oracle表范围分区的测试例子

-- Create sequence
create sequence SQ1
minvalue 1
maxvalue 999999999999999999999999999
start with 2001
increment by 1
cache 20;

序列的建立

 

create table testpatition
(
Gid number(10,3) primary key,
GName varchar2(36),
GDate date
)
partition by range(Gid) 选择要分区的字段
(
partition p1 values less than(10), 确定分区的范围
partition p2 values less than(20),
partition p3 values less than(30),
partition p4 values less than(300),
partition p5 values less than(600),
partition p6 values less than (maxvalue)最大分区的数据
);

表分区的建立

 

declare
n number:=1;
begin
while n<2000 loop
insert into testpatition(gid,GName,Gdate) values(sq1.nextval,n,sysdate);
n:=n+1;
end loop;
end;

测试数据的添加

 

select * from testpatition partition (p4)

查询分区的数据的例子

select * from testpatition

查询所有的数据
