Remarks

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).
