What is the difference between SQL and LINQ?

SQL is a standardized declarative query language executing on database engines. LINQ (Language Integrated Query) is a C# language feature that allows developers to write queries inside application code, compiled into SQL dynamically by ORMs like Entity Framework.

Are subqueries supported in the translation?

Currently, this converter supports standard SELECT, FROM, JOIN, and WHERE mappings. You can manually nest the generated queries for advanced subquery structures.

Converting SQL Projections to C# LINQ Expressions

When transitioning backend applications to .NET frameworks (such as ASP.NET Core with Entity Framework), developers frequently need to translate existing, optimized database queries into equivalent LINQ syntaxes.

This utility automates that translation. It maps your query target tables, formats outer and inner keys for JOIN equals conditions, converts SQL logical operators (AND/OR/=) into C# operators (&&/||/==), and formats anonymous projection outputs.

Developer Tip:LINQ query syntax matches SQL keywords, but is written backward (starting with from and ending with select) to provide Intellisense auto-completion inside IDEs.

Frequently Asked Questions

Is it secure to paste my queries?

Yes. The translation logic executes in-memory inside your web browser sandbox using local JS. No database details or values are shared.

Does it support Entity Framework Core?

Yes, the generated query syntax conforms to standard IQueryable C# structures, making it fully compatible with EF Core, LINQ to SQL, and Dapper LINQ extensions.
