Moving from PostgreSQL to SQL Server? Learn the key differences between timestamp, timestamptz, datetime2, and datetimeoffset, including precision, time zones, offsets, and storage.
I went looking for Azure SQL Database in a recent coding agent benchmark, honestly unsure whether Microsoft SQL would show up. Armature ran a study where real coding agent CLIs (Claude Code, Codex, Cursor) were dropped into six synthetic-but-realistic repositories and asked to pick a database, then actually build with it. 356 runs were completed ac...
Good software design principles apply inside the database too. See how decomposition, encapsulation, statelessness, and clear contracts can make complex T-SQL easier to read, test, reuse, and maintain.
Schema changes are inevitable, but downtime doesn’t have to be. Learn a phased approach to safely evolve a production SQL schema while applications remain online.
When you need to move an entire database or move the objects in a database, bacpac and dacpac files often come up because of all of the tooling options to interact with them. Bacpac and dacpac files share some core similarities as well as some major differences in how they're used in SqlPackage and other SQL tools, but their flexibility can create ...
Microsoft.Data.SqlClient includes configurable retry logic for SqlConnection and SqlCommand, giving .NET applications built-in resilience for transient SQL Server failures without requiring Polly.
Bob Ward and I recently released a series of videos, read more in the original blog post or go directly to the series on YouTube. The Azure SQL Database Foundations series are four videos that take you from your first Hyperscale database to AI features running against your own operational data. We also included how to assess and migrate (with AI...
If you’ve been building local prototypes, internal tools, web backends, or lightweight services on SQL Server Express, you know the routine: it’s free, familiar, and gets the job done – until you hit hardware limits or spend weekends manual backup scripts and handling OS patches. Learn how to upgrade from SQL Server Express to Azure SQL Database fr...
Writing and maintaining SQL is easier when you can eliminate repetitive steps and keep your scripts cleanly formatted. With the MSSQL extension for VS Code v1.45, we're introducing the Public Preview of the SQL Formatter alongside the General Availability of Azure SQL Database Provisioning and Shortcuts Configuration. You can now apply consistent T...
Hybrid search is usually described as combining keyword search with vector search. Microsoft SQL does that, for sure, but we do quite a bit more right out of the box. SQL dynamically evaluates queries and switches between kNN and ANN vector search based on cost and selectivity. These two types of hybrid search, work together, ensuring your semantic...
