Hi. I have this table with 3 primary keys and I need to reference it in another table. How?
I was going to just put an id of type int in the monthly fee table to be the only primary key. But each monthly fee must be unique to a contract and have only one record per month / year, so 3 as the primary key.
In the simplest model, I would bind the id that is the primary key to the other table and would create a foreign key, like: id_mensalidade REFERENCES mensalidade(id) . Right?
But how do I do this in this template?
Thanks, if not clear, I can edit the post.
Using MySQL.
