How to run raw SQL Query with Zend Framework 2

Question

Is there a way to execute a SQL String as a query in Zend Framework 2?

I have a string like that:

$sql = \"SELECT * FROM testTable WHERE myColumn = 5

If you have EntityManager $em on your hands, you can do something like this:

   $select = $em->getConnection()->executeQuery("
        SELECT a.id, a.title, a.announcement, asvc.service_id, COUNT(*) AS cnt,
            GROUP_CONCAT(asvc.service_id SEPARATOR \", \") AS svc_ids
        FROM article AS a
        JOIN articles_services AS asvc ON asvc.article_id = a.id
        WHERE
        asvc.service_id IN (
            SELECT tsvc.service_id
            FROM tender AS t
            JOIN tenders_services AS tsvc ON tsvc.tender_id = t.id
            WHERE t.id = :tenderId
        )
        GROUP BY a.id
        ORDER BY cnt DESC, a.id DESC
        LIMIT :articlesCount
    ", [
        'articlesCount' => 5,
        'tenderId' => $tenderId,
    ], [
        'articlesCount' => \PDO::PARAM_INT,
    ]);

    $result = $select->fetchAll(); // <-- here are array of wanted rows

I think this way to execute complex queries is best for Zend. But may be I'm not very smart in Zend still. Will glad to see if it helps to someone.
