what can i do if the parameter has no value?
my query:
$query = $this->_em->createQueryBuilder()
->select('u')
->from('Users', 'u')
->where('u.id = ?1')
->andWhere('u.status= ?2')
->setParameter(1, $userid)
->setParameter(2, $status)
->getQuery();
return $query->getResult();
if theres no $status, then it doesnt display anything.
i tried putting a condition before the query to check if its null but what value can i set $status iif theres no status set
The query builder is exactly there for building conditional queries. You could do:
$qb = $this->_em->createQueryBuilder();
$query = $qb->select('u')
->from('Users', 'u')
->where('u.id = ?1')
->setParameter(1, $userid);
if ($status) {
$qb->andWhere('u.status = ?2')
->setParameter(2, $status);
}
return $qb->getQuery()->getResult();
On a side note, it is best practice to use named placeholders e. g. like this:
$qb->andWhere('u.status = :status')
->setParameter('status', $status);
You could write:
->andWhere('(u.status= ?2 or ?2 is null)')

I would like to search for people who are not allocated to a room. I made the following query:
public function findByWithoutRoom()
{
$qb = $this->getEntityManager()->createQueryBuilder();
$qb2 = $this->getEntityManager()->createQueryBuilder();
$qb
->select('p')
->from('MyPeopleBundle:Person', 'p')
->where(
$qb->expr()->exists(
$qb2->select('r')
->from('MyAccommodationBundle:Room', 'r')
->andWhere($qb2->expr()->like('r.currentPeople', ':person'))
->setParameter('person', '%i:'.$person_id.';%')
->getDQL()
)
)
$result = $qb->getQuery()->execute();
return $result;
}
How can I have p.id instead of person_id? Note:The currentPeople property is of type "array" (not "simple_array")
UPDATE:
I also tried the following:
public function finByWithoutRoom()
{
$qb = $this->getEntityManager()->createQueryBuilder();
$qb
->select('p')
->from('MyPeopleBundle:Person', 'p')
->leftJoin('MyAccommodationBundleV2:Room', 'r')
->andWhere($qb->expr()->like('r.currentPeople', '%i:p.id%'));
$result = $qb->getQuery()->execute();
return $result;
}
however this gave me the following error:
[Syntax Error] line 0, col 114: Error: Expected StateFieldPathExpression | string | InputParameter | FunctionsReturningStrings | AggregateExpression, got '%'
You can use directly the alias of the main query, as example:
$qb
->select('p')
->from('MyPeopleBundle:Person', 'p')
->where(
$qb->expr()->isNotNull(
$qb2->select('r')
->from('MyAccommodationBundle:Room', 'r')
->andWhere($qb->expr()->like('r.currentPeople', 'p.id'))
->getDQL()
)
)
->setParameter('from', $from)
->setParameter('to', $to);
I suggest to use an not exists instead of is not null (I think is the same result however). As Example:
$qb->andWhere($qb->expr()->not($qb->expr()->exists($qb2->getDQL())));
Hope this help
A previous question I asked was to do with hydrating a result set when using Doctrine and query builder. My issue was how to return an array and their sub-sets:
This was for a single result set and the answer was quite simple:
$qb = $this->stoneRepository->createQueryBuilder('S');
$query = $qb->addSelect('A','P','I','C')
->leftJoin('S.attribute', 'A')
->leftJoin('A.category', 'C')
->innerJoin('S.product' , 'P')
->innerJoin('S.image' , 'I')
->where('S.id = :sid')
->setParameter('sid', (int) $stone_id)
->getQuery();
$resultArray = $query->getOneOrNullResult(\Doctrine\ORM\Query::HYDRATE_ARRAY);
return $resultArray;
My next question is how to do this exact same thing for a collection? This is what I have tried:
public function fetchAll()
{
$qb = $this->stoneRepository->createQueryBuilder('S');
$qb->addSelect('A','P','I','C')
->leftJoin('S.attribute', 'A')
->leftJoin('A.category', 'C')
->innerJoin('S.product' , 'P')
->innerJoin('S.image' , 'I')
->where('S.state=:state')
->setParameter('state' , 1 );
$adapter = new DoctrineAdapter( new ORMPaginator( $qb ) );
$collection = new StoneCollection($adapter);
return $collection;
}
The problem I am facing with this solution is that the join tables are not being populated and I am ending up with a collection of empty results.
The StoneCollection class simply extends paginator:
<?php
namespace Api\V1\Rest\Stone;
use Zend\Paginator\Paginator;
class StoneCollection extends Paginator
{
}
I am thinking that perhaps the best mehod is to get an array and to page the array?
EDIT::
I have this working although I am not keen on it as I hit the DB twice. The first time to build the array (Which is the entire result set which could be very big for some applications) and then the second time to page the results which is then returned to HAL in ApiGility for processing...
Ideally this should be done in one go however I am not sure how to hydrate the results in a single instance...
public function fetchAll( $page = 1 )
{
$qb = $this->stoneRepository->createQueryBuilder('S');
$qb->addSelect('A','P','I','C')
->leftJoin('S.attribute', 'A')
->leftJoin('A.category', 'C')
->innerJoin('S.product' , 'P')
->innerJoin('S.image' , 'I')
->where('S.state=:state')
->setParameter('state' , 1 );
$resultArray = $qb->getQuery()->getResult(\Doctrine\ORM\Query::HYDRATE_ARRAY);
$paginator = new \Zend\Paginator\Paginator(new \Zend\Paginator\Adapter\ArrayAdapter($resultArray));
$paginator->setCurrentPageNumber($page);
return $paginator;
}
The Answer to this is as I have above:

$resultArray = $qb->getQuery()->getResult(\Doctrine\ORM\Query::HYDRATE_ARRAY);
$paginator = new \Zend\Paginator\Paginator(new \Zend\Paginator\Adapter\ArrayAdapter($resultArray));
$paginator->setCurrentPageNumber($page);
return $paginator;
}
On the Doctrine documentation for Pagination they state to use $fetchJoinCollection = true, which I believe is the same as the HYDRATE you are trying to use.
Doctrine Pagination
On my pagination code for my QueryBuilder I use it like the following:
public function getAllPaginated($page, $limit){
$query = $this->createQueryBuilder('o')
->select('o')
->getQuery();
$paginator = new Paginator($query, $fetchJoinCollection = true);
$paginator->getQuery()
->setFirstResult($limit * ($page - 1)) // Offset
->setMaxResults($limit);
return $paginator;
}
I am using symfony2 and Query builder. I get mixed results as a result of my query that follows. I know this is due to using aggregate functions in SELECT, but I DO NOT find any other way and this is exactly what I need. Any direction would be gratefully appreciated:
public function Inventory() {
$em = $this->getEntityManager();
$qb = $em->createQueryBuilder();
$qb
->add('select', 'i.id, i.name, SUM(pod.quantityorder) as quantityordered, SUM(it.quantity) as quantityreceived')
->add('from', 'AutokeenPurchasingBundle:Items i')
->leftJoin('i.purchase_order_details', 'pod')
->leftJoin('i.inventory_transactions', 'it', 'WITH', 'it.inventory_transaction_type = 1')
->add('groupBy', 'i.id')
->addGroupBy('it.item')
->addGroupBy('pod.item')
->add('orderBy', 'i.id');
$query = $qb->getQuery();
$query->useResultCache('my_cache_id');
return $result = $query->getScalarResult();
}
New to Symfony2 and Doctrine2, i have a function in my entity repository to search entities after form submission. Input is array $get that contain form fields like $get['name'] = 'aname'.
My problem is that when i request with an id, or an id and a name, it's ok by with only a name, all my entities are matched because the query that has been build have no where clause.
Here is my code :
public function search(array $get, $flag = False){
/* Indexed column (used for fast and accurate table cardinality) */
$alias = 'd';
/* DB table to use */
$tableObjectName = 'mysiteMyBundle:DB';
$qb = $this->getEntityManager()
->getRepository($tableObjectName)
->createQueryBuilder($alias)
->select($alias.'.id');
$arr = array();
//Simple array, will grow after problem solved
$numericFields = array(
'id');
$textFields = array(
'name');
while($el = current($get)) {
$field = key($get);
if ( $field == '' or $field == Null or $el == '' or $el == Null ) {
next($get);
}
if ( in_array($field,$numericFields) ){
if ( is_numeric($el) ){
$arr[] = $qb->expr()->eq($alias.".".$field, $el);
}
} else {
if ( in_array($field,$textFields) ) {
$arr[] = $qb->expr()->like($alias.".".$field, $qb->expr()->literal('%'.$el.'%') );
}
}
next($get);
}
if(count($arr) > 0) $qb->andWhere(new Expr\Orx($arr));
else unset($arr);
$query = $qb->getQuery();
if($flag)
return $query;
else
return $query->getResult();
}
The query generated with only a name (ex "myname") input is :
SELECT d0_.id AS id0 FROM DB d0_
It should be:
SELECT d0_.id AS id0 FROM DB d0_ WHERE d0_.name LIKE '%myname%'
What's wrong with my code ?
Thanks !
I don't know if it's related, but do not use "OR" or "AND" operators, because they have a different meaning that the classic "&&" or "||". cf http://php.net/manual/en/language.operators.logical.php
So, first, replace "AND" by "&&", and "OR" by "||".
you should use the setParameter method
$query->where('id = :id')->setParameter('id', $id);
I am using CodeIgniter2 + Doctrine2, and have the following query:
$query = $this->doctrine->em->createQuery("
SELECT u
FROM ORM\Dynasties2\Characters u
WHERE u.fathersId = $key
AND u.deathDate IS NULL
AND u.isRuler = '0'
AND u.isFemale = '0'
AND u.useAI = '1'
AND u.bornDate <= $of_age
");
$sons_of_age = $query -> getResult();
And I only want to get ONE result, assuming there are any hits.
I've looked at Doctrine documentation about using ->LIMIT(1) but I have tried putting this into my query in various places, and only get errors.
Codeigniter has some functions builtin to do $query->row() but this does not seem to work - I wager because of the Doctrine integration.
Thanks!
You're looking for method Query::setMaxResults($number); Then you can use Query:getSingleResult();, but method Query:getSingleResult(); throws error if there's no record.
$query = $this->doctrine->em->createQuery("
SELECT u
FROM ORM\Dynasties2\Characters u
WHERE u.fathersId = $key
AND u.deathDate IS NULL
AND u.isRuler = '0'
AND u.isFemale = '0'
AND u.useAI = '1'
AND u.bornDate <= $of_age
");
$query->setMaxResults(1);
try {
$sons_of_age = $query->getSingleResult();
} catch (\Doctrine\ORM\NoResultException $e) {
$sons_of_age = null;
}
