DataSource Controls :: Accessing The Result Set Of A Stored Procedure - How To Fix This Error
Jul 27, 2010
I'm programming a webpage in ASP.NET which displays a list of students not listed as participants in something, and upon clicking a student name shows you a brief summary of their details, so the user can ensure they're selecting the right person. Each student is identified by a unique ID.
My code currently correctly obtains their ID, adds it as a parameter to my stored procedure and executes the procedure;
[Code]....
However, when I try to access the results, with say dv.Table.Rows[0], I get the following error:
[Code]....
Upon debugging, there don't seem to be any results returned... when running just the stored procedure in SQL Server with the same data, it does return a single row, as expected.

How do I access this result so I can bind it to my fields?
(I am working in ASP.NET 3.5 in Visual Studio 2008, with SQL Server 2008.)
I am bulding a dvd catalog and have a table called DVD which holds all my details about each dvd except Genre, Director and Actor as I want more than 1 Genre, Director, Actor per DVD so put these in seperate tables to avoid repeating the data and used a joining tabe to join the tables so the tables I have are
DVD, Genre, Director, Actor, DVDGenre, DVDDirector and DVDActor
I have now written a stored procedure to pull the info about 1 DVD out of all the tables to display on the webpage I have now got the info I want out of the tables but as the data is now in 1 table I have repeating data is there a way to stop the data repeating the stored procedure i have written is
Just after some advice I have a stored procedure that returns several tables. I then need to loop through the tables and create dynamic gridviews using the data. At the moment this stored proc is called using

I have used an xsd file to populate everthing else, but due to this returning multiple tables i wasn't sure how this works should it just be in its own xsd? as all the oather i just get a datatable where as with this i need a dataset... how this makes sense...
I am using a sql stored procedure which returns multiple result sets. By default Sql Datasource is binding the first result set to gridview. I want the second result set to be binded. I browsed all the properties in Sql datasource but could not find one to set this.
I'm still trying to deploy this site, but with every problem I solve, another arises. Anyways - I've set up the database at my hosting to allow remote connections, and it is running Sql Server 2005. On my development machine, I am working with Sql Server 2008.
I've installed the asp.net schema on my hosted database, and have created several users from the ASP.NET web administration interface, as well as tested that the login works. Running the application locally with the remote connection string nets the same results. However - I'm able to run my scripts and generate my tables and stored procedures without errors - but when the site is run I get the following error on all of my .aspx pages that try to access a stored procedure:
Server Error in '/' Application. Incorrect syntax near 'LoadProfileData'. Description: An unhandled exception occurred during the execution of the current web request. review the stack trace for more information about the error and where it originated in the code.
Exception Details: System.Data.SqlClient.SqlException: Incorrect syntax near 'LoadProfileData'.
Source Error:
Line 62: adapter.SelectCommand.Parameters.Add("@ProfessionalName", SqlDbType.VarChar).Value = professionalName; Line 63: DataSet profile = new DataSet(); Line 64: adapter.Fill(profile, "Profile"); Line 65: return profile; Line 66: }
Is this a possible Sql 2005 vs 2008 issue? I'm hoping someone else has seen this issue in a similar scenario and can point me in the right direction. The server is running asp.net 2.0, 3.0 and 3.5 and IIS 7.0.
Stored Procedure:
Drop procedure CreateDefaultProfile GO Create procedure CreateDefaultProfile(@UserName varchar(256)) as declare @ProfessionalID uniqueidentifier
I have a button which the admin will click on every new acad year to update the student's study level.
I have written a SP to do this process, however, it was working fine. But I faced problem when I did testing.
This is my student update study level stored procedure:
UPDATE Student SET acadLevel = (CASE WHEN acadLevel < '3' THEN convert(char,acadLevel + 1) ELSE convert(char,'G') end ) WHERE acadLevel between '1' and '4';
Error: Conversion failed when converting the varchar value 'G' to data type int.
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.
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 have a stored procedure that creates a dynamic query. Sometimes the query is not built because there are no elements in the dynamic query. When the aspx page loads the SqlDataSource throws an error that the query is malformed. How can I catch this error, and handle it with a default message, before it returns the error to the aspx page?
sing VS 2008 at a workstation, I have successfully developed a local, file-system ASP.NET 3.5 website. The wbesite included a membership page with Windows authentication and a web parts page. The SQL Server 2005 ASPNETDB database has been created at an IIS web servr. Using the ASP.Net development server of the workstation, both the membership Membership/WebParts pages at the local website worked very well.
Then, I copied the website to a virtual directory at the IIS web server and creates a remote website for the workstation. Under theASP.NET development server of the workstation, both membership and webparts pages of the remote website at the IIS web server also worked fine.
However, when running these web pages from the IIS web server machine, something wrong happened with the web parts page. (The membership page still worked very well.) For the ASPNETDB database at the IIS web server machine, there is an EXECUTE permission error on an ASPNET stored procedure.
What are the differences between the ASP.NET development server and IIS web sever, which caused the EXECUTE permission error on the ASP.NET S.P.? How to find and fix the errors?
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
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?
i am using paging technique from this tutorial [URL] and it is working fine, i used asp.net 2.0 with sql server 2005 then i upgraded to visual studio 2008, and converted the asp.net 2.0 application to 3.0 and now using sql server 2008 all the existingpages and .xsd files are working, fine, i can see data in .xsd files when i preview it but i cannot add new stored procedures it gives me an error "An unexpected error has occured" Error message:unexpected error i dont know what it is, already configured dataset (.xsd) works fine, it is just that iam unable to add stored procedures to new datasets my connection string
<add name="jobcon" connectionString="Server=HOME-46CTBUROCXSQLEXPRESS; Database=jobdhundo; User ID=; Password=;Timeout=200; Trusted_Connection=True" providerName="System.Data.SqlClient"/>
it is fine with the entire application there is no coding involved
I have a MVC project that has a Linq to SQL dbml class. It is a table called Clients that houses client information. I can easily get the information to display in a View using the code I followed in Nerd Dinner but I have added a stored procedure to the dbml and it's result set is of IQueryable, not IQueryable. I need to convert IQueryable to IQueryable so I can display it in the same View. The reason for the sproc is so I can pass a search string tothe sproc and return the same information as a full list but filtered on the search. I know I can use Linq to filter the whole list but I don't want the whole list so I am using the sproc.
Here is the code in my ClientRepository with a comment where I need to convert. What code goes in the commented spot.
public IQueryable<Client> SelectClientsBySearch(String search) { IQueryable<SelectClientsBySearchResult> spClientList = (from p in db.SelectClientsBySearch(search) select p).AsQueryable(); //what is the code to convert IQueryable<SelectClientsBySearchResult> to IQueryable<Client> return clientList; }
I have an aggregate stored procedure (named sp2) that returns a count of records meeting a certain criteria ASrecCount. I am using a DAL per the ASP.NET tutorial and have created a Table Adapter (named sp2TableAdapter) with GetData and Fill methods. I have a button on an ASP.NET page that launches an event handler. In the button's event handler, I have this line: sp2TableAdapter sp2 = new sp2TableAdapter(); What works so far:
This code will bind the value of sp2 to a data control:
When running this page and clicking the button, the numeric value of recCount returned from sp2 is bound to the DropDownList control and 1 row is poplated with the recCount value (in my case 1451).
Problem: In the event handler, I do not want to bind the value of recCount to a control, but want to to use it in some logic as an integer. What is the C# code that will do this? (In place of the DropDownList control lines above)
