Quelle est la meilleure façon de copier une base de données?

Il est possible de sauter l'étape de la création de la base de données vide. Vous pouvez créer la nouvelle base de données dans le cadre du processus de restauration.

Ceci est en fait le plus facile et la meilleure façon que je connaisse pour cloner une base de données. Vous pouvez éliminer les erreurs de script par la sauvegarde et de restauration processus plutôt que de l'exécuter à travers le SQL Server Management Studio

Il y a deux autres options que vous pouvez explorer:

1. Détachez la base de données, copiez le fichier .mdf et refixer.
2. Utiliser SQL Server Integration Services (SSIS) pour copier tous les objets sur

Je suggère coller avec la sauvegarde et la restauration et l'automatisation si nécessaire.

Voici un script SQL dynamique que je l'ai utilisé dans le passé. Il peut encore être modifié, mais il vous donnera les bases. Je préfère élaborer le script pour éviter les erreurs que vous pouvez faire en utilisant le Management Studio:

Declare @NewDB varchar(100)
Declare @vchBackupPath varchar(255)
