LINQ to SQL tracks your changes and is ready to transmit them back to the database when you call Submit Changes.
LINQ to SQL offers maximum flexibility in manipulating and persisting changes that you made to your objects.
I've been doing the 'two DB calls' method since starting to use LINQ to SQL but I've always had a nagging feeling I was missing an obviously easier answer. Save Changes(); // this is for EF LINQ to Objects _db. It's tedious but at least I know now I've been doing it the 'proper' way, even though it doesn't seem like doesnt matter what fields have been edited by the user, as long as you pass the model to the Action Result in your controller in HTTPPOST method and call the Save Changes(), the entire records gets updated in the DB. For more information, see Customizing Insert, Update, and Delete Operations.Developers using Visual Studio can use the Object Relational Designer to develop stored procedures for the same purpose.operations in LINQ to SQL by adding, changing, and removing objects in your object model.By default, LINQ to SQL translates your actions to SQL and submits the changes to the database.First, we will have to retrieve the ‘user’ object we want to delete, and then add this deletion operation in the queue by ‘Delete On Submit’ method.
