I have implemented a many to many relationship between two tables using a Link table.When i insert data into these two tables data is automatically inserted into the link table.

But the problem is that in the Link Table, in addition to the Link Fields, I need to maintain Two more fields.

Can anyone tell me how i can insert data into the additional fields while inserting data inti the two main tables.

Thanks...

You have to use two many-to-one relationships and use a type for the link table. So if you currently have two classes "Foo" and "Bar", you need to change it to "Foo" *-1 "FooBarLink" 1-* "Bar".

Thanks.But can't I achieve the same using a Many-To-Many Mapping between the two tables.Or is it not advisable to use Many To Many in such a situation?
