In Yukon, the next major release of SQL Server, Microsoft is introducing several new technologies that will change the types of skills that traditional DBAs need. Although Yukon's commercial release is still almost a year away, it's time to start thinking about Yukon and preparing for the changes if you haven't already done so.
Yukon's introduction of native support for the .NET Common Language Runtime (CLR) and richer XML integration will force hard-core DBAs to learn more about the development world than they've had to in the past. Ignoring these new technologies will relegate you to the DBA dinosaur heap within a few years. The advent of .NET integration in Yukon doesn't mean that the DBA's role is about to expire, but it does mean that the tasks a DBA must master to stay current are about to expand.
You can start educating yourself by visiting Microsoft's Yukon home page at http://www.microsoft.com/sql/yukon/productinfo/default.asp . The site provides many interesting technical resources, including Microsoft's list of top 30 Yukon features. The page also includes several valuable technical articles, including:
- Overview of .NET Programming Features in SQL Server "Yukon" Beta 1
- Performance Optimizations for XML Data Type
- SQL Server "Yukon" Beta 1 Transact-SQL Enhancements
- XML Best Practices for SQL Server "Yukon"
- Introduction to SQL Server "Yukon" Relational Engine Security Features
- Reporting Services Beta Deployment Guide
A quick Internet search will reveal more Yukon information, including the following articles from SQL Server Magazine's special November Yukon coverage:
- "Exploring Yukon Territory"
- "Ready or Not, Here Comes the CLR"
- "What's New in Yukon T-SQL"
- "Top Yukon Features"
Articles and white papers give you useful information, but they don't let you get your hands dirty with the real thing. By now, you're probably wondering, "Where's the beef?" To start thinking about Yukon in a serious way, you want access to Yukon Beta 1.
Microsoft is managing Yukon's beta process in an interesting way. The company distributed more than 10,000 copies of Yukon Beta 1, considered a private beta, at the recent Professional Developers Conference (PDC) and Professional Association for SQL Server (PASS) meeting. Attendees at these conferences weren't under a nondisclosure agreement (NDA), so the beta kits that Microsoft handed out are distributable if you have colleagues or friends who attended one of those events. However, Microsoft hasn't made a version of Yukon Beta 1 publicly downloadable. You can sign up for the next Yukon beta at http://www.microsoft.com/sql/evaluation/betanominations.asp and expect a widely distributed public beta sometime next year. Given the number of copies distributed at PASS and PDC, you shouldn't have too much trouble getting your hands on the beta kit. In the meantime, you can explore SQL Server Magazine's Yukon beta forum at http://lists.sqlmag.com/cgi-bin3/DM/y/edq20FgQMn0BRZ0KQO0A3 for valuable information and ask questions of those currently evaluating the beta.
Don't worry. I'm not going to harp incessantly about Yukon over the coming months. After all, many of us will be focused on current SQL Server installations for at least the next year, and SQL Server 2000 is sure to have a wide user base for years to come. However, the major changes coming with Yukon will require you to start educating yourself sooner rather than later.
POLYSERVE MATRIX SERVER CLUSTERING SOFTWARE
Easily consolidate SQL Servers and storage. The first high availability, shared data clustering solution that helps you consolidate and centrally manage SQL Servers, eliminate data silos, and reduce TCO 50 percent.

2. SQL SERVER NEWS AND VIEWS
Microsoft has released a hotfix for a problem in which distributed queries using a linked server might incorrectly use the SQL Server startup account to connect to the linked server instead of using the configured linked server account. This problem might occur when both of the following conditions exist:
- SQL Server is running in fiber mode (i.e., the sp_configure stored procedure lightweight pooling option is set to 1).
- The distributed query is executed by a Windows NT login and the linked server security is configured to use the login's current security context option.
To read more about this problem and obtain the fix, see the Microsoft article "FIX: Distributed Queries May Incorrectly Use SQL Server Startup Account Permissions When SQL Server is Running in Fiber Mode" at http://support.microsoft.com/?kbid=830382.

ANSI SQL defines three operations—UNION, INTERSECT, and EXCEPT—that you can apply to two sets.
These operations let you combine rows from different sets, locate which rows
exist in both input sets, or find which rows exist in one set but not the
other. However, T-SQL supports only the UNION operation. Fortunately, you have
alternatives in T-SQL that you can use to provide the functionality of the
missing operations. In his December T-SQL Black Belt column,
"Set-Operation Alternatives," Itzik Ben-Gan shows you how to mimic
INTERSECT and EXCEPT in T-SQL.
Mpp wonders if you need a thorough understanding of Microsoft .NET to fully take advantage of SQL Server's upcoming Yukon release. See what other people have said and offer your advice on SQL Server Magazine's Yukon forum at

Q. I want to run a query from Enterprise Manager, but it times out at 30 seconds, generating the following message:
SQL Server Enterprise Manager \[Microsoft\]\[ODBC SQL Server Driver\] Timeout expired
I've tried to change the Query timeout option from the Tools, Options, Advanced dialog box, but the option doesn't have any effect. How can I get my query running?
A. I assume you're trying to run a query that you created through the Graphical Query Designer, available from the Query option on the Open Table menu within Enterprise Manager. Unfortunately, the timeout is hard-coded to 30 seconds for queries running from that interface, and you can't override the default timeout value. You can still use the Graphical Query Designer to build the query if you aren't comfortable with T-SQL, then simply copy the query into Query Analyzer to run it. You can control the query timeout setting in Query Analyzer's Options menu.

6. NEW AND IMPROVED
(contributed by Dawn Cyr, [email protected])
Sql Power Tools announced the Stealth Blocked Process Monitor, software that lets DBAs and
developers accurately monitor and detect blocked SQL statements. When a block
occurs, the product shows the associated SQL text, plan description, database
locks involved in the block, resource utilization, and the length of time the
SQL statement was blocked. The software also maintains a history of blocks and
pinpoints and ranks SQL statements that are most frequently involved in
blocking so that you can solve your most common blocking problems. For more
information and pricing, contact Sql Power Tools at [email protected]
Quest Software announced Quest Central for Databases 4.0, software that lets you automate
database administration, performance diagnostics, tuning, application testing,
and space management across heterogeneous database platforms. The product's
latest version supports SQL Server, so DBAs can manage their SQL Server
databases along with databases on Oracle and IBM DB2 through one central
console. The product also includes a built-in Knowledge Base for each database
environment and an automated tuning methodology to help streamline performance
management. Pricing for Quest Central for Databases 4.0 starts at $1500. For
more information, contact Quest Software.
