If you're looking up by PK why not just use find() ?

if (my $client = $c->model('AppModelDB::Clients')->find({ id => $id })) {
  ... do stuff ...
} else {
  $self->handle_error;
}

Notes:

You're writing in an OO system, use methods not functions.

You're writing perl, use names_like_this not namesLikeJava.

If you actually -do- want an rs then if (defined $rs->first) or if ($rs->count)
are sufficient.
