I'm trying to make a quite complex query with the QueryBuilder of Doctrine 2.
I would like to SELECT a SUM of elements FROM the result of a subquery.
Here is what I try for now, trying to guess the use of all() method (see : http://doctrine-orm.readthedocs.org/en/latest/reference/query-builder.html)
$qb = $this->createQueryBuilder('stuff');
$qb->select('SUM(perf_final.perf_ratio) AS stuff_perf, date AS date')
->from($qb->expr()->all($qb2->getDql()), 'perf_final')
->groupBy('YEAR(perf_final.date)')
->addGroupBy('MONTH(perf_final.date)');
But, Symfony tells me that ALL is an undefined method...
Any ideas of what could be a good practice to do what I need?
Thx,

I am using multiple condition in join clause in laravel5 and there is one condition that is passed as a raw condition. How to pass it ?
I am getting this error
Call to undefined method Illuminate\Database\Query\JoinClause::whereRaw()
Code is
->leftjoin('log_simple_calory as LC',
function($join)use($tz_lccreated_date,$dateRange){
$join->on('LC.user_id_fk','=','UA.user_id_fk');
$join->on('LC.is_active','=',DB::raw('1'))
->whereRaw('date('.$tz_lccreated_date.')'. $dateRange);
})
The whereRaw should be outside the JoinClause :
->leftjoin('log_simple_calory as LC',
function($join)use($tz_lccreated_date,$dateRange){
$join->on('LC.user_id_fk','=','UA.user_id_fk');
$join->on('LC.is_active','=',DB::raw('1'))
})->whereRaw('date('.$tz_lccreated_date.')'. $dateRange);
If you are using laravel 5 and above, this site is very useful,
for writing raw queries and stuff
https://laravel.com/docs/5.4/queries
I have this query in laravel 5.2
$obj_custom_stdy_data = QstCustomStudyData::where('student_id', $this->data_user['student_id'])
->select($list_id . ' as list_id ', 'chapter_id', 'subject_id', 'subject_code_id')
->get()
->toArray();
Well I have a fixed value $list_id got from top code. Actually I want to add new field during query selection as list_id. However I got error for such that method.
When I tried in mysql IDE for example:
SELECT (1+2) as total, c.* FROM users
Then the result is no wrong at all.
Is that anyway to write in query builder for laravel instead of raw style?
You can take the use of DB::raw() method of QueryBuilder like this:
->select(DB::raw('(1+2) as total'));
See more about Query Builder's Raw Expressions
Hope this helps!
I have following code in my Repository
// ProductBundle/Repository/ProductRepository.php
$qb->where($qb->expr()->eq('afp.id', 15));
$qb->andWhere($qb->expr()->eq('afp.id', 14));
return $qb
->select('a', 'afp')
->leftJoin('a.productFields', 'afp')
->getQuery()
->getResult();
But I always get null return, but I want to get products which have both productFields (so orWhere is not good).
You want to use MEMBER OF instead of comparing id. Otherwise, you're looking for a record that has two different id values, which of course isn't possible.
This will do what you want:
$qb->where($qb->expr()->isMemberOf(15, 'a.productFields'));
$qb->andWhere($qb->expr()->isMemberOf(14, 'a.productFields'));
Try something like this (Symfony 5):
$qb->andWhere(':c MEMBER OF a.productFields');
$qb->setParameter('c', 15);
I have two Entities with relation OneToMany, Project and Services. Now i want to remove all the services by project_id.
First attempt:
$qb = $em->createQueryBuilder();
$qb->delete('Services','s');
$qb->andWhere($qb->expr()->eq('s.project_id', ':id'));
$qb->setParameter(':id',$project->getId());
This attempt fails with the Exception Entity Service does not have property project_id. And it's true, that property does not exists, it's only in database table as foreign key.
Second attempt:
$qb = $em->createQueryBuilder();
$qb->delete('Services','s')->innerJoin('s.project','p');
$qb->andWhere($qb->expr()->eq('p.id', ':id'));
$qb->setParameter(':id',$project->getId());
This one generetate a non valid DQL query too.
Any ideas and examples will be welcome.
You're working with DQL, not SQL, so don't reference the IDs in your condition, reference the object instead.
So your first example would be altered to:
$qb = $em->createQueryBuilder();
$qb->delete('Services', 's');
$qb->where('s.project = :project');
$qb->setParameter('project', $project);
If you really can't get project object and you have to handle only with id you can use this.
Citation from doctrine documentation:
There are two possibilities for bulk deletes with Doctrine. You can either issue a single DQL DELETE query or you can iterate over results removing them one at a time. (Below I paste only first solution)
DQL Query
The by far most efficient way for bulk deletes is to use a DQL DELETE query.
Example that worked in my project
$q = $em->createQuery('delete from AcmeMyTestBundle:TemplateBlock tb where tb.template = '.intval($templateId));
$numDeleted = $q->execute();
In entity TemplateBlock I have property called template which is mapped to template_id in db.
But I agree that highly preferred way of doing it is using objects.
I am trying to use Query Builder in Symfony2 to get some records from a database. I run the normal query in SQL and it returns the correct results. The query is
SELECT pg.name, pg.description
FROM pm_patentgroups pg
LEFT JOIN pm_portfolios pp ON pp.id = pg.portfolio_id
I want to use the exact query using Doctorine query builder in Symfony2. What I have tried so far is
$repository = $this->getDoctrine()
->getRepository('MunichInnovationGroupBundle:PmPatentgroups');
$query = $repository->createQueryBuilder('pg')
->from('pm_patentgroups', 'pg')
->leftJoin('pg','pm_portfolios','pp','pp.id = pg.portfolio_id')
->getQuery();
$portfolio_groups = $query->getResult();
but its giving me the following error:
Warning: Missing argument 1 for Doctrine\ORM\EntityRepository::createQueryBuilder()
I am new to Symfony2 and Doctorine. Can you please tell me what is going wrong here?
Thanks
You are missing the alias when using createQueryBuilder. Since you have the repository you can drop the from portion and just use
$query = $repository->createQueryBuilder('pg')
Something like:
$qb = $this->getDoctrine()->createQueryBuilder();
$qb->addSelect('pm_patentgroups');
$qb->addSelect('pm_portfolios');
$qb->from('MunichInnovationGroupBundle:PmPatentgroups','pm_patentgroups');
$qb->leftJoin('pm_patentgroups.pm_portfolios','pm_portfolios');
This assumes you have your two entities properly related.
Lots of examples in the D2 manual. Just keep in mind that query builder works with objects, not sql.
And by the way, your error message comes from the fact that the entity repository (as opposed to the entity manager) requires an alias.
