where 8 represents hour part and 36 repres

Answer 1

Try this query

select
    *,
    Days          = datediff(dd,0,DateDif),
    Hours         = datepart(hour,DateDif),
    Minutes       = datepart(minute,DateDif),
    Seconds       = datepart(second,DateDif),
    MS            = datepart(ms,DateDif)
from
    (select
         DateDif = EndDate-StartDate,
         aa.*
     from
         (  -- Test Data
          Select
              StartDate = convert(datetime,'20090213 02:44:37.923'),
              EndDate   = convert(datetime,'20090715 13:24:45.837')) aa
    ) a

Output

DateDif                  StartDate                EndDate                 Days Hours Minutes Seconds MS
-----------------------  -----------------------  ----------------------- ---- ----- ------- ------- ---
1900-06-02 10:40:07.913  2009-02-13 02:44:37.923  2009-07-15 13:24:45.837 152  10    40      7       913

Answer 2

Very simply:

CONVERT(TIME,Date2 - Date1)

For example:

Declare @Date2 DATETIME = '2016-01-01 10:01:10.022'
Declare @Date1 DATETIME = '2016-01-01 10:00:00.000'
Select CONVERT(TIME,@Date2 - @Date1) as ElapsedTime

Yelds:

ElapsedTime
----------------
00:01:10.0233333

Answer 3

Please put your related value and try this :

declare @x int, @y varchar(200),
        @dt1 smalldatetime = '2014-01-21 10:00:00', 
        @dt2 smalldatetime = getdate()

set @x = datediff (HOUR, @dt1, @dt2)
set @y =  @x * 60 -  DATEDIFF(minute,@dt1, @dt2)
set @y = cast(@x as varchar(200)) + ':' + @y
Select @y

Answer 4

In case someone is still searching for a query to display the difference in hr min and sec format: (This will display the difference in this format: 2 hr 20 min 22 secs)

SELECT
CAST(DATEDIFF(minute, StartDateTime, EndDateTime)/ 60 as nvarchar(20)) + ' hrs ' + CAST(DATEDIFF(second, StartDateTime, EndDateTime)/60 as nvarchar(20)) + ' mins' +          CAST(DATEDIFF(second, StartDateTime, EndDateTime)% 60 as nvarchar(20))  + ' secs'

OR can be in the format as in the question:

CAST(DATEDIFF(minute, StartDateTime, EndDateTime)/ 60 as nvarchar(20)) + ':' + CAST(DATEDIFF(second, StartDateTime, EndDateTime)/60 as nvarchar(20))

Answer 5

this would hep you

 DECLARE @DATE1 datetime = '2014-01-22 9:07:58.923'
 DECLARE @DATE2 datetime = '2014-01-22 10:20:58.923'
 SELECT DATEDIFF(HOUR, @DATE1,@DATE2) ,
        DATEDIFF(MINUTE, @DATE1,@DATE2) - (DATEDIFF(HOUR,@DATE1,@DATE2)*60)

 SELECT CAST(DATEDIFF(HOUR, @DATE1,@DATE2) AS nvarchar(200)) +
        ':'+ CAST(DATEDIFF(MINUTE, @DATE1,@DATE2)  -
                 (DATEDIFF(HOUR,@DATE1,@DATE2)*60) AS nvarchar(200))
As TotalHours 

Answer 6

No need to jump through hoops. Subtracting Start from End essentially gives you the timespan (combining Vignesh Kumar's and Carl Nitzsche's answers) :

SELECT *,
    --as a time object
    TotalHours = CONVERT(time, EndDate - StartDate),
    --as a formatted string
    TotalHoursText = CONVERT(varchar(20), EndDate - StartDate, 114)
FROM (
    --some test values (across days, but OP only cares about the time, not date)
    SELECT
        StartDate = CONVERT(datetime,'20090213 02:44:37.923'),
        EndDate   = CONVERT(datetime,'20090715 13:24:45.837')
) t

Ouput

StartDate               EndDate                 TotalHours       TotalHoursText
----------------------- ----------------------- ---------------- --------------------
2009-02-13 02:44:37.923 2009-07-15 13:24:45.837 10:40:07.9130000 10:40:07:913
