截断分割log表的存储过程log_history:
create or replace procedure log_history
is
query_str varchar2(32767);
year_month 	varchar2(8);
times	number;
begin
select to_char(sysdate-15,'YYYYMMDD') into year_month from dual;
times:=0;
query_str :='create table log_new pctfree 10 pctused 80
as select * from log where 1=2';
execute immediate query_str;
query_str :='alter table log_new add constraints log_'
 ||year_month||'_pk
