1，查詢

PMMSTKNWIP;select * from PMMSTKNWIP

2，分割分區

ALTER TABLE PMMSTKNWIP SPLIT PARTITION P2011
AT('20120101')
INTO (PARTITION P2011,PARTITION P2012);

ALTER TABLE PMMSTKNWIP SPLIT PARTITION P2012
AT('20130101')
INTO (PARTITION P2012,PARTITION P2013);

3，刪除分區，同時刪除數據

ALTER TABLE PMMSTKNWIP drop  PARTITION P2010;
ALTER TABLE PMMSTKNWIP drop  PARTITION P2011;

4，刪除索引

ALTER TABLE PMMSTKNWIP
MODIFY PRIMARY KEY disable;------對主鍵
 drop index PK_MSTKNWI ;
-- Create/Recreate indexes
drop index IDX_0002;
drop index IDX_0006;
drop index IDX_0007 ;
drop index IDX_001 ;
drop index IDX_003 ;
drop index IDX_004 ;
drop index IDX_COMBINE ;
drop index INDEX_CONFDATE ;
drop index INDEX_PN ;

5，重建索引
ALTER TABLE PMMSTKNWIP
MODIFY PRIMARY KEY enable------主鍵

-- Create/Recreate indexes
