Very lost. This is the prompt:
In an ecommerce database there's an orders table with the columns id, product_id, user_id, address_id, ordered_on, status and cost. Count the total number of orders that were ordered yesterday and have the status of 'shipped'. Alias it to ordered_yesterday_and_shipped.

- use the "COUNT" function
- give the column the correct alias name
- filter (using "WHERE") both the status AND the date
- you can represent "yesterday" by "
date("now", "-1 day")
"
Give it your best shot, and if you still have trouble, show your query code for more specific help.

This was my response and I am getting an error they they were "expecting a count of 14."
Any suggestions?

And Fairooz — were you able to solve this challenge yourself?
