Notas

Transactional replication requires a primary key to identify rows. For an instance of Microsoft SQL Server, primary keys are implemented in PRIMARY KEY and UNIQUE key constraints.

If TRUE, the table contains a PRIMARY KEY constraint and can be published as an article in a transactional publication.

If FALSE, the table does not contain support for transactional replication and cannot be published as a transactional article.
