Actually, i would like to reproduce with Doctrine this regular SQL Query :
SELECT SUM(b.nb_places * (SELECT pricing FROM param p WHERE t.date BETWEEN p.from_date AND p.to_date)) as gains from booking b INNER JOIN tour t ON b.tour_id = t.id;
That compute total gains according prices between two dates.
I wrote this DQL in a Repository :
public function allBooking() {
$query = $this->manager->createQuery(
'SELECT
SUM(b.nbPlaces * SELECT p.pricing FROM \App\Entity\Param p WHERE t.date BETWEEN p.fromDate AND p.toDate)
FROM App\Entity\Booking b JOIN b.tour t'
);
return $query->getResult();
}
But running this query, i got :
[Syntax Error] line 0, col 24: Error: Expected Literal, got 'SELECT' (500 Internal Server Error)
How do i acheive this query with DQL or using QueryBuilder ?
Thx for help
You forgot about putting
SELECT p.pricing FROM \App\Entity\Param p WHERE t.date BETWEEN p.fromDate AND p.toDate
into additional brackets.
It should looks like this:
$query = $this->manager->createQuery(
'SELECT SUM(b.nbPlaces * (SELECT p.pricing FROM \App\Entity\Param p WHERE t.date BETWEEN p.fromDate AND p.toDate))
FROM App\Entity\Booking b JOIN b.tour t'
);

I got a working SQL query : select p.name, p.id from acv_project p join acv_product prod on prod.project_id = p.id where prod.weight <> 0 and p.green_user_id = 18
If i pass it into a `
$stmt = $em->getConnection()->prepare($rawSql);
$stmt->execute([]);
$projects = $stmt->fetchAll();
It works but i'd like to pass it by adding the "green_user_id" as a parameter and not always 18.
When i try with this code : `
$sql2 = "select p from ArtoAcvBundle:Project p join prod ArtoAcvBundle:Product on prod.project_id = p.id where prod.weight <> 0 and p.green_user_id =:userId";
$query2 = $em->createQuery($sql2)->setParameters(
array('userId' => $userId));
$projects = $query2->getResult();
I get [Semantical Error] line 0, col 48 near 'ArtoAcvBundle:Product': Error: Identification Variable prod used in join path expression but was not defined before.
And with QueryBuilder, i tried lots of thing but fails to understand how to write it.
Here are some links to my 2 Doctrine entities :
Entity Product
Entity Project
Thanks for help !
Proof with:
$sql2 = "select p from ArtoAcvBundle:Project p join ArtoAcvBundle:Product prod where prod.weight <> 0 and p.green_user_id =:userId";
Yep, great thanks for having found this solution. I continued to search and find there existed a bindValue() method in Doctrine.
So i passed my parameter with the raw SQL modified and it works
Example with QueryBuilder
// select p from ArtoAcvBundle:Project p join prod ArtoAcvBundle:Product on prod.project_id = p.id where prod.weight <> 0 and p.green_user_id =:userId
$query = $this->getRepository(Project::class)->createQueryBuilder('p');
$query->join('p.products' , 'prod')
->andWhere('prod.weight <> 0')
->andWhere('p.greenUser = :user')
->addParameter('user', $youruserEntity);
return $query->getQuery()->getResult();
Goal: Ordering my entities on how ofter they are used on associated relations (oneToMany)
The problem: DQL, it somehow handles the FROM keyword is an entity or class.
The Exception thrown: QueryException: [Semantical Error] line 0 col 103 near 'FROM MyBundle:Entity Error: Class 'FROM' is not defined.
Here is a SQL query I wrote to test how to get the data. It works perfectly
SELECT en.id, (COUNT(DISTINCT ag.artist_id) + COUNT(DISTINCT rg.release_id) + COUNT(DISTINCT tg.track_id)) AS total
FROM myapp.entity AS en
LEFT JOIN myapp.other_one AS o1 ON o1.entity_id = en.id
LEFT JOIN myapp.other_two AS o2 ON o2.entity_id = en.id
GROUP BY en.id
ORDER BY total DESC ;
To get the data in symfony to hydrate to objects I try to use Doctrine Query Language in the EntityRepository like this:
/**
* Find Most Common Entities
*
* #return array
*/
public function findMostCommon()
{
$em = $this->getEntityManager();
$qb = $em->createQueryBuilder();
$qb
->select('en, (COUNT(DISTINCT en.other1) + COUNT(DISTINCT en.other2)) AS count')
->from('MarulaBundle:Entity', 'en')
->leftJoin('MyBundle:Other1', 'o1', 'WITH', 'o1.entity = en.id')
->leftJoin('MyBundle:Other2', 'o2', 'WITH', 'o2.entity = en.id')
->groupBy('en')
->orderBy('count', 'DESC')
;
return $qb->getQuery()->getResult();
}
Since it is possible in a SQL query. I was hoping it would work just as fine with DQL.
Has anyone experienced this error before? Is it even possible to achieve this with Doctrine, or is doctrine limited relating this issue?
OOPS: I should not use the keyword "count"
Solution:
->select('en, (COUNT(DISTINCT en.other1) + COUNT(DISTINCT en.other2)) AS HIDDEN orderCount')
note: adding the HIDDEN keyword helps to get only the entities back, which makes the hydration fit right in
I have a Product Entity which has a ManyToMany relationship with a Taxon Entity. I want to find all the products that belong to the intersection of all Taxons. For instance I want to find all products that belong to taxons with IDs 1 and 2.
Products
{1,2,3}
Taxons
{1,2,3,4,5}
ProductsToTaxons
{{p1,t1},{p1,t2}, {p2,t2}}
I want to retrieve the following set ONLY when querying products for taxons 1 and 2:
Product
{1}
which is from {{p1,t1}, {p1,t2}}
Okay, So here is the DQL that i tried... but it doesn't work?
SELECT p FROM SRCProductBundle:Product p
JOIN p.taxons t
WHERE t.id = 1 AND t.id = 2
(P.S. I would also do this with QueryBuilder with as well)
EDIT
To clarify, here is the SQL that I would like to translate into DQL/QueryBuilder.
select p.id
from product p
where exists (select product_id
from product_to_taxon
where taxon_id = 1
and product_id = p.id)
and exists (select product_id
from product_to_taxon
where taxon_id = 4
and product_id = p.id);
You can use the MEMBER OF statement to achieve this although in my experience it hasn't produced very performant results with a ManyToMany relationship:
In DQL:
SELECT p FROM SRCProductBundle:Product p
WHERE 1 MEMBER OF p.taxons OR 2 MEMBER OF p.taxons
Or with Query builder
$this->createQueryBuilder('p')
->where(':taxon_ids MEMBER OF p.taxons')
->setParameter('taxon_ids', $taxonIdsArray)
->getQuery()
->getResult();
This will create SQL similar to the example provided although in my experience it still had a join in the EXISTS subqueries. Perhaps future versions of Doctrine can address this.
I think you want something like this:
$qb = $this
->createQueryBuilder('p')
->select('p.id')
;
$qb
->leftJoin('p.taxons', 'taxon1', Join::WITH, 'taxon1.id = :taxonId1')
->setParameter('taxonId1', 1)
->andWhere($qb->expr()->isNotNull('taxon1'))
->leftJoin('p.taxons', 'taxon2', Join::WITH, 'taxon2.id = :taxonId2')
->setParameter('taxonId2', 2)
->andWhere($qb->expr()->isNotNull('taxon2'))
;
Which is equivalent to the SQL:
SELECT p.id
FROM products p
LEFT JOIN taxons t1 ON (p.id = t1.product_id AND t1.id = 1)
LEFT JOIN taxons t2 ON (p.id = t2.product_id AND t2.id = 2)
WHERE t1.id IS NOT NULL
AND t2.id IS NOT NULL
;
Your DQL has wrong logic. You can't have a taxon with both id=1 and id=4. You could do it like this:
SELECT p FROM SRCProductBundle:Product p
JOIN p.taxons t
WHERE t.id = 1 OR t.id = 4
But I would prefer this way:
SELECT p FROM SRCProductBundle:Product p
JOIN p.taxons t
WHERE t.id IN (1, 4)
Using query builder that would look something like this, assuming you're in EntityRepository class:
$this->createQueryBuilder('p')
->join('p.taxons', 't')
->where('t.id IN :taxon_ids')
->setParameter('taxon_ids', $taxonIdsArray)
->getQuery()
->getResult();
For lack of a clean way to do this with DQL, and after a considerable amount of research, I resorted to doing this in Native SQL. Doctrine allows Native SQL via the EntityManager with createNativeQuery().
So in short, I utilized this ability and constructed the SQL query included in my question as a string and then passed it to the createNativeQuery() function.
This does appear to have some drawbacks as it appears I will be unable to use the KnpPaginatorBundle with it... So I might end up just filtering the results in PHP rather than SQL, which I'm hesitant to do as I think there are performance drawbacks.
I'm trying to use this query:
MySQL SELECT DISTINCT by highest value
SELECT
p.*
FROM
product p
INNER JOIN
( SELECT
magazine, MAX(onSale) AS latest
FROM
product
GROUP BY
magazine
) AS groupedp
ON groupedp.magazine = p.magazine
AND groupedp.latest = p.onSale ;
Within Symfony2 and DQL.
I have:
$query = $em->createQuery("SELECT p FROM MyBundle:Product p WHERE p.type = 'magazine' AND p.maglink IS NOT NULL OR (p.type = 'magazine' AND p.diglink IS NOT NULL) GROUP BY p.magazine ORDER BY p.onSale DESC");
Which works fine with and outputs objects but without the correct MAX(onSale)
Doing:
$query = $em->createQuery("SELECT p , MAX(p.onSale) FROM MyBundle:Product p WHERE p.type = 'magazine' AND p.maglink IS NOT NULL OR (p.type = 'magazine' AND p.diglink IS NOT NULL) GROUP BY p.magazine ORDER BY p.onSale DESC");
Results in non-objects being returned.
This:
$query = $em->createQuery("SELECT
p.*
FROM
MyBundle:Product p
INNER JOIN
( SELECT
p.magazine, MAX(onSale) AS p.latest
FROM
MyBundle:Product p
GROUP BY
p.magazine
) AS groupedp
ON groupedp.magazine = p.magazine
AND groupedp.latest = p.onSale ;");
Throws this error:
[Semantical Error] line 0, col 127 near 'SELECT
': Error: Identification Variable ( used in join path expression but was not defined before.
I assume due to this Symfony2 Doctrine query
How can I maintain my mapping while still being able to sort each item by onsale?
Have you considered splitting this into two queries:
First:
Run your query directly against the database connection, and return the IDs of the relevant rows, in the order you want. This separates your complex query from DQL.
Second:
Query the rows through Doctrine to get the full entities you want, based on the IDs/orders of the previous query.
This is a shot in the dark, but it seems fairly obvious. Your aliasing two tables to the same alias. Thus when your using p. in the join it thinks your working from the original definition of p from before the join, then you alias the join as p. Change the alias of the join (and the references to that table) so each alias is unique.
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();
