Mysql/php SELECT ORDER BY

Question

I have a select like:

SELECT * FROM xxx WHERE id = 5 ORDER BY id DESC

But I need to order my select with the "Name" column that is into another Table... How can I do ?

Answer 1

SELECT  xxx.*, yyy.name
FROM    xxx
JOIN    yyy
ON      yyy.x_id = xxx.id
WHERE   xxx.id = 5
ORDER BY
        yyy.name DESC

Answer 2

我相信这是朝着正确的方向前进：

SELECT * from xxx LEFT JOIN yyy ON yyy.name = xxx.whateverkey WHERE id = 5 ORDER BY yyy.name DESC
