Wie wäre es mit so etwas wie
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 = ".$mid."
AND members.status = 7
AND messages.kreaded !='1'
AND messages.subject != 'readed'
ORDER BY messages.fromid ASC,
messages.id DESC
ODER
SELECT DISTINCT messages.fromid,
messages.readed,
messages.fromid,
messages.toid ,
members.id AS pid
FROM messages
INNER JOIN members
ON members.id = messages.fromid
WHERE messages.toid = ".$mid."
AND members.status = 7
AND messages.kreaded !='1'
AND messages.subject != 'readed'
ORDER BY messages.fromid ASC,
messages.sendtime DESC
In messages.fromid ASC der ASC ist rein syntaktisch, da ORDER BY ohne Angabe von ASC/DESC ASC voraussetzt.
SELECT *
FROM TABLE
ORDER BY COL ASC
ist dasselbe wie
SELECT *
FROM TABLE
ORDER BY COL
