相關的SQL子查詢返回的行數太少

Question

我有一個商店的數百個品牌的銷售清單，我希望通過銷售獲得每個商店排名前100的品牌。

由於某些未知原因，每個商店僅返回99個品牌。 （在源表中有每每家店鋪超過900個品牌。）

這是我的查詢：

SELECT TOP (100) PERCENT SHOP, BRAND, SALES 
FROM dbo.[DATA] AS D 
WHERE (BRAND IN 
    (SELECT TOP (100) WITH TIES BRAND 
     FROM DATA 
     WHERE (SHOP= D.SHOP) 
     ORDER BY SALES DESC 
    ) 
) 
ORDER BY BRAND, SALES DESC 

出了什麼問題？

我想你正在嘗試做的可以通過下面的查詢來實現

SELECT Q.SHOP 
    , Q.BRAND 
    , Q.SALES 
FROM (
    SELECT SHOP 
     , BRAND 
     , SALES 
     , ROW_NUMBER() OVER (PARTITION BY SHOP ORDER BY SALES DESC) rn 
    FROM dbo.[DATA] 
    ) Q 
WHERE Q.rn <= 100 
ORDER BY Q.BRAND, Q.SALES DESC
