Many to Many relationships

Many to Many relationships

Many to Many relationships

(OP)
Hi I am not able to create relationships between tables .can any one tell me why I am not able to do that.what I am doing is I have two tables between which I have to have a many to many relationship.When I drag and drop primary key of one table into another i get a relationship box and i dont knwo how to proceed from there.Also referential integrity is disabled and I cannot click on it..why?PLease explain

RE: Many to Many relationships

To implement a many-to-many relationship, you need to create a third table, called a junction table or intersection table, containing the primary keys of both the tables being joined. Then, create the relationships between each of the original tables and the new junction table.

Hope this helps...
