I was at a customer this week (sorry, can't share who). I spent the day talking about Redgate Monitor and how it can help with query tuning, server management, and estate management. Through the day, the data pros at the company were sharing how they were managing hundreds of servers and several thousand databases. They […]

I recently came back from a trip to Las Vegas. I was privileged to be able to take part in the very first Fabric Community Conference. It was a great event, well attended. BUT... It was in Las Vegas. I am not a fan. First of all, Vegas is just far too noisy for me. […]

So, I messed up. In my calendar on Friday were the words, "Database Weekly." That's because I was supposed to put this editorial together and put out the Database Weekly. But I messed up. I was traveling on Friday. Not an excuse, but it's why I messed up. I'm sorry. However, what I did this […]

Last year I had the most wonderful opportunity. I took part in Data Relay, an event in the UK which tours several cities. Wonderful time, but not the focus here. The very first one was held at the National Museum of Computing at Bletchley Park. Without a doubt, you've heard of Alan Turing, Enigma, and […]

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
