Working with Datetime

Datetime data in SQL Server can be a little confusing to work with, especially as many front end languages do not combine the date and time into a single datatype. As a result, T-SQL is sometimes used to manipulate and convert datetime data into more useable formats. Author Leo Peysakhovich has written about some tricks that he uses to reformat and work with datetime data.

Compliance

The Sarbanes-Oxley act has become a four letter word to many IT people in the US. Thankfully I only had to deal with it for about 9 months before I left to go work on my own, but it was a long 9 months. Especially since I did half the work with JD Edwards and then did it again with Peoplesoft 🙁

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;
