The edmx throws error 3027 no mapping specified me the above error, but when I go to the respective table and right click it - "Update Model from Database" there is no change, the error is still there. If I delete the table from the diagram by selecting it and pressing del, then in the Model Browser It disappears from the .Database but when clicking "Update model from Database" I cant see i in the "Add" list, all I can do is "Refresh" the table since I still see it in the refresh list (which should not happen because I deleted it! ) Please help me. I cannot afford to lose time on such trivial problems that VS throws at me.

Try deleting it manually from that xml file, then try to update again. Take backups tho :) –Thousand Oct 8 '12 at 11:05 Your sugegstion worked. Please rewrite as

Please keep in mind; I'm just beginning to learn and program the Entity Framework in .NET 4. In myEntity Model,I have added a custom property on a table which does not have https://social.msdn.microsoft.com/Forums/en-US/97a12446-b03e-4afe-96df-fdcb3d6054a6/error-11009-property-is-not-mapped?forum=adodotnetentityframework a corresponding database column. I intend to use this custom property to contain a concatinated string returned from a stored procedure. I have imported the stored procedure using the "Add Function Import" wizard and designated the return collection as a set of Entities derived frommy table. Everything looks good here, but the field on the table is throwing the error: Error 11009: Property 'FullName' is not mapped. I understand the property is not mapped because there is nothing in the database that represents a FullName. Can anyone help me to understand and resolve this problem?

Using this approach will not work for what you are trying to achieve, since any
sometime because until recently I've had little need for Entity Framework's EDMX mappings because we've generally been content with one-to-one table to entity mappings that LINQ to SQL https://leftlobed.wordpress.com/2011/03/02/getting-to-know-entity-framework-table-per-type-tpt-inheritance/ gives us. However, with the addition of a new module to our project that is close, but not quite the same as an existing module we've had to call on Entity Framework to generate http://forums.devart.com/viewtopic.php?t=14262 a proper inheritance hierarchy. What is Table Per Type (TPT) inheritance? It's the method of defining your SQL schema such that each sub-type will live in it's own table and share a primary key is not column with the parent table via a foreign key. That is, the primary key on the child table will be a one-to-one mapping to the parent table. Shows how Employee will be related to Contact using a common primary key linked via a foreign key Note: My naming standard is to name primary key's "Id" and any foreign key's with the table name (and potentially a verb) prefixed. E.g. is not mapped "ContactId". Generate your EDMX file Start your .edmx (ADO.NET Entity Data Model Designer) as described in many tutorials… Initially your tables will come through as associated entities. This is where we'll pick up… From the Toolbox, pickup the "Inheritance" and join from Employee to Contact. Delete the Association joining the two tables. Now you'll find that if you try to compile, you'll get: Error 3024: Problem in Mapping Fragment starting at line 79: Must specify mapping for all key properties (Contact.Id) of the EntitySet Contact. The problem here lies in the fact that our Employee's ContactId didn't auto-map to the Contact's Id field. Click on Employee, open the Mapping Details view and select the Column Mapping for ContactId Change the mapping using the drop down to "Id". The drop down now includes all properties from Contact as well. Map the Employee's ContactId column to the Contact's Id column Again, you'll find that if you try to compile, you'll get: Error 11009: Property ‘ContactId' is not mapped. Wait… Sure it is! Didn't we just map it to the Contact's Id column. Ummmm? Well, we won't need it anyway. So just delete it from the Employee entity's diagram. Delete the Employee's ContactId field Compile, and al
• Page 1 of 1 Mapping Ref Cursor out parameter to a Entity by rdwlaz » Wed 25 Feb 2009 23:08 Take this simple example: Let's say I have an entity called Customer with id (key), name, address. I have a Oracle stored procedure called get_all_customers. Code: Select allPROCEDURE get_all_customers(
p_cursor OUT t_cursor
)
IS
BEGIN
OPEN p_cursor FOR
SELECT
id, name, address
FROM
customer
ORDER BY
name;
END get_all_customers;
Using the "Create Function Import" I created a Function called GetAllCustomers and set the return type to the Customer entity. How can I map the columns from the cursor to the Customer entity. Is this possible in EF? I get Error 11009: Property '' is not mapped. Thanks in advance, rdwlaz Posts: 3Joined: Wed 25 Feb 2009 22:57 Top by AndreyR » Thu 26 Feb 2009 09:04 It is possible in EF. You should have an entity corresponding to the result set of stored procedure in your model. It should contain the same set of columns with the same names and types. If you don't have such table, create a view.

Andrey, I used the simple example just to paint a clear picture. However, what I doing is more complex. I'm trying to use existing sp's with business logic and map them to entities that I created in the conceptual model. I'll then expose the data using ADO.NET Data Service as AtomPub feeds. There are no physical tables to map the entites to and creating views is not an
