Subject: [Pljava-dev] Canceling row update in before trigger
Message-ID: <eca519a10912070443n5257e5cfiad4142d4e15b1327@mail.gmail.com>

Hi Everybody,

I'm looking for a method to cancel the row update/insert/delete as
returning NULL in PL/pgSQL would do.
I found a similar question on this mailing list archives (back in
2006) but haven't found any follow up.

Is there any way to do this?

Thanks in advance,
