-- create table(

建立分割槽表)

create table bill_monthfee_zero

(serv_id             number(20) not null,

billing_cycle_month number(6) not null,

date_type           number(1),

acc_nbr             varchar2(80)

)partition by range (billing_cycle_month)

(partition p_200407 values less than (200407)

tablespace ts_ziken

storage(initial 100k next 100k minextents 1 maxextents unlimited pctincrease 0),

partition p_200408 values less than (200408)

tablespace ts_ziken

storage(initial 100k next 100k minextents 1 maxextents unlimited pctincrease 0))

;create index idx_bill_monthfee_zero_idx01 on bill_monthfee_zero(billing_cycle_month)

tablespace ts_ziken_idx

storage(initial 100k next 100k minextents 1 maxextents unlimited pctincrease 0) nologging;

grant all on bill_monthfee_zero to dxsq_dev;

--增加分割槽表

alter table bill_monthfee_zero add partition p_200409

values less than (200409) tablespace ts_ziken;

--刪除一分割槽

alter table part_tbl drop partition part_tbl_08;

--將乙個分割槽分為兩個分割槽

alter table bill_monthfee_zero split partition p_200409 at (200409)

into (partition p_200409_1 tablespace ts_ziken,

partition p_200409_2 tablespace ts_ziken_idx);

--合併分割槽

altertablebill_monthfee_zero

mergepartitions p_200408

,p_200409intopartitionp_all

--將分割槽改名

altertablebill_monthfee_zero renamepartitionp_200408top_fee_200408

--將分割槽改表空間

altertablebill_monthfee_zero movepartitionp_200409

tablespace ts_ziken_01 nologging

--查詢特定分割槽

select count(*) from bill_monthfee_zero partition (p_200407);

--新增資料

insert into bill_monthfee_zero select * from bill_monthfee_zero partition (p_200407)

--分割槽表的匯出

userid=dxsq/teledoone@jndxsq154

buffer=102400

tables=bill_monthfee:p_200401,

file=e:"exp_para"exp_dxsq_tables.dmp

log=e:"exp_para"exp_dxsq_tables.log

技巧：刪除表中乙個字段：

alter table bill_monthfee_zero set unused column date_type;

新增乙個字段：alter table bill_monthfee_zero add date_type number(1);
