Apply Join operator on each Attribute
Hello everyone,
As usual, I'm sorry if the question has already been posted before - although I carefully checked...
Here is my issue. I have an Example Set_1 containing an attribute called Date, and a variable number n of attributes called People_1 to People_n. I also have another Example Set_2 containing a list of names and biographic datas.
In order to get for each date the biographic datas of each people involved that day, I would like to apply the Join Operator to each attribute People_i (i=1 to n) using their names as Key attributes.
For now, as n is still small (7), I can do it by hand, parametring 7 Join Operators for each People attribute, and joining my 7 resulting sets in the Append Operator. But, I would like to get the same result automatically, in case of n becomes too big (parametring 40 Join Operators and connecting all them to an Append seems quite heavy and inelegant to me).
I've tried during past week to find an elegant solution to that problem, and I haven't been able to figure it. I've tried Loops of all kind, Subprocesses, etc. It seems very simple though, but I've been unable to get my "hand" results automatically.
Here are some of my datas to help you.
Thanks a lot, as always :-)

I'm sure I'm missing something important, but have you tried the De-Pivot operator before the join?

Hi @SylvainM,
Based on the 2 examplesets of your post, could you post a resulting exampleset of what you want to obtain, to better understand.
Regards,
Lionel

Hello Lionel,
Thank you for your help :-)
This is what I get "by hand" (please, consider that my bio datas aren't complete yet, some names are missing, which explains why I don't have a row for each person indicated by my previous Example sets)

Hi Lionel,
So I don't know if I did it correctly (I'm very bad with computers), but this is the "joining" part of the process. It takes as inputs the intermediary results I gave in my previous post.
Thanks so much!
Sylvain
