Definitely. I once made the same mistake as the OP and it still worked, but one shouldn't count on that. There's no guarantee that it'll work with different database drivers, different versions of the driver being used, or even from call to call.

Aside from that, the OP should consider using selectrow_array since only the first row is fetched. 

my $sth = $db->prepare('SELECT * FROM milton1');
$sth->execute();
my ($additionaltext) = $sth->fetchrow_array;
$sth->finish;

becomes 

my ($additionaltext) = $db->selectrow_array('SELECT * FROM milton1');

I'm also annoyed by the inconsistency between $db and $sth. Use "h" for both or for neither. Actually, use "h" for both to be consistent with all the documentation out there.
