What is the difference between linq to sql and linq to objects?


Asked by Nalani Vasquez on Dec 07, 2021 SQL



LINQ to SQL is translated to SQL calls and executed on the specified database while LINQ to Objects is executed in the local machine memory . The similarities shared between all aspects of LINQ are the syntax. They all use the same SQL like syntax and share the same groups of standard query operators.
Accordingly,
LINQ is based on SQL. LINQ is a Microsoft .NET framework component that adds native data querying capabilities to .NET languages. It was originally released as a major part of .net framework 3.5 in 2007. In contrast, SQL is a domain specific language used in programming and designed for managing data held in a Relational Database Management System.
Similarly, LINQ to Objects is a component of the .NET framework that allows using LINQ query supporting IEnumerable<T> for accessing in-memory data collections. In other words, it provides a method to use collections. Usually, a programmer writes for each loop to retrieve data from a collection. Instead, he can use LINQ to Objects easily.
In respect to this,
LINQ stands for language integrated query. It allows you to use "SQL style" query language directly within C# to extract information from data sources. That data source could be a SQL server database - this is Linq to SQL. That data source could be an data context of entity framework objects - Linq to entities.
Keeping this in consideration,
Entity framework is a great ORM shipped by Microsoft which allow you to query and modify RDBMS like SQL Server, Oracle, DB2 and MySQL etc. by using LINQ syntax. Today, EF is widely used by each and every .NET application to query to database. The difference between LINQ to SQL and EF is given below.
