MySql排名查询

1.新建一张成绩表

-- 新建成绩表
CREATE TABLE IF NOT EXISTS `score` (
  `id` int(11) NOT NULL AUTO_INCREMENT,
  `name` varchar(32) NOT NULL DEFAULT '',
  `scores` int(11) NOT NULL DEFAULT '0',
  PRIMARY KEY (`id`)
) ENGINE=MyISAM  DEFAULT CHARSET=utf8 AUTO_INCREMENT=6 ;

-- 插入学生成绩
INSERT INTO `score` (`id`, `name`, `scores`) VALUES
(1, 'a', 97),
(2, 'b', 90),
(3, 'c', 98),
(4, 'd', 97),
(5, 'e', 66);

2.查询成绩排名

select * from
(
    select (select count(id)+1  from score where scores>a.scores) as mc,a.name,a.scores
    from score a
) b where b.mc<=10 
order by b.mc;

查询结果如下：
