Query Quest PostgreSQL Course

Hello, SQL!

PostgreSQL is a database: a place to store information in organized tables. SQL is the language you use to talk to it. Your first command asks PostgreSQL to return a value.

What you'll learn

SELECT chooses what you want to see. AS gives the output column a friendly name. Strings go inside single quotes.

Your mission

Return the text 'Hello, PostgreSQL!' in a column named message.
