Use this option to force the Jdbc bundle not to be built even if the Jdbc libraries look like being present. --disable-mysql-bundle Disable creating the Mysql bundle. Use this option to force the Mysql bundle not to be built even if the Mysql libraries look like being present. --disable-sqllite-bundle Disable creating the Sqllite bundle. Use this option to force the Sqllite bundle not to be built even if the Sqllite libraries look like being present. --disable-postgres-bundle Disable creating the Postgres bundle. Use this option to force the Postgres bundle not to be built even if the Postgres libraries look like being present. Optional Packages: --with-PACKAGE[=ARG] use PACKAGE [ARG=yes] --without-PACKAGE do not use PACKAGE (same as --with-PACKAGE=no) --with-additional-include=flags Specifies additional include compiler flags to use. If configure can not find your database library headers, you may want to use this flag to help it find them. For example: --with-additional-include=-I/usr/local/include --with-additional-lib=flags Specifies additional library compiler flags to use. If configure can not find your database libraries, you may want to use this flag to help it find them. For example: --with-additional-lib=-L/usr/local/lib/mysql --with-postgres-dir=PATH Specifies the postgres installation dir; configure will add the appropriate additional include and lib flags. Useful when you installed postgres in some unusual place and want to help configure find it. For example: --with-postgres-dir=/usr/local/pgsql (which is equivalent to --with-additional-include=-L/usr/local/pgsql/include --with-additional-lib=-L/usr/local/pgsql/lib) --with-jre-architecture=value Specifies the CPU architecture to use for the JRE (only used when building the JDBC module). Example values are i386, amd64 and sparc. Some influential environment variables: CC C compiler command CFLAGS C compiler flags LDFLAGS linker flags, e.g. -L if you have libraries in a nonstandard directory LIBS libraries to pass to the linker, e.g. -l CPPFLAGS C/C++/Objective C preprocessor flags, e.g. -I if you have headers in a nonstandard directory CPP C preprocessor Use these variables to override the choices made by `configure' or to help it to find libraries and programs with nonstandard names/locations. _ACEOF ac_status=$? fi if test "$ac_init_help" = "recursive"; then # If there are subdirs, report their specific --help. for ac_dir in : $ac_subdirs_all; do test "x$ac_dir" = x: && continue test -d "$ac_dir" || { cd "$srcdir" && ac_pwd=`pwd` && srcdir=. && test -d "$ac_dir"; } || continue ac_builddir=. case "$ac_dir" in .) ac_dir_suffix= ac_top_builddir_sub=. ac_top_build_prefix= ;; *) ac_dir_suffix=/`$as_echo "$ac_dir" | sed 's|^\.[\\/]||'` # A ".." for each directory in $ac_dir_suffix. ac_top_builddir_sub=`$as_echo "$ac_dir_suffix" | sed 's|/[^\\/]*|/..|g;s|/||'` case $ac_top_builddir_sub in "") ac_top_builddir_sub=. ac_top_build_prefix= ;; *) ac_top_build_prefix=$ac_top_builddir_sub/ ;; esac ;; esac ac_abs_top_builddir=$ac_pwd ac_abs_builddir=$ac_pwd$ac_dir_suffix # for backward compatibility: ac_top_builddir=$ac_top_build_prefix case $srcdir in .) # We are building in place. ac_srcdir=. ac_top_srcdir=$ac_top_builddir_sub ac_abs_top_srcdir=$ac_pwd ;; [\\/]* | ?:[\\/]* ) # Absolute name. ac_srcdir=$srcdir$ac_dir_suffix; ac_top_srcdir=$srcdir ac_abs_top_srcdir=$srcdir ;; *) # Relative name. ac_srcdir=$ac_top_build_prefix$srcdir$ac_dir_suffix ac_top_srcdir=$ac_top_build_prefix$srcdir ac_abs_top_srcdir=$ac_pwd/$srcdir ;; esac ac_abs_srcdir=$ac_abs_top_srcdir$ac_dir_suffix cd "$ac_dir" || { ac_status=$?; continue; } # Check for guested configure. if test -f "$ac_srcdir/configure.gnu"; then echo && $SHELL "$ac_srcdir/configure.gnu" --help=recursive elif test -f "$ac_srcdir/configure"; then echo && $SHELL "$ac_srcdir/configure" --help=recursive else $as_echo "$as_me: WARNING: no configuration information is in $ac_dir" >&2 fi || ac_status=$? cd "$ac_pwd" || { ac_status=$?; break; } done fi test -n "$ac_init_help" && exit $ac_status if $ac_init_version; then cat <<\_ACEOF configure generated by GNU Autoconf 2.63 Copyright (C) 1992, 1993, 1994, 1995, 1996, 1998, 1999, 2000, 2001, 2002, 2003, 2004, 2005, 2006, 2007, 2008 Free Software Foundation, Inc.

Everyone is permitted to copy and distribute verbatim copies of this license document, but changing it is not allowed. This version of the GNU Lesser General Public License incorporates the terms and conditions of version 3 of the GNU General Public License, supplemented by the additional permissions listed below. 0. Additional Definitions. As used herein, "this License" refers to version 3 of the GNU Lesser General Public License, and the "GNU GPL" refers to version 3 of the GNU General Public License. "The Library" refers to a covered work governed by this License, other than an Application or a Combined Work as defined below. An "Application" is any work that makes use of an interface provided by the Library, but which is not otherwise based on the Library. Defining a subclass of a class defined by the Library is deemed a mode of using an interface provided by the Library. A "Combined Work" is a work produced by combining or linking an Application with the Library. The particular version of the Library with which the Combined Work was made is also called the "Linked Version". The "Minimal Corresponding Source" for a Combined Work means the Corresponding Source for the Combined Work, excluding any source code for portions of the Combined Work that, considered in isolation, are based on the Application, and not on the Linked Version. The "Corresponding Application Code" for a Combined Work means the object code and/or source code for the Application, including any data and utility programs needed for reproducing the Combined Work from the Application, but excluding the System Libraries of the Combined Work. 1. Exception to Section 3 of the GNU GPL. You may convey a covered work under sections 3 and 4 of this License without being bound by section 3 of the GNU GPL. 2. Conveying Modified Versions. If you modify a copy of the Library, and, in your modifications, a facility refers to a function or data to be supplied by an Application that uses the facility (other than as an argument passed when the facility is invoked), then you may convey a copy of the modified version: a) under this License, provided that you make a good faith effort to ensure that, in the event an Application does not supply the function or data, the facility still operates, and performs whatever part of its purpose remains meaningful, or b) under the GNU GPL, with none of the additional permissions of this License applicable to that copy. 3. Object Code Incorporating Material from Library Header Files. The object code form of an Application may incorporate material from a header file that is part of the Library. You may convey such object code under terms of your choice, provided that, if the incorporated material is not limited to numerical parameters, data structure layouts and accessors, or small macros, inline functions and templates (ten or fewer lines in length), you do both of the following: a) Give prominent notice with each copy of the object code that the Library is used in it and that the Library and its use are covered by this License. b) Accompany the object code with a copy of the GNU GPL and this license document. 4. Combined Works. You may convey a Combined Work under terms of your choice that, taken together, effectively do not restrict modification of the portions of the Library contained in the Combined Work and reverse engineering for debugging such modifications, if you also do each of the following: a) Give prominent notice with each copy of the Combined Work that the Library is used in it and that the Library and its use are covered by this License. b) Accompany the Combined Work with a copy of the GNU GPL and this license document. c) For a Combined Work that displays copyright notices during execution, include the copyright notice for the Library among these notices, as well as a reference directing the user to the copies of the GNU GPL and this license document. d) Do one of the following: 0) Convey the Minimal Corresponding Source under the terms of this License, and the Corresponding Application Code in a form suitable for, and under terms that permit, the user to recombine or relink the Application with a modified version of the Linked Version to produce a modified Combined Work, in the manner specified by section 6 of the GNU GPL for conveying Corresponding Source. 1) Use a suitable shared library mechanism for linking with the Library. A suitable mechanism is one that (a) uses at run time a copy of the Library already present on the user's computer system, and (b) will operate properly with a modified version of the Library that is interface-compatible with the Linked Version. e) Provide Installation Information, but only if you would otherwise be required to provide such information under section 6 of the GNU GPL, and only to the extent that such information is necessary to install and execute a modified version of the Combined Work produced by recombining or relinking the Application with a modified version of the Linked Version. (If you use option 4d0, the Installation Information must accompany the Minimal Corresponding Source and Corresponding Application Code. If you use option 4d1, you must provide the Installation Information in the manner specified by section 6 of the GNU GPL for conveying Corresponding Source.) 5. Combined Libraries. You may place library facilities that are a work based on the Library side by side in a single library together with other library facilities that are not Applications and are not covered by this License, and convey such a combined library under terms of your choice, if you do both of the following: a) Accompany the combined library with a copy of the same work based on the Library, uncombined with any other library facilities, conveyed under the terms of this License. b) Give prominent notice with the combined library that part of it is a work based on the Library, and explaining where to find the accompanying uncombined form of the same work. 6. Revised Versions of the GNU Lesser General Public License. The Free Software Foundation may publish revised and/or new versions of the GNU Lesser General Public License from time to time. Such new versions will be similar in spirit to the present version, but may differ in detail to address new problems or concerns. Each version is given a distinguishing version number. If the Library as you received it specifies that a certain numbered version of the GNU Lesser General Public License "or any later version" applies to it, you have the option of following the terms and conditions either of that published version or of any later version published by the Free Software Foundation. If the Library as you received it does not specify a version number of the GNU Lesser General Public License, you may choose any version of the GNU Lesser General Public License ever published by the Free Software Foundation. If the Library as you received it specifies that a proxy can decide whether future versions of the GNU Lesser General Public License shall apply, that proxy's public statement of acceptance of any version is permanent authorization for you to choose that version for the Library.

The SQLClient library is designed to provide a simple interface to SQL databases for GNUstep applications. It does not attempt the sort of abstraction provided by the much more sophisticated GDL2 library but rather allows applications to directly execute SQL queries and statements. SQLClient provides for the Objective-C programmer much the same thing that JDBC provides for the Java programmer (though SQLClient is a bit faster, easier to use, and easier to add new database backends for than JDBC). The major features of the SQLClient library are - * Simple API for executing queries and statements... a variable length sequence of comma separated strings and other objects (NSNumber, NSDate, NSData) are concatenated into a single SQL statement and executed. * Simple API for combining multiple SQL statements into a single transaction which can be used to minimise client-server interactions to get the best possible performance from your database. * Supports multiple sumultaneous named connections to a database server in a thread-safe manner. * Supports multiple simultaneous connections to different database servers with backend driver bundles loaded for different database engines. Clear, simple subclassing of the abstract base class to enable easy implementation of new backend bundles. * Configuration for all connections held in one place and referenced by connection name for ease of configuration control. Changes via NSUserDefaults can even allow reconfiguration of client instances within a running application. * Thread safe operation... The base class supports locking such that a single instance can be shared between multiple threads. What backend bundles are available? Current backend bundles are - * ECPG - a bundle using the embedded SQL interface for postgres. This is based on a similar code which has been in production use for over eighteen months, so it should be reliable. * Postgres - a bundle using the libpq native interface for postgres. This is the preferred backend as it allows 'SELECT FOR UPDATE', which the ECPG backend cannot support due to limitations in the postgres implementation of cursors. Now well tested efficient, and in use in large commercial systems. * MySQL - a bundle using the mysqlclient library for *recent* MySQL. I don't use MySQL... but the test program ran successfully with a vanilla install of the MySQL packages for recent Debian unstable. * SQLite - a bundle using the sqlite3 library which supports an SQL-like API for direct access to a database file (rather than acting as a client of a database server process). Not as functional as the other backends (doesn't support dates for instance), but good enough for many purposes and very 'lightweight'. See http://www.sqlite.org * Oracle - a bundle using embedded SQL for Oracle. Completely untested... may even need some work to compile... but this *is* based on code which was working about a year ago. No support for BLOBs yet. Where can you get it? How can you install it? The SQLClient library is currently available at or via CVS from the GNUstep CVS repository (See . Check out gnustep/dev-libs/SQLClient). To build this library you must have a basic GNUstep environment set up... * The gnustep-make package must have been built and installed. * The gnustep-base package must have been built and installed. * The Performance library (from the dev-libs area in GNUstep CVS) must have been built and installed. * If this environment is in place, all you should need to do is run 'make' to configure and build the library, 'make install' to install it. * Then you can run the test programs. * Your most likely problems are that the configure script may not detect the database libraries you want... Please figure out how to modify configure.ac so that it will detect the required headers and libraries on your system, and supply a patch.

The SQLClient library

What is the SQLClient library?

The SQLClient library is designed to provide a simple interface to SQL databases for GNUstep applications. It does not attempt the sort of abstraction provided by the much more sophisticated GDL2 library, but rather allows applications to directly execute SQL queries and statements.

The major features of the SQLClient library are -

  • Simple API for executing queries and statements... a variable length sequence of comma separated strings and other objects (NSNumber, NSDate, NSData) are concatenated into a single SQL statement and executed.
  • Support multiple sumultaneous named connections to a database server in a thread-safe manner.
  • Support multiple simultaneous connections to different database servers with backend driver bundles loaded for different database engines. Clear, simple subclassing of the abstract base class to enable easy implementation of new backend bundles.
  • Configuration for all connections held in one place and referenced by connection name for ease of configuration control. Changes via NSUserDefaults can even allow reconfiguration of client instances within a running application.
  • Thread safe operation... The base class supports locking such that a single instance can be shared between multiple threads.

What backend bundles are available?

Current backend bundles are -

  • ECPG - a bundle using the embedded SQL interface for postgres.
    This is based on a similar code which has been in production use for over eighteen months, so it should be reliable.
  • Postgres - a bundle using the libpq native interface for postgres.
    This is the preferred backend as it allows 'SELECT FOR UPDATE', which the ECPG backend cannot support due to limitations in the postgres implementation of cursors. The code is however not as well tested as the ECPG interface.
  • MySQL - a bundle using the mysqlclient library for *recent* MySQL.
    I don't use MySQL... but the test program ran successfully with a vanilla install of the MySQL packages for recent Debian unstable.
  • Oracle - a bundle using embedded SQL for Oracle.
    Completely untested... may even need some work to compile... but this *is* based on code which was working about a year ago.
    No support for BLOBs yet.

Where can you get it? How can you install it?

The SQLClient library is currently only available via CVS from the GNUstep CVS repository.
See <https://savannah.gnu.org/cvs/?group=gnustep>
You need to check out gnustep/dev-libs/SQLClient

To build this library you must have a basic GNUstep environment set up...

  • The gnustep-make package must have been built and installed.
  • The gnustep-base package must have been built and installed.
  • You must hace sourced the GNUstep.sh script (from gnustep-make) to set up environment variables needed for building this.
  • If this environment is in place, all you should need to do is run 'make' to configure and build the library, 'make install' to install it.
  • Then you can run the test programs.
  • Your most likely problems are that the configure script may not detect the database libraries you want... Please figure out how to modify configure.ac so that it will detect the required headers and libraries on your system, and supply na patch.
  • Once the library is installed, you can include the header file <SQLClient/SQLClient.h%gt; and link your programs with the SQLClient library to use it.

Bug reports, patches, and contributions (eg a backend bundle for a new database) should be entered on the GNUstep project page <http://savannah.gnu.org/projects/gnustep> and the bug reporting page <http://savannah.gnu.org/bugs/?group=gnustep>

Software documentation for the SQLClient class

SQLClient : NSObject

Declared in:
SQLClient.h

The SQLClient class encapsulates dynamic SQL access to relational database systems. A shared instance of the class is used for each database (as identified by the name of the database), and the number of simultanous database connections is managed too.

SQLClient is an abstract base class... when you create an instance of it, you are actually creating an instance of a concrete subclass whose implementation is loaded from a bundle.


Instance Variables for SQLClient Class

_client

@private NSString* _client;

Identifier within backend

_database

@private NSString* _database;

The configured database name/host

_debugging

@private unsigned int _debugging;

The current debugging level

_duration

@private NSTimeInterval _duration;

Description forthcoming.

_inTransaction

@private BOOL _inTransaction;

A flag indicating whether this instance is currently within a transaction. This variable must only be set by the -begin , -commit or -rollback methods.
Are we inside a transaction?

_lastOperation

@private NSDate* _lastOperation;

Timestamp of last operation.

Method summary

allClients 

+ (NSArray*) allClients;

Returns an array containing all the SQLClient instances.

clientWithConfiguration: name: 

+ (SQLClient*) clientWithConfiguration: (NSDictionary*)config name: (NSString*)reference;

Return an existing SQLClient instance (using +existingClient:) if possible, or creates one, initialises it using -initWithConfiguration:name: , and returns the new instance (autoreleased).
Returns nil on failure.

existingClient: 

+ (SQLClient*) existingClient: (NSString*)reference;

Return an existing SQLClient instance for the specified name if one exists, otherwise returns nil.

maxConnections 

+ (unsigned int) maxConnections;

Return the maximum number of simultaneous database connections permitted (set by +setMaxConnections: and defaults to 8)

purgeConnections: 

+ (void) purgeConnections: (NSDate*)since;

Use this method to reduce the number of database connections currently active so that it is less than the limit set by the +setMaxConnections: method. This mechanism is used internally by the class to ensure that, when it is about to open a new connection, the limit is not exceeded.

If since is not nil, then any connection which has not been used more recently than that date is disconnected anyway.
You can (and probably should) use this periodically to purge idle connections, but you can also pass a date in the future to close all connections.

setMaxConnections: 

+ (void) setMaxConnections: (unsigned int)c;

Set the maximum number of simultaneous database connections permitted (defaults to 8 and may not be set less than 1).

This value is used by the +purgeConnections: method to determine how many connections should be disconnected when it is called.

begin 

- (void) begin;

Start a transaction for this database client.
You must match this with either a -commit or a -rollback .

Normally, if you execute an SQL statement without using this method first, the autocommit feature is employed, and the statement takes effect immediately. Use of this method permits you to execute several statements in sequence, and only have them take effect (as a single operation) when you call the -commit method.

NB. You must not execute an SQL statement which would start a transaction directly... use only this method.

clientName 

- (NSString*) clientName;

Return the client name for this instance.
Normally this is useful only for debugging/reporting purposes, but if you are using multiple instances of this class in your application, and you are using embedded SQL, you will need to use this method to fetch the client/connection name and store its C-string representation in a variable 'connectionName' declared to the sql preprocessor, so you can then have statements of the form - 'exec sql at :connectionName...'.

commit 

- (void) commit;

Complete a transaction for this database client.
This must match an earlier -begin .

NB. You must not execute an SQL statement which would commit or rollback a transaction directly... use only this method or the -rollback method.

connect 

- (BOOL) connect;

If the connected instance variable is NO, this method calls -backendConnect to ensure that there is a connection to the database server established. Returns the result.
Performs any necessary locking for thread safety.

connected 

- (BOOL) connected;

Return a flag to say whether a connection to the database server is currently live. This is mostly useful for debug/reporting, but is used internally to keep track of active connections.

database 

- (NSString*) database;

Return the database name for this instance (or nil).

disconnect 

- (void) disconnect;

If the connected instance variable is YES, this method calls -backendDisconnect to ensure that the connection to the database server is dropped.
Performs any necessary locking for thread safety.

execute: ,...

- (void) execute: (NSString*)stmt,...;

Perform arbitrary operation which does not return any value.
This arguments to this method are a nil terminated list which are concatenated in the manner of the * -prepare:args: method.
Any string arguments are assumed to have been quoted appropriately already, but non-string arguments are automatically quoted using the -quote: method. 

   [db execute: @"UPDATE ", table, @" SET Name = ",
     myName, " WHERE ID = ", myId, nil];

execute: with: 

- (void) execute: (NSString*)stmt with: (NSDictionary*)values;

Takes the statement and substitutes in values from the dictionary where markup of the format {key} is found.
Passes the result to the -execute:,... method. 

   [db execute: @"UPDATE {Table} SET Name = {Name} WHERE ID = {ID}"
          with: values];
Any non-string values in the dictionary will be replaced by the results of the -quote: method.
The markup format may also be {key?default} where default is a string to be used if there is no value for the key in the dictionary.

initWithConfiguration: 

- (id) initWithConfiguration: (NSDictionary*)config;

Calls -initWithConfiguration:name: passing a nil reference name.

initWithConfiguration: name: 

- (id) initWithConfiguration: (NSDictionary*)config name: (NSString*)reference;

Initialise using the supplied configuration, or if that is nil, try to use values from NSUserDefaults (and automatically update when the defaults change).
Uses the reference name to determine configuration information... and if a nil name is supplied, defaults to the value of the SQLClientName as a user default string or 'Database' if no other name is provided.
If a SQLClient instance already exists with the name used for this instance, the receiver is deallocated and the existing instance is retained and returned... there may only ever be one instance for a particular reference name.

The config argument (or the SQLClientReferences user default) is a dictionary with names as keys and dictionaries as its values. Configuration entries from the dictionary corresponding to the database client are used if possible, general entries are used otherwise.
Database... is the name of the database to use, if it is missing then 'Database' may be used instead.
User... is the name of the database user to use, if it is missing then 'User' may be used instead.
Password... is the name of the database user password, if it is missing then 'Password' may be used instead.
ServerType... is the name of the backend server to be used... by convention the name of a bundle containing the interface to that backend. If this is missing then 'Postgres' is used.

isInTransaction 

- (BOOL) isInTransaction;

Return the state of the flag indicating whether the library thinks a transaction is in progress. This flag is normally maintained by -begin , -commit , and -rollback .

lastOperation 

- (NSDate*) lastOperation;

Returns the date/time stamp of the last database operation performed by the receiver, or nil if no operation has ever been done by it.
Simply connecting to or disconnecting from the databsse does not count as an operation.

name 

- (NSString*) name;

Return the database reference name for this instance (or nil).

password 

- (NSString*) password;

Return the database password for this instance (or nil).

query: ,...

- (NSMutableArray*) query: (NSString*)stmt,...;

Perform arbitrary query which returns values.

This method has at least one argument, the string starting the statement to be executed (which must have the prefix 'select ').

Additional arguments are a nil terminated list which also be strings, and these are appended to the statement.
Any string arguments are assumed to have been quoted appropriately already, but non-string arguments are automatically quoted using the -quote: method. 

   result = [db query: @"SELECT Name FROM ", table, nil];

Upon error, an exception is raised.

The query returns an array of records (each of which is represented by an SQLRecord object).

Each SQLRecord object contains one or more fields, in the order in which they occurred in the query. Fields may also be retrieved by name.

NULL field items are returned as NSNull objects.

Most other field items are returned as NSString objects.

Date and timestamp field items are returned as NSDate objects.

query: with: 

- (NSMutableArray*) query: (NSString*)stmt with: (NSDictionary*)values;

Takes the query statement and substitutes in values from the dictionary where markup of the format {key} is found.
Passes the result to the -query:,... method to execute. 

   result = [db query: @"SELECT Name FROM {Table} WHERE ID = {ID}"
                 with: values];
Any non-string values in the dictionary will be replaced by the results of the -quote: method.
The markup format may also be {key?default} where default is a string to be used if there is no value for the key in the dictionary.

quote: 

- (NSString*) quote: (id)obj;

Convert an object to a string suitable for use in an SQL query.
Normally the -execute:,... , and -query:,... methods will call this method automatically for everything apart from string objects.
Strings have to be handled specially, because they are used both for parts of the SQL command, and as values (where they need to be quoted). So where you need to pass a string value which needs quoting, you must call this method explicitly.
Subclasses may override this method to provide appropriate quoting for types of object which need database backend specific quoting conventions. However, the defalt implementation should be OK for most cases.
The base class implementation formats NSDate objects as
YYYY-MM-DD hh:mm:ss.mmm ?ZZZZ
NSData objects are not quoted... they must not appear in queries, and where used for insert/update operations, they need to be passed to the -backendExecute: method unchanged.
For a nil or NSNull object, we return NULL.
For a number, we simply convert directly to a string.
For a date, we convert to the text format used by the database, and add leading and trailing quotes.
For a data object, we don't quote... the other parts of the code need to know they have an NSData object and pass it on unchanged to the -backendExecute: method.
For any other type of data, we just produce a quoted string representation.

quoteCString: 

- (NSString*) quoteCString: (const char*)s;

Convert a 'C' string to a string suitable for use in an SQL query.

quoteChar: 

- (NSString*) quoteChar: (char)c;

Convert a single character to a string suitable for use in an SQL query.

quoteFloat: 

- (NSString*) quoteFloat: (float)f;

Convert a float to a string suitable for use in an SQL query.

quoteInteger: 

- (NSString*) quoteInteger: (int)i;

Convert an integer to a string suitable for use in an SQL query.

rollback 

- (void) rollback;

Revert a transaction for this database client.
This must match an earlier -begin .

NB. You must not execute an SQL statement which would commit or rollback a transaction directly... use only this method or the -rollback method.

setDatabase: 

- (void) setDatabase: (NSString*)s;

Set the database host/name for this object.
This is called automatically to configure the connection... you normally shouldn't need to call it yourself.

setName: 

- (void) setName: (NSString*)s;

Set the database reference name for this object. This is used to differentiate between multiple connections to the database.
This is called automatically to configure the connection... you normally shouldn't need to call it yourself.
NB. attempts to change the name of an instance to that of an existing instance are ignored.

setPassword: 

- (void) setPassword: (NSString*)s;

Set the database password for this object.
This is called automatically to configure the connection... you normally shouldn't need to call it yourself.

setUser: 

- (void) setUser: (NSString*)s;

Set the database user for this object.
This is called automatically to configure the connection... you normally shouldn't need to call it yourself.

simpleExecute: 

- (void) simpleExecute: (NSArray*)info;

Calls -backendExecute: in a safe manner.
Handles locking.
Maintains -lastOperation date.

simpleQuery: 

- (NSMutableArray*) simpleQuery: (NSString*)stmt;

Calls -backendQuery: in a safe manner.
Handles locking.
Maintains -lastOperation date.

user 

- (NSString*) user;

Return the database user for this instance (or nil).

Software documentation for the SQLRecord class

Software documentation for the SQLClient(Logging) category

SQLClient(Logging)

Declared in:
SQLClient.h

This category porovides basic methods for logging debug information.

Method summary

debugging 

+ (unsigned int) debugging;

Return the class-wide debugging level, which is inherited by all newly created instances.

durationLogging 

+ (NSTimeInterval) durationLogging;

Return the class-wide duration logging threshold, which is inherited by all newly created instances.

setDebugging: 

+ (void) setDebugging: (unsigned int)level;

Set the debugging level to be inherited by all new instances.

setDurationLogging: 

+ (void) setDurationLogging: (NSTimeInterval)threshold;

Set the duration logging threshold to be inherited by all new instances.

debug: ,...

- (void) debug: (NSString*)fmt,...;

The default implementation calls NSLogv to log a debug message.
Override this in a category to provide more sophisticated logging.

debugging 

- (unsigned int) debugging;

Return the current debugging level.

durationLogging 

- (NSTimeInterval) durationLogging;

Returns the threshold above which queries and statements taking a long time to execute are logged. A negative value (default) indicates that this logging is disabled. A value of zero means that all statements are logged.

setDebugging: 

- (void) setDebugging: (unsigned int)level;

Set the debugging level of this instance... overrides the default level inherited from the class.

setDurationLogging: 

- (void) setDurationLogging: (NSTimeInterval)threshold;

Set a threshold above which queries and statements taking a long time to execute are logged. A negative value (default) disables this logging. A value of zero logs all statements.

Software documentation for the SQLClient(Subclass) category

SQLClient(Subclass)

Declared in:
SQLClient.h

This category contains the methods which a subclass must override to provide a working instance, and helper methods for the backend implementations.
Application programmers should not call the backend methods directly.

When subclassing to produce a backend driver bundle, please be aware that the subclass must NOT introduce additional instance variables. Instead the extra instance variable is provided for use as a pointer to subclass specific data.

Method summary

backendConnect 

- (BOOL) backendConnect;
Subclasses should override this method.

Attempts to establish a connection to the database server.
Returns a flag to indicate whether the connection has been established.
If a connection was already established, returns YES and does nothing.
You should not need to use this method normally, as it is called for you automatically when necessary.

Subclasses must implement this method to establish a connection to the database server process (and initialise the extra instance variable if necessary), setting the connected instance variable to indicate the state of the object.

This method must call +purgeConnections: to ensure that there is a free slot for the new connection.

Application code must not call this method directly, it is for internal use only. The -connect method calls this method if the connected instance variable is NO.

backendDisconnect 

- (void) backendDisconnect;
Subclasses should override this method.

Disconnect from the database unless already disconnected.

This method is called automatically when the receiver is deallocated or reconfigured, and may also be called automatically when there are too many database connections active.

If the receiver is an instance of a subclass which uses the extra instance variable, it must clear that variable in the -backendDisconnect method, because a reconfiguration may cause the class of the receiver to change.

This method must set the connected instance variable to NO.

Application code must not call this method directly, it is for internal use only. The -disconnect method calls this method if the connected instance variable is YES.

backendExecute: 

- (void) backendExecute: (NSArray*)info;
Subclasses should override this method.

Perform arbitrary operation which does not return any value.
This method has a single argument, an array containing the string representing the statement to be executed as its first object, and an optional sequence of data objects following it. 

   [db backendExecute: [NSArray arrayWithObject:
     @"UPDATE MyTable SET Name = 'The name' WHERE ID = 123"]];

The backend implementation is required to perform the SQL statement using the supplied NSData objects at the points in the statement marked by the ''' sequence. The marker saequences are inserted into the statement at an earlier stage by the -execute:,... and -execute:with: methods.

This method should lock the instance using the lock instance variable for the duration of the operation, and unlock it afterwards.

NB. callers (other than the -begin , -commit , and -rollback methods) should not pass any statement to this method which would cause a transaction to begin or end.

Application code must not call this method directly, it is for internal use only.

backendQuery: 

- (NSMutableArray*) backendQuery: (NSString*)stmt;
Subclasses should override this method.

Perform arbitrary query which returns values. 

   result = [db backendQuery: @"SELECT Name FROM Table"];

Upon error, an exception is raised.

The query returns an array of records (each of which is represented by an SQLRecord object).

Each SQLRecord object contains one or more fields, in the order in which they occurred in the query. Fields may also be retrieved by name.

NULL field items are returned as NSNull objects.

This method should lock the instance using the lock instance variable for the duration of the operation, and unlock it afterwards.

Application code must not call this method directly, it is for internal use only.

copyEscapedBLOB: into: 

- (unsigned) copyEscapedBLOB: (NSData*)blob into: (void*)buf;
Subclasses should override this method.

This method is only for the use of the -insertBLOBs:intoStatement:length:withMarker:length:giving: method.
Subclasses which need to insert binary data into a statement must implement this method to copy the escaped data into place and return the number of bytes actually copied.

insertBLOBs: intoStatement: length: withMarker: length: giving: 

- (const void*) insertBLOBs: (NSArray*)blobs intoStatement: (const void*)statement length: (unsigned)sLength withMarker: (const void*)marker length: (unsigned)mLength giving: (unsigned*)result;

This method is a convenience method provided for subclasses which need to insert escaped binary data into an SQL statement before sending the statement to a backend server process. This method makes use of the -copyEscapedBLOB:into: and -lengthOfEscapedBLOB: methods, which must be implemented by the subclass.

The blobs array is an array containing the original SQL statement string (unused by this method) followed by the data items to be inserted.

The statement and sLength arguments specify the datastream to be copied and into which the BLOBs are to be inserted.

The marker and mLength arguments specify the sequence of marker bytes in the statement which indicate a position for insertion of a n escaped BLOB.

The method returns either the original statement or a copy containing the escaped BLOBs. The length of the returned data is stored in result.

lengthOfEscapedBLOB: 

- (unsigned) lengthOfEscapedBLOB: (NSData*)blob;
Subclasses should override this method.

This method is only for the use of the -insertBLOBs:intoStatement:length:withMarker:length:giving: method.
Subclasses which need to insert binary data into a statement must implement this method to return the length of the escaped bytestream which will be inserted.

SQLClient documentation The SQLClient library
What is the SQLClient library?

The SQLClient library is designed to provide a simple interface to SQL databases for GNUstep applications. It does not attempt the sort of abstraction provided by the much more sophisticated GDL2 library, but rather allows applications to directly execute SQL queries and statements.

SQLClient provides for the Objective-C programmer much the same thing that JDBC provides for the Java programmer (though SQLClient is a bit faster, easier to use, and easier to add new database backends for than JDBC).

The major features of the SQLClient library are -

Simple API for executing queries and statements ... a variable length sequence of comma separated strings and other objects (NSNumber, NSDate, NSData) are concatenated into a single SQL statement and executed. Simple API ([SQLTransaction])for combining multiple SQL statements into a single transaction which can be used to minimise client-server interactions to get the best possible performance from your database. Supports multiple sumultaneous named connections to a database server in a thread-safe manner.
 Supports multiple simultaneous connections to different database servers with backend driver bundles loaded for different database engines. Clear, simple subclassing of the abstract base class to enable easy implementation of new backend bundles. Configuration for all connections held in one place and referenced by connection name for ease of configuration control. Changes via NSUserDefaults can even allow reconfiguration of client instances within a running application. Thread safe operation ... The base class supports locking such that a single instance can be shared between multiple threads. Support for standalone web applications ... eg to allow data to be added to the database by people posting web forms to the application. Supports notification of connection to and disconnection from the database server.
What backend bundles are available?

Current backend bundles are -

ECPG - a bundle using the embedded SQL interface for postgres.
This is based on a similar code which was in production use for over eighteen months, so it should be reliable, but inefficient. Postgres - a bundle using the libpq native interface for postgres.
This is the preferred backend as it allows 'SELECT FOR UPDATE', which the ECPG backend cannot support due to limitations in the postgres implementation of cursors. The code is now well tested and known to be efficient. MySQL - a bundle using the mysqlclient library for *recent* MySQL.
I don't use MySQL ... but the test program ran successfully with a vanilla install of the MySQL packages for recent Debian unstable. SQLite - a bundle using the sqlite3 library which supports an SQL-like API for direct access to a database file (rather than acting as a client of a database server process).
Not as functional as the other backends (doesn't support dates for instance), but good enough for many purposes and very 'lightweight'. See http://www.sqlite.org Oracle - a bundle using embedded SQL for Oracle.
Completely untested ... may even need some work to compile ... but this *is* based on code which was working about a year ago.
No support for BLOBs yet.
Where can you get it? How can you install it?

The SQLClient library is currently only available via CVS from the GNUstep CVS repository.
See <https://savannah.gnu.org/cvs/?group=gnustep>
You need to check out gnustep/dev-libs/SQLClient

To build this library you must have a basic GNUstep environment set up ...

The gnustep-make package must have been built and installed. The gnustep-base package must have been built and installed. The Performance library (from the dev-libs area in GNUstep CVS) must have been built and installed. If this environment is in place, all you should need to do is run 'make' to configure and build the library, 'make install' to install it. Then you can run the test programs. Your most likely problems are that the configure script may not detect the database libraries you want ... Please figure out how to modify configure.ac so that it will detect the required headers and libraries on your system, and supply na patch. Once the library is installed, you can include the header file <SQLClient/SQLClient.h%gt; and link your programs with the SQLClient library to use it.

Bug reports, patches, and contributions (eg a backend bundle for a new database) should be entered on the GNUstep project page <http://savannah.gnu.org/projects/gnustep> and the bug reporting page <http://savannah.gnu.org/bugs/?group=gnustep>

Improve quoting of strings to be a bit more efficient and to remove nul characters. 2005-05-09 Richard Frith-Macdonald * WebServer.[hm]: Add method to encode a form from a dictionary into a data object ... convenience for where form data is needed. 2005-03-02 Richard Frith-Macdonald * WebServer.[hm]: Add support for basic http authentication either via username/password pairs in property list or in database table. * SQLClient.[hm]: Add methods to query database with local caching of results, for use on systems needing high performance, where database query (and/or database client-server comms) overheads are important. 2005-02-25 Adam Fedor * Version 1.1.0: * GNUmakefile: Add version. * README: Add ftp location. Sat Feb 19 04:20:00 2004 Richard Frith-Macdonald * Makefile: Build two versions of each bundle with different library linkage for systems where dybnamic linker symbol visibility differs. * SQLClient.m: Try alternative bundle versions.

Sat Dec 18 06:00:00 2004 Richard Frith-Macdonald * WebServer.m: Fix bug in substitution of nil values into templates. Add new method to vend static pages. Wed Dec 15 13:10:00 2004 Richard Frith-Macdonald * MySQL.m, Postgres.m, ECPG.pgm: Do NSLog() logging of field information only when debug level is greater than 1. Fri Dec 10 10:50:00 2004 Richard Frith-Macdonald * GNUmakefile: Remove unnecessary libraries from link commands for bundles. On Darwin, specifying these leads to multiply defined symbols when an executable attempts to load the bundle. Fri Nov 19 14:40:00 2004 Richard Frith-Macdonald * WebServer.m: parse basic authentication infor and set it in extra headers in request. * WebServerBundles.m: support handling of paths longer than the ones set for each bundle. Tue Nov 11 14:48:05 2004 Nicola Pero * GNUmakefile (BUNDLE_INSTALL_DIR): install bundles in GNUSTEP_INSTALLATION_DIR, not GNUSTEP_LOCAL_ROOT. Tue Nov 09 10:20:00 2004 Richard Frith-Macdonald * SQLClient.hm: add ([-append:]) method to merge transactions. Thu Oct 28 08:45:00 2004 Richard Frith-Macdonald * WebServer.m: Don't generate alert about connection with empty request if we have lready handled a request and reset. Tue Oct 26 16:50:00 2004 Richard Frith-Macdonald * SQLClient.m: debug and duration logging should be turned off by default ... a different value crept in somehow. Sat Oct 9 14:29:35 2004 Nicola Pero * SQLClient.m ([SQLClient -simpleExecute:]): Fixed logging durations and statements in transactions. Thu Oct 08 10:30:00 2004 Richard Frith-Macdonald * SQLClient.[hm]: Add ([-quotef:,...]) to perform efficient quoting of a string produced using printf style format and arguments. Thu Oct 07 10:30:00 2004 Richard Frith-Macdonald * SQLClient.[hm]: Optimise timing operations somewhat. Wed Oct 06 15:04:23 2004 Nicola Pero * WebServer.h: Fixed typo in parameter name. Wed Oct 06 13:10:00 2004 Richard Frith-Macdonald * SQLClient.[hm]: Allow a database transaction to already have been begun when [SQLTransactiuon-execute] is called, so we can have queries in the same database transaction as a list of statements. Wed Oct 06 06:15:00 2004 Richard Frith-Macdonald * SQLClient.[hm]: Make the rollback opoeration a safe no-op if there is no transaction in progress. * Postgres.m: Improve exception text by reporting the offending SQL statement(s). Fri Sep 17 16:55:00 2004 Richard Frith-Macdonald * SQLClient.[hm]: When reporting the duration of a commit or rollback, report text of all the statements in the transaction. Fri Aug 28 09:30:00 2004 Richard Frith-Macdonald * WebServer.[hm]: Add support for limiting maximum number of incoming sessions permitted from mone host. Tue Aug 24 14:30:00 2004 Richard Frith-Macdonald * WebServer.[hm]: Add support for HTTP/1.1 persistent connections.

Sat Aug 07 14:25:00 2004 Richard Frith-Macdonald * WebServer.m: Add session timeouts to kill off idle sessions. Tue Jul 27 17:30:00 2004 Richard Frith-Macdonald * configure.ac: Give more help when postgres is not found. * configure: regenerate Mon Jul 26 09:50:00 2004 Richard Frith-Macdonald * SQLClient.h: Add -transaction method and SQLTransaction class * SQLClient.m: Implement -transaction method and SQLTransaction class to provide a simple convenient mechanism for executing a sequence of statements as a single transaction. Thu Jul 15 09:40:00 2004 Richard Frith-Macdonald * WebServer.m: ([_didRead:]) more informative logging upon reading an unexpected end-of-file Wed Jul 14 12:07:00 2004 Richard Frith-Macdonald * configure.ac: Check for PQfformat in libpq, if it is not there but the library is there, warn that it is too old. Thu Jul 02 17:40:00 2004 Richard Frith-Macdonald * WebServer.m: Add control over character encoding used to interpret form data. Thu Jul 02 13:25:00 2004 Richard Frith-Macdonald * WebServer.m: Fix error response when an exception occurs. Thu Jul 01 18:00:00 2004 Richard Frith-Macdonald * WebServer.m: Make ([setPort:secure:]) return a status. * WebServerBundles.m: Check that web server is able to start. * WebServer.h: ditto Wed Jun 30 05:40:00 2004 Richard Frith-Macdonald * GNUmakefile: Use ./obj as location for library to link, for initial case where we link the bundles before installing the library. * WebServer.m: Add casts to prevent compiler warning. * Postgres.m: Commented out NSLog() left over from debugging. Tue Jun 29 18:10:00 2004 Richard Frith-Macdonald * SQLClient.m: Fix code for retrieving reference name ... look in the config dictionary first, and in user defaults if not found there. * SQLClient.h: Document change. * GNUmakefile: Link bundles with the library to ensure that they find the SQLRecord class when loaded. Mon Jun 28 12:55:00 2004 Richard Frith-Macdonald * WebServer.h: New file. * WebServer.m: New file. * WebServerBundles.m: New file. * SQLClient.h: Mention WebServer. * GNUmakefile: Build WebServer classes. Added framework to make it easy to use SQLClient to produce standalone http/https applications, such as accepting POST'ed records for addition to a database. Fri May 07 09:15:00 2004 Richard Frith-Macdonald Add methods to log duration of any statements over a certain limit. Tidy instance variables ... prefix mprivate ones with underscore. Install header! Thu Apr 29 15:20:00 2004 Richard Frith-Macdonald * SQLClient.h: Fix URLs in documentation as suggested by Adam. * SQLClient.html: regenerate Mon Apr 26 16:20:00 2004 Richard Frith-Macdonald Initial checkin of library.
