SQL Server Express Features
SQL Server 2008 Express is based on SQL Server, and supports most of the Database Engine features of that product.
If you create and design a database in SQL Server Express, you can migrate this database to SQL Server. However, you will not be able to use the SQL Server Express database together with earlier versions of SQL Server. This includes SQL Server 2000.
SQL Server Express supports most of the features and functionality of SQL Server. The following table lists some of the major features and components that are supported.
SQL Server Configuration Manager
Replication (as a subscriber only)
Advanced Query Optimizer
sqlcmd and osql utilities
Integration with Visual Studio 2005
Snapshot Isolation Levels
Service Broker (as a client only)¹
Native XML support, including XQuery and XML Schemas
Transact-SQL language support
Multiple Active Result Sets (MARS)
Dedicated Administrator Connection²
¹ SQL Server Express supports Service Broker, but direct communication between two SQL Server Express servers is not supported.
² The Dedicated Administrator Connection feature for SQL Server Express is supported with the trace flag 7806. For more information on trace flags and Dedicated Administrator Connection, and Using a Dedicated Administrator Connection in SQL Server Books Online.
During setup of SQL Server Express a login is added for the BUILTIN\Users group. This allows all authenticated users of the computer to access the instance of SQL Server Express as a member of the public role. The BUILTIN\Users login can be safely removed to restrict Database Engine access to computer users who have individual logins or are members of other Windows groups with logins.
