Leaving aside, for a second, Freud’s psychoanalytical definitions, the term “ego” generally refers to a person’s sense of self, and their self-esteem. In casual usage, however, it usually appears in the adjectival form, “egotistical” (most often followed by “jerk”). You don’t need to be a jerk to be a DBA; humility is important. However, ego is important […]

Of all the valuable attributes of a DBA, from passion to humility to practicality, perhaps one of the most important attributes may turn out to be the most seemingly nebulous: foresight. According to Free Dictionary, foresight is the "perception of the significance and nature of events before they have occurred". Foresight does not come naturally to most people, as the […]

I started in the early days of SQL Server, when having a gigabyte of disk storage was unheard of, much less a gigabyte of RAM.

These persons who have trained to analyze data using complex math formulas […]

Recently, as I was doing some work for the upcoming PASS Summit, a question popped in my head: “Why am I doing this?” It reminded me of the time when I was young (and idealistic). I went to the leader of a non-profit group asked about making it my permanent vocation. The leader looked at […]

One of the greatest things that has arisen in the past 10 years or so is a veritable stream of great conferences for people to learn how to write better software, many of them low cost or even free. In the Data Platform community, we have had nearly 800 free SQL Saturday events around the […]

In order to be great, you need to have an idea what great is. A quote I use in every one of my database design presentations is by one of my non-technical inspirations, C. S. Lewis. The quote is from his book, An Experiment in Criticism. “There are no variations except for those who know […]

I hate deadlines. Really. I truly hate them. The problem is: they are usually unrealistic, often not much more than a wild guess. They restrict the amount of time that I can spend in preparation and research so that I can do things right; they squeeze the artistic quality out of my work as a […]

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
