Class Department   {
...
private Set students;
....
}

Class Student  {
...
private Set depts;
....
}

Now, if I want to delete entries related to a
particular Department using HQL, can I do the following:

"delete from Department.students ......"

or
//define values and types
.....
String hql = "select dept.students from Department as dept .....";
session.delete(hql, values, types);

I am wondering if the above cases hold true? Otherwise how can I achieve this?

thanks,
