How do you update a table with a foreign key to another table in ADO.Net Entity Model?

Question

I have 2 tables, Table1 has a primary key \'CustomizationId\', and Table2 has a FK Customizationid which matches this. Table2 has no primary key.

I am trying to add

As far as the EF is concerned the table without a PK is a View.

This means you have two options:

1. Tell a little white lie, and convince the EF that the 'view' is a table
2. Add modification functions (Insert/Update/Delete) so you can edit them.

Generally modification functions are stored procedures, but you can actually add T-SQL directly to the SSDL if you don't have access to the database...

I.e. something like this in the element of the EDMX for each action (insert, update and delete):

       
                INSERT dbo.TCode(ID, Name) VALUES (@ID, @Name)
       
       
       

Once you have the modification functions in your SSDL you need to map them so that the EF uses them as required.

In your situation I recommend (1).

Hope this helps.
