array references in DBI

BrianC has asked for the wisdom of the Perl Monks concerning the following question:

Hi,

I'm trying to figure out why

while (my @an = $sth->fetchrow_array) {
     push (@OrderedQuestions, \@an);
}
[download]

works but

while (my $ran = $sth->fetchrow_arrayref) {
    push (@OrderedQuestions, $ran);
}
[download]

doesn't.

Could anyone enlighten me?

Thanks in advance,
Brian
