Instead of this:
push (@loopData, $data);
You may want to do this instead:
push (@loopDate, \%{$data});
Which creates a copy of the hash and passes its rerference instead.
>From the DBI perldoc:
Currently, a new hash reference is returned for each
row. This will change in the future to return the
same hash ref each time, so don't rely on the current
behaviour.
Which if you use the code at the top, and then the above takes effect,
every row would have a reference to the last row's data.
