Instruction

Very well done! Let's do one more exercise.

Exercise

For each student show the room data the student is assigned to. Show also students who are not assigned to any room. Use a RIGHT JOIN.

Stuck? Here's a hint!

Type:

SELECT *
FROM room
RIGHT JOIN student
  ON student.room_id = room.id;
