Answer 1

你可以这样做：

SELECT * FROM(
    SELECT distinct id as 1st
    FROM YourTable
    WHERE 1st =(select max(1st)
                FROM YourTable))
INNER JOIN
    (SELECT distinct id as 2nd
    FROM YourTable
    WHERE 2nd =(select max(2nd)
                FROM YourTable))
ON(1=1)  

这仅适用于每列中有1个MAX值的情况。
