Thank you Jeff.
And thanks for pointing out the RBAR aspect of recursive queries. I'm still not very good at spotting hidden RBAR, and you are the master of that subject.
I remember reading an article by you about triangular joins being RBAR, it was very enlightening.
Do you happen to have a posted example of a non-RBAR hierarchal query? I'd really like to see how that is done. I've been very impressed by your postings that I have read.
