Challenge: Table Join

メニュヌを衚瀺するにはスワむプしおください

In this task, you'll need to use a different type of JOIN, or you can use the same one you used in the previous chapter, as long as you get the correct result.

タスク

スワむプしおコヌディングを開始

Write a query to retrieve a list of all students and the courses they are enrolled in, including students who are not enrolled in any course.

Use an appropriate type of JOIN and use the columns in the following order:

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

As you can see, there are no aliases here, so do not use them to ensure the task is correctly evaluated.

Brief Instructions

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