Membres

	Nom de membre	Description
	None	Identity columns are replicated to the Subscriber as the base data type.
	Automatic	Identity columns are marked as NOT FOR REPLICATION, and replication automatically assigns identity ranges.
	Manual	Identity columns are marked as NOT FOR REPLICATION, but replication does not assign identity ranges.

Notes

Identity range management is supported for both merge and transactional replication with updating Subscribers.

You should use Automatic whenever possible.

Automatic identity range management behavior is set by specifying PublisherIdentityRangeSize, SubscriberIdentityRangeSize, and IdentityRangeThreshold.

Manual is only used for snapshot and transactional replication without updates at the Subscriber, peer-to-peer transactional replication, or if your application must control identity ranges programmatically. With this option, you must ensure that ranges are assigned to the Publisher and each Subscriber, and that new ranges are assigned if the initial ranges are used.

None is only recommended for indexed views and for backwards compatibility with earlier versions of Microsoft SQL Server.

This namespace, class, or member is supported only in version 2.0 of the Microsoft .NET Framework.
