Question

如何获取表格中特定值的行号？这只会导致第1行，我知道这是因为我只返回1行，但我该怎么办呢？

我想知道特定用户与整个表相比的“等级”，所以我希望返回数据如下：

Rank    UserId
 326    c7f3b047-b5ee-4619-a409-8ff7b29179f8

查询：

DECLARE @UserId uniqueidentifier
SET @UserId='c7f3b047-b5ee-4619-a409-8ff7b29179f8'

SELECT 
    ROW_NUMBER() OVER (ORDER BY Ratio desc) AS 'Rank', 
    ROW_NUMBER() OVER (ORDER BY RatioMonth desc) AS 'RankMonth', 
    ROW_NUMBER() OVER (ORDER BY RatioWeek desc) AS 'RankWeek', 
    UserMessData.UserId, 
    aspnet_Users.UserName, 
    Wins, Losses, Ratio, 
    WinsMonth, LossesMonth, RatioMonth, 
    WinsWeek, LossesWeek, RatioWeek 
FROM 
    UserMessData 
JOIN 
    aspnet_Users ON aspnet_Users.UserId = UserMessData.UserId
WHERE 
    UserMessData.UserId IN (@UserId)
ORDER BY 
    'Rank' ASC

请帮忙！

您必须在整个列表中找到用户的位置，然后过滤：

DECLARE @UserId uniqueidentifier
SET @UserId='c7f3b047-b5ee-4619-a409-8ff7b29179f8'

select *
from
(
    SELECT ROW_NUMBER() OVER (ORDER BY Ratio desc) AS 'Rank', 
    ROW_NUMBER() OVER (ORDER BY RatioMonth desc) AS 'RankMonth', 
    ROW_NUMBER() OVER (ORDER BY RatioWeek desc) AS 'RankWeek', 
    UserMessData.UserId, 
    aspnet_Users.UserName, 
    Wins, Losses, 
    Ratio, 
    WinsMonth, 
    LossesMonth, 
    RatioMonth, 
    WinsWeek, 
    LossesWeek, 
    RatioWeek FROM UserMessData 
    JOIN aspnet_Users ON aspnet_Users.UserId=UserMessData.UserId
) a
WHERE a.UserId IN (@UserId)
