Oh yes, line feeds definitely made it a lot more understandable!
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.
