In the access database I have added one more column and I called this column iCounter with type Number. Then in put this in my code:
Using con As New OleDbConnection(ConfigurationManager.ConnectionStrings("TestLocal").ConnectionString)
Dim cmd As New OleDbCommand("SELECT [tblWorkOrderItem].WorkOrderItemID,[tblWorkOrderItem].bffGrade AS Item,[tblWorkOrderItem].Quantity AS Qty, [tblWorkOrderItem].Description, [tblWorkOrderItem].Note, [iCounter] FROM (tblWorkOrderItem INNER JOIN tblWorkOrder ON tblWorkOrderItem.WorkOrderID = tblWorkOrder.WorkOrderID) WHERE [tblWorkOrderItem].WorkOrderID=@ID", con) With {.CommandType = CommandType.Text}
Dim myParamCollection As OleDbParameterCollection = cmd.Parameters
Dim myParam As OleDbParameter = myParamCollection.Add(New OleDbParameter("ID", OleDbType.Integer))
myParam.Value = Convert.ToInt16(Session("ID"))
' Dim myICounter As OleDbParameter = myParamCollection.Add(New OleDbParameter("iCounter", OleDbType.Integer))
' myICounter.Value = 0
Dim selectResults As New DataSet()
Dim ole_DBAdapter As New OleDbDataAdapter(cmd)
ole_DBAdapter.Fill(selectResults)
con.Open()
If cmd.ExecuteReader.HasRows Then
GridView1.DataSource = selectResults
GridView1.DataBind()
End If
con.Close()
End Using
Problem if I add any column into the table and then put this new column in the query I get this error message:
System.Data.OleDb.OleDbException: 'No value given for one ore more required parameters."
However this is not to be placed in a Where condition this is just a column to be added into the table. If I remove this from the SQL query it is fine. But I need it because I want to be able to put some log string in the column. How do I go about resolving this issue?
Thanks in advance.

Hi xboxown,
Please Change your sql select query with below query.
SQL
SELECT [tblWorkOrderItem].WorkOrderItemID,[tblWorkOrderItem].bffGrade AS Item,[tblWorkOrderItem].Quantity AS Qty,[tblWorkOrderItem].Description,[tblWorkOrderItem].Note,[tblWorkOrder].[iCounter] FROM tblWorkOrderItem INNER JOIN tblWorkOrder ON tblWorkOrderItem.WorkOrderID = tblWorkOrder.WorkOrderID WHERE [tblWorkOrderItem].WorkOrderID=@ID

I did 100% exactly as you said and I still got the error message:
Continuation of the string
Even this failed
SELECT [tblWorkOrderItem].[WorkOrderItemID],[tblWorkOrderItem].[bffGrade] AS Item,[tblWorkOrderItem].[Quantity] AS Qty,[tblWorkOrderItem].[Description],[tblWorkOrderItem].[Note],[tblWorkOrder].[iCounter] FROM [tblWorkOrderItem] INNER JOIN [tblWorkOrder] ON [tblWorkOrderItem].[WorkOrderID] = [tblWorkOrder].[WorkOrderID] WHERE [tblWorkOrderItem].[WorkOrderID]

Check with the below code.
Using con As New OleDbConnection(ConfigurationManager.ConnectionStrings("TestLocal").ConnectionString)
Dim cmd As New OleDbCommand("SELECT [tblWorkOrderItem].WorkOrderItemID,[tblWorkOrderItem].bffGrade AS Item,[tblWorkOrderItem].Quantity AS Qty, [tblWorkOrderItem].Description, [tblWorkOrderItem].Note, [iCounter] FROM (tblWorkOrderItem INNER JOIN tblWorkOrder ON tblWorkOrderItem.WorkOrderID = tblWorkOrder.WorkOrderID) WHERE [tblWorkOrderItem].WorkOrderID=@ID", con)
cmd.CommandType = CommandType.Text
Dim myParamCollection As OleDbParameterCollection = cmd.Parameters
Dim myParam As OleDbParameter = myParamCollection.Add(New OleDbParameter("@ID", OleDbType.[Integer]))
myParam.Value = Convert.ToInt16(Session("ID"))
' Dim myICounter As OleDbParameter = myParamCollection.Add(New OleDbParameter("iCounter", OleDbType.Integer))
' myICounter.Val
con.Open()
Dim selectResults As New DataSet()
Dim ole_DBAdapter As New OleDbDataAdapter(cmd)
ole_DBAdapter.Fill(selectResults)
GridView1.DataSource = selectResults
GridView1.DataBind()
con.Close()
End Using
I have checked with the code and is working in my side.
