oracle修改表空間

oracle修改表空間

1、先找到這哪些表的表空間不對

select * from dba_tables where tablespace_name='TDB';

語法是：alter table table_name move tablespace tablespace_name;

alter table tdb2009.ASSOC_INFO move tablespace TDB2009;
alter table tdb2009.BGUSERPOPD move tablespace TDB2009;

alter index PK_WS_ACCESS_LOG_DETAIL rebuild online nologging tablespace rpt03;

將把一個表空間的所有索引換到另一個表空間呢

select 'alter index ' || index_name || ' move tablespace TDB2009;' from user_indexes

select 'alter index TDB2009.'||index_name||' rebuild online nologging tablespace TDB2009;' from user_indexes

語法是：ALTER TABLE 表名 MOVE LOB(lob字段名) STORE AS (TABLESPACE 新表空間名);

ALTER TABLE ws_access_log MOVE LOB(req_content) STORE AS (TABLESPACE rpt03);
ALTER TABLE ws_access_log MOVE LOB(resp_content) STORE AS (TABLESPACE rpt03);

select * from dba_data_files;
select * from dba_lobs where tablespace_name='USERS';
select * from dba_segments where segment_name in('SYS_LOB0000335629C00004$$','SYS_LOB0000335629C00014$$','SYS_LOB0000335635C00006$$','SYS_LOB0000335635C00008$$');
select dbms_metadata.get_ddl('TABLE','WS_ACCESS_LOG','USMM') from dual;
