My name is Kamil Nowinski and I'm the founder & owner of SQLPlayer blog.
I'm Microsoft Data Platform MVP, MCSE. Senior Data Engineer, data geek and friend of Redgate. I speak at user groups and conferences across Europe. Love #SQLfamily and Community around Microsoft Data Platform - that's why my podcast is called "Ask SQL Family" where I talk to well-known and valued specialists in the industry (including Microsoft employees).

Question of the Day

Fun with JSON I

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 *
FROM OPENJSON(
     (
         SELECT t.* FROM #test_data AS t FOR JSON PATH
     )
             ) t;
