I know, but your problem is you don't know what is mysql, don't know how to use. Then where you get this error? From a downloaded script? Yeah, sure.
Btw the "solution" is just make the error gone, but it's not solution for the problem: you have to create a table in database before you can use it. And create it in the mysql connection script is bad, because next time you want to make a script what use database, you'll get this error again, and you'll do the wrong solution... again. And so on.
