MySQL Query - How to Get Data From Current Month and Same Month Last Year?
I have a simple query that sums sales totals for September and compares them with Sept of last year. How can I write this so that it auto updates with the current month month each month?
This is part of a PHP script so if there's a better/easier way to do it in PHP I'd be happy to hear about that as well.
Thank You!
Select Salesman,
SUM(CASE WHEN InvoiceDate Between '2015-9-1' and '2015-9-30' THEN Totsales else 0 end) as Sales15,
SUM(CASE WHEN InvoiceDate Between '2016-9-1' and '2016-9-30' THEN Totsales else 0 end) as Sales16

You could use a query where you select just by year and month instead of using between starts and stop. This way you could pass as parameter a comparing date like CURRENT_DATE. The query could be explained so: select the sum for any date with the same month and year of today and the sum for any date with the same month of today but 1 year less.
Take a look at the query
If you need you could replace the CURRENT_DATE value with any other date by php and pass it to the query by code

SELECT Salesman,
SUM(CASE WHEN (MONTH(InvoiceDate) = MONTH( CURRENT_DATE ) AND YEAR(InvoiceDate) = YEAR( CURRENT_DATE ) ) THEN Totsales ELSE 0 END) AS Sales16,
SUM(CASE WHEN (MONTH(InvoiceDate) = MONTH( CURRENT_DATE ) AND YEAR(InvoiceDate) = YEAR( CURRENT_DATE - INTERVAL 1 YEAR ) ) THEN Totsales ELSE 0 END) AS Sales15

I think this is what you asked for - not sure it is what you want. For this to mean anything it would need to run on the last day of the month. Otherwise if you want to look back at the last month it would require some tweaking.
SELECT Salesman,
SUM(CASE WHEN InvoiceDate BETWEEN CONCAT(YEAR(NOW())-1, '-', MONTH(NOW()), '-01') AND CONCAT(YEAR(NOW())-1, '-', MONTH(NOW()), '-', DAY(LAST_DAY(NOW()))) THEN Totsales ELSE 0 END) AS Sales15,
SUM(CASE WHEN InvoiceDate BETWEEN CONCAT(YEAR(NOW()), '-', MONTH(NOW()), '-01') AND CONCAT(YEAR(NOW()), '-', MONTH(NOW()), '-', DAY(LAST_DAY(NOW()))) THEN Totsales ELSE 0 END) AS Sales16
