Yes, although imagine:
DELETE FROM staff USING users JOIN logons USING (user_id)
WHERE last_logon < ( now() - '6 months');
Not as bad as FROM, but still a bit baffling to look at. Still, I can't
think of anything else that wouldn't require inventing a new reserved word.
Oh, and MySQL's "multi-table deletes": PLEASE tell me that's not
SQL-standard.
