执行 grant all privileges on *.* to root@"%" identified by "." 也报错

mysql> grant all privileges on *.* to root@"%" identified by ".";

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 'identified by "."' at line 1

最终解决办法：

执行sql语句：

　　GRANT ALL PRIVILEGES ON database_name.* to 'root'@'localhost';

　　FLUSH   PRIVILEGES;

存储过程中 definer修改为：root@localhost
