MySQL

My Regular Exrepssion UDFs for MySQL have been available on MySQL Forge for a while already, now i've taken the time to create a Trac project page for them.

I've implemented the following four functions

* REGEXP_LIKE(text, pattern [, mode])
* REGEXP_SUBSTR(text, pattern)
* REGEXP_INSTR(text, pattern [,position [,occurence [,return_end [,mode]]]])
* REGEXP_REPLACE(text, pattern, replace)

that behave very similar to their Oracle counterparts, using the same regular expression syntax as the MySQL REGEXP operator.
