Doctrine Native query inside query builder join - symfony

I am working on a query on Doctrine 2 (with Symfony 2.8)
I have this query giving me relevant info:
$qb = $this->createQueryBuilder('ea');
$qb->join('ea.entity_b', 'eb')
->join('ea.entity_c', 'ec')
->join('ec.entity_d', 'ed')
->join('MainBundle:Entity_E', 'ee','WITH', 'ee.column1 = ea.id')
->join('MainBundle:Entity_F', 'ef', 'WITH', 'ea.column1 = ef.id');
Now, I need to add extra info to that query, but it comes from a native SQL, something like this:
SELECT * FROM DS ORDER BY id DESC LIMIT 1
And make sure that the id of the result from the native query is equal to ef.id
I hope I made any sense.
Thanks

Do you know DQL ?
Similar to SQL but adapted for Doctrine.
http://docs.doctrine-project.org/projects/doctrine-orm/en/latest/reference/dql-doctrine-query-language.html
You can then do queries like :
<?php
$query = $em->createQuery("SELECT u FROM User u JOIN u.address a WHERE a.city = 'Berlin'");
$users = $query->getResult();

Convert SQL into Doctrine 2 QueryBuilder

I need help to convert a valid SQL query into createQueryBuilder. The problem I have is I don't know how to LEFT JOIN on a SELECT in the createQueryBuilder.
SELECT username, count(c.user_owner_id) as num_contact, a_g.name as
group_name
FROM `oro_user` as u
INNER JOIN `oro_user_access_group` as u_g on u.id=u_g.user_id
INNER JOIN `oro_access_group` as a_g on u_g.group_id=a_g.id
LEFT JOIN
(SELECT cc.user_owner_id
FROM `orocrm_contact` as cc
INNER JOIN`orocrm_contact_to_contact_grp` as cc_g on cc_g.contact_id=cc.id
INNER JOIN `orocrm_contact_group`
as c_g on cc_g.contact_group_id=c_g.id
WHERE c_g.label='New One' and cc.semester_contacted='2017A')
as c on u.id=c.user_owner_id
WHERE a_g.name='Full-timer' and u.enabled = 1 and u.gender='male'
GROUP BY u.id
ORDER BY num_contact
I have two queries below, I want user to LEFT JOIN the results from contact
$user = $this->em->getRepository('OroUserBundle:User')->createQueryBuilder('u')
->select('u.username')
->innerJoin('u.groups','g')
->andWhere('g.name = :group')
->setParameter('group', 'Full-timer')
->getQuery();
$contacts = $this->em->getRepository('OroContactBundle:Contact')->createQueryBuilder('c')
->select('c')
->innerJoin('c.groups','g')
->andWhere('g.label = :group')
->andWhere('c.semester_contacted = :sem')
->setParameter('group', 'New One')
->setParameter('sem', '2017A')
->setMaxResults(1)
->getQuery();
This is a pretty complex queries and since the ORM QueryBuilder works closer to your entities than the database I'm not sure if you can just "dump" the DQL into a ->join(). The good news with the DBAL QueryBuilder that works:
$dbalQueryBuilder
->from('user_table as u')
...
->join('u', '('.$otherDbalQueryBuilder->getSQL().')', 'c')
This is from memory so it might be a little different, but something like that.
With that you can get all the fields you require, but you won't get any entities. Luckily Doctrine provides ways to build entities from Native SQL using ResultSetMapping.
$userWithContacts = $entityManager->createNativeQuery(
$dbalQueryBuilder->getSQL(),
$yourResultSetMapping
);
I know this is will require more code and is probably not as nice as just using the ORM QueryBuilder, but I find it oftentimes to be the best way to deal with existing queries that need to be ported to ORM somehow.

Doctrine query builder - nested queries, AS keyword, select functions

SELECT t1.field1 AS foo, (SELECT ABS(SUM(amount)) FROM table2 t2) FROM table1;
How can I convert this query into symfony 2 doctrine query builder?
$results = $this->getEntityManager()->createQueryBuilder()
->select(...)
//...
$results = $this->getEntityManager()->createQueryBuilder()
->select('t1.field1')
->addSelect('abs(sum(amount)) t2')
->from('BundleName:Entity', 't1)
->leftJoin('t1.field', 'another')
->getQuery()->getResult();
Maybe this works, I found a similar problem and a solution here:
Select Subquery with COUNT() in Doctrine DQL
Or if it not works, you can create two queries for the problem, and you use the first query's result in the second query.

Symfony 1.4 Doctrine update with inner join

I'm going to write MySQL query like follow query in doctrine.
UPDATE vehicle a
INNER JOIN vehicle b ON a.id = b.id
SET a.total_view = b.total_view+1
WHERE a.id=1;
I tried in doctrine like follow. But it doesn't work.
Is there any solution for that ?
$q = Doctrine_Query::create()
->update('Vehicle v')
->innerJoin('v.Vehicle v2')
->set('v.total_view = v2.total_view+1')
->where('v.id = ?',$id);
return $q->execute();
From what I recall in a past project, you just can't because it is not supported. You have to do it manually with native sql like this

update doctrine with join table

I am trying to update the field "note" in Note Entity which have a relation ManyToOne (bidirectionnel) with "ElementModule" and "Inscription", the entity "Inscription" have a relation ManyToOne with the "Etudiant" Entity
I tried this DQL Query:
$query = $this->_em->createQuery('update UaePortailBundle:Note u JOIN u.inscription i JOIN u.elementmodule e join i.etudiant et set u.note = ?3
where et.id = ?1 and e.id = ?2 ');
$query->setParameter(1, $etudiant);
$query->setParameter(2, $element);
$query->setParameter(3, $note);
$resultat = $query->execute();
i get this error
[Syntax Error] line 0, col 50: Error: Expected Doctrine\ORM\Query\Lexer::T_EQUALS, got 'i'
LEFT JOIN, or JOINs in particular are only supported in UPDATE statements of MySQL. DQL abstracts a subset of common ansi sql, so this is not possible. Try with a subselect or IDENTITY ( you must use the latest version of Doctrine 2.2.2 ) :
createQuery('update UaePortailBundle:Note u set u.note = ?3
where IDNETITY(u.inscription) = ?1 and IDENTITY(u.elementmodule) = ?2 ');
after searching and trying to find a solution for that using doctrine dql, i was not able to find it, so i used direct sql query to update the database.
$stmt = $this->getEntityManager()
->getConnection()
->prepare("update note set note = :note where `etudiant_id` like :etudiant_id and `elementmodule_id` like :elementmodule_id");
$stmt->bindValue('etudiant_id',$etudiant);
$stmt->bindValue('elementmodule_id' ,$element );
$stmt->bindValue('note', $note);
$stmt->execute();

Query with EXISTS for Doctrine Symfony2

How can I implement the following query with Query Builder?
SELECT *
FROM t
WHERE t.status = 1
OR EXISTS(SELECT *
FROM r
WHERE r.t_id = t.id
AND r.status = 1
)
The part without exist check is easy, but is there a way to implement the EXISTS?
You either need to use two query builders:
$queryBuilder->expr()->exists($subQueryBuilder->getDql());
or use DQL directly:
$queryBuilder->expr()->exists('SELECT *
FROM r
WHERE r.t_id = t.id
AND r.status = 1'
);
You'll find more examples in the docs: http://www.doctrine-project.org/projects/doctrine-orm/en/current/reference/query-builder.html
