A collection of various more or less useful auxiliary stored procedures and functions for the Firebird DBMS

Useful Firebird SQL

What Is It?

This is a collection of various auxiliary stored procedures, stored functions, queries, and executable blocks for the Firebird DBMS. Some of them I use in my daily work, and some were created by me just for fun, but I think that they could be useful (or just funny) to someone else. I have been collecting them for a long time, and it is likely that the list will be replenished in the future. At least I created more scripts, but it’s just that I don’t have time to neatly format and test them, and write a readme.

The algorithms are presented as SQL queries and PSQL scripts. Most of them exist in two forms: as a stored procedure (for compatibility with Firebird versions lower than 3) and as a stored function (for Firebird 3 and above). Some algorithms return a dataset so they cannot be represented as a stored function, but only as a stored procedure.

All of the stored procedures are compatible with Firebird versions 2.5 and 3 and have been tested on those versions. They must also be compatible with newer versions of the DBMS. Some procedures are compatible with Firebird 2.1 and even 1.5 — I always write the minimum version in the Syntax section of their readme.

All stored functions presented are for Firebird version 3 and above only.

Each script (represented as a stored procedure, a stored function, a pair of stored procedure and function, etc.) that solves a specific task is placed in a separate subfolder along with its own readme file.

List Of Procedures, Functions, And Queries

in alphabetical order

• FORMAT_DATE — format date using a template.
• GEN_PASSWORD — generate a random password.
• INT2HEX — convert an integer to a hexadecimal string.
• RecursivePrivileges — recursively read from the metadata the access privileges of a given database subject (user, role, stored procedure, trigger, etc.) on various DB objects (tables, stored procedures, etc.).
• SPLIT — convert a string containing a delimited list to a table, i.e. perform the opposite task of the list aggregate function.

For more information, please read the readme file in the corresponding subfolder.
