自动为分区表增加分区存储过程

自动为分区表增加分区存储过程：

 

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
*/
as
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;
      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：

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;
