The query is selecting ids, so I assume you mean `1,2,3` as the expectation. Clearly Firebird cannot support what the query is attempting to do - so the best option is to skip this test for Firebird. However, the order-by is really not serving any purpose to the test aside from making the assertions easier; so another option would be to remove the order-by and assert the results via iterating them.
