VIEWs are an undervalued and underused feature in SQL. They basically consist of a query that has been given a name, and a parameter list, so can be used like an inline macro. Technically, you’re supposed to think of it as a virtual table.

Most SQL bulk insert and SQL Server openrowset tutorials skip file access issues that can stop imports cold. Both the bulk insert statement and openrowset function rely on the SQL Server service account to read a source file. The SQL Server service account must have read permission on the file or its folder. It is also convenient to have read & execute as well as list folder content permissions.

You have a Power BI project that generates real-time reports for an inventory management system that uses SQL Server. You are aware that Power BI performance is heavily influenced by how your data is structured in SQL Server but don’t have a clear understanding of how to optimize your SQL data structure for Power BI. In this article, we look at different ways to structure the data and tables to help improve Power BI query performance.

Running Postgres in Docker is great for a quick test but what if you want it to behave like a proper, production-style setup with SSL encryption, certificate-based authentication, persistent volumes, and custom configurations? In this article, we’ll find out how

Searching for a string in database tables has been discussed over the years. There are several approaches to the problem (see References at the end of the article). See how to use SQL to find a string in different types of SQL Server objects and data.

SQL Server 2025 introduces a new sys.dm_os_memory_health_history view to make it easier for meatbags like you and robots like Copilot to know if the SQL Server has been under memory pressure recently.

Data is usually the most important asset in organizations, but only SQL developers can frequently access that data. Technical teams often write queries for non-technical users. This restricts agility, slows decision-making, and creates a bottleneck in data accessibility. One possible remedy is natural language processing (NLP), which enables users to ask questions in simple English and receive answers without knowing any code. Still, the majority of NLP-to-SQL solutions are cloud-based, which raises issues with cost and privacy.

The JOIN statement is one of the most common operations SQL developers perform. Yet in a world ruled by Inner and Left Joins, the poor Full Outer Join is like Cinderella before the ball – allowed out on only the rarest of occasions. In an (unscientific) survey I once performed of SQL developers at one Fortune 100 firm, half of the developers had never used a Full Outer Join in production code, and the rest had used it in a tiny handful of occasions.

A countdown timer can be a powerful visual tool in many Business Intelligence reporting scenarios. This could be for marketing campaigns, contract expiries, and business deals with clients. Real-time countdown visuals are not natively supported in Power BI. Although, there is the Count Down Timer custom visual, which is not dynamic in its configuration.

While doing some testing of an application, I wanted to reset my environment after doing some testing with this code:
USE DNRTest BACKUP DATABASE DNRTest TO DISK = 'dnrtest.bak' GO /* Bunch of stuff tested here */RESTORE DATABASE DNRTest FROM DISK = 'dnrtest.bak' WITH REPLACEWhat happens if this runs, assuming the "bunch of stuff" isn't anything affecting the instance. See possible answers
