job

1:每分钟执行

Interval => TRUNC(sysdate,'mi') + 1/ (24*60)

或

Interval => sysdate+1/1440

2:每天定时执行

例如：每天的凌晨1点执行

Interval => TRUNC(sysdate) + 1 +1/ (24)

3:每周定时执行

例如：每周一凌晨1点执行

Interval => TRUNC(next_day(sysdate,'星期一'))+1/24

4:每月定时执行

例如：每月1日凌晨1点执行

Interval =>TRUNC(LAST_DAY(SYSDATE))+1+1/24

5:每季度定时执行

例如每季度的第一天凌晨1点执行

Interval => TRUNC(ADD_MONTHS(SYSDATE,3),'Q') + 1/24

6:每半年定时执行

例如：每年7月1日和1月1日凌晨1点

Interval => ADD_MONTHS(trunc(sysdate,'yyyy'),6)+1/24

7:每年定时执行

例如：每年1月1日凌晨1点执行

Interval =>ADD_MONTHS(trunc(sysdate,'yyyy'),12)+1/24

--创建一个job,这个job在创建的时候已经被运行

                      next_date => sysdate,       --第一次执行时间
                      interval => 'sysdate+1/1440');--执行间隔
  commit;
end;
/

--查看创建的JOB
select * from sys.user_jobs;

--执行job
begin
   dbms_job.run(:job);       
end;

--停止JOB

1.创建序列

CREATE SEQUENCE hpcms_case_number
INCREMENT BY 1 -- 每次加几个
START WITH 1 -- 从1开始计数
NOMAXvalue -- 不设置最大值
NOCYCLE -- 一直累加，不循环
noCACHE ;
2.查看序列
select case_notes_number.currval from dual ;
select case_notes_number.nextval from dual ;

 

3.创建重置序列的存储过程

create or replace procedure reset_seq as
  n_temp number(30);
  s_tsql varchar2(100);
begin
  execute immediate ' select hpcms_case_number.nextval from dual' into n_temp;

  if n_temp <> 1 then
    n_temp := - (n_temp - 1);
    s_tsql := ' alter sequence hpcms_case_number increment by ' || n_temp;
    execute immediate s_tsql;
    execute immediate ' select hpcms_case_number.nextval from dual' into n_temp;
    s_tsql := ' alter sequence hpcms_case_number increment by 1 ';
    execute immediate s_tsql;
  end if;
end;

 

4.通过job 每天凌晨12点重置序列

variable seq_job number;               
begin
  sys.dbms_job.submit(job => :seq_job,
                      what => ' begin reset_seq; end;',
                      next_date => sysdate,
                      interval => 'TRUNC(SYSDATE + 1)');
  commit;
end;
