Problem Description –
You are running an e-commerce site that is looking for imbalanced orders. An imbalanced order is one whose maximum quantity is strictly greater than the average quantity of every order (including itself).
The average quantity of an order is calculated as
(total quantity of all products in the order) / (number of different products in the order). The maximum quantity of an order is the highest
quantity of any single product in the order.
Write an SQL query to find the
order_id of all imbalanced orders.
Return the result table in any order.
The query result format is in the following example.

with result as ( SELECT order_id, AVG(quantity) as avg_quantity, MAX(quantity) as max_quantity FROM OrdersDetails GROUP BY 1 ) SELECT order_id FROM result WHERE max_quantity > (SELECT MAX(avg_quantity) FROM result)
