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; /?
