Hello

I have this table:

i want to join this tables with 2 other tables: one will give me the country, the other will give me the city. They look like this

What I want:

I use tmap to make the joins

I want 2 outputs in tmap :

The first output is : as long as I have a country or a city, i want to have a table with the id, the country, the city

The 2nd output is : if I don't have the city and the country i want to have a table with the CODE and the CAP code

I'm stuck because I d'ont know know to configure the tmap, I tried with catch lookup inner join reject = true, but my first outpu will awalys catch rows where I have country and a city but I want country or a city

can you help me?

You can't implement it with only one tMap, because it uses the AND operation and cannot be set or operation if there are multiple conditions. I think you need to do the join two times, one for CODE code and another for CAP code, then, do an inner join between the two results based on ID column to merge the all columns (ID, country, city), filter the rows using tFilterRow with the condition the city or the country is not empty.
