Pablo Echeverria

I've worked for more than 10 years as a software programmer and analyst, during which time I studied parallel programming and became a senior programmer specialist. In 2016, I switched jobs to a DBA position, where I've implemented new processes and created better monitoring tools, while I'm growing my data scientist skills to improve my customer's businesses.

Check out Pablo's most recent book https://bpbonline.com/products/hands-on-data-virtualization-with-polybase. This book brings exciting coverage on establishing and managing data virtualization using Polybase. This book teaches how to configure Polybase on almost all relational and nonrelational databases. You will learn to setup a test environment for any tool or software instantly without any hassle. You will learn how rapidly to design and build high performing data warehousing solutions.

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;
