Accessing another user's table within an Oracle Stored Procedure

I'm writing a stored procedure to copy data from one user's table to another schema. Basically, it is a series of INSERT .. SELECT statements such as this:

INSERT INTO GESCHAEFTE
  SELECT *
    FROM TURAT03.GESCHAEFTE
   WHERE kong_nr = 1234;

This works fine when issueing from sqlplus (or TOAD for me ;-)) so I know that I have sufficient privileges, but when this is part of stored procedure like this:

CREATE OR REPLACE FUNCTION COPY_KONG
    (pKongNr IN NUMBER)
    RETURN NUMBER
    AUTHID CURRENT_USER
IS
BEGIN
   INSERT INTO GESCHAEFTE
      SELECT *
       FROM TURAT03.GESCHAEFTE
       WHERE kong_nr = pKongNr;
END;

I get an Oracle error:

[Error] ORA-00942 (11: 22): PL/开发者_运维技巧SQL: ORA-00942: table or view does not exist

As you can see, I've already inserted an AUTHID, but to no avail.

What else can I do? I'm pretty much at the end of my ideas here.

The owner of a procedure must be granted privilege to access the underlying objects directly, not through a role. To have the same level of access as your procedures, use the following commands:

SET ROLE NONE;

To access another table from a procedure, you need to be granted SELECT directly, not through a role:

GRANT SELECT ON TURAT03.GESCHAEFTE TO <your_user>;
