Как я могу заставить запрос работать с doctrine1 с помощью Symfony 1.4?

Настоящая заслуга принадлежит @Kris Peeling, потому что он привлек мое внимание к этой идее!

Похоже, мне просто нужно было получить массив идентификаторов, поэтому я использовал Doctrine_Manager (PDO) для выполнения работы.

Вот что я сделал, чтобы выполнить свою работу:

if (isset($arrValues['features']) && count($arrValues['features']) > 0) {
  $this->addSearchFeatures($qry, $arrValues);
} else {
  if ($arrValues['no_noise_restrictions']) {
    $subQuery = "SELECT DISTINCT LocationFeatureRestriction.location_id FROM LocationFeatureRestriction WHERE feature_restriction_id = 5";
    $qry->andWhere('q.id NOT IN ('.$subQuery.')');
  }
}

/**
 * Search for venues with selected features
 * @param Doctrine_Query $qry     The SQL query
 * @param array          $values  The form values
 */
protected function addSearchFeatures(Doctrine_Query $qry, array $values = array()) {
  // "Dry" and "Bespoke Hire" options
  $qryParams = array();
  $qryParts = array();

  if (in_array("bespoke_hire", $values["features"]) && $values["features"][array_search("bespoke_hire", $values["features"])]) {
    $qryParts[] = "q.bespoke_hire = :BESPOKE_HIRE";
    $qryParams["BESPOKE_HIRE"] = 1;
    unset($values["features"][array_search("bespoke_hire", $values["features"])]);
  }
  if (array_key_exists("dry_hire", $values["features"]) && $values["features"][array_search("dry_hire", $values["features"])]) {
    $qryParts[] = "q.dry_hire = :DRY_HIRE";
    $qryParams["DRY_HIRE"] = 1;
    $values["features"][array_search("dry_hire", $values["features"])];
  }
  if (count($qryParts)) {
    $qry->andWhere(implode(" OR ", $qryParts), $qryParams);
  }

  // Search for selected features
  if (count($values["features"])) {
    // If anyone need to features should be searched using the OR condition then comment having condtion from following line.

    // When No Noise Restrictions is checked in Licensing Category
    if ($values['no_noise_restrictions']) {
      $subSql = "SELECT DISTINCT location_id FROM location_feature_restriction WHERE feature_restriction_id IN(".implode(',', $values["features"]).") AND location_id NOT IN (SELECT DISTINCT location_id FROM location_feature_restriction WHERE feature_restriction_id = 5)";

      $connection = Doctrine_Manager::connection();
      $statement = $connection->execute($subSql);
      $statement->execute();
      $resultset = $statement->fetchAll(PDO::FETCH_ASSOC);
      $location_ids = array();
      foreach ($resultset as $each) {
        $location_ids[] = $each['location_id'];
      }

      if (count($location_ids)) {
        $qry->andWhere('q.id IN ('.implode(',', $location_ids).')');
      } else {
        $qry->andWhere('q.id IN (0)');
      }
    } else {
      // Otherwise check for the normal features
      $subSql = "SELECT LocationFeatureRestriction.location_id 
                 FROM LocationFeatureRestriction
                 WHERE feature_restriction_id IN(".implode(',', $values["features"]).")
                 GROUP BY location_id
                 HAVING COUNT(DISTINCT feature_restriction_id) = ".count($values['features']);
      $qry->andWhere('q.id IN ('.$subSql.')');
    }

  }
}
