Could you provide a complete test case? Works fine here: CREATE TABLE pidtest (pid integer, szoveg text) WITHOUT OIDS; INSERT INTO pidtest (pid, szoveg) VALUES (3, 'three'); INSERT INTO pidtest (pid, szoveg) VALUES (4, 'four'); INSERT INTO pidtest (pid, szoveg) VALUES (5, 'five'); INSERT INTO pidtest (pid, szoveg) VALUES (6, 'six'); INSERT INTO pidtest (pid, szoveg) VALUES (7, 'seven'); SELECT pid FROM pidtest WHERE pid > 5 FOR UPDATE; pid ----- 6 7 (2 rows) SELECT * FROM pidtest; pid | szoveg -----+-------- 3 | three 4 | four 5 | five 6 | six 7 | seven (5 rows) -- Michael Fuhr http://www.fuhr.org/~mfuhr/ ---------------------------(end of broadcast)--------------------------- TIP 1: if posting/reading through Usenet, please send an appropriate subscribe-nomail command to [EMAIL PROTECTED] so that your message can get through to the mailing list cleanly
