Hi there,

is there any chance to have AutoIncrement PK Columns in Subtypes? e.g.

Code:

@Inheritance(strategy = InheritanceType.JOINED)
@Entity
public class A{
 @Id @Auto...
 private Integer id;
}


@Entity
public class B extends A{
 @Id @Auto...
 private Integer id;
}

Thanks a lot
Chris

Matdo,

You don't get to specify the ID in the subtypes, it copies the values of the parent.
If the subtypes incremented their values independently, how would you join them with the parent?
