Prototype (C/C++)

HRESULT GetAltSnapshotFolder(SQLDMO_LPBSTR pRetVal);
HRESULT SetAltSnapshotFolder(SQLDMO_LPCSTR NewValue);

注释

If used with the MergePublication2 or TransPublication2 objects, the AltSnapshotFolder property specifies an alternate location to use for snapshot file creation when a snapshot must be transported to a Subscriber. If used with the MergePullSubscription2 or TransPullSubscription2 objects, AltSnapshotFolder specifies an alternate location to use for snapshot file application.

Transporting a snapshot file using portable media, such as a removable hard drive, can be useful in situations where a Subscriber is not continuously connected. Transporting a snapshot file may also be desirable in a situation where a large amount of data might otherwise need to be applied using an expensive connection.

AltSnapshotFolder is required if the publication attribute SQLDMOPubAttrib_InternetEnabled is set.

注意注意

If an application sets AltSnapshotFolder with the MergePublication2 or TransPublication2 object after the initial snapshot has been created, a new snapshot must be generated. Snapshots are applied when the next scheduled snapshot agent runs.
注意注意

If an application calls AltSnapshotFolder on an instance of Microsoft SQL Server version 7.0, the constant, SQLDMO_E_SQL80ONLY, and the message "This property or method requires Microsoft SQL Server 2000 or later" are returned.
