entitymanager

I need to perform this query: SELECT * FROM (SELECT * FROM product WHERE car = 'large' ORDER BY onSale DESC) AS product_ordered GROUP BY type In Symfony2 using the entity manager. My basic query builder would be : $query = $em->getRepository('AutomotiveBundle:Car') ->createQueryBuilder('p') ->where('pr.car = ?1') ->andWhere('pr.status = 1') ->orderBy('pr.onSale', 'DESC') ->setParameter(1, $product->getName()) ->groupBy('p.type') ->getQuery(); But I cannot work out how to add in a subquery to this. Ive tried making a separate query and joining it like: ->andWhere($query->expr()->in('pr.car = ?1

I've built some JPA stuff in the past that used an instance of the javax.persistence.EntityManager per instance of DAO; this is the way most examples are setup. public class BaseDaoThatEveryDaoExtends { @PersistenceContext private EntityManager entityManager; } I've just stumbled upon code that uses a static javax.peristence.EntityManger injected by a PersistenceContext annotation, the architect tells me this causes no problems and they never had any problem even in a clustered application with JTA and an XA data source: public class BaseDaoThatEveryDaoExtends { @PersistenceContext private

I'm trying to map a non-entity pojo with the createNativeQuery method of entityManager of jpa. By using something like this @SqlResultSetMapping(name="ResultMapping", classes={ @ConstructorResult( targetClass=Employee.class, columns={ @ColumnResult(name="empID", type=Long.class), @ColumnResult(name="empName", type=String.class), } ) } ) public class Loader{ private EntityManager em; public void load(){ Query query = em.createNativeQuery("select empID, empName from employee", "ResultMapping"); List<Employee> = query.getResultList(); } } public class Employee{ private long empID; private String

I want to make a fetchAll() with limit ? Do you know if it's possible with the entity manager of symfony2 ? My current code (Fetch all, without limit): $repository = $this->getDoctrine()->getRepository('MyBundle:Download'); $product = $repository->findAll(); Thanks you all. Best regards, EDIT: $em = $this->getDoctrine()->getRepository('MyBundle:Download'); $ouput = $em->findBy(array(), array('id' => 'DESC'),5); Return the 5 last rows. Thanks all. It's often instructive to check the source code. Doctrine\ORM\EntityRepository public function findAll() { return $this->findBy(array()); } public

Overview: I'm building a spring-boot application which, in part, retrieves some entities from an external REST service and compares it to previous versions of the entity held locally in a database. I'm injecting EntityManager with @PersistenceContext , and using that to work with the database, as there are many entity types, and the type is initially unknown to the module. I could get a JpaRepository from a factory, but the number of different entity types is liable to grow, and I'd rather not rely on that if at all possible. Problem: When the module retrieves an entity which it doesn't hold

I have one jar library A (or project in eclipse), which has it's own persistence unit (META-INF/persistence.xml) and some entity classes, and another project (B) using this one. In project B there is also persistence unit and entity classes. In project B I need to use both entity classes from project A and B. But if I set "A" as persistence unit name, EntityManager cannot create named query if this query is in entity from project B. If I set "B" as persistence unit name, it cannot create named queries from entities from project A. Error message is: NamedQuery of name: MyEntityName.myQueryName

I am new to Spring MVC. I've been searching for few days for a solution to my problem, without any success. Here is my stack: jBoss 4.2.3GA server I know it's a very old version, but that is what I am limited to right now. jBoss 7.1 will be approved for use in my organization within the next few months, but I would like to make my R&D application work in the 4.2.3GA server. That means I have added all required jars in my /lib folder. Spring MVC 4.0.2 EJB3.0 / JPA for persistence DBMS is PostgreSQL 9.0.3 I am not using any build/dependency management tool such like Maven or Gradle. Gradle is in
