TOracleDataset eat duplicate key errors?

[donychao]

I don't know why TOracleDataSet eat
duplicated key errors and my users don't get
what happened to their data entres?
Did I miss out something to do with it?
I want to let them know what happened and
how should I do?

If you do "nothing special", your users will see an error. By default you will get an "ORA-00001 unique constraint (constraint name) violated" message, though you can use the TOracleSession.MessageTable to translate this to something more meaningful.

If you are using an event like TOracleDataSet.OnPostError, you may be able to hide the error.
