Yes, you've run into one of the query optimizer's dirty little secrets. It's not too bright at trying to optimzie big joins. :-( But you seem to be using STRAIGHT JOINs a lot, so that *should* cut down on the effort needed. But maybe it's a bit dumber than I thought. You might file this as a bug report. It couldn't hurt, I guess. Jeremy -- Jeremy D.
