Hi,

try like below.

SQL

DECLARE @startdt DATETIME, @enddt DATETIME
SELECT @startdt =  '2013-02-03', @enddt =  '2013-12-10'

DECLARE @Sessions TABLE (FromDate DateTime, EndDate DateTime)

WHILE @startdt < @enddt
BEGIN

    if(DATEADD(s,-1,DATEADD(mm, DATEDIFF(m,0,@startdt)+1,0)) > @enddt )
    INSERT INTO @Sessions VALUES (@startdt, @enddt)
    else
    INSERT INTO @Sessions VALUES (@startdt, DATEADD(s,-1,DATEADD(mm, DATEDIFF(m,0,@startdt)+1,0)))
    SET @enddt = DATEADD(s,-1,DATEADD(mm, DATEDIFF(m,0,@startdt)+1,0))
    SET  @startdt = DATEADD(DAY,1,@startdt)
END

SELECT * FROM @Sessions

hope it works.

hi all
finally i used this code

SQL

DECLARE @date1 DATETIME, @date2 DATETIME, @date3 DATETIME, @lastdate DATETIME, @totalMonths INT,@totalDays INT,@counter INT
SET @date1 = '10/22/2011'SET @date2 = '05/25/2012'
SET @totalMonths = DATEDIFF(m, @date1, @date2)
        CREATE TABLE #temp_months
        (start datetime, [end] datetime)
        SET @counter = 0
        SELECT @lastdate= DATEADD( D, -1, DATEADD( mm, DATEDIFF( m, 0, @date1 ) + 1, 0 ) )+1;
        WHILE @counter <@totalMonths
        BEGIN
                SELECT @totalDays=DATEDIFF (d,@date1,@lastdate)
                SELECT @date3=DATEADD(dd,-(DAY(DATEADD(mm,1,@date1))),DATEADD(mm,1,@date1))
                INSERT INTO #temp_months(start,[end]) VALUES (@date1,@date3)
                SET @counter = @counter + 1
                SET @date1=@lastdate
                SET @lastdate = DATEADD(Month, 1, @date1)
         END
       SELECT * FROM #temp_months
drop table #temp_months
