Question

我有一个商店的数百个品牌的销售清单，我想通过销售获得每个商店的100个品牌。

由于某些未知原因，每家商店仅返回99个品牌。（在源表中，每个商店有超过900个品牌。）

这是我的疑问：

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

出了什么问题？

我认为您尝试做的事情可以通过以下查询来实现

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

依赖SQL子查询返回的行太少
