Last Modified: 2012-05-06
I would like to add a field to my existing query that would perform a sum calculation off of a field in the table that is shown in the query.  THis field is a cumulative amount that is not in any table.  For example; I know the Machine Num and would like to calculate the cumulated Operating hours.  Table has MachNum and OpHrs.  I am passing the MachNum from another form so I know that coming in.

something like this may help you...

SELECT MachineNum, SUM(OpHrs)
FROM yourTable
WHERE MachineNum = @MachineNum
GROUP BY MachineNum

try this:

SELECT Table1.FIELD1, Sum(Table1.FIELD2) AS OpHrs
FROM Table1
WHERE (((Table1.FIELD1)=[Forms].[YourFormName].[txtMachNum]))

Where FIELD1 is MachNum , FIELD2 = OpHrs

I'm using  txtMachNum as the Name of the control on your form passing the MachNum

It looks like it is working.  I still have more to do to fully test but thanks for your help.

How will this work in an Access database:



Also, the Accepted solution does not take into account

"I am passing the MachNum from another form so I know that coming in."
