    if (! $ BDRes-> GetNext ())

    It is not necessary to check the presence of elements in the sample, because in this case, you get the first element and then, in a loop, start processing starting from the second element.

    If you need to know the presence of elements in the sample, use the SelectedRowsCount method, which returns the number of selected records.
