Do you know if your implementation will support multiple childs for each node or will the implementation be limited to one link from each node in the tree (making the tree to a list)? I mean, given the table below: NODEID, CHILDID 1 10 1 11 1 12 10 NULL 11 111 11 112 12 NULL 2 21 3 22 21 NULL 22 NULL 111 NULL 112 NULL -will I then be able to fetch all childs (and grandchilds) for a given node in the above tree in one single query (fx. getting the whole tree when asking for nodeid = 1 and all its childs)? I'm asking because I somewere heard/read that SQL3 (SQL99) does not support multiple childs (but I hope you will implement the "large" version).
