此腳本一直工作正常2年。我在活動表中刪除了超過2000行，可能它太大了？MAX_JOIN_SIZE行; SET SQL_BIG_SELECTS = 1 - 腳本在2年後停止工作

你在哪裏添加了'SQL_BIG_SELECTS = 1'？ – junkfoodjunkie

第一行 'code' $ bisql =「SET OPTION SQL_BIG_SELECTS = 1」; try { \t $ dbh-> setAttribute（PDO :: ATTR_ERRMODE，PDO :: ERRMODE_EXCEPTION）; $ dbh-> setAttribute（PDO :: ATTR_EMULATE_PREPARES，false）; \t $ bistmt = $ dbh-> prepare（$ bisql）; \t $ bistmt-> execute（array（））; （例外$ e）{ echo'Exception - >'; var_dump（$ e-> getMessage（））; } 'code' –

我想你在調用生成代碼時需要將它設置爲一個選項。嘗試讀這：http://stackoverflow.com/questions/34853129/how-to-set-sql-big-selects--1-la-ravel-join-statement – junkfoodjunkie

交換

SET OPTION SQL_BIG_SELECTS=1

到

SET SESSION SQL_BIG_SELECTS=1

現在，它的工作！
