I'm trying to get my head around why SQL composite types are a good way to marshal complex object graphs with recursion. I can see where it could be done, I'm still not convinced that it's better than SQL passing out data in tabular form with relationship established by matching values. In other words, when is it a good idea to do the relation to object mapping in the database engine? -Kevin
