in thread array references in DBI

It works as expected on my computer (Activestate Perl 5.8.7)

# perl v5.8.7 [MSWin32-x86-multi-thread]
> my @array= qw/een twee drie vier/;
> my $arrayref = \@array;
> print $arrayref;
ARRAY(0x2089584)
> pop @$arrayref;
vier
> my $temp = pop @$arrayref;
> print $temp;
drie

Sorry, I should have been much more specific, as it's probably also my confusion as to how DBI works. If I do something like: `my $ratest = $dbh->selectrow_arrayref($sql); my $testorder = pop @$ratest;` [download] I get an error: Modification of a read-only value attempted	[reply] [d/l]

Did selectrow_arrayref() actually return an array ref? If the $sql failed, $ratest will be 0 (a literal).	[reply]

Yes. I can access the data via, eg. `$ratest->[0]` [download]	[reply] [d/l]
