Answer 1

I tried like this......
create table ex_abc
as SELECT   'Jim' Col1, 200 Col2 FROM DUAL
                 UNION ALL
                 SELECT   'Jack', 300 FROM DUAL
                 UNION ALL
                 SELECT   'Jon', 400 FROM DUAL;
select * from   ex_abc;     
Col1 Col2
Jim 200
Jack 300
Jon 400

/* Formatted on 06/07/2013 1:58:47 PM (QP5 v5.126.903.23003) */
DECLARE
   v_String    VARCHAR2 (4000);
   v_String1   VARCHAR2 (4000);
   v_a         VARCHAR2 (4000);-- := 'Jack 300 Jim 200 Jon 400';
   v_count     NUMBER;
BEGIN
   SELECT   listagg (col1 || ' ' || col2, ' ') WITHIN GROUP (ORDER BY col1)
     INTO   v_a
     FROM   ex_abc;
   SELECT   regexp_count (v_a, '[^ ]+') INTO v_count FROM DUAL;
   FOR i IN reverse 1 .. v_count
   LOOP
      v_String :=
            'SELECT regexp_substr('
         || ''''
         || v_a
         || ''''
         || ',''[^ ]+'',1,'
         || i
         || ')   FROM dual';
      v_String1 := '(' || v_String || ') col'||i||',' || v_String1;
   END LOOP;
   DBMS_OUTPUT.PUT_LINE(   'select '
                        || SUBSTR (v_String1, 1, LENGTH (v_String1) - 1)
                        || ' from dual');
END;
Output:
--A dynamic select query will be generated as below:
select (SELECT regexp_substr('Jack 300 Jim 200 Jon 400','[^ ]+',1,1)   FROM dual) col1,(SELECT regexp_substr('Jack 300 Jim 200 Jon 400','[^ ]+',1,2)   FROM dual) col2,(SELECT regexp_substr('Jack 300 Jim 200 Jon 400','[^ ]+',1,3)   FROM dual) col3,(SELECT regexp_substr('Jack 300 Jim 200 Jon 400','[^ ]+',1,4)   FROM dual) col4,(SELECT regexp_substr('Jack 300 Jim 200 Jon 400','[^ ]+',1,5)   FROM dual) col5,(SELECT regexp_substr('Jack 300 Jim 200 Jon 400','[^ ]+',1,6)   FROM dual) col6 from dual;
The output of above query is:
Col1          Col2             Col3         Col4         Col5          Col6
Jack     300     Jim     200     Jon     400Edited by: nkvkashyap on Jun 7, 2013 2:16 AM
