Instruction

And here's our final table in this set.

Exercise

Select all data from the order_items table.

This is an associative table – it connects data from two tables: orders and products. That's how we know what items form an order.

It consists of the following columns:

  • order_id – the id of the order a given product is part of,
  • product_id – the id of the product itself,
  • quantity – the quantity of the product in this order,
  • price – the total price for the product in this order.
