1. COMMENTARY
- SQL SERVER SHINES IN DATABASE MARKET REPORT
- (contributed by Brian Moran, news editor, [email protected])
Gartner recently released its summary of 2001 relational database management system (RDBMS) market share and revenue numbers. Many of the trends are similar to those the research company reported last year, which I wrote about in "Database Wars Heat Up"
http://www.sqlmag.com/articles/index.cfm?articleid=21431 ).I encourage you to read the Gartner report, "DBMS Software Market: Flat but Not Calm," which is available free at http://www.gartner.com/reprints/microsoft/106576.html. The article is only three pages long and contains detailed breakdowns of DBMS market share and revenue numbers for 2000 and 2001 for all major vendors. Here are some interesting points I observed about this data.
- The Windows platform is the unquestionable sweet spot in the database market. The Windows RDBMS market grew overall by 11 percent, whereas the UNIX RDBMS market shrunk overall by 1.4 percent. At this rate, the total worldwide market for Windows-based RDBMSs will be within less than 10 percent of the total market for UNIX-based RBDMSs within 1 year and new Windows-based RDBMS sales will exceed UNIX sales in less than 2 years.
- IBM and Microsoft are both doing well, whereas Oracle's fortunes seem to be declining. IBM's 2001 market share increased by a respectable 6.2 percent. Microsoft's 2001 market share increased by an amazing 25.3 percent. Oracle's 2001 market share shrunk by 4.9 percent.
- SQL Server has finally become the dominant RDBMS on the Windows OS in terms of revenue and is the only Windows RDBMS platform with more than $1 billion in revenue. SQL Server claims 39.9 percent of the Windows RDBMS market, which is almost 6 percent higher than Oracle and is almost double IBM's third-place finish. In other words, SQL Server is the leading RDBMS on the world's fastest-growing RDBMS platform.
What accounted for SQL Server's rapid growth in an otherwise tepid market? Sheryl Tullis, SQL Server product manager, said, "Customers are deploying their new projects on SQL Server 2000 because it's a data management and analysis platform—not just a database like our competitors offer. Customers see the value of the integrated BI and development tools, low cost of ownership, and tight integration with the .NET platform."
The Gartner report's findings probably won't surprise anyone. These trends have been developing for several years, and I predicted their acceleration in my market share commentary last year when I wrote: "Windows RDBMS growth will accelerate while growth on the UNIX platform slows. Why? Because dot-com implosions have made people much more careful about how they spend their money, and Windows RDBMS solutions tend to be more cost-effective than UNIX solutions."
Those market dynamics haven't changed, and I expect both the SQL Server and Windows RDBMS markets to continue to grow rapidly while the UNIX RDBMS market continues to contract.
CORRECTION: In my May 16 SQL Server Magazine UPDATE commentary "Staying Ahead in the Security Game" ( http://www.sqlmag.com/articles/index.cfm?articleid=25248), I stated that you need to apply the patch in Microsoft Security Bulletin MS02-020 (SQL Extended Procedure Functions Contain Unchecked Buffers) to SQL Server 2000 Service Pack 2 (SP2) and SQL Server 7.0 SP4. However, SQL Server 7.0 SP4 includes the patch. So, you need to apply the patch only if you're running SQL Server 7.0 SP3 or earlier. You don't need to apply the patch if you're running SQL Server 7.0 SP4.

2. SQL SERVER NEWS AND VIEWS
- Spida Worm Infects SQL Server SYSTEMs
(contributed by Mark Joseph Edwards) - SQL Server DBAs can apply third-party software or review their system settings to guard against the Spida worm, which affects SQL Server systems. Spida, first detected last week, infects SQL Server machines that have a blank systems administrator (sa) account password. The worm's primary action is to obtain a copy of the system's SAM database, which stores sensitive account information such as usernames and password hashes, and email the database to a recipient. The worm is written in JavaScript, batch files, and compiled executables and contains a scanner that searches for other SQL systems to infect. The scanner can create large amounts of network traffic because it can spawn up to 100 threads during its scanning operations.
Antivirus software vendors have updates available to clean the worm from infected systems. Networks with firewalls that guard against intrusion to SQL Server machines (port 1433) are protected against infection from external systems. Users need to check that their SQL Server systems don't have blank passwords related to any user account, including the sa account. In addition, Microsoft has an online document that helps users secure their SQL Server installations. Users need to review the document for any relevant configuration settings that might help protect their systems. The online document is available at http://www.microsoft.com/sql/techinfo/administration/2000/security.asp.
- RESULTS OF PREVIOUS INSTANT POLL: SQL SERVER SECURITY
- The voting has closed in SQL Server Magazine's nonscientific Instant Poll for the question, "Do you spend more or less time managing SQL Server security protocols than you did two years ago?" Here are the results (+/- 1 percent) from the 130 votes:

- 35% Somewhat more time
- 22% About the same amount of time
- 12% Less time
- 15% Don't know or doesn't apply
- NEW INSTANT POLL: RDBMSs IN USE
- The next Instant Poll question is, "Which relational database management systems (RDBMSs) are in use at your company?" Go to the SQL Server Magazine Web site and submit your vote for 1) SQL Server, 2) Oracle and SQL Server, 3) DB2 and SQL Server, 4) Oracle, DB2, and SQL Server, or 5) Other.

- WHAT'S NEW IN SQL SERVER MAGAZINE: THE DATA IS JOB ONE
- Protecting and managing corporate data is a DBA's top priority. In "The Data Is Job One," Michael Otey encourages readers to avoid getting sidetracked by day-to-day troubleshooting problems that might undermine responsible data-management practices. The article appears in the June 2002 issue of SQL Server Magazine and is available online at the following URL:

http://www.sqlmag.com/forums/messageview.cfm?catid=8&threadid=6416 - TIP: APPENDING AN IDENTITY COLUMN TO A TEMPORARY TABLE
- (contributed by the Microsoft SQL Server development team)
Q. I want to append an IDENTITY column to the temporary table that the following SELECT INTO statement returns:
SELECT * INTO #tmp FROM Products ALTER TABLE ADD columned INT IDENTITY
Although I currently use ALTER TABLE, I suspect I'm making the query more complicated than I need to. How can I append the IDENTITY column another way?
A. We don't recommend using ALTER TABLE to append an IDENTITY column because it logs an update on a row-by-row basis. And in the absence of the appropriate fill factor, ALTER TABLE also causes page splits. Using SELECT INTO with the IDENTITY(type, seed, increment) clause is a more efficient method because SQL Server has to pass through the data only once and SELECT INTO uses the FAST BULK LOAD APIs to copy the data. To see an example of how to use SELECT INTO with the IDENTITY clause and a Bulk-Logged Recovery model to ensure minimal logging, click Listing 2 in the online version of the article "Appending an IDENTITY Column to a Temporary Table" at the following URL:
