Oracle Package Function

Question

hello,
I have written a package function but I cannot call it from .net environment correctly.
I want to ask you that is there anything wrong in the package:
Specification Part:
CREATE OR REPLACE PACKAGE SAGECM AS
TYPE T_CURSOR IS REF CURSOR;
FUNCTION COUNTREQ
p_ID IN VARCHAR2,
p_version IN VARCHAR2,
num_of_req OUT NUMBER
RETURN NUMBER;
END SAGECM;
Body Part:
CREATE OR REPLACE PACKAGE BODY SAGECM AS
FUNCTION COUNTREQ
p_ID IN VARCHAR2,
p_version IN VARCHAR2,
num_of_req OUT NUMBER
RETURN NUMBER
IS
BEGIN
SELECT count(*) INTO num_of_req FROM SAGECM_REQ WHERE ID=p_ID AND Version=p_version;
return num_of_req;
END COUNTREQ;
END SAGECM;

Answer 1

is there anything wrong in the packageYes. You are attempting to RETURN an OUT parameter. This is bad. I suspect you don't understand the difference between a procedure and a function....
CREATE OR REPLACE PACKAGE SAGECM AS
TYPE T_CURSOR IS REF CURSOR;
FUNCTION COUNTREQ
p_ID IN VARCHAR2,
p_version IN VARCHAR2
RETURN NUMBER;
PROCEDURE COUNTREQ
p_ID IN VARCHAR2,
p_version IN VARCHAR2,
num_of_req OUT NUMBER
END SAGECM;
CREATE OR REPLACE PACKAGE BODY SAGECM AS
  FUNCTION COUNTREQ
      p_ID IN VARCHAR2,
      p_version IN VARCHAR2
    RETURN NUMBER
  IS
    return_value NUMBER;
  BEGIN
    SELECT count(*) INTO return_value
    FROM SAGECM_REQ
    WHERE ID=p_ID AND Version=p_version;
    RETURN return_value;
  END COUNTREQ;
  PROCEDURE COUNTREQ
      p_ID IN VARCHAR2,
      p_version IN VARCHAR2,
      num_of_req OUT NUMBER
    ) IS
  BEGIN
    num_of_req := COUNTREQ(p_ID,p_version);
  END COUNTREQ;
END SAGECM;
