How to Resize tempdb
When you are setting up a new SQL Server machine you need to determine how big you should make tempdb. To make sure you size tempdb appropriately you should monitor the tempdb space usage. If there are autogrowth events occurring after you have recycled SQL Server than you might want to increase the size of your tempdb data files. If tempdb never uses most of the tempdb space, then you might want to consider decreasing the size of tempdb.

Question of the Day
Fun with JSON II
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
