Update values in a table
In the table Resapost I want to update value in the field AvrDat.The value should come from the field Avrakning in table Fakturerad, where Fakturerad.Taxinr = Resapost.Taxinr And Fakturerad.Kvitto = Resapost.Kvitto And Fakturerad.StartDat = Resapost.StartDat.
I made an update query and set the above criterias, but it does'nt work. How should it be done?
