Required Reading: SQL Server 2005 Security Changes
by Brian Moran, [email protected]
Sexy, exotic new SQL Server 2005 features such as the SQLCLR, Service Broker, endpoints, and SQL Server Integration Services (SSIS) have gotten a lot of press time. However, core security-model changes are some of the most important changes in the product—and they seem to have been a bit under-reviewed during the upgrade cycle. My space in this editorial is limited, so, I'm not going to dive deep into the specifics of what's changed. But you need to realize that the security model has undergone changes that you must understand before moving your SQL Server 2000 applications to SQL Server 2005.
The SQL Server 2000 security model didn't get a big name change (e.g., DTS to SSIS), but the SQL Server 2005 security model is different from SQL Server 2000 in many core ways. DBAs who are upgrading to SQL Server 2005 can choose to disable the SQLCLR or other new features until they better understand them. But you can't disable security, and you certainly need to be familiar with the changes before moving to production.
The SQL Server 2000 security model is pretty simple. We have logins, users, roles, and a relatively limited number of base permissions. SQL Server 2005 adds the key security model concepts of Principals and Securables, and the base permission list has grown to almost 200 distinct permissions. Granting a user some of these permissions in turn also grants the user derived or implicit access to other permissions. Thus, it's important to review the changes so that you thoroughly understand the relationships among permissions.
Other changes will also spark your interest and get you digging deeper into the security changes. For example, SQL Server 2000 had the concept of a schema as it related to object ownership and definition, but do you know that schemas in SQL Server 2005 are vastly different? And do you know that the EXECUTE AS statement gives you a way to manage security of dynamic T-SQL within a stored procedure?
You can review a comprehensive set of the changes directly from the SQL Server 2005 Books Online (BOL) topic "Security Considerations for Databases and Database Applications" at http://msdn2.microsoft.com/en-us/library/ms187648.aspx. If you want more information, a 15-second Internet search will yield a rich collection of other resources about SQL Server 2005 security.
A typical DBA can get by without knowing many of the newest SQL Server 2005 features during the early phases of an upgrade. However, no DBA can run the risk of making a serious error by not being familiar with the security changes in SQL Server 2005.

Microsoft Announces Plans for Summer CTP of SQL Server Everywhere Edition
Today, Microsoft announced plans for a summer Consumer Technology Preview (CTP) release of its new SQL Server Everywhere Edition. The new offering will specifically promote building client applications that operate in "occasionally connected" environments. The new edition, which shares a common programming model with all other SQL Server editions, will provide a "lightweight, compact, but rich subset of the capabilities found in other SQL Server editions. Beyond having rich local data management capabilities, SQL Server Everywhere Edition will also include support for seamlessly synchronizing with other SQL Server editions," according to Paul Flessner, Microsoft Senior Vice President for the Data and Storage Platform Division. The company plans a final release of SQL Server Everywhere Edition before the end of the calendar year.
The announcement of the new SQL Server edition comes as part of a general public announcement in which Flessner detailed Microsoft's plans for significant investment in its data-management products. Central to Microsoft's data-management vision, dubbed "Your Data, Any Place, Any Time," are what Flessner calls SQL Server AlwaysOn Technologies. These technologies--such as SQL Server 2005's database mirroring, failover clustering, database snapshots, and enhanced online operations—let customers achieve and maintain high application availability. Flessner's announcement stresses that such technologies will continue to be enhanced in upcoming SQL Server releases, which Microsoft has committed to providing every 24 to 36 months. You can read Flessner's complete update at http://www.microsoft.com/sql/letter.mspx.

Hot Tip:
How Not to Use USE
by Microsoft's SQL Server Development Team, [email protected]
USE is not a T-SQL statement like GO; only tools such as ISQL, OSQL, SQLCMD, Query Analyzer, and SQL Server 2005 Management Studio understand it. Here's a T-SQL procedure that doesn't use USE to retrieve table information from databases.
