No Value Given For One Or More Required Parameters?
Feb 17, 2010
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."
Database MSSQLSERVER 2008.Visual Web Developer 2008 Express
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.
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.
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:
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 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."
When I want to get the output values its okay but I also want returning a table as a result data.But Datareader has no rows.is it possible if I want a returning query result and multiple output values togather ?I wrote a test above.I can get output values as sqlparameters. But Datareader attached to a Gridview is empty.can you detect whats wrong here and it doesnt return a query result.So stored procedure is not standart or ı am doing something wrong.this doesnt raise any exception.but not returning any data.
Since ASP.NET MVC3 RC2 I encounter a bug when posting values to a controller method of which one of the parameter is a nullable int. Steps to reproduce:
I've created a test method
[code]....
In MVC3 RC1 this was working without any problems with the nullable int
Update: I don't seem to have the problem with a newly created MVC3 website. What could I have in my project that influence model binding to nullable int's? And why would there be a difference between RC1 and RC2?
I am using jquery ajax method on my aspx page,which will invoke the webmethod in the code behind.Currently the webmethod takes a couple of parameters like firstname,lastname,address etc which I am passing from jquery ajax method using
now my requirement has been changed such that,the number and type of parameters that are going to be passed is not fixed for ex.parameter combination can be something like fname,city or fname,city or city,lname or fname,lname,city or something else.So the webmethod should be such that it should accept any number parameters.I thought of using arrays to do so, as described here.
But I do not understand how can I identify which and how many parameters have been passedto the webmethod to insert/update the data to the DB.
here is my code for selectiong some records from db table
string strSql = "select * from mtblNBD where SentTo=@SentTo and InternalStatus Is NULL order by DeadLine desc"; SqlCommand com = new SqlCommand(strSql, con); com.Parameters.Add("@SentTo", SqlDbType.NVarChar, 50).Value = (string)Session["uname"];
here I am using parameters for SenTo field but not for NULL so it is ok... or should I use parameters for this field where value is NULL , if yes then how can I use parameter for this
I have two examples to show you what I want to achieve here. But to point what's different about my question, Is that I'm having a parametrized URLs and I want to implement URL rewriting to my application. But I don't want to convert the parameter in the URL to be placed between slashes..."page.aspx?number=one" to "pages/one/" << NOT!
First example:
http://localhost:1820/Pages/Default.aspx?page=2&start=5 To http://localhost:1820/Pages/page2
Second example:
http://localhost:1820/Items/Details.aspx?item=3 To http://localhost:1820/Items/ItemName
But I'll still need all the parameters in the original URLs
I have a stored procedure that works fine for classic asp, but how can I get my output parameters data back from in /MVC 2 / linq/ entities framework model . I have inported the function also, but when i try to code it i dont get results ...i know this is a matter of lack of / knowledge or exmple because i have been scouring the web for it and cannnot find into that accually works.
here is the stored proc.
[Code]....
Here was the one of the few tries I did:
[Code]....
but it executes fine does not give me an error, but also does not return the info i need to the viewmodel
I keep seeing stuff about "ref" on the net but "ref" shows " arbument # should not be passed with the ref keyword.
So i am not sure if there is a problem with the model, or with my understanding this, Now for your info I can do the same step with returning a dataset from a stored procedure fine, but I dont want a data set I just want excatly the data in the output parameters from the stored procedure.

I need to have a GridView listing all invoices of an account. Each account can have a PDF generated for that account, which isn't done instantly - so I need a gridview column to update the user of the progress of this conversion - i.e. 'In Progress'. Then, when the conversion is done the cell's text should change to a hyperlink to the PDF file. I know it's a very vague question in regards to monitoring the state of the PDF, but I'd just like to know if AJAX would be a solution and what controls I would use.

Do I need to implement all the required methods on the MembershipProvider and RoleProvider if writing a custom one to use the AuthorizedAttribute in ASP.NET MVC?
There are a few features that I don't want to implement like CreateUser or 'DeleteRole` because they violate the system I will be authorizing/authenticating against.
What are the licences required for an asp.net (MVC) web application using sql server running a windows server ? Is Windows Web Server 2008 R2 enough for running SQL Server 2008 Web ? Is it possible (legal ?!) to install SQL Server on a "Web" operating system ? What are the limitations ? An official link would be nice
