假設沒有maxvalue部分，那麼加入分割槽:

ALTER TABLE DFMS.WIP_D_WO_DETAIL
ADD PARTITION P201307 VALUES LESS THAN (TO_DATE(' 2013-07-01 00:00:00', 'SYYYY-MM-DD HH24:MI:SS',

NLS_CALENDAR=GREGORIAN'))
    LOGGING
    NOCOMPRESS
    TABLESPACE PART_D_TS1
    PCTFREE    10
    INITRANS   1
    MAXTRANS   255
    STORAGE    (
                INITIAL          50M
                NEXT             50M
                MINEXTENTS       1
                MAXEXTENTS       UNLIMITED
                PCTINCREASE      0
                BUFFER_POOL      DEFAULT
               ) ;

這裡有maxvalue部分，那麼加入分割槽需要split :

備註：
split partition時，根據split point原來的partition分裂成兩個partition。
如果其中一個partition是空的，則不需要move原來的partition，也不需要rebuild
index，這種我們稱之為fast split。

不過如果在split的時候指定了tablespace，即使其中一個partition是空的，而且該
tablespace與parent partition的tablespace不同，oracle會move整個partition到
新的tablespace中。因為這個tablespace引數，導致了原來的fast split不成功，而
需要move segment和rebuild index。

ALTER TABLE DFMS.WIP_D_WO_DETAIL
SPLIT PARTITION PMAX AT (TO_DATE(' 2013-07-01 00:00:00', 'SYYYY-MM-DD HH24:MI:SS', NLS_CALENDAR=GREGORIAN'))
INTO (PARTITION P201307 TABLESPACE PART_D_TS1, PARTITION PMAX TABLESPACE PART_D_TS1) ;

如果你需要取消maxvalue部分，那麼split幾部分後，檢視最後一部分是否有值，如果沒有，直接
drop掉最後split出去的那部分。然後就可以直接add partition 了。

ALTER TABLE DFMS.WIP_D_WO_DETAIL
SPLIT PARTITION PMAX AT (TO_DATE(' 2013-07-01 00:00:00', 'SYYYY-MM-DD HH24:MI:SS', NLS_CALENDAR=GREGORIAN'))
INTO (PARTITION P201307 TABLESPACE PART_D_TS1, PARTITION P2014 TABLESPACE PART_D_TS1) ;

ALTER TABLE DFMS.WIP_D_WO_DETAIL
SPLIT PARTITION P2014 AT (TO_DATE(' 2014-01-01 00:00:00', 'SYYYY-MM-DD HH24:MI:SS', NLS_CALENDAR=GREGORIAN'))
INTO (PARTITION P201401 TABLESPACE PART_D_TS1, PARTITION P201407 TABLESPACE PART_D_TS1) ;

ALTER TABLE DFMS.WIP_D_WO_DETAIL
SPLIT PARTITION P201407 AT (TO_DATE(' 2014-07-01 00:00:00', 'SYYYY-MM-DD HH24:MI:SS', NLS_CALENDAR=GREGORIAN'))
INTO (PARTITION P201407 TABLESPACE PART_D_TS1, PARTITION P201501 TABLESPACE PART_D_TS1) ;

ALTER TABLE DFMS.WIP_D_WO_DETAIL DROP PARTITION P201501 ;

然後就可以類似沒有設定maxvalue一樣加入後面的partiton .

ALTER TABLE DFMS.WIP_D_WO_DETAIL
ADD PARTITION P201501 VALUES LESS THAN (TO_DATE(' 2015-01-01 00:00:00', 'SYYYY-MM-DD HH24:MI:SS',

NLS_CALENDAR=GREGORIAN')) ;

ALTER TABLE DFMS.WIP_D_WO_DETAIL
ADD PARTITION P201507 VALUES LESS THAN (TO_DATE(' 2015-07-01 00:00:00', 'SYYYY-MM-DD HH24:MI:SS',

NLS_CALENDAR=GREGORIAN')) ;

.....

如果在split的時候將tablespace更換了，那麼需要rebuild index .

下面的語句用於rebuild local index partitions或子分割槽
(子分割槽一般指range-hash等組合分割槽中的子分割槽) :
ALTER INDEX ... REBUILD PARTITION/SUBPARTITION

ALTER TABLE ... MODIFY PARTITION/SUBPARTITION ... REBUILD UNUSABLE LOCAL INDEXES
這個語句找出所有的unusable的index, 然後rebuild他們。
