依赖 SQL 子查询返回的行太少

Question

我有一个按商店划分的数百个品牌的销售额列表，我想按销售额获得每个商店排名前 100 的品牌。

不知什么原因，每家商店只退货 99 个品牌。 （来源表中，每家店铺900多个品牌。）

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？

我认为你想要做的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
