Remove time part from date in SQL Server

If we want to remove time part from the date without converting the date to varchar.

Example:

SELECT GETDATE() gives the Current Date.
i.e, 2012-01-26 23:38:21.983

Now f I want only the date part i.e, 2012-01-26 00:00:00.000.
But I don't want to convert it to varchar.

Below is the code.

SELECT DATEADD(DAY,DATEDIFF(DAY,0,GETDATE()),0)

Output:
2012-01-26 00:00:00.000
