Entity Data Model and database view returning the same columns as there are in a table


When adding a stored procedure into the Entity Data Model I can select whether the procedure returns a scalar, a (new) complex type or one of the entity types I already defined. 

How do I do something similar for a view?

I mean assuming I have a view like this

CREATE VIEW FilteredFoos as SELECT Foo.* FROM Foo join ... WHERE ...

(that is a view that implements some involved filtering, but returns all columns from one table) how do I add it to the project so that I can use the entity set, but get the Foo objects, not some new FilteredFoo objects.

var foos = myDB.FilteredFoos.Include("Bar").ToList();

foreach (Foo foo in foos) { ...

Thanks, Jenda

Error in Uploading Files to Access 2010 Web Database Table with Data Macro


Hi All,


I've recently published an Access 2010 Web Database to the SharePoint 2010 farm in my organization and I'm having the strangest problem.

I have a table which includes an Attachment field. When trying to upload a file through the web I get the following error: "There was an error uploading your attachment to the server".

Now, this table has a "Before Change" Data Macro, which basically executes a simple LookUp of several parameters from another table and writes them back to the "master" table. When deleting this Data Macro, upload on the Web works fine.

The thing is that when working from the local Access file (connected to the SharePoint) and trying to change a field in the table, the following error is received: "The Microsoft Access database engine encountered an error whil

Checkboxes from data table


I have a data table that contains some values for Certifications.  This table can be updated in a different part of my application.  On the web page I am currently working on, I would like to have check boxes appear for every value in the data table.  I have been struggling with this trying to use a For Each loop and I cannot get it to work for anything.  Any suggestions? 

I am using the following Razor syntax to obtain my data (I know this works because I can display it in a WebGrid):


var db = Database.Open("MyConn");
