MySQL Query to calculate the Previous Month

Question

I would like to calculate total order amount in the previous month.

I got the query for getting the data for the present month from the current date.

Answer 1

Simplest solution:

SELECT SUM(goods_total) AS Total_Amount FROM orders
WHERE YEAR(order_placed_date) = YEAR(CURDATE() - INTERVAL 1 MONTH)
AND MONTH(order_placed_date) = MONTH(CURDATE() - INTERVAL 1 MONTH)
