Oracle Scheduler Job and Argument

drop table scheduler_test;
create table scheduler_test(x varchar2(200), y int);
truncate table scheduler_test;
select * from scheduler_test order by 1;

begin
  dbms_scheduler.drop_job('ttt');
  dbms_scheduler.purge_log(job_name => 'ttt');
end;
/

create or replace procedure p_1(p_x varchar2)is
begin
  insert into scheduler_test(x) values(p_x);
  commit;
end;
/

当 使用job_type=sp调用一个sp的时候，必须指定所有参数
因为没有定义program，所以只能用 argument_position指定
-- use stored_procedure as job_type and set arguments
declare
  l_x integer := 0;
begin
  dbms_scheduler.create_job(job_name        => 'ttt',
                            job_type    => 'stored_procedure',
                            job_action => 'p_1',
                            number_of_arguments => 1,
                            start_date      => systimestamp,
                            repeat_interval => 'freq=minutely;interval=1;bysecond=0,20,40');

  dbms_scheduler.set_job_argument_value('ttt',argument_position => 1,argument_value => to_char(systimestamp));  
  dbms_scheduler.enable('ttt');
end;
/

如 果job_type=plsql_block调用sp，不能通过set_job_argument_value指定参数
但是可以构造 字符串。并且可以使用Metadata Attributes来作为参数（如下的job_start）
-- use plsql_block as job_type and use scheduler metadata as arguments
declare
  l_x integer := 0;
begin
  dbms_scheduler.create_job(job_name        => 'ttt',
                            job_type    => 'plsql_block',
                            job_action => 'p_1(job_start);',
                            start_date      => systimestamp,
                            repeat_interval => 'freq=minutely;interval=1;bysecond=10');

  dbms_scheduler.enable('ttt');
end;
