Each Disque (d) has an associated collection of Note (n).
My querybuilder is to get every Disque based on how many Note are associated.
Here's a peak on the classes
class Disque
{
...
/**
* #ORM\ManyToMany(targetEntity="Note", cascade={"persist"})
*/
private $notes;
...
}
class Note
{
...
/**
* #ORM\ManyToOne(targetEntity="NoteValeur", cascade={"persist"})
* #ORM\JoinColumn(nullable=true)
*/
private $noteValeur;
...
}
class NoteValeur
{
...
/**
* #Gedmo\Slug(fields={"titre"})
* #ORM\Column(name="slug", unique=true, length=32)
*/
private $slug;
}
I'm using Doctrine Querybuilder to fetch the results, using a count for setting the threshold.
<?php
...
class DisqueRepository extends \Doctrine\ORM\EntityRepository
{
public function getDisquesByNotesAndAllInfo($slug, $seuil, $page, $nbPerPage)
{
$q = $this->createQueryBuilder('d');
$q
->select('d as infosDisque')
->leftJoin('d.pochettes', 'p')
->addSelect('p')
->leftJoin('d.groupes','g')
->addSelect('g')
->leftJoin('d.labelDisque', 'l')
->addSelect('l')
->leftJoin('d.chroniques','c')
->addSelect('c')
->leftJoin('d.notes', 'n')
->addSelect('n')
->innerJoin('n.noteValeur','nv')
->addSelect('nv')
->groupBy('d')
->addSelect('COUNT(d) as NbNotes')
->where('nv.slug LIKE :slug')
->setParameter('slug', $slug)
->having($q->expr()->gte('NbNotes',':seuil'))
->setParameter('seuil', $seuil)
->setFirstResult( ($page-1) * $nbPerPage)
->setMaxResults($nbPerPage)
->orderBy('d.dateSortieDisque', 'desc')
;
return new Paginator($q, true);
}
}
The result set is perfectly fine. The problem is that when I change the $page value, the offset in the SQL is not increased. I'm getting the same range of results no matter what.
The Symfony profiler gives me the following executable query
SELECT DISTINCT id_44

ORDER BY datesortiedisque_3 DESC LIMIT 10 OFFSET 10
I can't seem to change the offset in this query no matter what I pass to the $q->setFirstResult() method.
Does anybody have a clue ?
Well, guess what, I was using a debug value in my controller and I had forgotten about it :
$disques = $dr->getDisquesByNotesAndAllInfo($slug, $seuil, 2, $nbPerPage);
All works fine now that I changed back this messy "2" value.
Sorry about that. Thanks to both of you for your help !

I have native sql query with left join when have on with or condition, how to represent it in query builder ?
$query = " SELECT te.id
FROM task_executions AS te
INNER JOIN tasks AS t ON t.id = te.task_id
LEFT JOIN cost_objects AS co ON co.id = t.cost_object_id
LEFT JOIN cost_object_managers AS com ON com.cost_object_id = co.id OR com.cost_object_id = co.parent_id
and I need represent it in query builder. But in User entity I have ManyToMany relation, without separate table and when I try left join WITH condition this is not same what I need. I need change relation for ON
LEFT JOIN cost_object_managers AS com ON com.cost_object_id = co.id OR com.cost_object_id = co.parent_id
User entity
class User
{
...
/**
* #ORM\ManyToMany(targetEntity="CostObject", mappedBy="users")
*/
private $costObjects;
}
CostObject entity
class CostObject
{
/**
* #var CostObject
*
* #ORM\ManyToOne(targetEntity="CostObject", inversedBy="children")
* #ORM\JoinColumns({

* )
*/
private $users;
and my query builder without condition
$qb->select('te')
->from('AppBundle:TaskExecution', 'te')
->innerJoin('te.task', 't')
->leftJoin('t.costObject', 'co')
->leftJoin('co.users', 'com')
this is $query->getSQL()
SELECT some_name FROM task_executions t0_ INNER JOIN tasks t1_ ON t0_.task_id = t1_.id LEFT JOIN cost_objects c2_ ON t1_.cost_object_id = c2_.id LEFT JOIN cost_object_managers c4_ ON c2_.id = c4_.cost_object_id LEFT JOIN users u3_ ON u3_.id = c4_.user_id ORDER BY t0_.execution_start DESC
In this example I see ON relation condition LEFT JOIN users u3_ ON u3_.id = c4_.user_id. And need change it like in native sql
Now I have
$qb->select('te')
->from('AppBundle:TaskExecution', 'te')
->innerJoin('te.task', 't')
->leftJoin('t.costObject', 'co')
->leftJoin(
'co.users',
'com',
Join::ON,
$qb->expr()->orX(
'co = com.costObjects',
'co.parent = com.costObjects'
)
)
but got error
[Syntax Error] line 0, col 112: Error: Expected end of string, got 'ON'
if I used WITH condition, in my sql represent I still have relation by id, I don't need that
->leftJoin(
'co.users',
'com',
Join::WITH,
$qb->expr()->orX(
'co MEMBER OF com.costObjects',
'co.parent MEMBER OF com.costObjects'
)
)
LEFT JOIN users u3_ ON u3_.id = c4_.user_id AND (EXISTS (SELECT 1 FROM cost_object_managers c5_ INNER JOIN cost_objects c6_ ON c5_.cost_object_id = c6_.id WHERE c5_.user_id = u3_.id AND c6_.id IN (c2_.id)) OR EXISTS (SELECT 1 FROM cost_object_managers c5_ INNER JOIN cost_objects c6_ ON c5_.cost_object_id = c6_.id WHERE c5_.user_id = u3_.id AND c6_.id IN (c2_.parent_id)))
I mean users u3_ ON u3_.id = c4_.user_id AND but in native query we have only LEFT JOIN cost_object_managers AS com ON com.cost_object_id = co.id OR com.cost_object_id = co.parent_id
How it's reproduce in Query Builder with ON condition type?
If you have the query and it works for you, you don't need to do all the work to transform it to DQL or the QueryBuilder programmatic syntax. You can just use Doctrine's Native Query and then - if needed - map the result to your object. Just create a custom repository and in it a new method that roughly looks like this:
public function findTaskExecutionBy...()
{
$query = $this->entityManager->createNativeQuery('SELECT te.id FROM ...');
return $query->getSingleScalarResult(); // If it's just one id you expect
}
You can also use $query->getResult() if you expect multiple id's to be returned. Or use the ResultSetMapping if you want the whole Task-object:
$rsm = new ResultSetMappingBuilder($this->entityManager);
$rsm->addRootEntityFromClassMetadata('App\Entity\Task', 'te');
$query = $this->entityManager->createNativeQuery(
'SELECT te.* FROM ...',
You can also check the Doctrine documentation for a more detailed explanation and some more examples: http://docs.doctrine-project.org/projects/doctrine-orm/en/latest/reference/native-sql.html
$rsm
);
I have Many to Many relationship between Institutes and Courses. I want to build query that returns only the institutes list whom some courses has been assigned. I have wrote queries in this situation for one to many. but for not many to many. here is the relationships,
class Institutes {
/**
* #ORM\ManyToMany(targetEntity="Courses", inversedBy="institutes")
* #ORM\JoinTable(name="institute_courses",
* joinColumns={#ORM\JoinColumn(name="institute_id", referencedColumnName="id")},
* inverseJoinColumns={#ORM\JoinColumn(name="course_id", referencedColumnName="id")}
* )
*/
protected $courses;
}
class Courses {
/**
* #ORM\ManyToMany(targetEntity="Institutes", mappedBy="courses")
*/
protected $institutes;
}
here is the query that i have written, but didn't work properly.
$repository->createQueryBuilder('s')
->leftJoin('CoursesBundle:Courses','c', 'ON c.institutes = s.courses')
->where('s.active = :active')
->andWhere('s.verified = :active')
->setParameter('active', true)
->orderBy('s.name', 'ASC');
This should do the trick:
$repository->createQueryBuilder('i')
->innerJoin('i.courses','c')
->where('i.active = TRUE')
->andWhere('i.verified = TRUE')
->orderBy('i.name', 'ASC');
You can use a JOIN as you would with other kinds of associations. The following query will find all courses which have been assigned at least to one institute:
SELECT c FROM SomeBundle:Courses c JOIN c.institutes i
You can filter the results further by adding a join condition:
SELECT c FROM SomeBundle:Courses c JOIN c.institutes i WITH i.something = :someParam
I have 2 classes that I want to select from DB using 1 query in Symfony2 Doctrine.
The first entity is Calculation and the second is Polynomial. They have 1:1 relationship:
/**
* Acme\UserBundle\Entity\Calculation
*
* #ORM\Table(name="Calculation")
* #ORM\Entity(repositoryClass="AppBundle\Entity\CalculationRepository")
*/
class Calculation {
//...
/**
* #ORM\OneToOne(targetEntity="Polynomial")
* #ORM\JoinColumn(name="result_polynomial_id", referencedColumnName="id", nullable=false)
**/
private $resultPolynomial;
//...
}
I have a query, that returns me all Calculations of one user:
public function findByUser( $user ) {
return $this->getEntityManager()->createQuery(
'SELECT c
FROM AppBundle:User u
JOIN AppBundle:Polynomial p WITH u = p.user
JOIN AppBundle:Calculation c WITH p = c.resultPolynomial
WHERE u = :user
ORDER BY c.id'
)
->setParameter('user', $user)
->getResult();
}
And to the question... Is there a way to get resultPolynomials of the calculations in one query? If I use something like SELECT c, c.resultPolynomial I get error:
[Semantical Error] line 0, col 12 near 'resultPolynomial
': Error: Invalid PathExpression. Must be a StateFieldPathExpression.
And if I use foreach cycle all calculations to get the their resultPolynomials there are many queries to the DB (1 for each calculation) and it is not good for performance if I have many calculations.
I making a guess because you did not post your User definition nor your Polynomial definition.
I think you can make your DQL this way:
SELECT c, p
FROM AppBundle:User u
JOIN u.polynomial p
JOIN p.calculation c
WHERE u = :user
ORDER BY c.id
I guess you already defined your relations in your model so you don't need to repeat it here.
Given this entity
class SystemRecord
{
/**
* #ORM\Id
* #ORM\Column(type="integer", name="ID")
* #ORM\GeneratedValue
* #var int
*/
private $id;
/**
* #ORM\ManyToOne(targetEntity="Application\Entity\User")
* #ORM\JoinColumn(name="USER_SERIAL", referencedColumnName="SERIAL", nullable=false)
* #var User
*/
private $user;
/**
* #ORM\Column(type="utcdatetime", name="DATE_DATA_WAS_FETCHED", nullable=false)
* #var DateTimeInterface
*/
private $dateDataWasFetched;
}
...and this dql
$dql = "
select r
from Application\\Entity\\SystemRecord r
join Application\\Entity\\User u
where r.dateDataWasFetched = (
select max(r2.dateDataWasFetched)
from Application\\Entity\\SystemRecord r2
)
and u.serial = :serial
";
$query = $this->getEntityManager()->createQuery($dql);
$query->setParameter('serial', $user->getSerial());
$sql = $query->getSql();
... I'm hoping to get "the SystemRecords for the user with the specified serial, but only those with the most recent date out of any SystemRecord". In other words, procedurally, "find the most recent date of any SystemRecord for any user. Then find records for the specified user which occurred on that date."
If I were writing sql, I would write
select *
from SYSTEM_RECORDS r
join USER u
on r.USER_SERIAL = u.SERIAL
where DATE_DATA_WAS_FETCHED = (select max(DATE_DATA_WAS_FETCHED) from SYSTEM_RECORDS)
and u.SERIAL = ?
But, doctrine is giving me the following sql
SELECT ...fields from s0_ ...
FROM SYSTEM_RECORDS s0_
INNER
JOIN
USER u1_
ON (s0_.DATE_DATA_WAS_FETCHED = (SELECT max(s2_.DATE_DATA_WAS_FETCHED) AS dctrn__1
FROM SYSTEM_RECORDS s2_) AND u1_.SERIAL = ?)
Which isn't what I want. That gives me "SystemRecords for all users whose SystemRecords have the same date as the most recent SystemRecords for the user with the specified serial".
How do I formulate my query using dql?
If I understand you correctly you need to use a sub query like you did but I think you are missing the in expression. With QueryBuilder you would built the query to get your result like this (I always write my queries with QueryBuilder):
$qb->select(r)
->from('SystemRecord', 'r')
->join('r.user', 'u')
->where(
$qb->expr()->in(
'r.dateDataWasFetched',
"SELECT max(r2.dateDataWasFetched) FROM Application\\Entity\\SystemRecord r2"
)
)
->andWhere('u.serial' = :user_serial)
->setParameter('user_serial', $user->getSerial())
->getQuery()
->getResult();
This answer is based on this answer to similar question on stackoverflow.
EDIT:
If you really want the DQL then you can easily get it from your QueryBuilder instance after building the query using the getDQL method like this:
$dql = $qb->getQuery()->getDQL();
I was able to solve/avoid my problem by avoiding a join
$dql = "
select r
from Application\\Entity\\SystemRecord r
where r.dateDataWasFetched = (
select max(r2.dateDataWasFetched)
from Application\\Entity\\SystemRecord r2
)
and r.user = :user
";
$query = $this->getEntityManager()->createQuery($dql);
$query->setParameter('user', $user);
Resulting sql(correct)
SELECT ...fields from s0_ ...
FROM SYSTEM_RECORDS s0_
WHERE s0_.DATE_DATA_WAS_FETCHED = (SELECT max(s1_.DATE_DATA_WAS_FETCHED) AS dctrn__1
FROM SYSTEM_RECORDS s1_) AND s0_.USER_SERIAL = ?
The notable difference is that instead of specifying the id for the associated entity(via u.serial = :serial, I'm now specifying the entity itself(via r.user = :user). This allows me to omit the join, too. btw - The serial field is tagged with #ORM\Id in my User entity.
However, this is just avoiding the problem. I'm still perplexed by how doctrine interprets the query when a join is present.
Edit - real solution found
Thanks to Wilt, after using the query builder and then using the getDQL() method I found the missing detail. The working dql is
select r
from Application\Entity\SystemRecord r
join r.user u
where r.dateDataWasFetched = (
select max(r2.dateDataWasFetched)
from Application\\Entity\\SystemRecord r2
)
and u.serial = :serial
Note that the difference between the DQL in my original question, and this working solution is join Application\\Entity\\User u vs join r.user u, respectively.
I have the following entity, basically it says a picture has a shop
class InstagramShopPicture
{
/**
* #Exclude()
* #ORM\ManyToOne(targetEntity="InstagramShop", inversedBy="userPictures")
* #ORM\JoinColumn(name="shop_id", referencedColumnName="id", nullable=false, onDelete="CASCADE")
*/
protected $shop;
}
how do I query 10 pictures, each from a unique store in DQL?
So far I have the following:
$query = $em->createQueryBuilder()->select('picture')
->from("ShopiousMainBundle:InstagramShopPicture", 'picture')
->innerJoin('picture.shop', 'shop')
->setMaxResults(10);
;
in other words I just wanted DISTINCT shop, but I am finding it hard to transalate DISTINCT into DQL
UPDATE:
$query = $em->createQueryBuilder()
->select('pictures')
->from("AppMainBundle:InstagramShop", 'shop')
->innerJoin('shop.userPictures', 'pictures')
->innerJoin('pictures.category', 'category')
->innerJoin('category.pictureFirstLevelCategory', 'firstLevelCategory')
->distinct()
;
$query->andWhere('firstLevelCategory = :firstLevelCategory');
$query->andWhere('shop.isLocked = false');
$query->andWhere('shop.expirydate IS NOT NULL');
$query->andWhere('shop.id != :shopId');
$query->andWhere('shop.expirydate >= :currentDate');
$parameter["currentDate"] = new \DateTime('now');
$parameter["shopId"] = $shopId;
$parameter["firstLevelCategory"] = $picture->getCategory()->getPicturefirstlevelcategory()();
I tried doing the above and it gives me this error:
Error: Cannot select entity through identification variables without choosing at least one root entity alias.
UPDATE:
SELECT DISTINCT pictures FROM AppMainBundle:InstagramShop shop INNER JOIN shop.userPictures pictures INNER JOIN pictures.category category INNER JOIN category.pictureFirstLevelCategory firstLevelCategory WHERE firstLevelCategory = :firstLevelCategory AND shop.isLocked = false AND shop.expirydate IS NOT NULL AND shop.id != :shopId AND shop.expirydate >= :currentDate
