Write a query to extract

Hello,

I want to write a query to extract the same informations than we can find in the "report" section. I choose the "Détail des charges par ressource - mensuel" section.

I succed to connect and write the query, but the order the activities are display is not the same than in the report.

A try with an order by clause "order by project.project_order, activity.id" but without success … can see a Screenshot in attachment

Thanks for any ideas, informations or help
