I suppose what you need here is a good mapper for your application (e.g., hibernate, but hey, you did not mention your application language). I suspect you are asking for a lazy master-child table lookup but hey, you did not mention your tables. This could help: http://qt-project.org/doc/qt-4.8/sql-masterdetail.html but I recommend you getting either a better knowledge of your aim or a good SQL/relational theory book. Luca
