Problem Merge 2 tables

hello everybody,

I’m trying to solve a problem but I haven’t found anything on the forum.

I would like to merge two tables containing in the first one numbered addresses and in the second one the names of the authors and the number of their affiliation.

I want to match the affiliation number in table 2 with that in table 1 to assign the address to the right author to obtain the final table.

Does anyone have an idea?

Thank you for your help,

Best regards,

Right outer join on the affiliation columns:

Keep only Addresses from Table 1:

Result of the joiner node:

Compare to your final table:
