Answer 1

So you still don't bother to write in proper understandable English or probably your keyboard is broken.
Any way you can do this
SQL> WITH t AS (
  2  SELECT 1 col_uid, 101 billno, 100 amount FROM DUAL UNION ALL
  3  SELECT 2, 102, 200 FROM DUAL UNION ALL
  4  SELECT 3, 103, 300 FROM DUAL)
  5  -- end test data
  6  select col_uid, billno, amount, decode(amount, amount_cum, null, amount_cum) amount_cum
  7    from (
  8  select t.*, (select sum(amount) from t t1 where t1.col_uid <= t.col_uid) amount_cum
  9    from t)
10  /
   COL_UID     BILLNO     AMOUNT AMOUNT_CUM
         1        101        100
         2        102        200 300
         3        103        300 600
