Select orders.order_id,order_date ,customer_last_name,shipped_date from customers inner join orders on customer.customer_id = orders.customer_id where orders.employee_id IS NULL order by order_date desc;
14
Select orders.order_id,order_date, first_name || last_name as Employee from orders inner join employees on orders.employee_id = employees.employee_id;
15.
Select orders.order_id,order_date, customer_first_name || customer_last_name as Customer from orders inner join customers on orders.customer_id = customers.customer_id inner join salesrep on salesrep.repid = orders.salesrepid where salesrep.name = 'Thomas Hardy' order by customer_last_name;
