yikes - the whole idea of having an rdbms is that it maintains integrity of data. And data without unique primary keys is not data, it is junk. If you are going to waste time and code maintaining data integrity in your application logic, you might as well use flat files to store your data. What you are doing is shutting down your car engine and getting it pulled by a horse. Either use the engine or use something more lightweight to ease the burden on the horse. -- regards kg http://www.livejournal.com/users/lawgon tally ho! http://avsap.org.in ಇಂಡ್ಲಿನಕ್ಸ வாழ்க!
