FULL JOIN Usage
In this chapter, you will need to use a specific type of table join, unlike the previous two chapters where, in theory, you could use the same type of JOIN.
I will remind you that we are working with two tables:
courses:
| course_id | course_name | description |
|---|---|---|
| 1 | Introduction to Programming | Learn the basics of programming using Python. |
| 2 | Data Structures and Algorithms | In-depth study of data structures and algorithms. |
| 3 | Web Development | Learn how to build web applications using HTML, CSS, and JavaScript. |
| 4 | Database Management | Understand database concepts and SQL. |
| ... | ... | ... |
| 11 | DevOps Fundamentals | Learn the principles and practices of DevOps. |
enrollments:
| enrollment_id | student_name | course_id | enrollment_date |
|---|---|---|---|
| 1 | Alice Johnson | 1 | 2023-01-15T00:00:00Z |
| 2 | Bob Brown | 2 | 2023-01-20T00:00:00Z |

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