Truy vấn MySQL - vấn đề với thứ tự theo

Còn cái gì đó tương tự thì sao

SELECT DISTINCT messages.fromid, 
            messages.readed, 
            messages.fromid, 
            messages.toid  , 
            members.id AS pid 
FROM            messages 
INNER JOIN members 
ON              members.id = messages.fromid 
WHERE           messages.toid              =  ".$mid." 
AND             members.status             = 7 
AND             messages.kreaded          !='1' 
AND             messages.subject          != 'readed'
ORDER BY    messages.fromid ASC,
            messages.id DESC

HOẶC

SELECT DISTINCT messages.fromid, 
            messages.readed, 
            messages.fromid, 
            messages.toid  , 
            members.id AS pid 
FROM            messages 
INNER JOIN members 
ON              members.id = messages.fromid 
WHERE           messages.toid              =  ".$mid." 
AND             members.status             = 7 
AND             messages.kreaded          !='1' 
AND             messages.subject          != 'readed'
ORDER BY    messages.fromid ASC,
            messages.sendtime DESC

Trong messages.fromid ASC ASC hoàn toàn về mặt cú pháp, như ORDER BY mà không chỉ định ASC / DESC giả định ASC.

SELECT *
FROM TABLE
ORDER BY COL ASC

giống như

SELECT *
FROM TABLE
ORDER BY COL
