Recherche d'un moyen de créer plusieurs colonnes qui effectuent la moyenne des données par différents regroupements dans la même requête SQL

Question

Cette requête nous fournit l'heure de diverses opérations. À l'heure actuelle, il divise le temps de chaque événement par nom, date et modèle de pelle. Cependant, je cherche à joindre d'une façon ou d'une autre la moyenne de tous les noms d'une équipe dans une nouvelle colonne. Étant nouveau dans le jeu SQL, il serait bien d'avoir une stratégie qui pourrait fournir diverses définitions de moyenne et les retourner à la même table. Une image de la sortie suit ce lien.

Vous pouvez utiliser la fonction OVER (PARTITION BY). De cette façon, vous pouvez utiliser la répartition que vous souhaitez obtenir pour votre moyenne, en partitionnant l'ensemble de données de différentes manières. Vous pouvez en savoir plus sur OVER Clause here.

Exemple:

SELECT 
    DateField 
    ,YourName1 
    ,YourId 
    ,SUM(Value1) 
    ,AVG(Value1) OVER (PARTITION BY DateField) AS DateFieldAverage 
FROM 
    YourTable 
GROUP BY 
    DateField 
    ,YourName1 
    ,YourId 

En supposant que vous utilisez SQL Server (basé sur la syntaxe au-dessus de votre question).
