HasPrimaryKey Property
この機能は、将来のバージョンの Microsoft SQL Server では削除される予定です。 新しい開発作業では、この機能の使用を避け、現在この機能を使用しているアプリケーションは修正するようにしてください。

説明
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.
