问题 following query returns all wanted results if entered in phpmyadmin: SELECT postid, voting FROM postvotes WHERE userid = 1 AND postid IN (1007,1011,1012,1013,1014, 1015,1016,1017,1018,1019,1020,1021,1023,1025,1026, 1027,1028,1029,1030,1031) But PDO fails to fetchAll().

PHP Code: private function userPostVotings( $postIDs ) { // $postIDs contains a string like 1,2,3,4,5,6,7... // generated through implode(',', idArray) try {

问题 I have developed a system using an OR query: SELECT * FROM tableA JOIN tableB ON (idA = idB) WHERE idA = 1 OR idA = 2 OR idA = 3 OR idA = 4 OR idA = 5 ......
