Sql - Parameterized Query Expects The Parameter Which Was Not Supplied?
Oct 5, 2010
im having a problem with my code Private Sub TextBox2_TextChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles TextBox2.TextChanged
once i typed in the string in the textbox to search for an item i get this error The parameterized query '(@Parameter1 nvarchar(4000))SELECT * FROM borrow where (Departme' expects the parameter '@Parameter1', which was not supplied.""
I'm getting the error: The parameterized query(@CustomerID, @ProductCode, @DateOpened) expects the parameter @ProductCode, which was not supplied.For one thing, my INSERT query has five parameters, not just the three listed in the error notice.
Another thing, I supplied @ProductCode in the AddWithValue statement. Another thing is that I don't get the error when I change: InsertCommand.Parameters.AddWithValue("@DateOpened", Date.Today.Date)
I have an xbap application that calls a webmethod from a web service that executes a stored procedure and I'm getting the error that my stored procedure expects a parameter which was not supplied. Error and code are as follows
I am trying to execute a procedure from vb 2005 .The procedure has a return status that is returned to another procedure that writes an error log. The @status parameter has nothing to do with the app. Since @status is an output parameter what do I need to do?
I was working on this thread in regard to DataRelations on multiple tables. If I use CommandType = CommandType.Text, the code does as expected. However, I decided to take the SQL query and throw it into a stored proc. I then changed my code to use the stored procedure and I get the error as per the title of this thread.
When I use the SQL Profiler, I see that NULL is being passed to the stored procedure. I have looked online and haven't been able to find an answer.
When I use the Execute Query button in the Tableadapter Query Builder, the query works fine; I get all the rows I expect. However, when I run this in my code, the query behaves like an equality statement (i.e. Lotnumber = @Lotnumber) rather than a LIKE statement (Lotnumber LIKE '%' + @Lotnumber + '%').Here is the code that is not behaving correctly. Note that I have a textbox, LotSearchTextbox, where I enter the portion of the Lotnumber that I want to use as the filter. I also have a button, LotSearchButton:
Private Sub LotSearchButton_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles LotSearchButton.Click Try Dim SomeNumber As Integer = Me.LotCalcinerO2TableAdapter.FillByLotNumber(Me.CalcinerDBDataSet.LotCalcinerO2,[code].....
why the query works in the Query Builder but not in the code?
In my project I need to log all queries executed against my database. As an example we can use the staff user data here. In that class I have a function generating the command with the parameters as follows:
statement = "SELECT OrderID, (SELECT VendName FROM Vendors WHERE Vendors.VendorID = Orders.VendorID) " & ",OrderDt, RcvdDt, OrderTotal " & "FROM Orders " & "WHERE VendName=? " & "ORDER BY OrderDt DESC" Dim cmd As New OleDbCommand(statement, connection) cmd.Parameters.AddWithValue("VendName", txtVendorFilter.Text) Dim reader As OleDbDataReader = cmd.ExecuteReader(CommandBehavior.Default)
I was trying to do this before by simply concatenating the textbox value right into the SQL and I was getting a "No values given for required parameters", and read that that I should use parameterized queries instead. So I tried this and it doesn't give me any errors, but the reader never has anything in it. I've never used parameterized queries before, so I'm a bit lost as to why this isn't working. I've changed the above code to account for OLEDB from what I briefly read on how it should work, and it's giving me the "no values given for required parameters" again.
I solved this issue in this thread but there still are issues with special chars. ie 'I thought by doing parameters that it would take care of any special chars for you. Well i am still getting mysql exceptions about syntax. I look at the string it is working with and it has a "'" in it.Why are they not working as I expect them to?
As you may have seen in my other post, I have to switch over an all text SQL statement based database interaction program to using parameterized queries instead.I remember doing it this way in college but I don't seem to be able to recall one part of it. The program I wrote back then and some code samples here both point to doing the code as I did so far:
m_strSQL = "UPDATE [OWNER DATA] SET [FIRST NAME] = @strFName" m_strSQL &= ",[LAST NAME] = @strLName" Dim upCMD As New OleDb.OleDbCommand(m_strSQL, m_Connection) upCMD.Parameters.Add("@strFName", OleDb.OleDbType.Char, 30, "[First Name]")
it ran the SQL statement and that's that. Can I just do that with a parameterized query too without using the adapter.update()? And for bonus points, why the heck did I use that command in my old college program cuz I sure don't know?
I wrote this little function to allow me to pass an ArrayList of Strings and then based on the table passed to pre-build a SQLCommand like so INSERT INTO table` (`column`,`column`) VALUES (`value1`,`value2`);
The function for this is here: Public Function _SQLInsertBuilder(ByVal values As ArrayList, ByVal Table As String) As String Dim commandString As String Dim columns As ArrayList = GetTables(Table) commandString = "INSERT INTO `" & Table & "` (" For Each column As String In columns [Code] .....
Now I know that much like mysql_real_escape_string() VB.NET has a Parameter ability to make querys safer. How could I parameterize the values during the build of the string.
[code]Myself and a coworker have stared at this quite a lot and we can't figure out why it's not working. The problem is in the value for @ID (since it still works when I leave the other one parameterized). The funny thing is, Just a few lines of code above it I have a different query that sets a parameterized value for the same ID, using the the same choices list that the For Each loop is getting the match variable from.Choices is a list of longs, and when I use choices(0) to parameterize ID in a query, it works. But now down here in this loop I have the new match long, and it doesn't want to make it work for me.
I am connecting to an Access database and using a parameter query with the LIKE operator to return all rows that match query. The string to search for is taken from a Textbox
"Select * FROM Allview WHERE Info Like" & "*" & CStr(TextBox1.Text) & "*" The query does not return any data in vb, but when run from access with same string, there is data returned.The connection to the database is done correctly, as I am able to return data with various other queries.

I am trying to run a query an Access db from VB. The general query which I want to run is
SELECT * FROM Patient WHERE Patient.PatientID = ? or SELECT * FROM Patient WHERE Patient.PatientLname = ?
I tried using an input box which captured the user input and pass that variable to the query, but that failed. Then I read about writing a function and using that, however, I keep getting an error which says Function not defined, but when stepping through the code, it seems to work. Here is my function: [Code]
I wrote this code and i can populate result of query to combobox1.but i want to use parameter in my query and i want to range next combobox(such as combobox2) in attention to the selected item in combobox1.My sample databese name is test1 and has 3 field:categoryID,ParentID and Title.
I'm stumped here - the folowing code errors with Procedure or function 'importsp_CreateDiallerBatch' expects parameter '@BatchName', which was not supplied[code]...
When debugging the code, BatchName definitely has a value, and checking the parameters collection of cmd right before executing the urey shows 2 params, both named and with values set exactly as expected. I must have written code like this a thousand times
I am trying to load a combo box based on a selection of data from another combo box. I am not sure how I would pass the value to the object. My thought is I am loading all the table data onto my object and then I would run the query on the object. However I am at loss as to how I would go about doing that.

I have a query in a myTableAdapter that ends with WHERE column IN (@S). This works fine when I use myTableAdapter.Fill(dataset.table, "text") but I can't find any way that works to provide multiple text strings such as "text1, text2" for the IN parameter.
