Get MAX from a GROUP BY

Question

I was practicing some SQL when this hit me. I wanted to see how many times a certain commodity came up and from there get the commodity which came up the most.

Answer 1

CAUTION: the query will not handle duplicate records having the maximum COUNT

SELECT  commodity,  COUNT(commodity) `count` 
FROM    orders 
GROUP   BY commodity
ORDER   BY `count` DESC 
LIMIT   1

But this will,

SELECT  commodity,  COUNT(commodity) `count` 
FROM    orders 
GROUP   BY commodity
HAVING  COUNT(commodity) =
(
    SELECT MAX(`COUNT`) 
    FROM
    (
        SELECT  COUNT(commodity) `count` 
        FROM    orders 
        GROUP   BY commodity
    )   s
)
