Question

I have made a simple auction section on my site, and I would like to display the user’s current high bid on their My Bids page. I have a table that holds each unique bid that has the unique auction_id. My current query is as follows, but this only orders the groups instead of ordering what is inside the groups as well. I only want the highest value in each group.

SELECT * 
FROM tblAuctionBids 
WHERE username = '$username' 
GROUP BY auction_id 
ORDER BY id DESC 
LIMIT 10

Answer 1

SELECT MAX(bid), * 
FROM tblAuctionBids 
WHERE username='$username' 
GROUP BY auction_id 
ORDER BY id DESC 
LIMIT 10
