To demonstrate update record into the database, we have updated the list view of listing post to add a Edit link just beside the Auto ID value as demonstrated below.Clicking Edit link send the user to Edit action method of the controller with autoid querystring value. action method (below) of the Web API controller is called (remaining code for the button click has been already explained while explaining how to create a new rocord into database by consuming ASP. Sql Client; namespace Insert_update_delete It's difficult to tell what is being asked here. That's 18 extra column of data that were retrieved for nothing. If someone in the future changes the schema of that table and inserts of column between columns 0 and 1, then your results may not be what is expected.Below is a class model created for the Northwind sample database and which I'll be using in this blog post: When we designed our data model using the LINQ to SQL data designer above we defined five data model classes: Product, Category, Customer, Order and Order Detail.The properties of each class map to the columns of a corresponding table in the database.
