in reply to How to tweak an AoH?

How are keys unecessary to a hash??? Maybe you want something like: 
...

$sth->execute(...) or die(...);

my %field_idx = do {
   my $i = 0;
   map { $_ => $i++ } @{$sth->{NAMES}}
};

my $row;
while ($row = $sth->fetch()) {
   print($row->[$field_idx{'userid'  }], $/);
   print($row->[$field_idx{'password'}], $/);
}

...

    Of course they are necessary to a normal hash - but for an AoH it isn't necessary to have complete hashes cause the keys for each row are always the same.
