Write a solution to find the percentage of immediate orders in the first orders of all customers, rounded to 2 decimal places.
Return the result table in any order.
I have solved this question using row_number(). The ROW_NUMBER() is a window function that assigns a sequential integer number to each row in the query's result set.
The runtime of my solution beats 99.96% of the users and memory beats 100% of the users.
