Angelo,
I don't have SDE installed on this local machine (perhaps I should look for docs on the install disk?), but searching on ESRI's support site is a hit or miss affair that only returns anything if someone else has posted something looking for answers on the same or similar codes. Often without an authoritative reply.
I've found the sdeerno.h file which explains _some_ of them.
ex:
db_array_fetch_spix_recs OCI Fetch Error (936)
db_array_fetch_spix_recs OCI Fetch Error (907)
db_array_fetch_attrs OCI Fetch Error (904)
I am assuming that there was an error in the "db_array_fetch_spix_recs" or "db_array_fetch_attrs" (i.e. that there was an error in a database array either fetching spix records or fetching attributes), that it was an "OCI Fetch Error" and that the number 936, 907, 904 is the type of "OCI Fetch Error" that occurred.
What exactly _is_ an "OCI Fetch Error" and what the numbers mean, I can't seem to find.
We are still on ArcSDE 9.3 and the link you provided was to 10.0, is there a similar link to 9.3?
Thanks again.
