SQL to Lambda Expression Conversion: A Guide and Explanation

This SQL query: 'SELECT A.StationNo, COUNT(A.StationNo) FROM [Mesdatabase_6631].[dbo].[Work_Process] A LEFT JOIN Base_Station B ON A.StationNo=B.StationNo GROUP BY A.StationNo,B.SortIndex ORDER BY B.SortIndex' cannot be directly translated into a Lambda expression. Lambda expressions are a syntax for writing code, while SQL is a language for interacting with databases. Lambda expressions are typically used within LINQ queries, not for direct database interaction.

If you desire to use Lambda expressions for querying, consider utilizing an Object-Relational Mapper (ORM) like LINQ to SQL or Entity Framework. These frameworks provide a bridge between your code and the database, allowing you to express queries using Lambda expressions, which are then translated into SQL by the ORM.
