para definir como devolver resultados se tiene

---

$q = Doctrine_Query::create()

   ->from('Post p')

   ->setHydrationMode(Doctrine::HYDRATE_ARRAY);

$resultSet = $q->execute(); // $resultSet is an array

foreach ($resultSet as $post) {

    // $post is an array

    echo $post['title'];

}

---

$q = Doctrine_Query::create()

   ->from('Post p')

   ->setHydrationMode(Doctrine::HYDRATE_RECORD); // Unnecessary, HYDATE_RECORD is default method

$resultSet = $q->execute(); // $resultSet is an Doctrine_Collection object

foreach ($resultSet as $post) {

    // $post is an Post object

    echo $post->getTitle();

    echo $post['title']; // Each Doctrine's Model object implements ArrayAccess interface so this is possible

    echo $post->myCustomMethod();

}

$q = Doctrine_Query::create()

   ->select('p.created_at')

   ->from('Post p')

   ->where('p.id = ?', 321)

   ->setHydrationMode(Doctrine::HYDRATE_SINGULAR_SCALAR); 

$createdAt = $q->execute();
