I have a header(user_header_test) and a detail(user_detail_test) table, where the header table has one-to-many relationship with the detail table. when i want to find and delete the header using EntityManager, it fails. I see that in the generated SQL, the table name has header table name appended with detail table name(i.e DELETE FROM USER_HEADER_TEST_USER_DETAIL_TEST WHERE ..). What I may be doing wrong?. Thanks.
I am using EclipseLink 2.1.1
code snippet:
@Entity
@Table(name = "user_header_test")
@IdClass(UserHeaderPK.class)
public class UserHeader implements Serializable {
@Id
@Column(name = "APP_ID", length = 1000)
private String appId;
@Id
@Column(name = "USER_ID", length = 1000)
private String userId;
@OneToMany(mappedBy = "userHeader", fetch = FetchType.LAZY, cascade = CascadeType.ALL)
private Collection<UserDetail> members = new ArrayList<UserDetail>();
.......
}
@Entity
@Table(name = "user_detail_test")
public class UserDetail implements Serializable {
@Id
@Column(name = "ID")
private int id;
@Column(name = "USER_ADDRESS", length = 1000)
private String address;
@ManyToOne()
@JoinColumns( { @JoinColumn(name = "APP_ID",
referencedColumnName = "APP_ID"),
@JoinColumn(name = "USER_ID",
referencedColumnName = "USER_ID") })
private UserHeader userHeader;
...
}
public class JPATest {
private static EntityManagerFactory emf;
private static EntityManager em;
...
UserHeader userHeader = em.find(...);
em.remove(userHeader);
// The above fails with the exception
/*
Internal Exception: java.sql.SQLSyntaxErrorException: ORA-00972: identifier is too long
Error Code: 972
Call: DELETE FROM USER_HEADER_TEST_USER_DETAIL_TEST WHERE ((APP_ID = ?) AND (USER_ID = ?))
bind => [app,12345]
Query: DataModifyQuery(sql="DELETE FROM USER_HEADER_TEST_USER_DETAIL_TEST WHERE ((APP_ID = ?) AND (USER_ID = ?))")
*/
}
