SQL> desc dbms_job;

IS_JOBQ??????????? FUNCTION?

2.用戶下的job信息
select * from user_jobs;
正在運行的job
select * from dba_jobs_running;

3.創建job
variable jobid number;
begin
? dbms_job.submit(:jobid,'proc_CreateAllStreportData(1);',trunc(sysdate)+18/24,'trunc(sysdate)+1+18/24');
end;
/
show err;

begin
sys.dbms_job.submit(job => :job,
????????????????????? what => 'P_CLEAR_PACKBAL;',
????????????????????? next_date => to_date('04-08-2008 05:44:09', 'dd-mm-yyyy hh24:mi:ss'),
????????????????????? interval => 'sysdate+ 1/360');
commit;
end;
/

4.刪除job
exec dbms_job.remove(job_id);
exp:
exec dbms_job.remove(41);
commit;--不加commit是刪不掉的

5.運行JOB
?begin
??dbms_job.run(:job1);
?end;
?/

6.中止job
?dbms_job.broken(:job1);
7.修改job
?dbms_job.change(:job,:what,:next_date,:interval);
?dbms_job.what(:job,:what);
?dbms_job.next_date(:job,:next_date);
?dbms_job.instance(:job,:instance);?
?dbms_job.interval(:job,:interval);?
?dbms_job.broken(:job,:broken,:next_date);??
