très lent import xml dans SQL Server 2016

Question

Je ne parviens pas à optimiser la requête de mise à jour suivante

requête SQL

Je suis en train d'importer ce fichier XML (https://ufile.io/8d9of), mais il faut compter entre 2-3 minutes pour terminer l'importation. Comment puis-je l'accélérer puisque le serveur n'est pas le problème (SQL Server 2016, ssd d'entreprise, Dual Xeon cpu et 256Go ddr4 ram)

Answer 1

Le chargement et l'analyse du XML est plutôt performant ... 585 enregistrements dans 0.108 secondes. Je soupçonne que la mise à jour provoque la dégradation. Peut-être en plaçant l'analyse XML dans un CTE, puis effectuer la mise à jour via un JOIN.

Avis I a ajouté deux champs et KID kFromDateLocal
