There are around seventy SQL Server instance settings, and a DBA needs to be aware of the effect that many of them have. Brad McGehee explains them in enough detail to help with most common configuration problems, and suggests some best practices.
At the last PASS summit, we cornered SQL Server MVP Glenn Berry, and found out his views on the impact of virtualization, solid state disks and SAN administrators on the life of a DBA, and what led him to write a book all about SQL Server Hardware.
This Friday Steve Jones wants to know if you are using encryption in your production system and if so, how is it working? Can you handle DR situations?
The relational model was devised long before computer hardware was able to deliver an RDBMS that could deliver a fully normalized database with no performance deficit. Now, with reliable SSDs falling in price, we can reap the benefits, instead of getting distracted by NOSQL with its doubtful compromise of 'eventual consistency'.
Steve Jones comments on predictions that we will see new types of APIs coming in the future, especially data APIs.
This script leverages master.sys.server_principals and xp_logininfo to return accounts, domain groups, and members in a SQL Server admin fixed role.
Come see Brad McGehee, Grant Fritchey, Steve Jones, and more SQL Server speakers at the SQL Server Connections conference in Las Vegas this spring. Get away from the cold on Mar 26, 2011 and learn about the new version of SQL Server.
SQL Server 2008 R2 Integration Services offer a wide range of pre-built components, which deliver generic functionality commonly required when performing extraction, transformation, and loading tasks. While most of them are fairly straightforward to deploy in their basic form, typically there are refinements or caveats that should be taken into account as part of their implementation. This principle becomes quite evident when considering use cases of Sort transformation, which is the subject of this article.

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
