Please compare the frequency of the customer details using a bar chart, and I want to show x-axis in desc order.
SELECT customer_details, COUNT(customer_details) FROM Customers GROUP BY customer_details ORDER BY customer_details DESC
SELECT "customer_details", COUNT("customer_details") FROM "Customers" GROUP BY "customer_details" ORDER BY "customer_details" DESC
