dsamarin / all-orders-placed-by-a-customer.sql
Created October 9, 2019 08:31 — forked from dan81989/all-orders-placed-by-a-customer
Let’s say we want to find all orders placed by a particular customer. We can do this by joining the customers and orders tables together using the relationship established by the customer_id key.
SELECT order_date, order_amount
FROM customers
JOIN orders
ON customers.customer_id = orders.customer_id
WHERE customer_id = 3
