How do I strip the date off of a datetime string in SQL SSIS?

Question

I\'m working on a data warehouse project and would like to know how to (preferably in a Derived Column component in a Data flow) strip the date piece off of a SQL datetime r

Answer 1

I personally use a series of functions for this. E.g.:

ALTER FUNCTION [dbo].[TIMEVALUE]
(
 @Datetime datetime
)
RETURNS datetime
AS
BEGIN
    RETURN (@Datetime - CAST(ROUND(CAST(@Datetime AS float), 0, 1) AS datetime))
END

I'd love to claim all the credit but it should really go to this guy.
