Refining a pivot table Monthly to Quarterly

Hello,
I have the following query:

select *
  from
  (
      SELECT
       [Custnum]
      ,[Custname]
      ,period,amount
     
      ,[Inventory code]

                                    
       FROM [VisionTools].[dbo].[SupplySalesEAUTOOMD]
       ) x
  PIVOT (SUM(Amount) FOR PERIOD IN ([201201],[201202],[201203],[201204]
                                                      ,[201205],[201206],[201207],[201208],[201209],[201210],[201211],[201212],[201301]
                                                      ,[201302],[201303],[201304],[201305],[201306],[201307],[201308],[201309],[201310],[201311],[201312])) P
      WHERE  [INVENTORY CODE] LIKE 'SUPINK'
      ORDER BY [Custname]

and partial result is seen in attachment.
What I need is to sum and group the months into quarterly columns. not month by month .

If you could point me in the right direction.

THank you

assuming you follow the January - December year you need to do two things:

select *
  from
  (
      SELECT
       [Custnum]
      ,[Custname]
      ,period
      ,amount      
      ,[Inventory code]
      --create case statement for quarter
      ,case when month(period) between 1 and 3 then 1
              when month(period) between 4 and 6 then 2
              when month(period) between 7 and 9 then 3
              when month(period) between 10 and 12 then 4
        EMD Quarter

                                   
       FROM [VisionTools].[dbo].[SupplySalesEAUTOOMD]
       ) x
--update pivot.
PIVOT (SUM(Amount) FOR Quarter IN (1,2,3,4) P
      WHERE  [INVENTORY CODE] LIKE 'SUPINK'
      ORDER BY [Custname]

The only thing you would need to do is convert your Period column in a value that represents how you want to display your Quarters.

Something like:
LEFT(CAST([period] AS VARCHAR), 4) + 
CASE RIGHT(CAST([period] AS VARCHAR), 2)
    WHEN '01' THEN 'Q1'
    WHEN '02' THEN 'Q1'
    WHEN '03' THEN 'Q1'
    WHEN '04' THEN 'Q2'
    WHEN '05' THEN 'Q2'
    WHEN '06' THEN 'Q2'
    WHEN '07' THEN 'Q3'
    WHEN '08' THEN 'Q3'
    WHEN '09' THEN 'Q3'
    WHEN '10' THEN 'Q4'
    WHEN '11' THEN 'Q4'
    ELSE 'Q4' END As QuarterPeriod
 

Then change your PIVOT to be over QuarterPeriod instead of Period, and change the columns you want to see in your results (i.e. 2012Q1, 2012Q2, etc.)

btw. I didn't mention it but the column "period" is a float.

Kyle AbrahamsSenior .Net DeveloperCommented:
There's a slight typo . . . "EMD" should be "END".  What does period represent?  You can always cast it as a datetime

eg:

case when month(cast (period as smalldatetime)) between 1 and 3 then 1
-- update the rest.

I just did a right(period,2)  and that works

I didn't however mention that I still need separation between years.
We need these numbers to compare quarterly sales form year to year.

select *
  from
  (
      SELECT
       [Custnum]
     
      ,period
      ,amount      
      ,[Inventory code]
      --create case statement for quarter
      ,case when right(period,2) between 1 and 3 and Left(period,4) = '2012' then '2012-Q1'
              when right(period,2) between 4 and 6 and Left(period,4) = '2012' then '2012-Q2'
              when right(period,2) between 7 and 9 and Left(period,4) = '2012' then '2012-Q3'
              when right(period,2) between 10 and 12 and Left(period,4) = '2012' then '2012-Q4'
             
              when right(period,2) between 1 and 3 and Left(period,4) = '2013' then '2013-Q1'

              when right(period,2) between 10 and 12 and Left(period,4) = '2013' then '2013-Q4'
