Firebird FreeUDFLib 1.1

Firebird FreeUDFLib, developed by IVIZ Software Ltda., is a comprehensive library of external user-defined functions (UDFs) for the Firebird relational database, with compatibility for legacy InterBase systems. It extends SQL with a practical set of utilities that simplify everyday data manipulation and fill gaps found in older database versions.

Key function categories include:

• String operations: trimming and padding, case conversion, substring and search, character translation, and text conversions.
• Numeric utilities: rounding, truncation, absolute values, and text–number conversions.
• Date and time helpers: extracting components, adding or comparing intervals, and basic formatting.
• Miscellaneous utilities: commonly used helpers for data handling, including support for larger text fields.

Distributed as a shared library (DLL/SO), FreeUDFLib is easy to deploy and can be used in SQL statements, stored procedures, and triggers. It is especially valuable for maintaining existing databases and applications that rely on UDFs. While newer versions of Firebird provide more built-in functions and alternative extension mechanisms, FreeUDFLib remains a reliable, widely adopted option for enhancing SQL functionality with minimal effort.
