Last Modified: 2012-05-10
Hello experts,

I need to group some data base of dates.  It needs to be grouped base on a weekly date.  See example.

Raw data:
ID      HOURS      DATE
8922      10.00      8/30/2010
8923      09.00      8/31/2010
8924      08.00      9/2/2010
8930      09.00      9/2/2010
8941      04.00      9/6/2010
8942      09.00      9/8/2010
8945      03.00      9/10/2010

Need to group it like the following:

ID      HOURS      DATE
8/30 - 9/3
8922      10.00      8/30/2010
8923      09.00      8/31/2010
8924      08.00      9/2/2010
8930      09.00      9/2/2010
9/6 - 9/10
8941      04.00      9/6/2010
8942      09.00      9/8/2010
8945      03.00      9/10/2010

You could try something like this: (not exactly what you were asking for)

select ID, Hours, Date, DATEPART(wk, Date) WeekNumber
from ....

or if you were summarizing by week, you could put

select sum(Hours) TotalHours, DATEPART(wk, Date) WeekNumber
from ....
group by DATEPART(wk, Date)
