Oracle中DBMS_JOB.SUBMIT的用法说明

用法DEMO:  
     DBMS_JOB.SUBMIT(:jobno,//job号   
                                     'your_procedure;',//要执行的过程   
                                     trunc(sysdate)+1/24,//下次执行时间   
                                     'trunc(sysdate)+1/24+1'//每次间隔时间   
                                   );   
     删除job:dbms_job.remove(jobno);   
     修改要执行的操作:job:dbms_job.what(jobno,what);   
     修改下次执行时间:dbms_job.next_date(job,next_date);   
     修改间隔时间:dbms_job.interval(job,interval);   
     停止job:dbms.broken(job,broken,nextdate);   
     启动job:dbms_job.run(jobno);   

附:调用语句和参数说明:   

dbms_job.submit( job out binary_integer,

what       in   archar2,
next_date     in   date,
interval     in   varchar2,
no_parse     in   boolean)
其中:
●    job:输出变量,是此任务在任务队列中的编号;
●    what:执行的任务的名称及其输入参数;
●    next_date:任务执行的时间;
●    interval:任务执行的时间间隔。

 DEMO示例:

declare   
                jobid     number;   
                v_sql     varchar2(2000);   
    begin   
                v_sql:='begin   
                                      if     to_char(sysdate,''HH24:MI'')=''15:30''     then   -- 15:30执行
                                            insert     into     rjck.rkjl(cksj)     select     cksj     from     wzcs.ckjl;   
                                            dbms_output.put_line(''inserted     success'');   
                                      end     if;   
                                      commit;   
                                exception   
                                      when     others     then   
                                      rollback;   
                                      dbms_output.put_line(SQLERRM);   
                                end;   
                              ';   

                dbms_job.submit(jobid,v_sql,sysdate,'sysdate+1/1440');                   

                dbms_job.run(jobid);                   

                dbms_output.put_line('job     '||to_char(jobid)||'     is     running');    

end;
