--把kingstar.emp表的数据迁移到kingstar.EMP_partition分区表中
--创建数据源表结构
| drop table kingstar.emp; create table kingstar.emp as select * from scott.emp where 1=2; alter table kingstar.EMP add constraint PK_EMP primary key (EMPNO) using index tablespace USERS pctfree 10 initrans 2 maxtrans 255 storage ( initial 64K minextents 1 maxextents unlimited ); truncate table kingstar.emp; |
--插入数据
| insert into kingstar.emp values (1,' 蔡浪','D',0,to_date('20080801 12:22:13','yyyymmdd hh24:mi:ss'),1000,1000,10); insert into kingstar.emp values (2,' 蔡星','D',1,to_date('20080901 13:23:12','yyyymmdd hh24:mi:ss'),5000,5000,10); commit; |
--查看迁移表中的数据
| select * from kingstar.emp; 1 1 蔡浪 D 0 2008-8-1 12:22:13 1000.00 1000.00 10 2 2 蔡星 D 1 2008-9-1 13:23:12 5000.00 5000.00 10 |
--创建分区表 结构与kingstar.emp一样
-- Create table
| create table kingstar.EMP_partition ( EMPNO NUMBER(4), ENAME VARCHAR2(10), JOB VARCHAR2(9), MGR NUMBER(4), HIREDATE DATE, SAL NUMBER(7,2), COMM NUMBER(7,2), DEPTNO NUMBER(2) ) tablespace KINGSTAR partition by range(hiredate) (partition emp_max values less than(maxvalue))--由于交换数据时需指定分区，所以这里不做详细分区，数据交换完后进行分区的拆分 ; |
