Answer

suggest that if your above SQL statement can query the result. maybe you can just skip the "order by" and simply just

select * from (/* your SQL statement without "order by"*/) a order by a.message_id desc

sorry that as it is difficult to see your screen capture and help you to resolve the SQL script.
