Ah - learned something today - thank you.

I avoid "fetchall_*", because I mostly process a row-at-a-time , and use the clearer syntax of fetchrow_hashref.

The OP's questions were based on managing arrays, and I did not want to bring hashes and confuse that discussion.

Thanks, space_monk.

@All: Thnx a lot for your helpful answers.

With some additional reading and fiddling around with the syntax I have figured this out now.

my @allrows =();

while ($row =  $sth->fetchrow_arrayref() ) {
push @allrows,[@$row];
 };

my $titlesfound = @allrows; # Contains the number of results

#Show that it works: 
$loopcount = 0;
foreach (@allrows) {
my $title1 = ($allrows[$loopcount][1]); print "$title1\n";
$loopcount++;
 };

If you do not need the @allrows array, it is wasteful to store data into it. Try this instead:

my $loopcount = 0;
while (my $row =  $sth->fetchrow_arrayref() ) {
    my $title1 = $row->[1];
        print "$title1\n";
    $loopcount++;
};

my $titlesfound = $loopcount;
