FIX: Replication Queued Updating Supports Unique Constraints (322384)

SYMPTOMS

The Distribution Agent may fail and go offline with the following error message:

Violation of UNIQUE KEY constraint 'xyz'. Cannot insert duplicate key in object 'looptest'. 2627

CAUSE

This occurs when a unique constraint is defined on a published article on the publisher and the subscriber when implementing replication's queued updating feature.

NOTE: SQL Server 2000 Service Pack 2, and earlier, does not provide support for unique constraints defined on the published table at the publisher and subscriber in a queued updating environment. This support is now offered in SQL Server 2000 post-service pack 2 version 8.00.0621.
