MySQL查看用户权限命令的两方法:

一. 使用MySQL grantsmysql> 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)

二. 直接通过mysql select查询语句:mysql> select * from mysql.user where user='test' and host='127.0.0.1' \G;

*************************** 1. row ***************************

Host: 127.0.0.1

User: test

Password: *EB3C643405D7F53BD4BF7FBA98DCF5641E228833

1 row in set (0.00 sec)

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
