SqlDataSource Set To Stored Procedure, Tests OK In Wizard, Does Not Return Data When Executed

Apr 27, 2007

With a  Gridview Control, I set the SqlDataSource to be a stored procedure in a Sql Sever database. 

Using the wizzard to configure the datasource, the test returns lots of rows.  After completing the wizzard, the gridview control does not show the column names in the VS2005 designer.  For the gridview column headers the values are Databound Col0, Databound Col1, Databound Col2, ....)   This tells me I have a problem.

 I tried the same thing with a  simpler stored procedure. This test stored procedure does not call anything else, takes several input parameters, returns rows.  The column names show in the gridview control as expected.

 So I am trying to figure out why the first case of gridview with sqldatasource is not working and the second case works .  The stored procedure that is not working with my gridview calls multiple inner stored procedures and has #TEMP tables. My complex stored procedure ends with Select * from #Temp.

 Could the calling of other inner stored procedures and use of #temp tables contribute to the problem?  If yes then what is the strategy for using a gridview and loading it with the data that the complex stored procedure returns?

SSIS Hard Time Getting Back XML Return Data From Stored Procedure Call Executed By Execute SQL Task

Aug 9, 2006

I'm having a hard time to getting back an xml data back from a stored procedure executed by an Execute SQL task.

I'm passing in an XML data as a parameter and getting back resulting XML data as a parameter. The Execute SQL task is using ADO connection to do this job. The two parameters(in/out) are type of "string" and mapped as string.

When I execute the task, I get the following error message.

[Execute SQL Task] Error: Executing the query "dbo.PromissorPLEDataUpload" failed with the following error: "The incoming tabular data stream (TDS) remote procedure call (RPC) protocol stream is incorrect. Parameter 2 ("@LogXML"): Data type 0xE7 has an invalid data length or metadata length.". Possible failure reasons: Problems with the query, "ResultSet" property not set correctly, parameters not set correctly, or connection not established correctly.

I also tried mapping the parameter as XML type, but that didn't work either.

If anyone knows what's going on or how to fix this problem please let me know. All I want to do is save returning XML data in the parameter to a local package variable.

Thanks

Can't Get Sqldatasource To Return Results From A Stored Procedure

Aug 1, 2006

I thought I would impliment a new feature of my web page using stored procedures and the SqlDataSource object, for practice or whatever, since I don't normally use that stuff.
This is the stored procedure:set ANSI_NULLS ON
set QUOTED_IDENTIFIER ON
go

-- =============================================
-- Author:Lance Colton
-- Create date: 7/31/06
-- Description:Find the contest winner
-- =============================================

ALTER PROCEDURE [dbo].[AppcheckContest]
-- Add the parameters for the stored procedure here

@BeginDate datetime = '1/1/2006',
@EndDate datetime = '12/31/2006',
@SectionID int = 10,
@WinnerID int = 0 OUTPUT
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 top 1 @WinnerID = P.UserID
FROM cs_Posts P
WHERE P.PostDate BETWEEN @BeginDate AND @EndDate
AND P.SectionID = @SectionID
AND P.UserID <> 2100 -- I don't want to win my own contest...

AND SettingsID = 1000 -- This number could be different if i had more than one CS installed?

AND IsApproved = 1
ORDER BY NEWID() -- yes this is slow, but it works...

RETURN @WinnerID
END
 It's really simple - just needs to return the one randomly chosen integer userID. I've tested it in query designer or whatever it's called in Management Studio and it works fine there at least.
Thinking I was done the hard part, I created a new web form in visual studio, dropped a SqlDataSource on it, and used the 'configure data source' wizard from the smart tag to do all the work for me. I didn't have any trouble using the wizard to select my stored procedure, and i'm using the sa connection string to simplify my debugging. I tried using the FormParameter / FormField way of getting the output and setting the input parameters. I can't seem to get it working though. There's no errors or anything, just the output isn't coming through.
Here's the code from the aspx codebehind file:Partial Class Contest
Inherits System.Web.UI.Page

Protected Sub btnSelectWinner_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles btnSelectWinner.Click
Dim stuff As New System.Web.UI.DataSourceSelectArguments
SqlDataSource1.Select(stuff)
SqlDataSource1.DataBind()
lblWinnerID.Text = SqlDataSource1.SelectParameters("WinnerID").ToString
End Sub
End Class
 As you can see, I wasn't sure if you're supposed to call databind() or select() to actually get the stored procedure to execute, so I tried both. I was hoping the last line of code there would set the label to the value contained in the @WinnerID parameter, but instead it sets it to "WinnerID".
Here's the code from the .aspx file. Most of this was generated by the Wizard, but I messed around with it a bit. <%@ Page Language="VB" MasterPageFile="~/MasterPage.master" AutoEventWireup="false" CodeFile="Contest.aspx.vb" Inherits="Contest" title="Untitled Page" %>
<asp:Content ID="Content1" ContentPlaceHolderID="CPHMain" Runat="Server">
<asp:Button ID="btnSelectWinner" runat="server" Text="Find Winner" />
<asp:Calendar ID="Calendar_From" runat="server"></asp:Calendar>
<asp:Calendar ID="Calendar_To" runat="server"></asp:Calendar>
<asp:SqlDataSource ID="SqlDataSource1" runat="server" ConnectionString="<%$ ConnectionStrings:appcheck-csConnectionString-sa %>"
SelectCommand="AppcheckContest" SelectCommandType="StoredProcedure" CancelSelectOnNullParameter="False">
<SelectParameters>
<asp:FormParameter FormField="Calendar_From" Name="BeginDate" Type="DateTime" />
<asp:FormParameter FormField="Calendar_To" Name="EndDate" Type="DateTime" />
<asp:Parameter DefaultValue="10" Name="SectionID" Type="Int32" />
<asp:formParameter FormField="lblWinnerID" defaultvalue="666" Direction="InputOutput" Name="WinnerID" Type="Int32" />
</SelectParameters>
</asp:SqlDataSource>
 
<asp:Label ID="lblWinnerID" runat="server" Text="???"></asp:Label>

Rows Skipped Out In Stored Procedure While Return All Rows If Query Executed Seprate

Nov 8, 2007

Hi All,

I am using sql server 2005. I stuck out in a strange problem.
I am using view in my stored procedure, when I run the stored procedure some of the rows get skipped out means if select query have to return 10 rows then it is returning 5 rows or any other but not all, also the records displyaing is randomly coming, some time it is displaying reords 12345 next time 5678, other time 2468.

But if I run seperately the querys written in SP then it returns all the rows. Please give me solution why it is happening like this.

There are indexes in the tables.

Once I shrink the database and rebuild the indexes, from then this problem is happening. I have rebuild the indexes several time, also updated the statistics but nothing improving.


But nothing is improving

Differentiate Between Whether Stored Procedure A Is Executed Inside Query Analyzer Or Executed Inside System Application Itself.

May 26, 2008

Just wonder whether is there any indicator or system parameters that can indicate whether stored procedure A is executed inside query analyzer or executed inside application itself so that if execution is done inside query analyzer then i can block it from being executed/retrieve sensitive data from it?

What i'm want to do is to block someone executing stored procedure using query analyzer and retrieve its sensitive results.
Stored procedure A has been granted execution for public user but inside application, it will prompt access denied message if particular user has no rights to use system although knew public user name and password. Because there is second layer of user validation inside system application.

However inside query analyzer, there is no way control execution of stored procedure A it as user knew the public user name and password.

Looking forward for replies from expert here. Thanks in advance.

Note: Hope my explaination here clearly describe my current problems.

SqlDataSource With Stored Procedure With Parameters Returns No Data

Mar 21, 2007

I have a Gridview bound to a SQLDataSource that uses a Stored Procedure expecting 1 or 2 parameters. The parameters are bound to textbox controls. The SP looks up a person by name, the textboxes are Last Name, First Name. It will handle last name only (ie. pass @ln ='Jones' and @fn=null and you get all the people with last name=Jones. I tested the SP in Management Studio and it works as expected. When I enter a last name in the Last Name textbox and no First Name I get no results. If I enter a Last Name AND First Name I get results. I don't understand.
Here's the HTML View of the page. The only code is to bind the Gridview when the Search button is pressed.

Grouping Data Based On Return From Stored Procedure

Jun 15, 2007

I'm having some difficulty getting the appropriate results for my scenerio. I have two different datasets that I'm using. One is consisting of two joined tables and the other consisting of one sp. The sp's parameters rely on two things- one is the companyNum (inputed when the user runs the report) and two is the ContactNumType. The ContactTypeNum comes from the dataset of tables. I need to have a table consisting of this format:


ContactNumType1 (From the Tables)
File_Name1 (From the sp)
File_Name4 (From the sp)
File_Name3 (From the sp)



ContactNumType2 (From the Tables)
File_Name2 (From the sp)
File_Name7(From the sp)



ContactNumType3 (From the Tables)
File_Name5 (From the sp)



ContactNumType4 (From the Tables)
File_Name6 (From the sp)

File_Name10 (From the sp)
File_Name8(From the sp)
File_Name9 (From the sp)

So essentially what is going on is that every returned File_Name is grouped based upon the type of ContactNumType. My table returns the appropriate ContactNumTypes and the appropriate number of File_Names but returns only the first File_Name for each row. The File_Names should only grouped by the ContactTypeNums and each be unique. Is there any way to do that?


-------------------------------------------------------------------------------------------
Edited: I still am trying to work this out. I've tried a few run-arounds but none have worked. Adding custom code apparently is too risky at this point because of the security precautions that I've been instructed to take. Any help would be greatly appreciated as this project has been going on for days now....

Aug 30, 2007

Hi every experts
I have a exist Stored Procedure in SQL 2005 Server, the stored procedure contain few output parameter, I have no problem to get result from output parameter to display using label control by using SqlCommand in Visual Studio 2003. Now new in Visual Studio 2005, I can't use sqlcommand wizard anymore, therefore I try to use the new sqldatasource control. When I Configure Datasource in Sqldatasource wizard, I assign select field using exist stored procedure, the wizard control return all parameter in the list with auto assign the direction type(input/ouput....), after that, whatever I try, I click on Test Query Button at last part, I always get error message The Query did not return any data table.
My Question is How can I setup sqldatasource to access Stored Procedure which contain output parameter, and after that How can I assign the output parameter value to bind to the label control's Text field to show on web?
Thanks anyone, who can give me any advice.

Can I Use A SqlDataSource Control Exclusively To Pass Data To A Stored Procedure For Execution (insert/update Only)?

Feb 28, 2008

Hi,
I'm reasonably new to ASP.NET 2.0
I'm in my wizard_FinishButtonClick event, and from here, I want to take data from the form and some session variables and put it into my database via a stored procedure.  I also want the stored procedure to return an output value.  I do not need to perform a select or a delete.
For the life of me, I can't find a single example online or in my reference books that tells me how to accomplish this task using a SqlDataSource control.  I can find lots of examples on sqldatasources that have a select statements (I don't need one) and use insert and update sql statements instead of stored procedures (I use stored procedures).
I desperately need the syntax to:
a) create the SqlDataSource with the appropriate syntax for calling a stored procedure to update and/or insert (again, this design side of VS2005 won't let me configure this datasource without including a select statement...which I don't need).
b) syntax on how to create the parameters that will be sent to the stored procedure for this sqldatasource (including output parameters).
c) syntax on how to set the values for these parameters (again...coming from form controls and session variables)
d) syntax on how to execute, in the code-behind, the stored procedure via the sqldatasource.
If anybody has sample code or a link or two, I would be most appreciative.
Thank you in advance for any help!

Weird Situation - Stored Procedure Executed Twice

Aug 16, 2006

In SQL 2005 I have a stored procedure as below:@sub_no smallint OUTPUTBEGINBEGIN TRANSACTIONINSERT...INTOSET @user_no = (SELECT ...... FROM ....WHERE sub_no = @sub_no)INSERT...INTOEXE another_stored_procedure (it includes also BEGIN...COMMIT)EXE another_stored_procedure (it includes also BEGIN...COMMIT)SET @sub_no = .......COMMIT TRANSACTIONWhen Visual Studio (ASP.NET 2005) is open and I run the program,procedure is executed once without any problem. If I publish theproject and put files on another server (or even use the publishedfiles from my machine) I have an error because stored procedure isexecuted twice. @sub_no is used as input/output parameter.I followed/trace the steps in procedure and it seems that procedure isexecuted once with correct value of @sub_no. The second time procedureis executed, the value that it was assigned before COMMIT is used,which gives an error because the INSERT values have NULL values.In ASP.NET I call the store procedure once.What could be the reason ?Thanks a lot for any help.

It is slowing down the report considerably.

Any help would be appreciated!

Return Error Code (return Value) From A Stored Procedure Using A Sql Task

Feb 12, 2008


I have a package that I have been attempting to return a error code after the stored procedure executes, otherwise the package works great.

I call the stored procedure from a Execute SQL Task (execute Marketing_extract_history_load_test ?, ? OUTPUT)
The sql task rowset is set to NONE. It is a OLEB connection.

I have two parameters mapped:

tablename input varchar 0 (this variable is set earlier in a foreach loop) ADO.
returnvalue output long 1

I set the breakpoint and see the values change, but I have a OnFailure conditon set if it returns a failure. The failure is ignored and the package completes. No quite what I wanted.

The first part of the sp is below and I set the value @i and return.


CREATE procedure [dbo].[Marketing_extract_history_load_TEST]

@table_name varchar(200),

@i int output

as

Why is it not capturing and setting the error and execute my OnFailure code? I have tried setting one of my parameter mappings to returnvalue with no success.

Hello Everyone and thanks for your help in advance.  I am new to SQL Server 2005 and am trying to understand the Stored Procedure Wizard.  In SQL 2000, it seems that the wizard does a lot more fo the actual generation of the sproc.  Also, I haven't figured out how to change the wizard to create an update, insert, or delete sproc.  I'm hoping that I'm simply not understanding how to effectively use it, but it really seems like the wizard has taken a step back.  Can someone give me some insight or articles on how to effectively use this?  Any help would be greatly appreciated.

Gridview / SqlDataSource Error - Procedure Or Function &<stored Procedure Name&> Has Too Many Arguments Specified.

Jan 19, 2007

Can someone help me with this issue? I am trying to update a record using a sp. The db table has an identity column. I seem to have set up everything correctly for Gridview and SqlDataSource but have no clue where my additional, phanton arguments are being generated. If I specify a custom statement rather than the stored procedure  in the Data Source configuration wizard I have no problem. But if I use a stored procedure I keep getting the error "Procedure or function <sp name> has too many arguments specified." But thing is, I didn't specify too many parameters, I specified exactly the number of parameters there are. I read through some posts and saw that the gridview datakey fields are automatically passed as parameters, but when I eliminate the ID parameter from the sp, from the SqlDataSource parameters list, or from both (ID is the datakey field for the gridview) and pray that .net somehow knows which record to update -- I still get the error. I'd like a simple solution, please, as I'm really new to this. What is wrong with this picture? Thank you very much for any light you can shed on this.

How Can I Assign Data Returned From A Stored Procedure Into The Return Table Of A Table Valued Function

Apr 18, 2007

Here is the scenario,
I have 2 stored procedures, SP1 and SP2

SP1 has the following code:

declare @tmp as varchar(300)
set @tmp = 'SELECT * FROM
OPENROWSET ( ''SQLOLEDB'', ''SERVER=.;Trusted_Connection=yes'',
''SET FMTONLY OFF EXEC ' + db_name() + '..StoredProcedure'' )'

EXEC (@tmp)

SP2 has the following code:

SELECT *
FROM SP1 (which won't work because SP1 is a stored procedure. A view, a table valued function, or a temporary table must be used for this)

Views - can't use a view because they don't allow dynamic sql and the db_name() in the OPENROWSET function must be used.
Temp Tables - can't use these because it would cause a large hit on system performance due to the frequency SP2 and others like it will be used.
Functions - My last resort is to use a table valued function as shown:

FUNCTION MyFunction
( )
RETURNS @retTable
(
@Field1 int,
@Field2 varchar(50)
)
AS
BEGIN
-- the problem here is that I need to call SP1 and assign it's resulting data into the
-- @retTable variable

-- this statement is incorrect, but it's meaning is my goal
INSERT @retTableSELECT *FROM SP1

RETURN
END
