Stairway to SQL Server Security

Stairway to SQL Server Security Level 4: Permissions

A permission gives a principal access to an object to perform certain actions on or with the object. SQL Server has a mind-numbingly huge number of permissions that you can grant to a principal, and you can even deny or revoke those permissions. This sounds a bit complicated, but by the end of this stairway level you’ll understand how SQL Server permissions work and how you can exert very granular control over object creation, data access, and other types of actions on database and server objects.

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;
