-------------------------------------------------------------
I disagree with not fixing this one. I have seen many situations in which new JPA 2.0
style derived identities cause horrible mapping exceptions, essentially making the
underlying ORM useless with these mappings. OTOH I don't see why the above mappings
should not be working, given that the read-only properties are clearly better put onto the
redundant @Column fields. At least, this would be much more natural and is just another
barrier to get over for beginners.
Not supporting JPA 1.0 is a big concern IMO. I found that the JPA 1.0 are more stable on
both Hibernate and EclipseLink. Please don't consider derived identities a full
replacement for the JPA 1.0 style mappings.

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.
