Finding the "last node" in a hierarchical query?

784546Jul 12 2010 — edited Jul 13 2010

I'm presented with an issue - find all parent records for which the "last node" in a hierarchy is not set to some value.

Table structure:

child_id number
parent_id number
type_id number

So, I need to find all parents whose eventual last "children" (could be several levels deep, it varies) do not have a type_id of 29.

I can find the hierarchy easily using connect by prior but I'm stuck on that "last node" bit. Any help out there?
