Perl newbie question

Can someone tell me what this is doing? I know it is reading records from a table and puts them in a hash. How do I print out, let's say, the first 5 columns of data (assuming columns are named col1, col2, ...)?

    $sth = $dbh->prepare("select *
                          from stsc.loc
                          where p_loclevel = 4 and rownum < 11");
    while (my $hash_ref = $sth->fetchrow_hashref('NAME_lc'))
        $dlrinfo{$hash_ref->{loc}} = \%$hash_ref;
