If the "lo" field isn't NOT NULL than you should have no problem. The error message in your previous email came from trying to insert an integer into a text column. If you are still having problems please post your table definitions and the exact query that is causing trouble. -Doug ---------------------------(end of broadcast)--------------------------- TIP 6: Have you searched our list archives? http://archives.postgresql.org
