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()!

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);
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'm trying to run this query on Propel 1.6 with symfony 1.4.20.
I want to bind 2 parameters onto this subquery but its not working.
$paginas = PaginaQuery::create()
->where("pagina.id not in (select id from cliente_artista where cliente_artista.cliente_id = ? and cliente_artista.culture = ?)"
,array('XXX', 'en')
)
->limit(5)
->find();
This gives me the error:
Cannot determine the column to bind to the parameter in clause
I also found this post but there is no answer (https://groups.google.com/forum/?fromgroups=#!topic/propel-users/2Ge8EsTgoBg)
Instead of using placeholders. You may use $id and $culture:
//first, get an array of the id's
//define your vars
$id = $your_id_param;
$culture = 'en';
$cliente_artistas = ClienteArtistaQuery::create()
->select('id')
->distinct()
->filterByClienteId($id)
->filterByCulture($culture)
->find();
$paginas = PaginaQuery::create()
->where("pagina.id NOT IN ?", $cliente_artistas)
->limit(5)
->find();
If this has to be done in one query, recommend using raw sql and binding the parameters into the PDO statement (but then you lose the convenience of PropelObjectCollections):
public function getResultSet($id, $culture) {
$id = $id_param;
$culture = $culture_param;
$sql = <<<ENDSQL
SELECT * from pagina
WHERE id NOT IN (SELECT distinct id
FROM cliente_artista
WHERE cliente_id = ?
AND culture = ?
)
LIMIT 5
ENDSQL;
$connection = Propel::getConnection();
$statement = $connection->prepare($sql);
$statement->bindValue(1, $id);
$statement->bindValue(2, $culture);
$statement->execute();
$resultset = $statement->fetchAll(PDO::FETCH_ASSOC); // or whatever you need
if (! count($resultset) >= 1) {
// Handle empty resultset
}
return $resultset;
}
You could also write some query methods to use propel orm query methods. Ofcourse, the propel api is beneficial reference. There are several ways to do this. I have indicated one method here which should work for you.
EDIT:
Here's an idea on doing this as one query [since useSelectQuery() requires 'relation' name], this idea assumes tables are not related but that id's are:
$paginas = PaginaQuery::create()
->addJoin(PaginaPeer::ID, ClienteArtistaPeer::CLIENTE_ID, Criteria::LEFT_JOIN)
->where("ClienteArtista.Id <> ?", $id)
->where("ClienteArtista.Culture <> ?", $culture)
->select(array('your','pagina','column','array'))
->limit(5)
->find();
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 am trying to get records from a table where patentgroup_id is null. I tried this
$repository = $this->getDoctrine()->getRepository('MunichInnovationGroupPatentBundle:SvPatents');
$qb1 = $repository->createQueryBuilder('sv')
->select('sv')
->where('sv.patentgroup = :patentgroup')
->setParameter('patentgroup', null)
->getQuery();
$nogroup_patents = $qb1->getArrayResult();
var_dump($nogroup_patents);
There is one record in the table whose patentgroup_id is null but I am getting empty array.
Any ideas? What I am doing wrong
thanks
same way you would do it in SQL
->where('sv.patentgroup IS NULL')
