How exactly is fetchrow_hashref more efficient? From the DBI docs:
Because of the extra work "fetchrow_hashref" and Perl
have to perform, it is not as efficient as
"fetchrow_arrayref" or "fetchrow_array".

Also, you should not save the reference in an array, you may get bitten later. Also from the DBI docs:
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.

If you really need to save all the results in an array of hashes, use selectall_arrayref (this changed recently, selectall_hashref use to be the solution to this, but as of DBI 1.20 it now returns a hashref, not an array). If you want to prepare the statement, that's fine, the selectall_* methods will take a sql string or a statement handle as an argument, or you can use one of the new fetchall_* methods.
