in the schema.

                Requires Administrative privileges.

                DROP TABLE

                DROP TABLE <table> [IF EXISTS] [RESTRICT | CASCADE];

                Removes a table, the data and indexes from the database. When IF EXIST is used, the statement returns without an error even if the table does not exist.

                The RESTRICT option is in effect by default, meaning that DROP will fail if any tables or views refer to this table. Specify the CASCADE option to silently drop all dependent views, and to drop any foreign key constraint that links this table with other tables.

                See also:

                CREATE TABLE.

                DROP TRIGGER

                DROP TRIGGER <trigger>;

                Removes a trigger from the database.

                See also: CREATE TRIGGER[2].

                DROP USER

                DROP USER <username>;

                Removes a user from the database.

                Only an administrator do this.

                See also: CREATE USER.

                DROP VIEW[2]

                DROP VIEW <viewname> [IF EXISTS] [RESTRICT | CASCADE];

                Removes a view from the database. When IF EXIST is used, the statement returns without an error if the view does not exist. The RESTRICT option is in effect by default, meaning that DROP will fail if any other view refers to this view. Specify the CASCADE option to silently drop all dependent views.

                See also: CREATE VIEW[2].

                EXPLAIN PLAN

                EXPLAIN PLAN FOR { SELECT ... | DELETE ... | INSERT ... | UPDATE ..};

                EXPLAIN PLAN FOR can be used with any query to get a detailed list of the elements in the execution plan.

                This list includes the indexes used for performing the query and can be used to optimise the query or to add indexes to tables.

                GRANT

                GRANT { SELECT | DELETE | INSERT | UPDATE | ALL } [,...]
ON { table | CLASS "package.class" } TO <grantee>;
                GRANT <rolename> [,...] TO <grantee>[2];

                <grantee> is either a user name, a role name, or PUBLIC. PUBLIC means all users.

                The first form of the GRANT command assigns privileges to a grantee for a table or for a class. To allow a user to call a Store Procedure static function, the right ALL must be used. Examples: 

                    GRANT SELECT ON Test TO GUEST;
    GRANT ALL ON CLASS "java.lang.Math.abs" TO PUBLIC;

                Warning

                Even though the command is GRANT ALL ON CLASS, you must specify a static method name. You are actually granting access to a static method, not to a class.

                The second form of the GRANT command gives the specified <grantee> membership in the specified role.

                Requires Administrative privileges.

                See also: REVOKE, CREATE USER, CREATE ROLE[2].

                INSERT

                INSERT INTO table [( column [,...] )]
{ VALUES(Expression [,...]) | SelectStatement};

                Adds one or more new rows of data into a table.

                REVOKE

                REVOKE { SELECT | DELETE | INSERT | UPDATE | ALL } [,...]
ON { table | CLASS "package.class" } FROM <grantee>;
                REVOKE <rolename> [,...] FROM <grantee>[2];

                <grantee> is either a user name, a role name, or PUBLIC. PUBLIC means all users.

                The first form of the REVOKE command withdraws privileges from a grantee for a table or for a class.

                The second form of the REVOKE command withdraws membership of the specified <grantee> from the specified role.

                Both forms require Administrative privileges.

                See also: GRANT.

                ROLLBACK

                ROLLBACK [TO SAVEPOINT <savepoint name>[2] |  WORK}];

                ROLLBACK used on its own, or with WORK, undoes changes made since the last COMMIT or ROLLBACK.

                ROLLBACK TO SAVEPOINT <savepoint name> undoes the change since the named savepoint. It has no effect if the savepoint is not found.

                See also: COMMIT.

                SAVEPOINT[2]

                SAVEPOINT <savepoint name>;

                Sets up a SAVEPOINT for use with ROLLBACK TO SAVEPOINT.

                See also: COMMIT.

                SCRIPT

                SCRIPT ['file'];

                Creates an SQL script describing the database. If the file is not specified, a result set containing only the DDL script is returned. If the file is specified then this file is saved with the path relative to the machine where the database engine is located.

                Only an administrator may do this.

                SELECT[2]

                SELECT [{LIMIT <offset> <limit> | TOP <limit>}[2]][ALL | DISTINCT]
{ selectExpression | table.* | * } [, ...]
[INTO [CACHED | TEMP  | TEXT][2] newTable]
FROM tableList
[WHERE Expression]
[GROUP BY Expression [, ...]]
[HAVING Expression]
[{ UNION [ALL | DISTINCT] | {MINUS [DISTINCT] | EXCEPT [DISTINCT] } |
INTERSECT [DISTINCT] } selectStatement]
[ORDER BY orderExpression [, ...]]
[LIMIT <limit> [OFFSET <offset>]];

                Retrieves information from one or more tables in the database.

                Components of a SELECT command

                tableList
                table [{CROSS | INNER | LEFT OUTER | RIGHT OUTER}
    JOIN table ON Expression] [, ...]
                table
                { (selectStatement) [AS] label | tableName}
                selectExpression
                { Expression | COUNT(*) | {
    COUNT | MIN | MAX | SUM | AVG | SOME | EVERY |
    VAR_POP | VAR_SAMP | STDDEV_POP | STDDEV_SAMP
} ([ALL | DISTINCT][2]] Expression) } [[AS] label]

                If DISTINCT is specified, only one instance of several equivalent values is used in the aggregate function. Except COUNT(*), all aggregate functions exclude NULL values. The type of the returned value for SUM is subject to deterministic widenning to ensure lossless results. The returned value type for COUNT is INTEGER, for MIN, MAX and AVG it is the same type as the column, for SOME and EVERY it is BOOLEAN. For VAR_POP, VAR_SAMP, STDDEV_POP and STDDEV_SAMP statistical functions, the type is always DOUBLE. These statistical functions do not allow ALL or DISTINCT qualifiers.

                If CROSS JOIN is specified no ON expression is allowed for the join.

                orderExpression
                { columnNr | columnAlias | selectExpression }
    [ASC | DESC]
                LIMIT n m

                Creates the result set for the SELECT statement first and then discards the first n rows (OFFSET) and returns the first m rows of the remaining result set (LIMIT). Special cases: LIMIT 0 m is equivalent to TOP m or FIRST m in other RDBMS's; LIMIT n 0 discards the first n rows and returns the rest of the result set.

                LIMIT m OFFSET n

                This form is used at the end of the SELECT statement. The OFFSET term is optional.

                TOP m

                Equivalent to LIMIT 0 m.

                UNION and other set operations

                Multiple SELECT statements joined with UNION, EXCEPT and INTERSECT are possible. Each SELECT is then treated as a term, and the set operation as an operator in an expression. The expression is evaluated from left to right but INTERSECT takes precedence over the rest of the operators and is applied first. You can use parentheses around any number of SELECT statements to change the evaluation order.

                See also: INSERT, UPDATE, DELETE.

                SET AUTOCOMMIT

                SET AUTOCOMMIT { TRUE | FALSE };

                Switches on or off the connection's auto-commit mode. If switched on, then all statements will be committed as individual transactions. Otherwise, the statements are grouped into transactions that are terminated by either COMMIT or ROLLBACK. By default, new connections are in auto-commit mode. This command should not be used directly. Use the JDBC equivalent method, Connection.setAutoCommit(boolean autocommit).

                SET DATABASE COLLATION[2]

                SET DATABASE COLLATION <double quoted collation name>;

                Each database can have its own collation. Sets the collation from the set of collations in the source for org.hsqldb.Collation.

                Once this command has been issued, the database can be opened in any JVM and will retain its collation.

                SET CHECKPOINT DEFRAG[2]

                SET CHECKPOINT DEFRAG <size>;

                The parameter size is the megabytes of abandoned space in the .data file. When a CHECKPOINT is performed either as a result of the .log file reaching the limit set by "SET LOGSIZE size", or by the user issuing a CHECKPOINT command, the amount of space abandoned during the session is checked and if it is larger than size, a CHECKPOINT DEFRAG is performed instead of a checkpoint.

                SET IGNORECASE

                SET IGNORECASE { TRUE | FALSE };

                Disables (ignorecase = true) or enables (ignorecase = false) the case sensitivity of text comparison and indexing for new tables. By default, character columns in new databases are case sensitive. The sensitivity must be switched before creating tables. Existing tables and their data are not affected. When switched on, the data type VARCHAR is set to VARCHAR_IGNORECASE in new tables. Alternatively, you can specify the VARCHAR_IGNORECASE type for the definition of individual columns. So it is possible to have some columns case sensitive and some not, even in the same table.

                Only an administrator may do this.

                SET INITIAL SCHEMA [2]

                Users may change their base default schema name with the comand 

                SET INITIAL SCHEMA <schemaname>;
                This is the schema which database object names will resolve to for the current user, unless overridden as explained in Schema object naming. For reasons of backwards compatibility, the initial schema value will not be persisted across database shutdowns until HSQLDB version 1.8.1. (I.e., INITIAL SCHEMA settings will be lost upon database shutdown with HSQLDB versions lower than version 1.8.1).

                SET LOGSIZE

                SET LOGSIZE <size>;

                Sets the maximum size in MB of the .log file. Default is 200 MB. The database will be closed and opened (just like using CHECKPOINT) if the .log file gets over this limit, and so the .log file will shrink. 0 means no limit.

                See also: CHECKPOINT.

                SET MAXROWS

                SET MAXROWS <maxwors>;

                Describe me!

                SET PASSWORD

                SET PASSWORD <password>;

                Changes the password of the currently connected user. Password must be double quotedEmpty password can be set using "".

                SET PROPERTY[2]

                SET PROPERTY <double quoted name> <value>;

                Sets a database property. Properties that can be set using this command are either boolean or integral and are listed in the Advanced Topics chapter.

                SET READONLY

                SET READONLY {TRUE|FALSE};

                Describe me!

                SET REFERENTIAL INTEGRITY

                SET REFERENTIAL_INTEGRITY { TRUE | FALSE };

                This commands enables / disables the referential integrity checking (foreign keys). Normally it should be switched on (this is the default) but when importing data (and the data is imported in the 'wrong' order) the checking can be switched off.

                Warning

                Note that when referential integrity is switched back on, no check is made that the changes to the data are consistent with the existing referential integrity constraints. You can verify consistency using SQL queries and take appropriate actions.

                Only an administrator may do this.

                See also: CREATE TABLE.

                SET SCHEMA[2]

                SET SCHEMA <schemaname>;

                Sets the current JDBC session's schema. The sole purpose for the session schema is to provide a default schema name for schema objects that do not have the schema name specified explicitly in the SQL command, or by association with another object of known schema. For example, if you run SELECT * FROM atbl;, HSQLDB will look for the table or view named atbl in the session's current schema.

                Session schemas last only for the duration of the current session. When a new JDBC session is obtained, the new session will have the default schema.

                SET SCRIPTFORMAT[2]

                SET SCRIPTFORMAT {TEXT | BINARY | COMPRESSED};

                Changes the format of the script file. BINARY and COMPRESSED formats are slightly faster and more compact than the default TEXT. Recommended only for very large script files.

                SET TABLE INDEX

                SET TABLE tableName INDEX 'index1rootPos index2rootPos ... ';

                This command is only used internally to store the position of index roots in the .data file. It appears only in database script files; it should not be used directly.

                SET TABLE READONLY[2]

                SET TABLE <tablename> READONLY {TRUE | FALSE};

                Sets the table as read only.

                SET TABLE SOURCE[2]

                SET TABLE <tablename> SOURCE <file and options> [DESC];

                For details see the Text Tables chapter.

                This command is used exclusively with TEXT tables to specify which file is used for storage of the data. The optional DESC qualifier results in the text file indexed from the end and opened as readonly. The <file and options> argument is a double quoted string that consists of:

                    <file and options>::= <doublequote> <filepath>
        [<semicolon> <option>...] <doublequote>

                Example:

                    SET TABLE mytable SOURCE "myfile;fs=|;vs=.;lvs=~"

                Supported Properties

                quoted = { true | false }

                default is true. If false, treats double quotes as normal characters

                all_quoted = { true | false }

                default is false. If true, adds double quotes around all fields.

                encoding = <encoding name>

                character encoding for text and character fields, for example, encoding=UTF-8

                ignore_first = { true | false }

                default is false. If true ignores the first line of the file

                cache_scale= <numeric value>

                exponent to calculate rows of the text file in cache. Default is 8, equivalent to nearly 800 rows

                cache_size_scale = <numeric value>r

                exponent to calculate average size of each row in cache. Default is 8, equivalent to 256 bytes per row.

                fs = <unquoted character>

                field separator

                vs = <unquoted character>

                varchar separator

                lvs = <unquoted character>

                long varchar separator

                Special indicators for Hsqldb Text Table separators

                \semi

                semicolon

                \quote

                quote

                \space

                SET WRITE DELAY[2]

                SET WRITE_DELAY {{ TRUE | FALSE } | <seconds> | <milliseconds> MILLIS};

                This controls the frequency of file sync for the log file. When WRITE_DELAY is set to FALSE or 0, the sync takes place immediately at each COMMIT. WRITE_DELAY TRUE performs the sync once every 20 seconds (which is the default). A numeric value can be specified instead.

                The purpose of this command is to control the amount of data loss in case of a total system crash. A delay of 1 second means at most the data written to disk during the last second before the crash is lost. All data written prior to this has been synced and should be recoverable.

                A write delay of 0 impacts performance in high load situations, as the engine has to wait for the file system to catch up.

                To avoid this, you can set write delay down to 10 milliseconds. In practice, a write delay of 100 milliseconds provides better than 99.9999% reliability with an average one system crash per day, or 99.99999% with an average one system crash per 6 days.

                Each time a SET WRITE_DELAY is issued with any value, a sync is immediately performed.

                Only an administrator may do this.

                SHUTDOWN

                SHUTDOWN [IMMEDIATELY | COMPACT | SCRIPT[2]];

                Closes the current database.

                Varieties of the SHUTDOWN command

                SHUTDOWN

                Performs a checkpoint to creates a new .script file that has the minimum size and contains the data for memory tables only. It then backs up the .data file containing the CACHED TABLE data in zipped format to the .backup file and closes the database.

                SHUTDOWN IMMEDIATELY

                Just closes the database files (like when the Java process for the database is terminated); this command is used in tests of the recovery mechanism. This command should not be used as the routine method of closing the database.

                SHUTDOWN COMPACT

                Writes out a new .script file which contains the data for all the tables, including CACHED and TEXT tables. It then deletes the existing text table files and the .data file before rewriting them. After this, it backs up the .data file in the same way as normal SHUTDOWN. This operation shrinks all files to the minimum size.

                SHUTDOWN SCRIPT

                Similar to SHUTDOWN COMPACT but after writing the script and deleting the existing files, it does not rewrite the .data and text table files. After SHUTDOWN SCRIPT, only the .script and .properties file remain. At the next startup, these files are processed and the .data and .backup files are created. This command in effect performs part of the job of SHUTDOWN COMPACT, leaving the other part to be performed automatically at the next startup.

                This command produces a full script of the database which can be edited for special purposes prior to the next startup.

                Only an administrator may use the SHUTDOWN command.

                UPDATE

                UPDATE table SET column = Expression [, ...] [WHERE Expression];

                Modifies data of a table in the database.

                See also: SELECT[2], INSERT, DELETE.

                Schema object naming

                Schema objects are database objects that are always scoped to a specific schema. Each schema has a namespace. There may be multiple schema objects of the same name, each in the namespace of a different schema. A particular schema object may nearly always be uniquely identified using the notation schemaname.objectname. All HSQLDB database objects are schema objects, other than the following.

                Users

                Roles

                Store Procedure Java Classes

                HSQL Aliases

                Our current Java-class-based Triggers are not fully schema objects. However, we are in the process of implementing SQL-conformant triggers which will encompass our Java-class-based triggers. When this work is completed, HSQLDB triggers will be schema objects.

                Sequences are schema objects with creation and removal permission governed by schema authorization (as described hereafter), but GRANT and REVOKE command do not work yet for sequences. In a future version of HSQLDB, sequence GRANTs and REVOKEs will work similarly to the current GRANT and REVOKE commands for table access.

                Most of the time, you do not need to specify the schema for the desired schema object, because the implicit schema is usually the only one that can be used. For example, when creating an index, the target schema will default to that of the table which is the target of the index. Named constraints are an extreme example of this. There is never a need to specify a schema name for a constraint, since constraint names are only specified in a CREATE or ALTER TABLE command, and the schema must be that of the target table. If the implicit schema is not determined by a related object, then the default comes from your JDBC session's current schema setting. The session schema value will be your login user's initial schema, or whatever you last set it to with SET SCHEMA[2] in your current JDBC session with the SET SCHEMA command. (Your initial schema is "PUBLIC" unless changed with the ALTER USER SET INITIAL SCHEMA or the SET INITIAL SCHEMA [2] command).

                In addition to namespace scoping, there are permission aspects to the schema of a database object. The authorization of a schema is a role or user that is basically the owner of the schema. Only a user with the DBA role (an admin user) or the owner of a schema may create objects, or modify the DDL of objects, in the namespace of that schema. In this way, a schema authorization is said to "own" the objects of that schema. A schema authorization/owner can be a role or a user (even a role with no members). The two schemas automatically created when a database is initialized are both owned by the role DBA.

                An important implication to database objects being owned by the schema owner is, if a non-DBA database user is to have permission to create any database object, they must have ownership of a schema. To allow a user to create (or modify DDL of) objects in their own personal schema, you would create a new schema with that user as the authorization. To allow a non-DBA user to share create and DDL privileges in some schema, you would create this schema with a role as the authorization, then GRANT this role to all of the desired users.

                The INFORMATION_SCHEMA is a system defined schema that contains the system tables for the database. This schema is read-only. When a database is created, a shema named PUBLIC is automatically created as the default schma. This schema has the authorization DBA. You can change the name of this schema. If all non-system schemas are dropped from a database, an empty PUBLIC schema is created again. So each database always has at least one non-system schema.

                LONGVARBINARYas Integer.MAXVALUEbyte[]
                OTHER | OBJECTas Integer.MAXVALUEjava.lang.Object

                The uppercase names are the data types names defined by the SQL standard or commonly used by RDMS's. The data types in quotes are the Java class names - if these type names are used then they must be enclosed in quotes because in Java names are case-sensitive. Range indicates the maximum size of the object that can be stored. Where Integer.MAXVALUE is stated, this is a theoretical limit and in practice the maximum size of a VARCHAR or BINARY object that can be stored is dictated by the amount of memory available. In practice, objects of up to a megabyte in size have been successfully used in production databases.

                The recommended Java mapping for the JDBC datatype FLOAT is as a Java type "double". Because of the potential confusion it is recommended that DOUBLE is used instead of FLOAT.

                VARCHAR_IGNORECASE is a special case-insensitive type of VARCHAR. This type is not portable.

                In table definition statements, HSQLDB accepts size, precision and scale qualifiers only for certain types: CHAR(s), VARCHAR(s), DOUBLE(p), NUMERIC(p), DECIMAL(p,s) and TIMESTAMP(p).

                TIMESTAMP(p) can take only 0 or 6 as precision. Zero indicates no subsecond part. Without the precision, the default is 6.

                By default specified precision and scale for the column is simply ignored by the engine. Instead, the values for the corresponding Java types are always used, which in the case of DECIMAL is an unlimited precision and scale. If a size is specified, it is stored in the database definition but is not enforeced by default. Once you have created the database (before adding data), you can add a database property value to enforce the sizes:

                    SET PROPERTY "sql.enforce_strict_size" true

                This will enforce the specified size and pad CHAR fields with spaces to fill the size. This complies with SQL standards by throwing an exception if an attempt is made to insert a string longer than the maximum size. It also results in all DECIMAL values conforming to the specified precision and scale.

                CHAR and VARCHAR and LONGVARCHAR columns are by default compared and sorted according to POSIX standards. See the SET DATABASE COLLATION[2] section above to modify this behavior. The property sql.compare_in_locale is no longer supported. Instead, you can define a collation to be used for all character comparisons.

                Columns of the type OTHER or OBJECT contain the serialized form of a Java Object in binary format. To insert or update such columns, a binary format string (see below under Expression) should be used. Using PreparedStatements with JDBC automates this transformation.

                SQL Comments

                -- SQL style line comment
                // Java style line comment
                /* C style line comment */

                All these types of comments are ignored by the database.

                Stored Procedures / Functions

                Stored procedures are static Java functions that are called directly from the SQL language or using an alias. Calling Java functions (directly or using the alias) requires that the Java class can be reached by the database (server). The syntax is:

                    "java.lang.Math.sqrt"(2.0)

                This means the package must be provided, and the name must be written as one word, and inside " because otherwise it is converted to uppercase (and not found).

                An alias can be created using the command CREATE ALIAS:

                    CREATE ALIAS SQRT FOR "java.lang.Math.sqrt";

                When an alias is defined, then the function can be called additionally using this alias:

                    SELECT SQRT(A) , B FROM MYTABLE;

                Only static java methods can be used as stored procedures. If, within the same class, there are overloaded methods with the same number of arguments, then the first one encountered by the program will be used. If you want to use Java library methods, it is recommended that you create your own class with static methods that act as wrappers around the Java library methods. This will allow you to control which method signature is used to call each Java library method.

                SQL Expression

                [NOT] condition [{ OR | AND } condition]

                Components of SQL Expressions

                condition
                   { value [|| value]
  | value { = | < | <= | > | >= | <> | != } value
  | value IS [NOT] NULL
  | EXISTS(selectStatement)
  | value BETWEEN value AND value
  | value [NOT] IN ( {value [, ...] | selectStatement } )
  | value [NOT] LIKE value [ESCAPE] value }
                value
                   [+ | -] { term [{ + | - | * | / | || } term]
  | ( condition )
  | function ( [parameter] [,...] )
  | selectStatement giving one value
  | {ANY|ALL} (selectStatement giving single column)
                term
                   { 'string' | number | floatingpoint
  | [table.]column | TRUE | FALSE | NULL }
                sequence
                   NEXT VALUE FOR <sequence>

                HSQLDB does not currently enforce the SQL 200n proposed rules on where sequence generated values are allowed to be used. In general, these values can be used in insert and update statements but not in CASE statements, order by clauses, search conditions, aggregate functions, or grouped queries.

                string

                Strings in HSQLDB are Unicode strings. A string starts and ends with a single ' (singlequote). In a string started with ' (singlequote) use '' (two singlequotes) to create a ' (singlequote).

                String contatenation should be performed with the standard SQL operator || rather than the non-standard + operator.

                The LIKE keyword uses '%' to match any (including 0) number of characters, and '_' to match exactly one character. To search for '%' or '_' itself an escape character must also be specified using the ESCAPE clause. For example, if the backslash is the escaping character, '\%' and '\_' can be used to find the '%' and '_' characters themselves. For example, SELECT .... LIKE '\_%' ESCAPE '\' will find the strings beginning with an underscore.

                name

                The character set for quoted identifiers (names) in HSQLDB is Unicode.

                A unquoted identifier (name) starts with a letter and is followed by any number of ASCII letters or digits. When an SQL statement is issued, any lowercase characters in unquoted identifiers are converted to uppercase. Because of this, unquoted names are in fact ALL UPPERCASE when used in SQL statements. An important implication of this is the for accessing columns names via JDBC DatabaseMetaData: the internal form, which is the ALL UPPERCASE must be used if the column name was not quoted in the CREATE TABLE statement.

                Quoted identifiers can be used as names (for tables, columns, constraints or indexes). Quoted identifiers start and end with " (one doublequote). A quoted identifier can contain any Unicode character, including space. In a quoted identifier use "" (two doublequotes) to create a " (one doublequote). With quoted identifiers it is possible to create mixed-case table and column names. Example:

                    CREATE TABLE "Address" ("Nr" INTEGER,"Name" VARCHAR);
    SELECT "Nr", "Name" FROM "Address";

                The equivalent quoted identifier can be used for an unquoted identifer by converting the identifier to all uppercase and quoting it. For example, if a table name is defined as Address2 (unquoted), it can be referred to by its quoted form, "ADDRESS2", as well as address2, aDDress2 and ADDRESS2. Quoted identifiers should not be confused with SQL strings.

                Quoting can sometimes be used for identifiers, aliases or functions when there is an ambiguity. For example:

                    SELECT COUNT(*) "COUNT" FROM MYTABLE;
    SELECT "LEFT"(COL1, 2) FROM MYTABLE;

                Although HSQLDB 1.8.0 does not force unquoted identifiers to contain only ASCII characters, the use of non-ASCII characters in these identifiers does not comply with SQL standards. Portability between different JRE locales could be an issue when accented characters (or extended unicode characters) are used in unquoted identifiers. Because native Java methods are used to convert the identifier to uppercase, the result may vary not be expected in different locales. It is recommended that accented characters are used only in quoted identifiers.

                When using JDBC DatabaseMetaData methods that take table, column, or index identifiers as arguments, treat the names as they are registered in the database. With these methods, unquoted identifiers should be used in all-uppercase to get the correct result. Quoted identifiers should be used in the exact case combination as they were defined - no quote character should be included around the name. JDBC methods that return a result set containing such identifiers return unquoted identifiers as all-uppercase and quoted identifiers in the exact case they are registered in the database (a change from 1.6.1 and previous versions).

                Please also note that the JDBC getXXX(String columnName) methods interpret the columnName as case-independent. This is a general feature of JDBC and not specific to HSQLDB.

                password

                Passwords must be double quoted and used consistently. Passwords are case insensitive only for backward compatibility. This may change in future versions.

                values

                • A DATE literal starts and ends with ' (singlequote), the format is yyyy-mm-dd (see java.sql.Date.

                • A TIME liteal starts and ends with ' (singlequote), the format is hh:mm:ss (see java.sql.Time).

                • A TIMESTAMP or DATETIME literal starts and ends with ' (singlequote), the format is yyyy-mm-dd hh:mm:ss.SSSSSSSSS (see java.sql.Timestamp).

                When specifying default values for date / time columns in CREATE TABLE statements, or in SELECT,INSERT, and UPDATE statements, special SQL functions: NOW, SYSDATE, TODAY, CURRENT_TIMESTAMP, CURRENT_TIME and CURRENT_DATE (case independent) can be used. NOW is used for TIME and TIMESTAMP columns, TODAY is used for DATE columns. The data and time variants CURRENT_* are SQL standard versions and should be used in preference to others. Example:

                    CREATE TABLE T(D DATE DEFAULT CURRENT_DATE);
    CREATE TABLE T1(TS TIMESTAMP DEFAULT CURRENT_TIMESTAMP);

                Binary data starts and ends with ' (singlequote), the format is hexadecimal. '0004ff' for example is 3 bytes, first 0, second 4 and last 255 (0xff).

                Any number of commands may be combined. With combined commands, ';' (semicolon) must be used at the end of each command to ensure data integrity, despite the fact that the engine may understand the end of commands and not return an error when a semicolon is not used.


                [2] These features were added by HSQL Development Group since April 2001

                Ant is a part of the Jakarta/Apache Project.

                Once you have unpacked the zip package for hsqldb, under the /hsqldb folder, in /build there is a build.xml file that builds the hsqldb.jar with Ant (Ant must be already installed). To use it, change to /build then type:

                 ant -projecthelp

                This displays the available ant targets, which you can supply as command line arguments to ant. These include

                hsqldb

                to make the hsqldb.jar

                explainjars

                Lists all targets which build jar files, with an explanation of the purposes of the different jars.

                clean

                to clean up the /classes directory that is created

                cleanall

                to remove the old jar as well

                javadoc

                to build javadoc

                hsqldbmain

                to build a smaller jar for HSQLDB that does not contain utilities

                hsqljdbc

                to build an extremely small jar containing only the client-side JDBC driver (does not support direct connection to HSQLDB URLs of the form jdbc:hsldb:mem:*, jdbc:hsqldb:file:*, nor jdbc:hsqldb:res:*).

                hsqldbmin

                to build a small jar that supports HSQLDB URLs of the form jdbc:hsqldb:mem:*, jdbc:hsqld:file*, jdbc:hsqldb:res:*; but not network URLs like jdbc:hsql* or jdbc:http*.

                hsqldbtest

                to build a larger jar for hsqldb that contains tests

                ...

                Many more targets are available. Run ant -projecthelp and ant explainjars.

                HSQLDB can be built in any combination of three JRE (Java Runtime Environment) versions and many jar file sizes. The smallest jar size(hsqljdbc.jar) contains only the HSQLDB JDBC Driver client. The default size (hsqldb.jar) also contains server mode support and the utilities. The largest size (hsqldbtest.jar)includes some test classes as well. Before building the hsqldbtest.jar package, you should download the junit jar from http://www.junit.org and put it in the /lib directory, alongside servlet.jar, which is included in the .zip package.

                Just run ant explainjars for a concise list of all available jar files.

                If you want your code built for debugging, as opposed to high performance, make a file named build.properties in your build directory with the contents 

                build.debug: true
                The resulting Java binaries will be larger and slower, but exception stack traces will contain source code line numbers, which can be extremely useful for debugging.

                The preferred method of rebuilding the jar is with Ant. After installing Ant on your system use the following command from the /build directory:

                ant explainjars

                The command displays a list of different options for building different sizes of the HSQLDB Jar. The default is built using:

                Example A.1. Buiding the standard Hsqldb jar file with Ant

                ant hsqldb

                The Ant method always builds a jar with the JDK that is used by Ant and specified in its JAVA_HOME environment variable. Building with JDK 1.4.x or 1.5.x will result in a jar that is not backward compatible.

                From version 1.7.2, use of JDK 1.1.x is not recommended for building the JAR, even for running under JDK 1.1.x -- use JDK 1.3.1 for compatibility with 1.1.x. This is done in the following way. JDK 1.3.1 should be used as the JAVA_HOME for ant. You then issue the following commands. The first command will make the sources compatible with JDK 1.3, the second command modifies the sources further so that the compiled result can run under jdk 1.1 as well. The third command builds the jar.

                ant switchtojdk12
ant switchtojava1target
ant hsqldb

                Building with DOS Batch Files

                UNIX users must use Ant to build hsqldb.

                For DOS/Windows users, a set of MSDOS batch files is provided as an example. These files produce only the default jar size. The path and classpath variables for the JDK should of course be set before running any of the batch files. These files are not currently maintained and will probably need some additions and changes to work correctly. Please see the build.xml file for up-to-date file

                If you are compiling for JDK's other than 1.4.x, you should use the appropriate switchToJDK11.bat or switchToJDK12.bat to adapt the source files to the target JDK before running the appropriate buildJDK11.bat or buildJDK12.bat JDK and JRE versions.

                Hsqldb CodeSwitcher

                CodeSwitcher is a tool to manage different version of Java source code. It allows to compile HSQLDB for different JDKs. It is something like a precompiler in C but it works directly on the source code and does not create intermediate output or extra files.

                CodeSwitcher is used internally in HSQLDB build scripts. You do not have to use it separately to compile HSQLDB.

                CodeSwitcher reads the source code of a file, removes comments where appropriate and comments out the blocks that are not used for a particular version of the file. This operation is done for all files of a defined directory, and all subdirectories.

                Example A.2. Example source code before CodeSwitcher is run

                        ...

    //#ifdef JAVA2

        properties.store(out,"hsqldb database");

    //#else

    /*

        properties.save(out,"hsqldb database");

    */

    //#endif

        ...

                The next step is to run CodeSwitcher.

                Example A.3. CodeSwitcher command line invocation

                    java org.hsqldb.util.CodeSwitcher . -JAVA2

                The '.' means the program works on the current directory (all subdirectories are processed recursively). -JAVA2 means the code labelled with JAVA2 must be switched off.

                Example A.4. Source code after CodeSwitcher processing

                        ...

    //#ifdef JAVA2

    /*

        pProperties.store(out,"hsqldb database");

    */

    //#else

        pProperties.save(out,"hsqldb database");

    //#endif

        ...

                For detailed information on the command line options run java org.hsqldb.util.CodeSwitcher. Usage examples can be found in the switchtojdk1*.bat files in the /build directory.

                Building documentation

                To build the User Guide in HTML format, you must have the Docbook stylesheets installed locally. The Docbook stylesheets are available on the Internet. On Linux, just install the docbook-xsl-stylesheets rpm. Then add an entry to build.properties in your build directory with contents like 

                docbook.xsl.home: /usr/share/sgml/docbook/docbook-xsl-stylesheets
                Where you specify your local path to the base directory of your Docbook stylesheet installation. Build like

                Example A.5. Building HTML User Guides

                ant docbooks-html
ant docbooks-chunk

                To build the User Guide in PDF format, you must also have the Java FOP system installed locally. FOP is available for free download on the Internet. Add an entry to build.properties in your build directory with contents like 

                fop.home /usr/local/fop-0.20.5
                Where you specify your local path to the base directory of your FOP installation.

                Example A.6. Building User Guides in all formats

                ant docbook
                Don't pay too much attention to error messages by FOP, because they are really warnings, but do check the output. If there are problems with the PDF output, try using a newer version of FOP.

                Important

                By default, your docs will fail to build if you do not have Internet connectivity. This is because our primary Docbook source file references the Docbook DTDs via Internet URL. You can build without Internet connectivity by installing the Docbook DTDs and editing our primary Docbook source file. Docbook is available on the Internet. On Linux, just install the docbook-dtds or docbook rpm. Then make one edit to the file docsrc/guide/guide.xml in your HSQLDB distribution. Change the line containing 

                "http://www.oasis-open.org/docbook/xml/4.2CR1/docbookx.dtd" [
                to 
                "file:///usr/share/xml/docbook/schema/dtd/4.2/docbookx.dtd" [
                where the second filepath is the path to the docbookx.dtd file within your Docbook installation.

                This text is based on HypersonicSQL documentation, updated to reflect the latest version 1.8.0 of HSQLDB.

                $Date: 2005/07/01 17:06:32 $

                Table of Contents

                States
                Procedures
                Clean Shutdown
                Startup
                Repair

                The Standalone and Client/Server modes will in most cases use files to store all data to disk in a persistent and safe way. This document describes the meaning of the files, the states and the procedures followed by the engine to recover the data.

                A database named 'test' is used in this description. The database files will be as follows.

                Database Files

                test.properties

                Contains the entry 'modified'. If the entry 'modified' is set to 'yes' then the database is either running or was not closed correctly (because the close algorithm sets 'modified' to 'no' at the end).

                test.script

                This file contains the SQL statements that makes up the database up to the last checkpoint - it is in synch with test.backup.

                test.data

                This file contains the (binary) data records for CACHED tables only.

                test.backup

                This is compressed file that contains the complete backup of the old test.data file at the time of last checkpoint.

                test.log

                This file contains the extra SQL statements that have modified the database since the last checkpoint (something like the 'Redo-log' or 'Transaction-log', but just text).

                In the above list, a checkpoint results from both a CHECKPOINT command and a SHUTDOWN command.

                States

                Database is closed correctly

                State after using the command SHUTDOWN

                • The test.data file is fully updated.

                • The test.backup contains the compressed test.data file.

                • The test.script contains the information in the database, excluding data for CACHED and TEXT tables.

                • The test.properties contains the entry 'modified' set to 'no'.

                • There is no test.log file.

                Database is closed correctly with SHUTDOWN SCRIPT

                State after using the command SHUTDOWN SCRIPT

                • The test.data file does not exist; all CACHED table data is in the test.script file

                • The test.backup does not exist.

                • The test.script contains the information in the database, including data for CACHED and TEXT tables.

                • The test.properties contains the entry 'modified' set to 'no'.

                • There is no test.log file.

                Database is aborted

                This may happen by sudden power off, Ctrl+C in Windows, but may be simulated using the command SHUTDOWN IMMEDIATELY.

                Aborted Database state

                • The test.properties still containes 'modified=yes'.

                • The test.script contains a snapshot of the database at the last checkpoint and is OK.

                • The test.data file may be corrupt because the cache in memory was not written out completely.

                • The test.backup file contains a snapshot of test.data that corresponds to test.script.

                • The test.log file contain all information to re-do all changes since the snanapshot. As a result of abnormal termination, this file may be partially corrupt.

                Procedures

                The database engine performs the following procedures internally in different circumstances.

                Clean Shutdown

                Procedure C.1. Clean Hsqldb database shutdown

                1. The test.data file is written completely (all the modified cached table rows are witten out) and closed.

                2. The test.backup.new is created (containing the compressed test.data file)

                3. The file test.script.new is created using the information in the database (and thus shrinks because no UPDATE and DELETE statements; only INSERT).

                4. The entry 'modified' in the properties file is set to 'yes-new-files'

                5. The file test.script is deleted

                6. The file test.script.new is renamed to test.script

                7. The file test.backup is deleted

                8. The file test.backup.new is renamed to test.backup

                9. The entry 'modified' in the properties file is set to 'no'

                10. The file test.log is deleted

                Startup

                Procedure C.2. Database is opened

                1. Check if the database files are in use (by checking a special test.lck file).

                2. See if the test.properties file exists, otherwise create it.

                3. If the test.properties did not exist, then this is a new database. Create the empty test.log to append new commands.

                4. If it is an existing database, check in the test.properties file if 'modified=yes'. This would mean last time it was not closed correctly, and thus the test.data file may be corrupted or incomplete. In this case the 'REPAIR' algorithm is executed (see below), before the database is opened normally.

                5. Otherwise, if in the test.properties file 'modified=yes-new-files', then the (old) test.backup and test.script files are deleted and the new test.script.new file is renamed to test.script.

                6. Open the test.script file and execute the commands.

                7. Create the empty test.log to append new commands.

                Repair

                The current test.data file is corrupt, but with the old test.data (from the test.backup file and test.script) and the current test.log, the database is made up-to-date. The database engine takes these steps:

                Procedure C.3. Database Repair

                1. Restore the old test.data file from the backup (uncompress the test.backup and overwrite test.data).

                2. Execute all commands in the test.script file.

                3. Execute all commands in the test.log file. If due to corruption, an exception is thrown, the rest of the lines of command in the test.log file are ignored.

                4. Close the database correctly (including a backup).

                On Linux

                Introduction

                HSQLDB can now act as a Database with OpenOffice.org. This document is written to help you connecting and running HSQLDB out of OpenOffice.org in a simple way. Without user-managment and only for your single-system.

                If you have problems read the other available documents, because I will not write them here again. If you need a real DB-System with user-management and different rights for different users, read the other documents.

                HSQLDB is included with OpenOffice.org 2.0 and is used by default. Please refer to standard OpenOffice.org 2.0 documentation on how to use HSQLDB with this version.

                Installing

                I assume you have a running OpenOffice.org (OOo) and a JavaRuntimeEnvironment. So place the hsqldb_*.zip file where you want on your disk and unpack it (I assume you have done this already).

                Setting up OpenOffice.org

                Start OOo with a text document and go to the Database-Explorer (simply by pressing F4). In the left frame you see a tree-view with all known databases in OOo.

                A right mouse-click opens a menu where you can manage your databases. So click on New Database and choose a name that you want to have inside OOo. I chose HSQLDB as name.

                As connection-type choose JDBC and then switch to the JDBC-tab.

                As Driver-Class insert org.hsqldb.jdbcDriver and as URL choose the following:

                On Windows

                You can specify a directory where HSQLDB should store the info and data. Something like jdbc:hsqldb:file:c:\javasrc\hsqldb-dev\databasename (where jdbc: is written by OOo). The string c:\javasrc\hsqldb-dev\databasename works only on windows, but you can write this down as linux-path like /javasrc/hsqldb-dev/databasename too. Then HSQLDB takes the c:\ drive as root. This means this works only on c:\ for you.

                The first is the directory-path and the databasename is the identifier for the database.

                On Linux

                Choose a path as said for windows like /opt/db/data

                As username take sa, this is the standard-administrator for HSQLDB.

                Now click the OK-Button

                Now OOo has to find your hsqldb.jar file. So go to options => security and insert the path to the .jar file. If you have problems, search the Online-help for JDBC. You then get help in your own language (this is generally quite better than my English, I think ;-)

                If you cannot write to your Tables, OOo thinks that you don't have permission to write to HSQLDB. Then we tell OOo to ignore the DriverPrivileges because on our single-user-system we do not need them.

                Because OOo is working on this, the next Step is only needed for systems without write - permission.

                So we go to http://dba.openoffice.org and look at the IgnoreDriverPrivileges.html file in the HowTo-section. You find here a macro-code.

                Open tools => macro in OOo to get the Basic-IDE. Here simple copy and paste the code and run the macro. You see a input-box where you only have to insert the name of your DB, in my example I have to insert HSQLDB, because I took this as name in OOo.

                Note that if you change your OOo-DB name, you have to run this macro again!

                Now we only have to stop and restart OOo. Be sure that you exit Quickstarter and all running processes too. On next OOo-Start you should have a running Database in OpenOffice.org.

                Appendix E. Hsqldb Test Utility

                $Date: 2005/05/27 12:41:50 $

                The org.hsqldb.test package contains a number of tests for various functions of the database engine. Among these, the TestSelf class performs the tests that are based on scripts. To run the tests, you should compile the hsqldbtest.jar target with Ant.

                For TestSelf, a batch file is provided in the testrun/hsqldb directory, together with a set of TestSelf*.txt files. To start the application in Windows, change to the directory and type:

                    runtest TestSelf

                In Unix / Linux, type:

                    ./runTest.sh TestSelf

                The new version of TestSelf runs multiple SQL test files to test different SQL operations of the database. All files in the working directory with names matching TestSelf*.txt are processed in alphabetical order.

                You can add your own scripts to test different series of SQL queries. The format of the TestSelf*.txt file is simple text, with some indentation and prefixes in the form of Java-style comments. The prefixes indicate what the expected result should be.

                • Comment lines must start with -- and are ignored

                • Lines starting with spaces are the continuation of the previous line

                • SQL statements with no prefix are simply executed.

                • The remaining items in this list exemplify use of the available command line-prefixes.

                • The /*s*/ option stands for silent. It is used for executing quries regardless of results. Used for preparation of tests, not for actual tests.

                  /*s*/ Any SQL statement - errors are ignored

                • The /*c<rows>*/ option is for SELECT queries and asserts the number of rows in the result matches the given count.

                  /*c<rows>*/ SQL statement returning count of <rows>

                • The /*u*/ option is for queries that return an update count, such as DELETE and UPDATE. It asserts the update count matches.

                  /*u<count>*/ SQL statement returning an update count equal to <count>

                • The /*e*/ option asserts that the given query results in an erros. It is mainly used for testing the error detection capabilities of the engine. It can also be used with syntactically valid queries to assert a certain state in the database. For example a CREATE TABLE can be used to assert the table of the same name already exists.

                  /*e*/ SQL statement that should produce an error when executing

                • The /*r....*/ option asserts the SELECT query returns a single row containing the given set of field values.

                  /*r<string1>,<string2>*/ SQL statement returning a single row ResultSet equal to the specified value

                • The extended /*r...*/ option asserts the SELECT query returns the given rows containing the given set of field values.

                  /*r
    <string1>,<string2>
    <string1>,<string2>
    <string1>,<string2>
*/ SQL statement returning a multiple row ResultSet equal to the specified values

                  (note that the result set lines are indented).

                • All the options are lowercase letters. During development, an uppercase can be used for a given test to exclude a test from the test run. The utility will just report the test blocks that have been excluded without running them. Once the code has been developed, the option can be turned into lowercase to perform the actual test.

                See the TestSelf*.txt files in the /testrun/hsqldb/ directory for actual examples.

                Auto tree-update
                Automatic Connection
                RC File

                DatabaseManagerSwing as an Applet

                Brief Introduction

                The Database Manager tool is a simple GUI database query tool with a tree display of the tables. Both AWT and SWING versions of the tool are available and work almost identically. The AWT version class name is org.hsqldb.util.DatabaseManager; the SWING version, org.hsqldb.util.DatabaseManagerSwing.

                The AWT version of the database manager can be deployed as an applet in a browser. A demo HTML file with an embedded Database Manager is included in the /demo directory.

                When the Database Manager is started, a dialogue allows you to enter the JDBC driver, URL, user and password for the new connection. A drop-down box, Type, offers preset values for JDBC driver and URL for most popular database engines, including HSQLDB. Once you have selected an item from this drop-down box, you should edit the URL to specify the details of the database or any additional properties to pass. You should also enter the username and password before clicking on the OK button.

                The connection dialogue allows you to save the settings for the connection you are about to make. You can then access the connection in future sessions. To save a connection setting, enter a name in the Setting Name box before clicking on the OK button. Next time the connection dialogue is displayed, the drop-down box labeled Recent will include the name for all the saved connection settings. When you select a name, the individual settings are displayed in the appropriate boxes.

                The small Clr button next to the drop-down box allows you to clear all the saved settings. If you want to modify an existing setting, first select it from the drop-down box then modify any of the text boxes before making the connection. The modified values will be saved.

                Most menu items have context-sensitive tool tip help text which will appear if you hold the mouse cursor still over the desired menu item. (Assuming that you don't turn Tooltips off under the Help menu.

                The DatabaseManagers do work with HSQLDB servers serving TLS-encrypted JDBC data. See the TLS chapter and the RC File Authentication Setup section of this Guide.

                Tip

                If you are using DatabaseManagerSwing with Oracle, you will want to make sure that Show row counts and Show row counts are both off before connecting to the database. You may also want to turn off Auto tree-update, as described in the next section.

                Auto tree-update

                By default, the object tree in the left panel is refreshed when you execute DDL which may update those objects. If you are on a slow network or performance-challenged PC, use the view / Auto-refresh tree menu item to turn it off. You will then need to use the viewRefresh tree menu item every time that you want to refresh the tree.

                Note

                Auto-refresh tree does not automatically show all updates to database objects, it only refreshes when you submit DDL which may update database objects. (This behavior is a compromise between utility and performance).

                Automatic Connection

                You can use command-line switches to supply connection information. If you use these switch(es), then the connection dialog window will be skipped and a JDBC connection will be established immediately. Assuming that the hsqldb.jar (or an alternative jar) are in your CLASSPATH, this command will list the available command-line options. 

                    java org.hsqldb.util.DatabaseManagerSwing --help

                It's convenient to skip the connection dialog window if you always work with the same database account.

                Warning

                Use of the --password switch is not secure. Everything typed on command-lines is generally available to other users on the computer. The problem is compounded if you use a network connection to obtain your command line. The RC File section explains how you can set up automatic connections without supplying a password on the command line.

                RC File

                You can skip the connection dialog window securely by putting the connection information into an RC file and then using the --urlid switch to DatabaseManager or DatabaseManagerSwing. This strategy is great for adding launch menu items and/or launch icons to your desktop. You can set up one icon for each of the database accounts which you regularly use.

                The default location for the RC file is dbmanager.rc in your home directory. The RC File Authentication Setup section explains how to put the connection information into this text file. If you also run SqlTool, then you can share the RC file with SqlTool by using a sym-link (if your operating system supports sym links), or by using the --rcfile switch for either SqlTool or DatabaseManagerSwing.

                Warning

                Use your operating system facilities to prevent others from reading your RC file, since it contains passwords.

                To set up launch items/icons, first experiment on your command line to find exactly what command works. For example, 

                    java -cp /path/to/hsqldb.jar org.hsqldb.util.DatabaseManagerSwing --urlid mem
                Then, use your window manager to add an item that runs this command.

                Using the current DatabaseManagers with an older HSQLDB distribution.

                This procedure will allow users of a legacy version of HSQLDB to use all of the new features of the DatabaseManagers. You will also get the new version of the SqlTool! This procedure works for distros going back to 1.7.3.3 at least, probably much farther.

                These instructions assume that you are capable of running an Ant build. See the Building HSQLDB chapter.

                1. Download and extract a current HSQLDB distribution. If you don't want to use the source code, documentation, etc., you can use a temporary directory and remove it afterwards.

                2. Cd to the build directory under the root directory where you extracted the distribution to.

                3. Run ant hsqldbutil.

                4. If you're going to wipe out the build directory, copy hsqldbutil.jar to a safe location first.

                5. For now on, whenver you are going to run DatabaseManager*, make sure that you have this hsqldbutil.jar as the first item in your CLASSPATH.

                Here's a UNIX example where somebody wants to use the new DatabaseManagerSwing with their older HSQLDB database, as well as with Postgresql and a local application. 

                CLASSPATH=/path/to/hsqldbutil.jar:/home/bob/myapp/classes:/usr/local/lib/pg.jdbc3.jar
export CLASSPATH
java org.hsqldb.util.DatabaseManagerSwing --urlid urlid

                DatabaseManagerSwing as an Applet

                DatabaseManagerSwing is also an applet. You can use it in HTML, JSPs, etc. Be aware that in Applet mode, actions to load or save local files will be disabled, and attempts to access any server other than the HTML-serving-host will be fail.

                Since the Applet can not store or load locally saved preferences, the only way to have persistent preference settings is by using Applet parameters.

                Brief Introduction

                Brief Introduction

                Transfer Tool is a GUI program for transferring SQL schema and data from one JDBC source to another. Source and destination can be different database engines or different databases on the same server.

                Transfer Tool works in two different modes. Direct transfer maintains a connection to both source and destination and performs the transfer. Dump and Restore mode is invoked once to transfer the data from the source to a text file (Dump), then again to transfer the data from the text file to the destination (Restore). With Dump and Restore, it is possible to make any changes to database object definitions and data prior to restoring it to the target.

                Dump and Restore modes can be set via the command line with -d (--dump) or -r (--restore) options. Alternatively the Transfer Tool can be started with any of the three modes from the Database Manager's Tools menu.

                The connection dialogue allows you to save the settings for the connection you are about to make. You can then access the connection in future sessions. These settings are shared with those from the Database Manager tool. See the appendix on Database Manager for details of the connection dialogue box.

                In version 1.8.0 Transfer Tool is no longer part of the hsqldb.jar. You can build the hsqldbutil.jar using the Ant command of the same name, to build a jar that includes Transfer Tool and the Database Manager.

                When collecting meta-data, Transfer Tool performs SELECT * FROM <table> queries on all the tables in the source database. This may take a long time with some database engines. When the source database is HSQLDB, this means memory should be available for the result sets returned from the queries. Therefore, the memory allocation of the java process in which Transfer Tool is executed may have to be high.

                Requirements

                Hsqldb TLS Support Requirements

                • Sun Java 2.x and up. (This is probably possible with IBM's Java, but I don't think anybody has attempted to run HSQLDB with TLS under IBM's Java, and I'm sure that nobody in the HSQLDB Development Group has documented how to set up the environment).

                • If Java 2.x or 3.x, then you will need need to install JSSE. Your server and/or client will start up much slower than that of Java 4.x users. Client-side users will not be able to use the https: JDBC protocol (because the https protocol handler is not implemented in 2.x/3.x Java JSSE; if there is demand, we could work around this).

                • A JKS keystore containing a private key, in order to run a server.

                • If you are running the server side, then you'll need to run a HSQLDB Server or WebServer. It doesn't matter if the underlying database instances are new, and it doesn't matter if you are making a new Server configuration or encrypting an existing Server configuration. (You can turn encryption on and off at will).

                • You need a HSQLDB jar file that was built with JSSE present. If you got your HSQLDB 1.7.2 distribution from us, you are all set, because we build with Java 1.4 (which contains JSSE). If you build your own jar file with Java 1.3, make sure to install JSSE first.

                Encrypting your JDBC connection

                At this time, only 1-way, server-cert encryption is tested.

                Client-Side

                Just use one of the following protocol prefixes.

                Hsqldb TLS URL Prefixes

                • jdbc:hsqldb:hsqls://

                • jdbc:hsqldb:https://

                At this time, the latter will only work for clients running with Java 1.4.

                If the server you wish to connect to is using a certificate approved by your default trust keystores, then there is nothing else to do. If not, then you need to tell Java to "trust" the server cert. (It's a slight over-simplification to say that if the server certificate was purchased, then you are all set; if somebody "signed their own" certificate by self-signing or using a private ca certificate, then you need to set up trust).

                First, you need to obtain the cert (only the "public" part of it). Since this cert is passed to all clients, you could obtain it by writing a java client that dumps it to file, or perhaps by using openssl s_client. Since in most cases, if you want to trust a non-commercial cert, you probably have access to the server keystore, I'll show an example of how to get what you need from the server-side JKS keystore.

                You may already have an X509 cert for your server. If you have a server keystore, then you can generate a X509 cert like this.

                Example 7.1. Exporting certificate from the server's keystore

                    keytool -export -keystore server.store -alias existing_alias -file server.cer
                In this example, server.cer is the X509 certificate that you need for the next step.

                Now, you need to add this cert to one of the system trust keystores or to a keystore of your own. See the Customizing Stores section in JSSERefGuide.html to see where your system trust keystores are. You can put private keystores anywhere you want to. The following command will add the cert to an existing keystore, or create a new keystore if client.store doesn't exist.

                Example 7.2. Adding a certificate to the client keystore

                keytool -import -trustcacerts -keystore trust.store -alias new_alias -file server.cer

                If you are making a new keystore, you probably want to start with a copy of your system default keystore which you can find somewhere under your JAVA_HOME directory (typically jre/lib/security/cacerts for a JDK, but I forget exactly where it is for a JRE).

                Unless your OS can't stop other people from writing to your files, you probably do not want to set a password on the trust keystore.

                If you added the cert to a system trust store, then you are finished. Otherwise you will need to specify your custom trust keystore to your client program. The generic way to set the trust keystore is to set the sytem property javax.net.ssl.trustStore every time that you run your client program. For example

                Example 7.3. Specifying your own trust store to a JDBC client

                    java -Djavax.net.ssl.trustStore=/home/blaine/trust.store -jar /path/to/hsqldb.jar dest-urlid
                This example runs the program SqlTool. SqlTool has built-in TLS support, however, so, for SqlTool you can set truststore on a per-urlid basis in the SqlTool configuration file.

                N.b. The hostname in your database URL must match the Common Name of the server's certificate exactly. That means that if a site certificate is admc.com, you can not use jdbc:hsqldb:hsqls://localhost or jdbc:hsqldb:hsqls://www.admc.com:1100 to connect to it.

                If you want more details on anything, see JSSERefGuide.html on Sun's site, or in the subdirectory docs/guide/security/jsse of your Java SE docs.

                Server-Side

                Get yourself a JKS keystore containing a private key. Then set the system property javax.net.ssl.keyStore to the path to that file, and javax.net.ssl.keyStorePassword to the password of the keystore (and to the private key-- they have to be the same).

                Example 7.4. Running an Hsqldb server with TLS encryption

                    java -Djavax.net.ssl.keyStorePassword=secret  \
        -Djavax.net.ssl.keyStore=/usr/hsqldb/db/db3/server.store  \
        -cp /path/to/hsqldb.jar org.hsqldb.Server

                (This is a single command that I have broken into 2 lines using my shell's \ line-continuation feature. In this example, I'm using a server.properties file so that I don't need to give arguments to specify database instances or the server endpoint).

                Caution

                Specifying a password on the command-line is definitely not secure. It's really only appropriate when untrusted users do not have any access to your computer.

                If there is any user demand, we will have a more secure way to supply the password before long.

                JSSE

                If you are running Java 4.x, then you are all set. Java 1.x users, you are on your own (Sun does not provide a JSSE that will work with 1.x). Java 2.x and 3.x users continue...

                Go to http://java.sun.com/products/jsse/index-103.html. If you agree to the terms and meet the requirements, download the domestic or global JSSE software. All you need from the software distro is the three jar files. If you have a JDK installation, then move the 3 jar files into the directory $JAVA_HOME/jre/lib/ext. If you have a JRE installation, then move the 3 jar files into the directory $JAVA_HOME/lib/ext.

                Pretty painless.

                Making a Private-key Keystore

                There are two main ways to do this. Either you can use a certificate signed by a certificate authority, or you can make your own. One thing that you need to know in both cases is, the Common Name of the cert has to be the exact hostname that JDBC clients will use in their database URL.

                CA-Signed Cert

                I'm not going to tell you how to get a CA-signed SSL certificate. That is well documented at many other places.

                Assuming that you have a standard pem-style private key certificate, here's how you can use openssl and the program DERImport to get it into a JKS keystore.

                Because I have spent a lot of time on this document already, I am just giving you an example.

                Example 7.5. Getting a pem-style private key into a JKS keystore

                openssl pkcs8 -topk8 -outform DER -in Xpvk.pem -inform PEM -out Xpvk.pk8 -nocrypt

openssl x509 -in Xcert.pem -out Xcert.der -outform DER

java DERImport new.keystore NEWALIAS Xpvk.pk8 Xcert.der

                Important

                Make sure to set the password of the key exactly the same as the password for the keystore!

                You need the program DERImport.class of course. Do some internet searches to find DERImport.java or DERImport.class and download it.

                If DERImport has become difficult to obtain, I can write a program to do the same thing-- just let me know.

                Non-CA-Signed Cert

                Run man keytool or see the Creating a Keystore section of JSSERefGuide.html.

                Automatic Server or WebServer startup on UNIX

                If you are on UNIX and want to automatically start and stop a Server or WebServer running with encryption, follow the instructions in the UNIX Quick Start chapter, and remember to make the init script configuration file readable only to root and to set the variables TLS_PASSWORD and TLS_KEYSTORE.

                If you are using a private server certificate, make sure to also set the trust store filepath as shown in the sample init script configuration file.

                The cautionary warning above still applies. The password will be visible to any minimally competent local UNIX user who wants to see it.

                Purpose

                This chapter explains how to quickly install, run, and use HSQLDB on UNIX.

                HSQLDB has lots of great optional features. I intend to cover very few of them. I do intend to cover what I think is the most common UNIX setup: To run a multi-user database with permament data persistence. (By the latter I mean that data is stored to disk so that the data will persist across database shutdowns and startups). I also cover how to run HSQLDB as a system daemon.

                Installation

                Go to http://sourceforge.net/projects/hsqldb and click on the "files" link. You want the current version. This will be the highest numbered version under the plain black "hsqldb" heading. See if there's a distribution for the current HSQLDB version in the format that you want.

                If you want an rpm, you should still find out the current version of HSQLDB as described in the previous paragraph. Then click "hsqldb" in the "free section" of http://www.jpackage.org/ and see if they have the current HSQLDB version built yet. Hopefully, the JPackage folk will document what JVM versions their rpm will support (currently they document this neither on their site nor within the package itself). (I really can't document how to download from a site that is totally beyond my control).

                Note

                It could very well happen that some of the file formats which I discuss below are not in fact offered. If so, then we have not gotten around to building them.

                Binary installation depends on the package format that you downloaded.

                Installing from a .pkg.Z file

                This package is only for use by a Solaris super-user. It's a System V package. Download then uncompress the package with uncompress or gunzip 

                    uncompress filename.pkg.Z
                You can read about the package by running 
                    pkginfo -l -d filename.pkg
                Run pkgadd as root to install. 

                    pkgadd -d filename.pkg
                Installing from a .rpm file

                This is a Linux rpm package. After you download the rpm, you can read about it by running 

                    rpm -qip /path/to/file.rpm

                Rpms can be installed or upgraded by running 

                    rpm -Uvh /path/to/file.rpm
                as root. Suse users may want to keep Yast aware of installed packages by running rpm through Yast: yast2 -i /path/to/file.rpm.

                Installing from a .zip file

                Extract the zip file to the parent directory of the new HSQLDB home. You don't need to create the HSQLDB_HOME directory because the extraction will create it for you with the right name) 

                    cd parent/of/new/hsqldb/home
    unzip /path/to/file.zip

                All the files in the zip archive will be extracted to underneath a new hsqldb directory.

                Take a look at the files you installed. (Under hsqldb for zip file installations. Otherwise, use the utilities for your packaging system). The most important file of the hsqldb system is hsqldb.jar, which resides in the directory lib.

                Important

                For the purposes of this chapter, I define HSQLDB_HOME to be the parent directory of the lib directory that contains hsqldb.jar. E.g., if your path to hsqldb.jar is /a/b/hsqldb/lib/hsqldb.jar, then your HSQLDB_HOME is /a/b/hsqldb.

                If the description of your distribution says that the hsqldb.jar file will work for your Java version, then you are finished with installation. Otherwise you need to build a new hsqldb.jar file.

                If you followed the instructions above and you still don't know what Java version your hsqldb.jar supports, then read HSQLDB_HOME/readme.txt and HSQLDB_HOME/index.html. If that still doesn't help, then you can just try your hsqldb.jar and see if it works, or build your own.

                To use the supplied hsqldb.jar, just skip to the next section of this document. Otherwise build a new hsqldb.jar.

                Procedure 3.1. Building hsqldb.jar

                1. If you don't already have Ant, download the latest stable binary version from http://ant.apache.org. cd to where you want Ant to live, and extract from the archive with 

                      unzip /path/to/file.zip
                  or
                      tar -xzf /path/to/file.tar.gz
                  or
                      bunzip2 -c /path/to/file.tar.bz2 | tar -xzf -
                  Everything will be installed into a new subdirectory named apache-ant- + version. You can rename the directory after the extraction if you wish.

                2. Set the environmental variable JAVA_HOME to the base directory of your Java JRE or SDK, like 

                      export JAVA_HOME; JAVA_HOME=/usr/java/j2sdk1.4.0
                  The location is entirely dependent upon your variety of UNIX. Sun's rpm distributions of Java normally install to /usr/java/something. Sun's System V package distributions of Java (including those that come with Solaris) normally install to /usr/something, with a sym-link from /usr/java to the default version (so for Solaris you will usually set JAVA_HOME to /usr/java).

                3. Remove the existing file HSQLDB_HOME/lib/hsqldb.jar.

                4. cd to HSQLDB_HOME/build. Make sure that the bin directory under your Ant home is in your search path. Run the following command. 

                      ant hsqldb
                  This will build a new HSQLDB_HOME/lib/hsqldb.jar.

                See the Building HSQLDB appendix if you want to build anything other than hsqldb.jar with all default settings.

                Setting up a Hsqldb Persistent Database Instance and a Hsqldb Server

                If you installed from an OS-specific package, you may already have a database instance and server pre-configured. See if your package includes a file named server.properties (make use of your packaging utilities). If you do, then I suggest that you still read this section while you poke around, in order to understand your setup.

                1. Select a UNIX user to run the database as. If this database is for the use of multiple users, or is a production system (or to emulate a production system), you should dedicate a UNIX user for this purpose. In my examples, I use the user name hsqldb. In this chapter, I refer to this user as the HSQLDB_OWNER, since that user will own the database instance files and processes.

                  If the account doesn't exist, then create it. On all system-5 UNIXes and most hybrids (including Linux), you can run (as root) something like 

                      useradd -c 'HSQLDB Database Owner' -s /bin/bash -m hsqldb
                  (BSD-variant users can use a similar pw useradd hsqldb... command).

                2. Become the HSQLDB_OWNER. Copy the sample file HSQLDB_HOME/src/org/hsqldb/sample/sample-server.properties to the HSQLDB_OWNER's home directory and rename it to server.properties. 

                  # Hsqldb Server cfg file.
# See the Advanced Topics chapter of the Hsqldb User Guide.

server.database.0   file:db0/db0
# I suggest that, for every file: database you define, you add the
# connection property "ifexists=true" after the database instance
# is created (which happens simply by starting the Server one time).
# Just append ";ifexists=true" to the file: URL, like so:
# server.database.0   file:db0/db0;ifexists=true

                  Since the value of the first database (server.database.0) begins with file:, the database instance will be persisted to a set of files in the specified directory with names beginning with the specified name. Set the path to whatever you want (relative paths will be relative to the directory containing the properties file). You can read about how to specify other database instances of various types, and how to make settings for the listen port and many other things, in the Advanced Topics chapter.

                3. Set and export the environmental variable CLASSPATH to the value of HSQLDB_HOME (as described above) plus "/lib/hsqldb.jar", like 

                      export CLASSPATH; CLASSPATH=/path/to/hsqldb/lib/hsqldb.jar
                  In HSQLDB_OWNER's home directory, run

                      nohup java org.hsqldb.Server &

                  This will start the Server process in the background, and will create your new database instance "db0". Continue on when you see the message containing HSQLDB server... is online. nohup just makes sure that the command will not quit when you exit the current shell (omit it if that's what you want to do).

                Accessing your Database

                Copy the file HSQLDB_HOME/src/org/hsqldb/sample/sqltool.rc to the HSQLDB_OWNER's home directory. Use chmod to make the file readable and writable only to HSQLDB_OWNER. 

                # $Id: sqltool.rc,v 1.22 2007/08/09 03:22:21 unsaved Exp $

# This is a sample RC configuration file used by SqlTool, DatabaseManager,
# and any other program that uses the org.hsqldb.util.RCData class.

# You can run SqlTool right now by copying this file to your home directory
# and running
#    java -jar /path/to/hsqldb.jar mem
# This will access the first urlid definition below in order to use a 
# personal Memory-Only database.
# "url" values may, of course, contain JDBC connection properties, delimited
# with semicolons.

# If you have the least concerns about security, then secure access to

# In the great majority of cases, you want to use the file classes12.zip
# (which you can get from the directory $ORACLE_HOME/jdbc/lib of any
# Oracle installation compatible with your server).
# Since you need to add to the classpath, you can't invoke SqlTool with
# the jar switch, like "java -jar .../hsqldb.jar..." or 
# "java -jar .../hsqlsqltool.jar...".
# Put both the HSQLDB jar and classes12.zip in your classpath (and export!)
# and run something like "java org.hsqldb.util.SqlTool...".

# would be).

# The embedded Derby driver requires derby.jar.
# There'a also the org.apache.derby.jdbc.ClientDriver driver with URL
# like jdbc:derby://<server>[:<port>]/databaseName, which requires
# derbyclient.jar.
# You can use \= to commit, since the Derby team decided (why???)
# not to implement the SQL standard statement "commit"!!
# Note that SqlTool can not shut down an embedded Derby database properly,
# since that requires an additional SQL connection just for that purpose.
# However, I've never lost data by not shutting it down properly.
# Other than not supporting this quirk of Derby, SqlTool is miles ahead of ij.

                We will be using the "localhost-sa" sample urlid definition from the config file. The JDBC URL for this urlid is jdbc:hsqldb:hsql://localhost. That is the URL for the default database instance of a HSQLDB Server running on the default port of the local host. You can read about URLs to connect to other instances and other servers in the Advanced Topics chapter.

                Run SqlTool. 

                    java -jar path/to/hsqldb.jar localhost-sa
                If you get a prompt, then all is well. If security is of any concern to you at all, then you should change the privileged password in the database. Use the command SET PASSWORD command to change SA's password. 
                    set password "newpassword";

                When you're finished playing, exit with the command \q.

                If you changed the SA password, then you need to fix the password in the sqltool.rc file accordingly.

                You can, of course, also access the database with any JDBC client program. See the First JDBC Client Example appendix. You will need to modify your classpath to include hsqldb.jar as well as your client class(es). You can also use the other HSQLDB client programs, such as org.hsqldb.util.DatabasManagerSwing, a graphical client with a similar purpose to SqlTool.

                You can use any normal UNIX account to run the JDBC clients, including SqlTool, as long as the account has read access to the hsqldb.jar file and to an sqltool.rc file. See the SqlTool chapter about where to put sqltool.rc, how to execute sql files, and other SqlTool features.

                Create additional Accounts

                Connect to the database as SA (or any other Administrative user) and run CREATE USER to create new accounts for your database instance. HSQLDB accounts are database-instance-specific, not Server-specific.

                For the current version of HSQLDB, only users with Role of DBA may create or own database objects. DBA members have privileges to do anything. Non-DBAs may be granted some privileges, but may never create or own database objects. (Before long, non-DBAs will be able to create objects if they have permission to do so in the target schema). When you first create a hsqldb database, it has only one database user-- SA, a DBA account, with an empty string password. You should set a password (as described above). You can create as many additional users as you wish. To make a user a DBA, you can use the "ADMIN" option to the CREATE USER command, or GRANT the DBA Role to the account after creating it.

                If you create a user without the ADMIN tag (and without granting the DBA role to them) this user will be able to read the data dictionary tables, but will be able unable to create or own his own objects. He will have only the rights which the pseudo-user PUBLIC has. To give him more permissions, even rights to read objects, you can GRANT permissions for specific objects, grant Roles (which encompass a set of permissions), or grant the DBA Role itself.

                Since only people with a database account may do anything at all with the database, it is often useful to permit other database users to view the data in your tables. To optimize performance, reduce contention, and minimize administration, it is often best to grant SELECT to PUBLIC on any object that needs to be accessed by multiple database users (with the significant exception of any data which you want to keep secret).

                Shutdown

                Do a clean database shutdown when you are finished with the database instance. You need to connect up as SA or some other Admin user, of course. With SqlTool, you can run 

                    java -jar path/to/hsqldb.jar --sql shutdown localhost-sa
                You don't have to worry about stopping the Server because it shuts down automatically when all served database instances are shut down.

                Running Hsqldb as a System Daemon

                You can, of course, run HSQLDB through inittab on System V UNIXes, but usually an init script is more convenient and manageable. This section explains how to set up and use our UNIX init script. Our init script is only for use by root. (That is not to say that the Server will run as root-- it usually should not).

                The main purpose of the init script is to start up a Server with the database instances specified in your server.properties file; and to shut down all of those instances plus additional urlids which you may (optionally) list in your init script config file. These urlids must all have entries in a sqltool.rc file. If, due to firewall issues, you want to run a WebServer instead of a Server, then make sure you have a healthy WebServer with a webserver.properties set up, adjust your URLs in sqltool.rc, and set TARGET_CLASS in the config file. (By following the commented examples in the config file, you can start up any number of Server and/or WebServer listeners with or without TLS ecryption).

                After you have the init script set up, root can use it anytime to start or stop HSQLDB. (I.e., not just at system bootup or shutdown).

                Portability of hsqldb init script

                The primary design criterion of the init script is portability. It does not print pretty color startup/shutdown messages as is common in late-model Linuxes and HPUX; and it does not keep subsystem state files or use the startup/shutdown functions supplied by many UNIXes, because these features are all non-portable.

                Offsetting these limitations, this one script does it's intended job great on the UNIX varieties I have tested, and can easily be modified to accommodate other UNIXes. While you don't have tight integration with OS-specific daemon administration guis, etc., you do have a well tested and well behaved script that gives good, utilitarian feedback.

                Init script Setup Procedure

                The strategy taken here is to get the init script to run your single Server or WebServer first (as specified by TARGET_CLASS). After that's working, you can customize the JVM that is run by running additional Servers in it, running your own application in it (embedding), or even overriding HSQLDB behavior with your own overriding classes.

                1. Copy the init script hsqldb from HSQLDB_HOME/bin into the directory where init scripts live on your variety of UNIX. The most common locations are /etc/init.d or /etc/rc.d/init.d on System V style UNIXes, /usr/local/etc/rc.d on BSD style UNIXes, and /Library/StartupItems/hsqldb on OS X (you'll need to create the directory for the last).

                2. Look at the comment towards the top of the init script which lists recommended locations for the configuration file for various UNIX platforms. Copy the sample config file HSQLDB_HOME/src/org/hsqldb/sample/sample-hsqldb.cfg to one of the listed locations (your choice). Edit the config file according to the instructions in it. 

                  # $Id: sample-hsqldb.cfg,v 1.16 2005/07/24 18:33:13 unsaved Exp $

# Sample configuration file for HSQLDB database server.
# See the "UNIX Quick Start" chapter of the Hsqldb User Guide.

# N.b.!!!!  You must place this in the right location for your type of UNIX.
# See the init script "hsqldb" to see where this must be placed and
# what it should be renamed to.

# This file is "sourced" by a Bourne shell, so use Bourne shell syntax.

# This file WILL NOT WORK until you set (at least) the non-commented
# variables to the appropriate values for your system.
# Life will be easier if you avoid all filepaths with spaces or any other
# funny characters.  Don't ask for support if you ignore this advice.

JAVA_EXECUTABLE=/usr/bin/java

# Unless you copied a hsqldb.jar file from another system, this typically
# resides at $HSQLDB_HOME/lib/hsqldb.jar, where $HSQLDB_HOME is your HSQLDB
# software base directory.
HSQLDB_JAR_PATH=/opt/hsqldb/lib/hsqldb.jar

# Where the file "server.properties" resides.
SERVER_HOME=/opt/hsqldb/data

# What UNIX user the server will run as.
# (The shutdown client is always run as root or the invoker of the init script).
# Runs as root by default, but you should take the time to set database file
# ownerships to another user and set that user name here.
HSQLDB_OWNER=hsqldb

# The HSQLDB jar file specified in HSQLDB_JAR_PATH above will automatically
# be in the class path.  This arg specifies additional classpath elements.
# To embed your own application, add your jar file(s) or class base
# directories here, and add your main class to the INVOC_ADDL_ARGS setting
# below.
#SERVER_ADDL_CLASSPATH=/usr/local/dist/currencybank.jar

# We require all Server/WebServer instances to be accessible within 
# $MAX_START_SECS from when the Server/WebServer is started.
# Defaults to 60.
# Raise this is you are running lots of DB instances or have a slow server.
#MAX_START_SECS=200

# Time to allow for JVM to die after all HSQLDB instances stopped.
# Defaults to 1.
#MAX_TERMINATE_SECS=0

# These are "urlid" values from a SqlTool authentication file
# ** IN ADDITION TO THOSE IN YOUR server.properties OR webserver.properties **
# file.  All server.urlid.X values from your properties file will automatically
# be started/stopped/tested.  $SHUTDOWN_URLIDS is for additional urlids which
# will stopped.  (Therefore, most users will not set this at all).
# Separate multiple values with white space.  NO OTHER SPECIAL CHARACTERS!
# Make sure to quote the entire value if it contains white space separator(s).
# Defaults to none (i.e., only urlids set in properties file will be stopped).
#SHUTDOWN_URLIDS='sa mygms'

# SqlTool authentication file used only for shutdown.
# The default value will be sqltool.rc in root's home directory, since it is 
# root who runs the init script.
# (See the SqlTool chapter of the HSQLDB User Guide if you don't understand 
# this).
#AUTH_FILE=/home/blaine/sqltool.rc

# Set this to either 'WebServer' or 'Server'.  Defaults to Server.
# The JVM that is started can invoke many classes (see the following item
# about that), but this is the Server that is used (1) to check status,
# (2) to shut down the JVM, (3) to get urlids for #1 from the 
# server's server/webserver.properties file.
#TARGET_CLASS=WebServer
# Note that you don't specify the org.hsqldb package, since you have no 
# choice in the matter (you can only run org.hsqldb.Server or 
# org.hsqldb.WebServer).  If you specify additional classes with
# INVOC_ADDL_ARGS (described next), you do need to specify the
# full class name with package name.

# This is where you specify exactly what your HSQLDB JVM will run.
# The class org.hsqldb.util.MainInvoker will run the TARGET_CLASS
# specified above with any arguments supplied here + any other classes
# and arguments.  Every additional class (in addition to the TARGET_CLASS)
# must be preceded with an empty string, so that MainInvoker will know
# you are giving a class name.  MainInvoker will invoke the normal 
# static main(String[]) method of each such class.  
# By default, MainInvoker will just run TARGET_CLASS with no args.
# Example that runs just the TARGET_CLASS with the specified arguments:
#INVOC_ADDL_ARGS='-silent false'
# Example that runs the TARGET_CLASS plus a WebServer:
#INVOC_ADDL_ARGS='"" org.hsqldb.WebServer'
# Note the empty string preceding the class name.
# Example that starts TARGET_CLASS with an argument + a WebServer +
# your own application with its args (i.e., the HSQLDB Servers are
# "embedded" in your application).  (Set SERVER_ADDL_CLASSPATH too).:
#INVOC_ADDL_ARGS='-silent false "" org.hsqldb.WebServer "" com.acme.Stone --env prod localhost'
# Example to run a non-TLS server in same JVM with a TLS server.  In this
# case, TARGET_CLASS is Server which will run in TLS mode by virtue of 
# setting TLS_KEYSTORE and TLS_PASSWORD above.  The "additional" Server
# here overrides the 'tls' and 'port' settings:
#INVOC_ADDL_ARGS="'' org.hsqldb.Server -port 9002 -tls false"
# Note that you use nested quotes to group arguments and to specify the
# empty-string delimiter.

# For TLS encryption for your Server, set these two variables.
# N.b.:  If you set these, then make this file unreadable to non-root users!!!!
# See the TLS chapter of the HSQLDB User Guide, paying attention to the 
# security warning(s).
# If you are running with a private server cert, then you will also need to 
# set "truststore" in the your SqlTool config file (location is set by the
# AUTH_FILE variable in this file, or it must be at the default location for 
# HSQLDB_OWNER).
#TLS_KEYSTORE=/path/to/jks/server.store
#TLS_PASSWORD=password

# Any JVM args for the invocation of the JDBC client used to verify DB
# instances and to shut them down (SqlToolSprayer).
# This example specifies the location of a private trust store for TLS 
# encryption.
# For multiple args, put quotes around entire value.
#CLIENT_JVMARGS=-Djavax.net.debug=ssl

# Any JVM args for the server.
# For multiple args, put quotes around entire value.
#SERVER_JVMARGS=-Xmx512m

                3. Either copy HSQLDB_OWNER's sqltool.rc file into root's home directory, or set the value of AUTH_FILE to the absolute path of HSQLDB_OWNER's sqltool.rc file. This file is read (for stops) directly by root, even if you run hsqldb as non-root (by setting HSQLDB_OWNER in the config file). If you copy the file, make sure to use chmod to restrict permissions on the new copy. (The init script now enforces permissions on this file).

                4. Edit your server.properties file. For every server.database.X that you have defined, set a property of name server.urlid.X to the urlid for an Administrative user for that database instance.

                  Example 3.1. server.properties fragment

                      server.database.0=file://home/hsqldb/data/db1
    server.urlid.0=localhostdb1

                  Warning

                  Make sure to add a urlid for each and every database instance. If you don't then the init script will never know about databases that become inaccessible and will give false diagnostics.

                  For this example, you would need to define the urlid localhostdb1 in your sqltool.rc file.

                  Example 3.2. example sqltool.rc stanza

                      urlid localhostdb1
    url jdbc:hsqldb:hsql://localhost
    username sa
    password secret

                5. Verify that the init script works.

                  Just run 

                      /path/to/hsqldb
                  as root to see the arguments you may use. Notice that you can run 

                      /path/to/hsqldb status

                  at any time to see whether your HSQLDB Server is running.

                  Re-run the script with each of the possible arguments to really test it good. If anything doesn't work right, then see the Troubleshooting the Init Script section.

                6. Tell your OS to run the init script upon system startup and shutdown. If you are using a UNIX variant that has /etc/rc.conf or /etc/rc.conf.local (like BSD variants and Gentoo), you must set "hsqldb_enable" to "YES" in either of those files. (Just run cd /etc; ls rc.conf rc.conf.local to see if you have one of these files). For good UNIXes that use System V style init, you must set up hard links or soft links either manually or with management tools (such as chkconfig or insserv) or Gui's (like run level editors).

                  This paragraph is for Mac OS X users only. If you followed the instructions above, your init script should reside at /Library/StartupItems/hsqldb/hsqldb. Now copy the file StartupParameters.plist from the directory src/org.hsqldb/sample of your HSQLDB distribution to the same directory as the init script. As long as these two files reside in /Library/StartupItems/hsqldb, your init script is active (for portability reasons, it doesn't check for a setting in /etc/hostconfig). You can run it as a Startup Item by running 

                      SystemStarter {start|stop|restart} Hsqldb
                  Hsqldb is the service name. See the man page for SystemStarter. To disable the init script, wipe out the /Library/StartupItems/hsqldb directory. Hard to believe, but the Mac people tell me that during system shutdown the Startup Items don't run at all. Therefore, if you don't want your data corrupted, make sure to run "SystemStarter stop Hsqldb" before shutting down your Mac.

                Follow the examples in the config file to add additional classes to the server JVM's classpath and to execute additional classes in your JVM. (See the SERVER_ADDL_CLASSPATH and INVOC_ADDL_ARGS items).

                Troubleshooting the Init Script

                Do a ps to look for processes containing the string hsqldb, and try to connect to the database from any client. If the init script starts up your database successfully, but incorrectly reports that it has not, then your problem is with specification of urlid(s) or SqlTool setup. If your database really did not start, then skip to the next paragraph. Verify that the urlid(s) listed in the server.properties or webserver.properties are correct. and verify that you can run SqlTool as root to connect to the instances. (For the latter test, use the --rcfile switch if you are setting AUTH_FILE in the init script config file).

                If your database really is not starting, then verify that you can su to the database owner account and start the database. The command su USERNAME -c ... won't work on most UNIXes unless the target user has a real login shell. Therefore, if you try to tighten up security by disabling this user's login shell, you will break the init script. If these possibilities don't pan out, then debug the init script or seek help, as described below.

                To debug the init script, run it in verbose mode to see exactly what is happening (and perhaps manually run the steps that are suspect). To run an init script (in fact, any sh shell script) in verbose mode, use sh with the -x or -v switch, like 

                    sh -x path/to/hsqldb start
                See the man page for sh if you don't know the difference between -v and -x.

                If you want troubleshooting help, use the HSQLDB lists/forums or email me at blaine.simpson@admc.com. If you email me, make sure to include the revision number from your hsqldb init script (it's towards the top in the line that starts like "# $Id:"), and the output of a run of 

                    sh -x path/to/hsqldb start > /tmp/hstart.log 2>&1

                Setting up OpenOffice.org

                On Linux

                Introduction

                HSQLDB can now act as a Database with OpenOffice.org. This document is written to help you connecting and running HSQLDB out of OpenOffice.org in a simple way. Without user-managment and only for your single-system.

                If you have problems read the other available documents, because I will not write them here again. If you need a real DB-System with user-management and different rights for different users, read the other documents.

                HSQLDB is included with OpenOffice.org 2.0 and is used by default. Please refer to standard OpenOffice.org 2.0 documentation on how to use HSQLDB with this version.

                Installing

                I assume you have a running OpenOffice.org (OOo) and a JavaRuntimeEnvironment. So place the hsqldb_*.zip file where you want on your disk and unpack it (I assume you have done this already).

                Setting up OpenOffice.org

                Start OOo with a text document and go to the Database-Explorer (simply by pressing F4). In the left frame you see a tree-view with all known databases in OOo.

                A right mouse-click opens a menu where you can manage your databases. So click on New Database and choose a name that you want to have inside OOo. I chose HSQLDB as name.

                As connection-type choose JDBC and then switch to the JDBC-tab.

                As Driver-Class insert org.hsqldb.jdbcDriver and as URL choose the following:

                On Windows

                You can specify a directory where HSQLDB should store the info and data. Something like jdbc:hsqldb:file:c:\javasrc\hsqldb-dev\databasename (where jdbc: is written by OOo). The string c:\javasrc\hsqldb-dev\databasename works only on windows, but you can write this down as linux-path like /javasrc/hsqldb-dev/databasename too. Then HSQLDB takes the c:\ drive as root. This means this works only on c:\ for you.

                The first is the directory-path and the databasename is the identifier for the database.

                On Linux

                Choose a path as said for windows like /opt/db/data

                As username take sa, this is the standard-administrator for HSQLDB.

                Now click the OK-Button

                Now OOo has to find your hsqldb.jar file. So go to options => security and insert the path to the .jar file. If you have problems, search the Online-help for JDBC. You then get help in your own language (this is generally quite better than my English, I think ;-)

                If you cannot write to your Tables, OOo thinks that you don't have permission to write to HSQLDB. Then we tell OOo to ignore the DriverPrivileges because on our single-user-system we do not need them.

                Because OOo is working on this, the next Step is only needed for systems without write - permission.

                So we go to http://dba.openoffice.org and look at the IgnoreDriverPrivileges.html file in the HowTo-section. You find here a macro-code.

                Open tools => macro in OOo to get the Basic-IDE. Here simple copy and paste the code and run the macro. You see a input-box where you only have to insert the name of your DB, in my example I have to insert HSQLDB, because I took this as name in OOo.

                Note that if you change your OOo-DB name, you have to run this macro again!

                Now we only have to stop and restart OOo. Be sure that you exit Quickstarter and all running processes too. On next OOo-Start you should have a running Database in OpenOffice.org.

                Appendix E. Hsqldb Test Utility

                $Date: 2005/05/27 12:41:50 $

                The org.hsqldb.test package contains a number of tests for various functions of the database engine. Among these, the TestSelf class performs the tests that are based on scripts. To run the tests, you should compile the hsqldbtest.jar target with Ant.

                For TestSelf, a batch file is provided in the testrun/hsqldb directory, together with a set of TestSelf*.txt files. To start the application in Windows, change to the directory and type:

                    runtest TestSelf

                In Unix / Linux, type:

                    ./runTest.sh TestSelf

                The new version of TestSelf runs multiple SQL test files to test different SQL operations of the database. All files in the working directory with names matching TestSelf*.txt are processed in alphabetical order.

                You can add your own scripts to test different series of SQL queries. The format of the TestSelf*.txt file is simple text, with some indentation and prefixes in the form of Java-style comments. The prefixes indicate what the expected result should be.

                • Comment lines must start with -- and are ignored

                • Lines starting with spaces are the continuation of the previous line

                • SQL statements with no prefix are simply executed.

                • The remaining items in this list exemplify use of the available command line-prefixes.

                • The /*s*/ option stands for silent. It is used for executing quries regardless of results. Used for preparation of tests, not for actual tests.

                  /*s*/ Any SQL statement - errors are ignored

                • The /*c<rows>*/ option is for SELECT queries and asserts the number of rows in the result matches the given count.

                  /*c<rows>*/ SQL statement returning count of <rows>

                • The /*u*/ option is for queries that return an update count, such as DELETE and UPDATE. It asserts the update count matches.

                  /*u<count>*/ SQL statement returning an update count equal to <count>

                • The /*e*/ option asserts that the given query results in an erros. It is mainly used for testing the error detection capabilities of the engine. It can also be used with syntactically valid queries to assert a certain state in the database. For example a CREATE TABLE can be used to assert the table of the same name already exists.

                  /*e*/ SQL statement that should produce an error when executing

                • The /*r....*/ option asserts the SELECT query returns a single row containing the given set of field values.

                  /*r<string1>,<string2>*/ SQL statement returning a single row ResultSet equal to the specified value

                • The extended /*r...*/ option asserts the SELECT query returns the given rows containing the given set of field values.

                  /*r
    <string1>,<string2>
    <string1>,<string2>
    <string1>,<string2>
*/ SQL statement returning a multiple row ResultSet equal to the specified values

                  (note that the result set lines are indented).

                • All the options are lowercase letters. During development, an uppercase can be used for a given test to exclude a test from the test run. The utility will just report the test blocks that have been excluded without running them. Once the code has been developed, the option can be turned into lowercase to perform the actual test.

                See the TestSelf*.txt files in the /testrun/hsqldb/ directory for actual examples.

                ANNOUNCEMENTS OF SOME ADDITIONAL SOFTWARE THAT CAN POSSIBLY BE USED WITH HSQLDB

                 

                This document is a compilation of some information that has been submitted to HSQLDB mailing lists or forums. The HSQLDB project or its developers are not responsible for the software mentioned in this document, its suitability for any purpose, or the accuracy of the information provided in this document.

                LightCrypto is a set of Open Source Java
                classes with basic cryptographic routines using the BouncyCastle lightweight API.

                It uses a minimal amount of memory so it can be used with J2ME, browser applets, on small Java devices such as PDA's or Java enabled mobile phones or in any other situation where Sun's JCE (Java Cryptographic
                Extensions) is too heavy for the job.

                Hsqldb-ready functions are also included.

                Feature list:

                # Create digest from strings and files with MD5 (default), SHA-1, SHA-256 , SHA-512 or RIPEMD160 hash algorithms
                # Encrypt/Decrypt strings and files using the AES (lightweight implementation) algorithm with any keylength (default 128 bits) in CBC mode with PKCS12 padding.

                Beta 1 (including HSqldb routines + examples) has been released and can be downloaded on
                http://sourceforge.net/project/showfiles.php?group_id=60642

                The open-source FormattedDataSet may be the easiest way to generate dynamic text such as HTML, and XML.

                I just deployed a demo WAR that allows developers to enter any hsqldb join and render the results as an HTML table that can be sorted by clicking on the column headers. I picked hsqldb for my database as I didn't want anyone that installed the war to have to worry about installing a database.

                The demo also times opening/closing Connections, ResultSets and Statements. This WAR would be useful for you guys to give out to demonstrate your database.

                The demo works with any RDBMS.

                Check it out at http://www.fdsapi.com and select the live demo link.

                Parameters:
                e - an ActionEvent value is been sent to ZaurusEditor as ActionListener

                The possible events are:

                • Buttons on the search panel:
                  Search Row
                  Starts the search of rows in the choosen table with the given search words and search options. Without any search words, all rows will be found.
                  If no row meets the criteria, there will be a message in the status line.
                  New Row
                  An empty input panel for the choosen table is given. Any search words are ignored.
                • Buttons on the edit panel:
                  Any changes to field values on this panel will be updated to the table when the actual row is left, i. e. when pressing one of the buttons 'Prev', 'Next' or 'Search'.
                  Cancel
                  Any changes to field contents are canceled and reset to the previous values.
                  Prev
                  Show the previous row which meets the search criteria.
                  Next
                  Show the next row which meets the search criteria.
                  Delete
                  This button has to be clicked twice and the shown row will be deleted from the table
                  Search
                  With this button a new search is initiated. Any changes made to field contents are saved
                • Buttons on the insert panel:
                  Cancel Insert
                  After beginning to fill a new row, the insert may be cancelled. The search panel will be shown next.
                  New Insert
                  The new row is inserted into the table and a new empty insert panel is shown.
                  New Search
                  The new row is inserted into the table and the search panel is shown again.
                o refresh 
                 public void refresh(Connection c)
                refresh will read again the meta data of the actual database. This is useful after changes of the table structures for instance creating or dropping tables, or altering tabel. The method will be called if one asks to refresh the tree or if the connection to the database is changed.

                Parameters:
                c - a Connection is the actual connection to the database

                Building HSQL Database for Sharp

                Get the actual version of HSQLDB at sourceforge.net

                For version 1.7.1, you need Ant Ant and a Java Development Kit 1.1. Version 1.7.2 should be compiled with JKD 1.3.1.

                Go to the directory $HSQLDB/build/ and build the jar-file for Sharp Zaurus with the command

                ant jarzaurus

                The directory subtree $HSQLDB/build/packaging/zaurus/package/ contains the necessary directories and files to build an ipkg-package for Sharp Zaurus on a Linux system. Make the ipkg-package by submitting the following command in the directory $HSQLDB/build/packaging/zaurus/

                makePackage

                HSQL Database for Sharp

                HSQLDB is a relational database engine written in Java, with a JDBC driver, supporting a subset of ANSI-92 SQL. It is a small, fast database engine supporting both in-memory and disk-based tables. This product includes Hypersonic SQL.

                For more information about HSQLDB visit sourceforge.net

                HSQLDB for Sharp Zaurus S-5500 contains a Database Manager with the following functions:

                • Inspecting all tables and columns of a database in a tree view.
                • Editing and executing any SQL statement.
                • Loading and saving of SQL scripts.
                • Using simple forms for each table for searching, editing or deleting rows. The forms are automatically generated and respect referential integrity.

                For further information look at

                Further enhancements of HSQL Database Manager for Sharp

                I have some ideas for more functions for the HSQL Database Manager for Sharp Zaurus. Please send me your feedback. Tell me about your needs or vote for ideas in the following list:

                • More specific entry fields for easier input of data. For instance:
                  • a date field with a pop-up window which shows the days of the week
                  • a memo field with an own panel for long notes and text
                • a graphical view: starting with an arbitrary result table in the result panel, this function would look for numerical data and would try to draw a graphical representation. For instance: a table holding the quotes of one or more share for differents dates, a table with the fuel consumption of a car in different months etc.
                • Default values for new rows: the possibility to define for specific columns default values like max(value)+1, last value, actual date etc. which are used when you want to type new rows.

                Index

                Using HSQL Database Manager for Sharp

                The main functions of the HSQL DatabaseManager for Zaurus are

                There are four different panels which may be chosen from the 'View' menu or with one of the four buttons under the menu:

                1. Tree
                2. Command
                3. Result
                4. Editor

                Starting HSQLDB.

                HSQLDB for Zaurus is started with the appropriate icon , usally located under the Jeode tab. By default, a database called 'test' is opened and the tables in this database are displayed in the tree panel.

                To get an impression of the functionalty, insert some test data by selecting the appropriate point in the 'Options' menu.

                Connecting to a database

                To open a different database, select 'Connect' from the 'File' menu. Select 'HSQL Standalone' as type, and replace the database name 'test' in the URL with a different name.

                If you want to use a different database system (usually on your desktop) you need the appropriate JDBC driver for that system.

                Executing scripts

                You may save and open scripts with the appropriate functions in the 'File' menu. A script consists of one or more valid SQL statements. For example, you may save often-used SQL queries on your tables. If a script is opened, it is shown in the command panel and can be executed from there.

                Tree panel

                The tree panel shows all the tables in the connected database. Use the plus signs to expand the tree. For each table there is a list of the columns with their data type.

                Command panel

                The command panel is used to edit any SQL statement. Use 'Save Script' in the 'File' menu to save the SQL statement.

                The SQL command is executed by clicking on the 'Execute' button at the bottom of the command panel, or by pressing Shift+Enter or Ctrl+Enter. The result is shown in the result panel.

                Any executed SQL statement may be re-loaded to the command panel by selecting from the 'Recent' menu.

                Result panel

                The result of an executed SQL statement is shown in the result panel. In the 'View' menu, you can choose between a text view or a grid view of the result rows.

                If you select an SQL statement from the 'SQL' menu, the keyword is pasted into the command panel and the syntax of that SQL statement is shown in the result panel.

                Editor panel

                The editor shows different forms:

                • a search form
                • an entry form for every table in the database

                Search form

                The editor comes up with a search form where you can select

                • the table that should be searched through,
                • one or more words (or numbers) that should be searched for,
                • whether the rows that are searched contain all or just one search word,
                • whether the case of the search word should be respected,
                • whether the search words can be a part of a column or should match the whole column.

                When clicking on the 'Search Rows' button, all rows of the chosen table that meet the search criteria are identified and the first row is shown in a table form.

                When clicking on the 'Insert New Row' button, an empty table form is shown and one may type a new row for the selected table.

                Table form

                For each table that has a primary key in the database there is a specific table form which shows the column names to the left and entry fields to the right.

                For each reference to another table, a choice field is generated which holds the values of all the rows of the referenced table.

                The entry fields for columns that belong to the primary key of the table are not editable. If you want to update a part of the primary key, you have to delete the row and insert a new row.

                ALTER TABLE <tablename>                 ADD COLUMN <columnname> Datatype [(columnSize[,precision])] [DEFAULT 'defaultValue' [NOT NULL]] [BEFORE <existingcolumn>];

                Adds the column to the end of the column list. Optional attributes, size and default value (with or without NOT NULL) can be specified. The optional BEFORE <existingcolumn> can be used to specify the name of an existing column so that the new column is inserted in a position just before the <existingcolumn>. If NOT NULL is specified and the table is not empty, then a default value must be specified.

                ALTER TABLE <tablename> DROP COLUMN <columnname>;

                Drops the column from the table. Will not work if column is part of a primary key, unique or foreign key constraint.

                ALTER TABLE <tablename> ADD CONSTRAINT <constraintname> UNIQUE (<column list>);

                Adds a unique constraint to the table. This will not work if there is already a unique constraints covering exactly the same <column list>.

                ALTER TABLE <tablename> ADD CONSTRAINT <constraintname> FOREIGN KEY (<column list>) REFERENCES <exptablename> (<column list>) [ON DELETE CASCADE];

                Adds a foreign key constraint to the table, using the same constraint syntax as when the foreign key is specified in a table definition.

                ALTER TABLE <tablename> DROP CONSTRAINT <constraintname>;

                Drops a named unique or foreign key constraint from the table.

                ALTER TABLE <tablename> RENAME TO <newname>;

                ALTER INDEX <indexname> RENAME TO <newname>;

                Names can be changed so long as they do not conflict with other user-defined or sytem-defined names.


                CALL Expression ;

                Any expression can be called like a stored procedure, including, but not only Java stored procedures or functions. This command returns a ResultSet with one column and one row (the result) just like a SELECT statement with one row and one column.

                See also: Stored Procedures / Functions, Expression.



                CHECKPOINT ;

                Closes the database files, shrinks the script file and opens the database.

                See also: SHUTDOWN, SET LOGSIZE.



                COMMIT [WORK] ;

                Ends a transaction and makes the changes permanent.

                See also: ROLLBACK, SET AUTOCOMMIT.



                CONNECT USER username PASSWORD password ;

                Connects to the database as a different user. Use "" for an empty password.

                See also: GRANT, REVOKE



                CREATE ALIAS function FOR javaFunction ;

                Creates an alias for a Java function. The function must be accessible from the JVM in that the database runs. Example:
                CREATE ALIAS ABS FOR "java.lang.Math.abs"

                See also: CALL, Stored Procedures / Functions



                CREATE [UNIQUE] INDEX index ON table (column [, ...]) ;

                Creates an index on one or more columns in a table.
                Creating an index on searched columns may improve performance.

                See also: CREATE TABLE, DROP INDEX



                CREATE [ MEMORY | CACHED | TEMP | TEXT ] TABLE name
                ( columnDefinition [, ...] [, constraintDefinition...]) ;

                Creates a tables in the memory (default) or on disk and only cached in memory. Identity columns are autoincrement columns. They must be integer columns and are automatically primary key columns. The last inserted value into an identity column for a connection is available using the function IDENTITY(), for example (where Id is the identity column):
                INSERT INTO Test (Id, Name) VALUES (NULL,'Test'); CALL IDENTITY();

                columnDefinition:
                columnname Datatype [(columnSize[,precision])] [DEFAULT 'defaultValue'] [[NOT] NULL] [IDENTITY] [PRIMARY KEY]

                the default value must be enclosed in singlequotes

                constraintDefinition:
                [ CONSTRAINT name ]
                UNIQUE ( column [,column...] ) |
                PRIMARY KEY ( column [,column...] ) |
                FOREIGN KEY ( column [,column...] ) REFERENCES refTable ( column [,column...]) [ON DELETE CASCADE]

                CREATE TRIGGER name {BEFORE|AFTER} {INSERT|UPDATE|DELETE} ON table [FOR EACH ROW] [QUEUE n] [NOWAIT] CALL triggerClass ;

                triggerClass is an application-supplied class that implements the org.hsqldb.Trigger interface e.g. "myPackage.trigClass". It is the fire method of this class that is invoked when the trigger event occurs. Ensure that triggerClass is present in the classpath which you use to start hsqldb.

                When the 'fire' method is called, it is passed the following arguments:
                fire (String name, String table, Object row[])
                where 'row' represents the row acted on, with each column being a member of the array. The mapping of row classes to database types is specified in Datatypes

                If the trigger method wants to access the database, it must establish its own JDBC connection. Note that this means any access is in a separate transaction. The jdbc:default:connection: URL is not currently supported.

                Implementation note: In the interests of not blocking the database's main thread, each trigger runs in a thread that will wait for its firing event to occur; when this happens, the trigger's thread calls triggerClass.fire. There is a queue of events waiting to be run by each trigger thread. This is particularly useful for 'FOR EACH ROW' triggers, when a large number of trigger events occur in rapid succession, without the trigger thread getting a chance to run. If the queue becomes full, subsequent additions to it cause the database engine to suspend awaiting space in the queue. Take great care to avoid this situation if the trigger action involves accessing the database, as deadlock will occur. This can be avoided either by ensuring the QUEUE parameter makes a large enough queue, or by using the NOWAIT parameter, which causes a new trigger event to overwrite the most recent event in the queue. The default queue size is 1024. Note also that the timing of trigger method calls is not guaranteed, so applications should implement their own synchronization measures if necessary.

                See also: DROP TRIGGER



                CREATE USER username PASSWORD password [ADMIN] ;

                Creates a new user or new administrator in this database. Empty password can be made using "".
                Only an administrator do this.

                CREATE VIEW viewname AS SELECT ... FROM ... [ WHERE Expression ] ;

                A view can be thought of as either a virtual table or a stored query. The data accessible through a view is not stored in the database as a distinct object. What is stored in the database is a SELECT statement. The result set of the SELECT statement forms the virtual table returned by the view. A user can use this virtual table by referencing the view name in SQL statements the same way a table is referenced. A view is used to do any or all of these functions:

                Restrict a user to specific rows in a table. For example, allow an employee to see only the rows recording his or her work in a labor-tracking table.

                Restrict a user to specific columns. For example, allow employees who do not work in payroll to see the name, office, work phone, and department columns in an employee table, but do not allow them to see any columns with salary information or personal information.

                Join columns from multiple tables so that they look like a single table.

                Aggregate information instead of supplying details. For example, present the sum of a column, or the maximum or minimum value from a column.

                Views are created by defining the SELECT statement that retrieves the data to be presented by the view. The data tables referenced by the SELECT statement are known as the base tables for the view. In this example, is a view that selects data from three base tables to present a virtual table of commonly needed data: 

                    CREATE VIEW mealsjv AS
      SELECT m.mid mid, m.name name, t.mealtype mt, a.aid aid,
             a.gname + ' ' + a.sname author, m.description description,
             m.asof asof
        FROM meals m, mealtypes t, authors a
       WHERE m.mealtype = t.mealtype
	     AND m.aid = a.aid;
                You can then reference mealsjv in statements in the same way you would reference a table: 

                    SELECT *
      FROM mealsjv
                A view can reference another view. For example, mealsjv presents information that is useful for long discriptions that contain identifers, but a short list might be all a web page display needs. A view can be built that selects only specific mealsjv columns: 

                    CREATE VIEW mealswebv AS
      SELECT name, author
        FROM mealsjv

                DELETE FROM table [ WHERE Expression ] ;

                Removes rows in a table.

                See also: Expression, INSERT, SELECT



                DISCONNECT ;

                Closes this connection. It is not required to call this command when using the JDBC interface: it is called automatically when the connection is closed. After disconnecting, it is not possible to execute other queries (also not CONNECT) with this connection.

                See also: CONNECT



                DROP INDEX index ;

                Removes the specified index from the database. Will not work if the index backs a UNIQUE of FOREIGN KEY constraint.

                See also: CREATE INDEX



                DROP TABLE table [IF EXISTS] ;

                Removes a table, the data and indexes from the database. When IF EXIST is used, the statement returns true if the table does not exist.

                See also: CREATE TABLE


                DROP TRIGGER trigger                 ;

                Removes a trigger from the database.

                See also: CREATE TRIGGER



                DROP USER username ;

                Removes a user from the database.
                Only an administrator do this.

                See also: CREATE USER



                DROP VIEW viewname [IF EXISTS] ;

                Removes a view from the database. When IF EXIST is used, the statement returns true if the view does not exist.

                See also: CREATE VIEW



                GRANT { SELECT | DELETE | INSERT | UPDATE | ALL } [,...]
                ON { table | CLASS "package.class" } TO { username | PUBLIC } ;

                Assigns privileges to a user or to all users (PUBLIC) for a table or for a class. To allow a user to call a function from a class, the right ALL must be used. Examples:
                GRANT SELECT ON Test TO GUEST
                GRANT ALL ON CLASS "java.lang.String" TO PUBLIC
                Only an administrator do this.

                See also: REVOKE, CREATE USER



                INSERT INTO table [ ( column [,...] ) ]
                { VALUES(Expression [,...]) | SelectStatement } ;

                Adds one or more new rows of data into a table.



                REVOKE { SELECT | DELETE | INSERT | UPDATE | ALL } [,...]
                ON { table | CLASS "package.class" } TO { username | PUBLIC } ;

                Withdraws privileges from a user or for PUBLIC (all users) for a table or class.
                Only an administrator may do this.

                See also: GRANT



                ROLLBACK [WORK] ;

                Undoes changes made since the last COMMIT or ROLLBACK.

                See also: COMMIT



                SCRIPT ['file'] ;

                Creates an SQL script describing the database. This file is saved on the machine where the database files are located.
                Only an administrator may do this.



                SELECT [{LIMIT n m | TOP m}][DISTINCT]
                { selectExpression | table.* | * } [, ... ]
                [ INTO [CACHED | TEMP | TEXT] newTable ]
                FROM tableList
                [ WHERE Expression ]
                [ GROUP BY Expression [, ...] ]
                [ ORDER BY orderExpression [, ...] ]
                [ { UNION [ALL] | {MINUS|EXCEPT} | INTERSECT } selectStatement ] ;

                Retrieves information from one or more tables in the database.

                tableList:
                table [ { INNER | LEFT OUTER } JOIN table ON Expression ] [, ...]

                selectExpression:
                { Expression | COUNT(*) | {COUNT | MIN | MAX | SUM | AVG} ([DISTINCT] Expression) }

                orderExpression:
                { columnNr | columnAlias | selectExpression } [ ASC | DESC ]

                LIMIT n m: creates the result set for the SELECT statement first and then discards the first n rows and returns the first m rows of the remaining result set. Special cases: LIMIT 0 m is equivalent to TOP m or FIRST m in other RDBMS's; LIMIT n 0 discards the first n rows and returns the rest of the result set.

                TOP m is equivalent to LIMIT 0 m

                See also: INSERT, UPDATE, DELETE



                SET AUTOCOMMIT { TRUE | FALSE } ;

                Switches on or off the connection's auto-commit mode. If switched on, then all statements will be committed as individual transactions. Otherwise, the statements are grouped into transactions that are terminated by either COMMIT or ROLLBACK. By default, new connections are in auto-commit mode.



                SET IGNORECASE { TRUE | FALSE } ;

                Disables (ignorecase = true) or enables (ignorecase = false) the case sensitivity of text comparison and indexing. By default, new databases are case sensitive. The sensitivity must be switched before creating tables. Existing tables and their data are not affected. When switched on, the data type VARCHAR is set to VARCHAR_IGNORECASE. This special data type can also be used without switching global ignorecase on. So it is possible to have some columns case sensitive and some not, even in the same table.
                Only an administrator may do this.



                SET LOGSIZE size ;

                Sets the maximum size in MB of the .script file. Default is 200 MB. The database will be closed and opened (just like using CHECKPOINT) if the .script file gets over this limit, and so the .script file will shrink. 0 means no limit.

                See also: CHECKPOINT



                SET PASSWORD password ;

                Changes the password of the currently connected user. Empty password can be set using ""



                SET REFERENTIAL_INTEGRITY { TRUE | FALSE } ;

                This commands enables / disables the referential integrity checking (foreign keys). Normally it should be switched on (this is the default) but when importing data (and the data is imported in the 'wrong' order) the checking can be switched off.
                Only an administrator may do this.

                See also: CREATE TABLE


                SET TABLE tableName INDEX 'index1rootPos index2rootPos ... '.

                This command is only used internally to store the position of index roots in the .data file. It appears only in database script files; it should not be used directly.


                SET TABLE <tablename> READONLY {TRUE | FALSE} ;

                Sets the table as read only



                SET TABLE <tablename> SOURCE <file and options> [DESC] ;

                For details see the document TextTables.html.

                This command is used exclusively with TEXT tables to specify which file is used for storage of the data. The optional DESC qualifier results in the text file indexed from the end and opened as readonly. The <file and options> argument is a double quoted string that consists of:

                <file and options>::= <doublequote> <filepath> [<semicolon> <option>...] <doublequote>

                Example: SET TABLE mytable SOURCE "myfile;fs=|;vs=.;lvs=~"

                HSQLDB also recognises the following special indicators for separators:

                    \semi - semicolon
                    \quote - quote
                    \space - space character
                    \apos - apostrophe
                    \n - newline - Used as an end anchor (like $ in regular expressions)
                    \r - carriage return
                    \t - tab
                    \\ - backslash
                    \u#### - a Unicode character specified in hexadecimal

                Only an administrator may do this.


                SET WRITE_DELAY { TRUE | FALSE } ;

                When the write delay is switched on, the executed commands are written to the log file (.script) at most 1 second after they are executed. This improves the performance of applications that makes a lot of inserts/updates/deletes. When switched off (this is the default) then all SQL commands are written into the log file (.script) just after they are executed.
                Only an administrator may do this.



                SHUTDOWN [ IMMEDIATELY | COMPACT ] ;

                Closes the current database.

                SHUTDOWN performs a checkpoint to creates a new .script file that has the minimum size and contains the data for memory tables only. It then backs up the .data file containing the CACHED TABLE data in zipped format to the .backup file and closes the database.

                SHUTDOWN IMMEDIATELY just closes the database files (like an external poweroff); this command is used internally to test the recovery mechanism. This command should not be used as the routine method of closing the database.

                SHUTDOWN COMPACT writes out a new .script file which contains the data for all the tables, including CACHED and TEXT tables. It then deletes the existing text table files and the .data file before rewriting them. After this, it backs up the .data file in the same way as normal SHUTDOWN. This operations shrinks all files to the minimum size.
                Only an administrator may do this.



                UPDATE table SET column = Expression [, ...] ;
                [WHERE Expression]

                Modifies data of a table in the database.

                Datatypes: The types on the same line are equivalent.

                INTEGER | INT "int" | "java.lang.Integer"
                DOUBLE [PRECISION] | FLOAT "double" | "java.lang.Double"
                VARCHAR "java.lang.String"
                VARCHAR_IGNORECASE "java.lang.String"
                CHAR | CHARACTER "java.lang.String"
                LONGVARCHAR "java.lang.String"
                DATE "java.sql.Date"
                TIME "java.sql.Time"
                TIMESTAMP | DATETIME "java.sql.Timestamp"
                DECIMAL "java.math.BigDecimal"
                NUMERIC "java.math.BigDecimal"
                BIT "boolean" | "java.lang.Boolean"
                TINYINT "byte" | "java.lang.Byte"
                SMALLINT "short" | "java.lang.Short"
                BIGINT "long" | "java.lang.Long"
                REAL "double" | "java.lang.Double"
                BINARY "byte[]"
                VARBINARY "byte[]"
                LONGVARBINARY "byte[]"
                OTHER | OBJECT "java.lang.Object"

                The uppercase names are the data types names defined by the SQL standard or commonly used by RDMS's. The data types in quotes are the Java class names - if these type names are used then they must be enclosed in quotes because in Java names are case-sensitive.

                The recommended Java mapping for the JDBC datatype FLOAT is as a Java type "double". Because of the potential confusion it is recommended that DOUBLE is used instead of FLOAT.

                VARCHAR_IGNORECASE is a special case-insensitive type of VARCHAR. This type is not portable.

                In HSQLDB, when defining CHAR and VARCHAR columns, the SIZE argument is optional and defaults to 0. If any other size is specified, it is stored in the database definition but is not enforeced by default. Once you have created the database (before adding data), you can close the database and add a database property value:

                sql.enforce_size=true

                This will enforce the specified size and pad CHAR fields with spaces to fill the size.

                CHAR and VARCHAR and LONGVARCHAR columns are by default compared and sorted according to POSIX standards. To use the current JRE locale for sorting and comparison, add the following database property to the properties file.

                sql.compare_in_locale=true

                Columns of the type OTHER or OBJECT contain the serialized form of a Java Object in binary format. To insert or update such columns, a binary format string (see below under Expression) should be used. Using PreparedStatements with JDBC automates this transformation.



                Comments


                -- SQL style line comment
                // Java style line comment
                /* C style line comment */

                All these types of comments are ignored by the database.



                Stored Procedures / Functions

                Stored procedures are Java functions that are called directly from the SQL language or using an alias. Calling Java functions (directly or using the alias) requires that the Java class can be reached by the database (server). The syntax is:

                "java.lang.Math.sqrt"(2.0)

                This means the packacke must be provided, and the name must be written as one word, and inside " because otherwise it is converted to uppercase (and not found).

                An alias can be created using the command CREATE ALIAS:

                CREATE ALIAS SQRT FOR "java.lang.Math.sqrt"

                When an alias is defined, then the function can be called additionally using this alias:

                SQRT(2.0)

                Expression:

                [NOT] condition [ { OR | AND } condition ]

                condition:
                { value [ || value ]
                | value { = | < | <= | > | >= | <> | != | IS [NOT] } value
                | EXISTS(selectStatement)
                | value BETWEEN value AND value
                | value [NOT] IN ( {value [, ...] | selectStatement } )
                | value [NOT] LIKE value [ESCAPE] value }

                value:
                [ + | - ] { term [ { + | - | * | / } term ]
                | ( condition )
                | function ( [parameter] [,...] )
                | selectStatement giving one value

                term:
                { 'string' | number | floatingpoint
                | [table.]column | TRUE | FALSE | NULL }

                string:
                Strings in HSQLDB are Unicode strings. A string starts and ends with a single ' (singlequote). In a string started with ' (singlequote) use '' (two singlequotes) to create a ' (singlequote).

                The LIKE keyword uses '%' to match any (including 0) number of characters, and '_' to match exactly one character. To search for '%' itself, '\%' must be used, for '_' use '\_'; or any other escaping character may be set using the ESCAPE clause.

                name:
                The character set for identifiers (names) in HSQLDB is Unicode.

                A unquoted identifier (name) starts with a letter and is followed by any number of letters or digits. In unquoted identifiers, lowercase characters are converted to uppercase. Because of this, unquoted names are not case sensitive when used in SQL statements.

                Quoted identifiers can be used as names (for tables, columns, constraints or indexes). Quoted identifiers start and end with " (one doublequote). A quoted identifier can contain any Unicode character, including space. In a quoted identifier use "" (two doublequotes) to create a " (one doublequote). With quoted identifiers it is possible to create mixed-case table and column names. Example: CREATE TABLE "Address" ("Nr" INTEGER,"Name" VARCHAR); SELECT "Nr", "Name" FROM "Address";

                The equivalent quoted identifier can be used for an unquoted identifer by converting the identifier to all uppercase and quoting it. For example, if a table name is defined as Address2 (unquoted), it can be referred to by its quoted form, "ADDRESS2", as well as address2, aDDress2 and ADDRESS2. Quoted identifiers should not be confused with SQL strings.

                Quoting can sometimes be used for identifiers when there is an ambiguity. For example:

                SELECT COUNT(*) "COUNT" FROM MYTABLE;

                Portability between different JRE locales is an issue when accented characters are used in unquoted identifiers. Because native Java methods are used to convert the identifier to uppercase, the result may vary among different locales. It is recommended that accented characters are used only in quoted identifiers.

                When using JDBC methods that take table, column, or index identifiers as arguments, treat the names as they are registered in the database. With these methods, unquoted identifiers should be used in all-uppercase to get the correct result. Quoted identifiers should be used in the exact case combination as they were defined - no quote character should be included in the name. JDBC methods that return a result set containing such identifiers return unquoted identifiers as all-uppercase and quoted identifiers in the exact case they are registered in the database (a change from 1.6.1 and previous versions).

                values:
                A 'date' value starts and ends with ' (singlequote), the format is yyyy-mm-dd (see java.sql.Date).
                A 'time' value starts and ends with '                 (singlequote), the format is hh:mm:ss (see java.sql.Time).
                A 'timestamp' or 'datetime' value starts and ends with '                 (singlequote), the format is yyyy-mm-dd hh:mm:ss.SSSSSSSSS (see java.sql.Timestamp).

                When specifying default values for date / time columns in CREATE TABLE statements, or in SELECT,INSERT, and UPDATE statements, special values 'now', 'today', 'current_timestamp', 'sysdate', 'current_time' and 'current_date' (case independent) can be used. 'now' is used for TIME and TIMESTAMP columns, 'today' is used for DATE columns. Example: 

                 CREATE TABLE T(D DATE DEFAULT 'today');
 CREATE TABLE T1(TS TIMESTAMP DEFAULT 'now');

                Binary data starts and ends with ' (singlequote), the format is hexadecimal. '0004ff' for example is 3 bytes, first 0, second 4 and last 255 (0xff).

                Any number of commands may be combined. With combined commands, ';' (semicolon) must be used at the end of each command to ensure data integrity, despite the fact that the program may not return an error when it is not used.

If you have time and the Java skills to port it now-- please contact me ASAP: blaine.simpson@admc.com (BTW, it will take considerable effort to just port the existing behavior from Bash to Perl, but the real difficultiy would be to improve the run-time by not invoking a new JVM for each test run. Specifically, Java uses a very closed design for providing stdin, stdout, stderr, and one can't open and close these pipes at will, as we do in the Bash script). HOW TO RUN Typical usage (executes all tests): cd .../testrun/sqltool ./runtests.bash Run tests on any SQL files: .../testrun/sqltool/runtests.bash file1.sql file2.sql... If there are any test failures, the failed SQL scripts will be listed at the end of the results. To get details about the failure, run runtests.bash with just one of the failed SQL scripts at a time, and with the Verbose option, like ./runtests.bash -v failedscript.sql To see all available invocation methods: ./runtests.bash -h FILE NAMING AND ASCII/BINARY CONVENTIONS You can name SQL scripts anything that you want, except that the filename suffixes ".nsql" and ".inter" are reserved for negative and interactive SQL scripts, correspondingly (see the next section about that). If you plan to run runtests.bash with no filename arguments, it will execute all *.sql, *.nsql, an d*.inter scripts in the current directory. So, if you plan to run runtests.bash this way, you must take care to name only scripts **which you want executed at the top level** with extensions sql, nsql, inter. By "at the top level", I mean that if you are nesting SQL scripts with the \i command, you can't name the nested script with suffix .sql, .nsql, or .inter or the script will accidentally be executed directly when you run runtests.bash without script arguments. It's a simple concept, but, as you can see, it's a little difficult to explain, so here's an example. You have a script name "top.sql" which contains \i nested.sql You can run "./runtests.bash top.sql" and everything will work fine-- runtests.bash will execute "top.sql" which will nest "nested.sql". But if you run just "./runtests.bash", runtests.bash will run "top.bash", which will nest "nested.bash" just like before, but runtests.bash will also execute "nested.bash" directly, since it executes all files with extensions sql and nsql (and inter). Just use any filename suffix other than .sql, .nsql, and .inter for your nested SQL scripts and everything will work fine. If you are a HSQLDB developer and will be committing test scripts, then please use the following filename and type conventions: purpose suffix filetype -------------------- ------ ---------------------------- top-level SQL script .sql ASCII (mime-type text/plain) top-level neg. SQL .nsql ASCII (mime-type text/plain) interactive SQL script .inter ASCII (mime-type text/plain) nested \i SQL script .isql ASCII (mime-type text/plain) delimiter-sep-values .dsv Binary (no mime-type) If you will be adding new files to HSQLDB, please configure these extensions in for CVS or Subversion client accordingly. FINE POINT JUSTIFYING Binary TYPE FOR DSV FILES (Only read if you give a damned). The reason we're storing DSV files as binaries is because if CVS or Subversion saved them as ASCII, the line delimiters would be determined by the platform performing the check-out, and imports would fail if the computer executing nested.bash happened to be of different EOL type from the computer that checked out. (This would be the case any time that somebody built a distributable of any type which includes the .dsv files). NEGATIVE TESTS runtests.bash determines if a test script succeeds by checking if the exit status of SqlTool is zero. But we also need to test that scripts fail out when they should. I.e., we need to verify that if \c (continue-on-error) is false, and there is a syntax error, or a runtime SQL failure, that SqlTool exits with non-zero exit status, as it should. For this, I have invented the convention that SQL scripts named with suffix ".nsql" are just like normal SQL files, except that they are expected to fail. Here's an example to confirm that you understand. ./runtests.bash 1.sql 2.sql 3.nsql 4.nsql 5.sql This test run will report test failures for 1.sql, 2.sql, and 5.sql only if SqlTool fails when executing them. It will report test failures for 3.nsql and 4.nsql only if SqlTool succeeds when executing them. I.e., runtests.bash _expects_ SqlTool to fail when executing *.nsql files. Negative test scripts should be small and should fail out as early as possible. The reason for this is that if there is an accidental error before the point of your test, the script will fail out early providing a false negative SqlTool exit code, thereby silently missing your test completely. INTERACTIVE TESTS Interactive test are invoked like java... SqlTool... mem < scriptname.inter in order to test interactive ":" commands. The : commands are disabled if an SQL script path(s) is given directly as an SqlTool parameter. I.e., SqlTool runs non-interactively if an SQL script path is given as a pareter; therefore, to test interactive commands, we invoke SqlTool without a script name, and instead pipe the script into SqlTool as stdin. (Using script name of "-" would do the reverse, it would run in interactive mode even though getting input from stdin). Remember to put "\c false" at the top of your interacive scripts, or errors will be ignored. Account for this command when counting command numbers in the command history. hsqldb-1.8.0.10.orig/testrun/sqltool/args-noinput.sql0000644000175000017500000000061410064205664021173 0ustar renerene/* $Id: args-noinput.sql,v 1.1 2004/06/17 03:10:43 unsaved Exp $ See readme.txt in this directory for how to unit test SqlTool.

This is an annotated example. Don't use this as a template. See the readme.txt file about that. This is an annotated example on how to test SqlTool run in raw mode. By raw mode, I mean running SqlTool with a hyphen as the only SQL file argument, like java org.hsqldb.util.SqlTool mem - This causes SqlTool to read stdin, but non-interactively (e.g. command-line editing won't work and there is no login banner, etc.). This SQL test file runs SqlTool in raw mode by virtue of using "inputAsFile" false (the default) and specifying filename of "-" with "arg". N.b. that there are no annotations between the "HARNESS_METADATA BEGIN" line and the "HARNESS_METADATA END" lines below. This is because only harness metadata name/value pairs are permitted between those lines. In general, you are best off using urlid of "mem", which we assume that the user has configured as a memory-only database (as documented in the readme.txt file). You specify the urlid to be used by this file by using the 'arg' setting as described below. Harness metadata settings: arg: An argument for SqlTool. Unless you are testing bad command-line args, you must give at least a urlid as an arg. The only SqlTool arg that you do not give is, if you set inputAsFile to true (see below), you do not use 'arg' to specify this file name. jvmarg: An argument to come between "java" and "org.hsqldb.util.SqlTool" requireStdoutRegex: Regular expression to require from stdout of SqlTool rejectStdoutRegex: Regular expression to reject from stdout of SqlTool requireErroutRegex: Regular expression to require from errout of SqlTool rejectErroutRegex: Regular expression to reject from errout of SqlTool exitValue: Required exit value from the SqlTool run. Default is 0. Specify no value at all (i.e. a line containing just "exitValue") to ignore the exit value. inputAsFile: "true" or "false" (defaults to "false"). If "false", this file you are reading will be passed to SqlTool via stdin. If "true", the filename of the file you are reading will be given to SqlTool as the last command-line argument (do NOT give it with 'arg' or SqlTool will get that argument twice!). All settings are optional. For all but the last 2, you can give as many as you want. You could, for example give 3 args, 2 jvmargs, 20 requireStdoutRegexes. The reason for the exception where a filename 'arg' is automatically added if inputAsFile is true, is so you don't have to maintain hard-coded file names in SQL files, and you don't need to be concerned about operating system case sensitivity or case-munging problems. You can add args for other filenames, to test "SqlTool... file1 file2...", just be aware that this current file will be appended in last position if inputAsFile is true.

This SQL test file runs SqlTool in interactive mode by virtue of using "inputAsFile" false (the default) and not specifying any SQL filename (or "-") with "arg".

Unless you are testing bad command-line args, you must give at least a urlid as an arg.

Hsqldb documentation from DocBook source ----------------------------------------------------- $Id: readmedocbook.txt,v 1.7 2005/07/25 21:05:46 unsaved Exp $ 1. OBTAIN REQUIRED LIBRARIES AND STYLE SHEETS If you are using a version of Java earlier than 1.4, then you will have to get XML and XSLT libraries supported by DocBook. (Java 1.4 users skip to the next paragraph). I suggest the Xerces XML library and Xalan XSLT libraries, both of which are available in the Xalan Java 2 distribution file xalan-j-*-bin.* (not xalan-j--bin-2jars.*), available at http://www.apache.org/dyn/closer.cgi/xml/xalan-j You will need to put the jars xalan.jar, xml-apis.jar, and xercesImpl.jar into your classpath. If you are using the Sun JDK 1.4, and get an exception when building the docbooks, you may need newer Xerces / Xalan libraries. See also http://xml.apache.org/xalan-j/faq.html If you are building on one of the Sourceforge shell servers, then you can skip this step because I have all of the needed resources under /home/users/us/unsaved. You shouldn't build docs on Sourceforge unless you are a developer who is building the documentation for publishing. You need the following resources. In all cases, use the latest stable version unless there is some specific reason to use something else. ant-contrib*.jar from ant-contrib-*-bin.*, available from http://sourceforge.net/project/showfiles.php?group_id=36177 Place this jar into the lib subdirectory of your Ant installation. [Some distros spread the Ant files all over the place, and the lib directory isn't referenced at all. In that case, just add the jar file to your classpath (exporting if needed by your shell) before running ant. The docbook-xsl package from http://sourceforge.net/project/showfiles.php?group_id=21935&package_id=16608 (or, for Linux RPM users, the docbook-xsl-stylesheets package). You need at least version 1.61. Extract anyplace. That's all if you just want to build HTML docs. If you want to build PDF or postscript, then you also need the following. Binary distro of FOP, available from http://www.apache.org/dyn/closer.cgi/xml/fop Extract it anyplace. JimiProClasses.zip from Sun's JIMI SDK, available at http://java.sun.com/products/jimi Just pull the JimiProClasses.zip file out and rename it to jimi-1.0.jar in the lib subdirectory of your FOP installation. (If this seems weird to you, read about it in the FOP docs. Note that we use JIMI instead of JAI because JAI is non-portable). 2. MAKE A build.properties TO TELL Ant WHERE TO FIND THE LIBRARIES AND STYLE SHEETS Create a Java properties file named "build.properties" in the same directory as this readme file. (If there's already one there, then just add to it). Add values for 'docbook.xsl.home' and for 'fop.home'. This example build.properties file (which works on cvs.sourceforge.net) shows what is needed. docbook.xsl.home: /home/users/u/un/unsaved/docbook-xsl-1.65.1 fop.home: /home/users/u/un/unsaved/fop-0.20.5 (RPM users be aware that docbook-xsl-stylesheets installs the style sheets under /usr/share/sgml/docbook/docbook-xsl-stylesheets. Run "rpm -ql docbook-xsl-stylesheets"). THE REMAINDER OF THIS DOCUMENT IS ONLY FOR PEOPLE MESSING WITH THE BUILD FILE ITSELF. There's no need to understand this stuff if you are only using external targets. RELATIONSHIPS AMONG THE HSQLDB DOCBOOK-RELATED ANT TARGETS: * denotes inheritall invocations. docbook docbooks-html -> html docbooks-chunk -> *-ddIterate ->*-condlGenBook -> chunk docbooks-pdf -> pdf [docbooks-ps ->] ps pdf/ps fo *-fop -> -initfop chunk/html/fo -setXslFilesets -preDocbook *-htmlXslt/*-foXslt -postDocbook -preDocbook -> *-sandwich -postDocbook (There's a good chance that this relationship "diagram" will get out-of-date. Best to use this as a guide and verify any assumptions against the real build.xml file). hsqldb-1.8.0.10.orig/build/switchToJDK14.bat0000644000175000017500000000223710036536603016716 0ustar renerenecd

00:19:47 unsaved Exp $ Remove the old package pkgrm HSQLDBhsqldb Your "data" and your configuration settings will not be removed. If you use default locations, here are the remnants which you need to be concerned about: Your databases will still reside in directories like /usr/hsqldb-1.7.1/data/db1 (and similar for databases you may have created). One server.properties or webserver.properties file in each of the database instance directories (see previous item). You main configuration file will be backed up to a file like /etc/hsqldb.conf.20050724 (where the last element of the file name is a date stamp). READ THIS PARAGRAPH ONLY IF YOU ARE RUNNING MULTIPLE DB INSTANCES The version 1.7.1 init script ran a separate JVM for each database instance. You can still do this in the new version by using multiple copies of the init script and the main configuration file (/etc/hsqldb.conf). See the main readme.txt file about how to do that. The primary method to support multiple database instances in this version, however, is to run all of your instances in a single JVM. This is the most efficient way to run HSQLDB for most (but certainly not all) environments. The new init script uses server.properties files directly in /opt/hsqldb/data, not in the instance-specific directories like /opt/hsqldb/data/db1; and it depends on the server.properties files to specify the data sources (instead of the rather restive method of supporting only standalone type databases which rely on the directory name). Therefore, you need to merge your web/server.properties files from /usr/hsqldb-1.7.1/data/*/*server.properties to the directory /opt/hsqldb/data and specify the database instances as documented in the server.properties section of the Advanced chapter of the HSQLDB User Guide. Most users will just want a single server.properties file that will simply list all database instances. You can, however, run different listeners on different ports in order to serve all combinations of Server/WebServer/port-numbers/SSL/etc. To run multiple listeners like this (all in the single JVM), you set INVOC_ADDL_ARGS to specify the *Server classes to run, and the startup parameters which will override the web/server.properties settings for that one listener. I. Make sure your data is accessible. Your instance data for 1.7.1 resides under /usr/hsqldb-1.7.1/data/db1. You can either leave it there and change the value of SERVER_HOME in /etc/hsqldb.conf to /usr/hsqldb-1.7.1/data, or move everything from /usr/hsqldb-1.7.1/data/db1 to the new default location, /opt/hsqldb/data/db1. II. Make your web/server.properties file accessible. Move the new server.properties to server.properties or webserver.properties in your SERVER_HOME (see previous item). III.Update your web/server.properties file. Edit the web/server.properties file to (a) merge in changes which you have made to the old web/server.properties residing in your .../data/db1 directory (which will no longer be used); and (b) to make sure that the path to .../data/db1 is correct. If the filepath is relative, it is relative to SERVER_HOME. IV. Merge any customizations which you may have made from /etc/hsqldb.conf.20050724 into /etc/hsqldb.conf. You will see that the way several settings are made have changed, but the variable names and comments should make it clear how to make new settings which are equivalent to your old settings. As an example, version 1.7.1 had settings for HSQLDB_HOME and JAVA_HOME. The new version has the more specific settings HSQLDB_JAR_PATH and JAVA_EXECUTABLE instead. hsqldb-1.8.0.10.orig/build/packaging/pkg/readme.txt0000644000175000017500000001605210273521157020430 0ustar renereneREADME FOR THE SOLARIS HSQLDB PACKAGE $Id: readme.txt,v 1.14 2005/07/28 15:47:19 unsaved Exp $ JAVA SUPPORT The delivered hsqldb.conf uses /usr/bin/java (which on Solaris is equivalent to /bin/java since /bin is just a sym-link to /usr/bin). To use some other JRE, set JAVA_EXECUTABLE in /etc/hsqldb.conf. The hsqldb.jar file was built with Sun Java 1.5.0. It works with Sun JRE's 4.x and 5.x... You can certainly use this package with earlier versions of Java, but you will have to build a hsqldb.jar file for your Java version. All you need to do so is a HSQLDB distribution (this package will do, but you could also build it on another computer, even with a different operating system). a recent version of Ant, and a Java 1.3 JDK. It's pretty easy. Follow the instructions in the Building chapter of the HSQLDB User Guide at the bottom of the Building With Ant subsection. If you are going to run Java 1.x on Solaris (why!!!?), read the next paragraph. If you use this package with an IBM or open source JRE, please let me know how it works. If I get another job where I need to run a non-Sun JRE on Solaris, I'll make whatever changes are necessary. You can run multiple HSQLDB versions under different JRE's, or toggle back and forth, by renaming your hsqldb.jar's to indicate the JRE target version (like "hsqldb-jre23.jar" and "hsqldb-jre45.jar"), and changing the settings JAVA_EXECUTABLE and HSQLDB_JAR_PATH in /etc/hsqldb.conf as needed. Sun JRE 1.x USERS. (Do read the previous paragraph about rebuilding hsqldb.jar). Sym-links don't work right for at least some Java 1.x builds. Make sure that every element of your JAVA_EXECUTABLE path is a real directory (as opposed to a sym link). Known bug with Java 1.x: If you run the daemons as root (which is not the default), the default shutdown method fails and results in a long wait before shutdown with TERM signal succeeds. If this bothers you, then upgrade your java, don't run as root, or set a short timeout in the hsqldb config file. runUtil.sh and demo scripts: Don't use them. They are there for backwards compatibility only. Run "man java" to learn how to execute the HSQLDB classes. CONFIGURATION Main config file is /etc/hsqldb.conf on Solaris. You can have multiple versions of hsqldb installed, and you can have them installed to the same or different install bases (like /usr and /usr/local). Defaults to /opt. To keep these different baselines straight, the hsqldb homes have a version-number in their name. The last installation gets a sym-link called "hsqldb" (i.e., no version in it) right at the install base. So, to use the default (last) installation at any install base, just access "hsqldb". Example /opt/hsqldb-1.7.1 (default location on Solaris) /opt/hsqldb -> hsqldb-1.7.1 (sym-link to default hsqldb instance) By default, /etc/init.d/hsqldb will start up one HSQLDB Server which serves one database instance living at /opt/hsqldb/data/db1. It will run on the default Server port 9001 under user "hsqldb". You can customize this in lots of ways by editing /etc/hsqldb.conf and/or /opt/hsqldb/data/*server.properties files. You can, for example, serve standard hsql on multiple ports, plus http over multiple ports, some with SSL encrytion. Each port can serve its own list of database instances of various types (memory-only, file, jar, etc.). If multiple ports specify the same DB instance, then they will serve out a single, shared DB instance, just like you would want. All of this happening in a single JVM instance. See the comments in /etc/hsqldb.conf and the HSQLDB User Guide for information on how to do all this stuff. If you need JVM isolation for any reason, then you'll need to copy /etc/init.d/hsqldb to something else (perhaps /etc/init.d/hsqldb-alt) and edit this to use a different config file (perhaps /etc/hsqldb-alt.conf). Edit your new conf file as necessary and set up your hard links in /etc/rc?.d as required. (Linux users be aware that Solaris uses hard links for this, not sym links, and that you use links only for runlevels with state "changes"). In general, we recommend against it, but if you want to run your servers as root, just change OWNER to root in /etc/hsqldb.conf and skip the rest of this file. The rest of this file assumes that you are not running the daemons as user 'root'. By default, the daemons run as user 'hsqldb' (but you invoke the init scripts as root). You can not run a WebServer on the default port of 80 (since 80 is a privileged port). See the Advanced chapter of the HSQLDB User Guide. SOLARIS To install the Solaris package uncompress HSQLDBhsqldb-1_8_1-solaris.pkg.Z pkgadd -d HSQLDBhsqldb-1_8_1-solaris.pkg HSQLDBhsqldb (The version number will vary, of course). To install to an install base other than /opt, make an Admin file (like copy /var/sadm/install/admin/default) and set "basedir" whatever you want, then specify the Admin file to pkgadd with -a. pkgadd -a file.admin -d HSQLDBhsqldb-1_7_1-solaris.pkg HSQLDBhsqldb MULTIPLE INSTANCES You can install multiple instances of HSQLhsqldb, as long as the version is unique. If you want more than one copy of the same version, then you will have to copy files manually because Solaris doesn't permit that. If pkgadd refuses to let you install an additional package even though the version is unique, then you probably need to set the Admin file variable "instance" to "unique". If you don't understand what I say about Admin files, run "man pkgadd" and "man -s 4 admin". HSQLDB DEVELOPERS Most of the files in .../pkg/cfg are named like HSQLhsqldb.something. The intention was for the base name to be the entire package name, so they should be HSQLDBhsqldb.something. They will probably be renamed properly in some future version. To build a Solaris package, you need to do a cvs checkout of the hsqldb-dev module (HEAD or a static tag, depending on what you want). For suggestions of the checkout command, click the CVS tab at http://sourceforge.net/projects/hsqldb. Make sure to build documentation and hsqldb.jar before building this package! .../build/packaging/pkg/pkgbuild is the main script to build a Solaris package. Give the -p switch to rebuild the prototype file (definitely need to do that if there were any changes to anything in the software to be delivered... as opposed to just a version or package parameter change). Contents of the Solaris package. The package will contain exactly what is listed in the .../build/packaging/pkg/cfg/*.proto file which is generated by "pkgbuild -p". Several files in the checkedout out module are specifically not included in the Solaris package. To find out exactly what files are currently excluded, see the command beginning with "perl -ni.safe -we" in the pkgbuild script. At the time I am writing this, the perl command excludes the following: $HSQLDB_HOME/classes/... $HSQLDB_HOME/build/packaging $HSQLDB_HOME/.../CVS...

This jar contains both the database and the utilities and has been built with JDK 1.4.2. The supplied jar can be used with JRE version 1.4.x., and 1.5.x. It cannot be used with older version or JRE. JDK and JRE versions For use with JRE 1.1.x, 1.2.x or 1.3.x recompilation is necessary. For all the older versions, always use JDK 1.3.x to build the jar. The default build with JDK 1.3.x is not compatible to run under 1.1. If you require this compatibility, you should use the following ant command prior to the build (note the digit 1 in java1): ant switchtojava1target The jars compiled after this switch will run under JRE 1.3 too, but they use some deprecated JDK 1.1 methods. To switch back to non-deprecated code, use: ant switchoffjava1target Different jar sizes HSQLDB can be built in any combination of five different sizes. The smallest jar, hsqljdbc.jar, contains only the client side of the JDBC driver, without any server or client standalone programs. The next smallest jar, hsqldbmin.jar, contains only the database and JDBC support for in-process mode databases. The next smallest jar, hsqldbmain.jar, also contains support for server modes. The default size jar, hsqldb.jar, additionally contains the utilities such as Database Manager and Transfer Tool. The largest jar, hsqldbtest.jar, includes some test classes as well. You need the JUnit jar in the /lib directory in order to build and run the test classes. Run "ant explainjars" to see a summary of the contents of the different pre-defined jar targets. Javadoc can be built with Ant and batch files. The JDK used for the build has a marginal effect on the size. Newer JDK's support more JDBC methods and classes, resulting in slightly larger jars. JDK 1.1.x It is recommended not to use JDK 1.1.x for building the jar, as this version produces much larger jar sizes and the result is not upward compatible with newer JDK'S / JRE's. Use JDK 1.3.x to build the jar instead. You can then deploy the jar in JRE 1.1. Build methods: The preferred method of rebuilding the jar is with Ant. After installing Ant on your system use the following command from the /build directory: ant The command displays a list of different options for building different sizes of the HSQLDB Jar. The default jar is built using: ant jar The Ant method always builds a jar with the JDK that is used by Ant and specified in the JAVA_HOME environment variable. The script automatically converts the source files for compatibility with the given JDK. Before building the hsqldbtest.jar package, you should download the junit.jar and put it in the /lib directory, alongside servlet.jar, which is included in the .zip package. Batch Build A set of MSDOS batch files is also provided. These produce only the default jar size. The path and classpath variables for the JDK should of course be set before running any of the batch files. If you are compiling for JDK's other than 1.4.x, you should use the appropriate switchtoJDK11.bat or switchtoJDK12.bat to adapt the source files to the target JDK before running the appropriate buildJDK11.bat or buildJDK12.bat. As explained before, it is not recommended to use this method for building jars for use on JRE 1.1.x targets. fredt@users hsqldb-1.8.0.10.orig/build/switchToJDK12.bat0000644000175000017500000000223510036536603016712 0ustar renerenecd ..\ md classes del /s classes\*.class cd build cd ..\src\org\hsqldb\util javac -d ..\..\..\..\classes CodeSwitcher.java cd ..\..\..\..\build java -classpath "%classpath%;../classes" org.hsqldb.util.CodeSwitcher ../src/org/hsqldb/jdbc/jdbcStubs.java +JAVA2 -JDBC3 java -classpath "%classpath%;../classes" org.hsqldb.util.CodeSwitcher ../src/org/hsqldb/jdbc/jdbcCallableStatement.java +JAVA2 -JDBC3 java -classpath "%classpath%;../classes" org.hsqldb.util.CodeSwitcher ../src/org/hsqldb/jdbc/jdbcConnection.java +JAVA2 -JDBC3 java -classpath "%classpath%;../classes" org.hsqldb.util.CodeSwitcher ../src/org/hsqldb/jdbc/jdbcDatabaseMetaData.java +JAVA2 -JDBC3 java -classpath "%classpath%;../classes" org.hsqldb.util.CodeSwitcher ../src/org/hsqldb/jdbc/jdbcPreparedStatement.java +JAVA2 -JDBC3 java -classpath "%classpath%;../classes" org.hsqldb.util.CodeSwitcher ../src/org/hsqldb/jdbc/jdbcResultSet.java +JAVA2 -JDBC3 java -classpath "%classpath%;../classes" org.hsqldb.util.CodeSwitcher ../src/org/hsqldb/jdbc/jdbcStatement.java +JAVA2 -JDBC3 java -classpath "%classpath%;../classes" org.hsqldb.util.CodeSwitcher ../src/org/hsqldb/HsqlDateTime.java +JAVA2 -JDBC3 hsqldb-1.8.0.10.orig/build/buildDoc.bat0000644000175000017500000000033410036536603016135 0ustar renerenejavadoc -classpath ..\lib\servlet.jar;..\lib\junit.jar -sourcepath ..\src -d ..\doc\src -noindex -package org.hsqldb org.hsqldb.util org.hsqldb.lib org.hsqldb.store org.hsqldb.scriptio org.hsqldb.rowio org.hsqldb.jdbc hsqldb-1.8.0.10.orig/build/buildJDK14.bat0000644000175000017500000000115310245621257016207 0ustar renerene@echo HSQLDB build file for jdk 1.4 @echo *** we recommend the use of the ANT build.xml instead of this method @echo for all jdk's include the path to jdk1.x.x\bin in your system path statement cd ..\ md classes del /s classes\*.class cd src javac -O -nowarn -d ../classes -classpath "%classpath%;../classes;../lib/servlet.jar;." ./*.java org/hsqldb/*.java org/hsqldb/lib/*.java org/hsqldb/util/*.java cd ..\classes copy ..\src\org\hsqldb\util\*.gif org\hsqldb\util jar -cf ../lib/hsqldb.jar *.class org/hsqldb/*.class org/hsqldb/lib/*.class org/hsqldb/util/*.class org/hsqldb/util/*.gif cd ..\build pause hsqldb-1.8.0.10.orig/build/buildJDK12.bat0000644000175000017500000000344410245621455016212 0ustar renerene@echo HSQLDB build file for jdk 1.2.x and 1.3.x @echo *** we recommend the use of the ANT build.xml instead of this method @echo for all jdk's include the path to jdk1.x.x\bin in your system path statement cd ..\ md classes del /s classes\*.class cd src mkdir ..\temp copy org\hsqldb\jdbc\jdbcDataSource*.java ..\temp\ copy org\hsqldb\jdbc\jdbcSavepoint.java ..\temp\ copy org\hsqldb\jdbc\jdbcParameterMetaData.java ..\temp\ copy org\hsqldb\persist\NIOLockFile.java ..\temp\ copy org\hsqldb\persist\NIOScaledRAFile.java ..\temp\ del org\hsqldb\jdbc\jdbcDataSource*.java del org\hsqldb\jdbc\jdbcSavepoint.java del org\hsqldb\jdbc\jdbcParameterMetaData.java del org\hsqldb\persist\NIOLockFile.java del org\hsqldb\persist\NIOScaledRAFile.java javac -O -nowarn -d ../classes -classpath "%classpath%;../classes;../lib/servlet.jar;." ./*.java org/hsqldb/*.java org/hsqldb/jdbc/*.java org/hsqldb/persist/*.java org/hsqldb/rowio/*.java org/hsqldb/scriptio/*.java org/hsqldb/store/*.java org/hsqldb/lib/*.java org/hsqldb/util/*.java copy ..\temp\jdbcDataSource*.java org\hsqldb\jdbc copy ..\temp\jdbcSavepoint.java org\hsqldb\jdbc copy ..\temp\jdbcParameterMetaData.java org\hsqldb\jdbc copy ..\temp\NIOLockFile.java org\hsqldb\persist copy ..\temp\NIOScaledRAFile.java org\hsqldb\persist del ..\temp\jdbcDataSource*.java del ..\temp\jdbcSavepoint.java del ..\temp\jdbcParameterMetaData.java del ..\temp\NIOLockFile.java del ..\temp\NIOScaledRAFile.java rmdir ..\temp cd ..\classes copy ..\src\org\hsqldb\util\*.gif org\hsqldb\util jar -cf ../lib/hsqldb.jar *.class org/hsqldb/*.class org/hsqldb/jdbc/*.class org/hsqldb/persist/*.class org/hsqldb/rowio/*.class org/hsqldb/scriptio/*.class org/hsqldb/store/*.class org/hsqldb/lib/*.class org/hsqldb/util/*.class org/hsqldb/util/*.gif cd ..\build pause hsqldb-1.8.0.10.orig/data/0000755000175000017500000000000010416767250013540 5ustar renerenehsqldb-1.8.0.10.orig/bin/0000755000175000017500000000000010665471633013402 5ustar renerenehsqldb-1.8.0.10.orig/bin/hsqldb0000755000175000017500000004154310665471636014617 0ustar renerene#!/bin/sh # For boot-up and system shutdown, most UNIXes explicitly run a shell # interpreter.

Our DocBook strategy is still subject to change. For now... TO CREATE A NEW DOCBOOK BOOK Think up a base filename for your document. It should be nice and short, without funny characters (but hyphens, other than leading hypends, are ok). Example: sqltool. Hereafter, I'll refer to this as your "book name". Create a subdirectory of "docsrc" with name of your book name. I'll refer to this directory (docsrc + book name) as "your book directory". Inside your book directory, create your main DocBook source file with name of your book name + ".xml", e.g. "sqltool.xml". Your DocBook document may reference or include shared files in the main 'docsrc' directory as well as any files which you put into your book directory. You may want to include sample .java files, screen shots, or component DocBook source files. Usually you will just copy these files right into your book directory. For examples of just about everything, see .../docsrc/sqltool/sqltool.xml. Notice that sqltool.xml pulls in a document section from the main docsrc directory. Add your book name to the .cvsignore file in the doc directory. Until all of the CVS artifacts are moved out of the "doc" directory, you will need to edit the clean-doc target in the build.xml file in the build directory so that it will remove the derived files for your book from under the doc directory. HOW TO REFERENCE OR INCLUDE OTHER FILES IN YOUR DOCBOOK SOURCE FILE(s). To link to outside documents (which you supply or not), you'll usually use the DocBook element. To "import" other documents, just use the general external parsed entity mechanism. This is a basic DTD-style XML feature where you use macros like &entityname;. Either find an XML reference or look around our existing DocBook source files for an example to follow. One tricky point is how to include external files verbatim. If you just read in external files as parsed entities, they will be parsed as DocBook source (and therefore they must consist of, at least, legal XML)*. But often you will want to import a real, working file (like a configuration file, sql file, Java source file), and you won't want to hack it up just so you can import it. (For one thing, you shouldn't have to; for another, you may want to provide a link to the file for download, so you wouldn't want people to download a hacked-up version). It would be nice if you could CDATA, then include the entity, but that won't work since the &...; inclusion directive would thereby be escaped. If you don't know what the hell CDATA is, just follow the instructions in the next paragraph. To import a document verbatim, define an external parsed entity for the file ../../docwork/BOOKNAME/cdata/file.name, where BOOKNAME is your book name and file.name is the name of the file to be imported (which resides in the current directory). If you want to know, what will happen is, the Ant build will copy the file-to-be-imported to the directory .../docwork/BOOKNAME/cdata and will sandwich it in a CDATA directive. If you want to provide a link to the document, you just ulink to the document in the current directory, not to the one in the cdata POSTNOTE: The long-term way to do this is with XInclude, or some other generic XML inclusion mechanism. Unfortunately, none of the good methods work with the Java ports of DocBook! ======================================================================= CONVENTIONS Please use elements to mark up notes for yourself or for other developers. All s should be removed before the doc goes public! Please capitalize HSQLDB like "Hsqldb" in titles, and capitalize like "HSQLDB" elsewhere. (In filepaths and package names you code as required for the filepath or package name, of course). ======================================================================= TIPS When closing DocBook and elements, make sure that there is no line break after the text to display and before the closing or tag. Otherwise the resultant display will not look right. Don't capitalize words or phrases to emphasize them (including in section titles or headings). If you want to emphasize something a certain way, then use a DocBook emphasis role, and leave the presentation decisions to the style sheets. It is very easy to set a CSS style to capitalize headings if you want them to appear that way. * Theoretically it would be better and SHOULD be simpler to use unparsed entities for this purpose, but unparsed entities are a messy legacy feature of DTD which is more convoluted than the strategy described here. hsqldb-1.8.0.10.orig/docsrc/guide/0000755000175000017500000000000010416761742015201 5ustar renerenehsqldb-1.8.0.10.orig/docsrc/guide/deployment.xml0000644000175000017500000005617610261455113020110 0ustar renerene Deployment Issues Fred Toussi HSQLDB Development Group ft@cluedup.com $Revision: 1.3 $ $Date: 2005/07/02 09:11:39 $ Hsqldb Guide Copyright 2005 Fred Toussi.

                Purpose Many questions repeatedly asked in Forums and mailing lists are answered in this guide. If you want to use HSQLDB with your application, you should read this guide. This document covers system related issues. For issues related to SQL see the chapter.
                Mode of Operation and Tables HSQLDB has many modes of operation and features that allow it to be used in very different scenarios. Levels of memory usage, speed and accessibility by different applications are influenced by how HSQLDB is deployed.
                Mode of Operation The decision to run HSQLDB as a separate server process or as an in-process database should be based on the following: When HSQLDB is run as a server on a separate machine, it is isolated from hardware failures and crashes on the hosts running the application. When HSQLDB is run as a server on the same machine, it is isolated from application crashes and memory leaks. Server connections are slower than in-process connections due to the overhead of streaming the data for each JDBC call.
                Tables TEXT tables are designed for special applications where the data has to be in an interchangeable format, such as CSV. TEXT tables should not be used for routine storage of data. MEMORY tables and CACHED tables are generally used for data storage. The difference between the two is as follows: The data for all MEMORY tables is read from the .script file when the database is started and stored in memory. In contrast the data for cached tables is not read into memory until the table is accessed. Furthermore, only part of the data for each CACHED table is held in memory, allowing tables with more data than can be held in memory. When the database is shutdown in the normal way, all the data for MEMORY tables is written out to the disk. In comparison, the data in CACHED tables that has changed is written out at shutdown, plus a compressed backup of all the data in all cached tables. The size and capacity of the data cache for all the CACHED tables is configurable. This makes it possible to allow all the data in CACHED tables to be cached in memory. In this case, speed of access is good, but slightly slower than MEMORY tables. For normal applications it is recommended that MEMORY tables are used for small amounts of data, leaving CACHED tables for large data sets. For special applications in which speed is paramount and a large amount of free memory is available, MEMORY tables can be used for large tables as well
                Large Objects JDBC Clobs are supported as columns of the type LONGVARCHAR. JDBC Blobs are supported as columns of the type LONGVARBINARY. When large objects (LONGVARCHAR, LONGVARBINARY, OBJECT) are stored with table definitions that contain several normal fields, it is better to use two tables instead. The first table to contain the normal fields and the second table to contain the large object plus an identity field. Using this method has two benefits. (a) The first table can usually be created as a MEMORY table while only the second table is a CACHED table. (b) The large objects can be retrieved individually using their identity, instead of getting loaded into memory for finding the rows during query processing. An example of two tables and a select query that exploits the separation between the two follows: CREATE MEMORY TABLE MAINTABLE(MAINID INTEGER, ......); CREATE CACHED TABLE LOBTABLE(LOBID INTEGER, LOBDATA LONGVARBINARY); SELECT * FROM (SELECT * FROM MAINTABLE <join any other table> WHERE <various conditions apply>) JOIN LOBTABLE ON MAINID=LOBID; The inner SELECT finds the required rows without reference to the LOBTABLE and when it has found all the rows, retrieves the required large objects from the LOBTABLE.
                Deployment context The files used for storing HSQLDB database data are all in the same directory. New files are always created and deleted by the database engine. Two simple principles must be observed: The Java process running HSQLDB must have full privileges on the directory where the files are stored. This include create and delete privileges. The file system must have enough spare room both for the 'permanent' and 'temporary' files. The default maximum size of the .log file is 200MB. The .data file can grow to up to 8GB. The .backup file can be up to 50% of the .data file. The temporary file created at the time of a SHUTDOWN COMPACT can be equal in size to the .data file.
                Memory and Disk Use Memory used by the program can be thought of as two distinct pools: memory used for table data, and memory used for building result sets and other internal operations. In addition, when transactions are used, memory is utilised for storing the information needed for a rollback. Since version 1.7.1, memory use has been significantly reduced compared to previous versions. The memory used for a MEMORY table is the sum of memory used by each row. Each MEMORY table row is a Java object that has 2 int or reference variables. It contains an array of objects for the fields in the row. Each field is an object such as Integer, Long, String, etc. In addition each index on the table adds a node object to the row. Each node object has 6 int or reference variables. As a result, a table with just one column of type INTEGER will have four objects per row, with a total of 10 variables of 4 bytes each - currently taking up 80 bytes per row. Beyond this, each extra column in the table adds at least a few bytes to the size of each row. The memory used for a result set row has fewer overheads (fewer variables and no index nodes) but still uses a lot of memory. All the rows in the result set are built in memory, so very large result sets may not be possible. In server mode databases, the result set memory is released from the server once the database server has returned the result set. In-process databases release the memory when the application program releases the java.sql.ResultSet object. Server modes require additional memory for returning result sets, as they convert the full result set into an array of bytes which is then transmitted to the client. When UPDATE and DELETE queries are performed on CACHED tables, the full set of rows that are affected, including those affected due to ON UPDATE actions, is held in memory for the duration of the operation. This means it may not be possible to perform deletes or updates involving very large numbers of rows of CACHED tables. Such operations should be performed in smaller sets. When transactions support is enabled with SET AUTOCOMMIT OFF, lists of all insert, delete or update operations are stored in memory so that they can be undone when ROLLBACK is issued. Transactions that span hundreds of modification to data will take up a lot of memory until the next COMMIT or ROLLBACK clears the list. Most JVM implementations allocate up to a maximum amount of memory (usually 64 MB by default). This amount is generally not adequate when large memory tables are used, or when the average size of rows in cached tables is larger than a few hundred bytes. The maximum amount of allocated memory can be set on the java ... command line that is used for running HSQLDB. For example, with Sun JVM version 1.3.0 the parameter -Xmx256m increases the amount to 256 MB. 1.8.0 uses a fast cache for immutable objects such as Integer or String that are stored in the database. In most circumstances, this reduces the memory footprint still further as fewer copies of the most frequently-used objects are kept in memory.
                Cache Memory Allocation With CACHED tables, the data is stored on disk and only up to a maximum number of rows are held in memory at any time. The default is up to 3*16384 rows. The hsqldb.cache_scale database property can be set to alter this amount. As any random subset of the rows in any of the CACHED tables can be held in the cache, the amount of memory needed by cached rows can reach the sum of the rows containing the largest field data. For example if a table with 100,000 rows contains 40,000 rows with 1,000 bytes of data in each row and 60,000 rows with 100 bytes in each, the cache can grow to contain nearly 50,000 rows, including all the 40,000 larger rows. An additional property, hsqldb.cache_size_scale can be used in conjunction with the hsqldb.cache_scale property. This puts a limit in bytes on the total size of rows that are cached. When the default values is used for both properties, the limit on the total size of rows is approximately 50MB. (This is the size of binary images of the rows and indexes. It translates to more actual memory, typically 2-4 times, used for the cache because the data is represented by Java objects.) If memory is limited, the hsqldb.cache_scale or hsqldb.cache_size_scale database properties can be reduced. In the example above, if the hsqldb.cache_size_scale is reduced from 10 to 8, then the total binary size limit is reduced from 50MB to 12.5 MB. This will allow the number of cached rows to reach 50,000 small rows, but only 12,500 of the larger rows.
                Managing Database Connections In all running modes (server or in-process) multiple connections to the database engine are supported. In-process (standalone) mode supports connections from the client in the same Java Virtual Machine, while server modes support connections over the network from several different clients. Connection pooling software can be used to connect to the database but it is not generally necessary. With other database engines, connection pools are used for reasons that may not apply to HSQLDB. To allow new queries to be performed while a time-consuming query is being performed in the background. This is not possible with HSQLDB 1.8.0 as it blocks while performing the first query and deals with the next query once it has finished it. This capability is under development and will be introduced in a future version. To limit the maximum number of simultaneous connections to the database for performance reasons. With HSQLDB this can be useful only if your application is designed in a way that opens and closes connections for each small task. To control transactions in a multi-threaded application. This can be useful with HSQLDB as well. For example, in a web application, a transaction may involve some processing between the queries or user action across web pages. A separate connection should be used for each HTTP session so that the work can be committed when completed or rolled back otherwise. Although this usage cannot be applied to most other database engines, HSQLDB is perfectly capable of handling over 100 simultaneous HTTP sessions as individual JDBC connections. An application that is not both multi-threaded and transactional, such as an application for recording user login and logout actions, does not need more than one connection. The connection can stay open indefinitely and reopened only when it is dropped due to network problems. When using an in-process database with versions prior to 1.7.2 the application program had to keep at least one connection to the database open, otherwise the database would have been closed and further attempts to create connections could fail. This is not necessary since 1.7.2, which does not automatically close an in-process database that is opened by establishing a connection. An explicit SHUTDOWN command, with or without an argument, is required to close the database. In version 1.8.0 a connection property can be used to revert to the old behaviour. When using a server database (and to some extent, an in-process database), care must be taken to avoid creating and dropping JDBC Connections too frequently. Failure to observe this will result in unsuccessful connection attempts when the application is under heavy load.
                Upgrading Databases Any database not produced with the release version of HSQLDB 1.8.0 must be upgraded to this version. This includes databases created with the RC versions of 1.8.0. The instructions under the section should be followed in all cases. Once a database is upgraded to 1.8.0, it can no longer be used with Hypersonic or previous versions of HSQLDB. There may be some potential legacy issues in the upgrade which should be resolved by editing the .script file: Version 1.8.0 does not accept duplicate names for indexes that were allowed before 1.7.2. Version 1.8.0 does not accept duplicate names for table columns that were allowed before 1.7.0. Version 1.8.0 does not create the same type of index for foreign keys as versions before 1.7.2. Version 1.8.0 does not accept table or column names that are SQL identifiers without double quoting.
                Upgrading Using the SCRIPT Command To upgrade from 1.7.2 or 1.7.3 to 1.8.0, simply issue the SET SCRIPTFORMAT TEXT and SHUTDOWN SCRIPT commands with the old version, then open with the new version of the engine. The upgrade is then complete. To upgrade from older version database files (1.7.1 and older) that do not contain CACHED tables, simple SHUTDOWN with the older version and open with the new version. If there is any error in the .script file, try again after editing the .script file. To upgrade from older version database files (1.7.1 and older) that contain CACHED tables, use the SCRIPT procedure below. In all versions of HSQLDB and Hypersonic 1.43, the SCRIPT 'filename' command (used as an SQL query) allows you to save a full record of your database, including database object definitions and data, to a file of your choice. You can export a script file using the old version of the database engine and open the script as a database with 1.8.0. Upgrade Using SCRIPT procedure Open the original database in the old version of DatabaseManager Issue the SCRIPT command, for example SCRIPT 'newversion.script' to create a script file containing a copy of the database. Use the 1.8.0 version of DatabaseManager to create a new database, in this example 'newversion' in a different directory. SHUTDOWN this database. Copy the newversion.script file from step 2 over the file of the same name for the new database created in 4. Try to open the new database using DatabaseManager. If there is any inconsistency in the data, the script line number is reported on the console and the opening process is aborted. Edit and correct any problems in the newversion.script before attempting to open again. Use the guidelines in the next section (Manual Changes to the .script File). Use a programming editor that is capable of handling very large files and does not wrap long lines of text.
                Manual Changes to the .script File In 1.8.0 the full range of ALTER TABLE commands is available to change the data structures and their names. However, if an old database cannot be opened due to data inconsistencies, or the use of index or column names that are not compatible with 1.8.0, manual editing of the SCRIPT file can be performed. The following changes can be applied so long as they do not affect the integrity of existing data. Names of tables, columns and indexes can be changed. CREATE UNIQUE INDEX ... to CREATE INDEX ... and vice versa A unique index can always be converted into a normal index. A non-unique index can only be converted into a unique index if the table data for the column(s) is unique in each row. NOT NULL A not-null constraint can always be removed. It can only be added if the table data for the column has no null values. PRIMARY KEY A primary key constraint can be removed or added. It cannot be removed if there is a foreign key referencing the column(s). COLUMN TYPES Some changes to column types are possible. For example an INTEGER column can be changed to BIGINT, or DATE, TIME and TIMESTAMP columns can be changed to VARCHAR. After completing the changes and saving the modified *.script file, you can open the database as normal.
                Backing Up Databases The data for each database consists of up to 5 files in the same directory. The endings are *.properties, *.script, *.data, *.backup and *.log (a file with the *.lck ending is used for controlling access to the database and should not be backed up). These should be backed up together. The files can be backed up while the engine is running but care should be taken that a CHECKPOINT or SHUTDOWN operation does not take place during the backup. It is more efficient to perform the backup immediately after a CHECKPOINT. The *.data file can be excluded from the backup. In this case, when restoring, a dummy *.data file is needed which can be an empty, 0 length file. The engine will expand the *.backup file to replace this dummy file if the backup is restored. If the *.data file is not backed up, the *.properties file may have to be modified to ensure it contain modified=yes instead of modified=no prior to restoration. If a backup immediately follows a checkpoint, then the *.log file can also be excluded, reducing the significant files to *.properties, *.script and *.backup. Normal backup methods, such as archiving the files in a compressed bundle can be used.

                Purpose, Coverage, Changes in Behavior Purpose This document explains how to use SqlTool, the main purpose of which is to read your SQL text file or stdin, and execute the SQL commands therein against a JDBC database. There are also a great number of features to facilitate both interactive use and automation. The following paragraphs explain in a general way why SqlTool is better than any existing tool for text-mode interactive SQL work, and for automated SQL tasks. Two important benefits which SqlTool shares with other pure Java JDBC tools is that users can use a consistent interface and syntax to interact with a huge variety of databases-- any database which supports JDBC; plus the tool itself runs on any Java platform. Instead of using isql for Sybase, psql for Postgresql, Sql*plus for Oracle, etc., you can use SqlTool for all of them. As far as I know, SqlTool is the only production-ready, pure Java, command-line, generic JDBC client. Several databases come with a command-line client with limited JDBC abilities (usually designed for use with their specific database). SqlTool is purposefully not a Gui tool like Toad or DatabaseManager. There are many use cases where a Gui SQL tool would be better. Where automation is involved in any way, you really need a text client to at least test things properly and usually to prototype and try things out. A command-line tool is really better for executing SQL scripts, any form of automation, direct-to-file fetching, and remote client usage. To clarify this last, if you have to do your SQL client work on a work server on the other side of a VPN connection, you will quickly appreciate the speed difference between text data transmission and graphical data transmission, even if using VNC or Remote Console. Another case would be where you are doing some repetitive or very structured work where variables or language features would be useful. Gui proponents may disagree with me, but scripting (of any sort) is more efficient than repetitive copy & pasting with a Gui editor. SqlTool starts up very quickly, and it takes up a tiny fraction of the RAM required to run a comparably complex Gui like Toad. SqlTool is superior for interactive use because over many years it has evolved lots of features proven to be efficient for day-to-day use. Three concise help commands (\?, :?, and *?) list all available commands of the corresponding type. SqlTool doesn't support up-arrow or other OOB escapes (due to basic Java I/O limitations), but it more than makes up for this limitation with aliases, user variables, command-line history and recall, and command-line editing with extended Perl/Java regular expressions. The \d commands deliver JDBC metadata information as consistently as possible (in several cases, database-specific work-arounds are used to obtain the underlying data even though the database doesn't provide metadata according to the JDBC specs). Unlike server-side language features, the same feature set works for any database server. Database access details may be supplied on the command line, but day-to-day users will want to centralize JDBC connection details into a single, protected RC file. You can put connection details (username, password, URL, and other optional settings) for scores of target databases into your RC file, then connect to any of them whenever you want by just giving SqlTool the ID ("urlid") for that database. When you Execute SqlTool interactively, it behaves by default exactly as you would want it to. If errors occur, you are given specific error messages and you can decide whether to roll back your session. You can easily change this behavior to auto-commit, exit-upon-error, etc., for the current session or for all interactive invocations. You can import or export delimiter-separated-value files. When you Execute SqlTool with a SQL script, it behaves by default exactly as you would want it to. If any error is encountered, the connection will be rolled back, then SqlTool will exit with an error exit value. If you wish, you can detect and handle error (or other) conditions yourself. For scripts expected to produce errors (like many scripts provided by database vendors), you can have SqlTool continue-upon-error. For SQL script-writers, you will have access to portable scripting features which you've had to live without until now. You can use variables set on the command line or in your script. You can handle specific errors based on the output of SQL commands or of your variables. You can chain SQL scripts, invoke external programs, dump data to files, use prepared statements, Finally, you have a procedural language with if, foreach, while, continue, and break statements.
                Platforms and SqlTool versions covered SqlTool runs on any Java 1.4 or later platform. I haven't run it with a non-Sun JVM in years (like Blackdown, IBM, JRockit, etc.), but I've had no reports of problems with them, and SqlTool uses none of the Sun-proprietary classes directly. Some of the examples below use quoting which works exactly as-is for any Bourne-compatible UNIX shell. (Only line-continuation would need to be changed for C-compatible UNIX shells). I have not yet tested these commands on Windows, and I doubt whether the quoting will work just like this (though it is possible). SqlTool is still a very useful tool even if you have no quoting capability at all. If you are using SqlTool from a HSQLDB distribution before version 1.8.0.8 final, you should use the documentation with that distribution, because this manual documents many new features, several significant changes to interactive-only commands, and a few changes effecting backwards-compatibility (see next section about that). This document is now updated for the current versions of SqlTool and SqlFile at the time I am writing this (versions 333 and 354 correspondingly, SqlFile is the class which does most of the work for SqlTool). Therefore, if you are using a version of SqlTool or SqlFile that is more than a couple revisions greater, you should find a newer version of this document. (The imprecision is due to content-independent revision increments at build time, and the likelihood of one or two behavior-independent bug fixes after public releases). The startup banner will report both versions when you run SqlTool interactively. (Dotted version numbers of SqlTool and SqlFile are older than 333 and 354). This guide covers SqlTool bundled with series 1.8 and 1.9 of HSQLDB. To reduce the time I will need to spend maintaining this document, in this chapter I am giving the path to the sample directory as it is in HSQLDB 1.9.x distributions, namely, HSQLDB_HOME/sample. HSQLDB 1.8.x users should translate these sample directory paths to use HSQLDB_HOME/src/org/hsqldb/sample/....
                Functional Changes This section lists changes to SqlTool since the last major release of HSQLDB which may effect the portability of SQL scripts. For this revision of this document, this list consists of script-impacting changes made to SqlTool after the final 1.8.0.0 HSQLDB release. I'm specifically not listing changes to interactive-only commands (":" commands, with one legacy exception which is listed below), since these commands can't be used in SQL scripts; and I'm specifically not listing backwards-compatible feature additions and enhancements. The reason for limiting the change list to only portability- impacting changes is that a list of all enhancements since just 1.8.0.0 would be pages long. SqlTool now consistently outputs \r\n line breaks when on \r\n-linebreak platforms, like Windows. This includes output written to stdout, \w files, and \o files. Time type values are always output with the date as well as the time. This was required in order to produce consistent output for the wildly varying formats provided by different database vendors. DSV input now takes JDBC Timestamp format with date and optionally time of day. The command ":;" is now strictly an interactive command. If you want to repeat a command in an SQL scripts, just repeat the exact text of the command. Non-interactive use now has no dependency on command history. The command ":w" has replace the command \w. Unlike writing "output" to a file with \w, :w is used to write SQL "commands", and this is an interactive feature. Shell scripts using raw mode (e.g. PL/SQL scripts) must terminate the raw code with a line containing ".;", which will also send the code to the database for execution. (The old "." command has been changed to ":." to make it very clear that the command is now an interactive command). The --sql argument will never automatically append a semicolon to the text you provide. If you want to execute a command ending with a semi-- then type a semi. Although it doesn't effect scripts, I will mention a significant recent change to interactive commands. Special and PL commands are not stored to the edit buffer and to command history, so they can be recalled and edited just like SQL commands. Now, only edit/history : commands are not stored to the buffer and history.
                The Bare Minimum You Need to Know to Run SqlTool The Bare Minimum If you are using an Oracle database server, it will commit your current transaction if you cleanly disconnect, regardless of whether you have set auto-commit or not. This will occur if you exit SqlTool (or any other client) in the normal way (as opposed to killing the process or using Ctrl-C, etc.). This is mentioned in this section only for brevity, so I don't need to mention it in the main text in the many places where auto-commit is discussed. This behavior has nothing to do with SqlTool. It is a quirk of Oracle. If you want to use SqlTool, then you either have an SQL text file, or you want to interactively type in SQL commands. If neither case applies to you, then you are looking at the wrong program. To run SqlTool... Copy the file sqltool.rc from the directory sample of your HSQLDB distribution to your home directory and secure access to it if your computer is accessible to anybody else (most likely from the network). This file will work as-is for a Memory Only database instance; or if your target is a HSQLDB Server running on your local computer with default settings and the password for the "sa" account is blank (the sa password is blank when new HSQLDB database instances are created). Edit the file if you need to change the target Server URL, username, password, character set, JDBC driver, or TLS trust store as documented in the section. (You could, alternatively, use the --inlineRc command-line switch to specify your connection parameters as documented in the section). Find out where your hsqldb.jar file resides. It typically resides at HSQLDB_HOME/lib/hsqldb.jar where HSQLDB_HOME is the base directory of your HSQLDB software installation. For this reason, I'm going to use "$HSQLDB_HOME/lib/hsqldb.jar" as the path to hsqldb.jar for my examples, but understand that you need to use the actual path to your own hsqldb.jar file. Run java -jar $HSQLDB_HOME/lib/hsqldb.jar --help to see what command-line arguments are available. Note that you don't need to worry about setting the CLASSPATH when you use the -jar switch to java. Assuming that you set up your SqlTool RC file at the default location and you want to use the HSQLDB JDBC driver, you will want to run something like java -jar $HSQLDB_HOME/lib/hsqldb.jar mem for interactive use, or java -jar $HSQLDB_HOME/lib/hsqldb.jar --sql 'SQL statement;' mem or java -jar $HSQLDB_HOME/lib/hsqldb.jar mem filepath1.sql... where mem is an urlid, and the following arguments are paths to text SQL files. For the filepaths, you can use whatever wildcards your operating system shell supports. The urlid mem in these commands is a key into your RC file, as explained in the section. Since this is a Memory Only database, you can use SqlTool with this urlid immediately with no database setup whatsoever (however, you can't persist any changes that you make to this database). The sample sqltool.rc file also defines the urlid "localhost-sa" for a local HSQLDB Server. At the end of this section, I explain how you can load some sample data to play with, if you want to. SqlTool does not commit SQL changes by default. This leaves it to the user's disgression whether to commit or rollback their modifications. Remember to either run \= to commit before quitting SqlTool (most databases also support the SQL command commit;, or use the --autoCommit command-line switch. If you put a file named auto.sql into your home directory, this file will be executed automatically every time that you run SqlTool interactively and without the --noAutoFile switch. To use a JDBC Driver other than the HSQLDB driver, you can't use the -jar switch because you need to modify the classpath. You must add the hsqldb.jar file and your JDBC driver classes to your classpath, and you must tell SqlTool what the JDBC driver class name is. The latter can be accomplished by either using the "--driver" switch, or setting "driver" in your config file. The section. explains the second method. Here's an example of the first method (after you have set the classpath appropriately). java org.hsqldb.util.SqlTool --driver oracle.jdbc.OracleDriver urlid If the tables of query output on your screen are all messy because of lines wrapping, the best and easiest solution is usually to resize your terminal emulator window to make it wider. (With some terms you click & drag the frame edges to resize, with others you use a menu system where you can enter the number of columns). If you are using SqlTool to connect to a HSQLDB network server or any non-HSQLDB database, you may prefer to use the jar file hsqltool.jar or hsqldbutil.jar instead of hsqldb.jar. These alternative jar files contain all of SqlTool without stuff you don't need, but you will have to follow a simple procedure to generate these jars. See the section.
                Non-displayable Types There are many SQL types which SqlTool (being a text-based program) can't display properly. This includes the SQL types BLOB, JAVA_OBJECT, STRUCT, and OTHER. When you run a query that returns any of these, SqlTool will save the very first such value obtained to the binary buffer and will not display any output from this query. You can then save the binary value to a file, as explained in the section. There are other types, such as BINARY, which JDBC can make displayable (by using ResultSet.getString()), but which you may very well want to retrieve in raw binary format. You can use the \b command to retrieve any-column-type-at-all in raw binary format (so you can later store the value to a binary file). Another restriction which all text-based database clients have is the practical inability for the user to type in binary data such as photos, audio streams, and serialized Java objects. You can use SqlTool to load any binary object into a database by telling SqlTool to get the insert/update datum from a file. This is also explained in the section.
                Desktop shortcuts Desktop shortcuts and quick launch icons are useful, especially if you often run SqlTool with the same set of arguments. It's really easy to set up several of them-- one for each way that you invoke SqlTool (i.e., each one would start SqlTool with all the arguments for one of your typical startup needs). One typical setup is to have one shortcut for each database account which you normally use (use a different urlid argument in each shortcut's Target specification. Desktop icon setup varies depending on your Desktop manager, of course. I'll explain how to set up a SqlTool startup icon in Windows XP. Linux and Mac users should be able to take it from there, since it's easier with the common Linux and Mac desktops. Creating a Desktop Shortcut for SqlTool Right click in the main Windows background. New Shortcut Browse Navigate to where your good JRE lives. For recent Sun JRE's, it installs to C:\Program Files\Java\*\bin by default (the * will be a JDK or JRE name and version number). Select java.exe. OK Next Enter any name Finish Right click the new icon. Properties Edit the Target field. Leave the path to java.exe exactly as it is, including the quotes, but append to what is there. Beginning with a space, enter the command-line that you want run. Change Icon... to a pretty icon. If you want a quick-launch icon instead of (or in addition to) a desktop shortcut icon, click and drag it to your quick launch bar. (You may or may not need to edit the Windows Toolbar properties to let you add new items).
                Loading sample data If you want some sample database objects and data to play with, execute the sampledata.sql SQL file. sampledata.sql resides in the sample directory of your HSQLDB distribution . To separate the sample data from your regular data, you can put it into its own schema by running this before you import: CREATE SCHEMA sampledata AUTHORIZATION dba; SET SCHEMA sampledata; Run it like this from an SqlTool session \i HSQLDB_HOME/sample/sampledata.sql where HSQLDB_HOME is the base directory of your HSQLDB software installation . For memory-only databases, you'll need to run this every time that you run SqlTool. For other (persistent) databases, the data will reside in your database until you drop the tables.
                RC File Authentication Setup RC file authentication setup is accomplished by creating a text RC configuration file. In this section, when I say configuration or config file, I mean an RC configuration file. RC files can be used by any JDBC client program that uses the org.hsqldb.util.RCData class-- this includes SqlTool, DatabaseManager, DatabaseManagerSwing. You can use it for your own JDBC client programs too. The following sample RC file resides at sample/sqltool.rc in your HSQLDB distribution . Sample RC File &sqltool.rc-cdata; You can put this file anywhere you want to, and specify the location to SqlTool/DatabaseManager/DatabaseManagerSwing by using the --rcfile argument. If there is no reason to not use the default location (and there are situations where you would not want to), then use the default location and you won't have to give --rcfile arguments to SqlTool/DatabaseManager/DatabaseManagerSwing. The default location is sqltool.rc or dbmanager.rc in your home directory (corresponding to the program using it). If you have any doubt about where your home directory is, just run SqlTool with a phony urlid and it will tell you where it expects the configuration file to be. java -jar $HSQLDB_HOME/lib/hsqldb.jar x The config file consists of stanza(s) like this: urlid web url jdbc:hsqldb:hsql://localhost username web password webspassword These four settings are required for every urlid. (There are optional settings also, which are described a couple paragraphs down). The URL may contain JDBC connection properties. You can have as many blank lines and comments like # This comment in the file as you like. The whole point is that the urlid that you give in your SqlTool/DatabaseManager command must match a urlid in your configuration file. Use whatever facilities are at your disposal to protect your configuration file. It should be readable, both locally and remotely, only to users who run programs that need it. On UNIX, this is easily accomplished by using chmod/chown commands and making sure that it is protected from anonymous remote access (like via NFS, FTP or Samba). You can also put the following optional settings into a urlid stanza. The setting will, of course, only apply to that urlid. charset This is used by the SqlTool program, but not by the DatabaseManager programs. See the section of the section. You can, alternatively, set this for one SqlTool invocation by setting the system property sqlfile.charset . Defaults to US-ASCII. driver Sets the JDBC driver class name. You can, alternatively, set this for one SqlTool/DatabaseManager invocation by using the command line switch --driver. Defaults to org.hsqldb.jdbcDriver. truststore TLS trust keystore store file path as documented in the chapter. You usually only need to set this if the server is using a non-publicly-certified certificate (like a self-signed self-ca'd cert). Property and SqlTool command-line switches override settings made in the configuration file.
                Using Inline RC Authentication Inline RC authentication setup is accomplished by using the --inlineRc command-line switch on SqlTool. The --inlineRc command-line switch takes a comma-separated list of key/value elements. The url and user elements are required. The rest are optional. url The JDBC URL of the database you wish to connect to. user The username to connect to the database as. charset Sets the character encoding. Defaults to US-ASCII. trust The TLS trust keystore file path as documented in the TLS chapter. password You may only use this element to set empty password, like password= . For any other password value, omit the password element and you will be prompted for the value. (Use the --driver switch instead of --inlineRc to specify a JDBC driver class). Here is an example of invoking SqlTool to connect to a standalone database. java -jar $HSQLDB_HOME/lib/hsqldb.jar --inlineRc URL=jdbc:hsqldb:file:/home/dan/dandb,USER=dan For security reasons, you cannot specify a non-empty password as an argument. You will be prompted for a password as part of the login process.
                Using the current version of SqlTool with an older HSQLDB distribution. This procedure will allow users of a legacy version of HSQLDB to use all of the new features of SqlTool. You will also get the new versions of the DatabaseManagers! This procedure works for distros going back to 1.7.3.3 at least, probably much farther. Follow the instructions in the See the section to build the jar file hsqldbutil.jar. For now on, whenever you are going to run SqlTool, make sure that you have this hsqldbutil.jar as the first item in your CLASSPATH. You can't run SqlTool with the "-jar" switch (because the -jar switch doesn't permit setting your own class path). Here's a UNIX example where somebody wants to use the new SqlTool with their older HSQLDB database, as well as with Postgresql and a local application. CLASSPATH=/path/to/hsqldbutil.jar:/home/bob/classes:/usr/local/lib/pg.jdbc3.jar export CLASSPATH java org.hsqldb.util.SqlTool urlid
                Interactive Usage Do read the section before you read this section. You run SqlTool interactively by specifying no SQL filepaths on the SqlTool command line. Like this. java -jar $HSQLDB_HOME/lib/hsqldb.jar urlid What happens when SqlTool is run interactively (using all default settings) SqlTool starts up and connects to the specified database, using your SqlTool configuration file (as explained in the section). SQL file auto.sql in your home directory is executed (if there is one), SqlTool displays a banner showing the SqlTool and SqlFile version numbers and describes the different command types that you can give, as well as commands to list all of the specific commands available to you. You exit your session by using the "\q" special command or ending input (like with Ctrl-D or Ctrl-Z). Every command (regardless of type) and comment must begin at the beginning of a line (or immediately after a comment ends with "*/"). You can't nest commands or comments. You can only start new commands (and comments) after the preceding statement has been terminated. (Remember that if you're running SqlTool interactively, you can terminate an SQL statement without executing it by entering a blank line). (Special Commands, Edit Buffer Commands and PL Commands always consist of just one line. Any of these commands or comments may be preceded by space characters.) These rules do not apply at all to . Raw mode is for use by advanced users when they want to completely bypass SqlTool processing in order to enter a chunk of text for direct transmission to the database engine.
                Command Types When you are typing into SqlTool, you are always typing part of the immediate command. You execute the immediate command by hitting ENTER after a semi-colon (for SQL commands) or by just hitting ENTER (after any other non-empty command-- see next section about this distinction). The interactive : commands can perform actions with or on the edit buffer. The edit buffer usually contains a copy of the last command executed, and you can always view it with the :b command. If you never use any : commands, you can entirely ignore the edit buffer. If you want to repeat commands or edit previous commands, you will need to work with the edit buffer. The immediate command contains whatever (and exactly what) you type. The command history and edit buffer may contain any type of command other than comments and : commands (i.e., : commands and comments are just not copied to the history or to the edit buffer). Hopefully an example will clarify the difference between the immediate command and the edit buffer. If you type in the edit buffer Substitution command ":s/tbl/table/", the :s command that you typed is the immediate command (and it will never be stored to the edit buffer or history, since it is a : command), but the purpose of the substitution command is to modify the contents of the edit buffer (perform a substitution on it)-- the goal being that after your substitutions you would execute the buffer with the ":;" command. The ":a" command is special in that when you hit ENTER to execute it, it copies the contents of the edit buffer to a new immediate command and leaves you in a state where you are appending to that immediate command (nearly) exactly as if you had just typed it in.
                Command Types Command types SQL Statement Any command that you enter which does not begin with "\", ":", or "* " is an SQL Statement. The command is not terminated when you hit ENTER, like most OS shells. You terminate SQL Statements with either ";" at the end of a line, or with a blank line. In the former case, the SQL Statement will be executed against the SQL database and the command will go into the edit buffer and SQL command history for editing or viewing later on. In the former case, execute against the SQL database means to transmit the SQL text to the database engine for execution. In the latter case (you end an SQL Statement with a blank line), the command will go to the edit buffer and SQL history, but will not be executed (but you can execute it later from the edit buffer). (See the note immediately above about multiple SQL statements in one SqlTool command). (Blank lines are only interpreted this way when SqlTool is run interactively. In SQL files, blank lines inside of SQL statements remain part of the SQL statement). As a result of these termination rules, whenever you are entering text that is not a Special Command, Edit Buffer / History Command, or PL Command, you are always appending lines to an SQL Statement or comment. (In the case of the first line, you will be appending to an empty SQL statement. I.e. you will be starting a new SQL Statement or comment). Special Command Run the command "\?" to list the Special Commands. All of the Special Commands begin with "\". I'll describe some of the most useful Special Commands below. Edit Buffer / History Command Run the command ":?" to list the Edit-Buffer/History Commands. All of these commands begin with ":". These commands use commands from the command history, or operate upon the edit "buffer", so that you can edit and/or (re-)execute previously entered commands. PL Command Procedural Langage commands. Run the command "*?" to list the PL Commands. All of the PL Commands begin with "*". PL commands are for setting and using scripting variables and conditional and flow control statements like * if and * while. A few PL features (such as PL aliases and updating and selecing data directly from/to files) can be a real convenience for nearly all users, so these features will be discussed briefly in this section. More detailed explanation of PL variables and the other PL features, with examples, are covered in the section. Raw Mode The descriptions of command-types above do not apply to . In raw mode, SqlTool doesn't interpret what you type at all. It all just goes into the edit buffer which you can send to the database engine. Beginners can safely ignore raw mode. You will never encounter it unless you run the "\." special command, or enter a PL/SQL command. See the section for the details. Above, we said that if you enter an SQL command, one SQL command corresponds to one SqlTool command. This is the most typical usage, however, you can actually put multiple SQL statements into one SQL command. One example would be INSERT INTO t1 VALUES(0); SELECT * FROM t1; This is one SqlTool command containing two SQL statements. See the section to see why you may want to chunk SQL commands, how, and the implications.
                Special Commands Essential Special Commands \? help \q quit \i path/to/script.sql execute the specified SQL script, then continue again interactively. \= commit the current SQL transaction. Most users are used to typing the SQL statement commit;, but this command is crucial for those databases which don't support the statement. It's obviously unnecessary if you have auto-commit mode on. \x? List a summary of DSV eXporting, and all available DSV options. \m? List a summary of DSV iMporting, and all available DSV options. \d? List a summary of the \d commands below. \dt [filter_substring] \dv [filter_substring] \ds [filter_substring] \di [table_name] \dS [filter_substring] \da [filter_substring] \dn [filter_substring] \du [filter_substring] \dr [filter_substring] \d* [filter_substring] Lists available objects of the given type. t: non-system Tables v: Views s: Sequences i: Indexes S: System tables a: Aliases n: schema Names u: database Users r: Roles *: all table-like objects If your database supports schemas, then the schema name will also be listed. If you supply an optional filter substring, then only items which contain the given substring (in the object name or schema name) will be listed. The substring test is case-sensitive! Even though in SQL queries and for the "\d objectname" command object names are usually case-insensitive, for the \dX commands, you must capitalize the filter substring exactly as it will appear in the special command output. This is an inconvenience, since the database engine will change names in SQL to default case unless you double-quote the name, but that is server-side functionality which cannot (portably) be reproduced by SqlTool. You can use spaces and other special characters in the string. Filter substrings ending with "." are special. If a substring ends with ".", then this means to narrow the search by the exact, case-sensitive schema name given. For example, if I run "\d* BLAINE.", this will list all table-like database objects in the "BLAINE" schema. The capitalization of the schema must be exactly the same as how the schema name is listed by the "\dn" command. You can use spaces and other special characters in the string. (I.e., enter the name exactly how you would enter it inside of double-quotes in an SQL command). This is an inconvenience, since the database engine will change names in SQL to default case unless you double-quote the name, but that is server-side functionality which cannot (portably) be reproduced by SqlTool. Indexes may not be searched for by substring, only by exact target table name. So if I1 is an index on table T1, then you list this index by running "\di T1". In addition, many database vendors will report on indexes only if a target table is identified. Therefore, "\di" with no argument will fail if your database vendor does not support it. \d objectname [filter] Lists names of columns in the specified table or view. objectname may be a base table name or a schema.object name. If you supply a filter string, then only columns with a name containing the given filter will be listed. The objectname is nearly always case-insensitive (depends on your database), but the filter is always case-sensitive. You'll find this filter is a great convenience compared to other database utilities, where you have to list all columns of large tables when you are only interested in one of them. When working with real data (as opposed to learning or playing), I often find it useful to run two SqlTool sessions in two side-by-side terminal emulator windows. I do all of my real work in one window, and use the other mostly for \d commands. This way I can refer to the data dictionary while writing SQL commands, without having to scroll. This list here includes only the essential Special Commands, but n.b. that there are other useful Special Commands which you can list by running \?. (You can, for example, execute SQL from external SQL files, and save your interactive SQL commands to files). Some specifics of these other commands are specified immediately below, and the section explains how to use the "\o" and "\H" special commands to generate reports. Be aware that the \! Special Command does not work for external programs that read from standard input. You can invoke non-interactive and graphical interactive programs, but not command-line interactive programs. SqlTool executes \! programs directly, it does not run an operating system shell (this is to avoid OS-specific code in SqlTool). Because of this, you can give as many command-line arguments as you wish, but you can't use shell wildcards or redirection. The \w command can be used to store any command in your SQL history to a file. Just restore the command to the edit buffer with a command like "\-4" before you give the \w command.
                Edit Buffer / History Commands Edit Buffer / History Commands :? help :b List the current contents of the edit buffer. :h Shows the Command History. For each command which has been executed (up to the max history length), the SQL command history will show the command; its command number (#); and also how many commands back it is (as a negative number). : commands are never added to the history list. You can then use either form of the command identifier to recall a command to the edit buffer (the command described next) or as the target of any of the following : commands. This last is accomplished in a manner very similar to the vi editor. You specify the target command number between the colon and the command. As an example, if you gave the command :s/X/Y/, that would perform the substitution on the contents of the edit buffer; but if you gave the command :-3 s/X/Y/, that would perform the substitution on the command 3 back in the command history (and copy the output to the edit buffer). Also, just like vi, you can identify the command to recall by using a regular expression inside of slashes, like :/blue/ s/X/Y/ to operate on the last command you ran which contains "blue". :13 OR :-2 OR :/blue/ Recalls a command from Command history to the edit buffer. Enter ":" followed by the positive command number from Command history, like ":13"... or ":" followed by a negative number like ":-2" for two commands back in the Command history... or ":" followed by a regular expression inside slashes, like ":/blue/" to recall the last command which contains "blue". The specified command will be written to the edit buffer so that you can execute it or edit it using the commands below. As described under the :h command immediately above, you can follow the command number here with any of the commands below to perform the given operation on the specified command from history instead of on the edit buffer contents. So, for example, ":4;" would load command 4 from history then execute it (see the ":;" command below). :; Executes the SQL, Special or PL statement in the edit buffer (by default). This is an extremely useful command. It's easy to remember because it consists of ":", meaning Edit Buffer Command, plus a line-terminating ";", (which generally means to execute an SQL statement, though in this case it will also execute a special or PL command). :a Enter append mode with the contents of the edit buffer (by default) as the current command. When you hit ENTER, things will be exactly as if you physically re-typed the command that is in the edit buffer. Whatever lines you type next will be appended to the immediate command. As always, you then have the choice of hitting ENTER to execute a Special or PL command, entering a blank line to store back to the edit buffer, or end a SQL statement with semi-colon and ENTER to execute it. You can, optionally, put a string after the :a, in which case things will be exactly as just described except the additional text will also be appended to the new immediate command. If you put a string after the :a which ends with ;, then the resultant new immediate command will just be executed right away, as if you typed in and entered the entire thing. If your edit buffer contains SELECT x FROM mytab and you run a:le, the resultant command will be SELECT x FROM mytable. If your edit buffer contains SELECT x FROM mytab and you run a: ORDER BY y, the resultant command will be SELECT x FROM mytab ORDER BY y. Notice that in the latter case the append text begins with a space character. :s/from regex/to string/switches The Substitution Command is the primary method for SqlTool command editing-- it operates upon the current edit buffer by default. The "to string" and the "switches" are both optional (though the final "/" is not). To start with, I'll discuss the use and behavior if you don't supply any substitution mode switches. Don't use "/" if it occurs in either "from string" or "to string". You can use any character that you want in place of "/", but it must not occur in the from or to strings. Example :s@from string@to string@ The to string is substituted for the first occurrence of the (case-specific) from string. The replacement will consider the entire SQL statement, even if it is a multi-line statement. In the example above, the from regex was a plain string, but it is interpreted as a regular expression so you can do all kinds of powerful substitutions. See the perlre man page, or the java.util.regex.Pattern API Spec for everything you need to know about extended regular expressions. Don't end a to string with ";" in attempt to make a command execute. There is a substitution mode switch to use for that purpose. You can use any combination of the substitution mode switches. Use "i" to make the searches for from regex case insensitive. Use "g" to substitute Globally, i.e., to subsitute all occurrences of the from regex instead of only the first occurrence found. Use ";" to execute the command immediately after the substitution is performed. Use "m" for ^ and $ to match each line-break in a multi-line edit buffer, instead of just at the very beginning and every end of the entire buffer. If you specify a command number (from the command history), you end up with a feature very reminiscent of vi, but even more powerful, since the Perl/Java regular expression are a superset of the vi regular expressions. As an example, :24 s/pin/needle/g; would start with command number 24 from command history, substitute "needle" for all occurrences of "pin", then execute the result of that substitution (and this final statement will of course be copied to the edit buffer and to command history). :w /path/to/file.sql This appends the contents of the current buffer (by default) to the specified file. Since what is being written are Special, PL, or SQL commands, you are effectively creating an SQL script. I find the ":/regex/" and ":/regex/;" constructs particularly handy for every-day usage. :/\\d/; re-executes the last \d command that you gave (The extra "\" is needed to escape the special meaning of "\" in regular expressions). It's great to be able to recall and execute the last "insert" command, for example, without needing to check the history or keep track of how many commands back it was. To re-execute the last insert command, just run ":/insert/;". If you want to be safe about it, do it in two steps to verify that you didn't accidentally recall some other command which happened to contain the string "insert", like :/insert/ :;(Executing the last only if you are satisfied when SqlTool reports what command it restored). Often, of course, you will want to change the command before re-executing, and that's when you combine the :s and :a commands. We'll finish up with a couple fine points about Edit/Buffer commands. You generally can't use PL variables in Edit/Buffer commands, to eliminate possible ambiguities and complexities when modifying commands. The :w command is an exception to this rule, since it can be useful to use variables to determine the output file, and this command does not do any "editing". The :? help explains how you can change the default regular expression matching behavior (case sensitivity, etc.), but you can always use syntax like "(?i)" inside of your regular expression, as described in the Java API spec for class java.util.regex.Pattern, found here. History-command-matching with the /regex/ construct is purposefully liberal, matching any portion of the command, case sensitive, etc., but you can still use the method just described to modify this behavior. In this case, you could use "(?-i)" at the beginning of your regular expression to be case-sensitive.
                PL Commands Essential PL Command * VARNAME = value Set the value of a variable. If the variable doesn't exist yet, it will be created. The most common use for this is so that you can later use it in SQL statements, print statements, and PL conditionals, by using the *{VARNAME} or *{:VARNAME} construct. The only difference between *{VARNAME} and *{:VARNAME} is that the former produces an error if VARNAME is not set, whereas the latter will expand to a zero-length string if VARNAME is not set. If you set a variable to an SQL statement (without the terminating ";") you can then use it as a PL alias like /VARNAME, as shown in this example. Defining and using a PL alias (PL variable) * qry = SELECT COUNT(*) FROM mytable \p The stored query is '*{qry}' /qry; /qry WHERE mass > 200; If you put variable definitions into the SQL file auto.sql in your home directory, those aliases/variables will always be available for interactive use. PL variables can be expanded within all commands other than : edit/history commands. * load VARNAME /file/path.txt Sets VARNAME to the content of the specified ASCII file. * prepare VARNAME Indicate that next command should be a SQL INSERT or UPDATE command containing one question mark. The value of VARNAME will be substuted for the ? variable. This does work for CLOB columns. * VARNAME _ When next SQL command is run, instead of displaying the rows, just store the very first column value to variable VARNAME. This works for CLOB columns too. It also works with Oracle XML type columns if you use column labels and the getclobval function. * VARNAME ~ Exactly the same as * VARNAME ~ except that the fetched results will be displayed in addition to setting the variable. * dump VARNAME /file/path.txt Store the value of VARNAME to the specified ASCII file.
                ? Variable You don't set the ? variable. It is just like the Bourne shell variable ? in that it is always automatically set to the first value of a result set (or the return value of other SQL commands). It works just like the * VARNAME ~ command described above, but it all happens automatically. You can, of course, dereference ? like any PL variable, but it does not list with the list and listvalues commands. You can see the value whenever you want by running \p *{?} Note that PL commands are used to upload and download column values to/from local ASCII files, but the corresponding actions for binary files use the special \b commands. This is because PL variables are used for ASCII values and you can store any number of column values in PL variables. This is not true for binary column values. The \b commands work with a single binary byte buffer. See the section below for information on using variables in other ways, and information on the other PL commands and features.
                Storing and retrieving binary files You can upload binary files such as photographs, audio files, or serialized Java objects into database columns. SqlTool keeps one binary buffer which you can load from files with the \bl command, or from a database query by doing a one-row query for any non-displayable type (including BLOB, OBJECT, and OTHER). In the latter case, the data returned for the first non-displayable column of the first result row will be stored into the binary buffer. Once you have data in the binary buffer, you can upload it to a database column (including BLOB, OBJECT, and OTHER type columns), or save it to a file. The former is accomplished by the special command \bp followed by a prepared SQL query containing one question mark place-holder to indicate where the data gets inserted. The latter is accomplished with the \bd command. You can also store the output from normal, displayable column into the binary buffer by using the special command \b. The very first column value from the first result row of the next SQL command will be stored to the binary byte buffer. Inserting binary data into database from a file \bl /tmp/favoritesong.mp3 \bp INSERT INTO musictbl (id, stream) VALUES(3112, ?); Downloading binary data from database to a file SELECT stream FROM musictbl WHERE id = 3112; \bd /tmp/favoritesong.mp3 You can also store and retrieve text column values to/from ASCII files, as documented in the section.
                Command History The SQL history shown by the \h command, and used by other commands, is truncated to 100 entries, since its utility comes from being able to quickly view the history list. You can change the history length by setting the system property sqltool.historyLength to an integer like java -Dsqltool.historyLength=100 -jar $HSQLDB_HOME/lib/hsqldb.jar urlid If there is any demand, I'll make the setting of this value more convenient. The SQL history list contains all executed commands other than Edit Buffer commands and comments, even if the command has a syntax error or fails upon execution. The reason for including bad commands is so that you can recall and fix them if you wish to. The same applies to the edit buffer. If you copy a command to the edit buffer by entering blank line, or if you edit the edit buffer, that edit buffer value will never make it into the command history until and if you execute it.
                Shell scripting and command-line piping You normally use non-interactive mode for input piping. You specify "-" as the SQL file name. See the subsection of the Non-Interactive chapter.
                Emulating Non-Interactive mode You can run SqlTool interactively, but have SqlTool behave exactly as if it were processing an SQL file (i.e., no command-line prompts, error-handling that defaults to fail-upon-error, etc.). Just specify "-" as the SQL file name in the command line. This is a good way to test what SqlTool will do when it encounters any specific command in an SQL file. See the subsection of the Non-Interactive chapter for an example.
                Non-Interactive Read the section if you have not already, because much of what is in this section builds upon that. You can skip all discussion about Command History and the edit buffer if you will not use those interactive features. If you're doing data updates, remember to issue a commit command or use the --autoCommit switch. As you'll see, SqlTool has many features that are very convenient for scripting. But what really makes it superior for automation tasks (as compared to SQL tools from other vendors) is the ability to reliably detect errors and to control JDBC transactions. SqlTool is designed so that you can reliably determine if errors occurred within SQL scripts themselves, and from the invoking environment (for example, from a perl, Bash, or Python script, or a simple cron tab invocation).
                Giving SQL on the Command Line If you just have a couple Commands to run, you can run them directly from the comand-line or from a shell script without an SQL file, like this. java -jar $HSQLDB_HOME/lib/hsqldb.jar --sql 'SQL statement;' urlid The --sql automatically implies --noinput, so if you want to execute the specified SQL before and in addition to an interactive session (or stdin piping), then you must also give the --stdinput switch. Since SqlTool transmits SQL statements to the database engine only when a line is terminated with ";", if you want feedback from multiple SQL statements in an --sql expression, you will need to use functionality of your OS shell to include linebreaks after the semicolons in the expression. With any Bourne-compatible shell, you can include linebreaks in the SQL statements like this. java -jar $HSQLDB_HOME/lib/hsqldb.jar --sql ' SQL statement number one; SQL statement number two; SQL statement three; ' urlid If you don't need feedback, just separate the SQL commands with semicolons and the entire expression will be chunked. The --sql switch is very useful for setting shell variables to the output of SQL Statements, like this. # A shell script USERCOUNT=`java -jar $HSQLDB_HOME/lib/hsqldb.jar --sql ' select count(*) from usertbl; ' urlid` || { # Handle the SqlTool error } echo "There are $USERCOUNT users registered in the database." [ "$USECOUNT" -gt 3 ] && { # If there are more than 3 users registered # Some conditional shell scripting
                SQL Files Just give paths to sql text file(s) on the command line after the urlid. Often, you will want to redirect output to a file, like java -jar $HSQLDB_HOME/lib/hsqldb.jar sql... > /tmp/log.sql 2>&1 (Skip the "2>&1" if you're on Windows). You can also execute SQL files from an interactive session with the "\i"' Special Command, but be aware that the default behavior in an interactive session is to continue upon errors. If the SQL file was written without any concern for error handling, then the file will continue to execute after errors occur. You could run \c false before \i filename, but then your SqlTool session will exit if an error is encountered in the SQL file. If you have an SQL file without error handling, and you want to abort that file when an error occurs, but not exit SqlTool, the easiest way to accomplish this is usually to add \c false to the top of the script. If you specify multiple SQL files on the command-line, the default behavior is to exit SqlTool immediately if any of the SQL files encounters an error. SQL files themselves have ultimate control over error handling. Regardless of what command-line options are set, or what commands you give interactively, if a SQL file gives error handling statements, they will take precedence. You can also use \i in SQL files. This results in nested SQL files. You can use the following SQL file, sample.sql, which resides in the sample directory of your HSQLDB distribution . It contains SQL as well as Special Commands making good use of most of the Special Commands documented below. &sample.sql-cdata; You can execute this SQL file with a Memory Only database with a command like java -jar $HSQLDB_HOME/lib/hsqldb.jar --sql ' create user tomcat password "x"; ' mem path/to/hsqldb/sample/sample.sql (The --sql "create...;" arguments create an account which the script uses). You should see error messages betwen the Continue-on-error...true and Continue-on-error...false. The script purposefully runs commands that might fail there. The reason the script does this is to perform database-independent conditional table removals. (The SQL clause IF EXISTS is more graceful and succinct, and should be used if you don't need to support databases which don't support IF EXISTS). If an error occurs when continue-on-error is false, the script would abort immedately.
                Piping and shell scripting You can of course, redirect output from SqlTool to a file or another program. java -jar $HSQLDB_HOME/lib/hsqldb.jar urlid file.sql > file.txt 2>&1 java -jar $HSQLDB_HOME/lib/hsqldb.jar urlid file.sql 2>&1 | someprogram... You can type commands in to SqlTool while being in non-interactive mode by supplying "-" as the file name. This is a good way to test how SqlTool will behave when processing your SQL files. java -jar $HSQLDB_HOME/lib/hsqldb.jar urlid - This is how you have SqlTool read its input from another program: Piping input into SqlTool echo "Some SQL commands with '$VARIABLES';" | java -jar $HSQLDB_HOME/lib/hsqldb.jar urlid - Make sure that you also read the section. The --sql switch is a great facility to use with shell scripts.
                Optimally Compatible SQL Files If you want your SQL scripts optimally compatible among other SQL tools, then don't use any Special or PL Commands. SqlTool has default behavior which I think is far superior to the other SQL tools, but you will have to disable these defaults in order to have optimally compatible behavior. These switches provide compatibilty at the cost of poor control and error detection. --continueOnErr The output will still contain error messages about everything that SqlTool doesn't like (malformatted commands, SQL command failures, empty SQL commands), but SqlTool will continue to run. Errors will not cause rollbacks (but that won't matter because of the following setting). --autoCommit You don't have to worry about accidental expansion of PL variables, since SqlTool will never expand PL variables if you don't set any variables on the command line, or give any "* " PL commands. (And you could not have "* " commands in a compatible SQL file).
                Comments SQL comments of the form /*...*/ must begin where a (SQL/Special/Edit-Buffer/PL) Command could begin, and they end with the very first "*/" (regardless of quotes, nesting, etc. You may have as many blank lines as you want inside of a comment. Valid comment example SELECT count(*) FROM atable; /* Lots of comments interspersed among several lines */ SELECT count(*) FROM btable; Notice that a command can start immediate after the comment ends. Invalid comment example SELECT count(*) FROM /* atable */ btable; This comment is invalid because you could not start another command at the comment location (because it is within an SQL Statement). You can try using /*...*/ in other locations, and -- style SQL comments, but SqlTool will not treat them as comments. If they occur within an SQL Statment, SqlTool will pass them to the database engine, and the DB engine will determine whether to parse them as comments.
                Special Commands and Edit Buffer Commands in SQL Files Don't use Edit Buffer / History Commands in your sql files, because they won't work. Edit Buffer / History Commands are for interactive use only. (But, see the section for an exception). You can, of course, use any SqlTool command at all interactively. I just wanted to group together the commands most useful to script-writers. \q [abort message] Be aware that the \q command will cause SqlTool to completely exit. If a script x.sql has a \q command in it, then it doesn't matter if the script is executed like java -jar .../hsqldb.jar urlid a.sql x.sql z.sql or if you use \i to read it in interactively, or if another SQL file uses \i to nest it. If \q is encountered, SqlTool will quit. See the section for commands to abort an SQL file (or even parts of an SQL file) without causing SqlTool to exit. \q takes an optional argument, which is an abort message. If you give an abort message, the message is displayed to the user and SqlTool will exit with a failure status. If you give no abort message, then SqlTool will exit quietly with successful status. As a result, \q means to make an immediate but graceful exit, whereas \q Message means to abort immediately. \p [text to print] Print the given string to stdout. Just give "\p" alone to print a blank line. \i /path/to/file.sql Include another SQL file at this location. You can use this to nest SQL files. For database installation scripts I often have a master SQL file which includes all of the other SQL files in the correct sequence. Be aware that the current continue-upon-error behavior will apply to included files until such point as the SQL file runs its own error handling commands. \o [file/path.txt] Tee output to the specified file (or stop doing so). See the section. \= A database-independent way to commit your SQL session. \a [true|false] This turns on and off SQL transaction autocommits. Auto-commit defaults to false, but you can change that behavior by using the --autoCommit command-line switch. \c [true|false] A "true" setting tells SqlTool to Continue when errors are encountered. The current transaction will not be rolled back upon SQL errors, so if \c is true, then run the ROLLCACK; command yourself if that's what you want to happen. The default for interactive use is to continue upon error, but the default for non-interactive use is to abort upon error. You can override this behavior by using the --continueOnErr or the --abortOnErr command-line switch. With database setup scripts, I usually find it convenient to set "true" before dropping tables (so that things will continue if the tables aren't there), then set it back to false so that real errors are caught. DROP TABLE tablename IF EXISTS; is a more elegant, but less portable, way to accomplish the same thing. It depends on what you want your SQL files to do, of course, but I usually want my SQL files to abort when an error is encountered, without necessarily killing the SqlTool session. If this is the behavior that you want, then put an explicit \c false at the top of your SQL file and turn on continue-upon-error only for sections where you really want to permit errors, or where you are using PL commands to handle errors manually. This will give the desired behavior whether your script is called by somebody interactively, from the SqlTool command-line, or included in another SQL file (i.e. nested). The default settings are usually best for people who don't want to put in any explicit \c or error handling code at all. If you run SQL files from the SqlTool command line, then any errors will cause SqlTool to roll back and abort immediately. If you run SqlTool interactively and invoke SQL files with \i commands, the scripts will continue to run upon errors (and will not roll back). This behavior was chosen because there are lots of SQL files out there that produce errors which can be ignored; but we don't want to ignore errors that a user won't see. I reiterate that any and all of this behavior can (and often should) be changed by Special Commands run in your interactive shell or in the SQL files. Only you know whether errors in your SQL files can safely be ignored.
                Automation SqlTool is ideal for mission-critical automation because, unlike other SQL tools, SqlTool returns a dependable exit status and gives you control over error handling and SQL transactions. Autocommit is off by default, so you can build a completely dependable solution by intelligently using \c commands (Continue upon Errors) and commit statements, and by verifying exit statuses. Using the SqlTool Procedural Language, you have ultimate control over program flow, and you can use variables for database input and output as well as for many other purposes. See the section.
                Getting Interactive Functionality with SQL Files Some script developers may run into cases where they want to run with sql files but they alwo want SqlTool's interactive behavior. For example, they may want to do command recall in the sql file, or they may want to log SqlTool's command-line prompts (which are not printed in non-interactive mode). In this case, do not give the sql file(s) as an argument to SqlTool, but pipe them in instead, like java -jar $HSQLDB_HOME/lib/hsqldb.jar urlid < filepath1.sql > /tmp/log.html 2>&1 or cat filepath1.sql... | java -jar $HSQLDB_HOME/lib/hsqldb.jar urlid > /tmp/log.html 2>&1
                Character Encoding SqlTool defaults to the US-ASCII character set (for reading). You can use another character set by setting the system property sqlfile.charset, like java -Dsqlfile.charset=UTF-8 -jar $HSQLDB_HOME/lib/hsqldb.jar urlid file.sql... You can also set this per urlid in the SqlTool configuration file. See the section about that.
                Generating Text or HTML Reports This section is about making a file containing the output of database queries. You can generate reports by using operating system facilities such as redirection, tee, and cutting and pasting. But it is much easier to use the "\o" and "\H" special commands. Writing query output to an external file By default, everthing will be done in plain text. If you want your report to be in HTML format, then give the special command \H. If you do so, you will probably want to use filenames with an suffix of ".html" or ".htm" instead of ".txt" in the next step. Run the command \o path/to/reportfile.txt. From this point on, output from your queries will be appended to the specified file. (I.e. another copy of the output is generated.) This way you can continue to monitor or use output as usual as the report is generated. When you want SqlTool to stop writing to the file, run \o (or just quit SqlTool if you have no other work to do). If you turned on HTML mode with \H before, you can run \H again to turn it back off, if you wish. It is not just the output of "SELECT" statements that will make it into the report file, but Kinds of output that get teed to \o files Output of SELECT statements. Output of all "\d" Special Commands. (I.e., "\dt", "\dv", etc., and "\d OBJECTNAME"). Output of "\p" Special Commands. You will want to use this to add titles, and perhaps spacing, for the output of individual queries. Other output will go to your screen or stdout, but will not make it into the report file. Be aware that no error messages will go into the report file. If SqlTool is run non-interactively (including if you give any SQL file(s) on the command line), SqlTool will abort with an error status if errors are encountered. The right way to handle errors is to check the SqlTool exit status. (The described error-handling behavior can be modified with SqlTool command-line switches and Special Commands). Remember that \o appends to the named file. If you want a new file, then use a new file name or remove the pre-existing target file ahead of time. So that I don't end up with a bunch of junk in my report file, I usually leave \o off while I perfect my SQL. With \o off, I perfect the SQL query until it produces on my screen exactly what I want saved to file. At this point I turn on \o and run ":;" to repeat the last SQL command. If I have several complex queries to run, I turn \o off and repeat until I'm finished. (Every time you turn \o on, it will append to the file, just like we need). Usually it doesn't come to mind that I need a wider screen until a query produces lines that are too long. In this case, stretch your window and repeat the last command with the ":;" Edit Buffer Command.
                SqlTool Procedural Language Aka PL Most importantly, run SqlTool interactively and give the "*?" command to see what PL commands are available to you. I've tried to design the language features to be intuitive. Readers experience with significant shell scripting in any language can probably learn everything they need to know by looking at (and running!) the sample script sample/pl.sql in your HSQLDB distribution and using the *? command from within an interactive SqlTool session as a reference. (By significant shell scripting, I mean to the extent of using variables, for loops, etc.). PL variables will only be expanded after you run a PL command (or set variable(s) from the command-line). We only want to turn on variable expansion if the user wants variable expansion. People who don't use PL don't have to worry about strings getting accidentally expanded. All other PL commands imply the "*" command, so you only need to use the "*" statement if your script uses PL variables and it is possible that no variables may be set before-hand (and no PL commands have been run previously). In this case, without "*", your script would silently use a literal value like "*{x}" instead of trying to expand it. With a preceding "*" command, PL will notice that the variable x has not been set and will generate an error. (If x had been set here will be no issue because setting a variable automatically turns on PL variable expansion). PL is also used to upload and download column values to/from local ASCII files, analogously to the special \b commands for binary files. This is explained above in the Interactive section above.
                Variables Use the * list command to list some or all variables; or * listvalues to also see the values. You can set variables using the * VARNAME = value command. This document explains elsewhere how you can set a values to the contents of files, and to the return value of SQL statements and fetches. You can also set variables using the --setvar command-line switch. I give a very brief but useful example of this below. Variables are always expanded in SQL, Special, and PL commands if they are written like *{VARNAME} (assuming that a PL command has been run previously). Your SQL scripts can give good feedback by echoing the value of variables with the "\p" special command. Use the construct *{:VARNAME} to expand the variable, but to expand to a zero-length string instead of fail if VARNAME is not set. A variable written like /VARNAME is expanded if it begins an SQL Statement. This usage is called PL Aliasing. See the section below. Variables are normally written like *VARNAME in logical expressions to prevent them from being evaluated too early. See below about logical expressions. You can't do math with expression variables, but you can get functionality like the traditional for (i = 0; i < x; i++) by appending to a variable and testing the string length, like * while (*i < ${x}) * i = *{i}. i will be a growing line of dots. Variable names must not contain white space, or the characters "}" or "=".
                PL Aliases PL Aliasing just means the use of a PL variable as the first thing in an SQL statement, with the shortcut notation /VARNAME. /VARNAME must be followed by whitespace or terminate the Statement, in order for SqlFile to tell where the variable name ends. Note that PL aliases are a very different thing from SQL aliases or HSQLDB aliases, which are features of databases, not SqlFile. If the value of a variable is an entire SQL command, you generally do not want to include the terminating ";" in the value. There is an example of this above. PL aliasing may only be used for SQL statements. You can define variables for everything in a Special or PL Command, except for the very first character ("\" or "*"). Therefore, you can use variables other than alias variables in Special and PL Commands. Here is a hyperbolically impractical example to show the extent to which PL variables can be used in Special commands even though you can not use them as PL aliases. sql> * qq = p Hello Butch sql> \*{qq} done now Hello Butch done now (Note that the \* here is not the special command "\*", but is the special command "\p" because "*{qq}" resolves to "p").
                Here is a short SQL file that gives the specified user write permissions on some application tables. Simple SQL file using PL /* grantwrite.sql Run SqlTool like this: java -jar path/to/hsqldb.jar -setvar USER=debbie grantwrite.sql */ /* Explicitly turn on PL variable expansion, in case no variables have been set yet. (Only the case if user did not set USER). */ * GRANT all ON book TO *{USER}; GRANT all ON category TO *{USER}; Note that this script will work for any (existing) user just by supplying a different user name on the command-line. I.e., no need to modify the tested and proven script. There is no need for a commit statement in this SQL file since no DML is done. If the script is accidentally run without setting the USER variable, SqlTool will give a very clear notificaton of that. The purpose of the plain "*" command is just so that the *{USER} variables will be expanded. (This would not be necessary if the USER variable, or any other variable, were set, but we don't want to depend upon that).
                Logical Expressions Logical expressions occur only inside of logical expression parentheses in PL statements. For example, if (*var1 > astring) and while (*checkvar). (The parentheses after "foreach" do not enclose a logical expression, they just enclose a list). There is a critical difference between *{VARNAME} and *VARNAME inside logical expressions. *{VARNAME} is expanded one time when the parser first encounters the logical expression. *VARNAME is re-expanded every time that the expression is evaluated. So, you would never want to code * while (*{X} < 5) because the statement will always be true or always be false. (I.e. the following block will loop infinitely or will never run). Don't use quotes or whitespace of any kind in *{VARNAME} variables in expressions. (They would expand and then the expression would most likely no longer be a valid expression as listed in the table below). Quotes and whitespace are fine in *VARNAME variables, but it is the entire value that will be used in evaluations, regardless of whether quotes match up, etc. I.e. quotes and whitespace are not special to the token evaluator. Logical Operators TOKEN The token may be a literal, a *{VARNAME} which is expanded early, or a *VARNAME which is expanded late. (You usually do not want to use *{VARNAME} in logical expressions). False if the token is not set, empty, or "0". True otherwise. TOKEN1 == TOKEN2 True if the two tokens are equivalent "strings". TOKEN1 <> TOKEN2 Ditto. TOKEN1 >< TOKEN2 Ditto. TOKEN1 > TOKEN2 True if the TOKEN1 string is longer than TOKEN2 or is the same length but is greater according to a string sort. TOKEN1 < TOKEN2 Similarly to TOKEN1 > TOKEN2. ! LOGICAL_EXPRESSION Logical negation of any of the expressions listed above. *VARNAMEs in logical expressions, where the VARNAME variable is not set, evaluate to an empty string. Therefore (*UNSETVAR = 0) would be false, even though (*UNSETVAR) by itself is false and (0) by itself is false. Another way of saying this is that *VARNAME in a logical expression is equivalent to *{:VARNAME} out of a logical expression. When developing scripts, you definitely use SqlTool interactively to verify that SqlTool evaluates logical expressions as you expect. Just run * if commands that print something (i.e. \p) if the test expression is true.
                Flow Control Flow control works by conditionally executing blocks of Commands according to conditions specified by logical expressions. The conditionally executed blocks are called PL Blocks. These PL Blocks always occur between a PL flow control statement (like * foreach, *while, * if) and a corresponding * end PL Command (like * end foreach). Be aware that the PL block reader is ignorant about SQL statements and comments when looking for the end of the block. It just looks for lines beginning with some specific PL commands. Therefore, if you put a comment line before a PL statement, or if a line of a multi-line SQL statement has a line beginning with a PL command, things may break. I am not saying that you shouldn't use PL commands or SQL commands inside of PL blocks-- you definitely should! I'm saying that in PL blocks you should not have lines inside of SQL statments or comments which could be mistaken for PL commands. (Especially, "commenting out" PL end statements will not work if you leave * end at the beginning of the line). (This limitation will very likely be removed in a future version of SqlTool). The values of control variables for foreach and while PL blocks will change as expected. There are * break and * continue, which work as any shell scripter would expect them to. The * break command can also be used to quit the current SQL file without triggering any error processing. (I.e. processing will continue with the next line in the including SQL file or interactive session, or with the next SQL file if you supplied multiple on the command-line).
                Below is an example SQL File that shows how to use most PL features. If you have a question about how to use a particular PL feature, check this example before asking for help. This file resides in the sample directory with the name pl.sql . Definitely give it a run, like java -jar $HSQLDB_HOME/lib/hsqldb.jar mem $HSQLDB_HOME/pl.jar SQL File showing use of most PL features &pl.sql-cdata;
                Chunking We hereby call the ability to transmit multiple SQL commands to the database in one transmission chunking. Unless you are in Raw mode, SqlTool only transmits commands to the database engine when it reads in a ";" at the end of a line of an SQL command. Therefore, you normally want to end each and every SQL command with ";" at the end of a line. This is because the database can only send one status reply to each JDBC transmission. So, while you could run SELECT * FROM t1; SELECT * FROM t2; SqlTool can only display the results from the last query. This is a limitation of the client/server nature of JDBC, and applies to any JDBC client. There are, however, situations where you don't need immediate feedback from every SQL command. For example, Single-line chunking example INSERT INTO t1 VALUES(0); SELECT * FROM t1; It's useful because the output of the second SQL command will tell you whether the first SQL command succeeded. So, you won't miss the status output from the first command.
                Why? The first general reason to chunk SQL commands is performance. For standalone databases, the most common performance bottleneck is network latency. Chunking SQL commands can dramatically reduce network traffic. The second general reason to chunk SQL commands is if your database requires you to send multiple commands in one transmission. This is often the case when you need to tell the database the SQL or PL/SQL commands that comprise a stored procedure, function, trigger, etc.
                How? The most simple way is enter as many SQL commands as you want, but just do not end a line with ";" until you want the chunk to transmit. Multi-line chunking example INSERT INTO t1 VALUES (1) ; INSERT INTO t1 VALUES (2) ; SELECT * FROM t1; If you list your command history with \s, you will see that all 3 SQL commands in 3 lines are in one SqlTool command. You can recall this SqlTool command from history to re-execute all three SQL commands. The other method is by using . Go to the section to see how. You can enter any text at all, exactly how you want it to be sent to the database engine. Therefore, in addition to chunking SQL commands, you can give commands for non-SQL extensions to the database. For example, you could enter JavaScript code to be used in a stored procedure.
                Raw Mode You begin raw mode by issuing the Special Command "\.". You can then enter as much text in any format you want. When you are finished, enter a line consisting of only ".;" to store the input to the edit buffer and send it to the database server for execution. This paragraph applies only to interactive usage. Interactive users may may end the raw input with ":." instead of ".;". This will just save the input to the edit buffer so that you can edit it and send it to the database manually. You can look at the edit buffer with the ":b" Buffer Command. You would normally use the command ":;" to send the buffer to the database after you are satisfied with it. You'll notice that your prompt will be the continuation prompt between entering "\." and terminating the raw input with ".;" or ":.". Interactive Raw Mode example sql> \. Enter RAW SQL. No \, :, * commands. End with a line containing only ".;" to send to database, or ":." to store to edit buffer for editing or saving. ----------------------------------------------------------- raw> line one; +> line two; +> line three; +> :. Raw SQL chunk moved into buffer. Run ":;" to execute the chunk. sql> :; Executing command from buffer: line one; line two; line three; SQL Error at 'stdin' line 13: "line one; line two; line three;" Unexpected token: LINE in statement [line] sql> The error message "Unexpected token: LINE in statement [line]" comes from the database engine, not SqlTool. All three lines were transmitted to the database engine. Edit Buffer Commands are not available when running SqlTool non-interactively.
                PL/SQL PL/SQL is not the same as PL. PL is the procedural language of SqlFile and is independent of your back-end database. PL commands always begin with *. PL/SQL is processed on the server side and you can only use it of your database supports it. You can not intermix PL and PL/SQL (except for setting a PL variable to the output of PL/SQL execution), because when you enter PL/SQL to SqlTool that input is not processed by SqlFile. Use to send PL/SQL code blocks to the database engine. You do not need to enter the "\." command to enter raw mode. Just begin a new SqlTool command line with "DECLARE" or "BEGIN", and SqlTool will automatically put you into raw mode. See the section for details. The following sample SQL file resides at sample/plsql.sql in your HSQLDB distribution . This script will only work if your database engine supports standard PL/SQL, if you have permission to create the table "T1" in the default schema, and if that object does not already exist. PL/SQL Example &plsql.sql-cdata; Note that, inside of raw mode, you can use any kind of formatting you want: Whatever you enter-- blank lines, comments, everything-- will be transmitted to the database engine.
                Using hsqltool.jar and hsqldbutil.jar This section is for those users who want to use SqlTool but without the overhead of hsqldb.jar (or who want to use a new SqlTool build with an older HSQLDB distribution). If you do not need to directly use JDBC URLs like jdbc:hsqldb:mem: + something, jdbc:hsqldb:file: + something, or jdbc:hsqldb:res: + something, then you can use hsqltool.jar in place of the much larger hsqldb.jar file. hsqltool.jar will work for all JDBC databases other than HSQLDB Memory-only and In-process databases (the latter are fine if you access them via a HSQLB Server or WebServer). You will have to supply the JDBC driver for non-HSQLDB URLs, of course. hsqltool.jar includes the HSQLDB JDBC driver. If you do not need to connect to HSQLDB databases at all, then hsqldbutil.jar is what you want. hsqldbutil.jar contains everything you need to run SqlTool and DatabaseManagerSwing against non-HSQLDB databases... well, besides the JDBC drivers for the target databases. The HSQLDB distribution doesn't "come with" pre-built hsqltool.jar and hsqldbutil.jar files. You need to "build" them, but that is very easy to do. These instructions assume that you are capable of running an Ant build. See the chapter if you need more details than what you see here. Download and extract a current HSQLDB distribution. If you don't want to use the source code, documentation, etc., you can use a temporary directory and remove it afterwards. Cd to the build directory under the root directory where you extracted the distribution to. Run ant hsqldbutil or ant hsqltool according to the criteria above. (If your goal is to use this jar with an older HSQLDB distribution, then you definitely need to build hsqlbutil.jar). If you're going to clean up afterwards, copy the jar that you built out of lib to a safe location first. If you are using the HSQLDB JDBC driver (i.e., you're connecting up to a URL like jdbc:hsqldb:hsql + something or jdbc:hsqldb:http + something), you invoke SqlTool exactly as with hsqldb.jar except you use the file path to your new jar file instead of the path to hsqldb.jar. If you are using a non-HSQLDB JDBC driver, you must set your CLASSPATH to include this new jar file and your JDBC driver, then run SqlTool like java org.hsqldb.util.SqlTool ... You can specify your JDBC driver class either with the --driver switch to SqlTool, or in your RC file stanza (the last method is usually more convenient).
                Delimiter-Separated-Value Imports and Exports This feature is independent of HSQLDB , a server-side feature of HSQLDB. It makes no difference to SqlTool whether the source or target table of your export/import is a memory, cache, or text table. Indeed, like all features of SqlTool, it works fine with other JDBC databases. It works great, for example to migrate data from a table of one type to a table of another type, or to another schema, or to another database instance, or to another database system. This feature is what most business people call "CSV", but these files are more accurately called Delimiter Separated Value files because the delimiter is usually not a comma, and, more importantly, we purposefully choose an effective delimiter instead of the CSV method of using a delimiter which works in some cases and then use quotes and back-slashes to escape occurrence of the delimiter in the actual data. Just by choosing a delimiter which never needs escaping, we eliminate the whole mess, and the data in our files always looks just like the corresponding data in the database. To make this CSV / Delimiter-separated-value dintinction clear, I use the suffix ".dsv" for my data files. This leads me to stipulate the abbreviation DSV for the Delimiter Separated Value feature of HSQLDB. Use the \x command to eXport a table to a DSV file, and the \m command to iMport a DSV file into a pre-existing table. The row and column delimiters may be any String, not just a single character. And just as the delimiter capability is more general than traditional CSV delimiters, the export function is also more general than just a table data exporter. Besides the trivial generalization that you may specify a view or other virtual table name in place of a table name, you can alternatively export the output of any query which produces normal text output. A benefit to this approach is that it allows you to export only some columns of a table, and to specify a WHERE clause to narrow down the rows to be exported (or perform any other SQL transformation, mapping, join, etc.). One specific use for this would be to exclude columns of binary data (which can be exported by other means, such as a PL loop to store binary values to files with the \bd command). Note that the import command will not create a new table. This is because of the impossibility of guessing appropriate types and constraints based only on column names and a data sampling (which is all that a DSV-importer has access to). Therefore, if you wish to populate a new table, create the table before running the import. The import file does not need to have data for all columns of a table. The only required columns are those required by database constraints (non-null, indexes, keys, etc.) One specific reason to omit columns is if you want values of some columns to be created automatically by column DEFAULT settings, triggers, HSQLDB identity sequences, etc. Another reason would be to skip binary columns.
                Simple DSV exports and imports using default settings Even if you need to change delimiters, table names, or file names from the defaults, I suggest that you run one export and import with default settings as a practice run. A memory-only HSQLDB instance is ideal for test runs like this. This command exports the table icf.projects to the file projects.dsv in the current directory (where you invoked SqlTool from). By default, the output file name will be the specified source table name plus the extension .dsv. DSV Export Example SET SCHEMA icf; \x projects We could also have run \x icf.projects (which would have created a file named icf.projects.dsv) instead of changing the session schema. In this example we have chosen to make the export file name independent of the schema to facilitate importing it into a different schema. Take a look at the output file. Notice that the first line consists of column names, not data. This line is present because it will be needed if the file is to used for a DSV import. Notice the following characterstics about the export data. The column delimiter is the pipe character "|". The record delimiter is the default line delimiter character(s) for your operating system. The string used to represent database NULLs is [null]. See the next section for how to change these from their default values. This command imports the data from the file projects.dsv in the current directory (where you invoked SqlTool from) into the table newschema.projects. By default, the output table name will be the input filename after removing optional leading directory and trailing final extension. DSV Import Example SET SCHEMA newschema; \m projects.dsv If the DSV file was named with the target schema, you would have skipped the SET SCHEMA command, like \m newschema.projects.dsv.
                Specifying queries and options For a hands on example of a DSM import which generates an import report and uses some other options, change to directory HSQLDB/sample and play with the working script dsv-sample.sql . You can execute it like java -jar ../lib/hsqldb.jar mem dsv-sample.sql (assuming that you are using the supplied sqltool.rc file or have have urlid mem set up. The header line in the DSV file is required at this time. (If there is user demand, it can be made optional for exporting, but it will remain required for importing). Your export will fail if the column or record delimiter, or the null representation value occurs in the data being exported. You change these values by setting the PL variables *DSV_COL_DELIM, *DSV_ROW_DELIM, *DSV_NULL_REP. Notice that the asterisk is part of the variable names, to indicate that these variables are used by SqlTool internally. When specifying delimiters, you can use the escape seqpences \n, \r, \f, \t, \\, and decimal, octal or hex specifications like \20, \020, \0x20. For example, to change the column delimiter to the tab character, you would give the command * *DSV_COL_DELIM = \t For imports, you must always specify the source DSV file path. If you want to export to a different file than one in the current directory named according to the source table, set the PL variable *DSV_TARGET_FILE, like * *DSV_TARGET_FILE = /tmp/dtbl.dsv For exports, you must always specify the source table name or query. If you want to import to a table other than that derived from the input DSV file name, set the PL variable *DSV_TARGET_TABLE. The table name may contain a schema name prefix. You don't need to import all of the columns in a data file. To designate the fields to be skipped, iether set the PL PL variable *DSV_SKIP_COLUMNS, or replace the column names in the header line to "-" (hyphen). The value of *DSV_SKIP_COLUMNS is case-insensitive, and multiple column names are separated with white space and/or commas. You can specify a query instead of a tablename with the \x command in order to filter or transform data from a table or view, or to export the output of a join, etc. You must set the PL variable *DSV_TARGET_FILE, as explained above (since there is no table name from which to automatically map a file name). DSV Export of an Arbitrary SELECT Statement * *DSV_TARGET_FILE = outfile.txt \x SELECT entrydate, 2 * aval "Double aval", modtime FROM bs.dtbl Note that I specified the column label alias "Double aval" so that the label for that column in the DSV file header will not be blank. By default, imports will abort as soon as a error is encountered during parsing the file or inserting data. If you invoke SqlTool with a SQL script on the command line, the failure will cause SqlTool to roll back and exit. If run interactively, you can decide whether to commit or roll back the rows that inserted before the failure. You can modify this behavior with the \a and \c settings. If you set either a reject dsv file or a reject report file, then failures during imports will be reported but will not cause the import to abort. When run in this way, SqlTool will give you a report at the end about how many records were skipped, rejected, and successfully inserted. The reject dsv file is just a dsv file with exact copies of the dsv records that failed to insert. The reject report file is a HTML report which lists, for every rejected record, why that record was rejected. To allow for user-friendly entry of headers, we require that tables for DSV import/exports use standard column names. I.e., no column names that require quoting. The DSV import and export parsers are very smart and user-friendly. The data types of columns are checked so that the parser can make safe assumptions about white space and blank entries in the data. If a column is a JDBC Boolean type, for example, then we know that a field value of " True " obviously means "True", and that a field value of "" obviously means null. Since we require vanilla style column names, we allow white space anywhere in the header column. We allow blank lines anywhere (where "lines" are delimited by *DSV_ROW_DELIM). By default, commented lines are ignored, and the comment character can be changed from its default value. Run the command "\x?" or "\m?" to see the several system PL variables which you can set to adjust reject file behavior, commenting behavior, and other DSV features. You can also define some settings right in the DSV file, and you can even specify multiple header lines in a single DSV file. I use this last feature to import data from one data set into multple tables that are joined. Since I don't have any more time to dedicate to explaining all of these features, I'll give you some examples from working DSV files and let you take it from there. Sample DSV headerswitch settings # RCS keyword was here. headerswitch{ itemdef:name|-|-|hardness|breakdc|- simpleitemdef:itemdef_name|maxvalue|weight|-|-|maxhp } I'll just note that the prefixes for the header rows must be of format target-table-name + :. You can use * for target-table-name here, for the obvious purpose. DSV targettable setting targettable=t This last example is from the SqlTool unit test file dsv-trimming.dsv. These special commands must be at the top of the file (before any normal data or header lines). There is also the *DSV_CONST_COLS setting, which you can use to automatically write static, constant values to the specified columns of all inserted rows.
                Unit Testing SqlTool The SqlTool unit tests reside at testrun/sqltool in the HSQLDB source code repository. Just run the runtests.bash script from that directory to execute all of the tests. Read the file README.txt to find out all about it, including everything you'd need to know to test your own scripts or to add more unit test scripts for SqlTool.

Among these, the TestSelf class performs the tests that are based on scripts. To run the tests, you should compile the hsqldbtest.jar target with Ant. For TestSelf, a batch file is provided in the testrun/hsqldb directory, together with a set of TestSelf*.txt files. To start the application in Windows, change to the directory and type: runtest TestSelf In Unix / Linux, type: ./runTest.sh TestSelf The new version of TestSelf runs multiple SQL test files to test different SQL operations of the database. All files in the working directory with names matching TestSelf*.txt are processed in alphabetical order. You can add your own scripts to test different series of SQL queries. The format of the TestSelf*.txt file is simple text, with some indentation and prefixes in the form of Java-style comments. The prefixes indicate what the expected result should be. Comment lines must start with -- and are ignored Lines starting with spaces are the continuation of the previous line SQL statements with no prefix are simply executed. The remaining items in this list exemplify use of the available command line-prefixes. The /*s*/ option stands for silent. It is used for executing quries regardless of results. Used for preparation of tests, not for actual tests. /*s*/ Any SQL statement - errors are ignored The /*c<rows>*/ option is for SELECT queries and asserts the number of rows in the result matches the given count. /*c<rows>*/ SQL statement returning count of <rows> The /*u*/ option is for queries that return an update count, such as DELETE and UPDATE. It asserts the update count matches. /*u<count>*/ SQL statement returning an update count equal to <count> The /*e*/ option asserts that the given query results in an erros. It is mainly used for testing the error detection capabilities of the engine. It can also be used with syntactically valid queries to assert a certain state in the database. For example a CREATE TABLE can be used to assert the table of the same name already exists. /*e*/ SQL statement that should produce an error when executing The /*r....*/ option asserts the SELECT query returns a single row containing the given set of field values. /*r<string1>,<string2>*/ SQL statement returning a single row ResultSet equal to the specified value The extended /*r...*/ option asserts the SELECT query returns the given rows containing the given set of field values. /*r <string1>,<string2> <string1>,<string2> <string1>,<string2> */ SQL statement returning a multiple row ResultSet equal to the specified values (note that the result set lines are indented). All the options are lowercase letters. During development, an uppercase can be used for a given test to exclude a test from the test run. The utility will just report the test blocks that have been excluded without running them. Once the code has been developed, the option can be turned into lowercase to perform the actual test. See the TestSelf*.txt files in the /testrun/hsqldb/ directory for actual examples. hsqldb-1.8.0.10.orig/docsrc/guide/dbmanager.xml0000644000175000017500000003201710462225505017637 0ustar renerene Database Manager Fred Toussi HSQLDB Development Group ft@cluedup.com Blaine Simpson HSQLDB Development Group ft@cluedup.com $Revision: 1.13 $ $Date: 2006/07/27 21:08:21 $ Hsqldb Database Manager
                Brief Introduction The Database Manager tool is a simple GUI database query tool with a tree display of the tables. Both AWT and SWING versions of the tool are available and work almost identically. The AWT version class name is org.hsqldb.util.DatabaseManager; the SWING version, org.hsqldb.util.DatabaseManagerSwing. The AWT version of the database manager can be deployed as an applet in a browser. A demo HTML file with an embedded Database Manager is included in the /demo directory. When the Database Manager is started, a dialogue allows you to enter the JDBC driver, URL, user and password for the new connection. A drop-down box, Type, offers preset values for JDBC driver and URL for most popular database engines, including HSQLDB. Once you have selected an item from this drop-down box, you should edit the URL to specify the details of the database or any additional properties to pass. You should also enter the username and password before clicking on the OK button. The connection dialogue allows you to save the settings for the connection you are about to make. You can then access the connection in future sessions. To save a connection setting, enter a name in the Setting Name box before clicking on the OK button. Next time the connection dialogue is displayed, the drop-down box labeled Recent will include the name for all the saved connection settings. When you select a name, the individual settings are displayed in the appropriate boxes. The small Clr button next to the drop-down box allows you to clear all the saved settings. If you want to modify an existing setting, first select it from the drop-down box then modify any of the text boxes before making the connection. The modified values will be saved. Most menu items have context-sensitive tool tip help text which will appear if you hold the mouse cursor still over the desired menu item. (Assuming that you don't turn Tooltips off under the Help menu. The DatabaseManagers do work with HSQLDB servers serving TLS-encrypted JDBC data. See the chapter and the section of this Guide. If you are using DatabaseManagerSwing with Oracle, you will want to make sure that Show row counts and Show row counts are both off before connecting to the database. You may also want to turn off Auto tree-update, as described in the next section.
                Auto tree-update By default, the object tree in the left panel is refreshed when you execute DDL which may update those objects. If you are on a slow network or performance-challenged PC, use the view / Auto-refresh tree menu item to turn it off. You will then need to use the viewRefresh tree menu item every time that you want to refresh the tree. Auto-refresh tree does not automatically show all updates to database objects, it only refreshes when you submit DDL which may update database objects. (This behavior is a compromise between utility and performance).
                Automatic Connection You can use command-line switches to supply connection information. If you use these switch(es), then the connection dialog window will be skipped and a JDBC connection will be established immediately. Assuming that the hsqldb.jar (or an alternative jar) are in your CLASSPATH, this command will list the available command-line options. java org.hsqldb.util.DatabaseManagerSwing --help It's convenient to skip the connection dialog window if you always work with the same database account. Use of the --password switch is not secure. Everything typed on command-lines is generally available to other users on the computer. The problem is compounded if you use a network connection to obtain your command line. The RC File section explains how you can set up automatic connections without supplying a password on the command line.
                RC File You can skip the connection dialog window securely by putting the connection information into an RC file and then using the --urlid switch to DatabaseManager or DatabaseManagerSwing. This strategy is great for adding launch menu items and/or launch icons to your desktop. You can set up one icon for each of the database accounts which you regularly use. The default location for the RC file is dbmanager.rc in your home directory. The section explains how to put the connection information into this text file. If you also run , then you can share the RC file with SqlTool by using a sym-link (if your operating system supports sym links), or by using the --rcfile switch for either SqlTool or DatabaseManagerSwing. Use your operating system facilities to prevent others from reading your RC file, since it contains passwords. To set up launch items/icons, first experiment on your command line to find exactly what command works. For example, java -cp /path/to/hsqldb.jar org.hsqldb.util.DatabaseManagerSwing --urlid mem Then, use your window manager to add an item that runs this command.
                Using the current DatabaseManagers with an older HSQLDB distribution. This procedure will allow users of a legacy version of HSQLDB to use all of the new features of the DatabaseManagers. You will also get the new version of the SqlTool! This procedure works for distros going back to 1.7.3.3 at least, probably much farther. These instructions assume that you are capable of running an Ant build. See the chapter. Download and extract a current HSQLDB distribution. If you don't want to use the source code, documentation, etc., you can use a temporary directory and remove it afterwards. Cd to the build directory under the root directory where you extracted the distribution to. Run ant hsqldbutil. If you're going to wipe out the build directory, copy hsqldbutil.jar to a safe location first. For now on, whenver you are going to run DatabaseManager*, make sure that you have this hsqldbutil.jar as the first item in your CLASSPATH. Here's a UNIX example where somebody wants to use the new DatabaseManagerSwing with their older HSQLDB database, as well as with Postgresql and a local application. CLASSPATH=/path/to/hsqldbutil.jar:/home/bob/myapp/classes:/usr/local/lib/pg.jdbc3.jar export CLASSPATH java org.hsqldb.util.DatabaseManagerSwing --urlid urlid
                DatabaseManagerSwing as an Applet DatabaseManagerSwing is also an applet. You can use it in HTML, JSPs, etc. Be aware that in Applet mode, actions to load or save local files will be disabled, and attempts to access any server other than the HTML-serving-host will be fail. Since the Applet can not store or load locally saved preferences, the only way to have persistent preference settings is by using Applet parameters. DatabaseManagerSwing Applet Parameters jdbcUrl URL of a data source to auto-connect to. String value. jdbcDriver URL of a data source to auto-connect to. String value.

Permission is granted to distribute this document without any alteration under the terms of the HSQLDB license. Additional permission is granted to the HSQLDB Development Group to distribute this document with or without alterations under the terms of the HSQLDB license. Text Table support for HSQLDB was originally developed by Bob Preston independently from the Project. Subsequently Bob joined the Project and incorporated this feature into version 1.7.0, with a number of enhancements, especially the use of conventional SQL commands for specifying the files used for Text Tables. In a nutshell, Text Tables are CSV or other delimited files treated as SQL tables. Any ordinary CSV or other delimited file can be used. The full range of SQL queries can be performed on these files, including SELECT, INSERT, UPDATE and DELETE. Indexes and unique constraints can be set up, and foreign key constraints can be used to enforce referential integrity between Text Tables themselves or with conventional tables. HSQLDB with Text Table support is the only comprehensive solution that employs the power of SQL and the universal reach of JDBC to handle data stored in text files and will have wide-ranging use way beyond the currently established Java realm of HSQLDB. Goals of the Implementation We aimed to finalise the DDL for Text Tables so that future releases of HSQLDB use the same DDL scripts. We aimed to support Text Tables as GLOBAL TEMPORARY or GLOBAL BASE tables in the SQL domain.
                The Implementation
                Definition of Tables Text Tables are defined similarly to conventional tables with the added TEXT keyword: CREATE TEXT TABLE <tablename> (<column definition> [<constraint definition>]) In addition, a SET command specifies the file and the separator character that the Text table uses: SET TABLE <tablename> SOURCE <quoted_filename_and_options> [DESC] Text Tables cannot be created in memory-only databases (databases that have no script file).
                Scope and Reassignment A Text table without a file assigned to it is READ ONLY and EMPTY. A Temporary Text table has the scope and the lifetime of the SQL session (a JDBC Connection). Reassigning a Text Table definition to a new file has implications in the following areas: The user is required to be an administrator. Existing transactions are committed at this point. Constraints, including foreign keys referencing this table, are kept intact. It is the responsibility of the administrator to ensure their integrity. From version 1.7.2 the new source file is scanned and indexes are built when it is assigned to the table. At this point any violation of NOT NULL, UNIQUE or PRIMARY KEY constrainst are caught and the assignment is aborted. However, foreign key constraints are not checked at the time of assignment or reassignment of the source file.
                Null Values in Columns of Text Tables This has changed since 1.7.2 to support both null values and empty strings. Empty fields are treated as NULL. These are fields where there is nothing or just spaces between the separators. Quoted empty strings are treated as empty strings.
                Configuration The default field separator is a comma (,). A different field separator can be specified within the SET TABLE SOURCE statement. For example, to change the field separator for the table mytable to a vertical bar, place the following in the SET TABLE SOURCE statement, for example: SET TABLE mytable SOURCE "myfile;fs=|" Since HSQLDB treats CHAR's, VARCHARs, and LONGVARCHARs the same, the ability to assign different separators to the latter two is provided. When a different separator is assigned to a VARCHAR or LONGVARCHAR field, it will terminate any CSV field of that type. For example, if the first field is CHAR, and the second field LONGVARCHAR, and the separator fs has been defined as the pipe (|) and vs as the period (.) then the data in the CSV file for a row will look like: First field data|Second field data.Third field data The following example shows how to change the default separator to the pipe (|), VARCHAR separator to the period (.) and the LONGVARCHAR separator to the tilde (~). Place the following within the SET TABLE SOURCE statement, for example: SET TABLE mytable SOURCE "myfile;fs=|;vs=.;lvs=~" HSQLDB also recognises the following special indicators for separators: special indicators for separators \semi semicolon \quote qoute \space space character \apos apostrophe \n newline - Used as an end anchor (like $ in regular expressions) \r carriage return \t tab \\ backslash \u#### a Unicode character specified in hexadecimal Furthermore, HSQLDB provides csv file support with three additional boolean options: ignore_first, quoted and all_quoted. The ignore_first option (default false) tells HSQLDB to ignore the first line in a file. This option is used when the first line of the file contains column headings. The all_quoted option (default false) tells the program that it should use quotes around all character fields when writing to the source file. The quoted option (default true) uses quotes only when necessary to distinguish a field that contains the separator character. It can be set to false to prevent the use of quoting altogether and treat quote characters as normal characters. These options may be specified within the SET TABLE SOURCE statement: SET TABLE mytable SOURCE "myfile;ignore_first=true;all_quoted=true" When the default options all_quoted= false and quoted=true are in force, fields that are written to a line of the csv file will be quoted only if they contain the separator or the quote character. The quote character is doubled when used inside a string. When all_quoted=false and quoted=false the quote character is not doubled. With this option, it is not possible to insert any string containing the separator into the table, as it would become impossible to distinguish from a separator. While reading an existing data source file, the program treats each individual field separately. It determines that a field is quoted only if the first character is the quote character. It interprets the rest of the field on this basis. The character encoding for the source file is ASCII by default. To support UNICODE or source files preprared with different encodings this can be changed to UTF-8 or any other encoding. The default is encoding=ASCII and the option encoding=UTF-8 or other supported encodings can be used. Finally, HSQLDB provides the ability to read a text file from the bottom up and making them READ ONLY, by placing the keyword "DESC" at the end of the SET TABLE SOURCE statement: SET TABLE mytable SOURCE "myfile" DESC This feature provides functionality similar to the Unix tail command, by re-reading the file each time a select is executed. Using this feature sets the table to read-only mode. Afterwards, it will no longer be possible to change the read-only status with SET TABLE <tablename> READONLY TRUE. Text table source files are cached in memory. The maximum number of rows of data that are in memory at any time is controlled by the textdb.cache_scale property. The default value for textdb.cache_scale is 10 and can be changed by setting the property in the .properties file for the database. The number of rows in memory is calculated as 3*(2**scale), which translates to 3072 rows for the default textdb.cache_scale setting (10). The property can also be set for individual text tables: SET TABLE mytable SOURCE "myfile;ignore_first=true;all_quoted=true;cache_scale=12"
                Disconnecting Text Tables The following describes behaviour present in 1.8.0.8 and later. Text tables may be disconnected from their underlying data source, i.e. the text file. You can explicitly disconnect a text table from its file by issuing the following statement: SET TABLE mytable SOURCE OFF Subsequently, mytable will be empty and read-only. However, the data source description will be preserved, and the table can be re-connected to it with SET TABLE mytable SOURCE ON When a database is opened, if the source file for an existing text table is missing the table remains disconnected from its data source, but the source sescription is preserved. This allows the missing source file to be added to the directory and the table re-connected to it with the above command.
                Text File Issues Text File Issues File locations are restricted to below the directory that contains the database, unless the textdb.allow_full_path property is set true in the database properties file. Blank lines are allowed anywhere in the text file, and are ignored. The file location for a text table created with SELECT <select list> INTO TEXT <tablename> FROM is the directory that contains the database and the file name is based on the table name. The table name is converted into the file name by replacing all the non-alphanumeric characters with the underscore character, conversion into lowercase, and adding the ".csv" suffix. It is possible to define a primay key or identity column for text tables. When a table source file is used with the ignore_first=true option, the first, ignored line is replaced with a blank line after a SHUTDOWN COMPACT. An existing table source file may include CHARACTER fields that do not begin with the quote character but contain instances of the quote character. These fields are read as literal strings. Alternatively, if any field begins with the quote character, then it is interpreted as a quoted string that should end with the quote character and any instances of the quote character within the string is doubled. When any field containing the quote character or the separator is written out to the source file by the program, the field is enclosed in quote character and any instance of the quote character inside the field is doubled.

                Importing a Text Table file in to a Traditional (non-Text Table) Table Importing from a Text Table file The directory src/org/hsqldb/sample in your HSQLDB distibution contains a file named load_binding_lu.sql. This is a working SQL file which imports a pipe-delimited text file from the database's file directory into an existing normal table. You can edit a copy of this file and use it directly with SqlTool, or you can use the SQL therein as a model (using any SQL client at all).

SSL) BlaineSimpson &blaineaddr; HSQLDB Development Group $Revision: 1.17 $ $Date: 2006/07/27 21:08:21 $ Hsqldb TLS SSL JSSE Security The instructions in this document are liable to change at any time. In particular, we will be changing the method to supply the server-side certificate password.
                Requirements Hsqldb TLS Support Requirements Sun Java 2.x and up. (This is probably possible with IBM's Java, but I don't think anybody has attempted to run HSQLDB with TLS under IBM's Java, and I'm sure that nobody in the HSQLDB Development Group has documented how to set up the environment). If Java 2.x or 3.x, then you will need need to install JSSE. Your server and/or client will start up much slower than that of Java 4.x users. Client-side users will not be able to use the https: JDBC protocol (because the https protocol handler is not implemented in 2.x/3.x Java JSSE; if there is demand, we could work around this). A JKS keystore containing a private key, in order to run a server. If you are running the server side, then you'll need to run a HSQLDB Server or WebServer. It doesn't matter if the underlying database instances are new, and it doesn't matter if you are making a new Server configuration or encrypting an existing Server configuration. (You can turn encryption on and off at will). You need a HSQLDB jar file that was built with JSSE present. If you got your HSQLDB 1.7.2 distribution from us, you are all set, because we build with Java 1.4 (which contains JSSE). If you build your own jar file with Java 1.3, make sure to install JSSE first.
                Encrypting your JDBC connection At this time, only 1-way, server-cert encryption is tested.
                Client-Side Just use one of the following protocol prefixes. Hsqldb TLS URL Prefixes jdbc:hsqldb:hsqls:// jdbc:hsqldb:https:// At this time, the latter will only work for clients running with Java 1.4. If the server you wish to connect to is using a certificate approved by your default trust keystores, then there is nothing else to do. If not, then you need to tell Java to "trust" the server cert. (It's a slight over-simplification to say that if the server certificate was purchased, then you are all set; if somebody "signed their own" certificate by self-signing or using a private ca certificate, then you need to set up trust). First, you need to obtain the cert (only the "public" part of it). Since this cert is passed to all clients, you could obtain it by writing a java client that dumps it to file, or perhaps by using openssl s_client. Since in most cases, if you want to trust a non-commercial cert, you probably have access to the server keystore, I'll show an example of how to get what you need from the server-side JKS keystore. You may already have an X509 cert for your server. If you have a server keystore, then you can generate a X509 cert like this. Exporting certificate from the server's keystore keytool -export -keystore server.store -alias existing_alias -file server.cer In this example, server.cer is the X509 certificate that you need for the next step. Now, you need to add this cert to one of the system trust keystores or to a keystore of your own. See the Customizing Stores section in JSSERefGuide.html to see where your system trust keystores are. You can put private keystores anywhere you want to. The following command will add the cert to an existing keystore, or create a new keystore if client.store doesn't exist. Adding a certificate to the client keystore keytool -import -trustcacerts -keystore trust.store -alias new_alias -file server.cer If you are making a new keystore, you probably want to start with a copy of your system default keystore which you can find somewhere under your JAVA_HOME directory (typically jre/lib/security/cacerts for a JDK, but I forget exactly where it is for a JRE). Unless your OS can't stop other people from writing to your files, you probably do not want to set a password on the trust keystore. If you added the cert to a system trust store, then you are finished. Otherwise you will need to specify your custom trust keystore to your client program. The generic way to set the trust keystore is to set the sytem property javax.net.ssl.trustStore every time that you run your client program. For example Specifying your own trust store to a JDBC client java -Djavax.net.ssl.trustStore=/home/blaine/trust.store -jar /path/to/hsqldb.jar dest-urlid This example runs the program SqlTool. SqlTool has built-in TLS support, however, so, for SqlTool you can set truststore on a per-urlid basis in the SqlTool configuration file. N.b. The hostname in your database URL must match the Common Name of the server's certificate exactly. That means that if a site certificate is admc.com, you can not use jdbc:hsqldb:hsqls://localhost or jdbc:hsqldb:hsqls://www.admc.com:1100 to connect to it. If you want more details on anything, see JSSERefGuide.html on Sun's site, or in the subdirectory docs/guide/security/jsse of your Java SE docs.
                Server-Side Get yourself a JKS keystore containing a private key. Then set the system property javax.net.ssl.keyStore to the path to that file, and javax.net.ssl.keyStorePassword to the password of the keystore (and to the private key-- they have to be the same). Running an Hsqldb server with TLS encryption java -Djavax.net.ssl.keyStorePassword=secret \ -Djavax.net.ssl.keyStore=/usr/hsqldb/db/db3/server.store \ -cp /path/to/hsqldb.jar org.hsqldb.Server (This is a single command that I have broken into 2 lines using my shell's \ line-continuation feature. In this example, I'm using a server.properties file so that I don't need to give arguments to specify database instances or the server endpoint). Specifying a password on the command-line is definitely not secure. It's really only appropriate when untrusted users do not have any access to your computer. If there is any user demand, we will have a more secure way to supply the password before long.
                JSSE If you are running Java 4.x, then you are all set. Java 1.x users, you are on your own (Sun does not provide a JSSE that will work with 1.x). Java 2.x and 3.x users continue... Go to . If you agree to the terms and meet the requirements, download the domestic or global JSSE software. All you need from the software distro is the three jar files. If you have a JDK installation, then move the 3 jar files into the directory $JAVA_HOME/jre/lib/ext. If you have a JRE installation, then move the 3 jar files into the directory $JAVA_HOME/lib/ext. Pretty painless.
                Making a Private-key Keystore There are two main ways to do this. Either you can use a certificate signed by a certificate authority, or you can make your own. One thing that you need to know in both cases is, the Common Name of the cert has to be the exact hostname that JDBC clients will use in their database URL.
                CA-Signed Cert I'm not going to tell you how to get a CA-signed SSL certificate. That is well documented at many other places. Assuming that you have a standard pem-style private key certificate, here's how you can use openssl and the program DERImport to get it into a JKS keystore. Because I have spent a lot of time on this document already, I am just giving you an example. Getting a pem-style private key into a JKS keystore openssl pkcs8 -topk8 -outform DER -in Xpvk.pem -inform PEM -out Xpvk.pk8 -nocrypt openssl x509 -in Xcert.pem -out Xcert.der -outform DER java DERImport new.keystore NEWALIAS Xpvk.pk8 Xcert.der Make sure to set the password of the key exactly the same as the password for the keystore! You need the program DERImport.class of course. Do some internet searches to find DERImport.java or DERImport.class and download it. If DERImport has become difficult to obtain, I can write a program to do the same thing-- just let me know.
                Non-CA-Signed Cert Run man keytool or see the Creating a Keystore section of JSSERefGuide.html.
                Automatic Server or WebServer startup on UNIX If you are on UNIX and want to automatically start and stop a Server or WebServer running with encryption, follow the instructions in the chapter, and remember to make the init script configuration file readable only to root and to set the variables TLS_PASSWORD and TLS_KEYSTORE. If you are using a private server certificate, make sure to also set the trust store filepath as shown in the sample init script configuration file. The cautionary warning above still applies. The password will be visible to any minimally competent local UNIX user who wants to see it.

                Brief Introduction Transfer Tool is a GUI program for transferring SQL schema and data from one JDBC source to another. Source and destination can be different database engines or different databases on the same server. Transfer Tool works in two different modes. Direct transfer maintains a connection to both source and destination and performs the transfer. Dump and Restore mode is invoked once to transfer the data from the source to a text file (Dump), then again to transfer the data from the text file to the destination (Restore). With Dump and Restore, it is possible to make any changes to database object definitions and data prior to restoring it to the target. Dump and Restore modes can be set via the command line with -d (--dump) or -r (--restore) options. Alternatively the Transfer Tool can be started with any of the three modes from the Database Manager's Tools menu. The connection dialogue allows you to save the settings for the connection you are about to make. You can then access the connection in future sessions. These settings are shared with those from the Database Manager tool. See the appendix on Database Manager for details of the connection dialogue box. In version 1.8.0 Transfer Tool is no longer part of the hsqldb.jar. You can build the hsqldbutil.jar using the Ant command of the same name, to build a jar that includes Transfer Tool and the Database Manager. When collecting meta-data, Transfer Tool performs SELECT * FROM <table> queries on all the tables in the source database. This may take a long time with some database engines. When the source database is HSQLDB, this means memory should be available for the result sets returned from the queries. Therefore, the memory allocation of the java process in which Transfer Tool is executed may have to be high.

                Purpose From 1.8.0, the supplied hsqldb.jar file is built with Java 1.5. If you want to run the engine under JDK1.3 or earlier, you should rebuild the jar with Ant.
                Building with Ant, from the Apache Jakarta Project Building with Ant Ant (Another Neat Tool) is used for building hsqldb. The version currently used to test the build script is 1.6.1 but versions since 1.5.1 should also be compatible.
                Obtaining Ant Ant is a part of the Jakarta/Apache Project. Home of the Apache Ant project The Installing Ant page of the Ant Manual . Follow the directions for your platform.
                Building Hsqldb with Ant Once you have unpacked the zip package for hsqldb, under the /hsqldb folder, in /build there is a build.xml file that builds the hsqldb.jar with Ant (Ant must be already installed). To use it, change to /build then type: ant -projecthelp This displays the available ant targets, which you can supply as command line arguments to ant. These include hsqldb to make the hsqldb.jar explainjars Lists all targets which build jar files, with an explanation of the purposes of the different jars. clean to clean up the /classes directory that is created cleanall to remove the old jar as well javadoc to build javadoc hsqldbmain to build a smaller jar for HSQLDB that does not contain utilities hsqljdbc to build an extremely small jar containing only the client-side JDBC driver (does not support direct connection to HSQLDB URLs of the form jdbc:hsldb:mem:*, jdbc:hsqldb:file:*, nor jdbc:hsqldb:res:*). hsqldbmin to build a small jar that supports HSQLDB URLs of the form jdbc:hsqldb:mem:*, jdbc:hsqld:file*, jdbc:hsqldb:res:*; but not network URLs like jdbc:hsql* or jdbc:http*. hsqldbtest to build a larger jar for hsqldb that contains tests ... Many more targets are available. Run ant -projecthelp and ant explainjars. HSQLDB can be built in any combination of three JRE (Java Runtime Environment) versions and many jar file sizes. The smallest jar size(hsqljdbc.jar) contains only the HSQLDB JDBC Driver client. The default size (hsqldb.jar) also contains server mode support and the utilities. The largest size (hsqldbtest.jar)includes some test classes as well. Before building the hsqldbtest.jar package, you should download the junit jar from and put it in the /lib directory, alongside servlet.jar, which is included in the .zip package. Just run ant explainjars for a concise list of all available jar files. If you want your code built for debugging, as opposed to high performance, make a file named build.properties in your build directory with the contents build.debug: true The resulting Java binaries will be larger and slower, but exception stack traces will contain source code line numbers, which can be extremely useful for debugging. The preferred method of rebuilding the jar is with Ant. After installing Ant on your system use the following command from the /build directory: ant explainjars The command displays a list of different options for building different sizes of the HSQLDB Jar. The default is built using: Buiding the standard Hsqldb jar file with Ant ant hsqldb The Ant method always builds a jar with the JDK that is used by Ant and specified in its JAVA_HOME environment variable. Building with JDK 1.4.x or 1.5.x will result in a jar that is not backward compatible. From version 1.7.2, use of JDK 1.1.x is not recommended for building the JAR, even for running under JDK 1.1.x -- use JDK 1.3.1 for compatibility with 1.1.x. This is done in the following way. JDK 1.3.1 should be used as the JAVA_HOME for ant. You then issue the following commands. The first command will make the sources compatible with JDK 1.3, the second command modifies the sources further so that the compiled result can run under jdk 1.1 as well. The third command builds the jar. ant switchtojdk12 ant switchtojava1target ant hsqldb
                Building with DOS Batch Files UNIX users must use Ant to build hsqldb. For DOS/Windows users, a set of MSDOS batch files is provided as an example. These files produce only the default jar size. The path and classpath variables for the JDK should of course be set before running any of the batch files. These files are not currently maintained and will probably need some additions and changes to work correctly. Please see the build.xml file for up-to-date file If you are compiling for JDK's other than 1.4.x, you should use the appropriate switchToJDK11.bat or switchToJDK12.bat to adapt the source files to the target JDK before running the appropriate buildJDK11.bat or buildJDK12.bat JDK and JRE versions.
                Hsqldb CodeSwitcher CodeSwitcher is a tool to manage different version of Java source code. It allows to compile HSQLDB for different JDKs. It is something like a precompiler in C but it works directly on the source code and does not create intermediate output or extra files. CodeSwitcher is used internally in HSQLDB build scripts. You do not have to use it separately to compile HSQLDB. CodeSwitcher reads the source code of a file, removes comments where appropriate and comments out the blocks that are not used for a particular version of the file. This operation is done for all files of a defined directory, and all subdirectories. Example source code before CodeSwitcher is run ... //#ifdef JAVA2 properties.store(out,"hsqldb database"); //#else /* properties.save(out,"hsqldb database"); */ //#endif ... The next step is to run CodeSwitcher. CodeSwitcher command line invocation java org.hsqldb.util.CodeSwitcher . -JAVA2 The '.' means the program works on the current directory (all subdirectories are processed recursively). -JAVA2 means the code labelled with JAVA2 must be switched off. Source code after CodeSwitcher processing ... //#ifdef JAVA2 /* pProperties.store(out,"hsqldb database"); */ //#else pProperties.save(out,"hsqldb database"); //#endif ... For detailed information on the command line options run java org.hsqldb.util.CodeSwitcher. Usage examples can be found in the switchtojdk1*.bat files in the /build directory.
                Building documentation To build the User Guide in HTML format, you must have the Docbook stylesheets installed locally. The Docbook stylesheets are available on the Internet. On Linux, just install the docbook-xsl-stylesheets rpm. Then add an entry to build.properties in your build directory with contents like docbook.xsl.home: /usr/share/sgml/docbook/docbook-xsl-stylesheets Where you specify your local path to the base directory of your Docbook stylesheet installation. Build like Building HTML User Guides ant docbooks-html ant docbooks-chunk To build the User Guide in PDF format, you must also have the Java FOP system installed locally. FOP is available for free download on the Internet. Add an entry to build.properties in your build directory with contents like fop.home /usr/local/fop-0.20.5 Where you specify your local path to the base directory of your FOP installation. Building User Guides in all formats ant docbook Don't pay too much attention to error messages by FOP, because they are really warnings, but do check the output. If there are problems with the PDF output, try using a newer version of FOP. By default, your docs will fail to build if you do not have Internet connectivity. This is because our primary Docbook source file references the Docbook DTDs via Internet URL. You can build without Internet connectivity by installing the Docbook DTDs and editing our primary Docbook source file. Docbook is available on the Internet. On Linux, just install the docbook-dtds or docbook rpm. Then make one edit to the file docsrc/guide/guide.xml in your HSQLDB distribution. Change the line containing "http://www.oasis-open.org/docbook/xml/4.2CR1/docbookx.dtd" [ to "file:///usr/share/xml/docbook/schema/dtd/4.2/docbookx.dtd" [ where the second filepath is the path to the docbookx.dtd file within your Docbook installation.

                The Standalone and Client/Server modes will in most cases use files to store all data to disk in a persistent and safe way. This document describes the meaning of the files, the states and the procedures followed by the engine to recover the data. A database named 'test' is used in this description. The database files will be as follows.
                Database Files test.properties Contains the entry 'modified'. If the entry 'modified' is set to 'yes' then the database is either running or was not closed correctly (because the close algorithm sets 'modified' to 'no' at the end). test.script This file contains the SQL statements that makes up the database up to the last checkpoint - it is in synch with test.backup. test.data This file contains the (binary) data records for CACHED tables only. test.backup This is compressed file that contains the complete backup of the old test.data file at the time of last checkpoint. test.log This file contains the extra SQL statements that have modified the database since the last checkpoint (something like the 'Redo-log' or 'Transaction-log', but just text). In the above list, a checkpoint results from both a CHECKPOINT command and a SHUTDOWN command.
                States
                Database is closed correctly
                State after using the command <literal>SHUTDOWN</literal> The test.data file is fully updated. The test.backup contains the compressed test.data file. The test.script contains the information in the database, excluding data for CACHED and TEXT tables. The test.properties contains the entry 'modified' set to 'no'. There is no test.log file.
                Database is closed correctly with SHUTDOWN SCRIPT
                State after using the command <literal>SHUTDOWN SCRIPT</literal> The test.data file does not exist; all CACHED table data is in the test.script file The test.backup does not exist. The test.script contains the information in the database, including data for CACHED and TEXT tables. The test.properties contains the entry 'modified' set to 'no'. There is no test.log file.
                Database is aborted
                This may happen by sudden power off, Ctrl+C in Windows, but may be simulated using the command SHUTDOWN IMMEDIATELY. Aborted Database state The test.properties still containes 'modified=yes'. The test.script contains a snapshot of the database at the last checkpoint and is OK. The test.data file may be corrupt because the cache in memory was not written out completely. The test.backup file contains a snapshot of test.data that corresponds to test.script. The test.log file contain all information to re-do all changes since the snanapshot. As a result of abnormal termination, this file may be partially corrupt.
                Procedures The database engine performs the following procedures internally in different circumstances.
                Clean Shutdown Clean Hsqldb database shutdown The test.data file is written completely (all the modified cached table rows are witten out) and closed. The test.backup.new is created (containing the compressed test.data file) The file test.script.new is created using the information in the database (and thus shrinks because no UPDATE and DELETE statements; only INSERT). The entry 'modified' in the properties file is set to 'yes-new-files' The file test.script is deleted The file test.script.new is renamed to test.script The file test.backup is deleted The file test.backup.new is renamed to test.backup The entry 'modified' in the properties file is set to 'no' The file test.log is deleted
                Startup Database is opened Check if the database files are in use (by checking a special test.lck file). See if the test.properties file exists, otherwise create it. If the test.properties did not exist, then this is a new database. Create the empty test.log to append new commands. If it is an existing database, check in the test.properties file if 'modified=yes'. This would mean last time it was not closed correctly, and thus the test.data file may be corrupted or incomplete. In this case the 'REPAIR' algorithm is executed (see below), before the database is opened normally. Otherwise, if in the test.properties file 'modified=yes-new-files', then the (old) test.backup and test.script files are deleted and the new test.script.new file is renamed to test.script. Open the test.script file and execute the commands. Create the empty test.log to append new commands.
                Repair The current test.data file is corrupt, but with the old test.data (from the test.backup file and test.script) and the current test.log, the database is made up-to-date. The database engine takes these steps: Database Repair Restore the old test.data file from the backup (uncompress the test.backup and overwrite test.data). Execute all commands in the test.script file. Execute all commands in the test.log file. If due to corruption, an exception is thrown, the rest of the lines of command in the test.log file are ignored. Close the database correctly (including a backup).

                Introduction The HSQLDB jar package is located in the /lib directory and contains several components and programs. Different commands are used to run each program. Components of the Hsqldb jar package HSQLDB RDBMS HSQLDB JDBC Driver Database Manager (Swing and AWT versions) Query Tool (AWT) Sql Tool (command line) The HSQLDB RDBMS and JDBC Driver provide the core functionality. The rest are general-purpose database tools that can be used with any database engine that has a JDBC driver.
                Running Tools All tools can be run in the standard way for archived Java classes. In the following example the AWT version of the Database Manager, the hsqldb.jar is located in the directory ../lib relative to the current directory. java -cp ../lib/hsqldb.jar org.hsqldb.util.DatabaseManager If hsqldb.jar is in the current directory, the command would change to: java -cp hsqldb.jar org.hsqldb.util.DatabaseManager Main classes for the Hsqldb tools org.hsqldb.util.DatabaseManager org.hsqldb.util.DatabaseManagerSwing org.hsqldb.util.Transfer org.hsqldb.util.QueryTool org.hsqldb.util.SqlTool Some tools, such as the Database Manager or SQL Tool, can use command line arguments or entirely rely on them. You can add the command line argument -? to get a list of available arguments for these tools. Database Manager features a graphical user interface and can be explored interactively.
                Running Hsqldb HSQLDB can be run in a number of different ways. In general these are divided into Server Modes and In-Process Mode (also called Standalone Mode). A different sub-program from the jar is used to run HSQLDB in each mode. Each HSQLDB database consists of between 2 to 5 files, all named the same but with different extensions, located in the same directory. For example, the database named "test" consists of the following files: test.properties test.script test.log test.data test.backup The properties files contains general settings about the database. The script file contains the definition of tables and other database objects, plus the data for non-cached tables. The log file contains recent changes to the database. The data file contains the data for cached tables and the backup file is a zipped backup of the last known consistent state of the data file. All these files are essential and should never be deleted. If the database has no cached tables, the test.data and test.backup files will not be present. In addition to those files, HSQLDB database may link to any formatted text files, such as CSV lists, anywhere on the disk. While the "test" database is operational, a test.log file is used to write the changes made to data. This file is removed at a normal SHUTDOWN. Otherwise (with abnormal shutdown) this file is used at the next startup to redo the changes. A test.lck file is also used to record the fact that the database is open. This is deleted at a normal SHUTDOWN. In some circumstances, a test.data.old is created and deleted afterwards. When the engine closes the database at a shutdown, it creates temporary files with the extension .new which it then renames to those listed above.
                Server Modes Server modes provide the maximum accessibility. The database engine runs in a JVM and listens for connections from programs on the same computer or other computers on the network. Several different programs can connect to the server and retrieve or update information. Applications programs (clients) connect to the server using the HSQLDB JDBC driver. In most server modes, the server can serve up to 10 databases that are specified at the time of running the server. Server modes can use preset properties or command line arguments as detailed in the chapter. There are three server modes, based on the protocol used for communications between the client and server.
                Hsqldb Server This is the preferred way of running a database server and the fastest one. A proprietary communications protocol is used for this mode. A command similar to those used for running tools and described above is used for running the server. The following example of the command for starting the server starts the server with one (default) database with files named "mydb.*". java -cp ../lib/hsqldb.jar org.hsqldb.Server -database.0 file:mydb -dbname.0 xdb The command line argument -? can be used to get a list of available arguments.
                Hsqldb Web Server This mode is used when access to the computer hosting the database server is restricted to the HTTP protocol. The only reason for using the Web Server mode is restrictions imposed by firewalls on the client or server machines and it should not be used where there are no such restrictions. The HSQLDB Web Server is a special web server that allows JDBC clients to connect via HTTP. From 1.7.2 this mode also supports transactions. To run a web server, replace the main class for the server in the example command line above with the following: org.hsqldb.WebServer The command line argument -? can be used to get a list of available arguments.
                Hsqldb Servlet This uses the same protocol as the Web Server. It is used when a separate servlet engine (or application server) such as Tomcat or Resin provides access to the database. The Servlet Mode cannot be started independently from the servlet engine. The Servlet class, in the HSQLDB jar, should be installed on the application server to provide the connection. The database is specified using an application server property. Refer to the source file org.hsqldb.Servlet.java to see the details. Both Web Server and Servlet modes can only be accessed using the JDBC driver at the client end. They do not provide a web front end to the database. The Servlet mode can serve only a single database. Please note that you do not normally use this mode if you are using the database engine in an application server.
                Connecting to a Database running as a Server Once an HSQLDB server is running, client programs can connect to it using the HSQLDB JDBC Driver contained in hsqldb.jar. Full information on how to connect to a server is provided in the Java Documentation for jdbcConnection (located in the /doc/src directory of HSQLDB distribution. A common example is connection to the default port (9001) used for the hsql protocol on the same machine: Java code to connect to the local Server above try { Class.forName("org.hsqldb.jdbcDriver" ); } catch (Exception e) { System.out.println("ERROR: failed to load HSQLDB JDBC driver."); e.printStackTrace(); return; } Connection c = DriverManager.getConnection("jdbc:hsqldb:hsql://localhost/xdb", "sa", ""); In some circumstances, you may have to use the following line to get the driver. Class.forName("org.hsqldb.jdbcDriver").newInstance(); Note in the above connection URL, there is no mention of the database file, as this was specified when running the server. Instead, the value defined for dbname.0 is used. Also, see the chapter for the connection URL when there is more than one database per server instance.
                Security Considerations When HSQLDB is run as a server, network access should be adequately protected. Source IP addresses may be restricted by use of TCP filtering or firewall programs, or standalone firewalls. If the traffic will cross an unprotected network (such as the Internet), the stream should be encrypted (for example by VPN, ssh tunneling, or using the SSL enabled HSQLS and HTTPS variants of the server and web server modes). Only secure passwords should be used-- most importantly, the password for the default system user should be changed from the default empty string. If you are purposefully providing data to the public, then the wide-open public network connection should be used exclusively to access the public data via read-only accounts. (I.e., neither secure data nor privileged accounts should use this connection). These considerations also apply to HSQLDB servers run with the HTTP protocol.
                In-Process (Standalone) Mode This mode runs the database engine as part of your application program in the same Java Virtual Machine. For most applications this mode can be faster, as the data is not converted and sent over the network. The main drawback is that it is not possible by default to connect to the database from outside your application. As a result you cannot check the contents of the database with external tools such as Database Manager while your application is running. In 1.8.0, you can run a server instance in a thread from the same virtual machine as your application and provide external access to your in-process database. The recommended way of using the in-process mode in an application is to use an HSQLDB Server instance for the database while developing the application and then switch to In-Process mode for deployment. An In-Process Mode database is started from JDBC, with the database file path specified in the connection URL. For example, if the database name is testdb and its files are located in the same directory as where the command to run your application was issued, the following code is used for the connection: Connection c = DriverManager.getConnection("jdbc:hsqldb:file:testdb", "sa", ""); The database file path format can be specified using forward slashes in Windows hosts as well as Linux hosts. So relative paths or paths that refer to the same directory on the same drive can be identical. For example if your database path in Linux is /opt/db/testdb and you create an identical directory structure on the C: drive of a Windows host, you can use the same URL in both Windows and Linux: Connection c = DriverManager.getConnection("jdbc:hsqldb:file:/opt/db/testdb", "sa", ""); When using relative paths, these paths will be taken relative to the directory in which the shell command to start the Java Virtual Machine was executed. Refer to Javadoc for jdbcConnection for more details.
                Memory-Only Databases It is possible to run HSQLDB in a way that the database is not persistent and exists entirely in random access memory. As no information is written to disk, this mode should be used only for internal processing of application data, in applets or certain special applications. This mode is specified by the mem: protocol. Connection c = DriverManager.getConnection("jdbc:hsqldb:mem:aname", "sa", ""); You can also run a memory-only server instance by specifying the same URL in the server.properties. This usage is not common and is limited to special applications where the database server is used only for exchanging information between clients, or for non-persistent data.
                General
                Closing the Database All databases running in different modes can be closed with the SHUTDOWN command, issued as an SQL query. From version 1.7.2, in-process databases are no longer closed when the last connection to the database is explicitly closed via JDBC, a SHUTDOWN is required. In 1.8.0, a connection property, shutdown=true, can be specified on the first connection to the database (the connection that opens the database) to force a shutdown when the last connection closes. When SHUTDOWN is issued, all active transactions are rolled back. A special form of closing the database is via the SHUTDOWN COMPACT command. This command rewrites the .data file that contains the information stored in CACHED tables and compacts it to size. This command should be issued periodically, especially when lots of inserts, updates or deletes have been performed on the cached tables. Changes to the structure of the database, such as dropping or modifying populated CACHED tables or indexes also create large amounts of unused file space that can be reclaimed using this command.
                Using Multiple Databases in One JVM In the above examples each server serves only one database and only one in-memory database can be created. However, from version 1.7.2, HSQLDB can serve several databases in multiple server modes and allow simultaneous access to multiple in-process and memory-only databases. These capabilities are covered in the chapter.
                Creating a New Database When a server instance is started, or when a connection is made to an in-process database, a new, empty database is created if no database exists at the given path. This feature has a side effect that can confuse new users. If a mistake is made in specifying the path for connecting to an existing database, a connection is nevertheless established to a new database. For troubleshooting purposes, you can specify a connection property ifexists=true to allow connection to an existing database only and avoid creating a new database. In this case, if the database does not exist, the getConnection() method will throw an exception.
                Using the Database Engine Once a connection is established to a database in any mode, JDBC methods are used to interact with the database. The Javadoc for jdbcConnection , jdbcDriver , jdbcDatabaseMetadata , jdbcResultSet , jdbcStatement , and jdbcPreparedStatement list all the supported JDBC methods together with information that is specific to HSQLDB. JDBC methods are broadly divided into: connection related methods, metadata methods and database access methods. The database access methods use SQL commands to perform actions on the database and return the results either as a Java primitive type or as an instance of the java.sql.ResultSet class. You can use Database Manager or other Java database access tools to explore your database and update it with SQL commands. These programs use JDBC internally to submit your commands to the database engine and to display the results in a human readable format. The SQL dialect used in HSQLDB is as close to the SQL92 and SQL200n standards as it has been possible to achieve so far in a small-footprint database engine. The full list of SQL commands is in the chapter.
                Different Types of Tables HSQLDB supports TEMP tables and three types of persistent tables. TEMP tables are not written to disk and last only for the lifetime of the Connection object. The contents of each TEMP table is visible only from the Connection that was used to populate it; other concurrent connections to the database will have access to their own copies of the table. Since 1.8.0 the definition of TEMP tables conforms to the GLOBAL TEMPORARY type in the SQL standard. The definition of the table persists but each new connections sees its own copy of the table, which is empty at the beginning. When the connection commits, the contents of the table are cleared by default. If the table definition statements includes ON COMMIT PRESERVE ROWS, then the contents are kept when a commit takes place. The three types of persistent tables are MEMORY tables, CACHED tables and TEXT tables. Memory tables are the default type when the CREATE TABLE command is used. Their data is held entirely in memory but any change to their structure or contents is written to the <dbname>.script file. The script file is read the next time the database is opened, and the MEMORY tables are recreated with all their contents. So unlike TEMP table, the default, MEMORY tables are persistent. CACHED tables are created with the CREATE CACHED TABLE command. Only part of their data or indexes is held in memory, allowing large tables that would otherwise take up to several hundred megabytes of memory. Another advantage of cached tables is that the database engine takes less time to start up when a cached table is used for large amounts of data. The disadvantage of cached tables is a reduction in speed. Do not use cached tables if your data set is relatively small. In an application with some small tables and some large ones, it is better to use the default, MEMORY mode for the small tables. TEXT tables are supported since version 1.7.0 and use a CSV (Comma Separated Value) or other delimited text file as the source of their data. You can specify an existing CSV file, such as a dump from another database or program, as the source of a TEXT table. Alternatively, you can specify an empty file to be filled with data by the database engine. TEXT tables are efficient in memory usage as they cache only part of the text data and all of the indexes. The Text table data source can always be reassigned to a different file if necessary. Two commands are needed to set up a TEXT table as detailed in the chapter. With memory-only databases (see above), both MEMORY table and CACHED table declarations are treated as declarations for non-persistent memory tables. TEXT table declarations are not allowed in this mode.
                Constraints and Indexes HSQLDB supports PRIMARY KEY, NOT NULL, UNIQUE, CHECK and FOREIGN KEY constraints. In addition, it supports UNIQUE or ordinary indexes. This support is fairly comprehensive and covers multi-column constraints and indexes, plus cascading updates and deletes for foreign keys. HSQLDB creates indexes internally to support PRIMARY KEY, UNIQUE and FOREIGN KEY constraints: a unique index is created for each PRIMARY KEY or UNIQUE constraint; an ordinary index is created for each FOREIGN KEY constraint. Because of this, you should not create duplicate user-defined indexes on the same column sets covered by these constraints. This would result in unnecessary memory and speed overheads. See the discussion in the chapter for more information. Indexes are crucial for adequate query speed. When queries joining multiple tables are used, there must be an index on each joined column of each table. When range or equality conditions are used e.g. SELECT ... WHERE acol >10 AND bcol = 0, an indexe is required on the acol column used in the condition. Indexes have no effect on ORDER BY clauses or some LIKE conditions. As a rule of thumb, HSQLDB is capable of internal processing of queries at over 100,000 rows per second. Any query that runs into several seconds should be checked and indexes should be added to the relevant columns of the tables if necessary.
                SQL Support The SQL syntax supported by HSQLDB is essentially that specified by the SQL Standard (92 and 200n). Not all the features of the Standard are supported and there are some proprietary extensions. In 1.8.0 the behaviour of the engine is far more compliant with the Standards than with older versions. The main changes are correct treatment of NULL column values in joins, in UNIQUE constraints and in query conditions correct processing of selects with JOIN and LEFT OUTER JOIN correct processing of aggregate functions contained in expressions or containing expression arguments The supported commands are listed in the chapter. For a well written basic guide to SQL with examples you can consult PostgreSQL: Introduction and Concepts by Bruce Momjian, which is available on the web. Most of the SQL coverage in the book applies also to HSQLDB. There are some differences in keywords supported by one and not the other engine (OUTER, OID's, etc.) or used differently (IDENTITY/SERIAL, TRIGGER, SEQUENCE, etc.).
                JDBC Support Since 1.7.2, support for JDBC2 has been significantly extended and some features of JDBC3 are also supported. The relevant classes are thoroughly documented. See the JavaDoc for org.hsqldb.jdbcXXXX classes.

                SQL Commands
                ALTER INDEX<footnote id="posthyper"> <para>These features were added by HSQL Development Group since April 2001</para> </footnote> ALTER INDEX <indexname> RENAME TO <newname>; Index names can be changed so long as they do not conflict with other user-defined or sytem-defined names.
                ALTER SEQUENCE<footnoteref linkend="posthyper" /> ALTER SEQUENCE <sequencename> RESTART WITH <value>; Resets the next value to be returned from the sequence.
                ALTER SCHEMA<footnoteref linkend="posthyper" /> ALTER SCHEMA <schemaname> RENAME TO <newname>; Renames the schema as specified. All objects of the schema will hereafter be accessible only with the new schema name. Requires Administrative privileges.
                ALTER TABLE<footnoteref linkend="posthyper" /> ALTER TABLE <tablename> ADD [COLUMN] <columnname> Datatype [(columnSize[,precision])] [{DEFAULT <defaultValue> | GENERATED BY DEFAULT AS IDENTITY (START WITH <n>[, INCREMENT BY <m>])}] | [[NOT] NULL] [IDENTITY] [PRIMARY KEY] [BEFORE <existingcolumn>]; Adds the column to the end of the column list. The optional BEFORE <existingcolumn> can be used to specify the name of an existing column so that the new column is inserted in a position just before the <existingcolumn>. It accepts a as in a CREATE TABLE command. If NOT NULL is specified and the table is not empty, then a default value must be specified. In all other respects, this command is the equivalent of a column definition statement in a CREATE TABLE statement. If an SQL view includes a SELECT * FROM <tablename> in its select statement, the new column is added to the view. This is a non-standard feature which is likely to change in the future. ALTER TABLE <tablename> DROP [COLUMN] <columnname>; Drops the column from the table. Will drop any single-column primary key or unique constraint on the column as well. The command will not work if there is any multiple key constraint on the column or the column is referenced in a check constraint or a foreign key. It will also fail if an SQL view includes the column. ALTER TABLE <tablename> ALTER COLUMN <columnname> RENAME TO <newname> Changes a column name. ALTER TABLE <tablename> ALTER COLUMN <columnname> SET DEFAULT <defaultvalue>}; Adds the specified default value to the column. Use NULL to remove a default. ALTER TABLE <tablename> ALTER COLUMN <columnname> SET [NOT] NULL Sets or removes a NOT NULL constraint for the column. ALTER TABLE <tablename> ALTER COLUMN <columnDefinition>; This form of ALTER TABLE ALTER COLUMN accepts a as in a CREATE TABLE command, with the following restrictions. Restrictions The column must be already be a PK column to accept an IDENTITY definition. If the column is already an IDENTITY column and there is no IDENTITY definition, the existing IDENTITY attribute is removed. The default expression will be that of the new definition, meaning an existing default can be dropped by ommission, or a new default added. The NOT NULL attribute will be that of the new definition (similar to previous item). Depending on the type of change, the table may have to be empty for the command to work. It always works when the type of change is possible in general and the individual existing values can all be converted. ALTER TABLE <tablename> ALTER COLUMN <columnname> RESTART WITH <new sequence value> This form is used exclusively for IDENTITY columns and changes the next automatic value for the identity sequence. ALTER TABLE <tablename> ADD [CONSTRAINT <constraintname>] CHECK (<search condition>); Adds a check constraint to the table. In the current version, a check constraint can reference only the row being inserted or updated. ALTER TABLE <tablename> ADD [CONSTRAINT <constraintname>] UNIQUE (<column list>); Adds a unique constraint to the table. This will not work if there is already a unique constraint covering exactly the same <column list>. This will work only if the values of the column list for the existing rows are unique or include a null value. ALTER TABLE <tablename> ADD [CONSTRAINT <constraintname>] PRIMARY KEY (<column list>); Adds a primary key constraint to the table, using the same constraint syntax as when the primary key is specified in a table definition. ALTER TABLE <tablename> ADD [CONSTRAINT <constraintname>] FOREIGN KEY (<column list>) REFERENCES <exptablename> (<column list>) [ON {DELETE | UPDATE} {CASCADE | SET DEFAULT | SET NULL}]; Adds a foreign key constraint to the table, using the same constraint syntax as when the foreign key is specified in a table definition. This will fail if for each existing row in the referring table, a matching row (with equal values for the column list) is not found in the referenced tables. ALTER TABLE <tablename> DROP CONSTRAINT <constraintname>; Drop a named unique, check or foreign key constraint from the table. ALTER TABLE <tablename> RENAME TO <newname>;
                ALTER USER<footnoteref linkend="posthyper" /> ALTER USER <username> SET PASSWORD <password>; Changes the password for an existing user. Password must be double quoted. Use "" for an empty password. DBA's may change users' base default schema name with the comand ALTER USER <username> SET INITIAL SCHEMA <schemaname>; This is the schema which database object names will resolve to for this user, unless overridden as explained in . For reasons of backwards compatibility, the initial schema value will not be persisted across database shutdowns until HSQLDB version 1.8.1. (I.e., INITIAL SCHEMA settings will be lost upon database shutdown with HSQLDB versions lower than version 1.8.1). Only an administrator may use these commands.
                CALL CALL Expression; Any expression can be called like a stored procedure, including, but not only Java stored procedures or functions. This command returns a ResultSet with one column and one row (the result) just like a SELECT statement with one row and one column. See also: , .
                CHECKPOINT CHECKPOINT [DEFRAG]; Closes the database files, rewrites the script file, deletes the log file and opens the database. If DEFRAG is specified, this command also shrinks the .data file to its minimal size. See also: , .
                COMMIT COMMIT [WORK]; Ends a transaction and makes the changes permanent. See also: , , .
                CONNECT CONNECT USER <username> PASSWORD <password>; Connects to the database as a different user. Password should be double quoted. Use "" for an empty password. See also: , .
                CREATE ALIAS CREATE ALIAS <function> FOR <javaFunction>; Creates an alias for a static Java function to be used as a Stored Procedure. The function must be accessible from the JVM in which the database runs. Example: CREATE ALIAS ABS FOR "java.lang.Math.abs"; The CREATE ALIAS command just defines the alias. It does not validate existence of the target method or its containing class. To validate the alias, use it. See also: , .
                CREATE INDEX CREATE [UNIQUE] INDEX <index> ON <table> (<column> [DESC] [, ...]) [DESC]; Creates an index on one or more columns in a table. Creating an index on searched columns may improve performance. The qualifier DESC can be present for command compatibility with other databases but it has no effect. Unique indexes can be defined but this is deprecated. Use UNIQUE constraints instead. The name of an index must be unique within the whole database. See also: , .
                CREATE ROLE<footnoteref linkend="posthyper" /> CREATE ROLE <rolename>; Creates the named role with no members. Requires Administrative privileges.
                CREATE SCHEMA<footnoteref linkend="posthyper" /> CREATE SCHEMA <schemaname> AUTHORIZATION <grantee> [<createStatement> [<grantStatement>] [...]; Creates the named schema, with ownership of the specified authorization. The authorization grantee may be a database user or a role. Optional (nested) CREATE and GRANT statements can be given only for new objects in this new schema. Only the last nested statement should be terminated with a semicolon, because the first semicolon encountered after "CREATE SCHEMA" will end the CREATE SCHEMA command. In the example below, a new schema, ACCOUNTS, is created, then two tables and a view are added to this schma and some rights on these objects are granted. CREATE SCHEMA ACCOUNTS AUTHORIZATION DBA CREATE TABLE AB(A INTEGER, ...) CREATE TABLE CD(C CHAHR, ...) CREATE VIEW VI AS SELECT ... GRANT SELECT TO PUBLIC ON AB GRANT SELECT TO JOE ON CD; Note that this example consists of one CREATE SCHEMA statement which is terminated by a semicolon. Requires Administrative privileges.
                CREATE SEQUENCE<footnoteref linkend="posthyper" /> CREATE SEQUENCE <sequencename> [AS {INTEGER | BIGINT}] [START WITH <startvalue>] [INCREMENT BY <incrementvalue>]; Creates a sequence. The default type is INTEGER. The default start value is 0 and the increment 1. Negative values are not allowed. If a sequence goes beyond Integer.MAXVALUE or Long.MAXVALUE, the next result is determined by 2's complement arithmetic. The next value for a sequence can be included in SELECT, INSERT and UPDATE statements as in the following example: SELECT [...,] NEXT VALUE FOR <sequencename> [, ...] FROM <tablename>; In the proposed SQL 200n and in the current version, there is no way of retreiving the last returned value of a sequence.
                CREATE TABLE CREATE [MEMORY | CACHED | [GLOBAL] TEMPORARY | TEMP | TEXT] TABLE <name> ( <columnDefinition> [, ...] [, <constraintDefinition>...] ) [ON COMMIT {DELETE | PRESERVE} ROWS]; Creates a tables in memory (default) or on disk and only cached in memory. If the database is all-in-memory, both MEMORY and CACHED forms of CREATE TABLE return a MEMORY table while the TEXT form is not allowed. Components of a CREATE TABLE command columnDefinition columnname Datatype [(columnSize[,precision])] [{DEFAULT <defaultValue> | GENERATED BY DEFAULT AS IDENTITY (START WITH <n>[, INCREMENT BY <m>])}] | [[NOT] NULL] [IDENTITY] [PRIMARY KEY] Default values that are allowed are constant values or certain SQL datetime functions. Allowed Default Values in Column Definitions For character column, a single-quoted string or NULL. The only SQL function that can be used is CURRENT_USER. For datetime columns, a single-quoted DATE, TIME or TIMESTAMP value or NULL. Or a datetime SQL function such as CURRENT_DATE, CURRENT_TIME, CURRENT_TIMESTAMP, TODAY, NOW. Each function is allowed for a certain datetime type. For BOOLEAN columns, the literals FALSE, TRUE, NULL. For numeric columns, any valid number or NULL. For binary columns, any valid hex string or NULL. Only one identity column is allowed in each table. Identity columns are autoincrement columns. They must be of INTEGER or BIGINT type and are automatically primary key columns (as a result, multi-column primary keys are not possible with an IDENTITY column present). Using the long SQL syntax the (START WITH <n>) clause specifies the first value that will be used. The last inserted value into an identity column for a connection is available using the function IDENTITY(), for example (where Id is the identity column): INSERT INTO Test (Id, Name) VALUES (NULL,'Test'); CALL IDENTITY(); constraintDefinition [CONSTRAINT <name>] UNIQUE ( <column> [,<column>...] ) | PRIMARY KEY ( <column> [,<column>...] ) | FOREIGN KEY ( <column> [,<column>...] ) REFERENCES <refTable> ( <column> [,<column>...]) [ON {DELETE | UPDATE} {CASCADE | SET DEFAULT | SET NULL}] | CHECK(<search condition>) Both ON DELETE and ON UPDATE clauses can be used in a single foreign key definition. search condition A search condition is similar to the set of conditions in a WHERE clause. In the current version of HSQLDB, the conditions for a CHECK constraint can only reference the current row, meaning there should be no SELECT statement. Sample table definitions with CHECK constraints are in TestSelfCheckConstraints.txt. This file is in the /hsqldb/testrun/hsqldb/ directory of the zip. General syntax limitations HSQLDB databases are initially created in a legacy mode that does not enforce column size and precision. You can set the property: sql.enforce_strict_size=true to enable this feature. When this property has been set, Any supplied column size and precision for numeric and character types (CHARACTER and VARCHAR) are enforced. Use the command, SET PROPERTY "sql.enforce_strict_size" TRUE once before defining the tables. NOT NULL constraints can be part of the column definition only. Other constraints cannot be part of the column definition and must appear at the end of the column definition list. TEMPORARY TABLE contents for each session (connection) are emptied by default at each commit or rollback. The optional qualifier ON COMMIT PRESERVE ROWS can be used to keep the rows while the session is open. The default is ON COMMIT DELETE ROWS. See also: .
                CREATE TRIGGER<footnoteref linkend="posthyper" /> CREATE TRIGGER <name> {BEFORE | AFTER} {INSERT | UPDATE | DELETE} ON <table> [FOR EACH ROW] [QUEUE n] [NOWAIT] CALL <TriggerClass>; TriggerClass is an application-supplied class that implements the org.hsqldb.Trigger interface e.g. "mypackage.TrigClass". It is the fire method of this class that is invoked when the trigger event occurs. You should provide this class, which can have any name, and ensure that this TriggerClass is present in the classpath which you use to start hsqldb. Since 1.7.2 the implementation has been changed and enhanced. When the 'fire' method is called, it is passed the following arguments: fire (String name, String table, Object row1[], Object row2[]) where 'row1' and 'row2' represent the 'before' and 'after' states of the row acted on, with each column being a member of the array. The mapping of members of the row arrays to database types is specified in . For example, BIGINT is represented by a java.lang.Long Object. Note that the number of elements in the row arrays could be larger than the number of columns by one or two elements. Never modify the last elements of the array, which are not part of the actual row. If the trigger method wants to access the database, it must establish its own JDBC connection. This can cause data inconsistency and other problems so it is not recommended. The jdbc:default:connection: URL is not currently supported. Implementation note: If QUEUE 0 is specified, the fire method is execued in the same thread as the database engine. This allows trigger action to alter the data that is about to be stored in the database. Data can be checked or modified in BEFORE INSERT / UPDATE + FOR EACH ROW triggers. All table constraints are then enforced by the database engine and if there is a violation, the action is rejected for the SQL command that initiated the INSERT or UPDATE. There is an exception to this rule, that is with UPDATE queries, referential integrity and cascading actions resulting from ON UPDATE CASCASE / SET NULL / SET DEFAULT are all performed prior to the invocation of the trigger method. If an invalid value that breaks referential integrity is inserted in the row by the trigger method, this action is not checked and results in inconsistent data in the table. Alternatively, if the trigger is used for external communications and not for checking or altering the data, a queue size larger than zero can be specified. This is in the interests of not blocking the database's main thread as each trigger will run in a thread that will wait for its firing event to occur. When this happens, the trigger's thread calls TriggerClass.fire. There is a queue of events waiting to be run by each trigger thread. This is particularly useful for 'FOR EACH ROW' triggers, when a large number of trigger events occur in rapid succession, without the trigger thread getting a chance to run. If the queue becomes full, subsequent additions to it cause the database engine to suspend awaiting space in the queue. Take great care to avoid this situation if the trigger action involves accessing the database, as deadlock will occur. This can be avoided either by ensuring the QUEUE parameter makes a large enough queue, or by using the NOWAIT parameter, which causes a new trigger event to overwrite the most recent event in the queue. The default queue size is 1024. Note also that the timing of trigger method calls is not guaranteed, so applications should implement their own synchronization measures if necessary. With a non-zero QUEUE parameter, if the trigger methods modifies the 'row2' values, these changes may or may not affect the database and will almost certainly result in data inconsistency. Please refer to the code for org.hsqldb.sample.Trigger and org.hsqldb.sample.TriggerSample for more information on how to write a trigger class. See also: .
                CREATE USER CREATE USER <username> PASSWORD <password> [ADMIN]; Creates a new user or new administrator in this database. Password must be double quoted. Empty password can be made using "". You can change a password afterwards using a command. Only an administrator can do this. See also: , , . ,
                CREATE VIEW<footnoteref linkend="posthyper" /> CREATE VIEW <viewname>[(<viewcolumn>,..) AS SELECT ... FROM ... [WHERE Expression] [ORDER BY orderExpression [, ...]] [LIMIT <limit> [OFFSET <offset>]]; A view can be thought of as either a virtual table or a stored query. The data accessible through a view is not stored in the database as a distinct object. What is stored in the database is a SELECT statement. The result set of the SELECT statement forms the virtual table returned by the view. A user can use this virtual table by referencing the view name in SQL statements the same way a table is referenced. A view is used to do any or all of these functions: Restrict a user to specific rows in a table. For example, allow an employee to see only the rows recording his or her work in a labor-tracking table. Restrict a user to specific columns. For example, allow employees who do not work in payroll to see the name, office, work phone, and department columns in an employee table, but do not allow them to see any columns with salary information or personal information. Join columns from multiple tables so that they look like a single table. Aggregate information instead of supplying details. For example, present the sum of a column, or the maximum or minimum value from a column. Views are created by defining the SELECT statement that retrieves the data to be presented by the view. The data tables referenced by the SELECT statement are known as the base tables for the view. In this example, is a view that selects data from three base tables to present a virtual table of commonly needed data: CREATE VIEW mealsjv AS SELECT m.mid mid, m.name name, t.mealtype mt, a.aid aid, a.gname + ' ' + a.sname author, m.description description, m.asof asof FROM meals m, mealtypes t, authors a WHERE m.mealtype = t.mealtype AND m.aid = a.aid; You can then reference mealsjv in statements in the same way you would reference a table: SELECT * FROM mealsjv; A view can reference another view. For example, mealsjv presents information that is useful for long descriptions that contain identifiers, but a short list might be all a web page display needs. A view can be built that selects only specific mealsjv columns: CREATE VIEW mealswebv AS SELECT name, author FROM mealsjv; The SELECT statement in a VIEW definition should return columns with distinct names. If the names of two columns in the SELECT statement are the same, use a column alias to distinguish between them. A list of new column names can always be defined for a view. CREATE VIEW aview (new_name, new_author) AS SELECT name, author FROM mealsjv See also: , , .
                DELETE DELETE FROM table [WHERE Expression]; Removes rows in a table. See also: , , .
                DISCONNECT DISCONNECT; Closes this connection. It is not required to call this command when using the JDBC interface: it is called automatically when the connection is closed. After disconnecting, it is not possible to execute other queries (including CONNECT) with this connection. See also: .
                DROP INDEX DROP INDEX index [IF EXISTS]; Removes the specified index from the database. Will not work if the index backs a UNIQUE of FOREIGN KEY constraint. See also: .
                DROP ROLE<footnoteref linkend="posthyper" /> DROP ROLE <rolename>; Removes all members from specified role, then removes the role itself.
                DROP SEQUENCE<footnoteref linkend="posthyper" /> DROP SEQUENCE <sequencename> [IF EXISTS] [RESTRICT | CASCADE]; Removes the specified sequence from the database. When IF EXIST is used, the statement returns without an error if the sequence does not exist. The RESTRICT option is in effect by default, meaning that DROP will fail if any view reference the sequence. Specify the CASCADE option to silently drop all dependent database objects.
                DROP SCHEMA<footnoteref linkend="posthyper" /> DROP SCHEMA <schemaname> [RESTRICT | CASCADE]; Removes the specified schema from the database. The RESTRICT option is in effect by default, meaning that DROP will fail if any objects such as tables or sequences have been defined in the schema. Specify the CASCADE option to silently drop all database objects in the schema. Requires Administrative privileges.
                DROP TABLE DROP TABLE <table> [IF EXISTS] [RESTRICT | CASCADE]; Removes a table, the data and indexes from the database. When IF EXIST is used, the statement returns without an error even if the table does not exist. The RESTRICT option is in effect by default, meaning that DROP will fail if any tables or views refer to this table. Specify the CASCADE option to silently drop all dependent views, and to drop any foreign key constraint that links this table with other tables. See also: .
                DROP TRIGGER DROP TRIGGER <trigger>; Removes a trigger from the database. See also: .
                DROP USER DROP USER <username>; Removes a user from the database. Only an administrator do this. See also: .
                DROP VIEW<footnoteref linkend="posthyper" /> DROP VIEW <viewname> [IF EXISTS] [RESTRICT | CASCADE]; Removes a view from the database. When IF EXIST is used, the statement returns without an error if the view does not exist. The RESTRICT option is in effect by default, meaning that DROP will fail if any other view refers to this view. Specify the CASCADE option to silently drop all dependent views. See also: .
                EXPLAIN PLAN EXPLAIN PLAN FOR { SELECT ... | DELETE ... | INSERT ... | UPDATE ..}; EXPLAIN PLAN FOR can be used with any query to get a detailed list of the elements in the execution plan. This list includes the indexes used for performing the query and can be used to optimise the query or to add indexes to tables.
                GRANT GRANT { SELECT | DELETE | INSERT | UPDATE | ALL } [,...] ON { table | CLASS "package.class" } TO <grantee>; GRANT <rolename> [,...] TO <grantee>; <grantee> is either a user name, a role name, or PUBLIC. PUBLIC means all users. The first form of the GRANT command assigns privileges to a grantee for a table or for a class. To allow a user to call a Store Procedure static function, the right ALL must be used. Examples: GRANT SELECT ON Test TO GUEST; GRANT ALL ON CLASS "java.lang.Math.abs" TO PUBLIC; Even though the command is GRANT ALL ON CLASS, you must specify a static method name. You are actually granting access to a static method, not to a class. The second form of the GRANT command gives the specified <grantee> membership in the specified role. Requires Administrative privileges. See also: , , .
                INSERT INSERT INTO table [( column [,...] )] { VALUES(Expression [,...]) | SelectStatement}; Adds one or more new rows of data into a table.
                REVOKE REVOKE { SELECT | DELETE | INSERT | UPDATE | ALL } [,...] ON { table | CLASS "package.class" } FROM <grantee>; REVOKE <rolename> [,...] FROM <grantee>; <grantee> is either a user name, a role name, or PUBLIC. PUBLIC means all users. The first form of the REVOKE command withdraws privileges from a grantee for a table or for a class. The second form of the REVOKE command withdraws membership of the specified <grantee> from the specified role. Both forms require Administrative privileges. See also: .
                ROLLBACK ROLLBACK [TO SAVEPOINT <savepoint name> | WORK}]; ROLLBACK used on its own, or with WORK, undoes changes made since the last COMMIT or ROLLBACK. ROLLBACK TO SAVEPOINT <savepoint name> undoes the change since the named savepoint. It has no effect if the savepoint is not found. See also: .
                SAVEPOINT<footnoteref linkend="posthyper" /> SAVEPOINT <savepoint name>; Sets up a SAVEPOINT for use with ROLLBACK TO SAVEPOINT. See also: .
                SCRIPT SCRIPT ['file']; Creates an SQL script describing the database. If the file is not specified, a result set containing only the DDL script is returned. If the file is specified then this file is saved with the path relative to the machine where the database engine is located. Only an administrator may do this.
                SELECT<footnoteref linkend="posthyper" /> SELECT [{LIMIT <offset> <limit> | TOP <limit>}][ALL | DISTINCT] { selectExpression | table.* | * } [, ...] [INTO [CACHED | TEMP | TEXT] newTable] FROM tableList [WHERE Expression] [GROUP BY Expression [, ...]] [HAVING Expression] [{ UNION [ALL | DISTINCT] | {MINUS [DISTINCT] | EXCEPT [DISTINCT] } | INTERSECT [DISTINCT] } selectStatement] [ORDER BY orderExpression [, ...]] [LIMIT <limit> [OFFSET <offset>]]; Retrieves information from one or more tables in the database. Components of a SELECT command tableList table [{CROSS | INNER | LEFT OUTER | RIGHT OUTER} JOIN table ON Expression] [, ...] table { (selectStatement) [AS] label | tableName} selectExpression { Expression | COUNT(*) | { COUNT | MIN | MAX | SUM | AVG | SOME | EVERY | VAR_POP | VAR_SAMP | STDDEV_POP | STDDEV_SAMP } ([ALL | DISTINCT]] Expression) } [[AS] label] If DISTINCT is specified, only one instance of several equivalent values is used in the aggregate function. Except COUNT(*), all aggregate functions exclude NULL values. The type of the returned value for SUM is subject to deterministic widenning to ensure lossless results. The returned value type for COUNT is INTEGER, for MIN, MAX and AVG it is the same type as the column, for SOME and EVERY it is BOOLEAN. For VAR_POP, VAR_SAMP, STDDEV_POP and STDDEV_SAMP statistical functions, the type is always DOUBLE. These statistical functions do not allow ALL or DISTINCT qualifiers. If CROSS JOIN is specified no ON expression is allowed for the join. orderExpression { columnNr | columnAlias | selectExpression } [ASC | DESC] LIMIT n m Creates the result set for the SELECT statement first and then discards the first n rows (OFFSET) and returns the first m rows of the remaining result set (LIMIT). Special cases: LIMIT 0 m is equivalent to TOP m or FIRST m in other RDBMS's; LIMIT n 0 discards the first n rows and returns the rest of the result set. LIMIT m OFFSET n This form is used at the end of the SELECT statement. The OFFSET term is optional. TOP m Equivalent to LIMIT 0 m. UNION and other set operations Multiple SELECT statements joined with UNION, EXCEPT and INTERSECT are possible. Each SELECT is then treated as a term, and the set operation as an operator in an expression. The expression is evaluated from left to right but INTERSECT takes precedence over the rest of the operators and is applied first. You can use parentheses around any number of SELECT statements to change the evaluation order. See also: , , .
                SET AUTOCOMMIT SET AUTOCOMMIT { TRUE | FALSE }; Switches on or off the connection's auto-commit mode. If switched on, then all statements will be committed as individual transactions. Otherwise, the statements are grouped into transactions that are terminated by either COMMIT or ROLLBACK. By default, new connections are in auto-commit mode. This command should not be used directly. Use the JDBC equivalent method, Connection.setAutoCommit(boolean autocommit).
                SET DATABASE COLLATION<footnoteref linkend="posthyper" /> SET DATABASE COLLATION <double quoted collation name>; Each database can have its own collation. Sets the collation from the set of collations in the source for org.hsqldb.Collation. Once this command has been issued, the database can be opened in any JVM and will retain its collation.
                SET CHECKPOINT DEFRAG<footnoteref linkend="posthyper" /> SET CHECKPOINT DEFRAG <size>; The parameter size is the megabytes of abandoned space in the .data file. When a CHECKPOINT is performed either as a result of the .log file reaching the limit set by "SET LOGSIZE size", or by the user issuing a CHECKPOINT command, the amount of space abandoned during the session is checked and if it is larger than size, a CHECKPOINT DEFRAG is performed instead of a checkpoint.
                SET IGNORECASE SET IGNORECASE { TRUE | FALSE }; Disables (ignorecase = true) or enables (ignorecase = false) the case sensitivity of text comparison and indexing for new tables. By default, character columns in new databases are case sensitive. The sensitivity must be switched before creating tables. Existing tables and their data are not affected. When switched on, the data type VARCHAR is set to VARCHAR_IGNORECASE in new tables. Alternatively, you can specify the VARCHAR_IGNORECASE type for the definition of individual columns. So it is possible to have some columns case sensitive and some not, even in the same table. Only an administrator may do this.
                SET INITIAL SCHEMA <footnoteref linkend="posthyper" /> Users may change their base default schema name with the comand SET INITIAL SCHEMA <schemaname>; This is the schema which database object names will resolve to for the current user, unless overridden as explained in . For reasons of backwards compatibility, the initial schema value will not be persisted across database shutdowns until HSQLDB version 1.8.1. (I.e., INITIAL SCHEMA settings will be lost upon database shutdown with HSQLDB versions lower than version 1.8.1).
                SET LOGSIZE SET LOGSIZE <size>; Sets the maximum size in MB of the .log file. Default is 200 MB. The database will be closed and opened (just like using CHECKPOINT) if the .log file gets over this limit, and so the .log file will shrink. 0 means no limit. See also: .
                SET MAXROWS SET MAXROWS <maxwors>; Describe me!
                SET PASSWORD SET PASSWORD <password>; Changes the password of the currently connected user. Password must be double quotedEmpty password can be set using "".
                SET PROPERTY<footnoteref linkend="posthyper" /> SET PROPERTY <double quoted name> <value>; Sets a database property. Properties that can be set using this command are either boolean or integral and are listed in the chapter.
                SET READONLY SET READONLY {TRUE|FALSE}; Describe me!
                SET REFERENTIAL INTEGRITY SET REFERENTIAL_INTEGRITY { TRUE | FALSE }; This commands enables / disables the referential integrity checking (foreign keys). Normally it should be switched on (this is the default) but when importing data (and the data is imported in the 'wrong' order) the checking can be switched off. Note that when referential integrity is switched back on, no check is made that the changes to the data are consistent with the existing referential integrity constraints. You can verify consistency using SQL queries and take appropriate actions. Only an administrator may do this. See also: .
                SET SCHEMA<footnoteref linkend="posthyper" /> SET SCHEMA <schemaname>; Sets the current JDBC session's schema. The sole purpose for the session schema is to provide a default schema name for schema objects that do not have the schema name specified explicitly in the SQL command, or by association with another object of known schema. For example, if you run SELECT * FROM atbl;, HSQLDB will look for the table or view named atbl in the session's current schema. Session schemas last only for the duration of the current session. When a new JDBC session is obtained, the new session will have the default schema.
                SET SCRIPTFORMAT<footnoteref linkend="posthyper" /> SET SCRIPTFORMAT {TEXT | BINARY | COMPRESSED}; Changes the format of the script file. BINARY and COMPRESSED formats are slightly faster and more compact than the default TEXT. Recommended only for very large script files.
                SET TABLE INDEX SET TABLE tableName INDEX 'index1rootPos index2rootPos ... '; This command is only used internally to store the position of index roots in the .data file. It appears only in database script files; it should not be used directly.
                SET TABLE READONLY<footnoteref linkend="posthyper" /> SET TABLE <tablename> READONLY {TRUE | FALSE}; Sets the table as read only.
                SET TABLE SOURCE<footnoteref linkend="posthyper" /> SET TABLE <tablename> SOURCE <file and options> [DESC]; For details see the chapter. This command is used exclusively with TEXT tables to specify which file is used for storage of the data. The optional DESC qualifier results in the text file indexed from the end and opened as readonly. The <file and options> argument is a double quoted string that consists of: <file and options>::= <doublequote> <filepath> [<semicolon> <option>...] <doublequote> Example: SET TABLE mytable SOURCE "myfile;fs=|;vs=.;lvs=~" Supported Properties quoted = { true | false } default is true. If false, treats double quotes as normal characters all_quoted = { true | false } default is false. If true, adds double quotes around all fields. encoding = <encoding name> character encoding for text and character fields, for example, encoding=UTF-8 ignore_first = { true | false } default is false. If true ignores the first line of the file cache_scale= <numeric value> exponent to calculate rows of the text file in cache. Default is 8, equivalent to nearly 800 rows cache_size_scale = <numeric value>r exponent to calculate average size of each row in cache. Default is 8, equivalent to 256 bytes per row. fs = <unquoted character> field separator vs = <unquoted character> varchar separator lvs = <unquoted character> long varchar separator Special indicators for Hsqldb Text Table separators \semi semicolon \quote quote \space space character \apos apostrophe \n newline - Used as an end anchor (like $ in regular expressions) \r carriage return \t tab \\ backslash \u#### a Unicode character specified in hexadecimal Only an administrator may do this.
                SET WRITE DELAY<footnoteref linkend="posthyper" /> SET WRITE_DELAY {{ TRUE | FALSE } | <seconds> | <milliseconds> MILLIS}; This controls the frequency of file sync for the log file. When WRITE_DELAY is set to FALSE or 0, the sync takes place immediately at each COMMIT. WRITE_DELAY TRUE performs the sync once every 20 seconds (which is the default). A numeric value can be specified instead. The purpose of this command is to control the amount of data loss in case of a total system crash. A delay of 1 second means at most the data written to disk during the last second before the crash is lost. All data written prior to this has been synced and should be recoverable. A write delay of 0 impacts performance in high load situations, as the engine has to wait for the file system to catch up. To avoid this, you can set write delay down to 10 milliseconds. In practice, a write delay of 100 milliseconds provides better than 99.9999% reliability with an average one system crash per day, or 99.99999% with an average one system crash per 6 days. Each time a SET WRITE_DELAY is issued with any value, a sync is immediately performed. Only an administrator may do this.
                SHUTDOWN SHUTDOWN [IMMEDIATELY | COMPACT | SCRIPT]; Closes the current database. Varieties of the SHUTDOWN command SHUTDOWN Performs a checkpoint to creates a new .script file that has the minimum size and contains the data for memory tables only. It then backs up the .data file containing the CACHED TABLE data in zipped format to the .backup file and closes the database. SHUTDOWN IMMEDIATELY Just closes the database files (like when the Java process for the database is terminated); this command is used in tests of the recovery mechanism. This command should not be used as the routine method of closing the database. SHUTDOWN COMPACT Writes out a new .script file which contains the data for all the tables, including CACHED and TEXT tables. It then deletes the existing text table files and the .data file before rewriting them. After this, it backs up the .data file in the same way as normal SHUTDOWN. This operation shrinks all files to the minimum size. SHUTDOWN SCRIPT Similar to SHUTDOWN COMPACT but after writing the script and deleting the existing files, it does not rewrite the .data and text table files. After SHUTDOWN SCRIPT, only the .script and .properties file remain. At the next startup, these files are processed and the .data and .backup files are created. This command in effect performs part of the job of SHUTDOWN COMPACT, leaving the other part to be performed automatically at the next startup. This command produces a full script of the database which can be edited for special purposes prior to the next startup. Only an administrator may use the SHUTDOWN command.
                UPDATE UPDATE table SET column = Expression [, ...] [WHERE Expression]; Modifies data of a table in the database. See also: , , .
                Schema object naming Schema objects are database objects that are always scoped to a specific schema. Each schema has a namespace. There may be multiple schema objects of the same name, each in the namespace of a different schema. A particular schema object may nearly always be uniquely identified using the notation schemaname.objectname. All HSQLDB database objects are schema objects, other than the following. HSQLDB Non-Schema Object Types Users Roles Store Procedure Java Classes HSQL Aliases Our current Java-class-based Triggers are not fully schema objects. However, we are in the process of implementing SQL-conformant triggers which will encompass our Java-class-based triggers. When this work is completed, HSQLDB triggers will be schema objects. Sequences are schema objects with creation and removal permission governed by schema authorization (as described hereafter), but GRANT and REVOKE command do not work yet for sequences. In a future version of HSQLDB, sequence GRANTs and REVOKEs will work similarly to the current GRANT and REVOKE commands for table access. Most of the time, you do not need to specify the schema for the desired schema object, because the implicit schema is usually the only one that can be used. For example, when creating an index, the target schema will default to that of the table which is the target of the index. Named constraints are an extreme example of this. There is never a need to specify a schema name for a constraint, since constraint names are only specified in a CREATE or ALTER TABLE command, and the schema must be that of the target table. If the implicit schema is not determined by a related object, then the default comes from your JDBC session's current schema setting. The session schema value will be your login user's initial schema, or whatever you last set it to with in your current JDBC session with the SET SCHEMA command. (Your initial schema is "PUBLIC" unless changed with the ALTER USER SET INITIAL SCHEMA or the command). In addition to namespace scoping, there are permission aspects to the schema of a database object. The authorization of a schema is a role or user that is basically the owner of the schema. Only a user with the DBA role (an admin user) or the owner of a schema may create objects, or modify the DDL of objects, in the namespace of that schema. In this way, a schema authorization is said to "own" the objects of that schema. A schema authorization/owner can be a role or a user (even a role with no members). The two schemas automatically created when a database is initialized are both owned by the role DBA. An important implication to database objects being owned by the schema owner is, if a non-DBA database user is to have permission to create any database object, they must have ownership of a schema. To allow a user to create (or modify DDL of) objects in their own personal schema, you would create a new schema with that user as the authorization. To allow a non-DBA user to share create and DDL privileges in some schema, you would create this schema with a role as the authorization, then GRANT this role to all of the desired users. The INFORMATION_SCHEMA is a system defined schema that contains the system tables for the database. This schema is read-only. When a database is created, a shema named PUBLIC is automatically created as the default schma. This schema has the authorization DBA. You can change the name of this schema. If all non-system schemas are dropped from a database, an empty PUBLIC schema is created again. So each database always has at least one non-system schema.
                Data Types Data Types. The types on the same line are equivalent.Data Types Name Range Java Type INTEGER | INT as Java type int | java.lang.Integer DOUBLE [PRECISION] | FLOAT as Java type double | java.lang.Double VARCHAR as Integer.MAXVALUE java.lang.String VARCHAR_IGNORECASE as Integer.MAXVALUE java.lang.String CHAR | CHARACTER as Integer.MAXVALUE java.lang.String LONGVARCHAR as Integer.MAXVALUE java.lang.String DATE as Java type java.sql.Date TIME as Java type java.sql.Time TIMESTAMP | DATETIME as Java type java.sql.Timestamp DECIMAL No limit java.math.BigDecimal NUMERIC No limit java.math.BigDecimal BOOLEAN | BIT as Java type boolean | java.lang.Boolean TINYINT as Java type byte | java.lang.Byte SMALLINT as Java type short | java.lang.Short BIGINT as Java type long | java.lang.Long REAL as Java type double | java.lang.Double BINARY as Integer.MAXVALUE byte[] VARBINARY as Integer.MAXVALUE byte[] LONGVARBINARY as Integer.MAXVALUE byte[] OTHER | OBJECT as Integer.MAXVALUE java.lang.Object
                The uppercase names are the data types names defined by the SQL standard or commonly used by RDMS's. The data types in quotes are the Java class names - if these type names are used then they must be enclosed in quotes because in Java names are case-sensitive. Range indicates the maximum size of the object that can be stored. Where Integer.MAXVALUE is stated, this is a theoretical limit and in practice the maximum size of a VARCHAR or BINARY object that can be stored is dictated by the amount of memory available. In practice, objects of up to a megabyte in size have been successfully used in production databases. The recommended Java mapping for the JDBC datatype FLOAT is as a Java type "double". Because of the potential confusion it is recommended that DOUBLE is used instead of FLOAT. VARCHAR_IGNORECASE is a special case-insensitive type of VARCHAR. This type is not portable. In table definition statements, HSQLDB accepts size, precision and scale qualifiers only for certain types: CHAR(s), VARCHAR(s), DOUBLE(p), NUMERIC(p), DECIMAL(p,s) and TIMESTAMP(p). TIMESTAMP(p) can take only 0 or 6 as precision. Zero indicates no subsecond part. Without the precision, the default is 6. By default specified precision and scale for the column is simply ignored by the engine. Instead, the values for the corresponding Java types are always used, which in the case of DECIMAL is an unlimited precision and scale. If a size is specified, it is stored in the database definition but is not enforeced by default. Once you have created the database (before adding data), you can add a database property value to enforce the sizes: SET PROPERTY "sql.enforce_strict_size" true This will enforce the specified size and pad CHAR fields with spaces to fill the size. This complies with SQL standards by throwing an exception if an attempt is made to insert a string longer than the maximum size. It also results in all DECIMAL values conforming to the specified precision and scale. CHAR and VARCHAR and LONGVARCHAR columns are by default compared and sorted according to POSIX standards. See the section above to modify this behavior. The property sql.compare_in_locale is no longer supported. Instead, you can define a collation to be used for all character comparisons. Columns of the type OTHER or OBJECT contain the serialized form of a Java Object in binary format. To insert or update such columns, a binary format string (see below under Expression) should be used. Using PreparedStatements with JDBC automates this transformation.
                SQL Comments -- SQL style line comment // Java style line comment /* C style line comment */ All these types of comments are ignored by the database.
                Stored Procedures / Functions Stored procedures are static Java functions that are called directly from the SQL language or using an alias. Calling Java functions (directly or using the alias) requires that the Java class can be reached by the database (server). The syntax is: "java.lang.Math.sqrt"(2.0) This means the package must be provided, and the name must be written as one word, and inside " because otherwise it is converted to uppercase (and not found). An alias can be created using the command CREATE ALIAS: CREATE ALIAS SQRT FOR "java.lang.Math.sqrt"; When an alias is defined, then the function can be called additionally using this alias: SELECT SQRT(A) , B FROM MYTABLE; Only static java methods can be used as stored procedures. If, within the same class, there are overloaded methods with the same number of arguments, then the first one encountered by the program will be used. If you want to use Java library methods, it is recommended that you create your own class with static methods that act as wrappers around the Java library methods. This will allow you to control which method signature is used to call each Java library method.

                SQL Expression [NOT] condition [{ OR | AND } condition] Components of SQL Expressions condition { value [|| value] | value { = | < | <= | > | >= | <> | != } value | value IS [NOT] NULL | EXISTS(selectStatement) | value BETWEEN value AND value | value [NOT] IN ( {value [, ...] | selectStatement } ) | value [NOT] LIKE value [ESCAPE] value } value [+ | -] { term [{ + | - | * | / | || } term] | ( condition ) | function ( [parameter] [,...] ) | selectStatement giving one value | {ANY|ALL} (selectStatement giving single column) term { 'string' | number | floatingpoint | [table.]column | TRUE | FALSE | NULL } sequence NEXT VALUE FOR <sequence> HSQLDB does not currently enforce the SQL 200n proposed rules on where sequence generated values are allowed to be used. In general, these values can be used in insert and update statements but not in CASE statements, order by clauses, search conditions, aggregate functions, or grouped queries. string Strings in HSQLDB are Unicode strings. A string starts and ends with a single ' (singlequote). In a string started with ' (singlequote) use '' (two singlequotes) to create a ' (singlequote). String contatenation should be performed with the standard SQL operator || rather than the non-standard + operator. The LIKE keyword uses '%' to match any (including 0) number of characters, and '_' to match exactly one character. To search for '%' or '_' itself an escape character must also be specified using the ESCAPE clause. For example, if the backslash is the escaping character, '\%' and '\_' can be used to find the '%' and '_' characters themselves. For example, SELECT .... LIKE '\_%' ESCAPE '\' will find the strings beginning with an underscore. name The character set for quoted identifiers (names) in HSQLDB is Unicode. A unquoted identifier (name) starts with a letter and is followed by any number of ASCII letters or digits. When an SQL statement is issued, any lowercase characters in unquoted identifiers are converted to uppercase. Because of this, unquoted names are in fact ALL UPPERCASE when used in SQL statements. An important implication of this is the for accessing columns names via JDBC DatabaseMetaData: the internal form, which is the ALL UPPERCASE must be used if the column name was not quoted in the CREATE TABLE statement. Quoted identifiers can be used as names (for tables, columns, constraints or indexes). Quoted identifiers start and end with " (one doublequote). A quoted identifier can contain any Unicode character, including space. In a quoted identifier use "" (two doublequotes) to create a " (one doublequote). With quoted identifiers it is possible to create mixed-case table and column names. Example: CREATE TABLE "Address" ("Nr" INTEGER,"Name" VARCHAR); SELECT "Nr", "Name" FROM "Address"; The equivalent quoted identifier can be used for an unquoted identifer by converting the identifier to all uppercase and quoting it. For example, if a table name is defined as Address2 (unquoted), it can be referred to by its quoted form, "ADDRESS2", as well as address2, aDDress2 and ADDRESS2. Quoted identifiers should not be confused with SQL strings. Quoting can sometimes be used for identifiers, aliases or functions when there is an ambiguity. For example: SELECT COUNT(*) "COUNT" FROM MYTABLE; SELECT "LEFT"(COL1, 2) FROM MYTABLE; Although HSQLDB 1.8.0 does not force unquoted identifiers to contain only ASCII characters, the use of non-ASCII characters in these identifiers does not comply with SQL standards. Portability between different JRE locales could be an issue when accented characters (or extended unicode characters) are used in unquoted identifiers. Because native Java methods are used to convert the identifier to uppercase, the result may vary not be expected in different locales. It is recommended that accented characters are used only in quoted identifiers. When using JDBC DatabaseMetaData methods that take table, column, or index identifiers as arguments, treat the names as they are registered in the database. With these methods, unquoted identifiers should be used in all-uppercase to get the correct result. Quoted identifiers should be used in the exact case combination as they were defined - no quote character should be included around the name. JDBC methods that return a result set containing such identifiers return unquoted identifiers as all-uppercase and quoted identifiers in the exact case they are registered in the database (a change from 1.6.1 and previous versions). Please also note that the JDBC getXXX(String columnName) methods interpret the columnName as case-independent. This is a general feature of JDBC and not specific to HSQLDB. password Passwords must be double quoted and used consistently. Passwords are case insensitive only for backward compatibility. This may change in future versions. values A DATE literal starts and ends with ' (singlequote), the format is yyyy-mm-dd (see java.sql.Date. A TIME liteal starts and ends with ' (singlequote), the format is hh:mm:ss (see java.sql.Time). A TIMESTAMP or DATETIME literal starts and ends with ' (singlequote), the format is yyyy-mm-dd hh:mm:ss.SSSSSSSSS (see java.sql.Timestamp). When specifying default values for date / time columns in CREATE TABLE statements, or in SELECT,INSERT, and UPDATE statements, special SQL functions: NOW, SYSDATE, TODAY, CURRENT_TIMESTAMP, CURRENT_TIME and CURRENT_DATE (case independent) can be used. NOW is used for TIME and TIMESTAMP columns, TODAY is used for DATE columns. The data and time variants CURRENT_* are SQL standard versions and should be used in preference to others. Example: CREATE TABLE T(D DATE DEFAULT CURRENT_DATE); CREATE TABLE T1(TS TIMESTAMP DEFAULT CURRENT_TIMESTAMP); Binary data starts and ends with ' (singlequote), the format is hexadecimal. '0004ff' for example is 3 bytes, first 0, second 4 and last 255 (0xff). Any number of commands may be combined. With combined commands, ';' (semicolon) must be used at the end of each command to ensure data integrity, despite the fact that the engine may understand the end of commands and not return an error when a semicolon is not used.

                Purpose This chapter explains how to quickly install, run, and use HSQLDB on UNIX. HSQLDB has lots of great optional features. I intend to cover very few of them. I do intend to cover what I think is the most common UNIX setup: To run a multi-user database with permament data persistence. (By the latter I mean that data is stored to disk so that the data will persist across database shutdowns and startups). I also cover how to run HSQLDB as a system daemon.
                Installation Go to and click on the "files" link. You want the current version. This will be the highest numbered version under the plain black "hsqldb" heading. See if there's a distribution for the current HSQLDB version in the format that you want. If you want an rpm, you should still find out the current version of HSQLDB as described in the previous paragraph. Then click "hsqldb" in the "free section" of and see if they have the current HSQLDB version built yet. Hopefully, the JPackage folk will document what JVM versions their rpm will support (currently they document this neither on their site nor within the package itself). (I really can't document how to download from a site that is totally beyond my control). It could very well happen that some of the file formats which I discuss below are not in fact offered. If so, then we have not gotten around to building them. Binary installation depends on the package format that you downloaded. Installing from a .pkg.Z file This package is only for use by a Solaris super-user. It's a System V package. Download then uncompress the package with uncompress or gunzip uncompress filename.pkg.Z You can read about the package by running pkginfo -l -d filename.pkg Run pkgadd as root to install. pkgadd -d filename.pkg Installing from a .rpm file This is a Linux rpm package. After you download the rpm, you can read about it by running rpm -qip /path/to/file.rpm Rpms can be installed or upgraded by running rpm -Uvh /path/to/file.rpm as root. Suse users may want to keep Yast aware of installed packages by running rpm through Yast: yast2 -i /path/to/file.rpm. Installing from a .zip file Extract the zip file to the parent directory of the new HSQLDB home. You don't need to create the HSQLDB_HOME directory because the extraction will create it for you with the right name) cd parent/of/new/hsqldb/home unzip /path/to/file.zip All the files in the zip archive will be extracted to underneath a new hsqldb directory. Take a look at the files you installed. (Under hsqldb for zip file installations. Otherwise, use the utilities for your packaging system). The most important file of the hsqldb system is hsqldb.jar, which resides in the directory lib. For the purposes of this chapter, I define HSQLDB_HOME to be the parent directory of the lib directory that contains hsqldb.jar. E.g., if your path to hsqldb.jar is /a/b/hsqldb/lib/hsqldb.jar, then your HSQLDB_HOME is /a/b/hsqldb. If the description of your distribution says that the hsqldb.jar file will work for your Java version, then you are finished with installation. Otherwise you need to build a new hsqldb.jar file. If you followed the instructions above and you still don't know what Java version your hsqldb.jar supports, then read HSQLDB_HOME/readme.txt and HSQLDB_HOME/index.html. If that still doesn't help, then you can just try your hsqldb.jar and see if it works, or build your own. To use the supplied hsqldb.jar, just skip to the next section of this document. Otherwise build a new hsqldb.jar. Building hsqldb.jar If you don't already have Ant, download the latest stable binary version from . cd to where you want Ant to live, and extract from the archive with unzip /path/to/file.zip or tar -xzf /path/to/file.tar.gz or bunzip2 -c /path/to/file.tar.bz2 | tar -xzf - Everything will be installed into a new subdirectory named apache-ant- + version. You can rename the directory after the extraction if you wish. Set the environmental variable JAVA_HOME to the base directory of your Java JRE or SDK, like export JAVA_HOME; JAVA_HOME=/usr/java/j2sdk1.4.0 The location is entirely dependent upon your variety of UNIX. Sun's rpm distributions of Java normally install to /usr/java/something. Sun's System V package distributions of Java (including those that come with Solaris) normally install to /usr/something, with a sym-link from /usr/java to the default version (so for Solaris you will usually set JAVA_HOME to /usr/java). Remove the existing file HSQLDB_HOME/lib/hsqldb.jar. cd to HSQLDB_HOME/build. Make sure that the bin directory under your Ant home is in your search path. Run the following command. ant hsqldb This will build a new HSQLDB_HOME/lib/hsqldb.jar. See the appendix if you want to build anything other than hsqldb.jar with all default settings.
                Setting up a Hsqldb Persistent Database Instance and a Hsqldb Server Setting up Database Instance and Server If you installed from an OS-specific package, you may already have a database instance and server pre-configured. See if your package includes a file named server.properties (make use of your packaging utilities). If you do, then I suggest that you still read this section while you poke around, in order to understand your setup. Select a UNIX user to run the database as. If this database is for the use of multiple users, or is a production system (or to emulate a production system), you should dedicate a UNIX user for this purpose. In my examples, I use the user name hsqldb. In this chapter, I refer to this user as the HSQLDB_OWNER, since that user will own the database instance files and processes. If the account doesn't exist, then create it. On all system-5 UNIXes and most hybrids (including Linux), you can run (as root) something like useradd -c 'HSQLDB Database Owner' -s /bin/bash -m hsqldb (BSD-variant users can use a similar pw useradd hsqldb... command). Become the HSQLDB_OWNER. Copy the sample file HSQLDB_HOME/src/org/hsqldb/sample/sample-server.properties to the HSQLDB_OWNER's home directory and rename it to server.properties. &sample-server.properties-cdata; Since the value of the first database (server.database.0) begins with file:, the database instance will be persisted to a set of files in the specified directory with names beginning with the specified name. Set the path to whatever you want (relative paths will be relative to the directory containing the properties file). You can read about how to specify other database instances of various types, and how to make settings for the listen port and many other things, in the chapter. Set and export the environmental variable CLASSPATH to the value of HSQLDB_HOME (as described above) plus "/lib/hsqldb.jar", like export CLASSPATH; CLASSPATH=/path/to/hsqldb/lib/hsqldb.jar In HSQLDB_OWNER's home directory, run nohup java org.hsqldb.Server & This will start the Server process in the background, and will create your new database instance "db0". Continue on when you see the message containing HSQLDB server... is online. nohup just makes sure that the command will not quit when you exit the current shell (omit it if that's what you want to do).
                Accessing your Database Copy the file HSQLDB_HOME/src/org/hsqldb/sample/sqltool.rc to the HSQLDB_OWNER's home directory. Use chmod to make the file readable and writable only to HSQLDB_OWNER. &sqltool.rc-cdata; We will be using the "localhost-sa" sample urlid definition from the config file. The JDBC URL for this urlid is jdbc:hsqldb:hsql://localhost. That is the URL for the default database instance of a HSQLDB Server running on the default port of the local host. You can read about URLs to connect to other instances and other servers in the chapter. Run SqlTool. java -jar path/to/hsqldb.jar localhost-sa If you get a prompt, then all is well. If security is of any concern to you at all, then you should change the privileged password in the database. Use the command SET PASSWORD command to change SA's password. set password "newpassword"; When you're finished playing, exit with the command \q. If you changed the SA password, then you need to fix the password in the sqltool.rc file accordingly. You can, of course, also access the database with any JDBC client program. See the appendix. You will need to modify your classpath to include hsqldb.jar as well as your client class(es). You can also use the other HSQLDB client programs, such as org.hsqldb.util.DatabasManagerSwing, a graphical client with a similar purpose to SqlTool. You can use any normal UNIX account to run the JDBC clients, including SqlTool, as long as the account has read access to the hsqldb.jar file and to an sqltool.rc file. See the chapter about where to put sqltool.rc, how to execute sql files, and other SqlTool features.
                Create additional Accounts Connect to the database as SA (or any other Administrative user) and run CREATE USER to create new accounts for your database instance. HSQLDB accounts are database-instance-specific, not Server-specific. For the current version of HSQLDB, only users with Role of DBA may create or own database objects. DBA members have privileges to do anything. Non-DBAs may be granted some privileges, but may never create or own database objects. (Before long, non-DBAs will be able to create objects if they have permission to do so in the target schema). When you first create a hsqldb database, it has only one database user-- SA, a DBA account, with an empty string password. You should set a password (as described above). You can create as many additional users as you wish. To make a user a DBA, you can use the "ADMIN" option to the CREATE USER command, or GRANT the DBA Role to the account after creating it. If you create a user without the ADMIN tag (and without granting the DBA role to them) this user will be able to read the data dictionary tables, but will be able unable to create or own his own objects. He will have only the rights which the pseudo-user PUBLIC has. To give him more permissions, even rights to read objects, you can GRANT permissions for specific objects, grant Roles (which encompass a set of permissions), or grant the DBA Role itself. Since only people with a database account may do anything at all with the database, it is often useful to permit other database users to view the data in your tables. To optimize performance, reduce contention, and minimize administration, it is often best to grant SELECT to PUBLIC on any object that needs to be accessed by multiple database users (with the significant exception of any data which you want to keep secret).
                Shutdown Do a clean database shutdown when you are finished with the database instance. You need to connect up as SA or some other Admin user, of course. With SqlTool, you can run java -jar path/to/hsqldb.jar --sql shutdown localhost-sa You don't have to worry about stopping the Server because it shuts down automatically when all served database instances are shut down.
                Running Hsqldb as a System Daemon You can, of course, run HSQLDB through inittab on System V UNIXes, but usually an init script is more convenient and manageable. This section explains how to set up and use our UNIX init script. Our init script is only for use by root. (That is not to say that the Server will run as root-- it usually should not). The main purpose of the init script is to start up a Server with the database instances specified in your server.properties file; and to shut down all of those instances plus additional urlids which you may (optionally) list in your init script config file. These urlids must all have entries in a sqltool.rc file. If, due to firewall issues, you want to run a WebServer instead of a Server, then make sure you have a healthy WebServer with a webserver.properties set up, adjust your URLs in sqltool.rc, and set TARGET_CLASS in the config file. (By following the commented examples in the config file, you can start up any number of Server and/or WebServer listeners with or without TLS ecryption). After you have the init script set up, root can use it anytime to start or stop HSQLDB. (I.e., not just at system bootup or shutdown).
                Portability of <filename>hsqldb</filename> init script The primary design criterion of the init script is portability. It does not print pretty color startup/shutdown messages as is common in late-model Linuxes and HPUX; and it does not keep subsystem state files or use the startup/shutdown functions supplied by many UNIXes, because these features are all non-portable. Offsetting these limitations, this one script does it's intended job great on the UNIX varieties I have tested, and can easily be modified to accommodate other UNIXes. While you don't have tight integration with OS-specific daemon administration guis, etc., you do have a well tested and well behaved script that gives good, utilitarian feedback.
                Init script Setup Procedure The strategy taken here is to get the init script to run your single Server or WebServer first (as specified by TARGET_CLASS). After that's working, you can customize the JVM that is run by running additional Servers in it, running your own application in it (embedding), or even overriding HSQLDB behavior with your own overriding classes. Copy the init script hsqldb from HSQLDB_HOME/bin into the directory where init scripts live on your variety of UNIX. The most common locations are /etc/init.d or /etc/rc.d/init.d on System V style UNIXes, /usr/local/etc/rc.d on BSD style UNIXes, and /Library/StartupItems/hsqldb on OS X (you'll need to create the directory for the last). Look at the comment towards the top of the init script which lists recommended locations for the configuration file for various UNIX platforms. Copy the sample config file HSQLDB_HOME/src/org/hsqldb/sample/sample-hsqldb.cfg to one of the listed locations (your choice). Edit the config file according to the instructions in it. &sample-hsqldb.cfg-cdata; Either copy HSQLDB_OWNER's sqltool.rc file into root's home directory, or set the value of AUTH_FILE to the absolute path of HSQLDB_OWNER's sqltool.rc file. This file is read (for stops) directly by root, even if you run hsqldb as non-root (by setting HSQLDB_OWNER in the config file). If you copy the file, make sure to use chmod to restrict permissions on the new copy. (The init script now enforces permissions on this file). Edit your server.properties file. For every server.database.X that you have defined, set a property of name server.urlid.X to the urlid for an Administrative user for that database instance. server.properties fragment server.database.0=file://home/hsqldb/data/db1 server.urlid.0=localhostdb1 Make sure to add a urlid for each and every database instance. If you don't then the init script will never know about databases that become inaccessible and will give false diagnostics. For this example, you would need to define the urlid localhostdb1 in your sqltool.rc file. example sqltool.rc stanza urlid localhostdb1 url jdbc:hsqldb:hsql://localhost username sa password secret Verify that the init script works. Just run /path/to/hsqldb as root to see the arguments you may use. Notice that you can run /path/to/hsqldb status at any time to see whether your HSQLDB Server is running. Re-run the script with each of the possible arguments to really test it good. If anything doesn't work right, then see the section. Tell your OS to run the init script upon system startup and shutdown. If you are using a UNIX variant that has /etc/rc.conf or /etc/rc.conf.local (like BSD variants and Gentoo), you must set "hsqldb_enable" to "YES" in either of those files. (Just run cd /etc; ls rc.conf rc.conf.local to see if you have one of these files). For good UNIXes that use System V style init, you must set up hard links or soft links either manually or with management tools (such as chkconfig or insserv) or Gui's (like run level editors). This paragraph is for Mac OS X users only. If you followed the instructions above, your init script should reside at /Library/StartupItems/hsqldb/hsqldb. Now copy the file StartupParameters.plist from the directory src/org.hsqldb/sample of your HSQLDB distribution to the same directory as the init script. As long as these two files reside in /Library/StartupItems/hsqldb, your init script is active (for portability reasons, it doesn't check for a setting in /etc/hostconfig). You can run it as a Startup Item by running SystemStarter {start|stop|restart} Hsqldb Hsqldb is the service name. See the man page for SystemStarter. To disable the init script, wipe out the /Library/StartupItems/hsqldb directory. Hard to believe, but the Mac people tell me that during system shutdown the Startup Items don't run at all. Therefore, if you don't want your data corrupted, make sure to run "SystemStarter stop Hsqldb" before shutting down your Mac. Follow the examples in the config file to add additional classes to the server JVM's classpath and to execute additional classes in your JVM. (See the SERVER_ADDL_CLASSPATH and INVOC_ADDL_ARGS items).
                Troubleshooting the Init Script Do a ps to look for processes containing the string hsqldb, and try to connect to the database from any client. If the init script starts up your database successfully, but incorrectly reports that it has not, then your problem is with specification of urlid(s) or SqlTool setup. If your database really did not start, then skip to the next paragraph. Verify that the urlid(s) listed in the server.properties or webserver.properties are correct. and verify that you can run SqlTool as root to connect to the instances. (For the latter test, use the --rcfile switch if you are setting AUTH_FILE in the init script config file). If your database really is not starting, then verify that you can su to the database owner account and start the database. The command su USERNAME -c ... won't work on most UNIXes unless the target user has a real login shell. Therefore, if you try to tighten up security by disabling this user's login shell, you will break the init script. If these possibilities don't pan out, then debug the init script or seek help, as described below. To debug the init script, run it in verbose mode to see exactly what is happening (and perhaps manually run the steps that are suspect). To run an init script (in fact, any sh shell script) in verbose mode, use sh with the -x or -v switch, like sh -x path/to/hsqldb start See the man page for sh if you don't know the difference between -v and -x.

                Purpose Many questions repeatedly asked in Forums and mailing lists are answered in this guide. If you want to use HSQLDB with your application, you should read this guide.
                SQL Standard Support HSQLDB 1.8.0 supports the dialect of SQL defined by SQL standards 92, 99 and 2003. This means where a feature of the standard is supported, e.g. left outer join, the syntax is that specified by the standard text. Many features of SQL92 and 99 up to Advanced Level are supported and there is support for most of SQL 2003 Foundation and several optional features of this standard. However, certain features of the Standards are not supported so no claim is made for full support of any level of the standards. The SQL Syntax chapter of this guide lists all the keywords and syntax that is supported. When writing or converting existing SQL DDL (Data Definition Language) and DML (Data Manipulation Language) statements for HSQLDB, you should consult the supported syntax and modify the statements accordingly. Several words are reserved by the standard and cannot be used as table or column names. For example, the word POSITION is reserved as it is a function defined by the Standards with a similar role as String.indexOf() in Java. HSQLDB does not currently prevent you from using a reserved word if it does not support its use or can distinguish it. For example BEGIN is a reserved words that is not currently supported by HSQLDB and is allowed as a table or column name. You should avoid the use of such words as future versions of HSQLDB are likely to support the words and will reject your table definitions or queries. The full list of SQL reserved words is in the source of the org.hsqldb.Token class. HSQLDB also supports some keywords and expressions that are not part of the SQL standard as enhancements. Expressions such as SELECT TOP 5 FROM .., SELECT LIMIT 0 10 FROM ... or DROP TABLE mytable IF EXISTS are among such constructs. All keywords, can be used for database objects if they are double quoted.
                Constraints and Indexes
                Primary Key Constraints Before 1.7.0, a CONSTRAINT <name> PRIMARY KEY was translated internally to a unique index and, in addition, a hidden column was added to the table with an extra unique index. From 1.7.0 both single-column and multi-column PRIMARY KEY constraints are supported. They are supported by a unique index on the primary key column(s) specified and no extra hidden column is maintained for these indexes.
                Unique Constraints According to the SQL standards, a unique constraint on a single column means no two values are equal unless one of them is NULL. This means you can have one or more rows where the column value is NULL. A unique constraint on multiple columns (c1, c2, c3, ..) means that no two sets of values for the columns are equal unless at lease one of them is NULL. Each single column taken by itself can have repeat values. The following example satisfies a UNIQUE constraint on the two columns: Column values which satisfy a 2-column UNIQUE constraint 1, 2 2, 1 2, 2 NULL, 1 NULL, 1 1, NULL NULL, NULL NULL, NULL Since version 1.7.2 the behaviour of UNIQUE constraints and indexes with respect to NULL values has changed to conform to SQL standards. A row, in which the value for any of the UNIQUE constraint columns is NULL, can always be added to the table. So multiple rows can contain the same values for the UNIQUE columns if one of the values is NULL.
                Unique Indexes In 1.8.0, user defined UNIQUE indexes can still be declared but they are deprecated. You should use a UNIQUE constraint instead. CONSTRAINT <name> UNIQUE always creates internally a unique index on the columns, as with previous versions, so it has exactly the same effect as the deprecated UNIQUE index declaration.
                FOREIGN KEYS From version 1.7.0, HSQLDB features single and multiple column foreign keys. A foreign key can also be specified to reference a target table without naming the target column(s). In this case the primary key column(s) of the target table is used as the referenced column(s). Each pair of referencing and referenced columns in any foreign key should be of identical type. When a foreign key is declared, a unique constraint (or primary key) must exist on the referenced columns in the primary key table. A non-unique index is automatically created on the referencing columns. For example: CREATE TABLE child(c1 INTEGER, c2 VARCHAR, FOREIGN KEY (c1, c2) REFERENCES parent(p1, p2)); There must be a UNIQUE constraint on columns (p1,p2) in the table named "parent". A non-unique index is automatically created on columns (c1, c2) in the table named "child". Columns p1 and c1 must be of the same type (INTEGER). Columns p2 and c2 must be of the same type (VARCHAR).
                Indexes and Query Speed HSQLDB does not use indexes to improve sorting of query results. But indexes have a crucial role in improving query speed. If no index is used in a query on a single table, such as a DELETE query, then all the rows of the table must be examined. With an index on one of the columns that is in the WHERE clause, it is often possible to start directly from the first candidate row and reduce the number of rows that are examined. Indexes are even more important in joins between multiple tables. SELECT ... FROM t1 JOIN t2 ON t1.c1 = t2.c2 is performed by taking rows of t1 one by one and finding a matching row in t2. If there is no index index on t2.c2 then for each row of t1, all the rows of t2 must be checked. Whereas with an index, a matching row can be found in a fraction of the time. If the query also has a condition on t1, e.g., SELECT ... FROM t1 JOIN t2 ON t1.c1 = t2.c2 WHERE t1.c3 = 4 then an index on t1.c3 would eliminate the need for checking all the rows of t1 one by one, and will reduce query time to less than a millisecond per returned row. So if t1 and t2 each contain 10,000 rows, the query without indexes involves checking 100,000,000 row combinations. With an index on t2.c2, this is reduced to 10,000 row checks and index lookups. With the additional index on t2.c2, only about 4 rows are checked to get the first result row. Indexes are automatically created for primary key and unique columns. Otherwise you should define an index using the CREATE INDEX command. Note that in HSQLDB a unique index on multiple columns can be used internally as a non-unique index on the first column in the list. For example: CONSTRAINT name1 UNIQUE (c1, c2, c3); means there is the equivalent of CREATE INDEX name2 ON atable(c1);. So you do not need to specify an extra index if you require one on the first column of the list. In 1.8.0, a multi-column index will speed up queries that contain joins or values on ALL the columns. You need NOT declare additional individual indexes on those columns unless you use queries that search only on a subset of the columns. For example, rows of a table that has a PRIMARY KEY or UNIQUE constraint on three columns or simply an ordinary index on those columns can be found efficiently when values for all three columns are specified in the WHERE clause. For example, SELECT ... FROM t1 WHERE t1.c1 = 4 AND t1.c2 = 6 AND t1.c3 = 8 will use an index on t1(c1,c2,c3) if it exists. As a result of the improvements to multiple key indexes, the order of declared columns of the index or constraint has less affect on the speed of searches than before. If the column that contains more diverse values appears first, the searches will be slightly faster. A multi-column index will not speed up queries on the second or third column only. The first column must be specified in the JOIN .. ON or WHERE conditions. Query speed depends a lot on the order of the tables in the JOIN .. ON or FROM clauses. For example the second query below should be faster with large tables (provided there is an index on TB.COL3). The reason is that TB.COL3 can be evaluated very quickly if it applies to the first table (and there is an index on TB.COL3): (TB is a very large table with only a few rows where TB.COL3 = 4) SELECT * FROM TA JOIN TB ON TA.COL1 = TB.COL2 AND TB.COL3 = 4; SELECT * FROM TB JOIN TA ON TA.COL1 = TB.COL2 AND TB.COL3 = 4; The general rule is to put first the table that has a narrowing condition on one of its columns. 1.7.3 features automatic, on-the-fly indexes for views and subselects that are used in a query. An index is added to a view when it is joined to a table or another view.
                Where Condition or Join Using WHERE conditions to join tables is likely to reduce execution speed. For example the following query will generally be slow, even with indexes: SELECT ... FROM TA, TB, TC WHERE TC.COL3 = TA.COL1 AND TC.COL3=TB.COL2 AND TC.COL4 = 1 The query implies TA.COL1 = TB.COL2 but does not explicitly set this condition. If TA and TB each contain 100 rows, 10000 combinations will be joined with TC to apply the column conditions, even though there may be indexes on the joined columns. With the JOIN keyword, the TA.COL1 = TB.COL2 condition has to be explicit and will narrow down the combination of TA and TB rows before they are joined with TC, resulting in much faster execution with larger tables: SELECT ... FROM TA JOIN TB ON TA.COL1 = TB.COL2 JOIN TC ON TB.COL2 = TC.COL3 WHERE TC.COL4 = 1 The query can be speeded up a lot more if the order of tables in joins are changed, so that TC.COL1 = 1 is applied first and a smaller set of rows are joined together: SELECT ... FROM TC JOIN TB ON TC.COL3 = TB.COL2 JOIN TA ON TC.COL3 = TA.COL1 WHERE TC.COL4 = 1 In the above example the engine automatically applies TC.COL4 = 1 to TC and joins only the set of rows that satisfy this condition with other tables. Indexes on TC.COL4, TB.COL2 and TA.COL1 will be used if present and will speed up the query.
                Subqueries and Joins Using joins and setting up the order of tables for maximum performance applies to all areas. For example, the second query below should generally be much faster if there are indexes on TA.COL1 and TB.COL3: Query comparison SELECT ... FROM TA WHERE TA.COL1 = (SELECT MAX(TB.COL2) FROM TB WHERE TB.COL3 = 4) SELECT ... FROM (SELECT MAX(TB.COL2) C1 FROM TB WHERE TB.COL3 = 4) T2 JOIN TA ON TA.COL1 = T2.C1 The second query turns MAX(TB.COL2) into a single row table then joins it with TA. With an index on TA.COL1, this will be very fast. The first query will test each row in TA and evaluate MAX(TB.COL2) again and again.
                Types and Arithmetic Operations Table columns of all types supported by HSQLDB can be indexed and can feature in comparisons. Types can be explicitly converted using the CONVERT() library function, but in most cases they are converted automatically. It is recommended not to use indexes on LONGVARBINARY, LONGVARCHAR and OTHER columns, as these indexes will probably not be allowed in future versions. Previous versions of HSQLDB featured poor handling of arithmetic operations. For example, it was not possible to insert 10/2.5 into any DOUBLE or DECIMAL column. Since 1.7.0, full operations are possible with the following rules: TINYINT, SMALLINT, INTEGER, BIGINT, NUMERIC and DECIMAL (without a decimal point) are supported integral types and map to byte, short, int, long and BigDecimal in Java. The SQL type dictates the maximum and minimum values that can be held in a field of each type. For example the value range for TINYINT is -128 to +127, although the actual Java type used for handling TINYINT is java.lang.Integer. REAL, FLOAT, DOUBLE are all mapped to double in Java. DECIMAL and NUMERIC are mapped to java.math.BigDecimal and can have very large numbers of digits.
                Integral Types TINYINT, SMALLINT, INTEGER, BIGINT, NUMERIC and DECIMAL (without a decimal point) are fully interchangeable internally, and no data narrowing takes place. Depending on the types of the operands, the result of the operations is returned in a JDBC ResultSet in any of related Java types: Integer, Long or BigDecimal. The ResultSet.getXXXX() methods can be used to retrieve the values so long as the returned value can be represented by the resulting type. This type is deterministically based on the query, not on the actual rows returned. The type does not change when the same query that returned one row, returns many rows as a result of adding more data to the tables. If the SELECT statement refers to a simple column or function, then the return type is the type corresponding to the column or the return type of the function. For example: CREATE TABLE t(a INTEGER, b BIGINT); SELECT MAX(a), MAX(b) FROM t; would return a result set where the type of the first column is java.lang.Integer and the second column is java.lang.Long. However, SELECT MAX(a) + 1, MAX(b) + 1 FROM t; would return java.lang.Long and BigDecimal values, generated as a result of uniform type promotion for all the return values. There is no built-in limit on the size of intermediate integral values in expressions. As a result, you should check for the type of the ResultSet column and choose an appropriate getXXXX() method to retrieve it. Alternatively, you can use the getObject() method, then cast the result to java.lang.Number and use the intValue() or longValue() methods on the result. When the result of an expression is stored in a column of a database table, it has to fit in the target column, otherwise an error is returned. For example when 1234567890123456789012 / 12345687901234567890 is evaluated, the result can be stored in any integral type column, even a TINYINT column, as it is a small value.
                Other Numeric Types In SQL statements, numbers with a decimal point are treated as DECIMAL unless they are written with an exponent. Thus 0.2 is considered a DECIMAL value but 0.2E0 is considered a DOUBLE value. When PreparedStatement.setDouble() or setFloat() is used, the value is treated as a DOUBLE automatically. When a REAL, FLOAT or DOUBLE (all synonymous) is part of an expression, the type of the result is DOUBLE. Otherwise, when no DOUBLE value exists, if a DECIMAL or NUMERIC value is part an expression, the type of the result is DECIMAL. The result can be retrieved from a ResultSet in the required type so long as it can be represented. This means DECIMAL values can be converted to DOUBLE unless they are beyond the Double.MIN_VALUE - Double.MAX_VALUE range. Similar to integral values, when the result of an expression is stored in a table column, it has to fit in the target column, otherwise an error is returned. The distinction between DOUBLE and DECIMAL is important when a division takes place. When the terms are DECIMAL, the result is a value with a scale (number of digits to the right of the decimal point) equal to the larger of the scales of the two terms. With a DOUBLE term, the scale will reflect the actual result of the operation. For example, 10.0/8.0 (DECIMAL) equals 1.2 but 10.0E0/8.0E0 (DOUBLE) equals 1.25. Without division operations, DECIMAL values represent exact arithmetic; the resulting scale is the sum of the scales of the two terms when multiplication is performed. REAL, FLOAT and DOUBLE values are all stored in the database as java.lang.Double objects. Special values such as NaN and +-Infinity are also stored and supported. These values can be submitted to the database via JDBC PreparedStatement methods and are returned in ResultSet objects.
                Bit and Boolean Types Since 1.7.2, BIT is simply an alias for BOOLEAN. The primary representation of BOOLEAN column is 'true' or 'false' either as the boolean type or as strings when used from JDBC. This type of column can also be initialised using values of any numeric type. In this case 0 is translated to false and any other value such as 1 is translated to true. Since 1.7.3 the BOOLEAN type conforms to the SQL standards and supports the UNDEFINED state in addition to TRUE or FALSE. NULL values are treated as undefined. This improvement affects queries that contain NOT IN. See the test text file, TestSelfNot.txt, for examples of the queries.
                Storage and Handling of Java Objects Since version 1.7.2 this support has improved and any serializable JAVA Object can be inserted directly into a column of type OTHER using any variation of PreparedStatement.setObject() methods. For comparison purposes and in indexes, any two Java Objects are considered equal unless one of them is NULL. You cannot search for a specific object or perform a join on a column of type OTHER. Please note that HSQLDB is not an object-relational database. Java Objects can simply be stored internally and no operations should be performed on them other than assignment between columns of type OTHER or tests for NULL. Tests such as WHERE object1 = object2, or WHERE object1 = ? do not mean what you might expect, as any non-null object would satisfy such a tests. But WHERE object1 IS NOT NULL is perfectly acceptable. The engine does not return errors when normal column values are assigned to Java Object columns (for example assigning an INTEGER or STRING to such a column with an SQL statement such as UPDATE mytable SET objectcol = intcol WHERE ...) but this is highly likely to be disallowed in future. So please use columns of type OTHER only to store your objects and nothing else.
                Type Size, Precision and Scale Prior to 1.7.2, all table column type definitions with a column size, precision or scale qualifier were accepted and ignored. In 1.8.0, such qualifiers must conform to the SQL standards. For example INTEGER(8) is no longer acceptable. The qualifiers are still ignored unless you set a database property. SET PROPERTY "sql.enforce_strict_size" TRUE will enforce sizes for CHARACTER or VARCHAR columns and pad any strings when inserting or updating a CHARACTER column. The precision and scale qualifiers are also enforced for DECIMAL and NUMERIC types. TIMESTAMP can be used with a precision of 0 or 6 only. Casting a value to a qualified CHARACTER type will result in truncation or padding as you would expect. So a test such as CAST (mycol AS VARCHAR(2)) = 'xy' will find the values beginning with 'xy'. This is the equivalent of SUBSTRING(mycol FROM 1 FOR 2) = 'xy'.
                Sequences and Identity The SEQUENCE keyword was introduced in 1.7.2 with a subset of the SQL 200n standard syntax. Corresponding SQL 200n syntax for IDENTITY columns has also been introduced.
                Identity Auto-Increment Columns Each table can contain one auto-increment column, known as the IDENTITY column. An IDENTITY column is always treated as the primary key for the table (as a result, multi-column primary keys are not possible with an IDENTITY column present). Support has been added for CREATE TABLE <tablename>(<colname> IDENTITY, ...) as a shortcut. Since 1.7.2, the SQL standard syntax is used by default, which allows the initial value to be specified. The supported form is(<colname> INTEGER GENERATED BY DEFAULT AS IDENTITY(START WITH n, [INCREMENT BY m])PRIMARY KEY, ...). Support has also been added for BIGINT identity columns. As a result, an IDENTITY column is simply an INTEGER or BIGINT column with its default value generated by a sequence generator. When you add a new row to such a table using an INSERT INTO <tablename> ...; statement, you can use the NULL value for the IDENTITY column, which results in an auto-generated value for the column. The IDENTITY() function returns the last value inserted into any IDENTITY column by this connection. Use CALL IDENTITY(); as an SQL statement to retrieve this value. If you want to use the value for a field in a child table, you can use INSERT INTO <childtable> VALUES (...,IDENTITY(),...);. Both types of call to IDENTITY() must be made before any additional update or insert statements are issued on the database. The next IDENTITY value to be used can be set with the ALTER TABLE ALTER COLUMN <column name> RESTART WITH <new value>;
                Sequences The SQL 200n syntax and usage is different from what is supported by many existing database engines. Sequences are created with the CREATE SEQUENCE command and their current value can be modified at any time with ALTER SEQUENCE. The next value for a sequence is retrieved with the NEXT VALUE FOR <name> expression. This expression can be used for inserting and updating table rows. You can also use it in select statements. For example, if you want to number the returned rows of a SELECT in sequential order, you can use: Numbering returned rows of a SELECT in sequential order SELECT NEXT VALUE FOR mysequence, col1, col2 FROM mytable WHERE ... Please note that the semantics of sequences is not exactly the same as defined by SQL 200n. For example if you use the same sequence twice in the same row insert query, you will get two different values, not the same value as required by the standard. You can query the SYSTEM_SEQUENCES table for the next value that will be returned from any of the defined sequences. The SEQUENCE_NAME column contains the name and the NEXT_VALUE column contains the next value to be returned.
                Issues with Transactions HSQLDB supports transactions at the READ_UNCOMMITTED level, also known as level 0 transaction isolation. This means that during the lifetime of a transaction, other connections to the database can see the changes made to the data. Transaction support works well in general. Reported bugs concerning transactions being committed if the database is abruptly closed have been fixed. However, the following issues may be encountered only with multiple connections to a database using transactions: If two transactions modify the same row, no exception is raised when both transactions are committed. This can be avoided by designing your database in such a way that application data consistency does not depend on exclusive modification of data by one transaction. You can set a database property to cause an exception when this happens.SET PROPERTY "sql.tx_no_multi_rewrite" TRUEWhen an ALTER TABLE .. INSERT COLUMN or DROP COLUMN command results in changes to the table structure, the current session is committed. If an uncommitted transaction started by another connections has changed the data in the affected table, it may not be possible to roll it back after the ALTER TABLE command. This may also apply to ADD INDEX or ADD CONSTRAINT commands. It is recommended to use these ALTER commands only when it is known that other connections are not using transactions. After a CHECKPOINT command is issued, uncommitted transactions can be continued, committed, or rolled back. However, if the database is not subsequently closed properly with the SHUTDOWN command, any such transaction that still remains uncommitted at the time of shutdown, is part committed (to the state at CHECKPOINT) at the next startup. It is recommended to use the CHECKPOINT command either when no uncommitted transactions is in progress, or it is known that any such transaction is not likely to last for such a long time that an abnormal shutdown might affect its data.
                New Features and Changes In recent versions leading to 1.8.0 many enhancements were made for better SQL support. These are listed in the chapter, in and . Functions and expressions such as POSITION(), SUBSTRING(), NULLIF(), COALESCE(), CASE ... WHEN .. ELSE, ANY, ALL etc. are among them. Other enhancements may not be very obvious in the documentation but can result in changes of behaviour from previous versions. Most significant among these are handling of NULL values in joins (null columns are no longer joined) and OUTER joins (the results are now correct). You should test your applications with the new version to ensure they do not rely on past incorrect behaviour of the engine. The engine will continue to evolve in future versions towards full SQL standard support, so it is best not to rely on any non-standard feature of the current version.

                Purpose Many questions repeatedly asked in Forums and mailing lists are answered in this guide. If you want to use HSQLDB with your application, you should read this guide. This document covers system related issues. For issues related to SQL see the chapter.
                Connections The normal method of accessing an HSQLDB database is via the JDBC Connection interface. An introduction to different methods of providing database services and accessing them can be found in the chapter. Details and examples of how to connect via JDBC are provided in our JavaDoc for jdbcConnection. Version 1.7.2 introduced a uniform method of distinguishing between different types of connection, alongside new capabilities to provide access to multiple databases. The common driver identifier is jdbc:hsqldb: followed by a protocol identifier (mem: file: res: hsql: http: hsqls: https:) then followed by host and port identifiers in the case of servers, then followed by database identifier. Hsqldb URL Components Driver and Protocol Host and Port Database jdbc:hsqldb:mem: not available accounts Lowercase, single-word identifier creates the in-memory database when the first connection is made. Subsequent use of the same Connection URL connects to the existing DB. The old form for the URL, jdbc:hsqldb:. creates or connects to the same database as the new form for the URL, jdbc:hsqldb:mem:. jdbc:hsqldb:file: not available mydb /opt/db/accounts C:/data/mydb The file path specifies the database file. In the above examples the first one refers to a set of mydb.* files in the directory where the javacommand for running the application was issued. The second and third examples refer to absolute paths on the host machine. jdbc:hsqldb:res: not available /adirectory/dbname Database files can be loaded from one of the jars specified as part of the Java command the same way as resource files are accessed in Java programs. The /adirectory above stands for a directory in one of the jars. jdbc:hsqldb:hsql: jdbc:hsqldb:hsqls: jdbc:hsqldb:http: jdbc:hsqldb:https: //localhost //192.0.0.10:9500 //dbserver.somedomain.com /an_alias /enrollments /quickdb The host and port specify the IP address or host name of the server and an optional port number. The database to connect to is specified by an alias. This alias is a lowercase string defined in the server.properties file to refer to an actual database on the file system of the server or a transient, in-memory database on the server. The following example lines in server.properties or webserver.properties define the database aliases listed above and accessible to clients to refer to different file and in-memory databases. database.0=file:/opt/db/accounts dbname.0=an_alias database.1=file:/opt/db/mydb dbname.1=enrollments database.2=mem:adatabase dbname.2=quickdb The old form for the server URL, e.g., jdbc:hsqldb:hsql//localhost connects to the same database as the new form for the URL, jdbc:hsqldb:hsql//localhost/ where the alias is a zero length string. In the example below, the database files lists.* in the /home/dbmaster/ directory are associated with the empty alias: database.3=/home/dbmaster/lists dbname.3=
                Connection properties Each new JDBC Connection to a database can specify connection properties. The properties user and password are always required. In 1.8.0 the following optional properties can also be used. Connection properties are specified either by establishing the connection via the: DriverManager.getConnection (String url, Properties info); method call, or the property can be appended to the full Connection URL. Connection Properties get_column_name true column name in ResultSet This property is used for compatibility with other JDBC driver implementations. When true (the default), ResultSet.getColumnName(int c) returns the underlying column name When false, the above method returns the same value as ResultSet.getColumnLabel(int column) Example below: jdbc:hsqldb:hsql://localhost/enrollments;get_column_name=false When a ResultSet is used inside a user-defined stored procedure, the default, true, is always used for this property. ifexists false connect only if database already exists Has an effect only with mem: and file: database. When true, will not create a new database if one does not already exist for the URL. When false (the default), a new mem: or file: database will be created if it does not exist. Setting the property to true is useful when troubleshooting as no database is created if the URL is malformed. Example below: jdbc:hsqldb:file:enrollments;ifexists=true shutdown false shut down the database when the last connection is closed This mimics the behaviour of 1.7.1 and older versions. When the last connection to a database is closed, the database is automatically shut down. The property takes effect only when the first connection is made to the database. This means the connection that opens the database. It has no effect if used with subsequent, simultaneous connections. This command has two uses. One is for test suites, where connections to the database are made from one JVM context, immediately followed by another context. The other use is for applications where it is not easy to configure the environment to shutdown the database. Examples reported by users include web application servers, where the closing of the last connection conisides with the web app being shut down.
                In addition, when a connection to an in-process database creates a new database, or opens an existing database (i.e. it is the first connection made to the database by the application), all the user-defined database properties can be specified as URL properties. This can be used to specify properties to enforce more strict SQL adherence, or to change cache_scale or similar properties before the database files are created. However, for new databases, it is recommended to use the SET PROPERTY command for such settings.
                Properties Files HSQLDB relies on a set of properties files for different settings. Since 1.7.0 property naming has been streamlined and a number of new properties have been introduced. In all properties files, values are case-sensitive. All values apart from names of files or pages are required in lowercase (e.g. server.silent=FALSE will have no effect, but server.silent=false will work). The properties files and the settings stored in them are as follows: Hsqldb Server Properties Files File Name Location Function server.properties the directory where the command to run the Server class is issued settings for running HSQLDB as a database server communicating with the HSQL protocol webserver.properties the directory where the command to run the WebServer class is issued settings for running HSQLDB as a database server communicating with the HTTP protocol <dbname>.properties the directory where all the files for a database are located settings for each particular database
                Properties files for running the servers are not created automatically. You should create your own files that contain server.property=value pairs for each property. The properties file for each database is generated by the database engine. This file can be edited after closing the database. In 1.8.0, most of these properties can be changed via SQL commands.
                Server and Web Server Properties In both server.properties and webserver.properties files, supported values and their defaults are as follows: Property File Properties Value Default Description server.database.0 test the path and file name of the first database file to use server.dbname.0 "" lowercase server alias for the first database file server.urlid.0 NONE SqlTool urlid used by UNIX init script. (This property is not used if your are running Server/Webserver on a platform other than UNIX, or of you are not using our UNIX init script). server.silent true no extensive messages displayed on console server.trace false JDBC trace messages displayed on console
                In 1.8.0, each server can serve up to 10 different databases simultaneously. The server.database.0 property defines the filename / path whereas the server.dbname.0 defines the lowercase alias used by clients to connect to that database. The digit 0 is incremented for the second database and so on. Values for the server.database.{0-9} property can use the mem:, file: or res: prefixes and properties as discussed above under CONNECTIONS. For example, database.0=mem:temp;sql.enforce_strict_size=true; Values specific to server.properties are: Server Property File Properties Value Default Description server.port 9001 (normal) or 554 (if TLS encrypted) TCP/IP port used for talking to clients. All databases are served on the same port. server.no_system_exit true no System.exit() call when the database is closed
                Values specific to webserver.properties are: WebServer Property File Properties Value Default Description server.port 80 TCP/IP port used for talking to clients server.default_page index.html the default web page for server server.root ./ the location of served pages .<extension> ? multiple entries such as .html=text/html define the mime types of the static files served by the web server. See the source for WebServer.java for a list.
                All the above values can be specified on the command line to start the server by omitting the server. prefix.
                Starting a Server from your application If you want to start the server from within your application, as opposed to the command line or batch files, you should create an instance of Server or Web Server, then assign the properties in the form of a String and start the Server. An example of this can be found in the org.hsqldb.test.TestBase source. Upgrading: If you have existing custom properties files, change the values to the new naming convention. Note the use of digits at the end of server.database.n and server.dbname.n properties.
                Individual Database Properties Each database has its own <dbname>.properties file as part of a small group of files which also includes <dbname>.script and <dbname>.data. The properties files contain key/value pairs for some important settings. In version 1.8.0 a new SQL command allows most database properties to be modified as follows: SET PROPERTY "property_name" property_value Properties that can be modified via SET PROPERTY are indicated in the table below. Other properties are indicated as PROPERTIES FILE ONLY and can be modified only by editing the .properties file after a shutdown and before a restart. Only the user-defined values listed below should ever be modified. Changing any other value could result in unexpected malfunction in database operations. Most of these values have been introduced for the new features since 1.7.0: Database-specific Property File Properties Value Default Description readonly false whole database is read-only When true, the database cannot be modified in use. This setting can be changed to true if the database is to be opened from a CD. Prior to changing this setting, the database should be closed with the SHUTDOWN COMPACT command to ensure consistency and compactness of the data. (PROPERTIES FILE ONLY) but can be used as a connection property to open a normal database as readonly. hsqldb.files_readonly false database files will not be written to When true, data in MEMORY tables can be modified and new MEMORY tables can be added. However, these changes are not saved when the database is shutdown. CACHED and TEXT tables are always readonly when this setting is true. (PROPERTIES FILE ONLY) hsqldb.cache_file_scale 1 Set larger data file limits. Once set, the limit will go up to 8GB. This property can be set to 8 to increase the size limit of the .data file from 2GB to 8GB. To apply the change to an existing database, SHUTDOWN SCRIPT should be performed first, then the property=value line below should be added to the .properties file before reopening the database. hsqldb.cache_file_scale=8 The property can be set with the SQL command (as opposed to changing the value in the properties file) when the database has no CACHED tables (e.g. a new database). (SET PROPERTY) sql.enforce_size false trimming and padding string columns This property is no longer supported. Use sql.enforce_sctrict_size sql.enforce_strict_size false size enforcement and padding string columns Conforms to SQL standards for size and precision of data types. When true, all CHARACTER, VARCHAR, NUMERIC and DECIMAL values that are in a row affected by an INSERT INTO or UPDATE statement are checked against the size specified in the SQL table definition. An exception is thrown if the value is too long. Also all CHARACTER values that are shorter than the specified size are padded with spaces. TIMESTAMP(0) and TIMESTAMP(6) are also allowed in order to specify the subsecond resolution of the values. When false (default), stores the exact string that is inserted. (SET PROPERTY) sql.tx_no_multi_rewrite false transaction management In the default READ_UNCOMMITED mode, a transaction can write over rows inserted or updated by another uncommitted transaction. Setting this property to true will raise an exception when such a write is attempted (SET PROPERTY) hsqldb.cache_scale 14 memory cache exponent Indicates the maximum number of rows of cached tables that are held in memory, calculated as 3 *(2**value) (three multiplied by (two to the power value)). The default results in up to 3*16384 rows from all cached tables being held in memory at any time. The value can range between 8-18. (SET PROPERTY). If the value is set via SET PROPERTY then it becomes effective after the next database SHUTDOWN or CHECKPOINT. (SET PROPERTY) hsqldb.cache_size_scale 10 memory cache exponent Indicates the average size of each row in the memory cache used with cached tables, calculated as 2**value (two to the power value). This result value is multiplied by the maximum number of rows defined by hsqldb.cache_scale to form the maximum number of bytes for all the rows in memory cache. The default results in 1024 bytes per row. This default, combined with the default number of rows, results in approximately 50MB of the .data file to be stored in the memory cache. The value can range between 6-20. (SET PROPERTY). If the value is set via SET PROPERTY then it becomes effective after the next database SHUTDOWN or CHECKPOINT. (SET PROPERTY) hsqldb.log_size 200 size of log when checkpoint is performed The value is the size in megabytes that the .log file can reach before an automatic checkpoint occurs. A checkpoint and rewrites the .script file and clears the .log file. The value can be changed via the SET LOGSIZE nnn SQL command. runtime.gc_interval 0 forced garbage collection This setting forces garbage collection each time a set number of result set row or cache row objects are created. The default, "0" means no garbage collection is forced by the program. This should not be set when the database engine is acting as a server inside an exclusive JVM. The setting can be useful when the database is used in-process with the application with some Java Runtime Environments (JRE's). Some JRE's increase the size of the memory heap before doing any automatic garbage collection. This setting would prevent any unnecessary enlargement of the heap. Typical values for this setting would probably be between 10,000 to 100,000. (PROPERTIES FILE ONLY) hsqldb.nio_data_file true use of nio access methods for the .data file When HSQLDB is compiled and run in Java 1.4 or higher, setting this property to false will avoid the use of nio access methods, resulting in somewhat reduced speed. If the data file is larger than 256MB when it is first opened, nio access methods are not used. Also, if the file gets larger than the amount of available computer memory that needs to be allocated for nio access, non-nio access methods are used. (SET PROPERTY). If used before defining any CACHED table, it applies to the current session, otherwise it comes to effect after a SHUTDOWN and restart or CHECKPOINT. hsqldb.default_table_type memory type of table created with unqualified CREATE TABLE The CREATE TABLE command results in a MEMORY table by default. Setting the value "cached" for this property will result in a cached table by default. The qualified forms such as CREATE MEMORY TABLE or CREATE CACHED TABLE are not affected at all by this property. (SET PROPERTY) hsqldb.applog 0 application logging level The default level 0 indicates no logging. Level 1 results in events related to persistence to be logged, including any failures. The events are logged in a file ending with .app.log textdb.* 0 default properties for new text tables Properties that override the database engine defaults for newly created text tables. Settings in the text table SET <tablename> SOURCE <source string> command override both the engine defaults and the database properties defaults. Individual textdb.* properties are listed in the chapter. (SET PROPERTY)
                When connecting to an in-process database creates a new database, or opens an existing database (i.e. it is the first connection made to the database by the application), all the user-defined database properties listed in this section can be specified as URL properties. Upgrading: From 1.7.0, the location of the database files can no longer be overridden by paths defined in the properties file. All files belonging to a database should reside in the same directory. The property sql.compare_in_locale=true is no longer supported. If the line exists in a .properties file, it will switch the database to the collation for the current default. See the command. When HSQLDB is used in OpenOffice.org, some property values will have a different default. The properties and values are: hsqldb.default_table_type=cached hsqldb.cache_scale=13 hsqldb.log_size=10; hsqldb.nio_data_file=false sql.enforce_strict_size=true
                SQL Commands for Database Properties There are some database properties that are set with dedicated SQL commands beginning with SET. SQL command properties SET WRITE_DELAY {{TRUE | FALSE} | <seconds> | <milliseconds> MILLIS The default is TRUE and indicates that the changes to the database that have been logged are synched to the file system once every 20 seconds. FALSE indicates there is no delay and at each commit a file synch operation is performed. Numeric values from 0 can also be specified for the synch delay. The purpose of this command is to control the amount of data loss in case of a total system crash. A delay of 1 second means at most the data written to disk during the last second before the crash is lost. All data written prior to this has been synced and should be recoverable This setting should be specified on the basis of the reliability of the hardware used for running the database engine, the type of disk system used, the possibility of power failure etc. Also the nature of the data stored should be considered. In general, when the system is very reliable, the setting can be left to the default. If it is not very reliable, or the data is critical a setting of 1 or 2 seconds would suffice. Only in the worst case scenario or with the most critical data should a setting of 0 or FALSE be specified as this will slow the engine down to the speed at which the file synch operation can be performed by the disk subsystem. Values down to 10 millisconds can be specified by adding MILLIS to the command, but in practice a delay of 100 milliseconds provides 99.99999% reliability with an average one system crash per 6 days. SET LOG_SIZE <numeric value> The engine writes out a log of all the changes to the database as they occur. This log is synched to the disk based on the WRITE_DELAY property above. The log is never reused unless there is an abnormal termination, i.e. the database process is terminated without SHUTDOWN, or it was terminated using SHUTDOWN IMMEDIATELY. The default maximum size of the .log file is 200 MB. When the maximum size is reached, a CHECKPOINT operation is performed. This operation will save the other database files in a consistent state and delete the old log. A value of 0 indicates no limit for the .log file. SET CHECKPOINT DEFRAG <numeric value> When rows in CACHED tables are updated or deleted, the spaces are mostly reused. However, in time, some unused spaces are left in the .data file, especially when large tables are dropped or their structure is modified. A CHECKPOINT operation does not normally reclaim the empty spaces, whereas CHECKPOINT DEFRAG always does. This property determines when to perform a CHECKPOINT DEFRAG when a normal CHECKPOINT occurs (whether initiated by an administrator or when the size of the log exceeds its limit). The numeric value is the number of megabytes of recorded empty spaces in the .data file that would force a DEFRAG operation. Low values result in more frequent DEFRAG operations. A value of 0 indicates no automatic DEFRAG is performed. The default is 200 megabytes of lost space. SET REFERENTIAL INTEGRITY {TRUE | FALSE} This is TRUE by default. If bulk data needs to be loaded into the database, this property can be set FALSE for the duration of bulk load operation. This allows loading data for related tables in any order. The property should be set TRUE after bulk load. If the loaded data is not guaranteed to conform to the referential integrity constraints, SQL queries should be run after loading to identify and modify any non-conforming rows.

                Introduction HSQLDB can now act as a Database with OpenOffice.org. This document is written to help you connecting and running HSQLDB out of OpenOffice.org in a simple way. Without user-managment and only for your single-system. If you have problems read the other available documents, because I will not write them here again. If you need a real DB-System with user-management and different rights for different users, read the other documents. HSQLDB is included with OpenOffice.org 2.0 and is used by default. Please refer to standard OpenOffice.org 2.0 documentation on how to use HSQLDB with this version.
                Installing I assume you have a running OpenOffice.org (OOo) and a JavaRuntimeEnvironment. So place the hsqldb_*.zip file where you want on your disk and unpack it (I assume you have done this already).
                Setting up OpenOffice.org Start OOo with a text document and go to the Database-Explorer (simply by pressing F4). In the left frame you see a tree-view with all known databases in OOo. A right mouse-click opens a menu where you can manage your databases. So click on New Database and choose a name that you want to have inside OOo. I chose HSQLDB as name. As connection-type choose JDBC and then switch to the JDBC-tab. As Driver-Class insert org.hsqldb.jdbcDriver and as URL choose the following:
                On Windows You can specify a directory where HSQLDB should store the info and data. Something like jdbc:hsqldb:file:c:\javasrc\hsqldb-dev\databasename (where jdbc: is written by OOo). The string c:\javasrc\hsqldb-dev\databasename works only on windows, but you can write this down as linux-path like /javasrc/hsqldb-dev/databasename too. Then HSQLDB takes the c:\ drive as root. This means this works only on c:\ for you. The first is the directory-path and the databasename is the identifier for the database.
                On Linux Choose a path as said for windows like /opt/db/data As username take sa, this is the standard-administrator for HSQLDB. Now click the OK-Button
                Now OOo has to find your hsqldb.jar file. So go to options => security and insert the path to the .jar file. If you have problems, search the Online-help for JDBC. You then get help in your own language (this is generally quite better than my English, I think ;-) If you cannot write to your Tables, OOo thinks that you don't have permission to write to HSQLDB. Then we tell OOo to ignore the DriverPrivileges because on our single-user-system we do not need them. Because OOo is working on this, the next Step is only needed for systems without write - permission. So we go to http://dba.openoffice.org and look at the IgnoreDriverPrivileges.html file in the HowTo-section. You find here a macro-code. Open tools => macro in OOo to get the Basic-IDE. Here simple copy and paste the code and run the macro. You see a input-box where you only have to insert the name of your DB, in my example I have to insert HSQLDB, because I took this as name in OOo. Note that if you change your OOo-DB name, you have to run this macro again! Now we only have to stop and restart OOo. Be sure that you exit Quickstarter and all running processes too. On next OOo-Start you should have a running Database in OpenOffice.org.
