MySQL GROUP BY Sorting Guide

In MySQL, you can group data by specific columns using the GROUP BY clause, and then sort the data within each group using the ORDER BY clause.

For instance, let’s say we have a table called “orders” that includes information about orders, such as order number (order_id), customer number (customer_id), and order amount (order_amount).

To group by customer number and sort each group in descending order by order amount, you can use the following query:

SELECT customer_id, SUM(order_amount) AS total_amount
FROM orders
GROUP BY customer_id
ORDER BY total_amount DESC;

This query first groups the customer_id using the GROUP BY clause, then calculates the total order amount for each group using the SUM function and names it “total_amount”. Finally, it sorts the results in descending order using the ORDER BY clause based on total_amount.

Please modify the table name, column names, and sorting method to suit your specific needs.
