oracle查詢某個用戶下的全部數據表的表名和大小
select a.segment_name,a.segment_type,a.bytes,a.bytes / 1024 / 1024 byte_m,b.created
from dba_segments a
inner join all_objects b on b.object_type = 'TABLE' and a.owner = b.owner and a.segment_name = b.object_name
where a.owner = 'USER' and a.segment_type = 'TABLE' /* and a.bytes>50000000*/
order by a.bytes desc;
a.owner后面跟想查詢的用戶名，查詢沒數據，可以試下a.owner = upper('USER')
