Linq to sql view not updating Sex chats one on one trail
This logic is based on the schema of the table (the column definitions and primary key information).If you do not want this behavior, you can configure an entity class to use stored procedures to perform Inserts, Updates, and Deletes instead of using the default LINQ to SQL runtime behavior. Company Name; foreach (var customer in company Name Query) ' Northwnd inherits from System. Dim nw As New Northwnd("c:\northwnd.mdf") ' or, if you are not using SQL Server Express ' Dim nw As New Northwnd("Database=Northwind; Server=dschwart7; Integrated Security=SSPI") Dim company Name Query = _ From cust In nw. Write Line(customer) Next // Northwnd inherits from System.
) is achieved by just writing a LINQ query in your own programming language, and then executing that query to retrieve the results.
Complex mapping, such as mapping an entity class to multiple tables, is not supported.
However, you can map an entity class to a view that joins multiple related tables.
In the following example, all customers who are from London are retrieved. Then, after confirming that the customer row was retrieved, Delete On Submit is called to remove that object from the collection.
// In LINQ to SQL, the change is not sent to the database until // Submit Changes is called. Submit Changes(); ' Northwnd inherits from System. After you have modified the object, call Submit Changes on the Data Context to update the database.
