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

Here you go, use this to get the date between the 1st of last month and the last of last month in MySQL:

... order_placed_date BETWEEN DATE_FORMAT(NOW() - INTERVAL 1 MONTH, '%Y-%m-01 00:00:00')
AND DATE_FORMAT(LAST_DAY(NOW() - INTERVAL 1 MONTH), '%Y-%m-%d 23:59:59')
