Preamble ======== The GNU General Public License is a free, copyleft license for software and other kinds of works. The licenses for most software and other practical works are designed to take away your freedom to share and change the works. By contrast, the GNU General Public License is intended to guarantee your freedom to share and change all versions of a program--to make sure it remains free software for all its users. We, the Free Software Foundation, use the GNU General Public License for most of our software; it applies also to any other work released this way by its authors. You can apply it to your programs, too. When we speak of free software, we are referring to freedom, not price. Our General Public Licenses are designed to make sure that you have the freedom to distribute copies of free software (and charge for them if you wish), that you receive source code or can get it if you want it, that you can change the software or use pieces of it in new free programs, and that you know you can do these things. To protect your rights, we need to prevent others from denying you these rights or asking you to surrender the rights. Therefore, you have certain responsibilities if you distribute copies of the software, or if you modify it: responsibilities to respect the freedom of others. For example, if you distribute copies of such a program, whether gratis or for a fee, you must pass on to the recipients the same freedoms that you received. You must make sure that they, too, receive or can get the source code. And you must show them these terms so they know their rights. Developers that use the GNU GPL protect your rights with two steps: (1) assert copyright on the software, and (2) offer you this License giving you legal permission to copy, distribute and/or modify it. For the developers' and authors' protection, the GPL clearly explains that there is no warranty for this free software. For both users' and authors' sake, the GPL requires that modified versions be marked as changed, so that their problems will not be attributed erroneously to authors of previous versions. Some devices are designed to deny users access to install or run modified versions of the software inside them, although the manufacturer can do so. This is fundamentally incompatible with the aim of protecting users' freedom to change the software. The systematic pattern of such abuse occurs in the area of products for individuals to use, which is precisely where it is most unacceptable. Therefore, we have designed this version of the GPL to prohibit the practice for those products. If such problems arise substantially in other domains, we stand ready to extend this provision to those domains in future versions of the GPL, as needed to protect the freedom of users. Finally, every program is threatened constantly by software patents. States should not allow patents to restrict development and use of software on general-purpose computers, but in those that do, we wish to avoid the special danger that patents applied to a free program could make it effectively proprietary. To prevent this, the GPL assures that patents cannot be used to render the program non-free. The precise terms and conditions for copying, distribution and modification follow. TERMS AND CONDITIONS ==================== 0. Definitions. "This License" refers to version 3 of the GNU General Public License. "Copyright" also means copyright-like laws that apply to other kinds of works, such as semiconductor masks. "The Program" refers to any copyrightable work licensed under this License. Each licensee is addressed as "you". "Licensees" and "recipients" may be individuals or organizations. To "modify" a work means to copy from or adapt all or part of the work in a fashion requiring copyright permission, other than the making of an exact copy. The resulting work is called a "modified version" of the earlier work or a work "based on" the earlier work. A "covered work" means either the unmodified Program or a work based on the Program. To "propagate" a work means to do anything with it that, without permission, would make you directly or secondarily liable for infringement under applicable copyright law, except executing it on a computer or modifying a private copy. Propagation includes copying, distribution (with or without modification), making available to the public, and in some countries other activities as well. To "convey" a work means any kind of propagation that enables other parties to make or receive copies. Mere interaction with a user through a computer network, with no transfer of a copy, is not conveying. An interactive user interface displays "Appropriate Legal Notices" to the extent that it includes a convenient and prominently visible feature that (1) displays an appropriate copyright notice, and (2) tells the user that there is no warranty for the work (except to the extent that warranties are provided), that licensees may convey the work under this License, and how to view a copy of this License. If the interface presents a list of user commands or options, such as a menu, a prominent item in the list meets this criterion. 1. Source Code. The "source code" for a work means the preferred form of the work for making modifications to it. "Object code" means any non-source form of a work. A "Standard Interface" means an interface that either is an official standard defined by a recognized standards body, or, in the case of interfaces specified for a particular programming language, one that is widely used among developers working in that language. The "System Libraries" of an executable work include anything, other than the work as a whole, that (a) is included in the normal form of packaging a Major Component, but which is not part of that Major Component, and (b) serves only to enable use of the work with that Major Component, or to implement a Standard Interface for which an implementation is available to the public in source code form. A "Major Component", in this context, means a major essential component (kernel, window system, and so on) of the specific operating system (if any) on which the executable work runs, or a compiler used to produce the work, or an object code interpreter used to run it. The "Corresponding Source" for a work in object code form means all the source code needed to generate, install, and (for an executable work) run the object code and to modify the work, including scripts to control those activities. However, it does not include the work's System Libraries, or general-purpose tools or generally available free programs which are used unmodified in performing those activities but which are not part of the work. For example, Corresponding Source includes interface definition files associated with source files for the work, and the source code for shared libraries and dynamically linked subprograms that the work is specifically designed to require, such as by intimate data communication or control flow between those subprograms and other parts of the work. The Corresponding Source need not include anything that users can regenerate automatically from other parts of the Corresponding Source. The Corresponding Source for a work in source code form is that same work. 2. Basic Permissions. All rights granted under this License are granted for the term of copyright on the Program, and are irrevocable provided the stated conditions are met. This License explicitly affirms your unlimited permission to run the unmodified Program. The output from running a covered work is covered by this License only if the output, given its content, constitutes a covered work. This License acknowledges your rights of fair use or other equivalent, as provided by copyright law. You may make, run and propagate covered works that you do not convey, without conditions so long as your license otherwise remains in force. You may convey covered works to others for the sole purpose of having them make modifications exclusively for you, or provide you with facilities for running those works, provided that you comply with the terms of this License in conveying all material for which you do not control copyright. Those thus making or running the covered works for you must do so exclusively on your behalf, under your direction and control, on terms that prohibit them from making any copies of your copyrighted material outside their relationship with you. Conveying under any other circumstances is permitted solely under the conditions stated below. Sublicensing is not allowed; section 10 makes it unnecessary. 3. Protecting Users' Legal Rights From Anti-Circumvention Law. No covered work shall be deemed part of an effective technological measure under any applicable law fulfilling obligations under article 11 of the WIPO copyright treaty adopted on 20 December 1996, or similar laws prohibiting or restricting circumvention of such measures. When you convey a covered work, you waive any legal power to forbid circumvention of technological measures to the extent such circumvention is effected by exercising rights under this License with respect to the covered work, and you disclaim any intention to limit operation or modification of the work as a means of enforcing, against the work's users, your or third parties' legal rights to forbid circumvention of technological measures. 4. Conveying Verbatim Copies. You may convey verbatim copies of the Program's source code as you receive it, in any medium, provided that you conspicuously and appropriately publish on each copy an appropriate copyright notice; keep intact all notices stating that this License and any non-permissive terms added in accord with section 7 apply to the code; keep intact all notices of the absence of any warranty; and give all recipients a copy of this License along with the Program. You may charge any price or no price for each copy that you convey, and you may offer support or warranty protection for a fee. 5. Conveying Modified Source Versions. You may convey a work based on the Program, or the modifications to produce it from the Program, in the form of source code under the terms of section 4, provided that you also meet all of these conditions: a. The work must carry prominent notices stating that you modified it, and giving a relevant date. b. The work must carry prominent notices stating that it is released under this License and any conditions added under section 7. This requirement modifies the requirement in section 4 to "keep intact all notices". c. You must license the entire work, as a whole, under this License to anyone who comes into possession of a copy. This License will therefore apply, along with any applicable section 7 additional terms, to the whole of the work, and all its parts, regardless of how they are packaged. This License gives no permission to license the work in any other way, but it does not invalidate such permission if you have separately received it. d. If the work has interactive user interfaces, each must display Appropriate Legal Notices; however, if the Program has interactive interfaces that do not display Appropriate Legal Notices, your work need not make them do so. A compilation of a covered work with other separate and independent works, which are not by their nature extensions of the covered work, and which are not combined with it such as to form a larger program, in or on a volume of a storage or distribution medium, is called an "aggregate" if the compilation and its resulting copyright are not used to limit the access or legal rights of the compilation's users beyond what the individual works permit. Inclusion of a covered work in an aggregate does not cause this License to apply to the other parts of the aggregate. 6. Conveying Non-Source Forms. You may convey a covered work in object code form under the terms of sections 4 and 5, provided that you also convey the machine-readable Corresponding Source under the terms of this License, in one of these ways: a. Convey the object code in, or embodied in, a physical product (including a physical distribution medium), accompanied by the Corresponding Source fixed on a durable physical medium customarily used for software interchange. b. Convey the object code in, or embodied in, a physical product (including a physical distribution medium), accompanied by a written offer, valid for at least three years and valid for as long as you offer spare parts or customer support for that product model, to give anyone who possesses the object code either (1) a copy of the Corresponding Source for all the software in the product that is covered by this License, on a durable physical medium customarily used for software interchange, for a price no more than your reasonable cost of physically performing this conveying of source, or (2) access to copy the Corresponding Source from a network server at no charge. c. Convey individual copies of the object code with a copy of the written offer to provide the Corresponding Source. This alternative is allowed only occasionally and noncommercially, and only if you received the object code with such an offer, in accord with subsection 6b. d. Convey the object code by offering access from a designated place (gratis or for a charge), and offer equivalent access to the Corresponding Source in the same way through the same place at no further charge. You need not require recipients to copy the Corresponding Source along with the object code. If the place to copy the object code is a network server, the Corresponding Source may be on a different server (operated by you or a third party) that supports equivalent copying facilities, provided you maintain clear directions next to the object code saying where to find the Corresponding Source. Regardless of what server hosts the Corresponding Source, you remain obligated to ensure that it is available for as long as needed to satisfy these requirements. e. Convey the object code using peer-to-peer transmission, provided you inform other peers where the object code and Corresponding Source of the work are being offered to the general public at no charge under subsection 6d. A separable portion of the object code, whose source code is excluded from the Corresponding Source as a System Library, need not be included in conveying the object code work. A "User Product" is either (1) a "consumer product", which means any tangible personal property which is normally used for personal, family, or household purposes, or (2) anything designed or sold for incorporation into a dwelling. In determining whether a product is a consumer product, doubtful cases shall be resolved in favor of coverage. For a particular product received by a particular user, "normally used" refers to a typical or common use of that class of product, regardless of the status of the particular user or of the way in which the particular user actually uses, or expects or is expected to use, the product. A product is a consumer product regardless of whether the product has substantial commercial, industrial or non-consumer uses, unless such uses represent the only significant mode of use of the product. "Installation Information" for a User Product means any methods, procedures, authorization keys, or other information required to install and execute modified versions of a covered work in that User Product from a modified version of its Corresponding Source. The information must suffice to ensure that the continued functioning of the modified object code is in no case prevented or interfered with solely because modification has been made. If you convey an object code work under this section in, or with, or specifically for use in, a User Product, and the conveying occurs as part of a transaction in which the right of possession and use of the User Product is transferred to the recipient in perpetuity or for a fixed term (regardless of how the transaction is characterized), the Corresponding Source conveyed under this section must be accompanied by the Installation Information. But this requirement does not apply if neither you nor any third party retains the ability to install modified object code on the User Product (for example, the work has been installed in ROM). The requirement to provide Installation Information does not include a requirement to continue to provide support service, warranty, or updates for a work that has been modified or installed by the recipient, or for the User Product in which it has been modified or installed. Access to a network may be denied when the modification itself materially and adversely affects the operation of the network or violates the rules and protocols for communication across the network. Corresponding Source conveyed, and Installation Information provided, in accord with this section must be in a format that is publicly documented (and with an implementation available to the public in source code form), and must require no special password or key for unpacking, reading or copying. 7. Additional Terms. "Additional permissions" are terms that supplement the terms of this License by making exceptions from one or more of its conditions. Additional permissions that are applicable to the entire Program shall be treated as though they were included in this License, to the extent that they are valid under applicable law. If additional permissions apply only to part of the Program, that part may be used separately under those permissions, but the entire Program remains governed by this License without regard to the additional permissions. When you convey a copy of a covered work, you may at your option remove any additional permissions from that copy, or from any part of it. (Additional permissions may be written to require their own removal in certain cases when you modify the work.) You may place additional permissions on material, added by you to a covered work, for which you have or can give appropriate copyright permission. Notwithstanding any other provision of this License, for material you add to a covered work, you may (if authorized by the copyright holders of that material) supplement the terms of this License with terms: a. Disclaiming warranty or limiting liability differently from the terms of sections 15 and 16 of this License; or b. Requiring preservation of specified reasonable legal notices or author attributions in that material or in the Appropriate Legal Notices displayed by works containing it; or c. Prohibiting misrepresentation of the origin of that material, or requiring that modified versions of such material be marked in reasonable ways as different from the original version; or d. Limiting the use for publicity purposes of names of licensors or authors of the material; or e. Declining to grant rights under trademark law for use of some trade names, trademarks, or service marks; or f. Requiring indemnification of licensors and authors of that material by anyone who conveys the material (or modified versions of it) with contractual assumptions of liability to the recipient, for any liability that these contractual assumptions directly impose on those licensors and authors. All other non-permissive additional terms are considered "further restrictions" within the meaning of section 10. If the Program as you received it, or any part of it, contains a notice stating that it is governed by this License along with a term that is a further restriction, you may remove that term. If a license document contains a further restriction but permits relicensing or conveying under this License, you may add to a covered work material governed by the terms of that license document, provided that the further restriction does not survive such relicensing or conveying. If you add terms to a covered work in accord with this section, you must place, in the relevant source files, a statement of the additional terms that apply to those files, or a notice indicating where to find the applicable terms. Additional terms, permissive or non-permissive, may be stated in the form of a separately written license, or stated as exceptions; the above requirements apply either way. 8. Termination. You may not propagate or modify a covered work except as expressly provided under this License. Any attempt otherwise to propagate or modify it is void, and will automatically terminate your rights under this License (including any patent licenses granted under the third paragraph of section 11). However, if you cease all violation of this License, then your license from a particular copyright holder is reinstated (a) provisionally, unless and until the copyright holder explicitly and finally terminates your license, and (b) permanently, if the copyright holder fails to notify you of the violation by some reasonable means prior to 60 days after the cessation. Moreover, your license from a particular copyright holder is reinstated permanently if the copyright holder notifies you of the violation by some reasonable means, this is the first time you have received notice of violation of this License (for any work) from that copyright holder, and you cure the violation prior to 30 days after your receipt of the notice. Termination of your rights under this section does not terminate the licenses of parties who have received copies or rights from you under this License. If your rights have been terminated and not permanently reinstated, you do not qualify to receive new licenses for the same material under section 10. 9. Acceptance Not Required for Having Copies. You are not required to accept this License in order to receive or run a copy of the Program. Ancillary propagation of a covered work occurring solely as a consequence of using peer-to-peer transmission to receive a copy likewise does not require acceptance. However, nothing other than this License grants you permission to propagate or modify any covered work. These actions infringe copyright if you do not accept this License. Therefore, by modifying or propagating a covered work, you indicate your acceptance of this License to do so. 10. Automatic Licensing of Downstream Recipients. Each time you convey a covered work, the recipient automatically receives a license from the original licensors, to run, modify and propagate that work, subject to this License. You are not responsible for enforcing compliance by third parties with this License. An "entity transaction" is a transaction transferring control of an organization, or substantially all assets of one, or subdividing an organization, or merging organizations. If propagation of a covered work results from an entity transaction, each party to that transaction who receives a copy of the work also receives whatever licenses to the work the party's predecessor in interest had or could give under the previous paragraph, plus a right to possession of the Corresponding Source of the work from the predecessor in interest, if the predecessor has it or can get it with reasonable efforts. You may not impose any further restrictions on the exercise of the rights granted or affirmed under this License. For example, you may not impose a license fee, royalty, or other charge for exercise of rights granted under this License, and you may not initiate litigation (including a cross-claim or counterclaim in a lawsuit) alleging that any patent claim is infringed by making, using, selling, offering for sale, or importing the Program or any portion of it. 11. Patents. A "contributor" is a copyright holder who authorizes use under this License of the Program or a work on which the Program is based. The work thus licensed is called the contributor's "contributor version". A contributor's "essential patent claims" are all patent claims owned or controlled by the contributor, whether already acquired or hereafter acquired, that would be infringed by some manner, permitted by this License, of making, using, or selling its contributor version, but do not include claims that would be infringed only as a consequence of further modification of the contributor version. For purposes of this definition, "control" includes the right to grant patent sublicenses in a manner consistent with the requirements of this License. Each contributor grants you a non-exclusive, worldwide, royalty-free patent license under the contributor's essential patent claims, to make, use, sell, offer for sale, import and otherwise run, modify and propagate the contents of its contributor version. In the following three paragraphs, a "patent license" is any express agreement or commitment, however denominated, not to enforce a patent (such as an express permission to practice a patent or covenant not to sue for patent infringement). To "grant" such a patent license to a party means to make such an agreement or commitment not to enforce a patent against the party. If you convey a covered work, knowingly relying on a patent license, and the Corresponding Source of the work is not available for anyone to copy, free of charge and under the terms of this License, through a publicly available network server or other readily accessible means, then you must either (1) cause the Corresponding Source to be so available, or (2) arrange to deprive yourself of the benefit of the patent license for this particular work, or (3) arrange, in a manner consistent with the requirements of this License, to extend the patent license to downstream recipients. "Knowingly relying" means you have actual knowledge that, but for the patent license, your conveying the covered work in a country, or your recipient's use of the covered work in a country, would infringe one or more identifiable patents in that country that you have reason to believe are valid. If, pursuant to or in connection with a single transaction or arrangement, you convey, or propagate by procuring conveyance of, a covered work, and grant a patent license to some of the parties receiving the covered work authorizing them to use, propagate, modify or convey a specific copy of the covered work, then the patent license you grant is automatically extended to all recipients of the covered work and works based on it. A patent license is "discriminatory" if it does not include within the scope of its coverage, prohibits the exercise of, or is conditioned on the non-exercise of one or more of the rights that are specifically granted under this License. You may not convey a covered work if you are a party to an arrangement with a third party that is in the business of distributing software, under which you make payment to the third party based on the extent of your activity of conveying the work, and under which the third party grants, to any of the parties who would receive the covered work from you, a discriminatory patent license (a) in connection with copies of the covered work conveyed by you (or copies made from those copies), or (b) primarily for and in connection with specific products or compilations that contain the covered work, unless you entered into that arrangement, or that patent license was granted, prior to 28 March 2007. Nothing in this License shall be construed as excluding or limiting any implied license or other defenses to infringement that may otherwise be available to you under applicable patent law. 12. No Surrender of Others' Freedom. If conditions are imposed on you (whether by court order, agreement or otherwise) that contradict the conditions of this License, they do not excuse you from the conditions of this License. If you cannot convey a covered work so as to satisfy simultaneously your obligations under this License and any other pertinent obligations, then as a consequence you may not convey it at all. For example, if you agree to terms that obligate you to collect a royalty for further conveying from those to whom you convey the Program, the only way you could satisfy both those terms and this License would be to refrain entirely from conveying the Program. 13. Use with the GNU Affero General Public License. Notwithstanding any other provision of this License, you have permission to link or combine any covered work with a work licensed under version 3 of the GNU Affero General Public License into a single combined work, and to convey the resulting work. The terms of this License will continue to apply to the part which is the covered work, but the special requirements of the GNU Affero General Public License, section 13, concerning interaction through a network will apply to the combination as such. 14. Revised Versions of this License. The Free Software Foundation may publish revised and/or new versions of the GNU 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 Program specifies that a certain numbered version of the GNU General Public License "or any later version" applies to it, you have the option of following the terms and conditions either of that numbered version or of any later version published by the Free Software Foundation. If the Program does not specify a version number of the GNU General Public License, you may choose any version ever published by the Free Software Foundation. If the Program specifies that a proxy can decide which future versions of the GNU General Public License can be used, that proxy's public statement of acceptance of a version permanently authorizes you to choose that version for the Program. Later license versions may give you additional or different permissions. However, no additional obligations are imposed on any author or copyright holder as a result of your choosing to follow a later version. 15. Disclaimer of Warranty. THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION. 16. Limitation of Liability. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES. 17. Interpretation of Sections 15 and 16. If the disclaimer of warranty and limitation of liability provided above cannot be given local legal effect according to their terms, reviewing courts shall apply local law that most closely approximates an absolute waiver of all civil liability in connection with the Program, unless a warranty or assumption of liability accompanies a copy of the Program in return for a fee. END OF TERMS AND CONDITIONS =========================== How to Apply These Terms to Your New Programs ============================================= If you develop a new program, and you want it to be of the greatest possible use to the public, the best way to achieve this is to make it free software which everyone can redistribute and change under these terms. To do so, attach the following notices to the program. It is safest to attach them to the start of each source file to most effectively state the exclusion of warranty; and each file should have at least the "copyright" line and a pointer to where the full notice is found. ONE LINE TO GIVE THE PROGRAM'S NAME AND A BRIEF IDEA OF WHAT IT DOES. Copyright (C) YEAR NAME OF AUTHOR This program is free software: you can redistribute it and/or modify it under the terms of the GNU General Public License as published by the Free Software Foundation, either version 3 of the License, or (at your option) any later version. This program is distributed in the hope that it will be useful, but WITHOUT ANY WARRANTY; without even the implied warranty of MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the GNU General Public License for more details. You should have received a copy of the GNU General Public License along with this program. If not, see `http://www.gnu.org/licenses/'. Also add information on how to contact you by electronic and paper mail. If the program does terminal interaction, make it output a short notice like this when it starts in an interactive mode: PROGRAM Copyright (C) YEAR NAME OF AUTHOR This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'. This is free software, and you are welcome to redistribute it under certain conditions; type `show c' for details. The hypothetical commands `show w' and `show c' should show the appropriate parts of the General Public License. Of course, your program's commands might be different; for a GUI interface, you would use an "about box". You should also get your employer (if you work as a programmer) or school, if any, to sign a "copyright disclaimer" for the program, if necessary. For more information on this, and how to apply and follow the GNU GPL, see `http://www.gnu.org/licenses/'. The GNU General Public License does not permit incorporating your program into proprietary programs. If your program is a subroutine library, you may consider it more useful to permit linking proprietary applications with the library. If this is what you want to do, use the GNU Lesser General Public License instead of this License. But first, please read `http://www.gnu.org/philosophy/why-not-lgpl.html'. database-2.4.4/PaxHeaders.8241/INDEX0000644000000000000000000000013213444726064013544 xustar0030 mtime=1553181748.464224151 30 atime=1553181748.464224151 30 ctime=1553181803.415144792 database-2.4.4/INDEX0000644000175000017500000000047313444726064014021 0ustar00olafolaf00000000000000database >> Database.

4.1 Converting Octave variables to bytea

Loadable Function: var2bytea (value, …)

Save input values in uint8 arrays in Octaves binary save format.

This function returns as many output variables as input variables are given.

The function can be used to prepare storage of Octave variable values as binary strings in a database, if the variables types have no corresponding SQL type. Each variable type which can be correctly saved and loaded with Octaves save and load functions is acceptable. The variable value can be restored with the function bytea2var.

Note that the inputs are not variable names, but values. No variable names are saved. Loading the uint8 array with load (possibly after dumping it to a file) will not work.

Example: to convert the first and third column of a cell-array c, [c{:, [1, 3]}] = var2bytea (c{:, [1, 3]}); can be used.

See also: bytea2var.

4 Storing arbitrary Octave types in a database

If Octave variable types have corresponding SQL types ( see SQL data types , also consider the links there to types specific for database implementations), the variables can directly be stored in a database. If not, the variables can be converted to representations of the SQL type bytea and then stored. This way of storing is possible for all Octave types which can be correctly saved and loaded with Octaves save and load functions.

• var2bytea:  Converting Octave variables to bytea.
• bytea2var:  Converting bytea back to Octave variables.

2 Introduction and package concept

To enable scripting of SQL access, particularly combinations of SQL commands with temporary local storage or local processing of data, for almost each SQL data type a corresponding representation of the data in Octave is defined. This includes the SQL array types and user-defined SQL composite types (row types) of arbitrary nesting depth. Octave variables containing these corresponding representations are created by the package if data is received from a database by a select query, and correspondingly are used for sending data to the database. This data exchange is lossless if the database backend allows it (which is the case for Postgresql).

The representations of SQL types in Octave are the ’naturally’ corresponding Octave types, if possible. They can also be created directly in Octave and sent to a database.

The package keeps a notion of all SQL types available in a database. This information is automatically retrieved after connecting. If the user creates new types with SQL commands, a package function for refreshing the packages information on types must be called for the type to be available within the same session. The same function should be called if the session continues after deletion of types.

The package provides functions for issuing SQL commands whose text is provided by the user. The command text can contain placeholders for data. The data, corresponding to these placeholders, can be passed to the function in separate arguments.

In queries, not only data is returned, but also information on data type and column names.

General documentation for the database package for Octave

The info version of this document is accessible, after package installation, from the Octave commandline with database_doc().

This documentation applies to version 2.4.4 of the database package.

The database package enables accessing SQL databases from Octave. Differences between database implementations will inevitably cause some of this packages functions to be specific for a certain implementation. Currently, however, this package only supports the Postgresql database. Later additions might support further databases, and possibly some general functions (with only very basic functionality), which can be used for all backends, will also be provided.

This documentation currently describes the concepts of SQL access in ’database’ and the details for Postgresql. Familiarity with SQL and the database implementation (Postgresql) is assumed.

• Installation:  Installation hints.
• Concept:  Introduction and package concept.
• SQL data types:  Representation in Octave of types defined by SQL.

An octave_pq_connection object contains information on a connection and will be internally altered by the packages functions even though it is only passed as an argument, i.e. Octaves ’pass by value’ semantics are not adhered to in this case.

settings can be set by setdbopts (copied from Octaves optimset) and can contain (defaults depend on Postgresql): host (hostname), hostaddr (numeric host address), port (port to connect to), dbname (database to connect to), user (user name to connect as), password, connect_timeout, options (command-line options to send to the server at run-time, see Postgresql documentation), sslmode (disable, allow, prefer, require, verify-ca, or verify-full; see Postgresql documentation of SSL support), sslcert (file name of client SSL certificate), sslkey (location of secret key for client certificate, file name or external OpenSSL engine (colon-separated engine name and an engine-specific key identifier)), sslrootcert (file name of root SSL certificate), sslcrl (file name of SSL certificate revocation list), krbsrvname (kerberos service name), service (service name in pq_service.conf to use for additional parameters).

All these settings are passed to the server as they are, so it may be better to consult the postgresql documentation for them, e.g. the documentation of the PQconnectdb function in libpq.

7.3.2 Updating type information

Loadable Function: pq_update_types (connection)

Updates information on existing postgresql types for connection. Use this before pq_exec_params if types were created or dropped while the connection was already established or if the schema search path changed. A newly created connection will automatically retrieve this information at connection time.

7.3.1 Issuing SQL commands

Function File: pq_exec_params (connection, command)
Loadable Function: pq_exec_params (connection, command, params)
Loadable Function: pq_exec_params (connection, command, settings)
Loadable Function: pq_exec_params (connection, command, params, settings)

Sends the string command, which must contain a single SQL command, over the connection connection. Parameters in command can be replaced by $1, $2, etc and their values given in the one-dimensional cell-array params. Parameters of composite type sent this way must have their type defined in the database. For typeconversions, the package maintains a notion of defined types, which should be refreshed with pq_update_types if types are defined or dropped after establishing the connection, or if the schema search path changes. settings is a structure of settings, it can be created by setdbopts.

Settings currently understood by pq_exec_params:

param_types

One-dimensional cell-array with type specifications for parameters in params. If present, must have the same length as params. Entries may be empty if no specification is necessary (see below). Type specifications are strings corresponding to the entries returned by SELECT typname FROM pg_type WHERE typarray != 0 OR typtype = 'c';, optionally having [] appended (without space) to indicate an array. Type specifications can be schema-qualified, otherwise they refer to the visible type with that name.

copy_in_path, copy_out_path

Path to files at the client side for copy from stdin and copy to stdout, respectively.

copy_in_from_variable

Logical scalar, default false. If true, copy from stdin uses data from an Octave variable instead of from a file.

copy_in_data

2-dimensional cell-array with columns of suitable type (see below) – will be used instead of a file as data for copy from stdin if copy_in_from_variable is true.

copy_in_types

If some columns in copy_in_data need a type specification (see below), copy_in_types has to be set to a cell-array with type specifications, with an entry (possibly empty) for each column.

copy_in_with_oids

If you want to copy in with oids when using data from an Octave variable, the first column of the data must contain the OIDs and copy_in_with_oids has to be set to true (default false); with oids should be specified together with copy from stdin in the command, otherwise Postgresql will ignore the copied oids.

There is no way to copy to stdout into an Octave variable, but a select command can be used for this purpose.

copy from stdin from an Octave variable is only supported in binary mode, so this has to be specified in the SQL command.

The output depends on the type of command.

  • queries (commands potentially returning data): The output will be a structure with fields data (containing a cell array with the data, columns correspond to returned database columns, rows correspond to returned tuples), columns (containing the column headers), and types (a structure-vector with the postgresql data types of the columns, subfields name (string with typename), is_array (boolean), is_composite (boolean), is_enum (boolean), and elements (if is_composite == true, structure-vector of element types, containing fields corresponding to those of types)).
  • copy commands: Nothing is returned (this may change in the future).
  • other commands: The output will be the number of affected rows in the database.

See also: pq_update_types, pq_conninfo.

Type mapping

For the mapping of currently implemented Postgresql types to Octave types, see Postgresql data types.

7.1 Representation in Octave of types specific to Postgresql

For the general types, defined by SQL and potentially available in each database implementation, see SQL data types.

The last column indicates whether the SQL type is automatically deduced by this packages functions from the representation of the data in Octave. If not, the correct SQL type must be specified by the user if the data is sent from Octave to the database.

cidras inetno
macaddruint8 array of 6 elementsno
uuiduint8 array of 16 elementsno
any enum typestringno

The 8-byte-time value (see time types in SQL data types) can be an int64 scalar, representing microseconds, if the Postgresql server is configured for integer date/time, or a double scalar, representing seconds, if the server is configured for float date/time (deprecated). One can use pq_conninfo to query the respective server configuration.

Geometric point data: if converting from Octave data, any real array (but if of type uint8, the geometric type name must always be specified, for otherwise uint8 would be considered as bytea) with even number of elements. Two adjacent elements (adjacent if indexed with a single index) define a pair of 2D point coordinates. In converting from Postgresql data, dimensions of Octave geometric point data will be chosen to be (2, n_points) and elements will be of format double.

1 Installation hints

Maybe your distribution provides the database package.

If not, or if you want a newer version, Octaves pkg command allows building the package from source and installing it. Note that you have to load any Octave package before you can use it. See Octaves documentation of pkg.

In building from source with pkg, some preconditions of the system are checked, in particular the presence of the pq library of Postgresql. If you have to install a package of your operating system with libpq, you usually also need to install the so called development package (named libpq-dev or similar).

7.4 Examples for accessing Postgresql

The examples assume that there is a database named test and you have the necessary rights to access it without password (probably the database is on a server at the local machine) as the default user, i.e. the user with the same name as your current operating system account.

Each example contains code for cleaning up, but, for more clarity, the cleanup is not enforced with Octaves unwind_protect or with an SQL transaction. If something goes wrong, you can drop the database test – this should assure purging any created large objects.

You can also type demo pq_connect to access some demo code. But it is possibly more difficult to read. test pq_connect runs some functionality tests. The preconditions (access to a database named test) are the same as for the code in the current section.

• Large objects:  Large objects.
• Copy in:  Copy in from Octave variable.
• Composite types:  Working with composite types.

3 Representation in Octave of types defined by SQL

For types specific to database implementations, see Postgresql data types.

The last column indicates whether the SQL type is automatically deduced by this packages functions from the representation of the data in Octave. If not, the correct SQL type must be specified by the user if the data is sent from Octave to the database.

The listed names of SQL data types are those which are used by the functions of this package. They are sometimes different from the original SQL typenames, e.g. int2, int4, and int8 instead of smallint, integer, and bigint, respectively. If not obvious, the original SQL typename is given in parantheses.

any arrayStructure with fields data (holding a cell-array with entries of a type corresponding to the SQL element type), ndims (holding the number of dimensions of the corresponding SQL array, since this can not be deduced from the dimensions of the Octave cell-array in all cases), and optionally (but always present in returned values) lbounds (a row vector of enumeration bases for all dimensions, default is ones (1, ndims); enumeration bases different from 1 are supported e.g. by Postgresql). Array elements may not correspond to arrays in SQL (use additional dimensions for this), but may correspond to composite types, which is allowed to lead to arbitrarily deep nesting.no
any composite type (row type)One-dimensional cell-array with entries of types corresponding to the respective SQL types. Entries may also correspond to an array-type or composite type; this is allowed to lead to arbitrarily deep nesting.no

8-byte-time-value: int64 scalar, representing microseconds, if server is configured for integer date/time; double scalar, representing seconds, if server is configured for float date/time. If the type (integer or float) of an input Octave variable for an 8-byte-time-value does not match the server configuration, there is no automatic conversion but an error is thrown.

Octaves NA corresponds to an SQL NULL value (not NaN, which is interpreted as a value of a float type!).

Features: - number of connections not limited, - mapping of postgresql types to Octave types in data exchange in both directions, - arbitrarily deeply nested composite- and array-types, - caches converter lookups for composite type elements, - binary data transfer, - reads postgresql system catalogs to get type information, - types can be scheme-qualified. State: All commands should work with pq_exec_params, copy from stdin and copy to stdout are implemented from/to files at client side, copy from stdin is also possible from an Octave cell-array. There are no plans to implement copy to stdout into an Octave cell-array (does not safely fit into the framework, and select should be equivalent). The whole framework including conversion of composite and array types with the resulting possible recursion, enum types, and all base types except textsearch types are implemented. Large object import, export, and unlink works, also import/export from/to pipes.

The database package enables accessing SQL databases from Octave. Differences between database implementations will inevitably cause some of this packages functions to be specific for a certain implementation. Currently, however, this package only supports the Postgresql database. Later additions might support further databases, and possibly some general functions (with only very basic functionality), which can be used for all backends, will also be provided. This documentation currently describes the concepts of SQL access in 'database' and the details for Postgresql. Familiarity with SQL and the database implementation (Postgresql) is assumed. @menu * Installation:: Installation hints. * Concept:: Introduction and package concept. * SQL data types:: Representation in Octave of types defined by SQL. * Arbitrary Octave types:: Storing arbitrary Octave types in a database. * Setting options:: Functions for setting or retrieving options. * Documentation:: Function database_doc to view documentation.

If not, or if you want a newer version, Octaves @code{pkg} command allows building the package from source and installing it. Note that you have to @code{load} any Octave package before you can use it. See Octaves documentation of @code{pkg}. In building from source with @code{pkg}, some preconditions of the system are checked, in particular the presence of the @code{pq} library of Postgresql. If you have to install a package of your operating system with @code{libpq}, you usually also need to install the so called development package (named @code{libpq-dev} or similar). @c ------------------------------------------------------------------ @node Concept @chapter Introduction and package concept To enable scripting of SQL access, particularly combinations of SQL commands with temporary local storage or local processing of data, for almost each SQL data type a corresponding representation of the data in Octave is defined. This includes the SQL array types and user-defined SQL composite types (row types) of arbitrary nesting depth. Octave variables containing these corresponding representations are created by the package if data is received from a database by a @code{select} query, and correspondingly are used for sending data to the database. This data exchange is lossless if the database backend allows it (which is the case for Postgresql). The representations of SQL types in Octave are the 'naturally' corresponding Octave types, if possible. They can also be created directly in Octave and sent to a database. The package keeps a notion of all SQL types available in a database. This information is automatically retrieved after connecting. If the user creates new types with SQL commands, a package function for refreshing the packages information on types must be called for the type to be available within the same session. The same function should be called if the session continues after deletion of types. The package provides functions for issuing SQL commands whose text is provided by the user. The command text can contain placeholders for data. The data, corresponding to these placeholders, can be passed to the function in separate arguments. In queries, not only data is returned, but also information on data type and column names. @c ------------------------------------------------------------------ @node SQL data types @chapter Representation in Octave of types defined by SQL @cindex data types For types specific to database implementations, @mysee @ref{Postgresql data types}.

The database package enables accessing SQL databases from Octave. Differences between database implementations will inevitably cause some of this packages functions to be specific for a certain implementation. Currently, however, this package only supports the Postgresql database. Later additions might support further databases, and possibly some general functions (with only very basic functionality), which can be used for all backends, will also be provided. This documentation currently describes the concepts of SQL access in 'database' and the details for Postgresql. Familiarity with SQL and the database implementation (Postgresql) is assumed. @menu * Installation:: Installation hints. * Concept:: Introduction and package concept. * SQL data types:: Representation in Octave of types defined by SQL. * Arbitrary Octave types:: Storing arbitrary Octave types in a database. * Setting options:: Functions for setting or retrieving options. * Documentation:: Function database_doc to view documentation.

If not, or if you want a newer version, Octaves @code{pkg} command allows building the package from source and installing it. Note that you have to @code{load} any Octave package before you can use it. See Octaves documentation of @code{pkg}. In building from source with @code{pkg}, some preconditions of the system are checked, in particular the presence of the @code{pq} library of Postgresql. If you have to install a package of your operating system with @code{libpq}, you usually also need to install the so called development package (named @code{libpq-dev} or similar). @c ------------------------------------------------------------------ @node Concept @chapter Introduction and package concept To enable scripting of SQL access, particularly combinations of SQL commands with temporary local storage or local processing of data, for almost each SQL data type a corresponding representation of the data in Octave is defined. This includes the SQL array types and user-defined SQL composite types (row types) of arbitrary nesting depth. Octave variables containing these corresponding representations are created by the package if data is received from a database by a @code{select} query, and correspondingly are used for sending data to the database. This data exchange is lossless if the database backend allows it (which is the case for Postgresql). The representations of SQL types in Octave are the 'naturally' corresponding Octave types, if possible. They can also be created directly in Octave and sent to a database. The package keeps a notion of all SQL types available in a database. This information is automatically retrieved after connecting. If the user creates new types with SQL commands, a package function for refreshing the packages information on types must be called for the type to be available within the same session. The same function should be called if the session continues after deletion of types. The package provides functions for issuing SQL commands whose text is provided by the user. The command text can contain placeholders for data. The data, corresponding to these placeholders, can be passed to the function in separate arguments. In queries, not only data is returned, but also information on data type and column names. @c ------------------------------------------------------------------ @node SQL data types @chapter Representation in Octave of types defined by SQL @cindex data types For types specific to database implementations, @mysee @ref{Postgresql data types}. The last column indicates whether the SQL type is automatically deduced by this packages functions from the representation of the data in Octave. If not, the correct SQL type must be specified by the user if the data is sent from Octave to the database. The listed names of SQL data types are those which are used by the functions of this package. They are sometimes different from the original SQL typenames, e.g. @code{int2}, @code{int4}, and @code{int8} instead of @code{smallint}, @code{integer}, and @code{bigint}, respectively. If not obvious, the original SQL typename is given in parantheses. @multitable {aaaaaaaaaaaaa} {Octave type blah blah blah blah blah} {auto} @headitem SQL @tab Octave @tab auto @item bool @tab logical scalar @tab yes @item bytea (variable length binary string) @tab array of uint8, one-dimensional if converted from SQL data @tab yes @item float8 @tab double scalar @tab yes @item float4 @tab single scalar @tab yes @item varchar @tab string @tab no @item bpchar (char) @tab string @tab no @item int2 @tab int16 scalar @tab yes @item int4 @tab int32 scalar @tab yes @item int8 @tab int64 scalar @tab yes @item timestamp @tab 8-byte-time-value (see below), positive or negative difference to 2000-01-01 00:00 @tab no @item timestamptz @tab as timestamp @tab no @item time @tab 8-byte-time-value (see below) @tab no @item timetz @tab 2-element cell array with 8-byte-time-value (see below, time of day) and int32 scalar (time zone in seconds, negative east of UTC) @tab no @item date @tab int32 scalar, positive or negative difference to 2000-01-01 @tab no @item interval @tab 3-element cell array with 8-byte-time-value (see below), int32 (days), and int32 (months) @tab no @item bit @tab structure with fields @code{bitlen} (int32, number of valid bits) and @code{bits} (uint8 array, 8 bits per entry, first entry contains the leftmost bits, last entry may contain less than 8 bits) @tab no @item varbit @tab as bit @tab yes @item xml @tab string @tab no @item any array @tab Structure with fields @code{data} (holding a cell-array with entries of a type corresponding to the SQL element type), @code{ndims} (holding the number of dimensions of the corresponding SQL array, since this can not be deduced from the dimensions of the Octave cell-array in all cases), and optionally (but always present in returned values) @code{lbounds} (a row vector of enumeration bases for all dimensions, default is @code{ones (1, ndims)}; enumeration bases different from @code{1} are supported e.g. by Postgresql).

File: database.info, Node: Top, Next: Installation, Up: (dir) General documentation for the database package for Octave ********************************************************* This documentation applies to version 2.4.4 of the database package. The database package enables accessing SQL databases from Octave. Differences between database implementations will inevitably cause some of this packages functions to be specific for a certain implementation. Currently, however, this package only supports the Postgresql database. Later additions might support further databases, and possibly some general functions (with only very basic functionality), which can be used for all backends, will also be provided. This documentation currently describes the concepts of SQL access in 'database' and the details for Postgresql. Familiarity with SQL and the database implementation (Postgresql) is assumed. * Menu: * Installation:: Installation hints. * Concept:: Introduction and package concept. * SQL data types:: Representation in Octave of types defined by SQL. * Arbitrary Octave types:: Storing arbitrary Octave types in a database. * Setting options:: Functions for setting or retrieving options. * Documentation:: Function database_doc to view documentation.

File: database.info, Node: Installation, Next: Concept, Prev: Top, Up: Top 1 Installation hints ******************** Maybe your distribution provides the database package. If not, or if you want a newer version, Octaves 'pkg' command allows building the package from source and installing it. Note that you have to 'load' any Octave package before you can use it. See Octaves documentation of 'pkg'. In building from source with 'pkg', some preconditions of the system are checked, in particular the presence of the 'pq' library of Postgresql. If you have to install a package of your operating system with 'libpq', you usually also need to install the so called development package (named 'libpq-dev' or similar).  File: database.info, Node: Concept, Next: SQL data types, Prev: Installation, Up: Top 2 Introduction and package concept ********************************** To enable scripting of SQL access, particularly combinations of SQL commands with temporary local storage or local processing of data, for almost each SQL data type a corresponding representation of the data in Octave is defined. This includes the SQL array types and user-defined SQL composite types (row types) of arbitrary nesting depth. Octave variables containing these corresponding representations are created by the package if data is received from a database by a 'select' query, and correspondingly are used for sending data to the database. This data exchange is lossless if the database backend allows it (which is the case for Postgresql). The representations of SQL types in Octave are the 'naturally' corresponding Octave types, if possible. They can also be created directly in Octave and sent to a database. The package keeps a notion of all SQL types available in a database. This information is automatically retrieved after connecting. If the user creates new types with SQL commands, a package function for refreshing the packages information on types must be called for the type to be available within the same session. The same function should be called if the session continues after deletion of types. The package provides functions for issuing SQL commands whose text is provided by the user. The command text can contain placeholders for data. The data, corresponding to these placeholders, can be passed to the function in separate arguments. In queries, not only data is returned, but also information on data type and column names.  File: database.info, Node: SQL data types, Next: Arbitrary Octave types, Prev: Concept, Up: Top 3 Representation in Octave of types defined by SQL ************************************************** For types specific to database implementations, *note Postgresql data types::. The last column indicates whether the SQL type is automatically deduced by this packages functions from the representation of the data in Octave. If not, the correct SQL type must be specified by the user if the data is sent from Octave to the database. The listed names of SQL data types are those which are used by the functions of this package. They are sometimes different from the original SQL typenames, e.g. 'int2', 'int4', and 'int8' instead of 'smallint', 'integer', and 'bigint', respectively. If not obvious, the original SQL typename is given in parantheses.

Array elements may not correspond to arrays in SQL (use additional dimensions for this), but may correspond to composite types, which is allowed to lead to arbitrarily deep nesting. any composite One-dimensional cell-array with no type (row entries of types corresponding to type) the respective SQL types. Entries may also correspond to an array-type or composite type; this is allowed to lead to arbitrarily deep nesting. 8-byte-time-value: int64 scalar, representing microseconds, if server is configured for integer date/time; double scalar, representing seconds, if server is configured for float date/time. If the type (integer or float) of an input Octave variable for an 8-byte-time-value does not match the server configuration, there is no automatic conversion but an error is thrown. Octaves 'NA' corresponds to an SQL NULL value (not 'NaN', which is interpreted as a value of a float type!).  File: database.info, Node: Arbitrary Octave types, Next: Setting options, Prev: SQL data types, Up: Top 4 Storing arbitrary Octave types in a database ********************************************** If Octave variable types have corresponding SQL types ( *note SQL data types:: , also consider the links there to types specific for database implementations), the variables can directly be stored in a database. If not, the variables can be converted to representations of the SQL type bytea and then stored. This way of storing is possible for all Octave types which can be correctly saved and loaded with Octaves 'save' and 'load' functions. * Menu: * var2bytea:: Converting Octave variables to bytea. * bytea2var:: Converting bytea back to Octave variables.  File: database.info, Node: var2bytea, Next: bytea2var, Up: Arbitrary Octave types 4.1 Converting Octave variables to bytea ======================================== -- Loadable Function: var2bytea (VALUE, ...) Save input values in uint8 arrays in Octaves binary save format. This function returns as many output variables as input variables are given. The function can be used to prepare storage of Octave variable values as binary strings in a database, if the variables types have no corresponding SQL type. Each variable type which can be correctly saved and loaded with Octaves 'save' and 'load' functions is acceptable. The variable value can be restored with the function 'bytea2var'. Note that the inputs are not variable names, but values. No variable names are saved. Loading the uint8 array with 'load' (possibly after dumping it to a file) will not work. Example: to convert the first and third column of a cell-array 'c', '[c{:, [1, 3]}] = var2bytea (c{:, [1, 3]});' can be used. See also: *note bytea2var: XREFbytea2var.

Postgresql Octave auto ---------------------------------------------------------------- oid uint32 scalar yes text string yes name string of length < 'NAMEDATALEN' no (often 64) money int64 scalar, which is 100 times the no currency value to enable storing the 'small currency' (e.g. Cent) fraction in the last two digits point geometric point data for one point yes (see below) lseg geometric point data for two points yes (see below) line (not yet as lseg no implemented by postgresql-9.2.4) box as lseg no circle real vector (but the restrictions yes for type uint8 as in geometric element type apply, as explained below) with 3 elements, no. 1 and 2 centre coordinates, no. 3 radius polygon geometric point data (see below) no path structure with fields 'closed' no (boolean, is path closed?) and 'path' (geometric point data, see below). inet uint8 array of 4 or 5 elements for no IPv4 or uint16 array of 8 or 9 elements for IPv6. 5th or 9th element, respectively, contain number of set bits in network mask, the default (if there are only 4 or 8 elements, respectively) is all bits set. cidr as inet no macaddr uint8 array of 6 elements no uuid uint8 array of 16 elements no any enum type string no The 8-byte-time value (see time types in *note SQL data types::) can be an int64 scalar, representing microseconds, if the Postgresql server is configured for integer date/time, or a double scalar, representing seconds, if the server is configured for float date/time (deprecated). One can use *note pq_conninfo:: to query the respective server configuration. Geometric point data: if converting from Octave data, any real array (but if of type uint8, the geometric type name must always be specified, for otherwise uint8 would be considered as bytea) with even number of elements. Two adjacent elements (adjacent if indexed with a single index) define a pair of 2D point coordinates. In converting from Postgresql data, dimensions of Octave geometric point data will be chosen to be (2, n_points) and elements will be of format double.

File: database.info, Node: pq_connect, Next: pq_close, Up: Connection functions 7.2.1 Connecting to a Postgresql database ----------------------------------------- -- Function File: CONNECTION = pq_connect (SETTINGS) Establishes a connection to a postgresql server according to SETTINGS and returns an 'octave_pq_connection' object CONNECTION which can be passed to other functions of the package. There can be multiple connections. An 'octave_pq_connection' object contains information on a connection and will be internally altered by the packages functions even though it is only passed as an argument, i.e. Octaves 'pass by value' semantics are not adhered to in this case. SETTINGS can be set by 'setdbopts' (copied from Octaves 'optimset') and can contain (defaults depend on Postgresql): 'host' (hostname), 'hostaddr' (numeric host address), 'port' (port to connect to), 'dbname' (database to connect to), 'user' (user name to connect as), 'password', 'connect_timeout', 'options' (command-line options to send to the server at run-time, see Postgresql documentation), 'sslmode' ('disable', 'allow', 'prefer', 'require', 'verify-ca', or 'verify-full'; see Postgresql documentation of SSL support), 'sslcert' (file name of client SSL certificate), 'sslkey' (location of secret key for client certificate, file name or external OpenSSL engine (colon-separated engine name and an engine-specific key identifier)), 'sslrootcert' (file name of root SSL certificate), 'sslcrl' (file name of SSL certificate revocation list), 'krbsrvname' (kerberos service name), 'service' (service name in pq_service.conf to use for additional parameters). All these settings are passed to the server as they are, so it may be better to consult the postgresql documentation for them, e.g. the documentation of the PQconnectdb function in libpq.

File: database.info, Node: pq_close, Next: pq_conninfo, Prev: pq_connect, Up: Connection functions 7.2.2 Disconnecting from a Postgresql database ---------------------------------------------- -- Loadable Function: pq_close (CONNECTION) Closes connection CONNECTION to a postgresql server. See also: *note pq_connect: XREFpq_connect.  File: database.info, Node: pq_conninfo, Prev: pq_close, Up: Connection functions 7.2.3 Retrieving information on the connection and on the server ---------------------------------------------------------------- -- Loadable Function: VAL = pq_conninfo (CONNECTION, LABEL) Retrieves connection information for postgresql connection CONNECTION, specified by the string LABEL, and returns the value of this information in VAL. The type of VAL depends on the requested information. Currently, the only recognized LABEL is ''integer_datetimes''; VAL is 'true' if 8-byte date and time values are stored as integer in the server, and 'false' if they are stored as 'double' (which is deprecated).  File: database.info, Node: Data exchange, Next: Examples, Prev: Connection functions, Up: Postgresql 7.3 Functions for data exchange with a Postgresql database ========================================================== * Menu: * pq_exec_params:: Issuing SQL commands. * pq_update_types:: Updating type information. Large objects * pq_lo_import:: Importing large objects into a database. * pq_lo_export:: Exporting large objects from a database. * pq_lo_unlink:: Deleting large objects from a database. * pq_lo_view:: Viewing large objects.  File: database.info, Node: pq_exec_params, Next: pq_update_types, Up: Data exchange 7.3.1 Issuing SQL commands -------------------------- -- Function File: pq_exec_params (CONNECTION, COMMAND) -- Loadable Function: pq_exec_params (CONNECTION, COMMAND, PARAMS) -- Loadable Function: pq_exec_params (CONNECTION, COMMAND, SETTINGS) -- Loadable Function: pq_exec_params (CONNECTION, COMMAND, PARAMS, SETTINGS) Sends the string COMMAND, which must contain a single SQL command, over the connection CONNECTION. Parameters in COMMAND can be replaced by $1, $2, etc and their values given in the one-dimensional cell-array PARAMS. Parameters of composite type sent this way must have their type defined in the database. For typeconversions, the package maintains a notion of defined types, which should be refreshed with 'pq_update_types' if types are defined or dropped after establishing the connection, or if the schema search path changes. SETTINGS is a structure of settings, it can be created by 'setdbopts'. Settings currently understood by 'pq_exec_params': 'param_types' One-dimensional cell-array with type specifications for parameters in PARAMS. If present, must have the same length as PARAMS. Entries may be empty if no specification is necessary (see below). Type specifications are strings corresponding to the entries returned by 'SELECT typname FROM pg_type WHERE typarray != 0 OR typtype = 'c';', optionally having '[]' appended (without space) to indicate an array. Type specifications can be schema-qualified, otherwise they refer to the visible type with that name. 'copy_in_path, copy_out_path' Path to files at the client side for 'copy from stdin' and 'copy to stdout', respectively. 'copy_in_from_variable' Logical scalar, default 'false'. If 'true', 'copy from stdin' uses data from an Octave variable instead of from a file. 'copy_in_data' 2-dimensional cell-array with columns of suitable type (see below) - will be used instead of a file as data for 'copy from stdin' if 'copy_in_from_variable' is 'true'. 'copy_in_types' If some columns in 'copy_in_data' need a type specification (see below), 'copy_in_types' has to be set to a cell-array with type specifications, with an entry (possibly empty) for each column. 'copy_in_with_oids' If you want to copy in with oids when using data from an Octave variable, the first column of the data must contain the OIDs and 'copy_in_with_oids' has to be set to 'true' (default 'false'); 'with oids' should be specified together with 'copy from stdin' in the command, otherwise Postgresql will ignore the copied oids. There is no way to 'copy to stdout' into an Octave variable, but a 'select' command can be used for this purpose. 'copy from stdin' from an Octave variable is only supported in binary mode, so this has to be specified in the SQL command. The output depends on the type of command. * queries (commands potentially returning data): The output will be a structure with fields 'data' (containing a cell array with the data, columns correspond to returned database columns, rows correspond to returned tuples), 'columns' (containing the column headers), and 'types' (a structure-vector with the postgresql data types of the columns, subfields 'name' (string with typename), 'is_array' (boolean), 'is_composite' (boolean), 'is_enum' (boolean), and 'elements' (if 'is_composite == true', structure-vector of element types, containing fields corresponding to those of 'types')). * copy commands: Nothing is returned (this may change in the future). * other commands: The output will be the number of affected rows in the database.

File: database.info, Node: pq_update_types, Next: pq_lo_import, Prev: pq_exec_params, Up: Data exchange 7.3.2 Updating type information ------------------------------- -- Loadable Function: pq_update_types (CONNECTION) Updates information on existing postgresql types for CONNECTION. Use this before 'pq_exec_params' if types were created or dropped while the connection was already established or if the schema search path changed. A newly created connection will automatically retrieve this information at connection time.  File: database.info, Node: pq_lo_import, Next: pq_lo_export, Prev: pq_update_types, Up: Data exchange 7.3.3 Importing large objects into a database --------------------------------------------- -- Loadable Function: OID = pq_lo_import (CONNECTION, PATH) Imports the file in PATH on the client side as a large object into the database associated with CONNECTION and returns the Oid of the new large object. If PATH ends with a '|', it is take as a shell command whose output is piped into a large object.  File: database.info, Node: pq_lo_export, Next: pq_lo_unlink, Prev: pq_lo_import, Up: Data exchange 7.3.4 Exporting large objects from a database --------------------------------------------- -- Loadable Function: pq_lo_export (CONNECTION, OID, PATH) Exports the large object of Oid OID in the database associated with CONNECTION to the file PATH on the client side. If PATH starts with a '|', it is taken as a shell commant to pipe to.  File: database.info, Node: pq_lo_unlink, Next: pq_lo_view, Prev: pq_lo_export, Up: Data exchange 7.3.5 Deleting large objects from a database -------------------------------------------- -- Loadable Function: pq_lo_unlink (CONNECTION, OID) Removes the large object of Oid OID from the database associated with CONNECTION.  File: database.info, Node: pq_lo_view, Prev: pq_lo_unlink, Up: Data exchange 7.3.6 Viewing large objects --------------------------- -- Function File: pq_lo_view (CONNECTION, OID, VIEWER) Exports the large object of Oid OID in the database associated with CONNECTION to a temporary file and starts the program VIEWER in the background with the name of the temporary file as argument. The temporary file will be removed after termination of the viewer.  File: database.info, Node: Examples, Prev: Data exchange, Up: Postgresql 7.4 Examples for accessing Postgresql ===================================== The examples assume that there is a database named 'test' and you have the necessary rights to access it without password (probably the database is on a server at the local machine) as the default user, i.e. the user with the same name as your current operating system account. Each example contains code for cleaning up, but, for more clarity, the cleanup is not enforced with Octaves 'unwind_protect' or with an SQL transaction. If something goes wrong, you can drop the database 'test' - this should assure purging any created large objects. You can also type 'demo pq_connect' to access some demo code. But it is possibly more difficult to read. 'test pq_connect' runs some functionality tests. The preconditions (access to a database named 'test') are the same as for the code in the current section. * Menu: * Large objects:: Large objects. * Copy in:: Copy in from Octave variable. * Composite types:: Working with composite types.
