DATEFROMPARTS() returns a date value for the specified year, month, and day.

Let us understand this with an example.

The SQL code for returning day, month and year parameters as a date would probably look something like this

DECLARE @Day INT = 07, @Month int = 03,@Year INT = 2014
SELECT CONVERT(datetime,CONVERT(varchar(10),@Year) + '-' +
CONVERT(varchar(10),@Month) + '-' +
CONVERT(varchar(10),@Day),103) AS TheDate

Now lets implement DATEFROMPARTS

Here is the code for the same

DECLARE @Day INT = 07,
@Month int = 03,
@Year INT = 2014
SELECT DATEFROMPARTS (@Year, @Month, @Day) AS TheDate
