Hi all, I have 2 tables: table1 with the columns objectid, refobjectid, commonvaluecol and value1. table2 with the columns objectid, refobjectid, commonvaluecol and value2. A "select * from table2 where commonvaluecol = 123 and value2 > 0" returns no rows. I create a view: create view miracle as select table1.objectid, table1.value1, table1.commonvalue, table1.refobjectid, table2.value2 from table1 joing table2 on table1.refobjectid = table2.refobjectid where commonvaluecol = 123 Than I do a "select * from miracle where commonvaluecol = 123 and value2 > 0" This query returns many rows. (How) Is this possible? Groeten, Joost Kraaijeveld Askesis B.V. Molukkenstraat 14 6524NB Nijmegen tel: 024-3888063 / 06-51855277 fax: 024-3608416 e-mail: J.Kraaijeveld@Askesis.nl web: www.askesis.nl
