Being a DBA demands that you keep up with the latest technology, and conferences are one of the best ways to do that. So, despite the fact that training budgets may be shrinking, I suggest you begin lobbying your manager to attend as many SQL Server events as you can. If you can't get your company to send you to a paid conference, then try to attend one of the free ones, on your own time.

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
