Remove all signatures?

[RaceJunkie]

I just updated my signature permissions and I was wondering if there is a query that can be ran to remove all current signatures forcing members to redo them and obey the new sig permissions?

UPDATE usertextfield SET signature = ''

Just what the doctor ordered, thanks very much.

Is there a list of sql queries somewhere?

I believe there is a list over @ vBulletin.com forums.
