Truncating DATETIME Values to Dates without Time in SQL Server

Q

How To Truncate DATETIME Values to Dates without Time in SQL Server Transact-SQL?

✍: FYIcenter.com

A

Assuming that you have some date and time, DATETIME, values, and you want to work with dates only. You want to truncate them to dates without time, or with time of 00:00:00.000.

Again, SQL Server offers no simple solution, you need to write the formula yourself. The tutorial exercise below shows you how to do this with CONVERT() and FLOOR() functions:

-- truncating to dates
DECLARE @local_time DATETIME;
SET @local_time = 'May 19 2007 10:06PM';
SELECT 'Server local date and time: ';
SELECT @local_time;
SELECT 'Server local date without time: ';
SELECT CONVERT(DATETIME,
   FLOOR(CONVERT(NUMERIC(18,9),@local_time)));
GO
Server local date and time: 
2007-05-19 22:06:00.000
Server local date without time: 
2007-05-19 00:00:00.000
