hi,
I want to add extra columns to the intermediate table which is creating while we doing many to many relationship.
ex:
Student table;
id
name

Course table;
c_id;
title;
what i want to do is

student_course;
id
c_id
registered_date(this is the extra field i want to add)

How can i do it?

thank you

In this case, you might need to break your Many-to-Many association into two One-to-Many associations not only at DB level but also at Object level. So, you will have to design 3 objects one for each of your table.

Take a look at the below URL:
