    ' Update the demographics for a store, which is stored 
    ' in an xml column.
    Dim commandText As String = _
     "UPDATE Sales.Store SET Demographics = @demographics " _
     & "WHERE CustomerID = @ID;"

    Using connection As New SqlConnection(connectionString)
        Dim command As New SqlCommand(commandText, connection)

        ' Add CustomerID parameter for WHERE clause.
        command.Parameters.Add("@ID", SqlDbType.Int)
        command.Parameters("@ID").Value = customerID

        ' Use AddWithValue to assign Demographics.
        ' SQL Server will implicitly convert strings into XML.
        command.Parameters.AddWithValue("@demographics", demoXml)

            Dim rowsAffected As Integer = command.ExecuteNonQuery()
            Console.WriteLine("RowsAffected: {0", rowsAffected)
