  • mysql 权限管理 针对某个库 某张表 授权 tables_priv表

    精确到表级别

    针对db1的t3表 授予select权限

    mysql> grant select on db1.t3 to 'mike'@'localhost';
    Query OK, 0 rows affected (0.07 sec)

    验证

     #只在tables_priv表中可以查到mike用户的select权限
    mysql> select * from mysql.tables_privG;
    *************************** 1. row ***************************
           Host: localhost
             Db: db1
           User: mike
     Table_name: t3
        Grantor: root@localhost
      Timestamp: 0000-00-00 00:00:00
     Table_priv: Select
    Column_priv: 
    1 row in set (0.00 sec)
    
    ERROR: 
    No query specified

    验证

    mysql> exit
    Bye
    [root@mysql ~]# mysql -umike -p123

    只能看到db1库下面的 t3表 看不到t1表,只放行对t3表查询
