[hibernate-issues] [Hibernate-JIRA] Created: (HHH-5528) Defining an object with an @ElementCollection prevents bulk delete
Defining an object with an @ElementCollection prevents bulk delete
------------------------------------------------------------------
Key: HHH-5528
URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-5528
Project: Hibernate Core
Issue Type: Bug
Affects Versions: 3.5.4
Reporter: Jacob Rhode
The following query to delete a set of records, only works in some circumstances:
{code}
Query query=em.createQuery("DELETE FROM Person");
query.executeUpdate();
{code}
If you use an @ElementCollection and add some data, this query will fail. Example class:
{code:title=Person.java|borderStyle=solid}
@Entity
@Table(name="person")
public class Person implements Comparable<Person> {
@Id
@GeneratedValue(strategy = GenerationType.AUTO)
@Column(name="id")
private long id = 0;
@ElementCollection
@Column(name = "activation_key")
@CollectionTable(name = "activation_key")
private Set<String> activationKey = new HashSet<String>();
}
{code}
The following error is generated while trying to bulk delete:
{code}
2029 [main] ERROR org.hibernate.util.JDBCExceptionReporter - integrity
constraint violation: foreign key no action; FKCEC6E942485388AB
table: ACTIVATION_KEY
{code}
As a result, this means code that formerly worked using a bulk delete, can stop working
due to an @ElementCollection being added to the associated Java class.
