How do I Handle Ties When Ranking Results in MySQL?
我想按 Activepoints 对表 Status 进行排序，并将排名插入列 rank 中。
它来了:
RANK USERNAME ACTIVEPOINTS
1 monkey100 92
2 fresnoJump 54
3 otherUser9 54
但它应该显示的不是唯一的排名
RANK USERNAME ACTIVEPOINTS
1 monkey100 92
2 fresnoJump 54
2 otherUser9 54
最佳答案
我认为这可以通过 2 个 UDF 变量解决 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
希望对您有所帮助!
关于mysql order by 不是唯一的等级？，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/7905789/
