Ref cursor in stored proc

   Hello

   If I call a function from a stored procedure and the function returns a ref cursor. The only info I have and want is that this ref cursor has a field, "NAME", but I know nothing of all other fields, how do I fetch this field name?

E.g. this does not work since the ref cursor has many values, not just NAME.

   FUNCTION TESTFUNCTION(input_var IN VARCHAR2) RETURN VARCHAR2 IS

   	TYPE RecType IS RECORD(nome IMPRESA_PARIX.NAME%TYPE);
     Cursore IMP_REFCUR;
	rec RecType;
   BEGIN
   	-- Call function that returns IMP_REFCUR (ref cursor)
     Cursore := SEARCH_PARAMETRICA('MKM S.R.L.');

     LOOP
         FETCH Cursore INTO rec;
         DBMS_OUTPUT.PUT_LINE(rec.NAME);
         EXIT WHEN Cursore%NOTFOUND;
     END LOOP;

     RETURN NULL;
