mysql 1449 ： The user specified as a definer ('usertest'@'%') does not exist 解决方法 (grant 授予权限)

从服务器上迁移数据库到本地localhost

执行  函数  时报错，

mysql 1449 ： The user specified as a definer ('usertest'@'%') does not exist

经查，是权限问题(其中usertest是服务器上数据库的登录名)，解决办法：

授权给 usertest 所有sql 权限

mysql> grant all privileges on *.* to usertest@"%" identified by ".";
Query OK, 0 rows affected (0.00 sec)

mysql> flush privileges;
Query OK, 0 rows affected (0.00 sec)
