code not running

we should have used the use function first
to select the database that we wanna work on

Hi Peter!
Thanks for reaching out.

Yes, we have to select the database which we would like to use. We can use the following code:
USE db_name; or double-click on the database we would like to use.

Hope this helps.
Best,
Tsvetelin

thanks for this. I was sure I missed a step, I didn't click the sales database first before running the code.
