oracle 创建job 定时调度存储过程

1、建表

create  table test_job(para_date date); 
commit; 

insert into test_job values(sysdate); 
commit; 

select  * from test_job;

2、建立存储过程

create  or replace  procedure test_jobproce as 
begin 
insert into test_job values(sysdate); 
end test_jobproce;

3、创建job，job创建之后是默认执行的

declare test_job_really  number; 
begin 
 dbms_job.submit(test_job_really,'test_jobproce;',sysdate,'sysdate+1/1440'); 
commit; 
end;

4、可手动执行和停止执行job

先获取到job的编号：

select  * from sys.user_jobs

启动job：

begin 
 dbms_job.run(25); 
commit; 
end;

停止job：

begin 
 dbms_job.broken(25,true);
 commit; 
end;

删除job：

begin 
 dbms_job.remove(25); 
commit; 
end;

定义job，设定每个月执行一次

---创建job 每个月定时执行一次
declare job_fixed_pay_into_listofcost  number; 
begin 
 dbms_job.submit(job_fixed_pay_into_listofcost,'proc_fixed_pay_into_listofcost;',sysdate, 'TRUNC(LAST_DAY(SYSDATE ) + 1)' ); 
commit; 
end; 

select * from dba_jobs;

关于设定定时任务的参数解析：

描述                    INTERVAL参数值
每天午夜12点            'TRUNC(SYSDATE + 1)'
每天早上8点30分         'TRUNC(SYSDATE + 1) + （8*60+30）/(24*60)'
每星期二中午12点         'NEXT_DAY(TRUNC(SYSDATE ), ''TUESDAY'' ) + 12/24'
每个月第一天的午夜12点    'TRUNC(LAST_DAY(SYSDATE ) + 1)'
每个季度最后一天的晚上11点 'TRUNC(ADD_MONTHS(SYSDATE + 2/24, 3 ), 'Q' ) -1/24'
每星期六和日早上6点10分    'TRUNC(LEAST(NEXT_DAY(SYSDATE, ''SATURDAY"), NEXT_DAY(SYSDATE, "SUNDAY"))) + （6×60+10）/（24×60）'
