Postgresql Execute doesn't show the result (SELECT query)

Hello, 

I'm trying to do a complexe PostgreSQL SELECT so i'm trying to use the Execute snap. (here is the snap settings : 

)

We can see in the pipeline execution statistics that he found the result i need (when i do this query in pgadmin i have the same amount of row (990)).

But i can't gather the data, neither in the pre-view, or in a mapper.
What can i do to get the data i need ? 

Thanks in advance,
