mysql查询获取特定记录

Question

我正在做各种排名表，需要从查询中找到特定的行位置。

例如：     SELECT name FROM players ORDER BY points DESC

如何使用“John”的name字段或任何其他字段获取记录的位置？

所以我希望结果给我一个数字（'John'的等级）

Answer 1

SET @rank=0;
SELECT @rank:=@rank+1 AS rank, name 
  FROM players ORDER BY points DESC

或

SELECT @rn:=@rn+1 AS rank, name
FROM (
  SELECT name 
      FROM players ORDER BY points DESC
) t1, (SELECT @rn:=0) t2;
