ADO.NET :: Entity Framework - Entity Stored Procedure Mapping - Can't Update

Feb 10, 2011

I am mapping a stored procedure to an entity by right clicking on the entity (in the .edmx) and selecting "Stored Procedure Mapping." This brings you to a Mapping Details - "Name of Entity" Window that allows you to select the insert, update, and delete stored procedures associated with the Entity. It also maps the stored procedure parameter to the Entity "Property" (Column).

I'm gettin an error "error 2042: Parameter Mapping specified is not valid." The cause of the error is fairly obvious, in the Insert stored procedure that has been selected, a 'CHAR' parameter is being mapped to an Int32 Entity Property. I altered the stored procedure parameter to match the entity, I deleted the stored procedure, readded, and reslected it as the Insert function. I also cleaned, validated, updated model from database. No matter what I do, the parameter list in the mapping details doesn't reflect the change to the stored procedure. It's stuck on a char --> int32 mapping, even though it has been changed, like it's buried deep in meta data some where.

Entity Framework - Mapping Doesn't Map For Stored Procedure?

Jan 4, 2010

I have a stored procedure that search a view using full text.

I'm trying to map the results to an existing Entity (Sales), where I mapped the column MivType to SaleType (as it makes more sense, and I want to keep db names away from my web site). The stored procedure is mapped to a Function Import, and I've defined its ReturnType to Sales.

This work well as long as the entity has the same property names as fields names.

Here's my problem: when I change the property's name, I get the following error after running the imported function:

The data reader is incompatible with the specified 'Model.Sale'. A member of the type, 'SaleType', does not have a corresponding column in the data reader with the same name.

I can fix this if I change the property 'SaleType' to 'MivType' on the entity, but why should I do that? Isn't that what the mapping is for?

This means I have to use the exact same names on the stored procedure and the entity, so in effect, the mapping is ignored (I have names like YzrName, MivYaad, etc, and I don't like it).

Is there a simple way around this? I don't want to use the db names on my application, and prefer not to change the stored procedure...

ADO.NET :: Entity Framework - Stored Procedure Mapping, Excecuting SP With Float Parameters Separated By Commas

Sep 27, 2010

Im using Entity framework with POCO entity generator template + SQL Server. I have mapping to stored procedure that takes two floats as input.

After executing function from code with two doubles as parameters: 1.23 and 4.56, SQL Profiler shows:

exec storedProcedureName @arg1 = 1,23, @arg2= 4,56

This is causing an error because it looks like that stored procedure takes 4 arguments, but it should take only two and there should be dots insted of commas in these floats.

SQL Server :: Playing With Stored Procedure And Returning Value To Parm

Nov 9, 2010

I been trying to get a simple stored procedure called and get its returned value back to a parm. In this case I am trying the simplest one I can make to get it to work and the I can build form there. I have tried to do this about 100 times and I try try and say heck with it and do it with out using a stored procedure and move on but I would really like to figure this out. I created a stored procedure called ReqLineItemTotal. It looks like this

USE [OnBillPROD]
GO
/****** Object: StoredProcedure [dbo].[ReqLineItemTotal]
Script Date: 11/09/2010 14:08:39 ******/
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO
-- Author: Bill Blair
-- Create date: 11-9-2010
-- Description: ReqLineItemTotal
-- ALTER PROCEDURE [dbo].[ReqLineItemTotal]
-- Add the parameters for the stored procedure here
@SessionIDNo nvarchar(50) = 0

AS
BEGIN
-- SET NOCOUNT ON added to prevent extra result sets from
-- interfering with SELECT statements.
SET NOCOUNT ON;
-- Insert statements for procedure here select
(select SUM(dbo.TempReqDetail.Amount)
from dbo.TempReqDetail,dbo.tblReqAmountTypes
where dbo.tblReqAmountTypes.AmountType = dbo.TempReqDetail.AmountType and
dbo.tblReqAmountTypes.NumericOpperator = '+' and
dbo.TempReqDetail.SessionID = @SessionIDNo) -
(select SUM(dbo.TempReqDetail.Amount)
from dbo.TempReqDetail,dbo.tblReqAmountTypes
where dbo.tblReqAmountTypes.AmountType = dbo.TempReqDetail.AmountType and
dbo.tblReqAmountTypes.NumericOpperator = '-' and
dbo.TempReqDetail.SessionID = @SessionIDNo) AS LineItemTotal
END

From what I understand I should be getting my total back as LineItemTotal. So I want to call it pass it my parm of @SessionIDNo and have its returned value set to my @LineItemTotal parm. Trying to use these stored proc's always seems like way more work than they are worth but perhaps if I ever get the hang of it would make since to me.
