My version. Show Oracle DB uptime in format DDd HHh MMm SSs

select to_char(trunc((((86400*x)/60)/60)/24)) || 'd ' ||
   to_char(trunc(((86400*x)/60)/60)-24*(trunc((((86400*x)/60)/60)/24)), 'FM00') || 'h ' ||
   to_char(trunc((86400*x)/60)-60*(trunc(((86400*x)/60)/60)), 'FM00') || 'm ' ||
   to_char(trunc(86400*x)-60*(trunc((86400*x)/60)), 'FM00') || 's' "UPTIME"
 from (select (sysdate - t.startup_time) x from V$INSTANCE t);
