I have 2 entities (ProductX and ProductY), herited from Product (inheritance type: JOINED, with Discriminator).
I need to add a condition on ProductX or productY field.
But the query builder doesn't show this entities.
I try :$queryBuilder->leftJoin('App\Entity\ProductX', 'productX', 'WITH', 'o.id = productX.id');
But in this case, the generated DQL is :
LEFT JOIN (
product_x p8_
INNER JOIN product p9_ ON p8_.id = p9_.id
) ON (p0_.id = p9_.id)
instead of :
LEFT JOIN product_x p8_ ON p0_.id = p8_.id
Any idea to do that ?
you can just do something like that I think :
$queryBuilder->leftJoin('App\Entity\ProductX', 'productX');
This will return something you want, other arguments it's generaly use for custom relationship

I hope this can help you

I need help to convert a valid SQL query into createQueryBuilder. The problem I have is I don't know how to LEFT JOIN on a SELECT in the createQueryBuilder.
SELECT username, count(c.user_owner_id) as num_contact, a_g.name as
group_name
FROM `oro_user` as u
INNER JOIN `oro_user_access_group` as u_g on u.id=u_g.user_id
INNER JOIN `oro_access_group` as a_g on u_g.group_id=a_g.id
LEFT JOIN
(SELECT cc.user_owner_id
FROM `orocrm_contact` as cc
INNER JOIN`orocrm_contact_to_contact_grp` as cc_g on cc_g.contact_id=cc.id
INNER JOIN `orocrm_contact_group`
as c_g on cc_g.contact_group_id=c_g.id
WHERE c_g.label='New One' and cc.semester_contacted='2017A')
as c on u.id=c.user_owner_id
WHERE a_g.name='Full-timer' and u.enabled = 1 and u.gender='male'
GROUP BY u.id
ORDER BY num_contact
I have two queries below, I want user to LEFT JOIN the results from contact
$user = $this->em->getRepository('OroUserBundle:User')->createQueryBuilder('u')
->select('u.username')
->innerJoin('u.groups','g')
->andWhere('g.name = :group')
->setParameter('group', 'Full-timer')
->getQuery();
$contacts = $this->em->getRepository('OroContactBundle:Contact')->createQueryBuilder('c')
->select('c')
->innerJoin('c.groups','g')
->andWhere('g.label = :group')
->andWhere('c.semester_contacted = :sem')
->setParameter('group', 'New One')
->setParameter('sem', '2017A')
->setMaxResults(1)
->getQuery();
This is a pretty complex queries and since the ORM QueryBuilder works closer to your entities than the database I'm not sure if you can just "dump" the DQL into a ->join(). The good news with the DBAL QueryBuilder that works:
$dbalQueryBuilder
->from('user_table as u')
...
->join('u', '('.$otherDbalQueryBuilder->getSQL().')', 'c')
This is from memory so it might be a little different, but something like that.
With that you can get all the fields you require, but you won't get any entities. Luckily Doctrine provides ways to build entities from Native SQL using ResultSetMapping.
$userWithContacts = $entityManager->createNativeQuery(
$dbalQueryBuilder->getSQL(),
$yourResultSetMapping
);
I know this is will require more code and is probably not as nice as just using the ORM QueryBuilder, but I find it oftentimes to be the best way to deal with existing queries that need to be ported to ORM somehow.
I have the following Entities. First and foremost: the design derived from a legacy DB and it has been semplified here for clarity shake.
What I would like to do is selecting all the widgets along with their varsSelection populated (in this very moment Widget only contains PhyVarSelection instances so we can focus on them) which should have teir phyVar hydrated. Phyvar must not be populated with its ewCfgVar property.
I'm trying to do it by using DQL. I succeeded to select all the widgets and their relative varsSelection, but I'm not able to populate their relative phyVar. Is that possible? Here is the DQL I'm using:
$sql = <<<EOS
SELECT wid, partial phyvarsel.{id, phyVar, start}
FROM Belka\\TsBundle\\Entity\\Widget wid
LEFT JOIN Belka\\TsBundle\\Entity\\PhyVarSelection phyvarsel WITH wid.id = phyvarsel.widget
LEFT JOIN Belka\\TsBundle\\Entity\\PhyVar phyvar WITH phyvarsel.phyVar = phyvar.id
EOS;
$query = $this->getEntityManager()->createQuery($sql);
If I dump the result, Widget and varsSelection are correctly populated, but PhyVarSelection::phyVar is set to NULL.
The query DQL it generates is actually correct, and if I query it I get all the PhyVar's properties:
die(var_dump($query->getSQL()));
It generates:
SELECT a0_.id AS id0, a0_.title AS title1, a0_."order" AS order2, a0_.span_cols AS span_cols3, a0_.description AS description4, a1_.id AS id5, a1_.start AS start6, a2_.id AS id7, a0_.part_of_section AS part_of_section8, a1_.vartype AS vartype9, a1_.part_of_widget AS part_of_widget10, a1_.phy_var_sel AS phy_var_sel11, a2_.vartype AS vartype12, a2_.part_of_phy_meter AS part_of_phy_meter13, a2_.varname AS varname14, a2_.id_device AS id_device15 FROM app_t.widget a0_ LEFT JOIN app_t.var_selection a1_ ON (a0_.id = a1_.part_of_widget) AND a1_.vartype IN ('phy') LEFT JOIN app_t.variable a2_ ON (a1_.phy_var_sel = a2_.id) AND a2_.vartype IN ('phy');
I don't paste here the Entities' code but if you need it let me know with a comment below and I will update the question.
Update
I've also tried the following:
$sql2 = <<<EOS
SELECT phyvarsel, phyvar
FROM Belka\\TsBundle\\Entity\\PhyVarSelection phyvarsel
LEFT JOIN Belka\\TsBundle\\Entity\\PhyVar phyvar
WHERE phyvarsel.id = :phyvarselid
EOS;
$query2 = $this->getEntityManager()->createQuery($sql2);
$query2->setParameter('phyvarselid', '0');
$query2->setHint(Query::HINT_FORCE_PARTIAL_LOAD, true);
$varSel = $query2->getResult();
again, in this case I get PhyVarSelection but its attribute phyVar is still set to NULL.
Here is the SQL equivalent of what I expect to get from Doctrine:
SELECT c.* FROM comments c
LEFT JOIN articles a
ON a.id = c.articles_id OR a.translation = c.articles_id
WHERE c.published = 1 AND c.language = a.language
The problem is that I cannot make Doctrine to generate the JOIN operation with OR as it is supposed to be. If we execute query from the following QueryBuilder object:
$qb->select('c')
->from('Project:Comment', 'c')
->leftJoin('c.article', 'a', 'WITH', 'a = c.article OR a.translation = c.article')
->where('c.published = true AND c.language = a.language');
we receive the following SQL statement:
SELECT
...
FROM comments c0_
LEFT JOIN articles a0_ ON c0_.articles_id = a0_.id
AND (
a0_.id = c0_.articles_id OR
a0_.translation = c0_.profiles_id
)
WHERE c0_.published = 1 AND c0_.language = a0_.language
which is obviously not the same as the initial query, as WITH operator seems to add additional conditions to the basic one instead of replacing the whole condition.
Is there any way to force Doctrine to output exactly what I need? I know that I may use native SQL but I doubt that it will be as convenient as QueryBuilder. Maybe there is a way to extend Doctrine with normal JOIN ON implementation instead of this odd JOIN WITH?
Doctrine doesn't implement this because it is (as far as I understand at least) not considered optimized enough for SQL.
See this SO post for precisions.
What you intend to do could appearantly be done using Union and other types of Join.
These are my tables:
Table Gift:
-id
-price
...
Table Couple:
-id
-name
...
table registry: //provide a many-many relation between gifts and couples
-id
-coupleId
-giftId
table purchase:
-amount
-registryId
I already wrote a sql query to get all the gift info for a specific couple
$qb = $this->createQueryBuilder('g') //gift
->from('\BBB\GiftBundle\Entity\Registry', 'reg')
->select('g.id , g.price')
->where('reg.gift = g.id')
->andWhere('reg.couple = :coupleID')
->orderBy('reg.id','DESC')
->setParameter('coupleID', $coupleID);
OR
SELECT g.id , g.price,
FROM gift g, registry reg
WHERE reg.gift_id = g.id AND reg.couple_id = 1
I also want to get the total amount that for the gifts that have been bought (if any)
EX. SUM(purchase.amount) as totalContribute
I have tried:
$qb = $this->createQueryBuilder('g')
->from('\BBB\GiftBundle\Entity\Purchase', 'p')
->from('\BBB\GiftBundle\Entity\Registry', 'reg')
->select('g.id , g.price')
->addSelect('SUM(p.amount) as totalContribute')
->leftJoin('p','pp', 'ON','reg.id = pp.registry')
->where('reg.gift = g.id')
->andWhere('reg.couple = :coupleID')
->orderBy('reg.id','DESC')
->setParameter('coupleID', $coupleID);
but it gives me the following error:
[Semantical Error] line 0, col 145 near 'pp ON reg.id': Error: Identification Variable p used in join path expression but was not defined before.
First of all, you should define join condition in your SQL statements after joins, not in WHERE clause. The reason is that it's really not efficient. So the query shoul look like:
SELECT g.id , g.price,
FROM gift g JOIN registry reg ON reg.gift_id = g.id
WHERE reg.couple_id = 1
But about your Doctrine query, You get error because you're defining joins in wrong way. Your query should more like:
$qb = $this->createQueryBuilder('g') // You don't have put "from" beacuse I assume you put this into GiftRepository and then Doctrine knows that should be \BBB\GiftBundle\Entity\Gift
->select('g.id , g.price')
->addSelect('SUM(p.amount) as totalContribute')
->join('g.purchase','p') // pay attention for this line: you specify relation basing on entity property - I assume that is "$purchase" for this example
->leftJoin('p.registry', 'reg') // here you join with \BBB\GiftBundle\Entity\Purchase
->where('reg.couple = :coupleID')
->orderBy('reg.id','DESC')
->setParameter('coupleID', $coupleID);
Please treat this as pseudocode - I didn't check it works but it should like more like this.
One more thing - if your repository method returns object(s) of X entity you should put this method to XRepository.
Okay, so i've got a query that i've researched and researched how to get this to work and for the life of me i cant!... perhaps i'm just doing this incorrectly and the minimal information ive found..
I've got a table named timeclock setup.. which has a field: noteBy_id in it which is an id to the user the record belongs to...
What I need to do now, is for the management side of things in the system.. I anticipate more than 1 company using this timeclock system, and as such I need to filter the results based on the company id.. In the user table, i have a field named parentcompany_id
So, lets see if I can express in words what I need to do..
I need to Select * from timeclock and left join user.parentcompany_id where timeclock.daydate < :start and where u.parentcompany = :pid
where start is: `date('Y-m-d 00:00:00');
I've setup this query:
$em = $this->getDoctrine()->getEntityManager();
$start = date('Y-m-d 00:00:00');
$qb = $em->getRepository('EcsCrmBundle:TimeClock');
$qb = $qb->createQueryBuilder('t');
$query = $qb->select('t, u.parentcompany_id')
->from('timeclock', 't')
->leftJoin('Ecs\AgentManagerBundle\Entity\User', 'u', 'ON' 'u.id = t.noteBy_id AND u.parentcompany_id = :pid')
->where('t.daydate < :start')
->andWhere("t.noteBy_id != ''")
->setParameter('start', $start)
->setParameter('pid', $user->getParentcompany())
->getQuery();
$entities = $query->getArrayResult();
I've looked and looked and can't find a solution to the error that I get which is:
An exception has been thrown during the rendering of a template ("[Semantical Error] line 0, col 112 near 'u ON u.id = t.noteBy_id': Error: Identification Variable Ecs\AgentManagerBundle\Entity\User used in join path expression but was not defined before.") in EcsCrmBundle:TimeClock:manager.html.twig at line 5.
and the query that gets output is:
SELECT t, u.parentcompany_id FROM Ecs\CrmBundle\Entity\TimeClock t LEFT JOIN Ecs\AgentManagerBundle\Entity\User u ON u.id = t.noteBy_id AND u.parentcompany_id = :pid, timeclock t LEFT JOIN Ecs\AgentManagerBundle\Entity\User u ON u.id = t.noteBy_id AND u.parentcompany_id = :pid WHERE t.daydate < :start AND t.noteBy_id != ''
which under normal circumstances would work perfectly... but in this, it just doesn't... Any ideas?
I've recently had to do it like this.. I'm guessing in this that your noteBy is a ManyToOne in the user table and you are wanting to have it filter the results by the company of the admin that is currently logged into your system..
So, adapting a join I had to write myself for such a task is easy enough. I personally like to use the QueryBuilder so this will be done in query builder..
Your first mistake in your query is the ->from('timeclock', 't') line. Because you have previously created your object with $qb = $em->getRepository('EcsCrmBundle:TimeClock'); $qb = $qb->createQueryBuilder('t'); you don't need the from in the query builder, as it will be generated for you.
The next issue, is the leftJoin and I'll explain why when I've shown you a working version.
And the last issue, preventing this from working how you want it - is a missing andWhere clause. So, lets take a look at a working query.
$query = $qb->select('t, u')
->leftJoin('t.noteBy', 'u', 'WITH', 'u.id = t.noteBy')
->where('t.daydate < :start')
->andWhere('u.parentcompany = :pid')
->setParameter('start', $start)
->setParameter('pid', $user->getParentcompany())
->getQuery();
So because we've already created the object by using $qb = $qb->createQueryBuilder('t') we just select t and u
For the join, we're joining the timeclock table by the noteBy column, which is the user id from the user table. So, the first argument being the "from" alias. So, since we've aliased the timeclock table with t we use t.noteBy. The next argument in the leftjoin is the alias of the 2nd table, which is u in this case but can be anything.. The third argument for a leftJoin anyway - is the way you join it.. either a WITH or ON will work here. and the 4th argument, is the match you wish it to have.. in this case u.id must equal t.noteBy
You will see that I got rid of one of the andWhere, I did this because with the properly structured query you shouldn't need it. I did however add in the andWhere for the u.parentcompany since that is afterall what you are looking to filter by you should have it in a WHERE instead of as a match in the join itself.
The documentation is very limited in this, and it took me a while to figure it all out as well.. You, undoubtedly - like me, came to using doctrine from writing your queries by hand. And So since you seem to be just starting with Symfony (i am myself as well about 2 months in now), you're still in the hand-coding mindset. But with further time, you'll start understanding the DQL way of life. Try this query out and see what happens.
Ok, first you would need to relate entity Timeclock to Company. Whenever you want to join two entities in Doctrine they need to be related by some attribute (that is, table column).
I don't see any need for User entity in this query as all info is available through Company entity and you are not filtering down results based on any user properties.
You desired query should look something like this (more or less). I took liberty and ditched _id suffixes from entity attributes as they tend to cloud what is really going on. ;)
$query = $this->getEntityManager()->createQuery("SELECT t, c.id FROM EcsCrmBundle:TimeClock t JOIN t.company c WHERE c.id = :pid AND t.daydate < :start AND t.noteBy != ''");
$query->setParameter('start', $start);
$query->setParameter('pid', $user->getParentcompany());
return $query->getArrayResult();
Also, I did inner-join (JOIN) as I think there could not be timeclock without it's company but feel free to change that to LEFT JOIN if that suits you better.
Is this what you were trying to achieve?
