Script allows you to purge old data from kayako database (Kayako helpdesk solution, http://kayako.com/).
Usage is pretty easy, you have to run something like this:
$ mysql -D kayakodb -u dbuser -p < cleaner.sql
By default this script removes all tickets older than 90 days. The point is in editing the query that collects ticket ids, so if you want any complex criteria - write it here:
INSERT INTO ticketids(ticketid)
SELECT ticketid FROM swtickets WHERE (dateline + (86400 * 90) < UNIX_TIMESTAMP(NOW()));
Run the clean-trash.sql script
