Hrm, fix the application?
You might be able to make a go out of something along the lines of
select ev_id,... from (select * from clients_event_log limit 100) as ss;
which would admit an ORDER BY on the end.
BTW, in most cases it doesn't make any sense to have a LIMIT without an
ORDER BY inside the subselect --- unless you really don't care which 100
rows you get.
