Deleting Child Data Based Upon Criteria in the Parent Table

New Author! Thom's first article discusses the difficulties you encounter when your database doesn't support cascading deletes (or you've opted not to use it) and you need to delete data in a child table based upon a value in the parent table. Not exactly your run of the mill delete query. Take a look and please rate/comment the article!

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;
