I have a many-to-many mapping between student and course and I have cascade="all" on the students-to-courses mapping as shown below. When I delete a student, hibernate cascades the delete to all of the students courses. My problem is that some of these deleted courses are also shared by other students. How do I ensure that deleting student_A will delete only courses that belong only to student_A and not courses that are shared with student_B.
