Method of subtracting two fields
Add calculated field and add formula:
( field1 - field2 )
Or if You need to permanently add it You will need formula
procedure frmUlazS_Button1_OnClick (Sender: TObject; var Cancel: boolean);
Begin
SqlExecute('Update TABLE1 Set amount = amount - ' + frmUlazS.Edit2.sqlValue + ' Where id = ' + frmUlazS.ComboBox1.sqlValue);
end;
