我想把mysql数据库某个用户禁用掉，让这个用户无法登陆在哪设置

mysql 创建一个用户 hail，密码 hail，指定一个数据库 haildb 给 hail

mysql -u root -p

password

use mysql

insert into user(host,user,password) values('localhost','hail',password('hail'))

flush privileges

create database haildb

grant all privileges on haildb.* to hail@localhost identified by 'hail'

flush privileges

如果想指定部分权限给用户

grant select,update on haildb.* to hail@localhost identified by 'hail'

flush privileges

删除用户

delete from user where user='hail' and host='localhost'

flush privileges

删除用户数据库

drop database haildb

修改指定用户密码

update user set password=password('new_password') where user='hail' and host='localhost'

flush privileges

显示：“已经禁用删除数据库(DROP DATABASE)语句”

请教这是在哪里更改设置的？ show grants

贴出以供分析，怀疑用的不是 root@localhost 账号。先select user()

然后show grants for 第一步打印出来的用户和host；grant all privileges on *.* to root@'%' identified by "Passwd"！
