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.

3. My LINQ is the following:

MVC :: Linq To SQL Using Stored Procedure

Feb 15, 2010

I am trying to re-write an existing website using MVC with Linq to SQL. A page we have is used to insert new contracts and uses usp_contract_insert to insert a new contract into t_contract as well as t_project. On my dbml file i have dragged t_contract on and then I try to drag usp_contract_insert on top of that and I get the error :- Microsoft Visual Studio

One or more selected database objects return a schema that does not match the schema of the target data class. Nothing has been added to the designer. The stored procedure returns the id of the last project which was inserted. I don't quite follow this and unsure how to go about hooking my Controller up using Linq to SQL to call this stored procedure

Running Stored Procedure Using Linq Into SQL Members Table?

Sep 8, 2010

Using MVC in c#, I am making a call to a stored procedure using Linq into my SQL Members table. I have no internal caching on the application, already checked to make sure it is turned off.

Test case:I have my username set to test1. From the website I change my username to test2. The website still shows test1. I go to Management Studio and run my stored procedure called MemberByEmail, it shows test2 correctly.I start simple, refresh my page to see if it's browser cache, still test1. I go to debugging and walk through the code and find that it goes correctly all the way to here to call the database:

/// <summary>Method that is mapped to the dbo.MemberByEmail database procedure.</summary>
/// <returns></returns>

Again I ran the stored procedure through Management Studio, and it came up with test2 as the username. I waited for 15 minutes, refreshing the web page every 5 or so, and it never cleared and served the correct test2 from the db. The last strange piece, I ran IISReset and refreshed the page, test2 was returned.

UPDATE: I created a console application to take out the web piece of it. The problem is the same when accessing directly from a console app also, no change.

DataSource Controls :: Returning String Value Using Stored Procedure And Linq

Feb 7, 2010

I am having problems returning a string value through a stored procedure/linq to a label. Everything works fine if I return an integer value but I cant get a string value to bind to a label. I get the error message

Microsoft.VisualBasic.CompilerServices.Conversions.ParseDouble(String Value,
NumberFormatInfo NumberFormat) +201
Microsoft.VisualBasic.CompilerServices.Conversions.ToInteger(String Value) +66
[InvalidCastException: String "System.Data.Linq.SqlClient.SqlPr" to 'Integer' is invalid]

This is the stored procedure
Select ProductName
From Products

This is the vb page
Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
Dim db As New DataClassesDataContext
Dim product As Integer = db.test.ToString
Label1.Text = product
End Sub

This is the aspx page

C# - Can Execute A Stored Procedure Using Linq In A Background/alternate Thread

Feb 4, 2011

In my app I am using the open xml sdk to generate a word document and write the file to the response.output stream for the user to download.

At the time that the letter is generated I also need to call a SP via linq data context to update a row in my db.

I think that I need to execute this SP in a seperate thread so that I can simultaneouly write the file to the output. my method looks like this...

protected void btnPrint_Click(object sender, EventArge e)
//call sp to update
//create letter and send to client

Is this feasible or should I avoid seperate threads?

DataSource Controls :: Using LINQ Passing The Name Of The Stored Procedure Dynamically?

Feb 23, 2010

I have an application where depending on what the user selects run a different stored procedure.

I am using LINQ and am passing the stored procedure name into a sub that will run the stored procedure and return values that I am loading into a DDL.

For example I want to pass the procedure name "GetProducts_Hats" to the sub and not hardcode it.

Protected Sub LoadParamDropDowns(
ByVal SqlObjToExec
String )

I am passing the storedprocedure name in parameter SqlObjToExec

so instead of

values = mydb.GetProducts_Hats

I want to code it to be a variable

values = mydb.SqlObjToExec

But the above code does not work.
