select owner, object_name, subobject_name, nb_writes
from ( select owner, object_name, subobject_name,
sum(value) nb_writes,
rank() over (order by sum(value) desc) rk
from v$segment_statistics
where statistic_name like 'physical writes%'
and owner != 'SYS'
group by owner, object_name, subobject_name
having sum(value) > 0 )
where rk <= 50
order by rk
/
Regards
Michel
