    Sorry to disappoint you guys but I wasn't able to come up with anything.

    My gut was telling me an rCTE wouldn't do it and the set-based loop I tried wouldn't resolve it out properly either.

    Of course, I could be wrong as I'm a bit out of practice writing rCTEs! 🙂

    I'm not surprised, Dwain. It's quite tricky. The more obvious methods like MAX() OVER() won't work when you expect them to, in the recursive part.
