That is an extremely broad question? have you tried anything as of yet? do you have a specific question about a particular element? For example do you know how to do everything but calculate the Qtr number?

I have to insert data into the table at the end of each quarter for the past 10 years.

For now i am able to insert data for the past 10 years.but i need it for quarterly.

-- Set @EOM to end-of-last-quarter date

DECLARE @EOM datetime

SET @EOM = CAST(YEAR(GETDATE()) as varchar(4)) + '-'

+ CAST((MONTH(GETDATE())-1) / 3 * 3 + 1 AS varchar)

+ '-01'

SET @EOM = DATEADD(day,-1,@EOM)

--SET @EOM = '03-31-2010' -- For Testing Purpose

--PRINT @EOM

--Table to Include Last 10 years Worth of Sales Amt data at the End of Each Year

Declare @StartDate datetime

Declare @EndDate datetime

SET @StartDate = CONVERT(DATETIME, CAST(YEAR(@EOM)-10 as varchar(4)) + '-01-01',120)

SET @EndDate = DATEADD(year,1,@StartDate-1)

--PRINT @Startdate

--PRINT @EndDate

--Loop to retrieve past 10 years worth of Data at the end of each year

WHILE @EndDate < @EOM

BEGIN

SET @StartDate = DATEADD(Year,1,@StartDate)

SET @EndDate = DATEADD(Year,1,@EndDate)

IF @EndDate > @EOM

SET @EndDate=@EOM

--Insert into Table ---- @EndDate

-- PRINT CONVERT(varchar(11),@StartDate,113) + ' - ' + CONVERT(varchar(11),@EndDate,113)

End

I am still not sure where your question is but I am assuming it is in the date portion of your query.

the following will return the quarter date. You can use this concept to pull dates that fall in that quarter.

select datepart(qq,getdate())

I also see you use a loop to pull the sales.

Take a look at this article from Jeff Moden I is a very usual piece of information and describes the same type of this you are talking about.

This will show you how to convert a range of dates into year/quarters. I'm also adding in the first and last date/time for each quarter. You should be able to use this to go forth and adapt to your requirements.

declare @StartDate datetime

set @StartDate = DateAdd(month, -1, DateAdd(year, DATEDIFF(year, 0, GetDate()), 0))

-- See Jeff Moden's article

-- The "Numbers" or "Tally" Table: What it is and how it replaces a loop.

-- at http://www.sqlservercentral.com/articles/T-SQL/62867/.

-- NOTE! A permanent tally table will always be MUCH faster

-- than this inline one. See the above article to create your own!

;WITH

Tens (N) AS (SELECT 0 UNION ALL SELECT 0 UNION ALL SELECT 0 UNION ALL

SELECT 0 UNION ALL SELECT 0 UNION ALL SELECT 0 UNION ALL

SELECT 0 UNION ALL SELECT 0 UNION ALL SELECT 0 UNION ALL SELECT 0),

Tally (N) AS (SELECT ROW_NUMBER() OVER (ORDER BY (SELECT 0)) FROM Tens t1 CROSS JOIN Tens t2),

Dates AS (SELECT MyDate = DateAdd(month, N, @StartDate) FROM Tally ),

Quarters AS (SELECT MyDate, MyYear = YEAR(MyDate), Qtr = DatePart(quarter, MyDate)

FROM Dates)

SELECT MyYear, Qtr,

QtrStartDate = MIN(MyDate),

QtrEndDate = MAX(DateAdd(ms, -3, DateAdd(month, 1, MyDate)))

FROM Quarters

GROUP BY MyYear, Qtr

ORDER BY MyYear, Qtr
