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

 Table_name: t3

  Timestamp: 0000-00-00 00:00:00
 Table_priv: Select
