MySQL5.6导入数据时的错误分析

Posted 2020-06-26

今天在导入mysqldump导出的数据的时候出现了一个奇怪的错误？

ERROR 1064 (42000) at line 13327: 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 ‘*/‘ at line 1

打开文件的13327行，发现这个是一个触发器的SQL语句带有 /*! */ 不仔细看以为创建triggers失败

但是手工执行的时候确实这样子的：

mysql> /*!50003 CREATE*/ /*!50017 DEFINER=`appuser`@`%`*/ /*!50003 TRIGGER `b_admin_user_update` AFTER UPDATE ON `b_admin_user` FOR EACH ROW

    ->       INSERT INTO delta_b_admin_user(`user_id`,`username`, `password`, `salt`, `real_name`, `cell_phone`, `qq`, `phone`, `email`, `wangwang`, `created_time`, `last_login_time`, `last_login_ip`, `user_group_id`, `flag`, `parent_id`, `qr_code`)

    -> values

    -> (NEW.user_id,NEW.username, NEW.password, NEW.salt, NEW.real_name, NEW.cell_phone, NEW.qq, NEW.phone, NEW.email, NEW.wangwang, NEW.created_time, NEW.last_login_time, NEW.last_login_ip, NEW.user_group_id, NEW.flag, NEW.parent_id, NEW.qr_code); */;;

Query OK, 0 rows affected (0.01 sec)

ERROR 1064 (42000): 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 ‘*/‘ at line 1

这是执行成功了呢？ 但还是报了个错误：（

经过查找，发现mysql在导入的时候有个参数是忽略错误继续执行后面的SQL知道整个文件执行完成

--force 这个参数，加上参数再导入一次

/usr/local/mysql-5.6/bin/mysql -uroot -p‘pass‘ --force  < /usr/local/mysql-5.6/all.sql

恩，确实没有退出。

之后又做了一个测试

在导出数据的时候不导出触发器，那么需要加上参数 --skip-triggers

再导入的时候就没有报错了

那么是不是mysql-5.6版本的关系么？

有待研究
