Setting the Access Mode

Go Up to Setting Database Properties Using InterBase Services

Set the SetReadOnly method of the IBConfigService component to True to set the database access mode to read-only.

procedure TDBConfigForm.CheckBox1Click(Sender: TObject);
begin
  with IBConfigService1 do
  begin
    SetReadOnly(True);
  end;
end;

Note: Once you set the database to read-only, you will be unable to change any of the other database options until you set SetReadOnly method to False again.

For more information on access mode, refer to “Read-only databases” in the Operations Guide.
