7 rows in set (0.00 sec)

# 将flow数据库所有权限赋给flowdba用户
mysql> grant all privileges on flow.* to 'flowdba'@'%';
Query OK, 0 rows affected (0.00 sec)
# 刷新权限
mysql> flush privileges;
Query OK, 0 rows affected (0.00 sec)

查看赋权结果：

mysql> use mysql;
# 表级的用户权限
mysql> select * from `db` where `user`='flowdba';
# 系统级的用户权限
mysql> select * from `user` where user='flowdba';
