思路
1.首先移动子分区到别的表空间。
2.收缩数据文件。
3.再把子分区移回原表空间。
---------------------------------------------生成发送报告移动子分区语句---------------------------------------------
select 'alter table '||TABLE_NAME||' move subpartition '||SUBPARTITION_NAME||' tablespace SMART_NRRPSTA01;' from dba_tab_subpartitions
where table_name = 'S_T_RTNRP_STATUS'
AND PARTITION_NAME LIKE 'ST_RRPS_12%'
ORDER BY SUBPARTITION_NAME
select 'alter table '||TABLE_NAME||' move subpartition '||SUBPARTITION_NAME||' tablespace SMART_NSNRP01;' from dba_tab_subpartitions
where table_name = 'S_T_SEND_REPORT'
AND PARTITION_NAME LIKE 'ST_SNDRP_12%'
ORDER BY SUBPARTITION_NAME
--------------------------------------------生成返回报告移动子分区语句---------------------------------------------
select 'alter table '||TABLE_NAME||' move subpartition '||SUBPARTITION_NAME||' tablespace SMART;' from dba_tab_subpartitions
where table_name = 'S_T_RTNRP_STATUS'
AND PARTITION_NAME LIKE 'ST_RRPS_01%'
ORDER BY SUBPARTITION_NAME
select 'alter table '||TABLE_NAME||' move subpartition '||SUBPARTITION_NAME||' tablespace SMART_NRRPSTA01;' from dba_tab_subpartitions
where table_name = 'S_T_RTNRP_STATUS'
AND PARTITION_NAME LIKE 'ST_RRPS_01%'
ORDER BY SUBPARTITION_NAME
--------------------------------查看数据文件号---------------------------------------
select TABLESPACE_NAME,FILE_ID,FILE_NAME FROM DBA_DATA_FILES
WHERE TABLESPACE_NAME = 'SMART_NSNRP01'
select TABLESPACE_NAME,FILE_ID,FILE_NAME FROM DBA_DATA_FILES
WHERE TABLESPACE_NAME = 'SMART_NRRPSTA01'
--------------------------------查看数据块最大id值---------------------------------
show parameter db_block_size 查看db_block_size的值
select TABLESPACE_NAME,file_id,max(block_id),max(block_id)*16/1024 from dba_extents where file_id in(99,100,101)
group by TABLESPACE_NAME,file_id
--------------------------------回收发送报告数据文件空间----------------------------------------
