I want to use an inner Join for my tables auto and rent('s'). Its an 1:N relationship. If I use ->innerJoin('s', 'a') it comes to some errors like this:
[Semantical Error] line 0, col 62 near 's a, ChrisKfzBuchungBundle:Auto': Error: Class 's' is not defined.
$repo = $this->getDoctrine()->getRepository('ChrisKfzBuchungBundle:Rent');
$qb = $repo->createQueryBuilder('s');
$qb->from('ChrisKfzBuchungBundle:Auto', 'a')
->where('s.mieteStart >= :date_from')
->andWhere('s.mieteEnde <= :date_to')
->setParameter('date_from', $date_from)
->setParameter('date_to', $date_to);
How do I join one ore more tables with queryBuilder?
There are methods for that and also for me it just worked with a configured relation between the two entites. Here are two working examples:
left join:
$query = $repo->createQueryBuilder('s')
->leftJoin(ChrisKfzBuchungBundle:Auto', 'a', 'WITH', 's.id = a.yourJoinCOlumn')
...
inner join:
$query = $repo->createQueryBuilder('s')
->select('s, a')
->innerJoin('s.yourJoinColumn', 'a')
...

I am using Symfony v3.4 branch with Doctrine.
I am having trouble translating SQL query to Doctrine ORM query.
I have 3 tables.
Shop
Firm
User
User --> 1:1 --> Firm --> 1:1 --> Shop
(Symfony developer tool bar reports that associations in tables are made correctly).
I want to get Shop data that corresponds to cretain User in one query.
My SQL, that get a result:
SELECT *
FROM mp2_fos_user as u
LEFT JOIN mp2_firm AS f ON u.id = f.firmUserId
LEFT JOIN mp2_shop AS s ON f.id = s.shopFirmId
WHERE u.id = 1
My Doctrine ORM query
$query = $em->createQueryBuilder()
->select('u, f, s')
->from('App:User', 'u')
->leftJoin('u.userFirm WITH u.id = f.firmUserId', 'f')
->leftJoin('f.firmShop WITH f.id = s.shopFirmId', 's')
->where('u.id = :user_id')
->setParameter('user_id', $user_id)
->getQuery();
at the moment running the code results in an error
[Syntax Error] line 0, col 57: Error: Expected end of string, got 'u'
What would be best practice for my issue?
Help would be much appreciated,
Thank you!
UPDATE
tried:
$query = $em->createQueryBuilder()
->select('s.id')
->from('App:User', 'u')
->leftJoin('u.userFirm WITH f.firmUser = u', 'f')
->leftJoin('f.firmShop WITH s.shopFirm = f', 's')
->where('u.id = :user_id')
->setParameter('user_id', $user_id)
->getQuery();
got [Syntax Error] line 0, col 54: Error: Expected end of string, got 'f'
There is no need to use WITH clause if you have defined mapping in your entities, WITH clause is used when you want to join your entities with additional matching criteria
class User
{
/**
* #ORM\YourRelationShipNature(targetEntity="App\Entity\Firm", mappedBy="user")
*/
private $userFirm;
}
class Firm
{
/**
* #ORM\YourRelationShipNature(targetEntity="App\Entity\Shop", mappedBy="firm")
*/
private $firmShop;
}
class Shop
{
//.....
}
And then your could simple use properties to join your entites
$query = $em->createQueryBuilder()
->select('u, f, s')
->from('App:User', 'u')
->leftJoin('u.userFirm', 'f')
->leftJoin('f.firmShop', 's')
->where('u.id = :user_id')
->setParameter('user_id', $user_id)
->getQuery();
I was thinking of something more along the lines of this (assuming the entity names are correct):
$query = $em->createQueryBuilder()
->select('u, f, s')
->from('App:User', 'u')
->leftJoin('App:UserFirm f WITH f.firmUser = u')
->leftJoin('App:FirmShop s WITH s.shopFirm = f')
->where('u.id = :user_id')
->setParameter('user_id', $user_id)
->getQuery();
How can I convert below query to Doctrine:
SELECT restaurants.restaurant_name ,
restaurants.restaurant_id,
j.LASTPRICE
FROM restaurants
LEFT JOIN
(
SELECT f.food_id AS fid,
f.restaurants_restaurant_id AS rid,
Max(f.food_last_price) AS LASTPRICE
FROM foods AS f
LEFT JOIN restaurants AS r
ON r.restaurant_id = f.restaurants_restaurant_id
WHERE f.food_last_price IS NOT NULL
GROUP BY r.restaurant_id) j
ON restaurants.restaurant_id = j.rid
Here is my code:
$qb = $this->_em->createQueryBuilder();
$qb2 = $this->_em->createQueryBuilder();
$getMaxPercentage = $qb2
->select(
'MAX (Food.foodLastPrice) AS LASTPRICE ',
'Food.foodId AS fId',
'Food.restaurantsRestaurantId AS rID'
)
->from($this->entityClass,'Restaurant')
->innerJoin('Restaurant.foods','Food')
->where('Food.foodLastPrice IS NOT NULL')
->groupBy('Restaurant.restaurantId')
->getDQL();
$restaurantList = $qb
->select('Restaurants.restaurantName, Restaurants.restaurantId , j.LASTPRICE')
->from($this->entityClass,'Restaurants')
->leftJoin($getMaxPercentage,'j','WITH','Restaurants.restaurantId = j.rID')
->getQuery()->execute();
dd($restaurantList);
I give an error :
SELECT Restaurants.restaurantName,': Error: Class 'SELECT' is not defined.
I've already known I could set sub queries in main query, Although in this case I does not want to use sub query in Where expression. Any suggestion for using select in LeftJoin in doctrine?
EDITED : I've tried to use DQL in my query:
$query = $this->_em->createQuery(
'
SELECT Restaurants.restaurantName , Restaurants.restaurantId
FROM App\\Restaurant AS Restaurants
LEFT JOIN (
SELECT f.foodId AS fid,
f.restaurantsRestaurantId AS rid,
Max(f.foodLastPrice) AS LASTPRICE
FROM App\\Food AS f
LEFT JOIN App\\Restaurant AS r
WITH r.restaurantId = f.restaurantsRestaurantId
GROUP BY r.restaurantId) AS J
ON Restaurants.restaurantId = j.rid
');
But I gave an another error :
[Semantical Error] Error: Class '(' is not defined.
Is it possible to use select in left join in Doctrine?
EDITED 2 : I read a similar question and I've decided to write in another way :
$qb = $this->_em->createQueryBuilder();
$qb2 = $this->_em->createQueryBuilder();
$subSelect = $qb2
->select(
array(
'Food.foodLastPrice AS LASTPRICE ',
'Food.foodId AS fId',
'Food.restaurantsRestaurantId AS rId')
)
->from($this->entityClass,'Restaurant')
->innerJoin('Restaurant.foods','Food')
->where('Food.foodLastPrice IS NOT NULL')
->groupBy('Restaurant.restaurantId')
->getQuery()->getSQL();
$restaurantList =
$qb->select(
'Restaurant1'
)
->from($this->entityClass, 'Restaurant1')
->leftJoin('Restaurant1',sprintf('(%s)',$subSelect),'internalQuery','Restaurant1.restaurantId = internalQuery.rId')
->getQuery()->getSQL();
dd($restaurantList);
Again, I got an error:
near 'Restaurant1 (SELECT': Error: Class 'Restaurant1' is not defined.
What you're trying to do is impossible :
https://github.com/doctrine/doctrine2/issues/3542 (november 2013, but doctrine concept didn't change since and doctrinebot closed this on 7 Dec 2015)
DQL is about querying objects. Supporting subselects in the FROM
clause means that the DQL parser is not able to build the result set
mapping anymore (as the fields returned by the subquery may not match
the object anymore). This is why it cannot be supported (supporting it
only for the case you run the query without the hydration is a no-go
IMO as it would mean that the query parsing needs to be dependant of
the execution mode).
In your case, the best solution is probably to run a SQL query instead
(as you are getting a scalar, you don't need the ORM hydration anyway)
You can find workarounds like raw sql, or rethinking your query.
I'm using Doctrine's querybuilder in Symfony2 to create a query to fetch entities.
I'm trying to get this result in MySQL :
SELECT u0_.id AS id0
FROM user u0_
LEFT JOIN rva_victims r3_ ON u0_.id = r3_.user_id
INNER JOIN rva r1_ ON r1_.id = r3_.rva_id or u0_.id = r1_.declarant_id
I've tried both ON and WITH conditionType in $qb->join(), but nothing work.
Any ideas to solve my problem?
The solution should be pretty straightforward. In your case it should look like this, assuming you're in the repository class:
$this
->createQueryBuilder('u')
->leftJoin(Victims::class, 'v', Query\Expr\Join::WITH, 'v.user = u.id')
->join(Rva::class, 'r', Query\Expr\Join::WITH, 'r.id = v.rva OR u.id = r.declarant');
This should work fine, I am just assuming the class names right now. Please also take in account that all the conditions are done on class attribute names (DQL), not column names.
You can do this by creating a query builder in entity repository
$qb = $this->createQueryBuilder('u')
->leftJoin('yourbundle:Entityname', 'ye', 'WITH', 'u0_.id = r3_.user_id')
->innerJoin('yourbuncle:entityname', 'yen', 'WITH', 'r1_.id = r3_.rva_id', 'OR', 'u0_.id = r1_.declarant_id');
iam trying to join multiple tables in my bundle using DQL and
Error:
[Syntax Error] line 0, col 610: Error: Expected =, <, <=, <>, >, >=, !=, got 'CarparkFueltext'
Entity:
https://gist.github.com/anonymous/9fc7bfe89bb54427f89c
Code:
https://gist.github.com/anonymous/63680019a3f260733dca
I have also tried with createQueryBuilder() method
Code:
https://gist.github.com/anonymous/92012697fc99fcf02da5
ERROR:
[Syntax Error] line 0, col 423: Error: Expected Literal, got 'JOIN'
However if i remove either of the join statements
JOIN MyBundle:SpareParts\CarparkAgestext CarparkAgestext
OR
JOIN MyBundle:SpareParts\CarFueltext CarFueltext
I am getting the data.
The error seems to be that I cannt join multiple tables and i need to join atleast 5 tables to it. Any Idea how can i acheive it.
Join syntax is here.
General example:
...
->select(['e1'])
->from('AcmeDemoBundle:Entity1', 'e1')
->innerJoin('AcmeDemoBundle:Entity2', 'e2', 'WITH', 'e2.e1 = e1')
->innerJoin('AcmeDemoBundle:Entity3', 'e3', 'WITH', 'e3.e2 = e2')
...
You can join multiple tables, but you need to use the right association of MyBundle:SpareParts\Carparktype.
You should use a query like the following one:
$query = $this->getEntityManager()->createQueryBuilder()
->select($fields)
->from('MyBundle:SpareParts\Carparktype Carparktype')
->innerJoin('Carparktype.agesText CarparkAgestext')
->where('Carparktype.makename =:makename')
->andWhere('CarparkAgestext.id =:agesid')
->setParameter('makename',$makename)
->setParameter('agesid',$param)
->getQuery()
->getResult();
As you see you will build a JOIN statement starting from a single property of SpareParts\Carparktype, which will be mapped as an association (a foreign key) for SpareParts\CarparkAgestext.
Maybe you're trying to JOIN two tables with no relationship defined. If that's the case you can JOIN them using WITH
FROM FooBundle:Entity1 e1 JOIN FooBundle:Entity2 e2 WITH e2.e1_id = e1.id
In Symfony2, I have a many:many relationship between users and roles.
I am trying to get a list of all the users which are not linked to the ROLE_SUPER_ADMIN role.
Before migrating to Symfony2/Doctrine, I had achieved this with a simple NOT IN sql query, but for the life of me I can't achieve the same effect with doctrine.
Here is what I am trying:
$em = $this->getDoctrine()->getManager();
$qb = $em->createQueryBuilder();
$qb2 = $qb;
$dql = $qb->select('sa.id')
->from('AcmeAdminBundle:User', 'sa')
->leftJoin('sa.roles', 'r')
->andWhere('r.role = :role')
->getDQL();
$result = $qb2->select('u')
->from('AcmeAdminBundle:User', 'u')
->where($qb2->expr()->notIn('u.id', $dql))
->setParameter('role', 'ROLE_SUPER_ADMIN')
$users = $result->getQuery()->getResult();
But this is the error:
[Semantical Error] line 0, col 140 near 'sa LEFT JOIN':
Error: 'sa' is already defined.
And this is the output:
SELECT u
FROM AcmeAdminBundle:User sa
LEFT JOIN sa.roles r, AcmeAdminBundle:User u
WHERE u.id NOT IN (
SELECT sa.id
FROM AcmeAdminBundle:User sa
LEFT JOIN sa.roles r
WHERE r.role = :role
)
No idea why it is outputting like that as it should not be performing LEFT JOIN two times, my suspicion is that it has something to do with having two QueryBuilder instances, but could be something else entirely.
You need the MEMBER OF or in your case NOT MEMBER OF option.
$qb->select('sa.id')
->from('AcmeAdminBundle:User', 'sa')
->where(":Role NOT MEMBER OF sa.roles")
->setParameter("Role", <<ROLE_ID_OR_ROLE_ENTITY>>);
I didn't test this code, but it should give you some idea.
