mysql权限问题

数据库报错：

The user specified as a definer (‘root’@’%’) does not exist

权限问题，授权 给 root 所有sql 权限

进入mysql命令：mysql -uroot -p密码

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

mysql> flush privileges;

Query OK, 0 rows affected (0.00 sec)

迁移数据库后，调用存储过程出错了
Error: ER_NO_SUCH_USER: The user specified as a definer (‘root’@’%%’) does not exist

先创建root@"%%“账户：mysql> create user root@”%%";
Query OK, 1 row affected (0.06 sec)

之后再调用存储过程报错：
Error: ER_PROCACCESS_DENIED_ERROR: execute command denied to user ‘root’@’%%’ for routine ‘hgtdatabase.resetPsw’

给root@"%%"权限，mysql>GRANT ALL PRIVILEGES ON . TO ‘root’@’%%’;
Query OK, 0 rows affected (0.01 sec)。
