Q:

Laravel Migration DELIMITER

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
Create the "courses" table with the one to many relationship to faculty (faculty_id).
Schema::create('courses', function (Blueprint $table) {
                    $table->increments('id');
                    $table->string('name', 150);
                    $table->integer('faculty_id')->unsigned();
                    $table->foreign('faculty_id')->references('id')->on('faculties');
                    $table->boolean('active')->default(1);
                    //$table->softDeletes();
                });

                        $table->string('name', 150)->unique();
                        $table->boolean('active')->default(1);
                        //$table->softDeletes();
                });

Create the "course_affinities" table with the many to many relationship self relationship between courses.

                    $table->increments('id');
                    $table->integer('course1_id')->unsigned();
                        $table->foreign('course1_id')->references('id')->on('courses');
                    $table->integer('course2_id')->unsigned();
                        $table->foreign('course2_id')->references('id')->on('courses');
                    $table->boolean('active')->default(1);
                    //$table->softDeletes();
                });

Create the "faculty_affinities" table with the many to many relationship self relationship between faculties.
    Schema::create('faculty_affinities', function (Blueprint $table) {
                    $table->increments('id');
                    $table->integer('faculty1_id')->unsigned();
                        $table->foreign('faculty1_id')->references('id')->on('faculties');
                    $table->integer('faculty2_id')->unsigned();
                        $table->foreign('faculty2_id')->references('id')->on('faculties');
                    $table->boolean('active')->default(1);
                    //$table->softDeletes();
                });

A:

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.
