Select Results on a Rolling Time Period
Hi,
I'm using PHP/MySQL to return data sets on a daily basis.
But what's the WHERE clause statement to extract results from a SELECT query perhaps on a rolling weekly, monthly or quarterly basis?
I'm asking so that the Select query returns a constant moving set of results set based on the data found in the database.

This is the code I was looking for, which produces a 21 rolling day view: -
WHERE invoiceDate >= now() - INTERVAL 21 DAY
WHERE invoiceDate >= now() - INTERVAL 21 DAY

Thanks for the prompt made me realise I knew enough to work it out!

Yes so a typical query might look like: -
SELECT orderID, buyerName, BuyerAddress1, BuyerAddress2, BuyerAddress3, buyerCounty, buyerPCD, catID, quantity, totalPrice FROM salesuk WHERE invoiceDate >= "01/01/2017" ORDER BY DESC;
That type of query ... hope that helps?
