Enter a review for E.T. Use a username and review of your choosing.

The scheme for reviews doesn't have a title column, only a column for the movie ID.

This task is asking me to insert a review into that data base for ET.

Say I didnt have the movie ID? Or I just didnt want to look it up just so I could insert the value appropriately into the reviews data base.

Is there some way to link the two tables and say "Insert a review for ET by inserting the id that the movie is linked to, then insert username, review, and rating?"

Maybe that's asking two much for one line of code. but I feel like there has to be a simpler way to accomplish this.

Here's an explanation from w3schools of INSERT INTO SELECT and an explanation of literals from geeksengine.com

INSERT INTO reviews (movie_id, username, review, rating)
SELECT movie_id, "my username", "my review", my rating
FROM movies
WHERE title = "E.T.";

If it wouldn't be too much trouble, could you break down in words what this is doing?
