Question

I know it’s a simple question, but I’m stuck. I tried DateDiff day and hour seperately but I want my date can detect my time if its over 24 hours.

For example:

Date1: 20/12/2011
Time1: 9:00

Date2: 21/12/2011
Time2 : 13:00

Days Taken: 1
Time Taken: 28

I want to calculate the days and hours, so 1 day and 4 hours is my desired result.

Can anyone please help me how to do with this? Appreciate.

Perhaps with the help of MODULO:

SELECT (
  DATEDIFF(dd,
    CONVERT(datetime,'20/12/2011 09:00:00',104),
    CONVERT(datetime,'21/12/2011 13:00:00',104))
 ) AS [days taken],
(
  DATEDIFF(hh,
    CONVERT(datetime,'20/12/2011 09:00:00',104),
    CONVERT(datetime,'21/12/2011 13:00:00',104))
   % 24
 ) AS [hours taken]

Result:

DAYS TAKEN      HOURS TAKEN
    1                4
