Updating using linq
operations in LINQ to SQL by adding, changing, and removing objects in your object model. Orders; // Removing it from the table also removes it from the Customer’s list.
By default, LINQ to SQL translates your actions to SQL and submits the changes to the database.
To update data, you need to fetch it out, update the record, and submit the changes: Adventure Works Data Context db = new Adventure Works Data Context(); db. Out; // Get hte first customer record Customer c = from cust in db.
This is modification can be explained by reference parameter being passed to a method and getting modified there. It is a bad practice and could lead to really confusing code.
The output might instead be a sequence of values that is computed by using the source elements as input arguments.The following example shows how to create a new application that retrieves and updates information in a SQL Server database.The examples in this topic use the Northwind sample database.LINQ to SQL offers maximum flexibility in manipulating and persisting changes that you made to your objects. As soon as entity objects are available (either by retrieving them through a query or by constructing them anew), you can change them as typical objects in your application. Contact Name = "New Contact"; // Create and add a new Order to the Orders collection.
However, you can map stored procedures to methods and call those.
