What would this express? Why do you need NULLS? for the original use of the junction table, you won't need NULLS at all. How is a particular user connected to this "record" you're creating? (Incidentally, I use the term "row" in preference to "record" when discussing tables. Some writers do the opposite, however). Received on Tue Apr 07 2009 - 13:59:15 CEST
