With the rise of NoSQL databases that are exploiting aspects of SQL for querying, and are embracing full transactionality, is there a danger of the data-document model's hierarchical nature causing a fundamental conflict with relational theory? We asked our relational expert, Hugh Bin-Haad to expound a difficult area for database theorists.

As well as its multidimensional model, SQL Server Analysis Services (SSAS) now has a tabular model of database that either runs in-memory or in DirectQuery mode. The in-memory analytics engine allows the users of Excel or Power View to base reports on tabular model objects. Having shown how to handle date-based information using the Multi-dimensional model, Dennes now turns his attention on the in-memory tabular model.

To be able to make full use of the system catalog to find out more about a database, you need to be familiar with the metadata functions. They save a great deal of time and typing when querying the metadata. Once you get the hang of these functions, the system catalog suddenly seems simple to use, as Robert Sheldon demonstrates in this article.

When your SQL Server database is set to have its statistics automatically updated, you will probably conclude that, whenever the distribution statistics are out-of-date, they will be updated before the next query is executed against that index or table. Curiously, this isn't always the case. What actually happens is that the statistics only gets updated if needed by the query optimiser to determine an effective query plan.

The purpose of a database build is simple: prove that what you have in version control can successfully create a working database, and yet many teams struggle with unreliable and untested database build processes that slow down deployments and prevent the delivery of new functionality. Grant Fritchey explains how to achieve an automated and reliable database build that is only as complex as the database system it needs to create.

As you develop, test and deploy SSIS packages, you need to specify different parameter values for things like database connection strings, file and folder paths, etc. without having to edit the individual SSIS packages to make these changes. Ray Barley looks at how you can accomplish this goal by taking advantage of the configuration capabilities that SSIS provides, in particular the SQL Server package configuration.

Hi Team, I am trying to refresh the Azure Synapse Dedicated pool from production...
hi everyone I am not sure how to write the query that will produce...
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; See possible answers
