从另一个列表HQL的列表中选择值

Question

我有一个有很多关系的课程。

Student class { 
@ManyToMany(fetch = FetchType.EAGER) 
private List<Route> routeList;
@ManyToOne
@JoinColumn(name = "idStreet", nullable = false)
private Street idStreet;    
}

Route class {
@ManyToMany(mappedBy = "routeList")
private List<Student> studentList;

@ManyToMany(fetch = FetchType.EAGER)
private List<Street> streetList;
}

Street class {
private long idStreet;
}

我需要使用HQL或函数接收与学生具有相同位置的所有路线。 用sql不起作用。

Answer 1

解决：

Query query = entityManager.createQuery("from Route where :code in 
elements(streetList)");
query.setParameter("codigo", idStreet);
