Sql greater than 32k in sys_refcursor

Question

hi
We have to write function/procedure to form reports in java there we just bind the record sets into grid. We have to return the record set as SYS_REFCURSOR.
Most of the sqls are involved in pivoting and so query length is beat 32k.
Is there any way to pass the large sql to ref cursor?
    CREATE OR REPLACE FUNCTION TESTFUN (pREFCUR OUT SYS_REFCURSOR) RETURN NUMBER
    IS
        vSQLSTR VARCHAR2(32000);
        nRETURN NUMBER;
    BEGIN
        vSQLSTR := ' SQL > 32K ';
        OPEN pREFCUR FOR vSQLSTR;
            RETURN 1;
        EXCEPTION
            WHEN OTHERS THEN
                COMMONEXCEPTIONHANDLER(SQLCODE, SQLERRM); -- log errors which is having RAISE_APPLICATION_ERROR
                RETURN -1;
    END;version
SQL> select * from v$version;

using DBMS_SQL i can parse and execute sqls. But i have to return my output by refcursor. If it is PLSql limit, is there any work around available?

The only option I can think of for your Oracle version is:
1. create a pipelined function that uses DBMS_SQL to create rows for the result set. Here is a sample PIPELINED function; yours would gather the rows using DBMS_SQL.
CREATE OR REPLACE function get_emp_data
  return emp_table_type
  PIPELINED
  as
   TYPE EmpCurTyp IS REF CURSOR RETURN emp%ROWTYPE;
    emp_cv EmpCurTyp;
    l_rec  emp%rowtype;
  begin
    open emp_cv for select * from emp;
    loop
      fetch emp_cv into l_rec;
      exit when (emp_cv%notfound);
      pipe row( emp_scalar_type( l_rec.empno, LOWER(l_rec.ename),
          l_rec.job, l_rec.mgr, l_rec.hiredate, l_rec.sal, l_rec.comm, l_rec.deptno ) );
    end loop;
    return;
  end;
/ 2. create a simple procedure that opens and returns a REF CURSOR on a call to that pipelined procedure
OPEN myCursor FOR SELECT * FROM TABLE(get_emp_data);That 'myCursor' would be the REF CURSOR that gets returned to the client.
