Take the time from the datetime and convert it into seconds?

Question

I am running SQL Server 2005. Technically I know how to take the time from a tsql datetime.

CONVERT(VARCHAR(8),GETDATE(),108) AS HourMinuteSecond

Answer 1

The functions you want is DatePart

Declare @d DateTime
Select @d = GetDate()
Select (DatePart(HOUR, @d) * 3600) + (DatePart(MINUTE, @d) * 60) + DatePart(SECOND, @d)
