pdo 怎么调用oracle 返回游标的存储过程

Question

存储过程是这样的

1.

CREATE OR REPLACE PROCEDURE HR.get_job_info_sp (v_job_id OUT varchar2)
IS
BEGIN
   SELECT job_id
   INTO v_job_id
   FROM jobs
   WHERE job_id='oooo';
END;

2.

CREATE OR REPLACE PROCEDURE hr.get_job_sp_by_id (c_list OUT sys_refcursor)
IS
BEGIN
   OPEN c_list FOR
      SELECT job_id
      FROM jobs;
END;

现在只知道第一个获取单个out值的怎么写

$result = $conn->prepare("BEGIN get_job_info_sp(:v_job_id); end;");
            $result->bindParam(":v_job_id", $v_job_id, PDO::PARAM_STR, 300);
            $result->execute();

第二个返回游标的怎么获取？
