Question

我正在尝试以下查询，但它的输出是最后2周的数据，但我只需要在周数据之前持续。

select * from tablename where createddate>=DATEADD(WEEK,-2, GETDATE()) ;

Answer 1

只需在WHERE子句中添加另一个条件，将其限制为早于前一周的时间：

SELECT * FROM tablename
WHERE createddate >= DATEADD(WEEK,-2, GETDATE()) AND
      createddate < DATEADD(WEEK,-1, GETDATE())

Answer 2

从您的评论中我发现，您所谈论的那一周从星期五开始，所以您需要将这些差距天加入您的情况

SELECT * FROM tablename 
WHERE createddate >= DATEADD(ww, DATEDIFF(ww, 4 ,DATEADD(WEEK, -1, GETDATE())), 4)
AND createddate < DATEADD(ww, DATEDIFF(ww, 4 ,DATEADD(WEEK, 0, GETDATE())), 4)

Answer 3

此代码是我的定义的当前答案，

 select * from dbo_OrdersCompleteView1 where  S2_DateTimeOrederLines between DATEADD(WEEK,-2, GETDATE()) and DATEADD(WEEK,-1,GETDATE());

在sqlserver中如何查找前一周的数据？
