Oracle APEX cumulative sum / running total over month and year

hiddenonearth

Hello,

I am trying to implement an interactive report based on refreshing dynamics actions where a user can check the current visits per month and year for different accounts. He can select the data via a popup lov for the months and the year.

I'd like to implement a column where the running total is displayed by months for every account

For instance the number of visits for account01:

January: 150

February: 200

March: 50

...

___________________________________________________________________________

What I want to achieve is a running total by month and year filtered

January: 150

February: 350 (Jan + Feb)

March: 400 (Jan + Feb + Mar)

...

I tried this with the following SQL Query where I managed to get the total for every month and for every individual account but the cumulative sum for the next months is not working.

The data gets refreshed after another month is selected via the Popup LoV

    sum(count(*)) OVER (PARTITION BY user_account, to_char(year, 'YYYY'), to_char(month, 'MM') ORDER BY to_char(year, 'YYYY'), to_char(month, 'MM'),user_account)
     as sum_total
GROUP BY
    user_account,
    to_char(ord.year, 'YYYY'),
    to_char(ord.month, 'MM')

Any idea on how I can display the cumulative sum by the months.

Appreciate your help.

Thank you.

can you give some " sample data " like this:

with t as (Select 'account01' as account_name, '1990' as year, 'Jan' as month from dual
           Select 'account02' as account_name, '2000' as year, 'Feb' as month from dual
)
select ( your query here ) from t;

the seniors can help after checking the actual results of your query will return.
