Hibernate Join two unrelated table when both has Composite Primary Key

Question

I\'m writing java application using hibernate 5.2 but without HQL

there is two table, Transactions and ResponseCode

Answer 1

Change the relation from @OneToOne to @OneToMany and use fetch instead of join , it will execute only one query and hopefully it works.

 Join join =
        (Join)transaction.fetch("rc",JoinType.LEFT);

and you can try it with @OneToOne too.
