>create 24 month total cte's
Without digging into your T-SQL, copy-paste the below code into your SSMS, execute it to verify it works, and modify to meet your needs:
CREATE TABLE #tmp (dt date) 

Declare @x int = 0, @dt date = CAST(GETDATE() as date) 

WHILE @x < 24
   begin

   INSERT INTO #tmp (dt) 
   SELECT DATEADD(month, @x, @dt) 

   SET @x = @x + 1

   end

SELECT * FROM #tmp

I mean I dont see efficient coding to create the below 24 times to get the final output

MONTH_1 AS (
select
nsn,
sum(qty_required) as month1_total
from d_item1, dual
where date_create >= sdate and date_create < sdate2
and status between '01' and '79'

Hello Scott is there a way to tell the Month and year for month1, month2..instead say March 2014,April 2014,May 2014....

Do you mean is there a way to have column headings of "March 2014" instead of "Month1"?

If that is what you mean than this is much more difficult and you need to create "dynamic sql" (i.e. run a query that writes out a new query as a string, then that string gets executed)

Is this query designed to be used with Crystal? In an earlier related question it was suggested you use Crystal's crosstab capabilities instead of SQL; you might be well advised to do that instead of attempting dynamic sql.

What is the date format for the date_create field?

Star79Author Commented:
date_create field format is smalldatetime like 1989-07-07 00:00:00

Vitor MontalvãoConnect With a Mentor MSSQL Senior EngineerCommented:
If it's smalldatetime you shouldn't compare it with a varchar.
Anyway, I think you can simplify your query with a group by year and month. Try this select:
SELECT
	nsn, speedex_id, year(date_create), month(date_create), sum(qty_required) as total_qty
FROM d_item1
WHERE date_create >= DATEADD(MONTH, DATEDIFF(MONTH, 0, GETDATE()) -24, 0)
    and date_create <= DATEADD(s,-1,DATEADD(mm, DATEDIFF(m,0,GETDATE()),0))
	and status between '01' and '79'
	and program in ('770','772','773','774','775','776','778','779')
GROUP BY nsn, speedex_id, year(date_create), month(date_create)

Thanks for all the queries but Iam looking to extract data in a pivot form.Please let me know.

I understand you want a pivot but perhaps you could answer my questions?

>>"is there a way to tell the Month and year for month1, month2..instead say March 2014,April 2014" ?

Q1 Do you mean is there a way to have column headings of "March 2014" instead of "Month1"?

Q2 Is this query designed to be used with Crystal?

If you do want "dynamic column headings" this is MUCH MORE DIFFICULT and might not be suitable for Crystal.

A Crystal crosstab might be your best option. (i.e. get Crystal to do the "pivot" for you, don't do a pivot in sql)

Iam using Pentaho for the reporting.it has some issues with dynamic pivot.So I had to use sub-reports to get the column headers and the details section
