When I join cls1 with subcls1 tables(from cls1 to cls20 and subcls1 to subcls20) and union these 40 tables toghther. It's work. In the same condition, when I try to join and union 120 tables(three times as previous case) together, it can't work. At that moment, I use strlen() try to figure out the length of the query string, the len is 33817. Doesn't is a bug or does there have any system paramater that I need to change? I appreciated. Reproduce code: --------------- select StsID, count(*) from ( SELECT * FROM ( SELECT cls.ID, cls.IIGrpID, cls.IIID , subcls.* FROM cls1 AS cls LEFT JOIN ( SELECT AIID, ID, StsID, CIGrpID, CIID, RIGrpID, RIID FROM subcls1 as subcls ORDER BY StsID ) AS subcls ON cls.ID = subcls.AIID GROUP BY cls.ID ) whole LEFT JOIN ( SELECT count( * ) AS num FROM subcls1 as subcls GROUP BY AIID ) AS subsum ON whole.ID = subsum.AIID UNION …… UNION SELECT * FROM ( SELECT cls.ID, cls.IIGrpID, cls.IIID , subcls.* FROM cls60 AS cls LEFT JOIN ( SELECT AIID, ID, StsID, CIGrpID, CIID, RIGrpID, RIID FROM subcls60 as subcls ORDER BY StsID ) AS subcls ON cls.ID = subcls.AIID GROUP BY cls.ID ) whole LEFT JOIN ( SELECT count( * ) AS num FROM subcls60 as subcls GROUP BY AIID ) AS subsum ON whole.ID = subsum.AIID ) as whole group by StsID Expected result: ---------------- I can got each status total number from the result. Actual result: -------------- StsID count(*) 1 6800 2 2600 3 4600 4 6200 5 3800 ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=39470&edit=1
