As before...all of those tools are built with Delphi, which enscapsulates
the output of a SELECT query in a Dataset object. All it's telling you is
that there is no data output from your query and therefore the operation
you are requesting on it (scrolling, locating, etc.) won't work. By its
own rules, the dataset is asking (through the API) "Send me more rows" and
the client is replying "How can I send you more rows when there are none?"

So - test for an empty dataset before you try to make any requests
concerning rows in it.
