What is a proper naming convention for MySQL FKs?

Question

Being that they must be unique, what should I name FK\'s in a MySQL DB?

Answer 1

fk-[referencing_table]-[referencing_field]

The reason is the combination of referencing_table and referencing_field is unique in a database. This way make the foreign key name easy to read, for example:

table `user`:
    id
    name
    role

table `article`:
    id
    content
    created_user_id /* --> user.id */
    reviewed_user_id /* --> user.id */

So we have two foreign keys:

fk-article-created_user_id
fk-article-reviewed_user_id

Adding user table name to foreign key name is reduntdant.
