• .NET Common Language Runtime integration: This
means you can write stored procedures, functions, triggers,
user-defined types, and even new aggregates in any .NET
language.
• Native HTTP SOAP Access: This means that the
database server can serve up data via Web Services with no
additional middleware at all, not even an instance of IIS.
• New xml data type: You can store XML data natively
in its own column type now.
• XQuery support: SQL Server supports XQuery for
querying against XML data, including extensions that allow
XML DDL operations.
• Improved Error Handling: T-SQL now supports TRY-
CATCH blocks for modern error handling.
• DDL Triggers: You can set up triggers that fire
when CREATE, ALTER, or DROP statements are executed.
• Query Notifications: With query notifications, an
external application can request the database engine to
notify it when the data in a cached result set changes.
This can dramatically lessen the load from requerying.
• Failover clustering now extends to 8 nodes on 32-
bit systems, and 4 nodes on 64-bit systems.
• Database mirroring introduces a new reliability
model for hot standby on a database-by-database basis.
• Users now have acess to a database during a restore
operation, within certain limits. This helps get you up and
running faster after problems.
• Multiple Active Result Sets (MARS): SQL Server 2005
introduces the ability for multiple statements to return
result sets at the same time on a single connection.
