SQL Update Query Returns Error Message Saying Not All The Parameters Have Been Set?
Jul 8, 2010
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 problem regarding to my Update data the message error show Syntax error near set LastName I already check my code but i dont know what is the error this is my code:
Dim sqlcmd As New SqlClient.SqlCommand With sqlcmd.Parameters .Add(New SqlParameter("@Id", lblid.Text)) .Add(New SqlParameter("@LastName", txtlastname.Text)) .Add(New SqlParameter("@FirstName", txtfirstname.Text)) [Code] .....
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.
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
I am using VB2005 an I am using MS Access 2003 as a database, I am trying to update a table and I am getting the following error message when getting to the following line of
command.ExecuteNonQuery()]
This is the error taht I am getting:{"Data type mismatch in criteria expression."}Here a sample of my code
testsearch_connection = New OleDb.OleDbConnection("Provider=Microsoft.Jet.OLEDB.4.0;Data Source=C:CesarAccessdatabase.mdb;Persist Security Info=False") Dim command As New OleDb.OleDbCommand("UPDATE CallLog SET Priorityid = '" & CmbEditPriority.Text & "', Statusid = '" &
I keep getting the error shown in the screenshot below.To me it's saying that I haven't established the "UpdateCommand" property for the DataAdapter. However,I have established it as well as the "SelectCommand", "InsertCommand" and "DeleteCommand".All of these are created within a Class Module.I created a Class for the "tblControl" table that is is referencing. This class contains all the properties for this table as well as calls for "inserting", "updating", "selecting" and "deleting" records.I have attached a class.vb file so their is a clearer understanding. The highlighted line of code below is where I'm receiving this error message.[code].....
I'm receiving this message while trying to add a NEW client record as well as a NEW client Address record to the database. This portion works fine. I get the error message when I try to UPDATE the tblControl table with the new ClientID. The below code is where I do the inserts and update.By the way, I actually execute the "control.ControlOleDbCommands()", which establishes the adpControl DataAdapter Commands, when the program starts.[code].....
process is user selects a gridview item it redirects them to the update page and using a datareader, fills the text boxes and check boxes based on the id passed in the url the user can then make their changes to the text boxes/ check boxes and then press the update button which runs the update query. what i have found is happening is that although a user might change the text, when they submit the changes, the update query is still using whatever was loaded into that text box by the data reader on the page load. Here is the code below:
Protected Sub SubmitBTN_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles UpdateBTN.Click Dim tiresdim As Integer = 0 If TiresCHK.Checked = True Then
I know I've banged heads with this error before, but before the reason was because of my IMEX setting. This is the reason why I made two connections to the spreadsheet, one that uses IMEX=1 for the SELECT query and one with that option removed for the UPDATE / INSERT queries. So now I'm stumped why this is breaking in the following [code].....
Is there an issue with trying to open the same spreadsheet with two connections (I thought I had done this before)? Or some other issue that is causing this error to be thrown? BTW, I'm using this in a vb.net program so I don't think the issue is related to the security issues that asp users usually face with this error... On the other hand, I'm also on Win 7 and I know that its security is much tighter than on XP where I've used other programs that also update an Excel spreadsheet. I wouldn't think so, but would I have to run this in administrator mode in order to update the spreadsheet?
When I try to add an Update query, then open the Query Builder, I get an error saying: Error in table name or view name in UPDATE clause. Unable to parse query text. The only code that is in the Query Builder is UPDATE How would I fix this? If this is needed, the table name is Authentication, column names are AuthKeys, and Available.
Dim con As New OleDb.OleDbConnection Dim com2 As New OleDbCommand Dim constring As String = ConfigurationManager.ConnectionStrings("esourcecon").ConnectionString con = New OleDbConnection(constring) com2 = New OleDbCommand("UPDATE Customer SET CName = @CName, CAdd= @CAdd, CTel= @CTel, Cmob= @CMob WHERE CName='" & C1.Text & "' ", con)

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?
I have a postgresql database, one table. This table has a date column too.And I have this code:
[code]...
The problem is, that the pgreader returns no rows (the parameters are right and the database contains the data too).firstday and lastday are f.e. '2005.05. 01.', the ConvertDate function converts the date to '2005-05-01' (the dates are storen in this form in the database)And when the commandtext="select * from arfolyamok where datum between '2005-05-01' and '2005-05-31'", then it works, the pgreader has the rows.Why? What make I wrong?
I've created a custom MessageBox (a Form), that has buttons Yes and No. There is a function popUp() to show the MessageBox. I would call the MsgBox in a parent as follows: CustomMessageBox.popUp()
Now I want the message box to return a value: Dim a as Intger = CustomMessageBox.popUp() But this should only return once the user clicks a button in the message box.
My popup sub: Dim thread As New Threading.Thread(AddressOf GetResult) Public Function PopUp(Optional ByVal ErrorMessage As String = "", Optional ByVal Title As String = "", Optional ByVal ButtonType As ButtonType = ButtonType.OK, Optional ByVal MessageType As MessageType = MessageType.None) [Code] ..... gotResult is a Boolean = false. It the user clicks a button gotResult is changed to true. result is a integer containing the number of the button clicked.
When I run this code, the result is returned, even if the user doesn't click a button. I understand why, because the main thread of the form is not "paused" while the user has not clicked a button. How can I pause the message box itself, until a button was clicked? I've tried this:
Public Function PopUp(Optional ByVal ErrorMessage As String = "", Optional ByVal Title As String = "", Optional ByVal ButtonType As ButtonType = ButtonType.OK, Optional ByVal MessageType As MessageType = MessageType.None) [Code] .....
But now the whole message box is captured in a loop and the message box is like disabled, because it waits for the loop to end, so the user can't click anything.

how can write code that can check if __InstanceCreation query has returned rows or not. I'm using this code to check for the creation of a file
Private Function CheckForFileCreation() As Boolean Try Dim query1 As New WqlEventQuery( _
[Code]....
so I need to know if the query returned > 0 rows, if it did then the function will return true, if the query returned 0 rows then the function should return false. Sorry I am a complete noob with WMI and WQL
I am using the OLEDB adapter (Oracle OLEDB) with Oracle 10.2.0.3.0. My code generates the SQL for the query, then when I execute it into an OLEDBDataReader, the HasRows is False. However, if I output the contents of the query string, copy, and paste into SQL+ (logged in as the same user from the same client machine), it returns 993 rows. What gives?? Here's a segment of my code:
I've converted an html to XML and now i want to get all the child nodes nested within a DIV element with a specific attribute (class="itemInfo").Because the html that the XML is based on changes from time to time i want to use a more "safe" relative root, (something like : "//div[@class='itemInfo']").Problem is that i always get 0 nodes ...
Dim doc As New System.Xml.XmlDocument() doc.Load("products.xml") Dim root As System.Xml.XmlElement = doc.DocumentElement
Dim l as IList(Of Foo) = (From dataRow As DataRow In table.Select() Where CStr(dataRow("Column1")) = "A" Select New Foo(CStr(dataRow("Column1")), _ CStr(dataRow("Column2")))).ToList()
What's happening is that if i set a break-point to the constructor of Foo and step, the constructor is hit and the parameters are loaded with the arguments. However, l has empty Foo objects (the members in every object are Nothing). What could be happening here?
This is my first time using the Entity Framework and I'm getting some confusing results. I know a particular table contains 3 distinct rows when I run this SQL query: SELECT * FROM mytable WHERE service_month = 201012
When I run this query against the framework however, I get 3 rows, but they are all copies of the first row (VB syntax). Dim temp = _context.mytable.Where(Function(x) x.service_month = 201012) Did I set up something incorrectly? This is how I'd do it with LINQ to SQL.
I am trying to perform a query on an Access 2007 Database Using Visual Basic 2008. My database has a table tblStudents contains a field named Gender with Male/Female options. In VB 2008 I set up a form with a Combo box where the user can select either Male or Female to perform a query and navigate through the returned results. When i choose the 1st option in the Combo box the results are returned in the order. However when i choose the 2nd option in the combo box, i get the results in reverse order which i still could not find the reason why it does that. Here is my Code for the query and the Execute Query Button:
Private Sub DisplayGenderData(ByVal gender As String) connUsers.ConnectionString = "Provider=Microsoft.ACE.OLEDB.12.0;Data Source=C:StudentRecords.accdb;Jet OLEDB:Database Password=testing;" ' Open the connection.
how to create an error message by message box to tell the user to enter a number only if they key in a character value?
I MEAN AFTER THEY PRESS THE CALCULATE BUTTON
Private Sub btnCalcFat_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnCalcFat.Click Dim intFat As Integer intFat = Integer.Parse(txtFat.Text) lblResultDisplay.Text = txtFat.Text * 9 End Sub
I have a select statement which was returning the required values but when I changed the OS date from English(US) to English(UK), it now returns null. I believe the problem is concerned with date since in the query am selecting values where the date from the database is the same as the date in a combobox but I don't know what else I can do. It almost looks like the dates in the combox and in the database are not the same and yet the date in the combobox is actually retrieved from the database and has been returning values fine until I changed the system date format.Here's my select command:
cmd4.CommandText = _ "SELECT sum(brought_qtty), recieved_qtty from brought_coffee, centre_weigh where brought_date=#" & _ dtComb.Text.Trim & "#" & _[code].......
