我上面的表格包括日期和活动。现在我想编写脚本，我可以在每周找到新的活动。例如：我本周有10个活动，下周还会有另外2个活动。所以，那些2将是新的，并且想要编写脚本以在每周基础上以下面的格式找到新活动;

本周将从星期日开始。

----------------------------------------------------------------

2013-09-08         2013-09-14         Mobile                 37
2013-09-08         2013-09-14         Reservation            37

我想创建这种格式，您可以看到第37周有一项新活动来电预订。我想设置自动化流程来每周捕获这些新活动。

我只想猜你是如何得到你想要的OUPUT中的活动专栏那么这就是我要做的事情....

测试数据

DECLARE @TABLE TABLE( Conversiondate DATETIME,Activity VARCHAR(400))
INSERT INTO @TABLE VALUES
('2013-09-30 00:00:00','Renaissance_Homepage_022013'),
('2013-09-12 00:00:00','RFP - Total'),
('2013-09-23 00:00:00','Reservations Rate List Menu'),
('2013-09-08 00:00:00','SHS 2.0 Home'),
('2013-09-17 00:00:00','MR Promo Registration Confirmation'),
('2013-09-13 00:00:00','Renaissance_ReservationOverlay_022013'),
('2013-09-02 00:00:00','Reservations Rate List Menu'),
('2013-09-13 00:00:00','Renaissance_HotelPage_022013'),
('2013-09-08 00:00:00','Reservations Rate List Menu')

<强>查询

SELECT   CAST(DATEADD(dd, -(DATEPART(dw, Conversiondate)-1)
                         , Conversiondate) AS DATE) [WeekStart]
        ,CAST(DATEADD(dd, 7-(DATEPART(dw, Conversiondate))
                          , Conversiondate) AS DATE) [WeekEnd]
        ,  Activity
        ,DATEPART(WEEK, Conversiondate) [Week_Number]
