Started working with databases in 1984. Clients have kept pushing me into front end programming over the years, giving me a widely varied background in VB, ASP, HTC, SQL, DHTML, COM, RPG, Cobol, Fortran (how many people know what .HTC is anymore...grin). I've worked with SQL Server in particular since version 4.2 was released. I've worked with DB2, AS\400's, Sybase, Oracle, Informix, Alpha4 & 5, Access (all versions to date.) (Boy, I almost didn't even mention that one.), and a lot of databases which people still debate as to whether they were even databases or not. Hold a lot of different certificates I got before I realized how little they matter.

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;
