oracle query sequential summation per rows

Question

I would like to ask to make a query like the following table?

-------------------------------------
ID   Date        Input  Output  Total
-------------------         


        

Answer 1

You can use SUM OVER function:

SELECT *,
    SUM(Input + Output) OVER(PARTITION BY ID ORDER BY Date) AS Total
FROM table_a

Answer 2

Use SUM() OVER(..) window function which produce cumulative sum :

SELECT t.id,t.date,t.input,t.output,
       SUM(t.output+t.input) OVER(PARTITION BY t.ID ORDER BY t.date) as Total
FROM YourTable t
