Foreign Key Constraint Definition

From the New Foreign Key Constraint dialog you can define a foreign key for a table. You can add a new constraint, view a constraint definition, or remove a constraint. You cannot, however, change the constraint definition once the constraint is created. If you want to change a foreign key constraint, you must first delete the constraint and then recreate it.
