bookChallenge: FULL JOIN Usage

In this chapter, you'll learn how to use a different type of table join. Unlike the previous chapters where you could use the same JOIN, this time you'll need to apply a specific one.

Task

Swipe to start coding

Write a query to retrieve a list of all courses and students, including those courses with no registered students and those students who are not registered for any course.

To accomplish this, you will need to use a specific type of join. Also, retrieve the columns in the exact order as specified:

courses.course_id,
courses.course_name,
courses.description,
enrollments.student_name,
enrollments.enrollment_date

Additionally, sort the result by the course_id column. Good luck!

Brief Instructions

  • Retrieve the necessary columns from the courses table.
  • Use a FULL JOIN to join the enrollments table.
  • The common column for both tables is courses.course_id = enrollments.course_id.
  • Sort the results by courses.course_id.
