Первое обновление BOL после выхода финальной версии SQL Server 2005 исправляет некоторые ошибки, замеченные пользователями.  

Дополнительно я бы рекомендовал загрузить обновление примеров баз данных для SQL Server 2005:

The samples download provides over 100 samples for SQL Server 2005, demonstrating the following components:

• Database Engine, including administration, data access, Full-Text Search, Common Language Runtime (CLR) integration, Server Management Objects (SMO), Service Broker, and XML
• Analysis Services
• Integration Services
• Notification Services
• Reporting Services
• Replication

The samples databases downloads include the AdventureWorks sample online transaction processing (OLTP) database, the AdventureWorksDW sample data warehouse, and the AdventureWorksAS sample Analysis Services database. These databases are used in the samples and in the code examples in the SQL Server 2005 Books Online.

Since its original release, new samples have been added for the following technologies: CLR, SMO, Integration Services, Replication, and Reporting Services. See the SQLServerDatabasesAndSamplesOverview.htm file for descriptions of the new and original samples.
