What are the differences between LINQ in ASP.NET Core and SQL?

What are the differences between LINQ in ASP.NET Core and SQL?

LINQ (Language Integrated Query) in ASP.NET Core allows you to query data in a more readable and concise way compared to traditional SQL. It integrates seamlessly with C# and provides compile-time checking, while SQL is a separate language that requires string manipulation and is executed at runtime.

Can you give me an example of how to use LINQ in ASP.NET Core?

Sure! Here's a simple example:

var products = from p in dbContext.Products
               where p.Price > 100
               select p;

This LINQ query retrieves all products with a price greater than 100 from the database.

What are the performance implications of using LINQ versus SQL?

Generally, LINQ can be less performant than raw SQL for complex queries because it adds an abstraction layer. However, for most applications, the difference is negligible, and LINQ's readability and maintainability often outweigh performance concerns.

Is it possible to mix LINQ and SQL in an ASP.NET Core application?

Yes, you can mix LINQ and raw SQL in an ASP.NET Core application. You can use LINQ for most queries and raw SQL for specific cases where performance is critical or when you need complex SQL features.
