I have a DBI query... 
$get = $dbh->prepare("SELECT * FROM clients ORDER BY lastname");
$get->execute;

[download]
returning a hash with... 
$clients = $get->fetchall_hashref('id');

[download]
So obviously, the value for each key in the hash is the corresponding row from the database. I get an array of the keys (each rows 'id' field)... 
@list = keys(%{$clients});

[download]
but I need to sort that array by fields in the returned data, not the @list elements themselves. For instance, $clients{'1'}->{'lastname'}. However, by pulling the data with fetchall_hashref, the sorted results are lossed. Any ideas?
