I'm trying to get support for PostgreSQL's listen/notify into a development environment, but since it supports multiple database backends: can anybody comment on how many other servers have a comparable facility? Minimal research has allowed me to code something for Firebird/Interbase, but I'm not in a position to investigate Oracle, IBM, MS and the rest. I'd appreciate any general comments from somebody who has broad SQL experience, I'm not asking for example code.
For Oracle this would be the "change notification" feature which goes beyond what Postgres can do if I'm not mistaken as you can register a query and the client is notified if the result of that query would change: http://docs.oracle.com/database/121/JJDBC/dbchgnf.htm#JJDBC28815 -- Sent via pgsql-general mailing list (pgsql-general@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
