oracle 数据库 包文件这样创建的

function pf_get_info(id in varchar2,

name out varchar2,

sex out varchar2,

birthdate out date,

cd_no out varchar2) return integer is

e_info_no_found exception;

begin

begin

select name,

decode(sex, '0', '男', '1', '女', '未知'),

birthdate,

nvl(cpr_no, '')

into rs_name, rs_sex, rdt_birthdate, rs_cd_no

from basic_info

where id = id;

exception

when NO_DATA_FOUND then

raise e_info_no_found;

end;

return 0;

--异常处理

exception

when e_info_no_found then

return - 1;

end pf_get_info;

python 使用 cx_Oracle.Cursor.callfunc(proc, returnType, [params]) 调用函数 ，out 为多种类型的多个参数该如何获取呢？我看网上都是返回一个值的函数调用，我的样例代码如下

import cx_Oracle

class HR:

def __enter__(self):

self.__db = cx_Oracle.Connection("user/[email protected]//127.0.0.1:1521/ydyf")

self.__cursor = self.__db.cursor()

return self

def __exit__(self, type, value, traceback):

self.__cursor.close()

self.__db.close()

def pf_get_info(self,id):

l_rs_name = self.__cursor.var(cx_Oracle.STRING)

l_rs_sex = self.__cursor.var(cx_Oracle.STRING)

l_rdt_birthdate = self.__cursor.var(cx_Oracle.DATETIME)

l_rs_cd_no = self.__cursor.var(cx_Oracle.STRING)

# as_sick_id = self.__cursor.var(cx_Oracle.STRING)

self.__cursor.callfunc("PKG_HR.pf_get_info",cx_Oracle.NUMBER,[id])

return l_rs_name,l_rs_sex,l_rdt_birthdate,l_rs_cd_no

ggg=HR

id="2094"

l_rs_name,l_rs_sex,l_rdt_birthdate,l_rs_cd_no=ggg.pf_get_info(id)
