I am using Eclipselink v2.3.3
I am getting this error
Error compiling the query [Credential.updateExistingCredentialNoPW: UPDATE Credential c SET c.active = :active, c.employee.address.streetAddress = :stadd, c.employee.address.city = :city, c.employee.address.province = :prov, c.employee.address.zip = :zip WHERE c.id = :id], line 1, column 46: invalid navigation expression [c.employee], cannot navigate association field [employee] in the SET clause target.
when I try to run my code.
Here are the affected named queries that prevents running my code
#NamedQuery(name = "Credential.updateExistingCredentialNoPW",
query = "UPDATE Credential c "

Am I doing it wrong?
It is not possible to update multiple tables with single sql query.
See https://forums.oracle.com/forums/thread.jspa?threadID=2223393.
So it's also not possible with Eclipselink.
You'll have to split this it two queries, or better use setters.
You can't. Either use a SQL query, or use Java code:
Credential c = em.find(Credential.class, credentialId);
c.setActive(active);
c.getEmployee().getAddress().setStreet(street);

I have a query where i am joining two entities java (tables ) Command and User. I create sql hql query with left join and i get an org.hibernate.hql.ast.QuerySyntaxException: unexpected token error
I think that i have a problem with my left join syntax and also my second select.
My entities
#Entity
#Table(name = "Users")
public class User {
private int idUser;
private String login;
private String password;
private List<Command> commands = new ArrayList<>();
public User() { }
public User( String login, String password ) {
super();
this.setLogin( login );
this.setPassword( password );
}
#Id
#Column(name = "USER_ID", unique = true, nullable = false, scale = 0)
public int getIdUser() {
return idUser;
}
#Column(name = "USER_LOGIN", nullable = false)
public String getLogin() {
return login;
}
public void setLogin(String login) {
this.login = login;
}
#Column(name = "USER_PASSWORD", nullable = false)
public String getPassword() {
return password;
}
public void setPassword(String password) {
this.password = password;
}
#OneToMany(fetch = FetchType.LAZY, mappedBy = "utilisateur")
public List<Command> getCommands() {
return commands;
}
public String toString() {
return this.idUser + ": " + this.login + "/" + this.password
;
}
}
#Entity
#Table(name="Commands")
public class Command {
private int idCommand;
private User utilisateur;
private Date commandDate;
public Command() {}
public Command( User user, Date commandDate ) {
this.setUser( user );
this.setCommandDate( commandDate );
}
#Id
#Column(name = "CMD_Id", unique = true, nullable = false, scale = 0)
public int getIdCommand() {
return idCommand;
}
#ManyToOne(fetch = FetchType.LAZY)
#JoinColumn(name = "USER_ID")
public User getUtilisateur() {
return user;
}
public void setUtilisateur(User user) {
this.user = user;
}
#Column(name = "CMD_DATE")
#Temporal(TemporalType.TIMESTAMP)
public Date getCommandDate() {
return commandDate;
}
public void setCommandDate(Date commandDate) {
this.commandDate = commandDate;
}
public String toString() {
StringBuilder builder = new StringBuilder();
builder.append( "Commande de >> " ).append( this.user )
.append( " - " ).append( this.commandDate ).append( "\n" );
return builder.toString();
}
}
And my hql query
select us.login,us.password
from User us left join Command cmd on us.idUser = cmd.utilisateur.idUser
AND us.idUser not in (SELECT utilisateur.idUser from Command )
ORDER BY us.idUser desc
I don't know what is the problem with my hql query. I Use the entity java in my hql query. AnyOne can i tell me how can i write correctly my hql query with a good syntax hql.
If you need the users login and password of users without commands the following might help
select us.login,us.password
from User us
where us.idUser not in (select c.user.idUser from Command c)
order by us.idUser desc
I have two tables in my oracle database
my table data base
And two entities user and command
#Entity
#Table(name = "Users")
public class User {
private int idUser;
private String login;
private String password;
private List<Command> commands = new ArrayList<>();

super();
this.setLogin( login );
this.setPassword( password );
}
#Id
#Column(name = "USER_ID", unique = true, nullable = false, scale = 0)
public int getIdUser() {
return idUser;
}
#Column(name = "USER_LOGIN", nullable = false)
public String getLogin() {
return login;
}
public void setLogin(String login) {
this.login = login;
}
#Column(name = "USER_PASSWORD", nullable = false)

return password;
}
public void setPassword(String password) {

}
}

public Command() {}
public Command( User user, Date commandDate ) {
this.setUser( user );
this.setCommandDate( commandDate );
}
#Id

}
and my service java class
#Service
#Transactional
public class MyServiceImpl implements MyService {

private static final String MY_ADVANCED_REQUEST

String query1 = MY_ADVANCED_REQUEST;
SQLQuery queryObj = sessionFactory.getCurrentSession().createSQLQuery(query1);
List<Object> lstObj =queryObj.list();
return lstObj;
}
}
I get an empty list in this line List lstObj =queryObj.list(); .
I use a request SQLQuery native not jpa.
I want to get 1 object for us.USER_ID = 5(even if I don't have an us.USER_ID = 5 in table commands), 3 objects for us.USER_ID=1 (because 3 rows in Commands table); 1 object for us.USER_ID=6 (because 1 rows in Commands table)
How can i solve my problem to return a valeur for my us.USER_ID = 5 ?
Left outer join returns all the rows from first table and only matched rows from second table.(though the user_id=5 is not present in commands table it can be retrieved)
private static final String MY_ADVANCED_REQUEST
="select us.USER_ID, cd.CMD_DATE, us.USER_PASSWORD " +
"from Users us LEFT JOIN Commands cd ON us.USER_ID = cd.USER_ID ";
I am using a native query in JPA repository inside #Query annotation

Page<Message> getLatestMessageFromThread(#Param("type") String type, Pageable page);
The problem is when i execute this query i am getting syntax error. When i checked the logs it is showing that the query to take count of total messages in query is like below
select count(where) from message where id in(select if(coalesce(a.maxId,0)>coalesce(b.maxId,0),
a.maxId, b.maxId) maxId from (select from_number, to_number, max(id) maxId,direction,type from

where direction = 'OUTGOING' and schedule_id is null group by from_number, to_number) as b

The count(*) is replaced by count(where)

Why it is getting replaced. How can i write the query in correct way ?
The solution is to use countQuery annotation parameter :
public interface Repository extends JpaRepository<Entity, Long> {
String QUERY = "FROM entity " +
" WHERE name ILIKE :name ";
#Query(
value = "SELECT * " + QUERY,
countQuery = "SELECT count(*) " + QUERY,
nativeQuery = true
)
Page<KDeploymentView> findBy(
#Param("name") String name,
Pageable p
);
I am new to hql and trying to delete the complete row in case of a match based on email.
Following is what I have tried.
Still I get a Persistence Exception.
public void unsubscribeEmailList(EmailListDto dataList) {
EmailList e =new EmailList(dataList);
Query q =sessionFactory.getCurrentSession().createQuery("delete from EmailList where email=:e");
q.setParameter("e", dataList);
int i=q.executeUpdate();
System.out.println(i);
}
Class EmailList is
#Entity
#Table(name = "email_list")
public class EmailList implements Serializable {
private static final long serialVersionUID = 1L;
private Integer id;
private String email;
public EmailList(EmailListDto dto)
{
this.email=dto.getEmail();
}
#Id
#GeneratedValue(strategy = IDENTITY)
#Column(name = "id", unique = true, nullable = false)
public Integer getId() {
return id;
}
public void setId(Integer id) {
this.id = id;
}
#Column(name = "email", nullable = false)
public String getEmail() {
return email;
}
public void setEmail(String email) {
this.email = email;
}
}
Try use this:
q.setParameter("e", e.getEmail());
public void unsubscribeEmailList(EmailListDto dataList) {
EmailList e =new EmailList(dataList);
Query q =sessionFactory.getCurrentSession().createQuery("delete from EmailList where email = :e");
q.setParameter("e", e.egetEmail() );
int i=q.executeUpdate();
System.out.println(i);
}

If I understand correctly, you have the ID of a user, and you want to get the friends of the user identified by this ID. The easiest way is to do
Scuser user = em.find(User.class, userId);
Collection<Scuser> friends = user.getScuserCollection();
If you want to do it using a JPQL query, you just need
select friend from Scuser user
inner join user.scuserCollection friend
where user.id = :userId
Note that your mapping isn't right: scuserCollection1 and beachCollection are both mapped by the same attribute. You should also choose better names for your associations (like friends for example, instead of scuserCollection).
