Use AJAX to watch SQL database for changes [closed]

Answer 1

Hook a special stored procedure into your database that alerts your application after a modification. You'll need a custom module and the right trigger statements.

Your other option is polling.

Answer 2

I'd suggest creating an HTML page that uses setIntreval() to repeatedly make AJAX calls to a PHP script that queries the your database. You could use JSON and PEAR to make the task a little easier.
