Комментарии

Synchronize Вызовите метод для возвращенного TransSynchronizationAgent объекта, чтобы синхронизировать подписку.

Перед получением синхронизации SynchronizationAgent подписки необходимо вызвать CommitPropertyChanges сохранение изменений свойств на сервере.

Если подписка создана со значением false forCreateSyncAgentByDefault, задание агент распространения для подписки не создается. Возможно, потребуется указать дополнительные свойства возвращаемого TransSynchronizationAgent объекта, прежде чем его можно будет использовать для синхронизации подписки.

Свойство SynchronizationAgent может быть получено только членами предопределенной sysadmin роли сервера на издателе, членами db_owner предопределенной роли базы данных в базе данных публикации или членами списка доступа к публикации (PAL) для публикации, к которой принадлежит подписка.

SynchronizationAgent Получение эквивалентно выполнению sp_helpsubscription (Transact-SQL).
