I want to have startdate & enddate for 2009

Startdate should be Jan 31st 2009
EndDate should be March 31st 2009(Since Last Accounting Month is March)

Since, i need to use these dates in While Loop to run Temp Table.
Since for Every month end I need to run Procedure. So, i need to insert the code for StartDate & EndDate

I already wrote Below Code, but it doesnt work for March...The code is taking March 28th instead of March 31st, Since, Feb Month runs for 28th.

Declare @StartDate datetime
Declare @EndDate datetime

Set @EndDate = CONVERT(varchar,DATEADD(d,-DAY(GetDate()),GetDate()),101)
Set @StartDate = '1/31/'+ CAST(YEAR(@EndDate)as Char(4))

--Print @StartDate
--Print @EndDate

--Create Table

While @StartDate <= @EndDate
Begin

--Inserting Data into table

set @StartDate = dateadd(m, 1, @StartDate)
End

Try like this:



Set @StartDate = DATEADD(month, 0, DATEDIFF(day, 0, GETDATE()) - DATEPART(dy, GETDATE()) + 1)Set @EndDate = DATEADD(month, 0, DATEDIFF(day, 0, GETDATE()) - DAY(GETDATE()) + 1)
 
WHILE @StartDate < @EndDate

Try this -
Declare @StartDate datetime
Declare @EndDate datetime
Declare	@WorkDate datetime
 
Set @EndDate = CONVERT(varchar,DATEADD(d,-DAY(GetDate()),GetDate()),101)
Set @WorkDate =  '01/01/'+ CAST(YEAR(@EndDate)as Char(4))
--Print @StartDate
--Print @EndDate
 
--Create Table
 
While @WorkDate < @EndDate
Begin
	Set @StartDate = DATEADD(d, -1, DATEADD(m, 1, @WorkDate))
 
--Inserting Data into table
 
	set @WorkDate = DATEADD(m, 1, @WorkDate)
End

Sorry just caught the January 31st start.  PRevious code gets January 1st.  It would help to know how you were using the date later to make sure my suggestion will work correctly.  I do this sort of analysis with dynamic dates where I am doing _date >= @start_date and _date < @end_date so it works using dates at midnight.

I don't think that the dateadd(m...) will work because adding a month to January 31 gives you Feb-28, but 1 month later is March 28.

Try this, which returns the start as day 1, and end as day 1 of next month.  If you depend upon enddate being the last day of the month, instead of the first day of next month then use the second script.

The difference would be:

SomeField between @Start and @End

vs

SomeField >= @start
and SomeField < @End
Declare 
      @StartDate    datetime
     ,@EndDate      datetime
 
set @startdate = ltrim(str((datepart(yy,getdate())*10000)+101))
set @enddate = dateadd(m,1,@startdate)
while @enddate < getdate()
begin
     select @startdate,@enddate
 
set @startdate = dateadd(m, 1,@startdate)
set @enddate = dateadd(m,1,@startdate)
end
 
 
go
 
Declare 
      @StartDate    datetime
     ,@EndDate      datetime
 
set @startdate = ltrim(str((datepart(yy,getdate())*10000)+101))
set @enddate = dateadd(m,1,@startdate)-1
while @enddate < getdate()
begin
     select @startdate,@enddate
 
set @startdate = dateadd(m, 1,@startdate)
set @enddate = dateadd(m,1,@startdate)-1
end
