使用联接定义 JPA 存储库本机查询

Question

我有一个带有 Class Ride 的 Spring 项目

Entity
@Table(name = "ride")
public class Ride {
    @Id
    @GeneratedValue
    private Long id;
    @Temporal(TemporalType.TIMESTAMP)
    @Column(name="start_date")
    private Date startDate;
    @Temporal(TemporalType.TIMESTAMP)
    private Date endDate;
    private int nbPlaces;
    private int price;
    public int rank;
    @Column(name="departure_country")
    private String departureCountry;
    @Column(name="departure_city")
    private String departureCity;
    @Column(name="arrival_country")
    private String arrivalCountry;
    @Column(name="arrival_city")
    private String arrivalCity;
    private String appointmentAddress;
    @ManyToOne(optional = false)
    @JsonIgnore
    private Travel travel;
    <.....>    
}

当我使用原生 sql 查询创建存储库时

public interface RideRepository extends JpaRepository<Ride,Long> {

    @Query(value = "SELECT departureQuery.travel FROM (SELECT DISTINCT travel FROM ride WHERE departure_city LIKE %?0% AND start_date > ?2 OR departure_country LIKE %?0% AND start_date > ?2) departureQuery JOIN (SELECT DISTINCT travel FROM ride  WHERE arrival_city LIKE %?1% AND start_date > ?2 OR arrival_country LIKE %?1% AND start_date > ?2) arrivalQuery on departureQuery.travel = arrivalQuery.travel", nativeQuery = true)
    List<Long> find(String departureCity, String arrivalCity, String date);

} 

• 第一个 FROM 带有下划线：需要标识符，得到 '('
• 第二个 SELECT 带有下划线：'SELECT' unexpected

当我尝试部署 war 文件时，我得到了 HTTP 状态 500，

感谢您的帮助。

查询参数的索引从 1 开始，而不是 0。 将“LIKE %?0%”更改为“LIKE %?1%” 相应更改其他参数索引
