ReplicationDatabase.MergePublications Property

Returns the merge publications defined on the replication database.

Namespace:  Microsoft.SqlServer.Replication
Assembly:  Microsoft.SqlServer.Rmo (in Microsoft.SqlServer.Rmo.dll)

public MergePublicationCollection MergePublications { get; }

MergePublication objects in a MergePublicationCollection can be accessed using a string indexer (name) or a numeric indexer (ordinal).

The MergePublications property returns all merge publications for members of the db_owner and replmonitor fixed database roles. For all other users, the MergePublications property returns only publications for which the user is a member of the publication access list (PAL).
