Any problems if foreign key is defined in the table creation SQL script?

In cakephp, the table relationship is defined in the Models and no foreign key needs to be defined in the table creation SQL script. However, I have a SQL script created using MySQL workbench that defines the foreign key. Will this be a problem in cakephp?
