I have the following command:
$rsm = new ResultSetMapping();
$query = $this->em->createNativeQuery('SELECT userid FROM prospective_shop WHERE LENGTH(bio) = 0 ORDER BY RAND()', $rsm);
//$query->setMaxResults(10);
$prospectiveShops = $query->getResult();
here it gives me an empty array. I copy pasted that SQL and it worked perfectly fine. Any idea why?
Haven't you forgotten to use:
$rsm->addFieldResult(...);
to map results of the query to the doctrine object?
EDIT:
try this way:
$rsm = new ResultSetMapping();
$rsm->addEntityResult('my\bundle\Entity\ProsprectiveShop', 's');
$rsm->addFieldResult('s','userid','userid');
$query = $this->em->createNativeQuery('SELECT userid FROM prospective_shop s WHERE LENGTH(bio) = 0 ORDER BY RAND()', $rsm);
$prospectiveShops = $query->getResult();

I want to select the average of columns 'note' from a table
'noteparagraphe' where
the id_paragraphe is a parameter ($ref), I tried this query but I'm getting nothing back !
$query=$this->get('doctrine.orm.entity_manager')
->createQuery('Select avg(n.note) from ParagrapheBundle:NoteParagraphe n
WHERE n.id_paragraphe = :idModele');
$query->setParameter('idModele', $ref);
$query->execute();
$avgNote = $query->getResult();
the SQL is : SELECT AVG(note) from note_paragraphe WHERE id_paragraphe=?
Use Query builder:
$query = $this->getDoctrine()->getRepository('ParagrapheBundle:NoteParagraphe');
$avgNote = $query->createQueryBuilder('n')
->select('avg(n.note)')
->where('n.id_paragraphe = :idModele')
->setParameter('idModele', $ref);
->getQuery();
See if that works - I haven't tried it, but I think it should work.
I need to delete all rows where the image_id = x applies
like this
DELETE FROM `ImageVoters` WHERE image_id =1
How do I do this using DQL?
Since im trying to delete several rows at once the remove() function won't work
EntityManager#remove() expects parameter 1 to be an entity object, array given.
$em = $this->getDoctrine()->getManager();
$query = $em->createQuery('SELECT u FROM GabrielUploadBundle:ImageVoters u WHERE u.image_id = 1');
$db_imageactions = $query->getResult();
$em->remove($db_imageactions);
$em->flush();
This is the code that works
$qb = $em->createQueryBuilder();
$qb->delete('GabrielUploadBundle:ImageVoters', 'v')
->where($qb->expr()->eq('v.image_id', ':imageId'))
->setParameter('imageId', $current_imageId);
$qb->getQuery()->execute();
You could create an ORM queryBuilder, to create a clean/safe query object by using internal orm methods
$qb->delete('My\Image\Namespace\ImageVoters', 'ivoter')
->where($qb->expr()->eq('ivoter.image_id', ':imageId')
->setParameter('imageId', 1);
$qb->getQuery()->execute();
You can also execute any raw SQL like this:
$sql = "DELETE FROM ImageVoters WHERE image_id =".$image_id;
$q = $em->getConnection()->exec($sql);
when I run a query with date in where clause, following error is showed...
[Syntax Error] line 0, col 129: Error: Expected known function, got 'DATE_FORMAT'
the query is given below
$query = $this->getEntityManager()->createQuery(
"SELECT a.id, a.amont, a.paymentDescrip, a.paymentType, a.paymentDate
FROM RegalSmsBundle:DailyTransaction a
WHERE DATE_FORMAT(a.paymentDate,'%Y-%m-%d') = :paymentDate
and a.students = :studentId"
)->setParameter('studentId', $studentId)
->setParameter('paymentDate','2013-03-11');
return $query->getResult();
Doctrine doesn't have DATE_FORMAT function defined by default. It's possible to Register Custom DQL Function.
But you can compare date easily (assuming a.paymentDate is of type date):
$query = $this->getEntityManager()->createQuery("
SELECT a.id, a.amont, a.paymentDescrip, a.paymentType, a.paymentDate
FROM RegalSmsBundle:DailyTransaction a
WHERE a.paymentDate = :paymentDate AND a.students = :studentId
")
->setParameter('studentId', $studentId)
->setParameter('paymentDate', new \DateTime('2013-03-11'))
;
return $query->getResult();
Edit: I prefer using querybuider to writing DQL. It would look like this:
$qb = $this->getEntityManager()->getRepository('RegalSmsBundle:DailyTransaction')->createQueryBuilder('a');
$qb
->select('a') // select whole entity
->where($qb->expr()->andX(
$qb->expr()->eq('a.paymentDate', ':paymentDate')
$qb->expr()->eq('a.students', ':studentId')
))
->setParameter('studentId', $studentId)
->setParameter('paymentDate', new \DateTime('2013-03-11'))
;
return $qb->getQuery()->getResult();
Im trying to reproduce this query:
SELECT * FROM `request_lines`
where request_id not in(
select requestLine_id from `asset_request_lines` where asset_id = 1
)
in doctrine query builder,
I am stuck on the where request_id not in(select
I currently have:
$linked = $em->createQueryBuilder()
->select('rl')
->from('MineMyBundle:MineRequestLine', 'rl')
->where()
->getQuery()
->getResult();
You need to use query builder expressions, and this means you need access to the query builder object. Also, the code is easier to write if you generate the subselect list ahead of time:
$qb = $em->createQueryBuilder();
$nots = $qb->select('arl')
->from('$MineMyBundle:MineAssetRequestLine', 'arl')
->where($qb->expr()->eq('arl.asset_id',1))
->getQuery()
->getResult();
$linked = $qb->select('rl')
->from('MineMyBundle:MineRequestLine', 'rl')
->where($qb->expr()->notIn('rl.request_id', $nots))
->getQuery()
->getResult();
It is possible to do this in one Doctrine query:
$qb = $this->_em->createQueryBuilder();
$sub = $qb;
$sub = $qb->select('arl')
->from('$MineMyBundle:MineAssetRequestLine', 'arl')
->where($qb->expr()->eq('arl.asset_id',1));
$linked = $qb->select('rl')
->from('MineMyBundle:MineRequestLine', 'rl')
->where($qb->expr()->notIn('rl.request_id', $sub->getDQL()))
->getQuery()
->getResult();

Using Symfony 5, this solution might help those, who are trying to set parameters on a subquery, the notIn() 2nd argument accepts an array or you could pass a DQL instead and that's what we are doing here and keep in mind that the parameters should be added to the main query as below.
$main = $this->em->createQueryBuilder();
$sub = $main;
$sub = $sub->select('arl')
->from('$MineMyBundle:MineAssetRequestLine', 'arl')
->where($sub->expr()->eq('arl.asset_id',':id'));
$linked = $main->select('rl')
->from('MineMyBundle:MineRequestLine', 'rl')
->where($main->expr()->notIn('rl.request_id', $sub->getDQL()))
->setParameter('id', 1)
->getQuery()
->getResult();
I have a query in the model of my table:
$q = $this->createQuery('a')
->where('a.img1 = null')
->orderBy('a.created_at DESC')
->limit(4);
The thing is that it returns nothing, but in DB there is an entry with no image (img1 field is null). What am I doing wrong? thank you
$q = $this->createQuery('a')
->where('a.img1 IS NULL') // It needs to be IS NULL instead of = null
->orderBy('a.created_at DESC')
->limit(4);
Don't forget ->execute()!
