Pascal Data Objects

Unsatisfied with the available libraries for object Pascal to connect to various databases with a standard API, I created “Pascal Data Objects” which is loosely patterned after PHP Data Objects, and originally supported MySQL 4.0, 4.1, and 5.0 using native client libraries. I recently moved the project to Sourceforge ( pdo.sourceforge.net ) and added support for Firebird 1.5 and 2.0.

PDO is licensed LGPL as it contains some code from Zeoslib, which is LGPL. One particularly nice thing about my implementation of the Firebird drivers is that I built in “prefetch” support. By default, the driver prefetches the entire result set and stores it internally so that functions that depend on knowing how big a result set is before accessing the data can be supported. There is also some data abstraction functions.

The source code is packaged at Sourceforge and works on Delphi and Free Pascal Compiler, tested and used in both Windows and FreeBSD programs. If you decide that this is newsworthy, then I’ll leave the wording up to you.
