Hi,

I'd suggest that instead of taking the datediff by hours that you do it in minutes else get only whole hours. And the amount of hours isn't whole hours as the code snippet shows.

Of course if you want hours you'll have to divide the minutes by 60, but you know that.

Cheers
David

select
datediff( hour, @StartDate, @EndDate ) as hours
, datediff( minute, @StartDate, @EndDate ) as mins
