Summary

Instruction

Great! The second table is named delivery; it will be used in our exercises. It is used by a supermarket to keep track of all deliveries.

The table has the following columns:

  • supplier (the company that delivers the products).
  • category (such as Toys or Office).
  • delivery_date (when the products were delivered to the store).
  • total_price (how much was paid for the whole delivery).

Exercise

Select all information from the delivery table.
