需求 只放行user表 db1库的select权限
mysql> grant select on db1.* to 'mike'@'localhost'; Query OK, 0 rows affected (0.05 sec)
查看有没有记录
mysql> select * from mysql.dbG;
db1这个库下的所有表都可以查看select
mysql> exit Bye [root@mysql ~]# mysql -umike -p123 Warning: Using a password on the command line interface can be insecure. Welcome to the MySQL monitor. Commands end with ; or g.
