Group-wise Maximum of a Certain Column

Question

I\'ve got the table:

SELECT * FROM shop;

+---------+--------+------
| article | dealer | price
+---------+--------+------
|    0001 | A      |  3.45
|    00         


        

Answer 1

Here you go:

SELECT article, dealer, price
FROM (SELECT article, dealer, price
      FROM shop
      ORDER BY price DESC) AS h
GROUP BY article

This solution doesn't even require a MAX() function. :)

Note: This solution doesn't work with ONLY_FULL_GROUP_BY active and only works in MySQL. This solution is to a certain extent unsupported due to lack of documentation confirming this behavior. It works well for me and has always worked well for me however.

This method still works on the latest MySQL on sqlfiddle.
