Question

我有两个实体。一个是 MatchTable ，另一个是 MatchLog 。

@Entity
public class MatchTable {

    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    @Column(name = "id", updatable = false, nullable = false)
    private Long id;

    @ManyToOne
    private Integer primaryID;

    @ManyToOne
    private Integer suspectedID;

    @Column(nullable=false)
    private Integer status;

    //getter and setter

}



@Entity
public class MatchLog {

    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    @Column(name = "id", updatable = false, nullable = false)
    private Long id;

    @OneToOne
    private MatchTable referenceID;

    @Column(nullable=false)
    private Long primaryID;

    @Column(nullable=false)
    private Long suspectedID;

    @Column(nullable=false)
    private Integer status;

    //getter and setter
}

如果匹配表的状态发生更改，则这些行将被插入 MatchLog 。我已尝试使用以下 JPQL 查询。

@Query("INSERT INTO MatchLog (referenceID.id,primaryID,suspectedID,status) SELECT id,primaryID,suspectedID,status from MatchTable where (primaryID = :ID or suspectedID = :ID)")
int updateMatchLogTable(@Param("ID") long ID);

但是此 JPQL 查询不起作用。请建议我将插入的行从 MatchTable 更改为 MatchLog 的JPQL查询。

除非我弄错了，否则JPA不支持“插入select”。您可以更改为本地查询。

通过选择查询无法进行JPQL插入
