SQL Basics

How to query more than one table
Creating JOINs
6. Join tables using JOIN
Referencing columns
Let's practice

Instruction

Take a look at the following example:

SELECT *
FROM person
JOIN car
  ON person.id = car.owner_id;

We want to join the tables person and car, so we use the keyword JOIN between their names.

SQL must also know how to join the tables, so there is another keyword ON. After it, we set our condition: join only those rows where the id in person is the same as owner_id in car.

Exercise

Use the new construction JOIN ... ON to join rows from the tables movie and director in such a way that a movie is shown together with its director. Display all columns from both tables.

Stuck? Here's a hint!

Type:

SELECT *
FROM movie
JOIN director
  ON movie.director_id = director.id;
