How to get total in data loader

[Anonymous]

Hello!

I have

year	month	value
2015	1	100
2015	2	600
2015	3	50
2016	2	300
2016	4	500
2016	8	800
2017	5	20
2017	7	40
2017	10	170
2017	12	600

And I want to calculate the share of each month in relation to the year.

In chart I can do it like this:

sum(total<month> value)/sum(total<year> value)

How can I do it in data loader?

Thanks.

Try this

Table:

LOAD * INLINE [

    year, month, value

    2015, 1, 100

    2015, 2, 600

    2015, 3, 50

    2016, 2, 300

    2016, 4, 500

    2016, 8, 800

    2017, 5, 20

    2017, 7, 40

    2017, 10, 170

    2017, 12, 600

];

Left Join (Table)

LOAD year,

Sum(value) as YearlySum

Resident Table

Group By year;

Left Join (Table)

LOAD month,

Sum(value) as MonthlySum

Resident Table

Group By month;

Thank you very much!

It works with small amounts of data. But the script is not executed if there are many entries in the tables.
