select segment_name, sum(bytes)/1024/1024 Mbytese from user_segments group by segment_name;

1、表佔用空間：

select segment_name, sum(bytes)/1024/1024 Mbytese from user_segments where segment_type='TABLE' group by segment_name;

2、索引佔用空間：

select segment_name ,sum(bytes)/1024/1024 from user_segments where segment_type ='INDEX' group by segment_name;

3、分區表TABLE PARTITION佔用空間：

select segment_name,sum(bytes)/1024/1024 Mbytes from user_segments where segment_type='TABLE PARTITION' group by segment_name;
