We know who directed a specific movie because there is a column director_id in the table movie. If you take a look at "Midnight in Paris", its director_id is 3. So we can now look into directors to find out that id 3 is assigned to Woody Allen. And that's how we know he is the director. Did you get that right?
There are quite a few ways of getting information from multiple tables at the same time. We're going to start with the easiest one.
SELECT * FROM person, car;
Syntax :
SELECT * FROM table1, table2;
You already know how SELECT * FROM works, don't you? Now we just name two tables instead of one, and we separate them with a comma (,). Piece of cake! The result, however, might be a tiny bit of a surprise to you. Let's check that out.
Excercide-
Select all data from table movie and table director;
SELECT * FROM movie, director;
