Hi,
Let's say I have the following persistence class:
@Entity
public class B {
@OneToOne(cascade = CascadeType.PERSIST, fetch = FetchType.LAZY)
@JoinColumn(name = "a_id")
private A a;
}
and when I try to execute this JPA query:
SELECT b.a.id FROM B where B.id = 123
my SQL output looks like:
SELECT t1.id FROM table_b t0 INNER JOIN table_a t1 ON t0.a_id = t1.id WHERE
(t0.id = 123)
Why does openJPA add unnecesery JOIN to the SQL query.
Can I somehow change this behaviour of openJPA
Thanks,
QkI
