Today and tomorrow, as I write this, the Green Country Hamfest will be running up in Claremore, OK. Tomorrow morning, I'll be there to check out the tables and maybe pick up some new radio gear. I'll also be volunteering to help run the doors. Largely it involves just checking to be sure people paid […]

I honestly enjoy writing editorials. Something pops into my tiny brain next to something else, and I'm off. However, today, as I started to write on the topic of learning, I suddenly felt like I had just written this same editorial. I go and look, sure enough, several of my recent editorials have been on […]

Yesterday, I had the opportunity, and the privilege, to attend an all-day workshop put on by Bob Ward teaching all about SQL Server 2022 (you can take this too, Bob is presenting it at SQLSaturday Austin and SQL Bits, and there will be more). It was a great day. Bob is an excellent teacher. Even […]

I am an amateur radio operator. In the US this is commonly referred to as a ham, or a ham radio operator. My call sign is KC1KCE, as issued by the US government through the FCC. And yeah, I can hear you now, a ham is the geek equivalent of a cross-fitter. How do you […]

Happy New Year! You're going to be seeing a lot of summaries for 2022 and predictions for 2023 around this time of year. I'm not writing one of those. You'll also see people calling for new years resolutions and the like. I'm not going for that either. Nope, let's keep it simple. It is a […]

If you're an experienced, knowledgeable, seasoned (I won't say old), SQL Server data professional, and you choose to use Trace Events (Profiler), more power to you. That's it. That's all I have to say. Do what you think best. I'm never, ever (again), going to second guess you. Further, my apologies for ever having done […]

On nights and weekends, I've been playing with Arduino controllers. I have a couple of projects I'm working through (building a robot that can roll around with "eyes" to avoid obstacles). I've also been trying to work with STM32 controllers, because in a lot of ways, they're more powerful than an Arduino. However, I've hit […]

I was sitting here thinking about the editorial when Kathi Kellenberger came to mind. She would frequently write about her favorite show, Star Trek. I too have been a fan of Star Trek since I was very young. However, my favorite show is a little more obscure and not as many people have seen it, […]

I have several things I’d like to say in the editorial today, but I feel I have to start off with my condolences to the family of Queen Elizabeth II. For that matter, my condolences to the people of Britain. This truly is the end of an era. Things do indeed move fast sometimes. Working […]

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
