The-user-specified-as-a-definer-root-does-not-exist

最近从正式环境导入整个 db，查看 view 是提示

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

解析：
权限问题，授权 给 root 所有 sql 权限
解决方法：

mysql> grant all privileges on *.* to root@"%" identified by ".";
Query OK, 0 rows affected, 1 warning (0.00 sec)

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