Question: Could you tell me the name of the customer that made the order that had the largest quantity of items in it?
SQL: SELECT t1.customer_name FROM customers AS t1 JOIN customer_orders AS t2 ON t1.customer_id   =   t2.customer_id JOIN order_items AS t3 ON t2.order_id   =   t3.order_id WHERE t3.order_quantity   =    (  SELECT max ( order_quantity )  FROM order_items )
