The ibase unit.
Free Pascal interface to Interbase/Firebird
OverviewYou can use Free Pascal to access a Interbase or Firebird database server from Linux and Windows. For more info on Interbase, see their home page.)
For more information on Firebird, see their home page.
Interfacing is very easy, all you need to do is compile some units, and use these units in your program. You need to specify the place of the Interbase client Library (libgds when compiling, and that is it. the provided units take care of the rest.
RequirementsYou need at least version 0.99.11 of Free Pascal. The headers are translated for Interbase versions 4 and 6, or Firebird 1.0.
InstallationThe ibase unit is distributed as part of the Free Pascal packages, and is distributed with the compiler.
This file contains a directory base/ibase with the units, a test program and a make file. The following units exist:
- ibase40 the Interbase version 4 or 5 interface header translation. The interface is largely the same as for version 6.
- ibase60 the Interbase version 6 interface header translation. (View Interface).
makeShould compile the units and the program. If compilation was succesfull, you can install with
make install(Remember to set the directory where the units should be installed.)
You can then test the program by running
make testThis will:
- Run a script to create a table in a database, and fill it with some data. (the isql program should be in your PATH for this) . By default, the used database is testdb.
- Run the testprogram testdb
- Run a shell script again to remove the created table.
Future plansThe interface to Interbase is a pure translation of the Interbase C header files. This means that the used functions are rather un-pascalish. It would be great to have an OOP interface for it, A la Delphi. This OOP interface is being worked on.
FinallyIf you have found a bug, or if you have made some functions to interface these units in a more pascal-like fashion, feel free to contact me at firstname.lastname@example.org
