Hey!

Something you may want to do every now and then, especially as we write longer queries, is add comments.

A comment is something that won't run, but you can read later on. They can be very useful for yourself (if you come back to a query after a few days or weeks), but also for anyone else reading your queries.

To write a comment in SQLite, we precede the text with two dashes, like this:

-- This is a comment.
-- The line below is not a comment.
CREATE TABLE users (first_name TEXT, surname TEXT);

You may see comments every now and then in SQL queries, so it's handy to know about them!

Kind regards,

Jose
