DataSource Controls :: Stored Procedure And Function Returning Same Shape
Jan 26, 2010
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.)
Table Valued Function
"getCategories()"
SELECT categoryName, categoryID FROM categories
SPROC "getUnusedCategories"
SELECT categoryName, categoryID FROM CategoryInstances cI
FROM dbo.SMAN_getCategories(@SiteMANID, @SectionID) c
LEFT JOIN @EntityResultsTable er

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.
ALTER PROCEDURE dbo.sp_InsertLinkVote
@LinkId int,
@LinkVoter nvarchar(50),
@LinkVotesDateTime datetime,
@LinkVotesGoodBad bit
AS
/* SET NOCOUNT ON */
　
If EXISTS
(SELECT
*
FROM
LinkVotes
WHERE
LinkId=@LinkId
and
LinkVoter = @LinkVoter )RETURN
1
ELSE
INSERT INTO
dbo.LinkVotes (LinkId,LinkVoter,LinkVotesDateTime,LinkVotesGoodBad)VALUES
(@LinkId,@LinkVoter,@LinkVotesDateTime,@LinkVotesGoodBad)RETURN
2
Here is were a call it in my code behind.
Dim VoteCheck
As
Integer
Dim InsertVote
As
New DataSetStoredProceduresTableAdapters.QueriesTableAdapter
VoteCheck = InsertVote.sp_InsertLinkVote(LinkId, User.Identity.Name, DateAndTime. Now,
True)
'0 is a good vote.
If VoteCheck = 0
Then
It seems to insert and not insert correctly, I just cannot get it to return the correct value.

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>

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
IF ((@Accounts = '') OR (@Accounts = 'All'))
SELECT @Accounts = null
BEGIN
Select @@ROWCOUNT as Priority2
END
IF @@ROWCOUNT = 1
BEGIN
Return
END
BEGIN
Select @@ROWCOUNT as Priority3
END
IF @@ROWCOUNT = 1
BEGIN
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
SqlHelper.ExecuteDataset(MyConnectionString, CommandType.StoredProcedure, "GetInformation", new SqlParameter("@ID", ID));
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 write a function that can be called to run a stored procedure. I pass the stored procedure name, followed by as many parameters as I need to run the procedure. I am able to do this by using the params keyword, so my function looks something like this;
[Code]....
How can I determine what the data type of the parameter is? Maybe I need to alter the string[] part, above?

Initially, I have tried to use stored procedure. But I changed my mind and preferred to call sql query in codebase with command text. However, it stills tries to find initially-called stored procedure (which is neither called or exists).I think that it is related caching. But I tried it with different browsers it did not work.What might be the reason?

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

I am using Visual Studio 2008 and SQL Server 2008 and have added a SQL datasource to my form.
When I configure the datasource, I choose my connection string which looks like this in my webconfig:
<connectionStrings>
<add
name="PSFSPRD_ConnectionString"
connectionString="Data
The database I am using has a schema called EQB and as such, my stored procedures are named as EQB.usp_SelectFunds, EQB.usp_SelectAccount, etc.
On the select tab of the Configure Data Source screen, I choose to use a stored procedure. The dropdown shows my stored procedures, however, the schema name does not show up in front of the stored procedures in the drop down. I see only usp_SelectFunds, usp_SelectAccount, etc.
I select one of the stored procedures and when I click TEST, I get the message that the stored procedure is not found. If I instead choose to use a SQL statement instead on the configuration screen and enter EXEC EQB.usp_SelectFunds and click TEST, it works fine.
Why are my stored procedures not showing up correctly in the stored procedure drop down and how can I fix this?

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.
