Probably not, because I don't think he wants the other statuses to have special ranking over the others, so a status=4 and status=1 row should be sorted by lastreply only effectively. This is the problem of combining separate status flags into a single field if you want to be doing these sorts of queries. ---------------------------(end of broadcast)--------------------------- TIP 2: you can get off all lists at once with the unregister command (send "unregister YourEmailAddressHere" to [EMAIL PROTECTED])
