sql server 2008 - How to create a relationship between table and view in the Entity Framework -


I have a unit framework model that was generated by the Visual Studio 2008 Wizard on a SQL Server 2008 database.

There is a view of the model that has entered into many-to-many relationships with another table through a logically joined table (applied to the database by an insert / update trigger) . Both tables are part of the visual model, but because you can not have a foreign key obstacle on a view, there is no connection between the view and the included table.

Is it possible to create a relationship between the Entity Table and the View in the Unit Framework Model for this link?

Thanks for any help.

Yes, you can do this, but the GUI designer will not be able to estimate it for you.

The first thing you need to do is the designer can not assess the primary key, so you will need that information.

Now you can right-click on the empty space in the designer and then choose to add an association.

In EF1, you will need to remove the FK field by pressing the client schema and selecting it in the designer. That's because, in EF1, you can not map the same field in both an association and a scalar property. If you use the FK Associations in EF4, you can keep the FK field, or you can use an independent association that behaves like EF1.

sql - dynamically varied number of conditions in the 'where' statement using LINQ -

I am using my first project LINQ (in mvc), so maybe there's something very simple that I remember. However, a day of searching and experimenting does not work, so it works. I am trying to write a LINQ query (Linux to SQL) in which in many cases where the statement is different from an OR or an AND. We do not know how many conditions are going in the query till runtime. This search is for filter control, where the user can choose multiple criteria for filtering. Select from table where table.col = 1 or table.col = 2 or table.col = 7 .... 'Other number of conditions Before I just create the SQL query as a string, while looping over all the situations. However, it seems that there should be a good way to do this in LINQ. I tried to use Expression trees, but they had a second thought for this moment on my head, where the lambda function was to be executed inside the statement such as: values ​​for matchingRows = matchingRows for each value Where (function (row) row.c...

asp.net mvc - Dynamically Generated Ajax.BeginForm -

I have a problem with ASP.NET MVC Ajax forms. I generate many Ajax form in a table such as: & Lt; Input type = "submit" name = "activity" value = "add activity" / & gt; & Lt;%}% & gt; & Lt; / TD & gt; & Lt; / TR & gt; & Lt;%}% & gt; So far so good. When I post one of those forms, it gives a partial view in a div, and in this new partial view a new Ajax Beginnform (which is not in Genesis form) This second Ajax Beginnorf is exactly like the ones I got on the table, but when I post it, I do not get the "Ajax Post", but a normal post that sends me to a new page, I do not know whether the two Ajax forms What is the reason for the difference between, why is it the "dynamically generated" Ajax form behaves like a normal HTML form? By the way, I know that I can do it in different ways using javascript, but I would like to understand whether it can only be done using MVC helplars and Ajax lib...
