Question

I’m trying to write a query that will find all rows in a group EXCEPT the row with the max value. I have a query so far that finds the row with the max value, but now I need to find all the rest of the rows. Here is a SQLFiddle with the two databases and sample data. I also have the query that finds the max rows.
http://sqlfiddle.com/#!2/514d2/33

For those that don’t want to use SQLFiddle…
Tablename: listings
Tablename: bids

SELECT listings.end_date, listings.user_id, listings.title, 
  listings.auc_fp, listings.id, listings.auc_image1
FROM listings 
JOIN bids b1 
ON b1.listing_id=listings.id 
LEFT JOIN bids b2 
ON b2.listing_id=listings.id AND b1.bid < b2.bid
WHERE b1.user_id = 1
AND b2.bid IS NULL
AND listings.end_date > NOW()
ORDER BY listings.list_ts DESC

Above is the query that find the max rows. I’m trying to join the listings table with the bids table on listings.id=bids.listing_id. Then I need to find all the rows where a user ($user or user “1”) has bid on that listing. Then I need to exclude the listings where the user is has the max bid (which is what the query above does).

I originally thought I could use the query above as a subquery to exclude the listings where the user is the max bidder. But I’m not sure if that’s the best way to do it and I’m not that good with subqueries.

Note that answer was revised several times based on the comments below.

SELECT
    lst.end_date,
    lst.title,
    lst.auc_fp,
    lst.id as listing_id,
    lst.auc_image1,
    b.user_id as bid_user_id,
    b.bid as bid_amount,
    maxbids.maxbid as maxbid_for_listing
FROM listings lst
INNER JOIN
(
    SELECT listing_id, MAX(bid) maxbid
    FROM bids b
    GROUP BY listing_id
) maxbids ON lst.id = maxbids.listing_id
INNER JOIN bids maxusers ON maxusers.bid = maxbids.maxbid AND maxusers.listing_id = maxbids.listing_id
INNER JOIN bids b ON
    maxbids.listing_id = b.listing_Id AND
    b.bid < maxbids.maxbid AND
    b.user_id <> maxusers.user_id
WHERE lst.end_date > NOW()
ORDER BY lst.list_ts DESC
