How to order by with group by in mysql

One way to do this is with a bunch of while loops and hitting the DB over and over, or selecting a crap load of data and just dropping out everything but the most recent inventory count manually. Both of these are viable solutions with a lot of overhead, but what I really want is just a silver bullet SQL statement that does this for me. I think I have it.

What I initially envisioned was:

SELECT *
FROM INVENTORY
ORDER BY vendors_no,
timestamp DESC
GROUP BY vendors_no,
product_no

Select ‘edit profile’ from your PayPal account and check the following settings.

• Under ‘Selling Preferences’ >> ‘Instant Payment Notification Preferences’
  • Set the IPN value to ‘On’
  • Set the IPN URL to the PHP page containing the IPN code shown in steps 3 & 4 of this tutorial. (http://www.example.com/payment.php)
• Under ‘Selling Preferences’ >> ‘payment receiving preferences’
  • Block payments from users who pay with echeck. (This is because these will not be instant payments)
• Under ‘account information’ >> ‘email’
  • Note down your primary email address. This email will be visible to users so make it a professional one. User’s may feel apprehensive about sending money to an e-mail address with the domain ‘hotmail.com’ or ‘Yahoo.com’ etc…
