Exemple de script OLE Automation
Cette rubrique contient un exemple de lot d'instructions Transact-SQL qui utilise les procédures stockées OLE Automation pour créer et utiliser un objet SQL-DMO SQLServer dans l'instance locale du Moteur de base de données SQL Server 2005. Certains extraits du code sont utilisés comme exemples dans les rubriques de référence des procédures stockées système OLE Automation.
