Question

I am developing a financial application using SQLServer 2008 as database and I want to generate fiscal periods of any year for example

Input : June 2010

Results desired 12 periods from the starting date of June 2010 – May -2011

Period…………….Start…………………………….………..End
1……………………1-06-2010……………………………30-06-2010
2……….1-07-2010………..31-07-2010

And so on untill May 2010 …Actually need to get 12 rows (12 months) starting from any month and output will be the starting date of the month and end would be the last day of the month like for example in my scenario June 2010 – May 2011 ..what will be the query.

Thanks in Advance

Here’s a method using a common table expression to create a list of periods. I’m borrowing @Fosco’s DATEADD approach (thx @Fosco).

DECLARE @StartDate DATETIME = '06/1/2010';

WITH periods AS
    (SELECT 1 AS period
    UNION SELECT 2
    UNION SELECT 3
    UNION SELECT 4
    UNION SELECT 5
    UNION SELECT 6
    UNION SELECT 7
    UNION SELECT 8
    UNION SELECT 9
    UNION SELECT 10
    UNION SELECT 11
    UNION SELECT 12
    )

SELECT period,
    DATEADD(month,period-1,@StartDate) as startDate,
    DATEADD(day,-1,DATEADD(month,period,@StartDate)) as endDate
FROM periods

There are a number of ways to create your list of periods. See this for examples.
