What is the preferred way to load one record with doctrine?

I am using

```
$em = EntityManager::create($connectionOptions, $config);
$dql = "select r from Rolle r";
$list = $em->createQuery($dql)->getResult();

```

to get a list of records.

I tried using

```
$dql = Doctrine_Query::create()
    ->from('Rolle r') 
    ->where('r.ID = 14');
$rolle = $dql->fetchArray();

```

to get one record. Is this the preferred way?

If yes: I get the internal server error: Class 'Doctrine\_Query' not found in ... on line ...

I searched for a file which contains the string 'Doctrine\_Query', but I haven't such a file. So where do I find this class?
