Комментарии

Метод Create может вызываться членами предопределенных sysadmin ролей сервера на издателе. Его также могут вызывать члены предопределенных db_owner ролей базы данных в базе данных публикации.

Вызов Create эквивалентен выполнению sp_addarticle (Transact-SQL) для репликации транзакций или моментальных снимков или выполнению sp_addmergearticle (Transact-SQL) для репликации слиянием.
