Query Error - No Value Given For One Or More Required Parameters
Feb 11, 2009
When I run this code :
Dim username As String = TextBox1.Text
Dim pass As String = TextBox2.Text
Dim con As New OleDb.OleDbConnection con.ConnectionString = "Provider=Microsoft.Jet.OLEDB.4.0;
Data Source=""C:Documents and SettingsSaeedMy DocumentsVisual Studio 2008Projects
[Code] .....
I get these error message:
"No value given for one or more required parameters." at the line:
dr = cmd.ExecuteReader(CommandBehavior.Default)
what is the error.
Trying to search a database from vb.net I have the following function
[Code]...
No value given for one or more required parameters. I found the code in a vb.net book someone lent me. It doesnt work at the moment and I wondered if I have everything correct the bit at the top in brackets (Phone LIKE?) is that saying check if there is a row in the 'Phone' column that is the same? Because I am also selecting Phone (the column) in that line? Later I say compare to Form3.Textbox1.Text so I am not sure whether they should both be 'Phone' inthe SQL line? Is it saying that If it finds something display whatever is in the details column to display in the text box?
<asp:AccessDataSource ID="productsubtype" Runat="server" DataFile="~/access_db/db_tables.mdb" SelectCommand="SELECT [type], [id],[subtype] FROM [prod_subtype]" UpdateCommand="UPDATE [prod_subtype] SET [subtype]=@subtype WHERE [id]=@id"
[code]....
When i press delete button in gridview i am getting error
I'm creating a login form with two text boxes and two buttons. I'm getting an error in the button1 click routine which is supposed to validate the userid and password. The error is in the Dim Reader line. It states; No value given for one or more required parameters.
Imports System.Data.OleDb Public Class Form1 Dim MaxRows As Integer Dim inc As Integer
I wanted to know how I can solve my error.I used the "Add New Datasources" wizard to create a conection to my acces database with visual basic.net 2010. I then added two more after I created the datasources and I dragged the table navigator from the dataset from the datasouces window and I ran the system and It was bringing the information and was working great. However I then decided to add a few more columns to my table, and that is where the problem began the next time I tried to run the system it gives the error "no value given for one or more parameters"If you think it you can achieve it

I'm not quite sure what im doing wrong here, im just trying to run this update query against my database. Basically its taking a value from the table Nameplate, and setting it to the corresponding value from the table [sheet1 (2)]
Everytime i run the query i get the error "No value given for one or more required parameters"[code]...
i've got a database with a table called Customers, and i've created a form so that i can edit the customer details and update the database. However when i click the update button, it doesn't work and keeps coming up with the error which i've put in the title.
Private Sub btnupdatecustomer_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnupdatecustomer.Click If MessageBox.Show("Are you sure you want to update your details?", "Save", MessageBoxButtons.YesNo) = Windows.Forms.DialogResult.Yes Then Dim intPosition As Integer
[code]....
The bold/underlined text is where the error is coming up.What am i doing wrong? I've got a feeling it is something really stupid as i modelled the code on an example project that a teacher gave me, so it's practically the same code except for the field names etc.
I'm getting this error, Update error: No value given for one or more required parameters, which seems to indicate a variable is not making it to Access or is empty. My procedure is meant to update a product record in the database.
Code: Private Sub btnChange_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnChange.Click Dim cmdOrderEntry As OleDb.OleDbCommand Dim strSQL As String
after click on save button the below mentioned error is ocuured Error: No value given for one or more required parameters. MOD EDIT: When posting code...USE CODE TAGS!!!
I have getting error while update the data to Access db from VB.NET. Which is shown "No value given for more required parameters". Here i have given the code what i have tried.....
con.open() dim a dim cd as new oledb.oledbcommand a="update inward set Quantity=" & textbox3.text & "Where tool_name=" & listbopx1.selectedItemm & "" cd=new oledb.oledbcommand(a,con) cd.ExecuteNonQuery() con.close
When I run the following code I get two errors. The first is when I try to save a new set of data it tells me there is a "Syntax error in INSERT INTO statement". The second is when I try to save an update in tells me "No value given for one or more required parameters". I'm not sure why this is happening as before I added in Contact Deatails it saved fine.
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
I'm trying to update an Access database by using an OLE connection, retrieving the information from textboxes where the user enters the new information.All the fields in my Access table are required fields, so I have validated that some info is entered in each one of the textboxes and that is the correct data type.But when I run the update query I get an error message saying something like values haven't been entered for some required parameters (my Visual Studio is the Spanish version, so I can't give the exact error message in English).The bit of code where the error occurs is inside the procedure called by my "Ok" button:
Dim campo1, campo2, campo3, campo4, campo5 As String Dim campo6, campo7, campo8 As Double Dim campo9, campo10 As Integer
[code]....
(I didn't post the whole code inside the procedure, but of course I'm creating the connection and everything)
The table has 10 fields, and the data is read from the textboxes and stored in variables (campo1, campo2, campo3, etc.), which I'm then using in the "set" query command.
"id" is the first field from the selected row in the datagrid, which I'm sending as a parameter to the procedure called by the "OK" button.The error message shows at runtime, so I'm guessing it's something in the query. Am I writing it correctly?
I have a remove button like i would like to delete just sigle selected row from both datagridview and the actual database.the problem I am having is in deleting selected row.if i dont use the parameter the contents of the table gets deleted ,i dont have any primery key just an ID field (AutoNumber).i am struggling with it for while .
I have a MS Access DB with a query that I need to display in vb but am not too sure on how to go about it. The query has some criteria - i.e you have to input a date to run the query. I think that's a parameter in vb......
Well I've been playing around with it for some time now but amn't really getting anywhere. Could ye recommend any good tutorial or link as to how to do it?
Here's the code that I've been working on:
Imports System Imports System.Data Imports System.Data.OleDb
[Code]....
I've been trying to reference the query as a dataset. But should I write the SQL code someplace??
Also, when I run it I get the error: "No value given for one or more required parameters"
What's wrong in here, I always get some nasty errors even if the same code that I used earlier works. But when I apply it to other form it gives me the error above. here's my code:
Imports System.Data.OleDb Public Class Updater2 Public adminID As String
I'm trying out something with my Access db and gets this recurring error message: "No value given for one or more required parameters", even though there is no parameter in my query. Here's my code (By the way I am using Northwind DB):
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click strSQL = "SELECT CompanyName FROM Customers" Dim con As New OleDbConnection(strCon) Dim cmd As New OleDbCommand(strSQL, con) [Code] .....
I am using a form which is having a listbox having a column of access table. When I select an item n press deleting it its working fine. But from the next time its showing an error "No value given for one or more required parameters".
Refer the ecode below: Private Sub load_listbox() Dim m_DataAdapter As OleDbDataAdapter Dim m_DataSet As New DataSet() Dim tbl_name As String = "Fld_detail_" & Datamaker.Application_Datamaker_ListBox.SelectedItem m_DataAdapter = New OleDbDataAdapter("SELECT Start_loc FROM(" & tbl_name & ");", [Code] .....
I am working vb.net08. Access Db. I am sending my below code for refference. Actually i am getting error when i am sending values from datatable to Temp Table in the Access Db. Error is : "No value given from one or more requaired parameters". In my datatable name called 'Crosstab1' few columns having text type and few columns having Value type. So i am getting error while i am Inserting values into Temp Table Called 'Official'. My Code is:
This is the error I am getting: System.Data.OleDb.OleDbException was unhandled ErrorCode=-2147217904 Message="No value given for one or more required parameters." Source="Microsoft JET Database Engine"
My code is : cmd = New OleDbCommand("SELECT [Employee] FROM [PhoneRecord] Where [PhoneNumber]='[(216) 370-1793]'", con) If con.State = ConnectionState.Closed Then con.Open() Dim sdr As OleDbDataReader = cmd.ExecuteReader() <~~~ERROR While sdr.Read = True User1.Text = sdr.Item("Employee") End While sdr.Close()
This was working fine yesterday, today all I did was change the database and its location as well as update all the dataset objects, and now its not working. The only thing I am thinking is that I didn't copy the database to the program directory, but I tried to copy it into there manually and I am still getting an error.
I am having error with the line of code. It prompts me with "No value given for one or more required parameters."

I am trying to returns records based on the last name of a customer in an access db. When I run the query in Access it works fine, the name in the examples returns 3 records with that last name. I use the same basic structure for other queries based on other fields (ID, UnitID etc) and they work fine.
