-------------------------------------------------------------------------------
The information in this article applies to:

- Microsoft Visual Basic Enterprise Edition for Windows, version 5.0 
- Microsoft ODBC Driver for Oracle (Build 2.06325), version 1.0 
-------------------------------------------------------------------------------

SYMPTOMS
========

Using Remote Data Objects (RDO) ADDNEW and UPDATE method to create and commit
new records with the Microsoft Oracle ODBC driver may result in the following
error:

  Run-time error '40002':
  S1C00: [Microsoft][ODBC driver for Oracle]Driver not capable.

CAUSE
=====

Microsoft Oracle ODBC Driver version 2.00.06325 does not support this
functionality in conjunction with certain CursorDrivers.

RESOLUTION
==========

Choose a CURSORDRIVER of either rdUseClientBatch or rdUseODBC if Microsoft
Oracle ODBC Driver version 2.00.06325 is used.

Otherwise, obtain the latest version of Microsoft ODBC driver for Oracle that is
shipped with Microsoft Data Access Components (MDAC) 1.5c or MDAC 2.0. The
current version of the Oracle ODBC driver is 2.573.2927 and it supports this
functionality.


STATUS
======

This behavior is by design.

================

Steps to Reproduce Behavior
---------------------------

1. Start Visual Basic 5.0 Enterprise Edition.

2. Create a new Standard EXE. Form1 is created by default.

3. Add "Microsoft Remote Data Objects 2.0" to the Project References.

4. Add the following code to the new form's Load method:

        Dim rs As rdoResultset
        Dim cn As New rdoConnection
        cn.CursorDriver = rdUseClientBatch
        cn.Connect = "dsn=<dsn>;uid=<uid>;pwd=<pwd>"
        cn.EstablishConnection
        cn.Execute "CREATE TABLE temp1 (id int, name char(20))"
        cn.Execute "CREATE UNIQUE INDEX temp1_id on temp1 (id)"
        cn.Execute "GRANT ALL ON temp1 TO PUBLIC"
        cn.Close

        On Error GoTo Erh

        For i = rdUseIfNeeded To rdUseClientBatch
           cn.CursorDriver = i
           cn.EstablishConnection
           Set rs = cn.OpenResultset("select * from temp1", rdOpenKeyset, _
           rdConcurRowVer)
           rs.AddNew
           rs(0) = i
           rs(1) = "Also works fine"
           rs.Update   '<-- Errors occur here
           cn.Close
        Next
           cn.EstablishConnection
           cn.Execute "DROP TABLE temp1"
        End

        Erh:
           sterr = Error & Chr(13) & "With CursorDriver "
           Select Case cn.CursorDriver
              Case rdUseServer
                 sterr = sterr & "rdUseServer"
              Case rdUseOdbc
                 sterr = sterr & "rdUseOdbc"
              Case rdUseNone
                 sterr = sterr & "rdUseNone"
              Case rdUseIfNeeded
                 sterr = sterr & "rdUseIfNeeded"
              Case rdUseClientBatch
                 sterr = sterr & "rdUseClientBatch"
              Case Else
           End Select
           MsgBox sterr
           Resume Next
        End Sub

5. Run the Project and note that the Update fails with the error mentioned
  earlier.
