No, there are no such properties. But you can use TDataSet.BeforeInsert,
etc. events to call Abort procedure.

You can add this code in your copy of SDAC sources, but it will be incompatible with the next builds of SDAC. I think it is better to use something like this in your application (not in SDAC sources):

Code: Select all

  procedure TForm1.MSQuery1BeforeInsert(DataSet: TDataSet);
  begin
  if not CanInsert then
    Abort;
  end;
