[QSqlQuery] Requête non active

Bonjour,

Je vous sollicite aujourd'hui car j'ai un problème dans une de mes classe, j'essaye de faire des requêtes préparées grâce au module QtSql.
Seulement voila, mes requêtes sont tout inactive quand je les testes du coup impossible de récupérer les données de retour.

Voici ma classe:
