My query looks like below , every thing works fine . Only I need in Sep 2014 I need Total ( instead of 2 should be 81) .
Select 'Reports' AS ReportName,
datepart(month,Date) [mn],
datepart(year,Date) [yr],
datename(month,max(Date))+' '+convert(varchar(4),datepart(year,max(Date))) [Month],
Count(ReportName)[CountReports]
from DB.dbo.Table1
group by datepart(month,Date),datepart(year,Date)
ReportName      mn         yr            Month                   
CountReports
Reports          8        2014       August 2014

Answer 1

That was an example which I have posted to illustrate how to get a running count within groups .
I've made some assumptions on your table schema, based on the query you have posted.
Here you go
drop table #temp
 create table #temp
 (ReportName varchar(30),
 [Date] datetime
insert into #temp values ('rep1','1-jan-2014')
insert into #temp values ('rep2','2-jan-2014')
insert into #temp values ('rep3','1-jan-2014')
insert into #temp values ('rep4','1-feb-2014')
insert into #temp values ('rep6','1-feb-2014')
insert into #temp values ('rep6','1-feb-2014')
insert into #temp values ('rep6','1-Mar-2014')
insert into #temp values ('rep6','1-April-2014')
insert into #temp values ('rep6','1-Dec-2014')
insert into #temp values ('rep6','1-Nov-2014')
 ;WITH g AS
   SELECT datepart(month,Date) [mn],
datepart(year,Date) [yr],
 count(reportname) as cnt
     FROM #temp
     GROUP BY datepart(year,Date) ,Datepart(month,[Date])
 SELECT 'Reports' name,mn,yr,
   countreports = SUM(cnt) OVER (ORDER BY yr,mn ROWS UNBOUNDED PRECEDING)
 FROM  g
 ORDER BY yr,mn
Hope this helps!!
