What’s New for You in SP2?
by Brian Moran, [email protected]
Last week, Microsoft announced the release to manufacturing (RTM) of the 2007 Microsoft Office system, SQL Server 2005 Compact Edition Release Candidate 1 (RC1), and a Community Technology Preview (CTP) for SQL Server 2005 Service Pack 2 (SP2). It was a busy week. I’ve discussed the implications of the 2007 Office release on the SQL Server world a number of times, and I’ll be revisiting this topic in the near future now that the 2007 Office system is available. I’ll also be discussing SQL Server Compact Edition in an upcoming editorial. But this week, let’s chat about the SQL Server 2005 SP2 CTP.
You can download the CTP from http://www.microsoft.com/sql/ctp.mspx. What do you do with a CTP? Microsoft advises and encourages customers to experiment with the CTP in a way that lets them provide feedback that Microsoft can incorporate into the final SP2 release. Should you use this CTP in production? I hope you know the answer is no. Microsoft further clarifies with this advice: “As with all CTPs, we do not advise putting them into production because Microsoft does not provide support for these pre-release versions. However, we do recommend that customers download the CTPs, use them in a test environment and provide feedback so we can improve the final release. The exceptions are the customers in our Technology Adoption Program (TAP). Microsoft provides additional support to these customers to find out how the bits run in a real world environment.”
What are some of the most significant enhancements in SP2? Make sure to check out the Microsoft Web site for complete details, but some of the most significant enhancements include:
- support for the pending release of Windows Vista
- data-mining add-ins for the 2007 Office system
- Oracle support in Report Builder, which lets you use Report Builder directly on top of Oracle data sources
- SQL Server Reporting Services support for Hyperion
- a new type of data compression, implemented by means of a new data type called varDecimal, which has practical performance-enhancement implications for such implementations as large data warehouses and SAP environments
- numerous manageability enhancements that include maintenance plans, management reports, and a new-and-improved copy-database wizard
- the addition of management reports for SQL Server Express and new support that lets SQL Server Management Studio Express Edition manage SQL Server Compact Edition databases
When will the final bits for SP2 become available? Microsoft says that SQL Server 2005 SP2 should be released after the launch of Windows Vista, which is still on track for delivery in the first quarter of 2007. Enjoy.

2. SQL Server Watch
Product Milestones Benefit Information Workers, IT Pros and Developers
Yesterday at the Professional Association for SQL Server (PASS) Community Summit in Seattle, Microsoft Senior Vice President of Server Applications Paul Flessner delivered a keynote address that highlighted several product milestones related to Microsoft’s data platform. Flessner particularly noted the availability of the Community Technology Preview (CTP) of Service Pack 2 (SP2) for SQL Server 2005, which delivers key updates including data compression, increased business intelligence (BI) functionality, manageability enhancements, support for Windows Vista, optimization for the 2007 Office system, and security updates relating to Common Criteria. Flessner explained that customers have given Microsoft feedback that they want security assurances, so the company is pursuing Common Criteria certification on the Enterprise Edition of both SQL Server 2005 SP1 and SP2. Common Criteria evaluation is a procurement requirement of many governments and a preference for several industries and customers.
Flessner also announced the Release Candidate (RC) of SQL Server 2005 Compact Edition, a new offering for essential relational database functionality in a compact footprint. SQL Server Compact Edition (formerly dubbed SQL Server Everywhere Edition) lets developers and administrators use their existing skills and be immediately productive while building and supporting the next generation of applications.
A major announcement for the database developers in the crowd was the release to manufacture (RTM) date for Visual Studio Team Edition for Database Professionals (Team Data), which has been set for November 30, 2006. Team Data provides a foundation for change management, development, testing, and deployment of databases through integrated functionality that lets database developers and administrators be more productive, reduce risk, and improve quality.
In addition, Flessner highlighted plans to provide process guidance for database professionals included in the Microsoft Solutions Framework. This process guidance demonstrates Microsoft’s commitment to making the database professional a full-fledged participant in the application lifecycle.
You can download the SQL Server 2005 SP2 CTP at http://www.microsoft.com/sql/ctp.mspx , download SQL Server Compact Edition RC1 at http://www.microsoft.com/downloads/details.aspx?familyid=85e0c3ce-3fa1-453a-8ce9-af6ca20946c3&displaylang=en, and get more information about Team Data at httphttp://msdn2.microsoft.com/en-us/teamsystem/aa718807.aspx.
Focus: SQL Server Management Tools: Where Do I Find It in SQL Server 2005?
Lost in the maze of new SQL Server 2005 features and interfaces? Here’s how to find some of your favorite tools.
by Blake Eno, [email protected]
Identify Bottlenecks in SQL Server or Oracle Databases
Confio Software announced Ignite for SQL Server, a performance-monitoring tool for SQL Server 2005 and 2000 databases that works alongside its current Ignite for Oracle solution to provide a common platform to monitor databases on both platforms. Ignite for SQL Server uses a wait-time-based approach, which measures the time impact of bottlenecks inside the database and correlates them with the end-user application service. This analysis helps to instantly identify the exact SQL and database process that's creating the most delay for end users. Ignite Alerts provide advance notice of accumulating bottlenecks on screen or through email, cell phone, or pager messages. Ignite for SQL Server is also agentless, letting you capture performance data without installing agents on production systems. For more information, contact Confio Software at 303-938-8282 or 866-266-3461 or visit http://www.confio.com.
Manage SQL Server and Oracle Scheduled Events
SQL Sentry announced that SQL Sentry Event Manager, which helps DBAs manage scheduled events, now supports Oracle, letting you manage SQL Server, Windows Task Scheduler, and Oracle in the same platform. Event Manager for Oracle Enterprise Edition (EE) functionality includes visual schedule management, performance monitoring, alerting and response actions, graphical reporting, and advanced chaining. Event Manager automates a logical workflow between SQL Server and Oracle, and the product’s interface provides insight over all scheduled database events, regardless of platform. For more information, contact SQL Sentry at 704-895-6241 or [email protected] or visit http://www.sqlsentry.net.

December Reader Challenge
Now, test your SQL Server savvy in the December Reader Challenge, "Improve T-SQL to Prevent Deadlocks" (below). Submit your solution in an email message to [email protected] by November 22. Umachandar Jayachandran, a SQL Server Magazine technical editor, will evaluate the responses. We'll announce the winner in an upcoming SQL Server Magazine UPDATE. The first-place winner will receive $100, and the second-place winner will receive $50.
Here's the challenge:
Manoj is a database developer for a company that develops business applications that use SQL Server 2000 as a database server. In Manoj's environment, the database that the applications use contains a table that stores sequential numbers used by various features. The table stores the name of the sequence and the next number. The schema of the table is shown in the following code:
USE tempdb GO CREATE TABLE dbo.Sequences ( SeqName varchar(30) NOT NULL PRIMARY KEY, NextNum bigint NOT NULL DEFAULT 0) INSERT INTO dbo.Sequences (SeqName, NextNum) VALUES( 'Sequence #1', DEFAULT ) INSERT INTO dbo.Sequences (SeqName, NextNum) VALUES( 'Sequence #2', DEFAULT ) INSERT INTO dbo.Sequences (SeqName, NextNum) VALUES( 'Sequence #3', DEFAULT ) GO
The database also contains a GetNextSeqNum stored procedure, which the applications use to get the next number in a particular sequence. The stored procedure is shown in the following code:
USE tempdb GO CREATE PROCEDURE dbo.GetNextSeqNum (@SeqName varchar(30), @NextNum bigint = NULL OUTPUT) AS BEGIN BEGIN TRANSACTION SET @NextNum = (SELECT NextNum FROM dbo.Sequences WHERE SeqName = @SeqName) UPDATE dbo.Sequences SET NextNum = NextNum + 1 WHERE SeqName = @SeqName COMMIT TRANSACTION END GO
When Manoj tests the stored procedure with concurrent SQL Server connections, he notices that some of the calls encounter deadlocks and fail. Modify the stored procedure logic to help Manoj resolve the deadlock problem.
