PHP/MYSQL Compare Date this month and last Month

Question

I am working on a report module. I have worked on comparing this week and last weeks report for certain agents.

This weeks Report query is as follows

SELECT COUNT(created_at) AS cust_count_new, agency_id, created_at FROM customers WHERE 
(customers.created_at >= DATE(NOW()) - INTERVAL 6 DAY AND customers.created_at
< DATE(NOW()) + INTERVAL 1 DAY

Last Week Report query is as follows

SELECT COUNT(created_at) AS cust_count_old, agency_id, created_at FROM customers WHERE 
(customers.created_at >= DATE(NOW()) - INTERVAL 13 DAY AND customers.created_at 
< DATE(NOW()) - INTERVAL 6 DAY

What I am doing is comparing this weeks and last weeks report. Now how can i change the query to this month and last months (30 days). I am little confused, so any help is appreciated.

Answer 1

You can use MONTH as unit in the INTERVAL . Also, you can use CURDATE() instead of DATE(NOW()) , to get the current date.

This Month Report query will be:

SELECT COUNT(created_at) AS cust_count_new, 
       agency_id, 
       created_at 
FROM customers 
WHERE customers.created_at >= CURDATE() - INTERVAL 1 MONTH AND 
customers.created_at < CURDATE() + INTERVAL 1 DAY

Last Month Report query is as follows

SELECT COUNT(created_at) AS cust_count_new, 
       agency_id, 
       created_at 
FROM customers 
WHERE customers.created_at >= CURDATE() - INTERVAL 2 MONTH AND 
customers.created_at < (CURDATE() - INTERVAL 1 MONTH) + INTERVAL 1 DAY
