i'm not precicely an expert on sql either, but i'm not following you. i
can guarantee that its a shallow tree but i cant guarantee its depth. it
could be anywhere from 1 to 3 levels. i dont suppose you'd care to put
down an example of some sql that might be applicable? i just dont see
how a join would help?
thanks!
