php - mysql按分数/点数对用户进行排名

Question

下面的查询对于按分数排名的普通用户来说很酷，但我需要一个具有相同排名结果的查询，以获得表中相同的分数

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

谢谢

您确定您给定的查询是否正常工作？我记得要在 SELECT 之后完成 ORDER BY，从而使您的排名按 ID ASC 或类似方式排序。

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

简化版:

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
