我有一个订单数据库。每个订单都包含一个输入的日期。
我写了一个查询，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........
然后我计划最终加入。
有任何想法吗？
我应该更清楚，这是我正在使用的查询。我需要运行这 8 次.... 一个为本周周日坐..然后上一个，依此类推。
SELECT [OrderDate], COUNT(*) AS OrderTotal FROM [Orders] WHERE Order_Date between '2013/06/05' AND '2013/06/11' group by OrderComp
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。

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条款中，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
