Incomplete SQL is generated for update and delete statements. For example, having two entities, user: @Entity @Table(name = "users" ) public class User { @Id @GeneratedValue public Long id; public String name; public User( String name) { this.name = name; } } And comments: @Entity @Table(name = "comments" ) public class Comment { @Id @GeneratedValue public Long id; public String text; @ManyToOne @JoinColumn(name = "user_id" ) @NotFound(action = NotFoundAction.IGNORE) // <-- issue appears when @NotFound is added public User user; public Comment( String text, User user) { this.text = text; this.user = user; } } And following HQL/JPQL statements: * SELECT c FROM Comment c WHERE c.user = :user * UPDATE Comment c SET c.text = :text WHERE c.user = :user * DELETE FROM Comment c WHERE c.user = :user Selects are working and generate correct SQL - select ... from comments c1_0 left join users u1_0 on u1_0.id=c1_0.user_id where u1_0.id=?. However update and delete statements are incomplete (the join part is not included), resulting in invalid SQL - delete from comments where u1_0.id=?. When @NotFound is removed from the association then all examples work, the SQL is generated same way as in Hibernate 5, without join - delete from comments where user_id=?. Test case reproducing these examples - https://github.com/aivish/hibernate-test-case-association-comparisons/tre... , it contains tests for Hibernate 5 and 6, the update/delete ones are failing in Hibernate 6, but working in 5. I see that there are similar issues: * https://hibernate.atlassian.net/browse/HHH-16518 * https://hibernate.atlassian.net/browse/HHH-16615 * https://hibernate.atlassian.net/browse/HHH-15593 Seems like this provides a bit different use case and simpler test case how to reproduce the issue, so decided to create a separate issue.
