How can I receive a notification whenever there are record in a database table?

Question

How do I get a notification whenever there is a record in a particular table in the database?

1. If I use a Trigger in MySQL will not work when I change database.

2. If I make an Ajax request every certain interval, I will make unnecessary requests and I've been punished for it in Hostmonster (escape them).

3. Another idea?

This guy went through the problem as me: http://www.schiffner.com/11-excruciating-months-with-hostmonster-have-come-to-an-end/

Thank you.

Answer 1

Sending Ajax requests at regular intervals (long polling) may not be the best solution but I have seen this implementation in many applications and probably it is easy to implement.

One of the solutions that has not been mentioned here is a PHP script running in a scheduler. This question will help you and make things clearer. Schedule alarm notification system php
