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_priv\G;
*************************** 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

[root@mysql ~]# mysql -umike -p123
