Datediff - Years / Months / Days / Hours / Minutes

I've a slight problem with the datediff() SQL function.

Code:

---

Select
DATEDIFF(day, Startdatum, getdate()) AS aantal_dagen,
DATEDIFF(Hour, Startdatum, getdate()) AS aantal_uren,
DATEDIFF(Minute, Startdatum, getdate()) AS aantal_minuten,
DATEDIFF(Month, Startdatum, getdate()) AS aantal_maanden,
(DATEDIFF(Minute, Startdatum, getdate()) % 60) as minuutje,
((DATEDIFF(Minute, Startdatum, getdate()) - (DATEDIFF(Minute, Startdatum, getdate()) % 60)) / 60) as uurtje
FROM Bla

---

I'd like to get the Years / Months / Days / Hours / Minutes from the calculation...
When I do the DATEDIFF(Minute, Startdatum, getdate()) I only want the real minutes....not like 500...but 8 hours and 20 minutes...

Select
((DATEDIFF(day, Startdatum, getdate()) / 60 + 'Hrs' + (DATEDIFF(day, Startdatum, getdate()) %60 + 'min') AS aantal_quackquack


Try that. "+" is supposed to be the concatenation operator, so it could also be "&".

You could use this function:
If you want hours and minutes displayed just pass the
string "hn" as the interval and it will return a string formated
as x hours x minutes.

    ' Description:  This function calculates the number of years,
    '          months, days, hours, minutes and seconds between
    '          two dates, as elapsed time.
    '
    ' Inputs:    Interval:  Intervals to be displayed (a string)
    '          Date1:      The lower date (see below)
    '          Date2:      The higher date (see below)
    '          ShowZero:  Boolean to select showing zero elements
    '
    ' Outputs:  On error: Null
    '          On no error: Variant containing the number of years,
    '              months, days, hours, minutes & seconds between
    '              the two dates, depending on the display interval
    '              selected.
    '          If Date1 is greater than Date2, the result will
    '              be a negative value.
    '          The function compensates for the lack of any intervals
    '              not listed. For example, if Interval lists "m", but
    '              not "y", the function adds the value of the year
    '              component to the month component.
    '          If ShowZero is True, and an output element is zero, it
    '              is displayed. However, if ShowZero is False or
    '              omitted, no zero-value elements are displayed.
    '              For example, with ShowZero = False, Interval="ym",
    '              elements = 0 & 1 respectively, the output string
    '              will be "1 month" - not "0 years 1 month".
