mysql - 反转分组查询的序列号

Question

以下查询根据用户投票的次数来排序投票...我想知道特定用户队列中的#。

SELECT @s:=@s+1 serial_number, user_id, COUNT(slug_owner) as cnt 
FROM `votes_queue`,(SELECT @s:= 0) AS s 
GROUP BY slug_owner
ORDER BY cnt DESC 

serial_number | user_id | cnt 
3 | 19 | 8
2 | 14 | 4
1 | 13 | 2

基本上我需要反转 serial_number 列中的数字，这样我就可以根据投票判断用户 13 是#3 ..

Answer 1

生成有序计数后分配序列号:

SELECT @s:=@s+1 serial_number, temp.*
FROM (
    SELECT user_id, COUNT(slug_owner) as cnt 
    FROM `votes_queue`,
    GROUP BY slug_owner
    ORDER BY cnt DESC
) temp, (SELECT @s:= 0) AS s
