Osservazioni
Transactional replication requires a primary key to identify rows. If there is a primary key constraint on one of the columns, the table can be published as an article in a transactional publication as well as in a snapshot and merge publication. If there is no primary key constraint on the table, then it is not possible to publish this table in a transactional publication.
The HasPrimaryKey property can be retrieved by members of the sysadmin fixed server role at the Publisher or by members of the db_owner fixed database role on the publication database.
