Working with Time Spans and Durations in SQL Server
What is the best way to return the "duration" of an event in SQL, given the start and end datetime values? How can we add up these durations to return grand totals? What data types should be used to return this data to our clients? How do we handle overflows, such as when hours go over 23 or minutes total up to over 59? Are there any T-SQL functions or other techniques that are useful in these scenarios?

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; See possible answers
