Question

我有一个包含多个更新查询的字符串，示例：

$string = "UPDATE `student` SET `isams_id`=0001,`name`='stu name',`registration_id`='258911',`classid`=2,`section`='A',`house_name`='ELM',`status`=1,`updated_at`='2018-06-29 06:49:15' WHERE `registration_id`='258911'; UPDATE `student` SET `isams_id`=0002,`name`='xxx,`registration_id`='258912',`classid`=3,`section`='A',`house_name`='sss',`status`=1,`updated_at`='2018-06-29 06:49:15' WHERE `registration_id`='258912';"

像这样，我的字符串中大约有2500个更新查询。对于批量更新，我使用的是DB::update( DB::raw($string));。但这会返回错误，例如

SQLSTATE[42000]: Syntax error or access violation: 1064 You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'UPDATE `student` SET `isams_id`=0002,`name`='xxx',`registration_i' at line 1

如何解决此问题。请帮助我。

嘿，你可以这样

DB::update(DB::raw($string));

您还错过了一个单引号。应该是这样

$string = "UPDATE `student` SET `isams_id`=0001,`name`='stu name',`registration_id`='258911',`classid`=2,`section`='A',`house_name`='ELM',`status`=1,`updated_at`='2018-06-29 06:49:15' WHERE `registration_id`='258911'; UPDATE `student` SET `isams_id`=0002,`name`='xxx',`registration_id`='258912',`classid`=3,`section`='A',`house_name`='sss',`status`=1,`updated_at`='2018-06-29 06:49:15' WHERE `registration_id`='258912';"
