如何选择mySQL数据库表的最新条目? [重复]

This question already has an answer here:

I select the latest inserted id from my mySQL database. I also want to select the appropriate name to that latest id.

$pdo = $db->query('SELECT *,MAX(id) AS latest FROM data');
    while ($row = $pdo->fetch(PDO::FETCH_ASSOC)) {
         $id = $row["latest"];
         $name = $row["name"];
    }    

The selecting of the id is working well. But not the latest name is selected, instead always the name of the first row of my table is selected. It doesn't fit to the id

    Why not just

    SELECT name, id FROM data ORDER BY id DESC LIMIT 1
