自动为分区表增加分区存储过程：

Sql代码

create or replace procedure guan_add_partition

/*为一个用户下所有分区表自动增加分区.分区的列为date类型,分区名类似:p200706.

/*create by David

v_table_name varchar2(50);

v_partition_name varchar2(50);

v_month char(6);

v_add_month_1 char(6);

v_sql_string varchar2(2000);

v_add_month varchar2(20);

cursor cur_part is select distinct u.table_name,max(p.partition_name) max_part_name from user_tables u,user_tab_partitions p

where u.table_name=p.table_name and u.partitioned = 'YES'

group by u.table_name;

Begin

select to_char(sysdate,'yyyymm') into v_month from dual;

select to_char(add_months(sysdate,1),'yyyymm') into v_add_month_1 from dual;

select to_char(add_months(trunc(sysdate,'mm'),2),'yyyy-mm-dd') into v_add_month from dual;

open cur_part;

loop

fetch cur_part into v_table_name,v_partition_name;

exit when cur_part%notfound; www.2cto.com

if to_number(substr(v_partition_name,2)) <=to_number(substr(v_month,1)) then

v_sql_string :='alter table '||v_table_name||' add partition p'||v_add_month_1||

' VALUES LESS THAN ( to_date('''||v_add_month||''',''yyyy-mm-dd'') ) ';

execute immediate v_sql_string;

else

null;

end if;

end loop;

close cur_part;

end;

oracle job脚本：

Sql代码

begin

sys.dbms_job.submit(job => :job,

what => 'guan_add_partition;',

next_date => to_date('02-04-2012', 'dd-mm-yyyy'),

interval => 'trunc(sysdate)+1');

commit;

end;
