Générer un script de création pour tous les index
Je travaille sur la documentation de mes bases de données et je voudrais créer une liste de tous les index de ma base de données. La raison pour laquelle je veux le faire est que je puisse suivre les modifications de mes index au fil du temps. J'ai actuellement une feuille de calcul avec tous les index qui ont changé depuis que j'ai créé cette feuille de calcul, mais elle n'a pas tous les index. Au lieu d'avoir à scénariser chaque index, j'aimerais pouvoir simplement générer la liste. J'ai joué avec les vues du système mais je n'ai pas pu le comprendre.
Comment puis-je générer une liste d'index et l'instruction create pour chaque index?
Je ne semble pas avoir un script comme celui-ci dans ma boîte à outils, mais j'en ai trouvé d'autres dans ma recherche.
Avez-vous déjà vu ce script?

Il utilise un curseur, ce qui n'est probablement pas strictement nécessaire. Mais je peux généralement les nettoyer pour éviter un curseur en utilisant le FOR XML et potentiellement une mise à jour excentrique pour concaténer les chaînes.

J'ai trouvé cette réponse sur mssqltips et voici le lien vers l'article que j'ai trouvé là-bas.
Je poste également le TSQL pour possible link-rot à l'avenir.

J'espère que cela aide quelqu'un.

J'utilise SQL 2014 et réponse de Devraj Gadhavi avait besoin de quelques corrections. Le facteur de remplissage de 0 doit être de 100 et j'avais besoin de GO instructions pour le faire fonctionner.
