This question have been asked many times but i cannot find any easy answers on how to get hours and minutes from a datediff().
From To OUTPUT
08:00 16:30 8,5
10:00 16:30 6,5
08:00 15:00 7
I would like to use datediff() and want the output as my result
回答1:
just take datediff() by minute and then divide by 60
select datediff(minute, '08:00', '16:30') / 60.0

Sorry, I answered C# question first :)
What you're after is this:
SELECT datediff(minute, starttime, endtime) from ...
of course, you can apply this to hours too. For Hours AND minutes, you can use this example:
DECLARE @start datetime
, @end datetime
SELECT @start = '2009-01-01'
, @end = DateAdd(mi, 52, DateAdd(hh, 18, DateAdd(dd, 2, @start)))
SELECT @start
, @end
SELECT DateDiff(dd, @start, @end) As days
, DateDiff(hh, @start, @end) % 24 As hours
, DateDiff(mi, @start, @end) % 60 As mins

I went with
DATEDIFF(second, start_date, end_date) / 3600.0
Thank you all for the answers...!!.
