DECLARE @s datetime, @e datetime
SELECT @s = '10/24/1960', @e = Getdate()
SELECT DATEDIFF(hh,@s,@e)

Man that's a lot of hours

huh?

What is the datatype of your "time" values?
Can you provide an example of what you have and what you want?

You do know that you can convert seconds to hours by deviding by 3600.0, right?

SELECT (ToSecondsColumn - FromSecondsColumn) / 3600.0 DiffInHours
FROM MyTable

Good Lord


DECLARE @s datetime, @e datetime
SELECT @s = '10/24/1960', @e = Getdate()
SELECT DATEDIFF(ss,@s,@e)
