This trigger will work even if you don't have the primary key on any table. Mechanism to configure the primary key in config table has been provided. This can be very helpful to solve the system audit requirements without much efforts.
Disclaimer : Audit Log trigger has performance overhead. It’s meant for table which is not frequently updated, deleted or inserted. Please take precaution when creating the trigger on the table having too many columns.

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
