If I read you correct, your productoptions table is basically a lookup table and as such all your fields should be foreign keys. Because, each field is a reference to another table - and it's vital to data consistency that they cannot point to a row in a table that doesn't exist. -- <hype> WWW: http://plphp.dk / http://plind.dk LinkedIn: http://www.linkedin.com/in/plind Flickr: http://www.flickr.com/photos/fake51 BeWelcome: Fake51 Couchsurfing: Fake51 </hype> -- PHP Database Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
