如何从Codeigniter调用Oracle存储过程

Question

我的存储过程：

CREATE OR REPLACE procedure SELECT_ACC_CHART_OF_ACCOUNTS (ALLS out sys_refcursor)
   is
    begin
       open ALLS for select * from USERS;
    end;

Codeigniter代码：

$query = $this->db->query("CALL SELECT_ACC_CHART_OF_ACCOUNTS()");
echo "<pre>";print_r($query->result());die();

这正在显示以下错误：

A PHP Error was encountered
Severity: Warning

Filename: oci8/oci8_driver.php
