Комментарии

Перечисление PublicationAttributes поддерживает FlagsAttribute параметр , который позволяет использовать побитовое сочетание значений перечисления. Сведения о значениях атрибутов по умолчанию для публикаций транзакций или моментальных снимков и публикаций слиянием см. в разделе sp_addpublication (Transact-SQL) и sp_addmergepublication (Transact-SQL).

Свойство Attributes может быть получено только членами sysadmin предопределенных ролей сервера на издателе, членами db_owner предопределенных ролей базы данных в базе данных публикации или пользователями в списке доступа к публикации (PAL).

Свойство Attributes может быть задано только членами sysadmin предопределенных ролей сервера на издателе или членами db_owner предопределенных ролей базы данных в базе данных публикации. Пользователи в pal могут задать Attributes свойство существующей публикации.

Attributes Получение свойства эквивалентно выполнению sp_helppublication или sp_helpmergepublication.

Attributes Задание свойства эквивалентно выполнению sp_addpublication и sp_changepublication или sp_addmergepublication и sp_changemergepublication.
