From this snippet and the first one I can understand that data is an array that references hashes. This last snippet shows that data may be defined with the result of the call to exec_select. Still, that shows no guarantee that the hashes in data have the keys $_->{TEST34} and $_->{TEST33}. You may be assuming that they are present, but they are not.
