MySQL的通过成绩排名的用户/分

Question

下面的查询凉对于普通用户按分数排名次，但我需要在表中同分同等级结果的查询

SET @rank = 0; 
SELECT * FROM (
    SELECT @rank:=@rank + 1 AS rank,score, user_id FROM site_crossword_members ORDER BY score DESC 
) as tmp; 

感谢

Answer 1

你确定你的给定查询甚至可以正常工作我记得ORDER BY要在SELECT之后完成，因此使您的排名按ID ASC排序或类似。

SELECT user_id, 
    CASE WHEN @score != score THEN @rank := @rank + 1 ELSE @rank END AS rank, 
    @score := score AS dummy_value 
FROM ( SELECT score, user_id 
     FROM site_crossword_members, 
      (SELECT @rank := 0, @score := NULL) AS vars 
     ORDER BY score DESC) AS h 

缩短版本：

SELECT user_id, 
    @rank := @rank + (@score != score) AS rank, 
    @score := score AS dummy_value 
FROM ( SELECT score, user_id 
     FROM site_crossword_members, 
      (SELECT @rank := 0, @score := NULL) AS vars 
     ORDER BY score DESC) AS h

尝试此查询（用变量版本） -

SET @rank = 0; 
SET @score = NULL; 

SELECT 
    rank, score, user_id 
FROM (
    SELECT 
    score, 
    user_id, 
    IF(@score = score, @rank := @rank + 1, @rank := 1) AS rank, 
    @score := score 
    FROM site_crossword_members 
    ORDER BY score DESC 
) t;
