1. 查詢表空間中表對應的大小，好確定對哪張表進行操作
select * from dba_segments where tablespace_name='tbs_s05 ' and segment_type in ('table','table partition');
2. 允許表進行行移動 (某些表不能進行truncate，只能delete)
alter table tbl_etcgantrypicwaste enable row movement;
3. 對錶進行高水位線**
--普通表
alter table tbl_etcgantrypicwaste shrink space cascade;
--分割槽表
alter table tbl_etcgantrypicwaste modify partition sys886 shrink space cascade;
4. 取消錶行移動
alter table tbl_etcgantrypicwaste disable row movement;
5. 更新統計資訊
analyze table tbl_etcgantrypicwaste compute statistics;
