Замечания

ThePublicationAttributes property is a bit-packed value that specifies one or more allowed functions. Combine values using the OR logical operator.

For a referenced, Subscriber-initiated subscription, PublicationAttributes is SQLDMOPubAttrib_Min until synchronization occurs and the Subscriber can determine the attributes.

To enable anonymous subscriptions, SQLDMOPubAttrib_AllowPull, SQLDMOPubAttrib_AllowAnonymous and SQLDMOPubAttrib_ImmediateSync must all be specified.

If the SQLDMOPubAttrib_InternetEnabled attribute is specified, the AltSnapshotFolder property must be specified. If the AltSnapshotFolder property is set to NULL or an empty string, SQLDMOPubAttrib_InternetEnabled is automatically turned off.

ПримечаниеПримечание

If an application sets PublicationAttributes with the MergePublicationor TransPublication object with a setting of SQLDMOPubAttrib_CompressSnapshot, SQLDMOPubAttrib_InternetEnabled, or SQLDMOPubAttrib_SnapshotInDefaultFolder after the initial snapshot has been created, a new snapshot must be generated and then reapplied to each subscription. Snapshots are applied when the next scheduled snapshot and distribution or merge agent run.
