I am building an account-program, for that:
I want to update a field in an access table.
The field should add the value in tableR.bedrag
with the sum in tabelb.bedrag in a certain periode
A bit like this:
Update TableB set Bedrag = TableR.Bedrag + SUm(tableB.bedrag) where datum between fromdate and todate.
where TabelR.bedrag is the value from a previous periode, written in tabelR
Thanks in advance
