I try to do this query using doctrine query builder
$idAccount = $params['idAccount'];
$qb = $this->_em->createQueryBuilder()->select('t,tt')
->from($this->_entityName, 'sr')
->innerJoin('sr.account', 'a')
->innerJoin('sr.product', 'p')
->leftJoin('p.title', 't')
->leftJoin('p.set', 's')
->leftJoin('s.idTitle', 'tt');
$qb->where($qb->expr()->eq('a.idAccount',$idAccount));
end have this error:
E_WARNING
class_parents() [function.class-parents]: object or string expected
D:\Doctrine\ORM\Mapping\ClassMetadataFactory.php : 224
but when I fetch select('sr,a,p,s,t,tt') with this criteria all works fine. and when i use HYDRATE_ARRAY hydration all works fine too. But I need only t and tt fields, is there any way to do this??
For object hydration you have to fetch the element set in FROM clause currently. There might even be an open bug/enhancement report for this.

I am new in Symfony, and I have a problem with an existing application I maintain.
In one of the repositories, there's is a method, that selecting the failed transactions, and the related payment.
Now, they have asked me, to allow filter the transactions, based on the total amount of failed transactions which could be either 1 failed transaction or 2.
What I am trying to do in the query builder, is something like that:
$this
->createQueryBuilder('t')
->join('t.payment', 'p')
->leftJoin( Transaction::class, 'tr', Query\Exprt\Join::WITH, 'p.id = tr.payment')
->groupBy('tr.id');
Until that point everything is fine. The query is executed normally, and I can see the transactions I need.
Now the problem is that I cannot use the following statement:
$this
->createQueryBuilder('t')
// This is the column I need to insert
->addSelect('COUNT(tr.id) AS TotalRecords')
->join('t.payment', 'p')
->leftJoin( Transaction::class, 'tr', Query\Exprt\Join::WITH, 'p.id = tr.payment')
->groupBy('tr.id');
Because the output looks like that:
array:1 [▼
0 => array:2 [▼
0 => Transaction {#1221 ▶}
"TotalRecords" => "1" <- This is the total transactions number I need
]
]
Instead of the output above, I need to have the TotalRecords inside the Transaction Object.
So, Is there a way to achieve that with the query builder? Do you think I do something wrong?
you can just loop over your result set and set TotalRecords on all Transaction objects... and return an array of Transactions, as you probably have hoped. The overhead is minimal but the standard doctrine hydration isn't smart enough
// the following is your query:
$qb = $this
->createQueryBuilder('t')
->addSelect('COUNT(tr.id) AS TotalRecords')
->join('t.payment', 'p')
->leftJoin( Transaction::class, 'tr', Query\Exprt\Join::WITH, 'p.id = tr.payment')
->groupBy('tr.id');
// fetch the results, and instead of straight returning them, "merge"
$results = $qb->getQuery()->getResult();
$return = [];
foreach($result as $row) {
$row[0]->totalCount = $row['TotalCount'];
$return[] = $row[0];
}
return $return; // <-- now an array of Transaction
you also could just not use addSelect but instead having and just use the number of transactions you want to filter by, as a parameter (unless the filtering is done later, in which case that approach won't work)
I saw the begining of an answer in a post about Zend : Join subquery with doctrine 2 DBAL
Unfortunately I can't manage it to work. I tried aimfeld soltuion like that:
$qbaudio = $em->createQueryBuilder();
$subSelect = $qbaudio->select ('a.id_support id_support','sum(a.duration) dureeTotale','count(a) nbAudio')
->from('MyBundle:AudioObject','a')
->groupBy('a.id_support')
->where('a.type = :audio_type')
->getQuery();
$qb = $em->createQueryBuilder();
$qb->select('sp.ref1','sp.title1','count(i) nbImage','sp.nbSupportSaisi','sum(a.duration) dureeTotale','count(a) nbAudio','a.sampling')
->from('MyBundle:Storage', 'st')
->leftJoin('p.sides','si')
->leftJoin('si.support','sp')
->leftJoin('sp.images','i')
->leftJoin('sp.audioObjects', sprintf('(%s)',$subSelect->getDQL()), 'a', 'ON sp.id = a.id_support')
->groupBy('sp.id')
->setParameter('audio_type', 'MP3')
Unfortunately I got this message :
Error: Expected end of string, got 'SELECT'
If it's possible with ZEnd, Why not with Symfony?
Any idea?
Thanks
Use SQL instead of DQL:
$subSelect->getSQL()
Before I begin, I believe I have tried everything from this previous post: How to use WHERE IN with Doctrine 2
So I have a Silex application connected to a MySQL DB using Doctrine via composer (doctrine/dbal 2.2.*)
The query builder I am trying to run is this:
$qb = $this->db->createQueryBuilder();
$stmt = $qb->select('DAY(datefield1) x, COUNT(*) value')
->from('table1', 's')
->join('s', 'table2', 't', 't.key=s.key')
->where('MONTH(datefield1) = :billMonth')
->andWhere('YEAR(datefield1) = :billYear')
->andWhere('t.key IN (:keylist)')
->groupBy('x')
->orderBy('x', 'asc')
->setParameter(':billMonth', $month)
->setParameter(':billYear', $year)
->setParameter(':keylist', implode(",", $keylist))
->execute();
return $stmt->fetchAll(\PDO::FETCH_ASSOC);
The parameters are (month=8)(year=2014)(keylist=array(1,2,3,4))
The query does not fail but it curiously doesn't contain all the data that it should.
I have tried ->setParameter(':keylist', $keylist) to use the raw array, and this didn't work.
I have tried this kind of syntax too:
$qb->add('where', $qb->expr()->in('r.winner', array('?1')));
However that threw up an error because the in method wasn't available in expression builder class.
Please will someone cast an eye over this and save me from having to hardcode my SQL?
OK seeing as this old thread has seen some action since I last looked I wanted to confirm that the issue is long resolved - a third parameter in setParameter allows you to inform Doctrine how to handle the array:
$qb = $this->db->createQueryBuilder();
$stmt = $qb
->select('*')
->from(self::DB_TABLE, 'x')
->where('x.service IN (:services)')
->orderBy('x.session_end', 'DESC')
->addOrderBy('x.direction', 'DESC')
->setParameter(':services', $services, \Doctrine\DBAL\Connection::PARAM_STR_ARRAY)
->setFirstResult($offset)
->setMaxResults($count)
->execute();
$result = $stmt->fetchAll(\PDO::FETCH_ASSOC);
DB placeholders/parameters are for single values. You're passing in a monolithic string 1,2,3,4 due to calling implode() on the array. Given:
WHERE t.key IN (:keylist)
then this query will be executed as the equivalent of
WHERE t.key IN ('1,2,3,4')
^-------^---note the quotes
Since it's a string, and only one single string in the IN clause, it's the functional equivalent of
WHERE t.key = '1,2,3,4'
and not the
WHERE (t.key = 1 OR t.key = 2 OR ....)
you want it to be. Either set up multiple parameters, one for each value in your array, or embed your string in the query directly
->andWhere('t.key IN (' . implode(',', $keylist) . ')')
which of course opens you up to sql injection attack vulnerabilities.
If you build the sql query yourself you can use DBAL's PARAM_INT_ARRAY type:
use Doctrine\DBAL\Connection as DB;
$db->executeQuery('SELECT DAY(datefield1) x, COUNT(*) value
FROM table1 s
JOIN table2 t ON t.key=s.key
WHERE MONTH(datefield1) = :billMonth
AND YEAR(datefield1) = :billYear
AND t.key IN (:keylist)
GROUP BY x
ORDER BY x ASC',
array(':billMonth' => $month, ':billYear' => $year, ':keylist' => $keylist),
array(':billMonth' => \PDO::PARAM_INT, ':billYear' => \PDO::PARAM_INT, ':keylist' => DB::PARAM_INT_ARRAY
)->fetchAll(\PDO::FETCH_ASSOC);
Correct way to handle such IN clause is as simple as it can be:
$qb = $this->db->createQueryBuilder();
$stmt = $qb->(...)
->andWhere('t.key IN (:keylist)')
->setParameter(':keylist', $keylist)
->getQuery()
->getArrayResult();
I have used this dozen times and it works - doctrine is smart enough to handle your $keylist being array.
Other thing is that I don't know why you're using fetchAll method which is reduntant here - execute() is just enough. Maybe this is a root of your problem.
My suggestion: try to fire action in dev mode (app_dev.php) and check your app/logs/dev.log - you will find all sql queries performed. Verify that database returns data which you are expecting from Doctrine.
->add('where', $qb->expr()->andX(
$qb->expr()->in('r.winner', ':winner')
))
->setParameters(array(
"winner" => $winners,
"billMonth", $month,
// add all params here
));
You should use the in expression via the querybuilder like below, and change how you set the parameter:
->andWhere($qb->expr()->in('t.key', ':keylist'))
The complete code:
$qb = $this->db->createQueryBuilder();
$stmt = $qb->select('DAY(datefield1) x, COUNT(*) value')
->from('table1', 's')
->join('s', 'table2', 't', 't.key=s.key')
->where('MONTH(datefield1) = :billMonth')
->andWhere('YEAR(datefield1) = :billYear')
->andWhere('t.key')
->andWhere($qb->expr()->in('t.key', ':keylist'))
->groupBy('x')
->orderBy('x', 'asc')
->setParameter(':billMonth', $month)
->setParameter(':billYear', $year)
->setParameter(':keylist', $keylist)
->execute();
return $stmt->fetchAll(\PDO::FETCH_ASSOC);
I have an SQL query that works fine and I'm trying to convert into fluent::
SELECT DISTINCT tags.tag
FROM tags, items
WHERE tags.taggable_type = 'Item'
AND items.item_list_id = '1'
UNION
SELECT DISTINCT tags.tag
FROM tags, itemlists
WHERE tags.taggable_type = 'ItemList'
AND itemlists.id = '1'
This is what I have so far in fluent, it all seems right as far as I can tell from the docs and the individual queries both work on their own, it's just when I UNION them it throws an error:
$itemTags = Tag::join('items', 'items.id', '=', 'tags.taggable_id')
->select('tags.tag')
->distinct()
->where('tags.taggable_type', '=', 'Item')
->where('items.item_list_id', '=', $itemList->id);
$itemListTags = Tag::join('itemlists', 'itemlists.id', '=', 'tags.taggable_id')
->select('tags.tag')
->distinct()
->where('tags.taggable_type', '=', 'ItemList')
->where('itemlists.id', '=', $itemList->id);
// the var_dump below shows the expected results for the individual queries
// var_dump($itemTags->lists('tag'), $itemListTags->lists('tag')); exit;
return $itemTags
->union($itemListTags)
->get();
I get the following error when I run it (I've also swapped from Ardent back to Eloquent on the model in case that made a difference - it doesn't):
Argument 1 passed to Illuminate\Database\Query\Builder::mergeBindings() must be an instance of Illuminate\Database\Query\Builder, instance of LaravelBook\Ardent\Builder given, called in path/to/root\vendor\laravel\framework\src\Illuminate\Database\Query\Builder.php on line 898 and defined
Looks like your models are using Ardent, not Eloquent:
...instance of LaravelBook\Ardent\Builder given, ...
And probably this might be a problem on Ardent, not Laravel.
Open an issue here: https://github.com/laravelbook/ardent.
EDIT:
Try to change use QueryBuilder instead of Eloquent:
Use this for QueryBuilder:
DB::table('tags')->
Instead of the Eloquent way:
Tag::
I know you mentioned wanting to use the query builder, but for complex queries that the builder might throw fits on, you can directly access the PDO object:
$pdo = DB::connection()->getPdo();
I'm using Doctrine 1.2 and Symfony 1.4.
In my action, I have two different query that return different result set. Somehow the second query seem to change the result (or the reference?) of the first one and I don't have any clue why..
Here is an example:
$this->categories = Doctrine_Query::create()
->from('Categorie AS c')
->innerJoin('c.Activite AS a')
->where('a.archive = ?', false)
->execute();
print_r($this->categories->toArray()); // Return $this->categories results, normal behavior.
$this->evil_query = Doctrine_Query::create()
->from('Categorie AS c')
->innerJoin('c.Activite AS a')
->where('a.archive = ?', true)
->execute();
print_r($this->categories->toArray()); // Should be the same as before, but it return $this->evil_query results instead!
Why Doctrine behave this way ? It's totally driving me crazy. Thanks!
To make it simple it seem like the Query 2 are hijacking the Query 1 result.
Use something like this between queries ($em - entity manager):
$em->clear(); // Detaches all objects from Doctrine!
http://docs.doctrine-project.org/en/2.0.x/reference/batch-processing.html
In the API docs for the toArray() method in Doctrine_Collection it says:
Mimics the result of a $query->execute(array(), Doctrine_Core::HYDRATE_ARRAY);
I suspect to answer this question to your satisfaction you're going to have to go through the source code.
This seems like it has to be an issue of $this->categories and $this->evil_query pointing to the same place. What are the results of $this->evil_query === $this->categories and $this->evil_query == $this->categories?
Hubert, have you tried storing the query into a separate variable and then calling the execute() method on it?
I mean something like:
$good_query = Doctrine_Query::create()
->from('...')
->innerJoin('...')
->where('...', false)
;
$evil_query = Doctrine_Query::create()
->from('...')
->innerJoin('...')
->where('...', true)
;
$this->categories = $good_query->execute();
$this->evil_query = $evil_query->execute();
It seems like both attributes (categories and evil_query) are pointing at the same object.
Erm, after both queries you print_r the result of the first query - change the last line to print_r($this->evil_query->toArray()); to see the difference :)
