Id field being named "id" despite the @column tag
Hello,
I am using openjpa 2.2.0
I have an entity with a string primary key called name.
@Entity
@Table(name = "Domain")
public class Domain implements java.io.Serializable, Comparable<Domain> {
....
....
@Id
@Column(name = "name")
public final String getName() {
return this.name;
}
}
Still, when I see the generated sql I see this:
Unknown column 't0.id' in 'field list' {prepstmnt 616432710
SELECT t0.id, bla bla bla bla FROM Domain t0} [code=1054, state=42S22]
shouldnt the sql be SELECT t0.name, bla bla bla FROM Domain t0 ??
in case it matters, the classes are enhanced using the maven plugin.
Greetings

As it has been answered numerous times before, you can't have a final
method. Please, remove final.
I believe the reason that OpenJPA is trying to query t0.id is that we're
using a Datastore identity[1] because as far as the runtime is concerned,
you don't have an ID annotated.
Thanks,
