Remarques
DatabaseName est une propriété obligatoire et doit être définie avant la création de l’abonnement sur le serveur. Une fois que l’abonnement existe sur le serveur, la DatabaseName propriété ne peut pas être modifiée.
La DatabaseName propriété ne peut être récupérée que par les membres du sysadmin rôle serveur fixe sur l’Abonné ou par les membres du db_owner rôle de base de données fixe sur la base de données d’abonnement.
La DatabaseName propriété ne peut être définie que par les membres du sysadmin rôle serveur fixe sur l’Abonné ou par les membres du rôle de base de db_owner données fixe sur la base de données d’abonnement.
La récupération de la DatabaseName propriété équivaut à exécuter sp_helppullsubscription (Transact-SQL) ou sp_helpmergepullsubscription (Transact-SQL).
La définition de la DatabaseName propriété équivaut à exécuter sp_addpullsubscription (Transact-SQL) ou sp_addmergepullsubscription (Transact-SQL).
