• oracle 里面定时执行任务,比如存储过程内容等


    DECLARE
       job_no_ NUMBER;  
    BEGIN  
       DBMS_JOB.SUBMIT(job_no_,
                       'proc_qszx_dw_sc(''040100'');',             -- 一般会将 insert into 语句写到一个存储过程insert_Prod中
               sysdate,
                       'TRUNC(sysdate)+1+2/24');     -- 2/24 每天凌晨2点
       COMMIT;
    END;


     select
    job,last_date,last_sec,next_sec,total_time,interval,what
    from user_jobs

    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; 

    亲身实践过的demo:

    begin
      dbms_job.what('405','day_dw_sc_for_gsdm(''040100'');');  
    --dbms_job.remove('404');  
      /* job_no_ NUMBER;  
    BEGIN  
       DBMS_JOB.SUBMIT(job_no_,
                       'proc_qszx_dw_sc(''040100'');',             -- 一般会将 insert into 语句写到一个存储过程insert_Prod中
               sysdate,
                       'TRUNC(sysdate)+1+6/24');     -- 2/24 每天凌晨2点
       COMMIT;*/
    END;
