SELECT COUNT(*) FROM orders WHERE status = 'shipped' AND DATE('now', '-1 day');

The lines you quoted above include: "Alias it to shipped_yesterday". You still need to apply that alias to the count.
Also, the last part of your WHERE clause seems incomplete. You probably meant to compare that calculated date to one of the table columns.

9,921 PointsIn 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 have the status of shipped yesterday. Alias it to shipped_yesterday
