How to write union query in doctrine?

I want to use union in doctrine, i searched a lot but didn't get any success, this is my union query in sql, how to convert this query in doctrine?

select * from (select orderid,tutorialId,points,allow_multiple,question,answer1,image1,correct1,answer2,image2,correct2,answer3,image3,correct3,answer4,image4,correct4,answer5,image5,correct5,'1' as istest,'' as content,'' as media,'' as media_type_id from tutorial_test

union

select orderid,tutorialId,'0' as istest,content,media,media_type_id,'' as points,'' as allow_multiple,'' as question,'' as answer1,'' as image1,'' as correct1,'' as answer2,'' as image2,'' as correct2,'' as answer3,'' as image3,'' as correct3,'' as answer4,'' as image4,'' as correct4,'' as answer5,'' as image5,'' as correct5 from tutorial_elements) a where a. tutorialId = 1 order by orderid asc


AND this one is my doctrine query

$query = "SELECT * FROM(SELECT
tt.tutorialid
FROM
TutorialTest tt
UNION
SELECT te.tutorialid) tte
WHERE tte.tutorialid = 1

";
$qb = $this->Doctrine->createQuery($query);
$tutorial_test = $qb->getResult();


i researched alot but didn't get any success, if any one can help, million of thanks in advance fot that.

Answer

Well i have found a solution

We can use this query with RSM as following

"Usman is basically table name and class"

    $rsm = new ResultSetMapping();
    $rsm->addEntityResult('Usmans', 'u');
    $rsm->addFieldResult('u', 'orderid', 'orderid');
    $rsm->addFieldResult('u', 'tutorialId', 'tutorialid');
    $rsm->addFieldResult('u', 'points', 'points');

    $query = $this->Doctrine->createNativeQuery('SELECT * FROM usman', $rsm); 
    $tutorial_tests = $query->getResult();

AND we can use without ORM as

$testQuery = "
    select * from (
            select orderid, 
                tutorialId, 
                points, 
                allow_multiple, 
                question, 
                answer1, 
                image1, 
                correct1, 
                answer2, 
                image2, 
                correct2, 
                answer3, 
                image3, 
                correct3, 
                answer4, 
                image4, 
                correct4, 
                answer5, 
                image5, 
                correct5, 
                '1' as istest, 
                '' as content, 
                '' as media, 
                '' as media_type_id 
            from tutorial_test

            union

            select orderid, 
                tutorialId, 
                '0' as istest, 
                content, 
                media, 
                media_type_id, 
                '' as points, 
                '' as allow_multiple, 
                '' as question, 
                '' as answer1, 
                '' as image1,
                '' as correct1,
                '' as answer2,
                '' as image2,
                '' as correct2,
                '' as answer3,
                '' as image3,
                '' as correct3,
                '' as answer4,
                '' as image4,
                '' as correct4,
                '' as answer5,
                '' as image5,
                '' as correct5  
            from tutorial_elements
        ) a 
        where a. tutorialId = $tutorial_id 
        order by orderid asc
";

$resultSets = $this->Doctrine->getConnection()->fetchAll($testQuery);
