DataSource Controls :: Returning Null Value From Procedure?
Jun 17, 2010
[Code]....
iam using asp.net2.0 with c# with sql server 2000 when iam executing the procedure in local system it is working fine.but when iam executing in client system procedure returns null value, i have checked all connection string , and session value all are working
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 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 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
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.)
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 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 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.
My insert is adding a record to the database in the call to the stored procedure in SQL Server, but a -1 is returned - Shouldn't it return 0 if the insert/update was successful?
I am trying to create a stored procedure where I can insert null values in columns that have a foreign key constraint and allow nulls. The columns I am trying to insert nulls into are commentid and imageid. I have created an Insert statement in a stored procedure and I get the foreign key constraint error. Can you tell me how to allow inserting data in the other columns without having to insert anything in the commendid and the imageid?
Here is my exec of the stored procedure that is not working:
This problem is driving me nuts. I have labels inside a gridview. When i reference them, i keep getting a null error. This is definatly that it cant find the labels inside the template. below is my code that i am using.
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'm trying to retreive values entered by users in the textboxes in the footer of the gridview and insert these values into another sql table.My code is as follows :-
protected void GridView2_RowCommand(object sender, GridViewCommandEventArgs e) { if(e.CommandName.Equals("addnew")) { TextBox t1 = (TextBox)GridView2.FooterRow.FindControl("tfrm"); string frm = t1.Text; TextBox t2 = (TextBox)GridView2.FooterRow.FindControl("tsub"); string sub = t2.Text; string cmd = "insert into suggestions values('" + frm + "','" + sub + "','c','c')"; con.Open(); SqlCommand com = new SqlCommand(cmd,con); int a = com.ExecuteNonQuery(); GridView2.DataBind(); con.Close(); } }
But the strings 'frm' and 'sub' returns null values.
I want to execute a method on VB.Net to return a date which is in the stored procedure. I tried using ExecuteScalar but it doesnt work it retruns error
'Implicit conversion from data type datetime to int is not allowed. Use the CONVERT function to run this query'
below is the code
Public Function GetHolidaydate(ByVal struserID as String) As DateTime Dim objArgs1 As New clsSQLStoredProcedureParams objArgs1.Add("@userID", Me.Tag) objArgs1.Add("@Date", 0, 0, ParameterDirection.Output) Return (CDate(ExecuteScalar(clsLibrary.MyStoredProcedure.GetHolidayDate, objArgs1))) End Function

Dim hwr As HttpWorkerRequest = CType(context.GetType.GetProperty("WorkerRequest", Reflection.BindingFlags.Instance Or Reflection.BindingFlags.NonPublic).GetValue(context, Nothing), HttpWorkerRequest)
3) AFter That checking where request has body or not and the calling GetPreloadedEntityBody() which is returning null alway for IIS7.0 ,while in IIS6.0 same code is working fine.
if hwr.HasEntityBody Then Dim preloadedBufferData As Byte() = hwr.GetPreloadedEntityBody() end if
what more do i have to do so that i can get return value form GetPreloadedEntityBody() function.
