Oracle 创建分区表

 -----创建表空间
 create tablespace myTableSpace_1 datafile 'C:/oracle/product/10.1.0/oradata/mydata/myTableSpace1.dbf'
 size 100m extent management local uniform size 256K
 
  create tablespace myTableSpace_2 datafile 'C:/oracle/product/10.1.0/oradata/mydata/myTableSpace2.dbf'
 size 100m extent management local uniform size 256K
 
   create tablespace myTableSpace_3 datafile 'C:/oracle/product/10.1.0/oradata/mydata/myTableSpace3.dbf'
 size 100m extent management local uniform size 256K
 
 
 -----创建分区
 create table MyTest
 (
        id number,
        name nvarchar2(100)
 )
 partition by range(id)
 (
  partition T1 values less than (100) tablespace myTableSpace_1,
  partition T2 values less than (1000) tablespace myTableSpace_2,
  partition T3 values less than (maxvalue) tablespace myTableSpace_3)

-----设置表可以修改
alter table mytest2 enable row movement;
 
  -----给分区表插入数据
 
  insert into MyTest values (10,'f1111');
  insert into MyTest values (20,'f1112');
  insert into MyTest values (100,'f1112');
  insert into MyTest values (200,'f1112');
  insert into MyTest values (1001,'f1112');
  commit;
 
 ------查询分区表
  select * from MyTest
 
  select * from myTest partition(T1);
  select * from myTest partition(T2);
  select * from myTest partition(T3);
 
  ------删除一个有表分区，同时些表分区的数据也将删除
  ALTER TABLE myTest DROP PARTITION T3;
  ------  插入一个表分区，插入时必须是在最大的表分区住下插入
  alter table myTest add partition T3 values less than (10000) tablespace myTableSpace_3;
