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
ALTER PROCEDURE test
AS
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
<form id="form1" runat="server">
<asp:Label ID="Label1" runat="server" Text=""></asp:Label>
</form>
I can return single integer values when using stored procedures with Linq but I cant get single string values returned.

I call this stored procedure with a dataset. It always returns a 0 but should return a 1 or 2. Does anybody know why it isn't returning a 1 or 2.

I am developing a page in ASP.Net where I have the user enter a letter into a textbox. They then click a submit button and I all of the userids that start with that letter are to be displayed. So I need the SP to go through the database and match first letters with what was entered. Here is what I have as my code for the SP:
CREATE PROCEDURE dbo.exp2 @testchar Char(1)
declare @flag as char(2)
set @flag = @testchar + '%'
select userid
from ex_database
where userid like @flag
I have simple stored procedure to check if there is any email address in the database entered by user or not. My SP should return 1 when user enters a correct email. However, it is returning 0 or -1.
View 3 RepliesI am having problem in returning a status message (success or failure) from my sql server sp here is the code:

"Status" is an output parameter which is supposedly getting the message from sp and we are not able to get its value since
"dbCommand1.Parameters["@status"].Value" returns NULL everytime!
SP is available on request.
Is it possible to have a stored procedure return multiple ref cursors to a .Net application? I tried this, but it didn't work.
<code>

odr.NextResult()

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.
Im trying use a storedprocedure where depending on the status of the room if ='Vacant' And checkIn =date and the result will be put in a gridview, but i kept returning an error that says, "Conversion failed when convertng datetime from character string". Heres the code.

I have problem with a stored procedure and function that return the same shape, but as they are different methods LINQ won' t let me cast between the two. Please see code for the two SPROCs below (This is actually simplified to represent the problem, so please don't spend lots of time explaining alternative ways of writing the function/sproc.)

I have a Procedure which should return only 1 Record on selecting record according to Priority.
BEGIN
DECLARE @Accounts nvarchar(MAX)
SELECT @Accounts = ISNULL([map_user_modules].[Accounts], '') FROM [map_user_modules]
WHERE [map_user_modules].[id_user] = 231 AND [map_user_modules].[id_module] = 5

Select @@ROWCOUNT as Priority3
END
IF @@ROWCOUNT = 1

Return
END
BEGIN
Select @@ROWCOUNT as Priority4
END
IF @@ROWCOUNT = 1
BEGIN
Return
END
In the above statement Suppose we take a scenario where Select @@ROWCOUNT as Priority3 is executed, I get two tables returned, One is the Table returned by Select @@ROWCOUNT as Priority3 and the other is the Table returned by Select @@ROWCOUNT as Priority2 which has no Records. How can I eliminate the Empty table that returns no records.
I am using

In my stored Procedure, I am doing a lot of calculation with joins and it took 19 sec to execute at my sql Server 2008. My application had been working perfectly for 5 days but now as database increases, I found a problem that my connection is breaking at that point. At Sql Server, it execute fine but when I add a breakpoint and watch the stored procedure is returning null.
I am trying to return single string result through a stored procedure and Linq. This works fine when I test the stored procedure but it is not returning the value to the page. The value returned is always 0 which is the return value. This is the stored procedure:
ALTER PROCEDURE Login
@CustomerName nvarchar(50),
@Password nvarchar(50) output
As
Select @Password=Password
From Customers
Where Customers.CustomerName=@CustomerName
This is the vb
ALTER PROCEDURE Login
@CustomerName nvarchar(50),
@Password nvarchar(50) output
As
Select @Password=Password
From Customers
Where Customers.CustomerName=@CustomerName is the code created by the designer
This is the designer function
<FunctionAttribute(Name:="dbo.Login")> _
Public Function Login(<Parameter(Name:="CustomerName", DbType:="NVarChar(50)")> ByVal customerName
As String, <Parameter(Name:="Password", DbType:="NVarChar(50)")> ByRef password As String) As IntegerDim result
As IExecuteResult = Me.ExecuteMethodCall(Me, CType(MethodInfo.GetCurrentMethod,MethodInfo), customerName, password)
password = CType(result.GetParameterValue(1),String)
End Function
My Stored procedure takes one parameter @IDs and it has values in it like '1,2,3'. I want to get rid of these single quotes. How can I do it? Like I want just 1,2,3 and NOT '1,2,3'. How do I modify this parameter value inside my SP?

Being new to using the declarative syntax of SqlDataSource I am trying to figure out a way to set the value of a parameter to a stored procedure. I have a Client_ID that is passed via the Request Object and I need to set the Client_ID before the stored procedure of the SqlDataSource is executed.
Does the stored procedure parameter have to be predefined in the ASPX markup or can it be added dynamically in the code-behind? Would anyone have an example that demonstrates the SqlDataSource markup with a stored procedure and parameter as well as setting that parameter value in code-behind?

View 2 RepliesI have an application with 40 or so separate databases that share a number of identical table schemas. Each is for a separate agency that performs functions identical (nearly) to the others. I have a number of reports that involve complex queries that each agency is required to produce. There is a "top-level" agency that would like to run the same reports but have the data consolidated for ALL agencies. I have tried having the query generated simply re-produced for each sub-agency by using a "UNION" ..
SELECT .... FROM [Agency].[dbo].[Table] ... UNION SELECT ... FROM [Next Agency].[dbo].[Table]....
This works for a few agencies selected/included but when they try to select all agencies or more than a few, it fails because the query is too large. I have tested a stored procedure:
CREATE PROC Test @DB AS
SELECT ... FROM [@DB].[dbo].[Table]...
Thinking I can build a smaller query by having up to 40 items of "EXEC Test (db) UNION EXEC Test (next db)" That also fails.... won't permit the database specifier as a parameter (plus, I don't know if I can do a UNION on the EXEC results).
i made stored procedure like that
select AssetCode ,Description
,EquipmentID from [FATMS].[fnMaintenanceHeaderRead](@ContextUser,@ContextClient,@ContextLang,@ContextApp,@ContextOrg,'1',@fnXmlParamMaintenanceHeader)

where MH.Status
IN
( @Status)
when i put three values for parameter (@status) not work but one value work
how to put three values please to parameter @status when excecute that stored procedure
EXEC @return_value = [FATMS].[spMaintenanceReport]
@ContextUser = N'4806',
@ContextClient = 1,
@ContextLang = N'en-US',
@ContextApp = N'FATMS',
@ContextOrg = 23,
@ActionCode = N'1',
@MaintenanceHeaderId='',
@SearchText='',
@EntryType='0',
@Status=N' '
SELECT 'Return Value' = @return_value
I am trying to re-write an existing asp.net 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
