I am using Entity Framework 5.
I have a stored procedure that was added to the model some time ago. Now i have add a new parameter. I tried using "Update Model From Database..." but it doesn't add the new paramerter to the c# generated code.
In the edit menu of the stored procedure from the model browser tab all i could find was to update the columns that the stored procedure returns.
Is there any way of refreshing the parameters that the stored procedure expects without removing the stored procedure from the model and then adding it again?
The solution is following:
1) In your .edmx, right-click and select Model Browser.
2)Find Function Imports, expand it and double-click your stored procedure.
3)Click the Update button.
4)Click ok and save your .edmx to reflect changes in your project.

I'm using the Entity Framework to create a complex types from some stored procedures. Now, I changed one of the stored procedure to display 2 more fields.
I'm trying to update the complex type that maps to this stored procedure, but it's not working! Also, I tried both approaches:
Delete all 3 parts in model, and add again
Update the Model from the database and then update function imports
but they did not work!
Also, in the first way, when I add the stored procedure to the model, the complex type isn't updated. Besides, in the second way, when I "Edit Function Imports" and "Get Column Information", I get a message
The selected stored procedure or function returns no columns
while it's returning about 30 columns through a select statement!
The last part of my stored procedure is like this:
select *
from MyTable
where Name like '%My Name%'
This problem happened with me when I update the EDMX from existing database, but I solve it through:
Check the output of stored procedure in your database.
Do this steps:
Delete the EDMX.
Delete the connection string in app.config , save app.config and close app.config.
Clean the project.
Add EDMX again.
Rebuild the project.
hope this fix the problem.
I have two newly created stored procedures in my database. I tried to import those two stored procedures by going to Model Browser -> Function Imports -> Update Model from Database -> Add (tab) -> Selecting the newly created stored procedures under Stored Procedures and Functions -> dbo and clicking Finish button.
Note: I have checked 'Import Selected Stored Procedures and functions into the entity model' option.
The above step helped in adding the required stored procedures into my model/edmx.
But the problem I am facing is, it is also updating the other tables where there are few changes to one of the table where few columns were deleted in some table. This table has nothing to do with the stored procedures that I am importing. But it is asking me to update that table as well even though I have selected only the stored procedures.
Can someone please help me out why is this checking other tables which are not related to my newly added stored procedures even though I have selected to import only those stored procedures? how can I avoid other changes which are not relevant to my stored procedures?
I deleted a stored procedure from the database, then trying to update the entity framework model, and I see Stored procedure / functions have been updated, but the function imports didn't.
Below is the image explaining the problem
Currently, I am doing this way:
1. Delete the stored procedure from database
2. Run the EF update wizard
3. Go to Function Imports folder
4. Delete the stored procedure
5. Go to Complex Types
6. Delete the complex type
How to fix this ?
I work with database first Entity Framework & LINQ in Visual Studio 2013.
When i write stored procedures and change them, i used to update Entity Data Model from database by choosing stored procedure updating option.
It is weird that the 'import selected stored procedures and functions into the entity model' option comes disabled so I cannot choose stored procedures and functions for updating model anymore..
Can you please help me to find the problem?
You only have to import stored procedure and functions into the model when they're new. So when there are no new ones the option is disabled.
This doesn't mean that, as you seem to suspect, EF doesn't update existing stored procedures and functions. It does.
I am trying to import a stored procedure using Entity Framework 4 in an Asp.Net MVC project using C#. But when I try to update the model into entity diagram (*.edmx), it will be updated into the Entity name.Store inside stored procedure folder.
Stored procedure:
CREATE PROCEDURE Sp_Feedback
AS
BEGIN
SELECT
f.User_Id, f.Over_All_Rating, f.Features_Liked,
f.Features_Need_Improvement,
f.Will_Recommend_Us, f.Customer_Service_Rating, f.Comments
FROM
Feedback f
END
In my stored procedure I have selected a few columns from the table (not all columns). So I need to add a new entity for model mapping to the table. Once entity is created and add scalar properties to the entity to specify exact name in the table which I need to retrieve through the stored procedure. At last I had to mapping the new entity property name to the exact table entity.
When you expand the expand the stored-procedure folder there is a imported stored procedure right click stored procedure select Add Function Import option and dialog open displays that "Function Import Name" and "Stored Procedure Name" is already detected from the stored procedure and there is another option which is "Returns a Collection Of"
It contains four option which are
None
Scalars
Complex
Entities
In the Returns a Collection option I had to select the entities option to select the newly created entities for the mapping the stored procedure retrieved columns, because I need to get the list of records from the table.
Once I finished build the project, I got an error which is there is "no key value" for the newly created entity while mapping to the table entity.
After that I added a scalar property name for key value to the newly entity to map to the table entity. Again I build the project I got another error which is both the entities have the same key value.
I need to import the Select query based stored procedure using Entity Framework 4.
