It is possible that this might be fixed? https://hibernate.atlassian.net/browse/HHH-16414 We have an issue where it seems that all of a sudden , once last week and now yesterday again. Hibernate generates a query where it uses wrong alias, when trying to find relations to “person“, by using “aktør“ (a kind of ident). When we restart the application, it works again. It generates: *join aktoer a1_1 on a1_0* select ... from po_sivilstand s1_0 where s1_0.fk_po_person_id in(select p1_0.id from po_person p1_0 join aktoer a1_1 on a1_0.aktoer_id=p1_0.fk_aktoer_id where p1_0.fk_aktoer_id=$1) Code: interface PersonRepository : JpaRepository<Person, Long> { @Query( "SELECT p FROM Person p" + " WHERE p.aktør = :aktør" ) fun findByAktør(aktør: Aktør): List<Person> } @EntityListeners(RollestyringMotDatabase::class) @Entity(name = "Aktør") @Table(name = "AKTOER") data class Aktør( @Id @Column(name = "aktoer_id", updatable = false, length = 50) @Pattern(regexp = VALID_REGEXP) val aktørId: String, ) : BaseEntitet() { ... } @EntityListeners(RollestyringMotDatabase::class) @Entity(name = "Person") @Table(name = "PO_PERSON") data class Person( @Id @GeneratedValue(strategy = GenerationType.SEQUENCE, generator = "po_person_seq_generator") @SequenceGenerator(name = "po_person_seq_generator", sequenceName = "po_person_seq", allocationSize = 50) val id: Long = 0, @JsonIgnore @ManyToOne(optional = false) @JoinColumn(name = "fk_aktoer_id", nullable = false, updatable = false) val aktør: Aktør, @OneToMany(mappedBy = "person", cascade = [CascadeType.ALL], fetch = FetchType.EAGER) // Workaround før Hibernatebug https://hibernate.atlassian.net/browse/HHH-1718 @Fetch(value = FetchMode.SUBSELECT) var sivilstander: MutableList<GrSivilstand> = mutableListOf(), ... ) : BaseEntitet() { ... } ( https://hibernate.atlassian.net/browse/HHH-16518#add-comment?atlOrigin=ey... ) Add Comment ( https://hibernate.atlassian.net/browse/HHH-16518#add-comment?atlOrigin=ey... ) Get Jira notifications on your phone!
