operationsengineer1@yahoo.com...... So you have three tables: > T product_base > T revision > T product_revision I don't understand the difference between revision and product revision. Maybe product_revision is a cross reference of the first two tables? What kind of queries would you make? I don't really see the sense of asking what products have a revision 4. What are these products anyway? Maybe it would make sense to ask who uses a product a revision 4 level, but you don't have a users table. I think we need more info as to what you are trying to do. brew ========================================================================== Strange Brew (brew@theMode.com) Check out my Stock Option Covered Call website http://www.callpix.com and my Musician's Online Database Exchange http://www.TheMode.com ==========================================================================
