Emptying mySQl database on time-based factor!!!

Can we set a time out for deleting entries in the mySQl databased on a certain criteria?? This may sound akward maybe... but let's see this... Someone's been entering stuff into mySQL db. He goes away.. and maybe after one or tw0 hours of his dissapearing act..i would like records pertaining to him from the table be deleted!! Taking maybe his name into 'criteria'. Help Appreciated. ===== Rahul S. Johari (Director) ****************************************** Abraxas Technologies Inc.
