In the real world, applications which use use pulldown lists (sometimes nested), querying a database to gather the list (and marshal the values into a form required by the menu interface) is just too costly to performance. As soon as SQLite provides an interface that matches a SELECT query to an arbitrary in-memory structure, I'll be glad to give it a whirl. However, I think you'd agree that it's the application's responsibility to provide the data in a form that matches the interface, not the database's responsibility.
