Maybe something like this will help: SELECT id FROM generate_series(1, (SELECT last_value FROM id_seq)) AS s(id) EXCEPT SELECT UniqIntId FROM MyDataTable ORDER BY id; The id_seq is the sequence on your ID column, assuming it has one, or you can replace the (SELECT ... FROM id_seq) by 1000. Joe ---------------------------(end of broadcast)--------------------------- TIP 4: Have you searched our list archives? http://archives.postgresql.org
