You want the dateadd function:

http://technet.microsoft.com/en-us/library/ms186819.aspx

Where reportdate between getdate() and dateadd(dd, getdate(), -14)

Open in new window


Should do the trick - between "now" and "14 days ago"

Select 06-07, 07-08, 08-09
from UsageLogs
where BranchId = 54
      AND reportDate between cast(getdate() - 14 as date) and cast(getdate() as date)

Basically you wan all the records from the table that have a ReportDate in the last 14 days from right now, which means the ReportDate is greater than right now minus 14 days:
Select 
	06-07, 07-08, 08-09 
from 
	UsageLogs 
where 
	BranchId = 54 
	AND reportDate > DATEADD(dd,-14, getdate())

Hi Folks

I fear that the results will be something like
-1, -1, -1.

I suggest that if those really are columns names that you'll need to quote them, say with square brackets.

select
    [06-07]
    , [07-08]
    , [08-09]

etc.

Here is a pivot table that sort of does something similar
select 
	pvt.SystemDrive
	, pvt.Environment
	, pvt.BusinessDescription
	, [0], [1], [2], [3], [4], [5], [6], [7], [8], [9]
	, [10], [11], [12], [13], [14], [15], [16], [17], [18], [19]

Points of interest:
I'm calculating days ago. Today is 0 days ago, yesterday is 1 day ago, etc. That means that the column headings 0, 1 ...199 _always_ work for me, and I don't have to do any dynamic stuff to label the columns.

That is, next week, your column headings will all be different, and so you can't use this weeks query ...

I'm pre-selecting servers of interest into #t

There could be one or more rows in servers which have the same machine name/system name. That is, I'm allowing for multiple instances of SQL on servers.
