SQL Server 2005 Get First and Last date for any Month in any Year

Question

I have a stored procedure that has to accept a month as int (1-12) and a year as int. Given those two values, I have to determine the date range of that month. So I need a d

Answer 1

Current month last Date:

select dateadd(dd,-day(dateadd(mm,1,getdate())),dateadd(mm,1,getdate()))

Current month 1st Date:

select dateadd(dd,-day(getdate())+1,getdate())

Answer 2

DECLARE @Month  int = 3, @Year  int = 2016
DECLARE @StartDate DATETIME
DECLARE @EndDate DATETIME

-- First date of month
SET @StartDate = DATEADD(MONTH, @Month-1, DATEADD(YEAR, @Year-1900, 0));
-- Last date of month
SET @EndDate = DATEADD(SS, -1, DATEADD(MONTH, @Month, DATEADD(YEAR, @Year-1900, 0)))

This will return first date and last date with time component.

select [FirstDay Of The Month] as Text ,convert(varchar,dateadd(d,-(day(getdate()-1)),getdate()),106) 'Date'
union all
select [LastDay Of The Month], convert(varchar,dateadd(d,-day(getdate()),dateadd(m,1,getdate())),106)
