sql - 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
-------------------------------------
1   2016-05-01  10       0      10
1   2016-05-02  2       -1      11
1   2016-05-03  0       -5      6
1   2016-05-04  0       -1      5 

assume I have a table "table_a" that has a column (ID, name, date, input, output). how to create query with results as above.

Answer 1

You can use SUM OVER function:

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