I would think that recursion is the best choice when needing to get a path through a tree structure. Any other methods I've seen (but I'm sure I haven't seen them all), either need to loop much more times than a recursive call would, or results in more database hits (kind of a mute point if it's happening completely in a stored proc).
My thoughts.

I do not remember where, but it does not use recursion. Recursion is very cool (I happen to love it) but is not terribly efficient, probably why LISP never caught on.
