🧐 Question
Hard Find the customer with the most spend 2 JOIN GROUP BY ORDER BY	Solve
Given details of customers, products, and sales, write an SQL query to find the customer with the highest spend. The customer with the highest spend is the one who has spent the most money on purchases. The query should return the full name of the customer and the total amount spent by the customer rounded off to the nearest integer. full_name is the concatenation of first_name and last_name separated by a space. Eg: first_name = 'Alice', last _name = 'Brown' => full_name = 'Alice Brown' You can assume that there will always be non-empty first_name and non-empty last_name entries for all customers in the table.
