title: OracleCommand Update does not commit changes
body: <p>I am using the following code to update a table in oracle. It executes but the update does not commit. If I run the query with Oracle SQL Developer it works fine. What am I missing? SELECT statements work as expected.</p>
  
  <p>`Dim BillOfLadingNumber As String = txtBillOfLadingNumber.Text.Trim</p>
  
  <pre><code>    Dim TrailerNumber As String = txtTrailerNumber.Text.Trim
      Dim CarrierCode As String = txtCarrierCode.Text.Trim
     Dim TransportationMethod As String = txtTransportationMethod.Text.Trim 
     Dim OracleCommand As New OracleCommand()
      With OracleCommand
          .Connection = OracleConnection
          .CommandType = CommandType.Text
          .CommandText = "UPDATE XXF_ASN_HEADERS SET BILL_OF_LADING_NUMBER ='" + BillOfLadingNumber + "',TRAILER_NUMBER ='" + TrailerNumber + "',CARRIER_CODE ='" + CarrierCode + "',TRANSPORTATION_METHOD ='" + TransportationMethod + "' WHERE HEADERID ='" + Request.QueryString("HeaderId") + "'"
      End With
  
      OracleConnection.Open()
      Dim result As Integer = OracleCommand.ExecuteNonQuery()
      OracleConnection.Close()
  
      If result = 1 Then Response.Redirect("default.aspx")`
  </code></pre>
