select *         


        

Answer 1

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);
