Steve Ebersole commented on HHH-7139:
-------------------------------------
Going to reject this/close this as wont fix. It is questionable whether this is a bug.
The JPA is silent on whether this is valid or is not valid. I understand this (this
double mapping of the column) is how other vendors support the idea of a primary key
comprised at least partially of foreign keys, but Hibernate has much more elegant support
for this via a "key many-to-one":
{code:title=Partnership.java|borderStyle=solid}
@Entity
@Table(name = "Partnerships")
@IdClass(value = PartnershipId.class)
public class Partnership implements Serializable {
@Id
@ManyToOne
@JoinColumn(name = "pq_id", referencedColumnName = "id")
private PQ pq;
@Id
@ManyToOne
@JoinColumn(name = "company_id", referencedColumnName = "id")
private Company company;
@Column(name = "ordinal_nbr")
private Integer ordinalNbr;
...
}
{code}
which is also one of the approximately umpteen-million or so variations of "derived
identities" mappings defined by JPA 2.0
Or if you want to remain compliant with those "other vendors" and their JPA 1.0
support, simply reverse the insertable/updatable
java.sql.SQLException: Invalid argument in JDBC call: parameter index
out of range when trying to persist an entity mapped with insertable = false, updatable =
false on @Column
--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
Key: HHH-7139
URL:
https://hibernate.onjira.com/browse/HHH-7139
Project: Hibernate ORM
Issue Type: Bug
Environment: Hibernate 4.0.0.CR4, HSQLDB 2.0, MySQL 5.1
Reporter: Karsten Wutzke
Attachments: hib-readonly-col.zip
The following mappings are all JPA 1.0 compatible (no derived identifiers):
{code:Company.java}
@Entity
@Table(name = "Companies")
public class Company
{
@Id
@Column
private Integer id;
@Column
private String name;
...
}
{code}
{code:PQ.java}
@Entity
@Table(name = "PQs")
public class PQ implements Serializable
{
@Id
@Column
private Integer id;
@Column
private String name;
...
}
{code}
{code:Partnership.java}
@Entity
@Table(name = "Partnerships")
@IdClass(value = PartnershipId.class)
public class Partnership implements Serializable
{
@Id
@Column(name = "pq_id", insertable = false, updatable = false)
private Integer pqId;
@Id
@Column(name = "company_id", insertable = false, updatable = false)
private Integer companyId;
@Column(name = "ordinal_nbr")
private Integer ordinalNbr;
@ManyToOne
@JoinColumn(name = "pq_id", referencedColumnName = "id")
private PQ pq;
@ManyToOne
@JoinColumn(name = "company_id", referencedColumnName = "id")
private Company company;
...
}
{code}
{code:PartnershipId.java}
public class PartnershipId implements Serializable
{
private Integer pqId;
private Integer companyId;
public PartnershipId()
{
}
public PartnershipId(Integer pqId, Integer companyId)
{
this.pqId = pqId;
this.companyId = companyId;
}
...
}
{code}
Note, the insertable = false, updatable = false on @JoinColumn relationships.
Running the following test code
{code:Main.java}
public class Main
{
private static String PERSISTENCE_UNIT_NAME = "standalonePu";
private static EntityManagerFactory emf;
private static EntityManager em;
private static EntityTransaction trans;
public static void main(String[] args)
{
setUp(PERSISTENCE_UNIT_NAME);
trans.begin();
PQ detachedPq = new PQ(1, "Test PQ");
Company detachedCompany = new Company(1, "Test Company");
PQ pq = em.merge(detachedPq);
Company company = em.merge(detachedCompany);
Partnership detachedPartnership = new Partnership(1, 1, 1);
detachedPartnership.setPQ(pq);
detachedPartnership.setCompany(company);
Partnership partnership = em.merge(detachedPartnership);
partnership = em.find(Partnership.class, new PartnershipId(1, 1));
System.out.println("Persistent partnership = ("
+ partnership.getPQId() + ", "
+ partnership.getCompanyId() + ", "
+ partnership.getOrdinalNbr() + ")");
trans.commit();
close();
}
private static void setUp(String puName)
{
emf = Persistence.createEntityManagerFactory(puName);
em = emf.createEntityManager();
trans = em.getTransaction();
}
private static void close()
{
em.close();
emf.close();
}
}
{code}
fails with a really strange exception:

I've also tested this with MySQL with the same JDBC exception.
Note the workaround to resolve this is to put `..., insertable = false, updatable =
false` onto the relationships' `@JoinColumn`s (but it's not really what I want).
Please fix.
