Gregory,
This will give you the number of extents allocated and the the last used
block# for a given segment.
select extent_id+1, block_id
from dba_extents
where extent_id = (select max(extent_id)
from dba_extents
where segment_name = 'YYY'
and owner = 'XXX'
and tablespace_name = 'ZZZ')
and segment_name = 'YYY'
and owner = 'XXX'
and tablespace_name = 'ZZZ';
So the total space used (in bytes) = # of extents * extent size * block size

I need to determine how much space some tables/indexes are really
using, as opposed to how much is allocated to them. Anyone have a
script you'd be willing to share?
Cheers!
