Does ON DELETE CASCADE not work for you?

Other than that you would have do do outer join acrobatics ;-)

Subject: [GENERAL] Deleting orphan records

Does anybody have a method for deleting orphan (unreferenced) records? Is it possible to set up some sort of constraint or trigger (that performs well when lots of records are deleted ;) )?
