Building a detailed invoice
In the store schema, you have the invoice, invoiceline, and track table. However, these don't quite stand on their own. To get a better idea of customer behavior, we're going to "recreate" each of these invoices with a bit more detail. We'll do this using two common table expressions, which you'll build from the ground up.
