1) EXPDP\IMPDP
採用邏輯匯出匯入很簡單，首先在源庫建立分割槽表，然後將資料匯出，然後匯入到新建的分割槽表即可

2) Insert into
利用原表重建分割槽表,再insert into 分割槽表 select *　from 原表

3) Exchange Partition(交換分割槽)

4) DBMS_REDEFINITION(線上重定義)

簡單介紹1、2兩種的實驗過程
普通表資料如下
conn hr/hr
SQL> select * from CUSTOMER99;
CUST_NAME CUST_ID
---------------------------------------- ----------
1 1
11 11
21 21
31 31
41 41

--Insert into的案例
SQL>CREATE TABLE customer199
( cust_name varchar2(20)
, cust_id NUMBER
)
PARTITION BY RANGE (cust_id)
( PARTITION q1t VALUES LESS THAN (10)
, PARTITION q2t VALUES LESS THAN (20)
, PARTITION q3t VALUES LESS THAN (30)
, PARTITION q4t VALUES LESS THAN (40)
, partition q5t VALUES LESS THAN(maxvalue)
);

SQL>insert into customer199 select * from CUSTOMER99;

SQL> select * from customer199 partition(q3t);
CUST_NAME CUST_ID
---------------------------------------- ----------
21 21

--EXPDP\IMPDP的案例
expdp hr/hr directory=DATA_PUMP_DIR dumpfile=CUSTOMER99.dmp tables=CUSTOMER99
CREATE TABLE customer_expdp
( cust_name varchar2(20)
, cust_id NUMBER
)
PARTITION BY RANGE (cust_id)
( PARTITION q11 VALUES LESS THAN (10)
, PARTITION q21 VALUES LESS THAN (20)
, PARTITION q31 VALUES LESS THAN (30)
, PARTITION q41 VALUES LESS THAN (40)
, partition q51 VALUES LESS THAN(maxvalue)
);
impdp hr/hr directory=DATA_PUMP_DIR dumpfile=CUSTOMER99.dmp remap_table=CUSTOMER99:customer_expdp table_exists_action=append
SQL> select * from customer_expdp partition(q31);
CUST_NAME CUST_ID
---------------------------------------- ----------
21 21
