What if you could go back in time and see exactly what your database looked like yesterday, last week, or even last year? Sounds like something out of a sci-fi movie, right?
Well, Temporal Tables in SQL Server let you do exactly that!
Ever wished you could store semi-structured data in your database without dealing with complex table relationships? Good news! SQL Server has native JSON support, and EF Core makes working with JSON columns easier than ever.
Whether you’re handling dynamic configurations, logging data, or flexible user preferences, JSON columns let you mix structured and unstructured data in SQL Server—without creating dozens of extra tables.
Not everything in your database needs a primary key. Sometimes, you just want to query views, stored procedures, or raw SQL results without forcing a unique identifier on them. That’s where Keyless Entity Types in EF Core come in!
If you’ve ever struggled with querying database views, reports, or read-only datasets, this feature is exactly what you need. Let’s dive into what Keyless Entity Types are, when to use them, and how to make them work in EF Core.
Grouping data in Entity Framework Core (EF Core) used to feel a little… clunky. Sometimes, LINQ’s GroupBy() worked beautifully in-memory but got lost in translation when executing SQL queries. You’d write a simple GroupBy(), and EF Core would pull all the data into memory before doing the grouping—not good!
But things are getting smarter and more efficient in recent versions of EF Core! With LINQ GroupBy enhancements, EF Core now translates more grouping operations into optimized SQL queries, saving memory and improving performance.
We’ve all been there—you’re halfway through a multi-step transaction, and boom! 💥 Something fails. You don’t want to roll back everything, just the part that went wrong.
That’s where Transactional Savepoints come in!
Savepoints let you partially roll back transactions, keeping the good stuff while undoing just the problematic parts. If you’ve ever wished for a “Ctrl + Z” in database operations, this is it.
Not all database tables are created equal! Sometimes, you don’t need direct access to raw data—you need a refined, read-only version that makes querying easier. That’s where database views come in!
Have you ever needed to store coordinates, track locations, or perform distance calculations in your database? Whether you’re building a ride-sharing app, a location-based service, or an interactive map, working with spatial data is essential.
Luckily, EF Core supports spatial data types, allowing you to store, query, and manipulate geographic data seamlessly. No more treating latitude and longitude as simple numbers—let’s bring real GIS (Geographic Information System) power to your EF Core apps!
like at first glance—cryptic, overwhelming, and maybe a little intimidating. But don’t worry! Once you embark on the journey to analyze and understand query plans, you’ll be unlocking hidden performance treasures like a true database pirate, and you’ll be amazed at how much you can grow and learn in the process.
Ever wonder who changed what and when in your database? Or maybe you’ve had that “uh-oh” moment where data was updated, but no one knows how?
Good news: EF Core has a built-in way to track changes—without modifying every query manually! SaveChanges Interception lets you hook into EF Core’s SaveChanges() pipeline and log inserts, updates, and deletes automatically.
Remember when dealing with many-to-many relationships in Entity Framework felt like trying to assemble IKEA furniture without instructions? You needed an extra join entity and sometimes a sprinkle of luck to get it all working. EF Core has come to the rescue, making many-to-many relationships as easy as pie (or a fully assembled bookshelf) and giving you improved configurations that put you in the driver’s seat.
