Add a foreign key from completions to enrollments, linking through user_id and course_id to ensure data consistency.

Expected output

ALTER TABLE completions ADD COLUMN course_id INT, ADD CONSTRAINT fk_completions_user_course FOREIGN KEY (user_id, course_id) REFERENCES enrollments(user_id, course_id);

Model output

ALTER TABLE completions ADD COLUMN course_id INT;
UPDATE completions SET course_id = (SELECT course_id FROM lessons WHERE lessons.lesson_id = completions.lesson_id);
ALTER TABLE completions ADD CONSTRAINT fk_completions_enrollments FOREIGN KEY (user_id, course_id) REFERENCES enrollments(user_id, course_id);
