Hi Richard Huxton,
Thank you for your kind response.
Is there not any other way other than record the pkey in a
"process_these" table and have the application check there. We want
to minimise the database transactions to improve the DB performance.
Can we send the exact data which has been changed using
db-notify to the application? So that, the application can continue
processing the data using the Notify message from the DB.
Thanks in Advance,
Ramachandra B.S.

Afraid not. You'll need to record the pkey in a "process_these" table
and have the application check there.
