MODIFIER
Ok, j'ai votre problème dans vos requêtes mises à jour. Les deux cas de l'instruction If doivent renvoyer le même type de données de résultat, donc lorsque vous essayez de convertir les valeurs de date en numérique, votre vrai cas renvoie varchar champ de type de données qui est TOTAL et le champ else renvoie un numeric champ de type, ce qui provoque l'erreur.
Pour le résoudre, vous devez supprimer l'instruction case, cela fonctionnera correctement selon vos besoins.
select
CASE WHEN (GROUPING(shipping_company) = 1) THEN 'TOTAL'

CONVERT(numeric, (SUBSTRING(ship_date, 1, 6))) AS Date,

ELSE shipping_category END AS shipping_category,
sum(convert(decimal(10,2),shipping_cost))

group by shipping_company, (CONVERT(numeric, SUBSTRING(ship_date, 1, 6))),
