How to perform a simple SELECT with doctrine?

Select * from tableName order by id desc limit 10

How to perform something like the above with doctrine by a demo?

Inside the model's Table class (eg tableNameTable.class.php):

function getResults()
{
  $results = self::createQuery("q")
    ->select("q.*")
    ->orderBy("q.id DESC")
    ->limit(10)
    ->execute();

  return $results;
}

will give you a Doctrine Collection of results.
