ADO.NET :: Select Stored Procedure Called By LINQ In Entity Framework?
Jan 6, 2011
I have a stored procedure that receives 2 parameters and returns 3 columns.
Here is how I added the SP:
1. Added SP to entity model (.edmx) via update model from DB.
2. Did a Function Import -- selected my SP, clicked "Get Column Information" and then created a new complex type (myStoredProcedureName_Result) which I assigned.
I have a stored procedure in SQl and i am calling through Entity framework through import functions. Stored procedure is returns columns from 2 different tables.. now what should be return type at Entity framwork end ?
I am new to entity framework , it is really very good , but I want to know what is the difference between using entity framework with stored procedure or without stored procedure , which one the faster and what is the benefits for using stored procedures with entity framework.
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.
I have a aspx page that only has a button and a button click event.
My code behind looks like this

This code works fine if I have no insert stored procedure mapped to Table UBOtest in the EntityDataModel.However, when I map the stored procedure to the EntityDataModel and add UBOtestinsert I get an error that reads "An error occured while updating the entries. See the inner exception for details.">/P> Then the innerException message is "Invalid object name 'UBOtest'
Here is the stored procedure [Code]....
I will enclose to screen snapshots...the first my mapping screen. the second is when I right click stored procedures in the Model Browser and right click stored procedure UBOtestinsert. -- it does not show any columns....should it?
How can i make and call function using this stored procedure?
alter PROCEDURE [dbo].[select_value] -- Add the parameters for the stored procedure here @Keyword varchar(1000) output, @ResultHead varchar(1000) output, @Year int
i joined together more than one entity: Customer, Personel etc. i used inner join structures. if i look adonet entity framework ,5 entities are generated. i need to run this SP in C# side:

How can i get all joined data from sql with using randevu.GetRandevular(customerID
I have a stored procedure that generates a float value. I've added the stored procedure to my edmx file and created a function import, but the function isn't showing up in the object browser or via intellisense.
I'm using Visual Studio 2010 and I've verified that the stored procedure works in SSMS. Here is the current stored proc I'm using:
How do I use a stored procedure to change one or more (but not all) fields of a entity in EF4? I have a stored procedure "ChangePassword" taking a username and and a password as parameters and a User entity containing properties for Username and Password as well as other properties. I want to be able to use this stored procedure from a function to update the password from a function in one of my repositories. How to do this?
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...
am new to entity frame work and having a hell of time building a stored procedure that insertsa value into a table using a Scalar stored procedure and returning the new ID which is a Unique Identifier. I am trying
<EntitySet Name="EntityFramework" EntityType="SEOAnalysisModel.Store.EntityFramework"> <DefiningQuery> SELECT Keyword, ResultHead ,Year from SeoAnalysis where Year = 2005
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.

how can I create stored procedure and write my select statement in it, I know how to create dataset then put type stored procedure and assign it to the sp ... what I want is writing my sp... how can I make it ?
check the following code, this is what I want to write put I don't know where or how !
I have an application that uses an aps:GridView. The GridView is populated using a DataSource that calls a Stored Procedure. The DataSource passes parameters to the Stored Procedure based on some text fields. The page has been running slower than wanted, so I was doing some checking.
I ran SQL Profiler while loading the page, and saw the Stored Procedure was being called twice. I stepped through the code and found out that in the Page Load Complete event was where this was happening. In this event, I set the value of a parameter for the Stored Procedure, then did a DataBind on the GridView to pick up the data. As I was stepping through the code, I watched the SQL Profiler. When I got to the step of setting the parameter, the Stored Procedure had not yet been called. When I stepped through that and got to the DataBind command (before running that step), the SQL Profiler showed that the Stored Procedure had been called. Then I did the DataBind and the StoredProcedure was called again.
My question is, how do I get the parameters set, and get the GridView data bound, and only call the StoredProcedure once? If I comment out the DataBind step, the StoredProcedure never does get called (which seems really strange to me...).
I am trying to get the @@Identity from a table by using a stored procedure called by my asp.net website. I am using a datareader to do this but get an error as it tells me it cannot convert the returned value to getint. Here is my code. What should I be using instead of getint?
Dim myReader = cmd.ExecuteReader() While (myReader.Read()) intID = myReader.GetInt32(0) End While myReader.Close()
