Oracle分区之四：分区维护和管理

 一，分区表的相关实验
创建一个列表分区表
create table t3(id number,city varchar2(10))
partition by list(city)
(
partition p1 values ('SH','JS','ZJ') ,
partition p2 values ('BJ','TJ','HB') ,
partition p3 values ('GZ','SZ') ,
partition p_others values (default)
);
create or replace procedure proc1
as
begin
for i in 1..1000
loop
execute immediate
'INSERT INTO T3 values(:x,:y)' USING i,'SH';
end loop;
end;
/
exec proc1
create or replace procedure proc1
as
begin
for i in 1001..2000
loop
execute immediate
'INSERT INTO T3 values(:x,:y)' USING i,'JS';
end loop;
end;
/
exec proc1
create or replace procedure proc1
as
begin
for i in 2001..3000
loop
execute immediate
'INSERT INTO T3 values(:x,:y)' USING i,'ZJ';
end loop;
end;
/
exec proc1
create or replace procedure proc1
as
begin
for i in 3001..4000
loop
execute immediate
'INSERT INTO T3 values(:x,:y)' USING i,'BJ';
end loop;
end;
/
exec proc1
create or replace procedure proc1
as
begin
for i in 4001..5000
loop
execute immediate
'INSERT INTO T3 values(:x,:y)' USING i,'TJ';
end loop;
end;
/
exec proc1
create or replace procedure proc1
as
begin
for i in 5001..6000
loop
execute immediate
'INSERT INTO T3 values(:x,:y)' USING i,'GZ';
end loop;
end;
/
exec proc1
create or replace procedure proc1
as
begin
for i in 6001..7000
loop
execute immediate
'INSERT INTO T3 values(:x,:y)' USING i,'HB';
end loop;
end;
/
exec proc1
create or replace procedure proc1
as
begin
for i in 7001..8000
loop
execute immediate
'INSERT INTO T3 values(:x,:y)' USING i,'SZ';
end loop;
end;
/
exec proc1
create or replace procedure proc1
as
begin
for i in 8001..10000
loop
execute immediate
'INSERT INTO T3 values(:x,:y)' USING i,'AH';
end loop;
end;
/
exec proc1
