Hi MG,
Thanks for the query.
1 more...
which is the efficient query to execute on a prod db:
select segment_name, round(sum(bytes)/1024/1024/1024) from dba_segments
group by segment_name
having round(sum(bytes)/1024/1024/1024) >1;
select segment_name, sum(bytes) from dba_segments
group by segment_name
having sum(bytes)>1048576*1024 ;
Tx and Regards,
Srinivas
