Thank you John,

I did know about the new date only feature but needed to update this article accordingly. Thanks, it is much easier to read.

From SS2008 onwards you can use the ‘date’ datatype.

SELECT Cast(GetDate() AS date);
– works fine, as does

DECLARE @dateonly date = GetDate();
SELECT @dateonly;

I find the above much easier to read in code.

a diferent approach:

create FUNCTION [dbo].[TimeOnly] ( @DateTime DATETIME )
RETURNS DATETIME
AS BEGIN
RETURN DATEADD(day, -DATEDIFF(day, 0, @datetime), @datetime)
END
GO

CREATE FUNCTION [dbo].[DateOnly] ( @DateTime DATETIME )
RETURNS DATETIME
AS BEGIN
RETURN DATEADD(dd, 0, DATEDIFF(dd, 0, @DateTime))
END
