Trying To Insert Data / Getting Error "no Value Given For Required Parameters"?
Jan 14, 2011
I am pretty sure this is a basic syntax error, I am new at this and basically figuring things out by trial and error... I am trying to insert data from textboxes into an Access database, where the primary key fields in tableCourse are prefix and course_number. It keeps giving me the "no value given for one or more required parameters" error. Here is my codebehind:
Protected Sub Wizard1_FinishButtonClick(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.WizardNavigationEventArgs) Handles Wizard1.FinishButtonClick
'Collect Data
Dim myDept = txtDept.Text
Dim myFirst = txtFirstName.Text
Dim myLast = txtLastName.Text
Dim myPrefix = txtCoursePrefix.Text
Dim myNum = txtCourseNum.Text
[Code]...
And it inserts the data, I checked the database and it's all there, but it still gives me an error:
"The changes you requested to the table were not successful because they would create duplicate values in the index, primary key, or relationship. Change the data in the field or fields that contain duplicate data, remove the index, or redefine the index to permit duplicate entries and try again."
I get throw a error message when i execute the following code
// Setup Connection string ConStr = @"Provider=Microsoft.ACE.OLEDB.12.0; Data source =" + (Request.PhysicalApplicationPath + "App_Data\Information.accdb"); ; // Create a new Sql Connection OleDbConnection cn = new OleDbConnection(ConStr); //Create the DataSet ds = new DataSet("ds"); //Create a new Oledb Data Adapter OleDbDataAdapter da = new OleDbDataAdapter("SELECT * FROM Buyers WHERE UserID = " + LblWelcome.Text, cn); // Fill the Data Adapter da.Fill(ds); //Set the Datasource for the DetailsView equal to the DataSet DtVBuyer.DataSource = ds; //Bind your Data DtVBuyer.DataBind();
The error is No value given for one or more required parameters
Im getting error: No value given for one or more required parameters. in following code. I checked the code n found that if i remove cmd.Parameters.AddWithValue("PERIOD", period); from code and [period] = ? from command text, everything works fine. I am not getting what is wrong with period.
I have used Visual Studio 2008 ASP.NET AccessDataSource Wizard to generate the update command. The gridview edit button works. But when I click on Update Link in Gridview, I get this message:
System.Data.OleDb.OleDbException: No value given for one or more required parameters.
The update option is using a stored procedure. There are no parameters fro the SP but the error message is saying that parameters are expected. If executed as SQL string then it works OK. I need to use a SP as other updates are required. Code: THIS WORKS
USE [TMSWEBALL] GO /****** Object: StoredProcedure [dbo].[usp_TESTSP] Script Date: 10/06/2010 14:03:38 ******/ SET ANSI_NULLS ON GO SET QUOTED_IDENTIFIER ON GO ALTER PROCEDURE [dbo].[usp_TESTSP] As BEGIN SET NOCOUNT ON added to prevent extra result sets from interfering with SELECT statements. SET NOCOUNT ON; */ INSERT INTO dbo.tbl_DEBUG (ManifestId, ManifestTripId, LocationId, Manifestdate, RouteId, VehicleType, ManifestType) VALUES (1,2,3,'01/01/2010',4,5,6) END >
i am trying to update a excel file using the oledb connections. But i am getting the following error: "No value given for one or more required parameters."

I am simply attempting to use a details view to insert and edit fields in the database. Some fields in the database have value some are NULL. All fields except the id accept NULL values.This should be a straight forward process, but for some reason it isn't.
I would love to find out why this is causing errors.I have checked to make sure the field names are the same, and of course they are since this is generated by the control.I have tested the connection to the database and it is fine.I have attempted to hard code the values into the string, but that too gives me errors and would not be consistent with what I want this control to do.
Getting the message that ObjectDataSource ... count not find a non-generic method ... that has parameters ... The parameter list is fine until I get to the very end and it list the two data fields that are in my DetailsView. Using the ASP Tutorial #17 (Examining the Events Associated with Inserting, Updating, and Deleting) and the Exploring the Data Modification - specifically the one showing the INSERT of the Product Name and UnitPrice. ASPX page is pretty simple and attempting something similar, two fields to insert a new record - update the other fields later.
Full Error Message follows along with ASPX and the AsignaturasBLL.cs. Interesting thing is that when I swap the two fields in the DetailView, then the last two fields in the error message are swapped. In the error message I bolded these two fields.
Are they any special Insert Paramters I shoud/need to use on a formView. I currently have the below datasource but when submitted it only inserts <NULLS> intot he required table.
[Code]....
The fields that aren't being inserted are already pre-populated via the following used FormViews:
I am using Visual studio 2010 express and I have a details view databinded to an sql database table. When I use the Insert option on the view it causes an error due to it trying to insert a null into the primary key field. If the Insert function does not create a new primary key entry how is it created?
I have already create special folder to copy default picture for new user and put it inside that folder.
I have used copy method (system.io.file) to do that and works fine but I have to give full path for two required parameters of copy method for example:
I have datagrid that is connected via an object data source (VS 2008 / VB). I want to use paging. I have created the required attributes in the ASPX code shown below and with a corresponding Select method. Yet I get the error shown below even throug there is a select method that should work. I have set forth below the error, the ASPX code and the first part of the Select Method.

I want to delete a row in a way that it shows, but displays an error.
I did the data access tutorials on this site.They used validation controls for the insert and the edit template fields. Each of these used their own validation summary control. The markup for them is below. Can I use the same validation summary control for both the insert and the edit validation controls? It seems redundant if i can set the Validation Group property to the same value then I would only need to use one validation summary.I don't know if this is allowed, or a good idea though.
How can I use required field validators in the insert item template in a listview control? The empty fields in the insert item template are preventing the user from deleting or updating ay other row.
We have created a new cname for our subdomain website. The new website is working properly with cname. We do have .net application inside the webiste which is not working with cname. For eg,1. http://servername/_folder1/app/mypage.aspx (Accessing .net application (App) website without cname)2. http://NewDomian.xxxx/app/mypage.aspx (Accessing .net application (App) website with cname)The first case is working perfectly, but when I access the second url, I got the following error.Description: An error occurred during the processing of a configuration file required to service this request.

I would like to create a common stored procedure for all insert operations performed in my Database. So i created a stored procedure as below.
[Code]....
But now my problem is how to pass parameters for this stored procedure. I have got the column names of the table passed. But i would like to pass the parameters for each insert operation of each table to identify which value is passed for which parameter.
how to pass parameters for this stored procedure.
(Parameter can be Column name prefixed @ i.e. @Column name)
It is possible to get the column names in another Stored Procedure . But how to prefix @ for each column and pass this as parameter to the Common Insert Stored Procedure?
I have been in the process of updating my code with security methods, and I've been learning this from [URL] (or "Security Guidelines: ASP.NET 2.0"). In the middle of the page under "When Constructing SQL Queries, Use Type Safe SQL Parameters" it says "Use type safe parameters when constructing SQL queries to avoid possible SQL injection attacks that can occur with unfiltered input". Now, what they suggested was to use code like:
"DataSet userDataset = new DataSet(); SqlDataAdapter myCommand = new SqlDataAdapter(LoginStoredProcedure", connection); myCommand.SelectCommand.CommandType = CommandType.StoredProcedure; myCommand.SelectCommand.Parameters.Add("@au_id", SqlDbType.VarChar, 11);........"
So, that would be how I would modify my current code base to use type safe parameters in sql updating/inserting.
Getting to my actual question, as it was said "Use type safe parameters when constructing SQL queries to avoid possible SQL injection attacks that can occur with unfiltered input". First off, this suggests that this should apply to unfiltered input. Also, in their example they only did this for an ID.
So, what I'd like to know, when it comes to "unfiltered input", does this mean as long as the input is unfiltered I must use type safe parameters, or even filtered input shall have this (just to be sure), like, input that has been ran through a regularexpression check? Shall I do this for all values I insert/update into the database, or just IDs and important things?
The way I see it right now is that it would be a good precaution to just do type safe checks on everything (literally) that updates/inserts into the database just to be extra safe. But, I really am unsure if this is really the best idea, because if I did, would this possibly cause overprocessing of information? Can this cause too much strain on server resources? If my fears serve true, what would be a good suggestion of how I could implement this properly without having to worry about what I said?
here when users enter new mobile number it should insert data into database and show 'You have been registered' and if they enter Mobile number that was in table it shouldn't insert data into database and show=='You can just register 1 Time'
problem is when I enter new mobile number it inserted data into database but it showed this message'You can just register 1 Time' but here it should show 'You have been registered' I mean in both condition it show this message 'You can just register 1 Time'
it never show this message='You have been registered'
