Answer 1

Hi,
There's one thing in your example, regarding the last line:
def 04/01/2009 10 180 30 30I assumed you meant:
def 04/01/2009 10 180 30 100 <<== running total should be 100Am I correct?
Then try:
SQL> with t as (
  2  select  'Abc' col1, to_date('04/01/2009', 'dd/mm/yyyy') col2, 100 col3, 50 col4 from dual union all
  3  select'abc', to_date('04/01/2009', 'dd/mm/yyyy'), 70, 20 from dual union all
  4  select 'def', to_date('04/01/2009', 'dd/mm/yyyy'), 10, 30 from dual
  5  ) --Actual query starts here:
  6  select col1
  7  ,      col2
  8  ,      col3
  9  ,      sum(col3) over (order by rownum) rt_col3
10  ,      col4
11  ,      sum(col4) over (order by rownum) rt_col4
12  from t;
COL COL2             COL3    RT_COL3       COL4    RT_COL4
Abc 04-01-2009        100        100         50         50
abc 04-01-2009         70        170         20         70
def 04-01-2009         10        180         30        100Edited by: hoek on Jun 24, 2009 5:19 PM added question
