Going through rows and adding up numbers

noobTalendDev — Fri, 15 Nov 2024 23:36:22 GMT

Here is how the data is formatted from my tLogRow (i am reading an xlsx file).

Essentially I want to go through all of these rows and add up the numbers and assign them to the respective users. I am new to talend and couldn't really figure this part out if anyone can provide some guidance.

Input:

user1 | 5|

user2 | 2|

user3 | 1|

user4 | 3|

user1 | 2|

user2 | 6|

user3 | 8|

user10 | 4|

user11|30|

Output:

user1 | 7|

user2 |8|

user3 |9|

user4 |3|

user10|4|

user11|30|

I ended up using tSurviveFields to fix this issue, anyone else have any other methods of doing this?

Hi, you can use tAggregateRow component , you choose the first field as group by element and you select a sum for the second one in Operations.
