mysql如何删除HostName账号和localhost账号

语法: Delete from user where user = "user_name" and host = "host_name"

例子：delete from user where user='sss' and host='localhost'

或者： 取消一个账户和其权限

Drop USER user

drop user username@'%'

drop user username@localhost

删除所有的行:

delete * from tablename

删除指定的行:

delete * from tablename where colum_name=XXX

自带的？administrator吗？我的电脑右键，管理，用户和用户组，用户，administrator（或你自己期的名字），右键选择设置密码，密码为空，确定。 要删掉账号，你试试自己再创建一个管理员用户后，删除administrator
