3.5.beta1: Wrong query generation for @EmbeddedId and @MappedById
-----------------------------------------------------------------
Key: EJB-462
URL: http://opensource.atlassian.com/projects/hibernate/browse/EJB-462
Project: Hibernate Entity Manager
Issue Type: Bug
Affects Versions: 3.5
Environment: Hibernate 3.5.beta1
Reporter: Juergen Zimmermann
I'm having this entity class:
@Entity
@Table(name="reklamation")
@NamedQueries({
@NamedQuery(name = "findReklamationenByKundeId",
query = "SELECT r FROM Reklamation r WHERE r.bestellung.kunde.id = :kundeId ORDER
BY r.bestellung.id")
})
public class Reklamation implements Serializable {
@EmbeddedId
@AttributeOverride(name="bestellungId",
column=@Column(name="bestellung_fk"))
private ReklamationId id = new ReklamationId();
@MappedById("bestellungId")
@ManyToOne
private Bestellung bestellung;
...
@Embeddable
public static class ReklamationId implements Serializable {
public Long bestellungId;
public Date datum;
}
}
The owner class:
@Entity
@Table(name="bestellung")
@NamedQueries({...})
public class Bestellung implements java.io.Serializable {
@Id
@GeneratedValue(strategy=AUTO, generator="bestellung_sequence_name")
@SequenceGenerator(name="bestellung_sequence_name",
sequenceName="bestellung_b_id_seq", allocationSize=1)
@Column(name="b_id", unique=true, nullable=false, precision=20)
private Long id = null;
...
}
The table definitions in PostgreSQL:
CREATE TABLE reklamation(
bestellung_fk BIGINT NOT NULL,
datum DATE NOT NULL,
...
PRIMARY KEY(bestellung_fk, datum),
FOREIGN KEY (bestellung_fk) REFERENCES bestellung(b_id)
);
CREATE TABLE bestellung(
b_id BIGSERIAL NOT NULL PRIMARY KEY,
kunde_fk BIGINT NOT NULL,
...
FOREIGN KEY (kunde_fk) REFERENCES kunde(k_id)
);
The wrong generation of SQL regarding @EmbeddedId and @MappedById:
2009-08-22 09:04:06,469 DEBUG org.hibernate.SQL -
/* named HQL query findReklamationenByKundeId */ select
reklamatio0_.bestellung_fk as bestellung1_34_,
reklamatio0_.datum as datum34_,
reklamatio0_.bestellung_b_id as bestellung4_34_,
reklamatio0_.inhalt as inhalt34_
from
reklamation reklamatio0_,
bestellung bestellung1_
where
reklamatio0_.bestellung_b_id=bestellung1_.b_id
and bestellung1_.kunde_fk=?
order by
reklamatio0_.bestellung_b_id
