Recently, I have discussed about getting started linq to sql in c#
That articles also covered for creating select query for retrieving both single and multiple results.
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.
Now we should drag all the tables onto the left-hand side of the designer and save (as shown in the following figure).
That is, you can change their values, you can add them to your collections, and you can remove them from your collections.
LINQ to SQL tracks your changes and is ready to transmit them back to the database when you call Submit Changes.
Today, in this tutorial, I will try to give some more examples on other types of database operations, that writes/updates the database.
These will cover writing and executing ‘Update’/’Insert’/’Delete’ query in the proper way.
