Use its min_value >instead. OK. Given the discussion of 'select nextval', do you know if 'select setval' will set the is_called flag? If not should I: Issue 'CREATE SEQUENCE...Initial Value <MINVAL>...' in OID order if (is_called was set AND we've loaded any data) then Issue 'SELECT NEXTVAL...' at end of data load, and *before* setval. Issue 'SELECT SETVAL...' at end of data load. endif ---------------------------------------------------------------- Philip Warner | __---_____ Albatross Consulting Pty.
