about

MySQL UDFs offer a powerful way to extend the functionality of your MySQL database.

The UDFs on this site are all free: free to use, free to distribute, free to modify and free of charge. Even for commercial projects.

Libraries

For downloads, place navigate to either one of the library documentation pages. You will find the source, binary and resources in the top of each documentation page.

Please understand that in most cases, the libraries themselves are not considered complete. We intend to add more functions to these libraries. However, we are currently not thinking of changing any of the function names or signatures, so it should be safe to build with whatever is there now.

Currently, the following libraries are available:

lib_mysqludf_json
A library of functions to map relational data to the JSON format. JSON is a principal format next to XML for data exchange in AJAX architectures.
Contributed by Roland Bouman
lib_mysqludf_log
No info of this library available
lib_mysqludf_preg
A library to access the functionality in the PCRE library, offering Perl 5 compatible regular expressions. This can be as an enhancement to (or replacement of) the RLIKE or REGEXP syntax native to MySQL, or to replace regular expressions in the client or application layer (such as the PHP preg_ functions).

lib_mysqludf_stat
A library of statistical functions. Most of these functions are aggregrate functions.

lib_mysqludf_stem

lib_mysqludf_str
