advertise “native” error code, then it should just be the code
returned by the underlying server. Yes, that will be different for different
providers. I’m also concerned about client applications writing a lot of
provider specific code, but I do understand that there will be cases where
applications will want this information and we should just pass it through. As
someone mentioned in a related thread, this is consistent with other data
access API’s out there.<o:p></o:p></span></p>

<p class=MsoNormal><span style='font-size:12.0pt;color:#1F497D'>No, they
don’t. This is my point, e.g. OCIDR_RDBI_END_OF_FETCH can be mapped to
RDBI_END_OF_FETCH and such type of error is common to SQLServer, MySql etc. I
suppose it’s not a crime to also have RDBI_ORA_xxx for specific cases

<p class=MsoNormal><span style='font-size:11.0pt;color:#1F497D'>My main concern
is that having native error codes encourages the client code to be non-generic,
in that it would have to know which provider it is working with, in order to
handle the native error code correctly. Of course, that is a concern about the
client code, not FDO itself, so the client code is free to handle this any way
it wants… including in bad ways.<o:p></o:p></span></p>
