MS Access: Summing time greater than 24 hours in q

Question

I have a table trans_hist in MS Access program where time is stored in short Date format "HH:MM" ex:

Now I have created a query which tells total time for each user (Just simply summing the time) but if the total time exceeds 24 hours then it resets and starts over again from 00:15(all time are stored in 15 minutes intervals)

Problem: For Customer(UID) 1 the total time should have been 32:30 however it shows 8:30

Current Result:

UID Time_Elapsed
1   5:00
1   8:30
1   9:00
1   6:00
2   2:15
2   2:00
3   1:15
5   4:00
1   4:00

Result:

Answer 1

Try this.

SELECT UID, switch (
t>1 , '00:15' 
,true,format(t,'hh:mm')
) as Time_Elapsed from
(
SELECT UID, sum(Time_Elapsed) as t
From Table1
Group By UID
)

Answer 2

I hope, this SQL query helps:

SELECT T.UID,
       CSTR(total_hours 
                + INT(total_min / 60)) 
                + ":" 
                + CSTR(total_min Mod 60) as result
FROM
    (SELECT UID,
            SUM(HOUR(TH.time_elapsed)) AS total_hours,
            SUM(MINUTE(TH.time_elapsed)) AS total_min
    FROM trans_hist AS TH
    GROUP BY UID) AS T

Answer 3

Use a function like this:

Public Function FormatHourMinute( _
  ByVal datTime As Date, _
  Optional ByVal strSeparator As String = ":") _
  As String

' Returns count of days, hours and minutes of datTime
' converted to hours and minutes as a formatted string
' with an optional choice of time separator.
'
' Example:
'   datTime: #10:03# + #20:01#
'   returns: 30:04
'
' 2005-02-05. Cactus Data ApS, CPH.

  Dim strHour       As String
  Dim strMinute     As String
  Dim strHourMinute As String

  strHour = CStr(Fix(datTime) * 24 + Hour(datTime))
  ' Add leading zero to minute count when needed.
  strMinute = Right("0" & CStr(Minute(datTime)), 2)
  strHourMinute = strHour & strSeparator & strMinute

  FormatHourMinute = strHourMinute

End Function

and a simple query:

Select 
    UID,
    FormatHourMinute(Sum([Time_Elapsed])) As TotalTime
From
    trans_hist 
Group By
    UID
