Comment déterminer la taille de ma base de données SQL Server?

De base: quelle est la taille sur le disque de ma base de données MS SQL Server?
Pour en savoir plus: puis-je voir rapidement où se trouvent les données? c'est-à-dire quels tableaux, journaux, etc.

Vous voudrez probablement commencer par la commande sp_spaceused.

Par exemple:

sp_spaceused Renvoie des informations sur la taille totale de la base de données

sp_spaceused 'MyTable' Renvoie des informations sur la taille de MyTable

Lisez les documents pour tout ce dont vous pouvez obtenir des informations. Vous pouvez également utiliser la commande sp_msforeachtable pour exécuter sp_spaceused sur toutes les tables à la fois.

Modifier: sachez que la commande renvoie parfois plusieurs ensembles de données, chaque ensemble contenant un bloc différent de statistiques.

La manière la plus simple (pas de saisie!): Dans SQL 2005/8 de Management Studio, cliquez avec le bouton droit sur la base de données, sélectionnez Rapports, Rapports standard, Utilisation du disque (également Par tables, table et partition).

Ce script parcourt toutes les tables de la base de données actuelle et montre combien d'espace chacune prend pour les données, les index et l'espace inutilisé:

Vous pouvez voir les fichiers physiques dans sys.database_files. Cela a le chemin d'accès au fichier et la taille (dans les blocs IIRC).

sp_spaceused vous montrera combien d'espace un objet individuel prend.

exécutez ceci pour obtenir la taille par table:

Il s'agit d'une requête/vue qui obtient toutes ces informations, et bien plus, sans curseurs ou boucles "maléfiques". ;-)
