如何从cx_Oracle中的callfunc获取自定义对象? [英] How to get custom object from callfunc in cx_Oracle?

问题描述

我有一个PL/SQL函数 my_function ，该函数返回自定义对象:

I have an PL/SQL function my_function that returns custom defined object:

CREATE OR REPLACE TYPE "TP_ACTION" AS OBJECT
   (
  stop_time timestamp,
  user_name varchar2(64),
  error_msg tp_message_l,

CONSTRUCTOR FUNCTION TP_ACTION(
   usrnm in varchar2 := null
) RETURN SELF AS RESULT,

  MEMBER PROCEDURE doClose(pi_session_MD5 IN  VARCHAR2),
  member procedure setRunStatus(status in varchar2),
)  

因此，在python中，我将该函数称为:

Therefore in python I call that function:

var_type = cursor.var(cx_Oracle.OBJECT, typename='TP_ACTION')
cursor.callfunc('my_function', var_type, params)

在那之后我得到了异常:

After that I get exception:

 cx_Oracle.NotSupportedError: Variable_TypeByPythonType(): unhandled data type.

是否有可能通过调用PL/SQL函数获得自定义对象?也许还有另一种方式来获得它?

Is it even possible to get custom definded object by calling PL/SQL function? Or maybe there is another way to get it?

推荐答案

绑定Oracle对象的功能仅在未发行(开发)的cx_Oracle版本中可用.这是调用返回对象的函数所必需的.如果您可以使用开发版本，则您的代码将起作用；否则，请等待正式发布.

The ability to bind Oracle objects is only available in the unreleased (development) version of cx_Oracle. This is needed for calling a function that returns an object. If you can make use of the development version your code will work; otherwise, please wait for the official release.
