Bonjour,

Je suis chargé d'extraire certaines données, par mois, d'une table contenant des données de ventes.

J'ai fait une procédure stockée et la résultat obtenu est ok. Par contre, j'aimerais accélérer le temps d'exécution est, pour le mois où il y a le plus de ventes, de 33 secondes.

Il s'agit d'une vieille table (probablement transposée en sql serveur depuis un ancien système de stockage sans repenser la structure) avec plein de colonnes (une table obèse je crois que ça s'appelle). Bref, j'ai déjà fait quelques aménagements (ajout d'un id et quelques index) qui rendent les recherches courantes suffisamment performante.

Par contre ici, je sèche un peu... J'ai toujours du mal à savoir quelles colonnes mettre dans l'index et quelles colonnes mettre dans la clause include.

Voici la table en question :
