SQL Server Training: 2009 Conferences

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.

SQL Server CLR function to concatenate values in a column

If a column is normalized, but the user really wants to see the values as a short comma separated list, how can I write a query that produces the list? Concatenating the values in a column would be pretty easy if SQL Server had a concatenate aggregate function, which it doesn't. What's more, for efficiency sake it's important to write the reporting queries without using cursors.

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;
