If you’ve ever had to format dates and times in SQL, you’ve probably come across one of the most jarring realities of working across platforms: every major RDBMS does it differently and sometimes confusingly. What’s a TO_CHAR() in Oracle becomes FORMAT() or CONVERT() in SQL Server, and its sort of the same in PostgreSQL… but […]
With the ever-increasing pace of the digital era, companies are continuously looking for opportunities to enhance efficiency, cut costs, and optimize operations. The most viable way to accomplish these is through Custom Automation Software Development.
This is a list of the builds for SQL Server 2022. There are other build lists available here. A list of all the builds that I can find and install on my Build VM. If you find a build not listed here, please let the webmaster know (webmaster at sqlservercentral.com). All builds are listed in reverse […]
Get a quick glimpse of using AI in SQL Server by implementing a machine learning system.
This article explores how to securely clone the master user permissions in Amazon RDS for SQL Server using a custom stored procedure, usp_rds_clone_login. It outlines a step-by-step process to generate, review, and apply a script that replicates server- and database-level access from the master user to a new login without directly exposing elevated credentials. The guide emphasizes the principle of least privilege, supports named account management, and enables transparent, auditable permission handling for DBAs and applications. Designed for secure and scalable environments, this solution enhances operational security while maintaining administrative flexibility in Amazon RDS.
There’s a moment I experience all too often in tech meetings, presentations, or vendor demos where someone starts talking, and instead of clarity, I get hit with a tidal wave of jargon: “synergizing AI-driven orchestration pipelines for real-time actionable insights using cloud-native microservices and agentic AI to serve as a digital twin.” And somewhere in […]
Overview In this article we will go through the various in built aggregate functions available in PostgreSQL. Aggregate functions perform a calculation on a set of rows and return a single value. COUNT Function The COUNT function is a simple and very useful function in counting the number of records, which are expected to be […]
Zero-Trust Architecture (ZTA) emerges as a strong security paradigm for cloud-based AI systems, fundamentally operating on the principle of “never trust, always verify.” Unlike conventional security models, ZTA assumes potential compromise exists within the network and requires continuous verification of every access request regardless of origin.
Sometimes, while working on something as foundational as SQL Server Central, (which is a temporary responsibility for Grant, John and I while Steve is on sabbatical) I catch myself falling into an old, familiar loop double-checking my choices, second-guessing even the most minor decisions, as is the norm for anyone who’s a database administrator (or […]

For the Question of the day, I am going to go deep, but try to be more clear, as I feel like I didn't give enough info last time, leading folks to guess the wrong answer... :) For today's question: You’re troubleshooting a performance issue on a critical stored procedure. You notice that a previously efficient query now performs a full table scan instead of an index seek. Upon investigating, you find that an NVARCHAR parameter is being compared to a VARCHAR column in the WHERE clause. What is the most likely cause of the query plan regression?
