SQLQuokkaSQLQuokkaOnboarding cohort analyses need to examine each customer's initial purchase on Amazon. Write a SQL query to return each customer's first order details: `customer_id`, `order_id`, `order_date`, and `order_amount`. If a customer placed multiple orders on their earliest date, break ties deterministically by selecting the order with the smallest `order_id`. Order the final results by `customer_id ASC`. Note: Window function support requires DuckDB / full SQL engine capabilities. This question is staged for the upcoming DuckDB browser engine.
