字段列表中的NativeQuery未知列

Question

@Query(value = "SELECT r FROM Reservation r WHERE r.reservationSeance.id=:seanceId " +
            "AND r.seanceDate=:seanceDate " +
            "order by r.id DESC LIMIT 1", nativeQuery = true)
public Reservation findReservationBySeanceDateAndSeanceId(@Param("seanceId") int seanceId, @Param("seanceDate") java.time.LocalDate seanceDate);

Without nativeQuery as parameter I have error ',' or nulls expected, got LIMIT stackoverflow but when using it and set true i have error

com.mysql.jdbc.exceptions.jdbc4.MySQLSyntaxErrorException: Unknown column 'r' in 'field list'

EDIT: Entity used in query

@Entity
@Table(name="reservation")
@Data
@NoArgsConstructor
public class Reservation {

    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    @Column(nullable = false, unique = true)
    private Integer id;

    private java.time.LocalDate reservationDate;
    private java.time.LocalDate seanceDate;

    private Integer reservationNr;

    @ManyToOne(fetch = FetchType.LAZY)
    private Seance reservationSeance;

    @ManyToOne(fetch = FetchType.LAZY, cascade = CascadeType.MERGE)
    @JoinColumn(name = "user_id")
    private User userReservation;

    @OneToMany(orphanRemoval = true, cascade = CascadeType.MERGE)
    private List<Seat> seats = new ArrayList<>();
}

Seance Entity

@Entity
@Table(name="seance")
@Data
public class Seance {
    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    @Column(nullable = false, unique = true)
    private Integer id;

    private java.time.LocalTime displayTime;

    @ManyToOne
    private Film film;

    @Column(length=127)
    private String kind;

    @ManyToOne(fetch = FetchType.LAZY, cascade = CascadeType.MERGE)

    @OneToMany(mappedBy = "reservationSeance")
    @JsonIgnore
    private List<Reservation> reservations = new ArrayList<>();
}

@Query(value = "SELECT * FROM Reservation r WHERE **r.reservationSeanceId**=:seanceId " +
            "AND r.seanceDate=:seanceDate " +
            "order by r.id DESC LIMIT 1", nativeQuery = true)
public Reservation findReservationBySeanceDateAndSeanceId(@Param("seanceId") int seanceId, @Param("seanceDate") java.time.LocalDate seanceDate);

I think this should be something like above. The problem is happening, because you're trying use alias name r then field name reservationSeance , and then also field name id . It's not correct.

Please, provide your table to get more information about your issue. I can suppose, that r.reservationSeance.id it's fk, and in this case, you should use full fk name, which was pointed in your @JoinColumn name annotation.

Updated.

Please, have a look at Reservation or Seance class, there will be relationship annotation. Where you used @OneToMany for example, then should be @JoinColumn name = 'your_fk_name' And then, please, paste this fk_name to query instead of r.reservationSeance.id.
