Databases

Hey, I have a question regarding databases especially MySQL.

In the SQL Playground whenever I try to use the MySQL code in the teacher's notes I keep getting errors that those functions like CONCAT() and NOW() don't exist. When I use functions of say PostgreSQL it works normally. So what's wrong?

The playground uses SQLite. Functions available in other databases will not work unless they happen to also be implemented in SQLite.

The Teacher's Notes are for students working in local databases instead of the playground.
