I have a simple (I guess) problem but I have no idea what's wrong.
I'm trying to execute following HQL query:
String hql = "delete CinemaProgramme program where program.id in (select q.id from CinemaProgramme q left join q.timetable a " +
"where a > :today)";
and I get an error:

However, when I just try to execute the query without the delete:
String hql = "from CinemaProgramme program where program.id in (select q.id from CinemaProgramme q left join q.timetable a " +
"where a > :today)";
Then it works fine....
Subquery itself also works correctly:
String hql = "select q.id from CinemaProgramme q left join q.timetable a " +
"where a > :today)"
........
#Entity
#Table(name = "cinema_programme")
public class CinemaProgramme implements Serializable {
#Id
#GeneratedValue(strategy = IDENTITY)
#Column(name = "id", unique = true, nullable = false)
private int id;
#ElementCollection
#LazyCollection(LazyCollectionOption.FALSE)
#JoinColumn(name = "programme_id")
private List<Date> timetable;
#ManyToOne(cascade= CascadeType.ALL,fetch = FetchType.EAGER)
#JoinColumn(name = "movie_id")
private Movie movie;
}
Any ideas?
PS.
delete from CinemaProgramme AS program - also doesn't work
There are not enough details about the entities. Does this work:
delete CinemaProgramme where id in (select q.id from CinemaProgramme q left join q.timetable a where a > :today)
OR
delete CinemaProgramme where timetable > :today

guys i am making a grid library that uses hibernate and spring mvc to read data from db .. i have 2 table employee which has EPMID, EMPNAME, EMPAGE, SALARY, ADDRESS, department_id (refrences to department_id in department table ) and department which has department_id and name ... here is the Department.java
public class Department {
#Id
#GeneratedValue(strategy = GenerationType.AUTO)
#Column(name = "department_id")
private int depId;
#Column(name = "name")
private String depName;
#OneToMany(mappedBy="department",cascade = { CascadeType.ALL }, orphanRemoval=true)
private List<Employee> employees;}
Employee.java
public class Employee {
#Id
#GeneratedValue(strategy = GenerationType.AUTO)
#Column(name = "EMPID")
private int empId;
#Column(name = "EMPNAME")
private String empName;
#Column(name = "ADDRESS")
private String empAddress;
#Column(name = "SALARY")
private String salary;
#Column(name = "EMPAGE")
private int empAge;
#ManyToOne(cascade={CascadeType.ALL})
#JoinColumn(name="department_id")
private Department department;}
and the function that adds teh employee in service
public void addEmployee(String[] list, Employee employee) {
employee.getDepartment().setDepId(Integer.parseInt(list[3]));
employee.setEmpName(list[2]);
employee.setEmpAge(Integer.parseInt(list[4]));
employee.setEmpAddress(list[6]);
employee.setSalary(list[1]);
this.employeeDao.addOrEditEmployee(employee);
everything goes fine without that line employee.getDepartment().setDepId(Integer.parseInt(list[3])); but i want to add foreign key to reference on the primary one ..
here is the exception
SEVERE: Servlet.service() for servlet [sdnext] in context with path [/Spring3HibernateApp1] threw exception [Request processing failed; nested exception is java.lang.NullPointerException] with root cause

Do NOT maintain foreign keys using something like this
employee.getDepartment().setDepId(Integer.parseInt(list[3]));
Instead do
Department dept = departmentDao.findById(Integer.parseInt(list[3]));
employee.setDepartment(dept);
Hibernate will now create the database relationship between department and employee by inserting the department_id in the employee table.
P.S. I am assuming some class and method names as I do not have all of your code.
Regarding the NPE
I believe you received a null pointer exception because employee doesn't have a department at that point.
employee.getDepartment().setDepId(...
I want to map JPA resultset to a custom POJO.
Below is the code
#SqlResultSetMapping(
name = "SearchVO",
entities = {
#EntityResult(
entityClass = UserInfo.class,
fields = {
#FieldResult(name = "profile_id", column = "id"),
#FieldResult(name = "first_name", column = "firstName"),
#FieldResult(name = "last_name", column = "lastName"),
#FieldResult(name = "email_id", column = "email")
}),
#EntityResult(
entityClass = ProjectVO.class,
fields = {
#FieldResult(name = "project_id", column = "id"),
#FieldResult(name = "project_title", column = "title")
}),
#EntityResult(
entityClass = DemoRealVO.class,
fields = {
#FieldResult(name = "demo_reel_id", column = "reelId"),
#FieldResult(name = "demo_reel_title", column = "title")
})
})
public class SearchVO {
private int profile_id;
private int project_id;
private int demo_reel_id;
private String first_name;
private String last_name;
private String email_id;
private String project_title;
private String demo_reel_title;
// getter and setter
}
Query query = entityManager.createNativeQuery(
"select u.id,u.first_name,u.last_name,p.id,p.title,d.reel_id,d.title from user_info u,projectvo p,demo_realvo d where (concat(u.first_name,' ',u.last_name,' ',p.title,' ',d.title) like lower(:queryString))", "SearchVO");
But it is giving me below error

Please tell me where i am going wrong.
With JPA 2.1, the #SqlResultSetMapping annotation should be placed on an entity class.
Getting java.sql.SQLException: Invalid column name even though column with same name are in table. what can be a reason?
I am trying to call sp with below code:
Session session = HibernateUtil.getSessionFactory().openSession();
Query query = session.getNamedQuery("EMPLOYEE.PRC_HB_EMP_SP1");
query.setParameter("IN_EMPID", empId);
List<Employee> empList = query.list();
System.out.println(empList);
Entity class Employee:
#Entity
#Table(name = "EMPLOYEE")
//#org.hibernate.annotations.NamedNativeQuery(name = "EMPLOYEE.PRC_HB_EMP_SP1", query = "call PRC_HB_EMP_SP1(?,:IN_EMPID)", callable = true, resultClass = Employee.class)
#org.hibernate.annotations.NamedNativeQuery(name = "EMPLOYEE.PRC_HB_EMP_SP1", query = "call PRC_HB_EMP_SP1(?,:IN_EMPID)", callable = true, resultClass = Employee.class)
public class Employee implements Serializable {
private static final long serialVersionUID = -723583058586873479L;
#Id
#Column(name = "EMPID")
private Integer empId;
#Column(name = "EMPNAME")
private String empName;
#Column(name = "ADDRESS")
private String empAddress;
#Column(name = "SALARY")
private Long salary;
#Column(name = "EMPAGE")
private Integer empAge;
............
}
here is sp:
create or replace PROCEDURE PRC_HB_EMP_SP1
(
Out_value OUT SYS_REFCURSOR,
IN_EMPID NUMBER
)
AS
BEGIN
open Out_value for
SELECT EMPID,EMPNAME
FROM EMPLOYEE
WHERE EMPID = IN_EMPID;
END PRC_HB_EMP_SP1;

Your mappings contain columns ADDRESS,SALARY and EMPAGE but those are missing from your SP.You need to include those in your statement.
In my Spring project, I use Spring Security. I have two entities User and UserRole in relation one-to-many. In entities, this relation is unidirectional. I want to get a list of users with Admin role, for example.
My entities:
#Entity
#Table(name = "users")
public class User implements Serializable {
#JoinColumn(name = "userId")
#OneToMany(cascade = CascadeType.ALL, fetch = FetchType.EAGER)
private Set<UserRole> userRoleSet;
}
#Entity
#Table(name = "user_roles")
public class UserRole implements Serializable {
private static final long serialVersionUID = 1L;
#Id
#GeneratedValue
#Column(name = "id")
private Long id;
#Column(name = "name", nullable = false, unique = true, length = 40)
private String name;
}
I use Spring Data. My query is invoked in the method:
#Override
#Transactional(readOnly = true)
public List<User> getAdminList(String username) {
UserRole userRole = new UserRole("ROLE_ADMIN");
return userDao.getAdminList(userRole, username);
}
and the query looks like this:
#Query("select u from User u where :role member of u.userRoleSet and u.username <> :username")
List<User> getAdminList(#Param("role") UserRole userRole, #Param("username") String username);
I try to get users with Admin role using member of expression, but it doesn't work. I get the following exception:
org.springframework.dao.InvalidDataAccessApiUsageException: org.hibernate.TransientObjectException: object references an unsaved transient instance - save the transient instance before flushing: pl.ibank.model.UserRole; nested exception is java.lang.IllegalStateException: org.hibernate.TransientObjectException: object references an unsaved transient instance - save the transient instance before flushing: pl.ibank.model.UserRole

How can I get a user list by role? Earlier I had a bidirectional relation between my entities and everything works fine, but I think that the bidirectional relation is not necessary in this case. How can I solve it with the unidirectional relation?
Try this
#Query("SELECT u FROM User u WHERE u.id IN (SELECT ur.userId FROM UserRole ur WHERE ur.name = :role)")
List<User> getAdminList(#Param("role") String userRole);
And
#Override
#Transactional(readOnly = true)
public List<User> getAdminList() {
String roleName = "ROLE_ADMIN";
return userDao.getAdminList(roleName);
}
Moreover you should refactor your code because naming a method getAdminList and set the role name as parameter is wrong, it should be named something like getUserListByRoleName(String roleName)
EDIT
You should also consider having three tables like : users, user_roles and roles
because now you will duplicate same roles for different users
I am writing an application where i am trying to make an example on hibernate search with Lucene.
In my database, i got an array named A_ROLE witch contains an ID field and a NAME field. Into this array i have store the data bellow:
1 - Agalloh
2 - Rorry Galaher
3 - Isis Isis
My entity class looks like this:
#Entity
#Table(name="A_ROLE")
#NamedQuery(name="ARole.findAll", query="SELECT a FROM ARole a")
#Indexed
public class ARole implements Serializable {
private static final long serialVersionUID = 1L;
#Id
#DocumentId
#SequenceGenerator(name="A_ROLE_ID_GENERATOR", sequenceName="A_ROLE_SEQ")
#GeneratedValue(strategy=GenerationType.SEQUENCE, generator="A_ROLE_ID_GENERATOR")
#Column(unique=true, nullable=false, precision=38)
#Field(index=Index.YES, analyze=Analyze.YES, store=Store.NO)
//#NumericField
private long id;
#Column(length=50)
#Field(index=Index.YES, analyze=Analyze.YES, store=Store.NO)
private String name;
//bi-directional many-to-many association to APermission
#ManyToMany
#JoinTable(
name="A_ROLE_PERMISSION"
, joinColumns={
#JoinColumn(name="ROLE_ID", nullable=false)
}
, inverseJoinColumns={
#JoinColumn(name="PERMISSION_ID", nullable=false)
}
)
private List<APermission> APermissions;
//bi-directional many-to-many association to AUser
#ManyToMany(mappedBy="ARoles")
private List<AUser> AUsers;
constructor, getters and setters
and i have create an interface named DataBaseExchanges which contains a method lucinExample(). This method is responsible for the hibernate search and its implementation is being from the class bellow
import ec.ep.europarl.appdif.db.entity.ARole;
import ec.ep.europarl.appdif.service.DataBaseExchanges;
import java.util.List;
import javax.persistence.EntityManager;
import javax.persistence.PersistenceContext;
import org.hibernate.search.jpa.FullTextEntityManager;
import org.hibernate.search.query.dsl.QueryBuilder;
import org.springframework.stereotype.Service;
import org.springframework.transaction.annotation.Transactional;
#Service("dataSearch")
public class DataBaseExchangesImpl implements DataBaseExchanges {
#PersistenceContext
public EntityManager em;
#Override
#Transactional
public void lucinExample() {
FullTextEntityManager fullTextEntityManager =
org.hibernate.search.jpa.Search.getFullTextEntityManager(em);
//em.getTransaction().begin();
QueryBuilder qb =
fullTextEntityManager.getSearchFactory().buildQueryBuilder()
.forEntity(ARole.class).get();
org.apache.lucene.search.Query query = qb
.keyword()
.onFields("name")
.matching("agalloh")
.createQuery();
// wrap Lucene query in a javax.persistence.Query
org.hibernate.search.jpa.FullTextQuery persistenceQuery =
fullTextEntityManager.createFullTextQuery(query, ARole.class);
// execute search
List result = persistenceQuery.getResultList();
em.close();
}
}
i call this method from a controller, where i have #Autowird the above mentioned interface.
When i debug the above functionality it stops at this line of the implementation code:
org.hibernate.search.jpa.FullTextQuery persistenceQuery =
fullTextEntityManager.createFullTextQuery(query, ARole.class);
with error report:
