declare @dte datetime
Select @dte = GETDATE()
@dte = 2016-10-31 11:42:51.920
Is it possible to convert Time (11:42:51.920) into an INT so that it looks like 114257 ?

Yes., There's a few different ways, for example:

SELECT GETDATE() AS CurrentDateTime,

(DATEPART(HOUR, GETDATE()) * 10000) + (DATEPART(MINUTE, GETDATE()) * 100) + DATEPART(SECOND, GETDATE()) AS CurrentTimeInt

/* date included */

-- A sensible way

SELECT FORMAT(GETDATE(), 'ddMMyyyyhhmm', 'en-GB')

-- The Rube Goldberg way

SELECT LEFT(CAST(REPLACE(CONVERT(VARCHAR, GETDATE(), 103), '/', '') + REPLACE(CONVERT(VARCHAR, GETDATE(), 108), ':', '') AS BIGINT), 12)

-- The SQL# way. Why not, right?

SELECT SQL#.Date_Format(GETDATE(),'ddMMyyyyhhmm','en-GB')

/* just time */

SELECT LEFT(CAST(REPLACE(CONVERT(VARCHAR, GETDATE(), 108), ':', '') AS INT), 6)

SELECT FORMAT(GETDATE(), 'hhmmss', 'en-GB')

SELECT SQL#.Date_Format(GETDATE(),'hhmmss','en-GB')

Although format is easy, if you're applying this to a dataset, I heavily recommend against it. You'll find it to be incredibly slow.

Now that you have a couple of ways to do this, I have to ask WHY do you want to do this? Just like the mistake that MS made for job history in MSDB, times as INTs are a royal pain to do just about anything with. WHAT are you good folks looking to do with times converted to INTs?

RBAR is pronounced "ree-bar" and is a "Modenism" for Row-By-Agonizing-Row.
First step towards the paradigm shift of writing Set Based code:
________Stop thinking about what you want to do to a ROW... think, instead, of what you want to do to a COLUMN.

Change is inevitable... Change for the better is not.
