Question

我在jpa和hibernate中使用spring boot 2。我尝试删除。

我的课

public Scpi{
    @Id
    ....
    private Integer id;

    @ManyToMany(mappedBy = "scpi")
    private Set<Asi> asi = new HashSet<>();

    ...
}

public Asi{
    @Id
    ....
    private Integer id;

    @ManyToOne
    private Spi spi;

    ...
}

我的删除

@Modifying
@Query("delete from Scpi scpi where scpi.id in ( select spci2.id from Scpi scpi2 inner Join spci2.asi asi inner Join asi.spi spi where spi.id= ?1)")

我得到错误

org.hibernate.hql.internal.ast.InvalidPathException：无效路径： 'spci2.asi'

有什么主意吗？

Answer 1

在您的SQL中似乎有错字，应该是scpi2.asi而不是spci2.asi，并且与scpi2.id相同。

因此正确的删除语句为：

@Modifying
@Query("delete from Scpi scpi where scpi.id in ( select scpi2.id from Scpi scpi2 inner Join scpi2.asi asi inner Join asi.spi spi where spi.id= ?1)")

用子查询删除给出无效的路径
