You'll have to explain what you want n_gen to contain. Then you'll have to decide whether you want to do this in ASP where you can certainly change the SQL all you like, or on the server where you can have triggers which change the values being stored or executing additional queries. -- Gregory Stark EnterpriseDB http://www.enterprisedb.com Ask me about EnterpriseDB's PostGIS support! ---------------------------(end of broadcast)--------------------------- TIP 4: Have you searched our list archives? http://archives.postgresql.org
