Remarques

ReplicationDatabase peut être utilisé pour représenter une publication ou une base de données par abonnement. ReplicationDatabase ne peuvent pas être utilisés pour représenter des bases de données système, telles que master, tempdb, msdb et modèle. Une base de données de distribution est représentée par DistributionDatabase.
