All,

I am building a form where a heirarchical tree control would be very useful. In the documentation I have looked at, they only speak of querying heirarchical tables with self joins. Has anyone queried multi-level master detail relationships in to a tree? For example, If I had a Houses table, a rooms table and a furniture table - for lack of a better example, and wanted to have a house which can be clicked on, showing rooms, which have furniture items underneath. Would a view based on these tables joined by their primary keys be usable in a heirarchical tree using the psuedo columns Level, etc. I need to read further to understand the queries, but if anyone has had experience, a simple example would be very helpful.

Thanks very much
