Tip of the Day: A DateOnly function in SQL Server

It occurs to me that I’ve probably written several versions of this function in various installations on SQL Sever over the last 10+ years (10 years 2 months, 26 days – to be exact) since I started using SQL Server. I should really put it somewhere that I can refer to it easily and not have to re-write it again. (So why not put it in my blog?)

It’s a simple little thing that takes a DATETIME and returns the same but without the time elements, basically, it returns the date only.

CREATE FUNCTION [dbo].[DateOnly]
  @DateTime DATETIME
          DATEADD(HOUR, -DATEPART(HOUR, @DateTime), @DateTime))));

    You can also use CONVERT(DATE, )
