mysql排序与一个不唯一的排名？

Question

可能重复：
How do I Handle Ties When Ranking Results in MySQL?

我想用Activepoints订购表Status并插入到秩一列rank。 它配备：

RANK USERNAME ACTIVEPOINTS 

1  monkey100  92 
2  fresnoJump 54 
3  otherUser9 54 

，但它应该显示不是唯一的行列像

RANK USERNAME ACTIVEPOINTS 

1  monkey100  92 
2  fresnoJump 54 
2  otherUser9 54 

Answer 1

我认为这是解决了2个UDF变量http://dev.mysql.com/doc/refman/5.0/en/user-variables.html。

SET @rank = 0, @previous_active_points = 0; 
SELECT IF(@previous_active_points<>Activepoints,@rank:=@rank+1,@rank) AS rank, 
@previous_active_points:=Activepoints,username,Activepoints 
FROM `status` ORDER BY Activepoints 

希望它有帮助！
