SQL-3, that's what became sql99, isn't it? Anyway, there is nothing like what you explained in sql 99 nor sql 2003. The boolean type have a third value called UNKNOWN that is just an alias of NULL, that's about all the changes as I can recall in the NULL area. -- /Dennis Björklund ---------------------------(end of broadcast)--------------------------- TIP 6: explain analyze is your friend
