Hi,  I am trying to write a case statement were I am comparing to dates to determine the result.  I do not think I am using the datediff function correctly.  I am hoping someone can take a look at my code and offer suggestions.

select
case
          when
            DATEDIFF(day, reportdate) - DATEDIFF(day,[Expected Close Date]) <=182)
            then '6 months'
          when DATEDIFF(day, reportdate) - DATEDIFF(day,[Expected Close Date])<=365)
          then '12 months
          else 'Rest'
        end as timeframe
from dbo.wkly_report

This works for me in SSMS 2012

Declare @report date = '1-1-2012', @close date = '8-1-2012'

SELECT 
	CASE 
	WHEN DATEDIFF(d, @report, @close) <= 182 THEN '6 months'
	WHEN DATEDIFF(d, @report, @close) <= 365 THEN '12 months' 
	ELSE 'Rest' END as timeframe
