SQL Server 2008 查询运行过去 8 周 [关闭]

Question

我有一个订单数据库。每个订单都包含一个输入日期。

我编写了一个查询，它返回 x 和 y 日期之间的订单......并且它有效。

但现在我需要为过去 8 周的每周编写查询。

所以首先应该在本周的星期日和星期六之间进行查询。应该能够确定本周的星期日是哪一天。

下一个查询应该查询上一周的周日到周六。

然后是上一个。

等等…………

然后我打算最后一起加入。

有什么想法吗？

我应该更清楚，这是我正在使用的查询。我需要运行 8 次.... 一个用于本周周日到周六..然后上一个等等。

选择 [订购日期]， COUNT(*) AS OrderTotal 来自 [订单] WHERE Order_Date 介于“2013/06/05”和“2013/06/11”之间 按 OrderComp 分组

Answer 1

不是我个人使用的版本，但应该是一个很好的通用日期表创建脚本。在谷歌搜索创建日期表后 2 秒内找到它。按周选择创建一个加入。

Answer 2

首先，您需要确定本周的星期日。为此，您需要以下代码

SELECT DATEADD(DAY, 1-DATEPART(WEEKDAY, GETDATE()), GETDATE())

现在，在您的查询中，将其设为 FROM 子句中的虚拟表

FROM ...,(SELECT DATEADD(DAY, 1-DATEPART(WEEKDAY, GETDATE()), GETDATE()) AS THIS_SUNDAY) SQ1

然后在您的 WHERE 子句中，您可以应用以下条件，这将为您提供前一周的订单。

ORDER DATE >= DATEADD(DAY,-7,SQ1.THIS_SUNDAY) AND ORDER DATE < SQ1.THIS_SUNDAY
