This article proposes a system where extra data is stored in a simple row based table and retrieved using the 'store key'. It's not a new concept of course, but the author explains how and why he chose to implement. Feedback should be interesting!

This article shows how to do conditional multiple table inserts. While it is more script than we typically display, it's interesting and might get you thinking about other uses for the idea.

This articles proposes storing the source code for stored procedures on disk rather than in the database itself, the intent to give developers the ability to easily change them or potentially to allow third party encryption of source code. (Note from SSC: If you choose to implement a technique like this, please be sure you understand the implications of exec'ing strings)

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
