This sample is provided in conjunction with the MSDN Magazine article, "SQL Server 2000 and XML: Developing XML-Enabled Data Solutions for the Web." This article presents and compares five data access approaches, using a variety of technologies including ASP and ADO, XSLT, and DirectXML. Once built, the solutions are compared on the basis of their speed and efficiency.
If you are like most DBAs, you have probably implemented some type of hash function for some of your tables at one time or another. This article takes a look behind the scenes as to how the Identity property works.
This week Andy takes a look at a new product from Red-Gate that gives you even more options than you get with their SQL Compare and SQL Data Compare tools - now you can build your own. Add the features you always wanted. Build automated processes instead of using the GUI. It's an interesting product - read the review and then maybe even enter the contest to win a free copy.
The application scenario described here, an e-mail-based SQL update program, uses a simple data model; however, this solution will apply to any data model that you are working with. It will also eliminate the need for complex n-tier Internet applications and serves as a low maintenance solution for providing data access.
This white paper is a joint effort by Microsoft and Dell to demonstrate the scalability of SQL Server 2000 and Dell hardware.
SQL Server DBAs are often curious about the inner-workings of SQL Server. Indeed, it can save your job during disasters to know what's going on inside SQL Server. This article shows you how to use some of the SQL Server internal views to view some meta data about your servers.
Continuing with the Worst Practices Series: Steve Jones examines why encryption in the database is a bad idea.
Currently, Microsoft is accepting nominations for the 64-bit version of the SQL Server beta program, code named "Liberty." The Liberty beta program is slated to start in February 2002. Important: You must have access to 64-bit hardware running Windows LE to participate in the Liberty beta program. This beta does not install on 32-bit hardware. Before signing up for the beta, verify that you have access to the appropriate hardware.
SQL Profiler lets you log the results of a trace directly to a table, yet would you believe you can't save the trace as a script to do the exact same thing? Find out why and get some ideas on work arounds.

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
