1.修改分区表分区表空间

SELECT    'ALTER TABLE '
       || table_owner
       || '.'
       || TABLE_NAME
       || ' MOVE PARTITION '
       || PARTITION_NAME
       || ' TABLESPACE D_TBS_NEW;'
  FROM DBA_TAB_PARTITIONS
 WHERE TABLE_OWNER = 'OWNER' AND TABLE_NAME IN ('TABLE_NAMES')

ALTER TABLE OWNER.TABLENAME MOVE PARTITION PAT_P201906 TABLESPACE D_TBS_NEW;

2.修改分区表默认表空间

分区表的默认表空间即表定义里面的tablespace，不是分区定义里面的tablespace。如果表为自动分区，那么新分区会直接建到默认表空间里面

SELECT    'alter table '
       || owner
       || '.'
       || table_name
       || ' modify default attributes tablespace D_TBS_NEW;'
  FROM DBA_TABLES
 WHERE OWNER = 'OWNER' AND TABLE_NAME IN ('TABLE_NAME')

alter table OWNER.TABLENAME modify default attributes tablespace D_TBS_NEW;

3.修改分表索引分区表空间

SELECT    'ALTER INDEX '
       || index_owner
       || '.'
       || index_name
       || ' REBUILD PARTITION '
       || PARTITION_NAME
       || ' TABLESPACE D_TBS_NEW;'
  FROM DBA_ind_PARTITIONS
 WHERE index_owner = 'OWNER' AND INDEX_NAME LIKE  '%TABLENAME%'

ALTER INDEX OWNER.INDEXNAME REBUILD PARTITION PAT_P201906 TABLESPACE D_TBS_NEW;

4.修改普通索引表空间

SELECT    'ALTER INDEX '
       || owner
       || '.'
       || index_name
       || ' REBUILD  TABLESPACE I_TBS_NEW;'
  FROM dba_indexes
 WHERE owner = 'OWNER' AND table_name IN ('TABLE_NAME')

ALTER INDEX OWNER.INDEXNAME REBUILD  TABLESPACE I_TBS_NEW;

--这里面可能会包含分区索引，执行的时候会报错，忽略即可

5.修改分区索引默认表空间

SELECT    'ALTER INDEX '
       || owner
       || '.'
       || index_name
       || ' modify default attributes tablespace I_TBS_NEW;'
  FROM dba_indexes
 WHERE OWNER = 'OWNER' AND table_name in ('TABLE_NAMES')

 alter index OWNER.INDEXNAME modify default attributes tablespace I_TBS_NEW;

--这里面可能包含普通索引，执行会报错，忽略即可
