Question

我想创建一个视图，我想获得过去6个月内未售出的商品列表。我尝试了几种方法，但没有一种方法是正确的。请指导我。我有一个销售数据集市的表，其中包含项目号，我从另一个表中获取项目号，这是一个项目表，用于列出所有项目。这里有两种方法：我不能制作临时表，因为这是一个观点？

select distinct a.ItemID, a.TranDate Into #Itemslast6months 
from SalesDataMart a
where TranDate >= Dateadd(Month, Datediff(Month, 0, DATEADD(m, -6, current_timestamp)), 0)

Select distinct m.ITMNO_0 into #ItemsNotSoldLast6Months
from ITEMMASTER  as m
Where not exists (select ItemID
                    from #Itemslast6months as B
                    where m.ITMNO_0 = B.ItemID)


Select n.ITMNO_0, s.[Description], max(s.TranDate) last_Transaction_Date
from #temsNotSoldLast6Months n
join SalesDataMart s on n.ITMNO_0 = s.ItemID
group by n.ITMNO_0, s.[Description]

第二种方法：

 WITH ItemsSoldLast6Months (ItemID, TranDate)
      AS
      (
        select distinct a.ItemID, a.TranDate 
        from SalesDataMart a
        where TranDate >= Dateadd(Month, Datediff(Month, 0, DATEADD(m, -6, current_timestamp)), 0)

      )

  WITH ItemsNotSoldLast6Months (ItemNO)
      AS
      (
      Select distinct m.ITMNO_0 
from ITEMMASTER  as m
Where not exists (select ItemID
                    from ItemsSoldLast6Months as B
                    where m.ITMNO_0 = B.ItemID)

    )


Select n.ITMNO_0, s.[Description], max(s.TranDate) last_Transaction_Date
from #temsNotSoldLast6Months n
join SalesDataMart s on n.ITMNO_0 = s.ItemID
group by n.ITMNO_0, s.[Description]

Answer 1

这个似乎是您正在寻找的东西，但如果没有样本数据集或表中的DDL，很难说清楚。

Select distinct 
    m.ITMNO_0, 
    s.[Description], 
    max(s.TranDate) last_Transaction_Date
from ITEMMASTER  as m
join SalesDataMart s on m.ITMNO_0 = s.ItemID
Where not exists (  select distinct a.ItemID 
                    from SalesDataMart a
                    where a.TranDate >= Dateadd(Month, Datediff(Month, 0, DATEADD(m, -6, current_timestamp)), 0))
group by m.ITMNO_0, s.[Description]

Answer 2

假设您的商品表是ItemMaster且销售交易在SalesDataMart中，您的查询将如下所示。

SELECT *
FROM    ITEMMASTER AS m
WHERE   NOT EXISTS ( SELECT ItemID
                     FROM   SalesDataMart AS S
                     WHERE  m.ITMNO_0 = S.ItemID
                            AND TranDate > DATEADD(MONTH, -6, GETDATE())
                   );

如果某件商品在过去6个月内售出，则会从ItemMaster上的查询中过滤掉

sql查看过去6个月内未售出的商品
