P.S. Table_Dee is not a valid result for Intersection because intersection is defined on specific types of relations and not on general relations the way Join is defined. A universal relation on RT is not a valid result for Join because Join is not defined on a specific type the way Intersection is. Received on Sat Jun 10 2006 - 18:21:50 CEST
