You want to load additional datas to your excel file.

Therefor you have to define where the datas are from.

on the right site there are your data connections. I only can see the connection to your data folder.

Maybe some rights are missing for you to use ODBC-data connections?

i think probably the probably is in how Qliksense read sql query 

because i have done another simple query and it works

But this one doesn't work :

Data are loaded from an excel file for Power_Consumption_Raw table

in the script editor, on the right side, there are your connections.

connections to folders or to ODBC or REST or something else.

There are no database connection I can see in your screenshot.

The example that works use resident. resident is a command to load data inside the script, not from a file or a database.
