I need to write some complex query builder expression. The sql looks like:
SELECT query,popularity,nb_words
FROM gemini_suggestion
WHERE query IN
(
SELECT * FROM
(
SELECT query
FROM gemini_suggestion
GROUP BY query
HAVING COUNT(query) > 1
) AS subquery
);
The code im stucked at is:
$queryBuilder = $em->createQueryBuilder();
$queryBuilder->select('a')
->from($this->entity['class'], 'a')
->where($queryBuilder->expr()->In('a.query', $subQuery->getDQL()));
$subQuery2 = $em->createQueryBuilder()
->select('b.query')
->from($this->entity['class'], 'b')
->groupBy('b.query')
->having('count(b.query)>1')
;
$subQuery = $em->createQueryBuilder();
$subQuery->select('a')
->from(...)
;
Any help would be nice!
You can try something like this. I'm assuming you have a namespace Entities where you have all your entities classes.
// Subquery to get the queries greater than 1
$subQueryBuilder = $this->entityManager->createQueryBuilder();
$subQueryBuilder->select('gemini_suggestion.query')
->from('Entities\gemini_suggestion', 'gemini_suggestion')
->groupBy('gemini_suggestion.query')
->having($subQueryBuilder->expr()->gt('COUNT(gemini_suggestion.query)', 1));
// Main query where you use the subquery to filter out the records you want
$queryBuilder = $this->entityManager->createQueryBuilder();
$queryBuilder->select('query, popularity, nb_words')
->from('Entities\gemini_suggestion', 'gemini_suggestion')
->where($queryBuilder->expr()->in('gemini_suggestion.query', $subQueryBuilder->getDQL()));
$result = $queryBuilder->getQuery()->getResult();
return $result;

I want to transcribe this sql statement to doctrine format. It was complicated because I don't know how to perform subqueries.
The sentence is as follows:
SELECT * FROM articulo WHERE descripcion = (SELECT descripcion FROM articulo WHERE codigo LIKE 4060981104537)
You can use Doctrine expression API for subqueries.
Example for your query:
you should put following code to Doctrine repository of your articulo entity
$codigo = '4060981104537';
$qb = $this->createQueryBuilder('a');
$qb->where(
$qb->expr()->in(
'a.descripcion',
$this->createQueryBuilder('a2')
->select('a2.descripcion')
->where('a2.codigo LIKE :codigo')
->setParameter('codigo', $codigo)
->getDQL()
)
);
Do sth like this:
$codigo = 4060981104537;
$expr = $em->getExpressionBuilder();
$em->createQueryBuilder()
->select('*')
->from('articulo')
->where(
$expr->in(
'articulo.descripcion',
$em->createQueryBuilder()
->select('*')
->from('articulo', 'secondArticulo')
->where('secondArticulo.codigo LIKE :codigo')
)
->getDQL()
)
)
->setParameter('codigo', $codigo);
And for more info look at this link
I solved it as follows:
$codigo = '4060981104537';
$qb = $this->createQueryBuilder('a2')
->select('a2.descripcion')
->where('a2.codigo LIKE :codigo')
->setParameter('codigo', $codigo);
$descripcion = $qb->getQuery()->getResult();
$qb = $this->createQueryBuilder('m')
->where('m.descripcion= :descripcion')
->setParameter('descripcion', $descripcion);
return $qb->getQuery()->getResult();
How can I generate this query in doctrine or query builder?
SELECT EndDate from helios.fsa_audits order by StartDate desc limit 1;
Any idea or Advice about how to make it?
Seeing your entity here, in your controller you can try this:
$em = $this->getDoctrine()->getManager();
$qb = $em->createQueryBuilder()
->select(array('a'))
->from(FsaAudits::class, 'a')
->orderBy("a.StartDate","DESC")
->setMaxResults(1);
$resultset = $qb->getQuery()->getResult();
if (count($resultset) <= 0) {
$fsaobj = $resultset[0];
echo $fsaobj->getEndDate();
}
See Working with query builder
I have for example two tables: Parent and Children. They have relations many-to-many between each other. Everything is working well, but I don't know how to use where clause in query builder for this.
My code:
$parent = $em->getRepository('AppBundle:Parent')->find(1);
$qb = $em->createQueryBuilder();
$qb->select('c, p')
->from('AppBundle:Children', 'c')
->leftJoin('c.parents', 'p')
->where('p.id = :parent')
->setParameter('parent', $parent)
;
$childrens = $qb->getQuery()->getResult();
This always return me null.
I know - I can use $parent->getChildrens(), but I would like use createQueryBuilder for AppBundle:Children.
How should the where clause look?
I need to count the number of items returned in the subquery. If I write the subquery how DQL - all good, but if I try to build a query via QueryBuilder - I get an error.
Subquery DQL:
$qb3 = $this->createQueryBuilder('c')
->select('COUNT(c.id)')
->where('c.id IN (SELECT cl.id FROM Acme\AppBundle\Entity\ClassC cl INNER JOIN Acme\AppBundle\Entity\ClassP p WHERE p.var1 = :var1 AND p.var2 = cl.id GROUP BY cl.id)')
->setParameter('var1', $var);
Subquery via QueryBuilder:
$qb = $this->createQueryBuilder('c');
$qb->select('COUNT(c.id)')
->where(
$qb->expr()->in(
'c.id',
$this->createQueryBuilder('cl')
->select('cl.id')
->innerJoin('Acme\AppBundle\Entity\ClassP', 'p')
->where('p.var1 = :var1')
->setParameter('var1', $var)
->andWhere('p.var2 = cl.id')
->groupBy('cl.id')
->getDQL()
)
);
Both versions return the same DQL.

Try to move setParameter() to main level of query.
$qb = $this->createQueryBuilder('c');
$qb->select('COUNT(c.id)')
->where(
$qb->expr()->in(

->select('cl.id')

)
->setParameter('var1', $var);
I have a query which looks like below:
SELECT *
FROM mydb.users
left join mydb.job on
users.id = job.userid;
Now I am using doctrine orm in querying database but I am newbie here.
What I have done so far is below but it doesn't work as expected.
$em = $this->getEntityManager();
$qb = $em->createQueryBuilder();
$qb->select(array('a', 'c'))
->from('Admin\Entity\User', 'a')
->leftJoin('a.id', 'c');
$query = $qb->getQuery();
$results = $query->getResult();
return $results;
you do not need the from clause and array from clause select
$em = $this->getEntityManager();
$qb = $em->createQueryBuilder('u');
$qb->select('u', 'j')
->leftJoin('u.jobs', 'j')
$query = $qb->getQuery();
$results = $query->getResult();
return $results;
it is mandatory that your users entity contains a "one to many" jobs for the attribute.
trick to display the SQL output :
var_dump($qb->getQuery()->getSQL());
