Roland Alexander was an application developer for the first half of his 20+ year career in IT – then he came over to the Dark Side of SQL Server development, and is now diving headfirst into the deep end of the DBA pool. This blog is about his observations, discoveries, trials, and tribulations, and he hopes you enjoy reading it, learn a thing or two, and (hopefully) teach him a thing or two while you’re at it.

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;
