MySQL查看用户权限命令的两方法:
MySQL grant详细用法见: mysql grant使用方法 :
mysql> show grants for username@localhost;
实例:
mysql> show grants for root@localhost;
+---------------------------------------------------------------------+
| Grants for root@localhost |
+---------------------------------------------------------------------+
| GRANT ALL PRIVILEGES ON *.* TO 'root'@'localhost' WITH GRANT OPTION |
+---------------------------------------------------------------------+
1 row in set (0.01 sec)
mysql> select * from mysql.user where user='test' and host='127.0.0.1' G;

可以看到Select_priv,Insert_priv,Update_priv…等为N表示没有权限,该用户权限一目了然.这时可以使用命令
给用户加权限:
grant all privileges on *.* to 'test'@'127.0.0.1' identified by 'passwd';
flush privileges;
另外:show可以看到很多东西:
show databases;
show tables;
show create database dbname; // 这个可以看到创建数据库时用到的一些参数。
show create table tablename; // 可以看到创建表时用到的一些参数
