I've use VB as my front-end and oracle as my back-end.
I tried to use the program to purge data from 8i to 9i, all the while
there is no problem, but after sometimes, when i purge the data, it
will prompt this error message: "Out of present range".
Sometimes data has successfully moved to archive database, but some of
them still in the original database, when i tried to use query run in
the sql plus, it can successfully purged, don't know why system has
successfully purged, but no data has been moved. No error message
Anyone know what is the problem?
