Laravel Migration DELIMITER - mysql

Question

I'm trying to create a MySQL trigger via artisan migration.
DB::unprepared('
DELIMITER $$
CREATE TRIGGER cascade_courseAffinity_after_facultyAffinity
AFTER DELETE ON faculty_affinities
FOR EACH ROW
BEGIN
DELETE ca
FROM course_affinities AS ca
JOIN courses AS course1 ON ca.course1_id = course1.id
JOIN courses AS course2 ON ca.course2_id = course2.id
WHERE (course1.faculty_id = OLD.faculty1_id OR course1.faculty_id = OLD.faculty2_id)
AND (course2.faculty_id = OLD.faculty1_id OR course2.faculty_id = OLD.faculty2_id);
END
$$
');
Nevertheless when I run the migration, I get the error
SQLSTATE[]: Syntax error... near DELIMITER $$ at line 1
Help someone?
Edit 1: this are the migration files i'm using on MySQL

The problem is in the DELIMITER command. This command is intended to use just in MySQL Client. So, you can't use it in Laravel.
Take a time to read this post: Creating MYSQL Procedure in Laravel 4 Migrations
It's a problem very similar to yours.
