Question

offers.date = CURDATE() 

I what I currently have.

It grabs offers for today, but I also would like to grab the orders for yesterday.

How can I do this, without specifying the yesterday’s date?

Answer 1

To use CURDATE minus or plus a interval (e.g. yesterday) you can use the DATE_ADD function

SELECT DATE_ADD(CURDATE(), INTERVAL -1 DAY);

So, in your case you use it like this:

WHERE offers.date = CURDATE() OR offers.date = DATE_ADD(CURDATE(), INTERVAL -1 DAY)

Optionally you can also use the DATE_SUB() function and instead of a negative interval use the same interval but positive.

Thus, DATE_ADD(CURDATE(), INTERVAL -1 DAY) would become DATE_SUB(CURDATE(), INTERVAL 1 DAY)
