How to create a Date in SQL Server given the Day, Month and Year as Integers

Question

FOR Example if I have:

DECLARE @Day int = 25
DECLARE @Month int  = 10 
DECLARE @Year int = 2016

I want to return

2016-10-2         


        

Answer 1

So, you can try this solution:

DECLARE @DAY INT = 25
DECLARE @MONTH INT  = 10 
DECLARE @YEAR INT = 2016
DECLARE @DATE AS DATETIME

SET @DATE = CAST(RTRIM(@YEAR * 10000 + @MONTH * 100 + @DAY) AS DATETIME) 

SELECT REPLACE(CONVERT(VARCHAR(10), @DATE, 102), '.', '-') AS EXPECTDATE

Or you can try this a few lines of code:

DECLARE @DAY INT = 25
DECLARE @MONTH INT  = 10 
DECLARE @YEAR INT = 2016

SELECT CAST(RTRIM(@YEAR * 10000 +'-' +  @MONTH * 100+ '-' + @DAY) AS DATE) AS EXPECTDATE
