Querying a nullable @OneToOne relationship with JPA (inverse way)

Question

My case is just the converse of this other question: Querying a nullable @OneToOne relationship with JPA

How can I filter the null values of the non-SQL attribute of a @OneToOne relationship on the mappedBy side. The cited question dealt with the @JoinColumn side.

Answer 1

SELECT e2
FROM Entity1 e1 RIGHT OUTER JOIN e1.entity2 e2
WHERE e1 IS NULL
