使用DBMS_SCHEDULER定時執行任務

create job

BEGIN
  DBMS_SCHEDULER.CREATE_JOB(job_name      => 'delete_goods_job',
                            job_type      => 'STORED_PROCEDURE',
                            job_action    => 'delete_goods',
                            repeat_interval => 'FREQ=SECONDLY; INTERVAL=6',
                            enabled       => true,
                            comments      => 'delete goods data'                  
                            );
END;
/

drop job

BEGIN
    DBMS_SCHEDULER.DROP_JOB(job_name => 'delete_goods_job'); 
END;
/

disable job

BEGIN
    DBMS_SCHEDULER.DISABLE(name => 'delete_goods_job'); 
END;
/

enable job

BEGIN
    DBMS_SCHEDULER.ENABLE(name => 'delete_goods_job'); 
END;
/

select jobs

select * from USER_SCHEDULER_JOBS;

query logs(感謝itpub的teddyboy)

select * from ALL_SCHEDULER_JOB_RUN_DETAILS
where owner = 'SCOTT'
order by log_date desc

delete logs

delete from ALL_SCHEDULER_JOB_RUN_DETAILS
where owner = 'SCOTT'
