Hi!

I have a SQL problem here, which I can't solve.

I have a B-tree structure in a table (parentID, childID).

If a parent has kids then select those kids. If not, select this parent.

How do I code this in SQL? I tried using "connect by" but this doesn't include start point.

Any idea?

This is 8.1.6 on Win2k.

Thanks,
Helmut
