Use CLOB & Ref Cursor

Question

Hi,
Can some one help.
I am getting string more than 32767 char so I want to use CLOB but I am unable to use in ref Cursor.
CREATE OR REPLACE PROCEDURE PM.PROC_CURSOR_BTDCS (P_QUERY IN varchar2, P_batchid out Number) AS
P VARCHAR2(32767);
P_CURSOR_QUERY SYS_REFCURSOR;
X_JOBID varchar2(30);
X_BATCHID VARCHAR2(1000);
X_CREF VARCHAR2(10000);
X_CLIENTREF VARCHAR2(10000);
X_CLIENTID NUMBER;
X_USERID NUMBER;
X_RDATE varchar2(40);
X_DDATE varchar2(40);
X_STAGE NUMBER;
X_DIFF NUMBER;
X_CLIENTDUEDATE varchar2(40);
X_ASSETID NUMBER;
X_MODEID NUMBER;
p_o_error VARCHAR2(100);
p_o_status NUMBER;
BEGIN
P := 'SELECT DISTINCT JOBID,CLID,USERID,STAGE,
GET_CSV_DATA(CURSOR (SELECT CREF FROM ('|| P_QUERY ||') WHERE jobid =A.JOBID AND CLID=A.CLID AND USERID=A.USERID AND RDATE=A.RDATE AND DDATE=A.DDATE AND STAGE=A.STAGE AND ASSETID=A.ASSETID AND CLDATE=A.CLDATE AND DIFF=A.DIFF)) C_CREF,

GET_CSV_DATA(CURSOR (SELECT Crefname FROM ('|| P_QUERY ||') WHERE jobid =A.JOBID AND CLID=A.CLID AND USERID=A.USERID AND RDATE=A.RDATE AND DDATE=A.DDATE AND STAGE=A.STAGE AND ASSETID=A.ASSETID AND CLDATE=A.CLDATE AND DIFF=A.DIFF)) C_CLIENTREF
,DIFF,cldate,ASSETID
,RDATE,DDATE,MODEID
FROM('||P_QUERY||') A';
--INSERT INTO FROG VALUES(P,sysdate);
OPEN P_CURSOR_QUERY FOR P;
LOOP
FETCH P_CURSOR_QUERY INTO X_JOBID
,X_CLIENTID,X_USERID,X_STAGE,
X_CREF,X_BATCHID,X_CLIENTREF,X_DIFF,

END LOOP;
CLOSE P_CURSOR_QUERY;
COMMIT;
END;

It would be helpful to indicate the error you're getting and the line where you're getting the error.
I will assume that your goal is to construct a SQL query > 32k, store that query in p, and open a cursor using p. In order to do that, you'd have to use the DBMS_SQL package, which is going to complicate your life rather significantly.
That said, it's far from obvious to my why the SQL statement needs to exceed 32k. At a minimum, concatentaing P_QUERY three times would seem unnecessary. If the text of P_QUERY exceeds 10,000 characters, I would really tend to suspect that you've done something wrong there and would benefit from simplifying the query or at least using a couple views.
