Hi,

In Delphi I can calculate the number of minutes between two dates by using the function:
MinutesBetweenEx(StartDateTime, EndDateTime);

Is there a way to do this within a query?
I'm using a MS Access database.

Regards,
Stef

Assuming MS Access has the function DATEDIFF

SELECT DateDiff( mi, <STARTDATE>, <ENDDATE>) AS MinutesBetween

I guess it should be :
SELECT DateDiff( "n", <STARTDATE>, <ENDDATE>) AS MinutesBetween

instead of

SELECT DateDiff( mi, <STARTDATE>, <ENDDATE>) AS MinutesBetween

And use :

For Hours    : SELECT DateDiff( "h", <STARTDATE>, <ENDDATE>) AS HoursBetween
For Minutes : SELECT DateDiff( "n", <STARTDATE>, <ENDDATE>) AS MinutesBetween
For seconds : SELECT DateDiff( "s", <STARTDATE>, <ENDDATE>) AS SecondsBetween

Little Extention to what you were asking :

SELECT FromDate, ToDate,
       DATEDIFF( "s", FromDate, ToDate) as TotalSeconds,
       INT(TotalSeconds / 3600) as Hours,
       INT( ((TotalSeconds / 3600) - Hours) *60 ) as Minutes,
       INT( ((((TotalSeconds / 3600) - Hours) *60) - Minutes) *60 ) as Seconds

Thank you both very much for the solution.
I never knew that you can use the "as"-value within the statement.
