Basic Kohana ORM find records

I want to fetch some rows from my databases using the default ORM that Kohana 3 has, but I'm not getting what I want :-)

In my Controller:

$comptes = ORM::factory('compte');
#$comptes->where('empresa_id', '=', 2)->find_all();
$comptes->find_all();

This Query returns 169411 rows in my SQL, but here returns nothing. Of course I can limit using where, limit, or whatever, but I'm experimenting the basics with Kohana.

This returns 1
$result = count($comptes);



In my model view:
<?php var_dump($comptes)?>

produces this:
object(Model_Compte)#16 (34) { ["_has_one":protected]=> array(0) { } ["_belongs_to":protected]=> array(0) { } ["_has_many":protected]=> array(0) { } ["_load_with":protected]=> array(0) { } ["_validation":protected]=> NULL ["_object":protected]=> array(14) { ["id"]=> NULL ["empresa_id"]=> NULL ["codi_compte"]=> NULL ["compte"]=> NULL ["tipus"]=> NULL ["saldo_deure"]=> NULL ["saldo_haver"]=> NULL ["saldo"]=> NULL ["nivell"]=> NULL ["ultim_moviment"]=> NULL ["client_id"]=> NULL...

So this is the model, but how I can get the fetched data?

Also in my view:

foreach ($comptes as $row)
{
 echo "<p>$row->codi_compte</p>";
}
?>

But I don't get nothing ...

thanks!

EDIT

This doesn't work:

$comptes = ORM::factory('compte');
$comptes->find_all();

But this works $comptes = ORM::factory('compte')->find_all();

Why?

And this doesn't work:

$comptes = ORM::factory('compte');
$comptes->where('empresa_id', '=', 2)->find_all();

But again, this works:

$comptes = ORM::factory('compte')->where('empresa_id', '=', 2)->find_all();

This multi-lines examples are from Kohana Web

The correct syntax to get all the rows would be:

$comptes = ORM::factory('compte')->find_all();

Then to check if something has been loaded use $comptes->loaded() (not count($comptes)).

Edit:

To get rows using a where statement, you would write:

$rows = ORM::factory('compte')->where('empresa_id', '=', 2)->find_all();
