Everyone should be aware that XML is supported in SQL Server 2000 and plays an integral part of not only SQL Server 2005, but all of the Windows family. IIS metadata, web services, etc. all involve XML. But do you know what XML is and how to work with it? Author Raj Vasant brings us a basic article on what XML is and how the documents are structured.
A Chief Financial Officer (CFO) was approached by the CEO and asked for an accounting of the company’s financial assets. The CFO gave a vague response indicating a lack of knowledge of the corporate bank accounts, had little idea what was in each account, and had no idea about the status of accounts receivable. The Board of Directors asked the CEO about the intended use of the corporate assets and were told “there is no plan for their use.” The CFO and the CEO were soon pursuing new personal interests.
Recently, I began a Data Modeling “Master Class” by asking participants to nominate the toughest challenges facing them in their professional work. Virtually all the responses were about “soft” or “political” issues: persuading project teams to include a data modeling phase, negotiating territory with database technicians, gaining access to business people, and, of course, staying employed. No mention of normalization, star schemas, time-dependent data, exploiting new DBMS features, choice of language or indeed anything remotely technical
The 2005 PASS Summit is coming up in September and this is the best place to learn about SQL Server 2005 in the US. Steve Jones gives you a few reasons and arguments for your boss to let you go.
SQL Server 2000 has indexed views, which can greatly improve database performance. However there are a number of restrictions on building the view, including the restriction against outer joins. So how can this work? New author Jean Charles Bulinckx brings us a technique that can help you get around this restriction.
Over the past few years, I’ve had the opportunity to discuss enterprise metadata to a wide variety of audiences and much of this conversation is captured in this “Best Practices” implementation framework. The model has evolved over the past few years as our program continues to do the same. Of course, this summary can only be a few pages long so the depth of the content here will be a tad shallow but you should be able to get the basics from the diagram and the description that follows. Figure 1 provides the new framework and the content follows to describe each section.
We've all been there: the project that never ends and no light at the end of the tunnel. Nothing is more disheartening to a developer, DBA or anyone else that may be on a project than a finish line that has no end in sight or worse yet, one that keeps moving. Agile and Scrum development methodologies aim to fix this problem and others by applying what will appear to be common sense after you engage in the methodology for a few projects. This article will get you acquainted with my now-favorite d
Build an application to extract a query's estimated execution cost from its XML showplan. Users can submit only those queries costing less than a predetermined threshold to a server running SQL Server 2005, thereby ensuring it is not overloaded with costly, long-running queries.
SQL Server 2000 is an extremely powerful and flexible development platform, but if the users mess up the data, there's nothing you can do. Protecting the integrity sometimes means severely limiting access to users. Roy Carlson brings us a technique using sp_makewebtask that you can easily use to provide users with some data without giving them query access.
I have never met Ken Henderson, but I have followed his career, read his books, and even reviewed one or two of them for Dr. Dobb’s Journal. When I first saw Ken’s The Guru’s Guide to Transact SQL I almost did not pick it up. As a general rule, I don’t pick up the guru’s guide to anything. I’m glad I overcame this, since the book is little short of amazing.
Ken surprised me again with his latest book, The Guru’s Guide to SQL Server Architecture and Internals . About 400 pages into it, I was impressed by the introduction to what is involved in creating a server-based application, but wondered about its inclusion in a SQL Server book. The next 400 pages made it clear that understanding how servers work on Windows is critical to understanding the implications of how SQL Server runs.

I have some data in a table:
CREATE TABLE #test_data
(
id INT PRIMARY KEY,
name VARCHAR(100),
birth_date DATE
);
-- Step 2: Insert rows
INSERT INTO #test_data
VALUES
(1, 'Olivia', '2025-01-05'),
(2, 'Emma', '2025-03-02'),
(3, 'Liam', '2025-11-15'),
(4, 'Noah', '2025-12-22');
If I run this query, how many rows are returned?
SELECT t1.[key] AS row,
t2.*
FROM OPENJSON(
(
SELECT t.* FROM #test_data AS t FOR JSON PATH
)
) t1
CROSS APPLY OPENJSON(t1.value) t2; See possible answers
