Three Ways To Get The Time Portion Of A Datetime Value

This popped up in a newsgroup today so I decided to do a little post about it. How do you get the time information only from a datetime value
These are at least 3 ways to do this

1) use the 3 different datepart functions and concatenate them
2) convert and grab the 8 right most characters
3) convert to varchar and use style 108

So here we go

--1 use the 3 different datepart functions and concatenate them
SELECT CONVERT(VARCHAR(2),DATEPART(HH,GETDATE())) + ':' +
CONVERT(VARCHAR(2),DATEPART(MI,GETDATE())) + ':' +
CONVERT(VARCHAR(2),DATEPART(S,GETDATE()))

--2 convert and grab the 8 right most characters
SELECT RIGHT(CONVERT(VARCHAR(22),GETDATE(),120),8)


--3 convert to varchar and use style 108
SELECT CONVERT(VARCHAR(12),GETDATE(),108)
