[MonetDB-users] Recursing into a tree via SQL?

Hi, I've been wondering whether MonetDB/SQL provides something equivalent to Oracle's START WITH ... CONNECT BY ... and if not, how difficult would it be to emulate the behavior with user functions. For example, PostgreSQL provides connectby() function which does that. The table in question is like that: id int, parent_id int, other stuff And it holds multiple small trees, with the root node for each having NULL parent_id.
