869      1      1      2      NULL      39.00      36.00      33.00

873      2      3      NULL   NULL      50.00      50.00      50.00

产品ID有4条记录我想在表中找到最低销售价格记录。例如
产品ID = 1 结果是：

869 1   1   2   NULL    39.00   36.00   33.00

请帮帮我

Answer 1

如果出现平局，以下内容将返回多行。如果您不希望使用Row_number()代替Rank()

;WITH cte AS
     ( SELECT  ProductPriceId,
              ProductId      ,
              CurrencyId     ,
              CustomerGroupId,
              PriceTierId    ,
              List           ,
              Selling        ,
              Bulk           ,
              RANK() OVER (PARTITION BY ProductId ORDER BY Selling) AS Rnk
     FROM     ProductPrice
     )
SELECT ProductPriceId ,
       ProductId      ,
       CurrencyId     ,
       CustomerGroupId,
       PriceTierId    ,
       List           ,
       Selling        ,
       Bulk
FROM   cte
WHERE  Rnk=1

Answer 2

SELECT TOP 1 
    * 
FROM 
    ProductPrice 
WHERE 
    ProductId = 1 
ORDER BY 
    Selling ASC

Answer 3

select t1.*
from ProductPrice t1
where not exists(select *
                 from ProductPrice t2
                 where t2.Selling<t1.Selling and t2.productid=t1.priductid)

这将返回每个产品ID的所有最低销售价格记录。如果有多个这样的行，那么它将返回多个。

您可以使用以下查询来查找所需的结果。

SELECT  ProductPriceId, ProductId, CurrencyId, CustomerGroupId, PriceTierId, List, Selling, Bulk,

        RANK() OVER (PARTITION BY ProductId ORDER BY Selling DESC) AS Rnk

FROM    ProductPrice

WHERE  Rnk=1
