Je recherche une requête qui me fournirait des statistiques d’utilisation/de participation pour tous les utilisateurs d’un groupe spécifique. Nous avons des bénévoles qui aident la communauté et nous les avons tous regroupés dans le groupe principal « ninjas ». Je souhaite obtenir un tableau contenant des données incluant des éléments tels que : visites, sujets lus, messages lus, sujets créés, sujets auxquels répondu, nombre de messages privés, likes donnés, likes reçus, etc. J’aimerais pouvoir saisir la période et le nom du groupe en tant que paramètres. J’ai commencé avec cette requête que j’ai trouvée dans ce sujet, mais je ne suis pas sûr de savoir comment la limiter à un groupe spécifique.

Cette requête contient pratiquement tout ce qu’il faut. J’aimerais voir si time_read pourrait être ajouté en tant que colonne.
