revoke create,drop,alter 失败？

Question

我的mysql版本是5.5.8社区版revoke create on *.* from 'csfdp'@'%';
revoke drop on *.* from 'csfdp'@'%';
revoke alter on *.* from 'csfdp'@'%';
用root用户执行以上命令之后，提示执行成功。接着用csfdp登录，发现还能执行以下create、drop操作？
create table test.t select 1 as id;
drop table test.t;
这是怎么回事？难道我的revoke命令写错了？

Answer 1

我这里没问题你去看下mysql.user表的对应权限是否已经是N

Answer 2

贴出你的select  * from mysql.user\G;

Answer 3

putte的窗口里面用\G显示不了全部数据。

Answer 4

mysql> mysql> select * from mysql.user limit 5 \G;

Answer 6

难道revoke也需要flush privileges?

Answer 7

或者有两个以上的csfdp用户，不同的host？
select * from mysql.user where user='csfdp';

Answer 8

没有，只有一个csfdp账号的。

Answer 9

我也很纳闷啊，悲剧了，难道是我的revoke语句出错了吗？

Answer 10

show grants;'GRANT SELECT, INSERT, UPDATE, DELETE ON *.* TO ''csfdp''@''%'' IDENTIFIED BY PASSWORD ''*B13D3DA1A8037763ED485FDFD0C966C22114971E'''
'GRANT SELECT, INSERT, UPDATE, DELETE, CREATE TEMPORARY TABLES, LOCK TABLES, EXECUTE, SHOW VIEW ON `um`.* TO ''csfdp''@''%'''

Answer 11

delete from mysq.user where name='csfdp';
flush privilege;
grant all on *.* to 'csfdp'@'%' IDENTIFIED BY '123';
