Help with Ajax,Javascript -- 2

I need help with PHP-MYSQL-AJAX-JAVASCRIPT fom time to time.

This would be a get-paid to be a teacher type of project

and eventually maybe be a partner doing some projet part

or whole project.

Here is my problem:

I have a web page generated with PHP with a repport <div> on it.

the department manager want this repport to be refreshed every 5 seconds....

for maybe 5-10 person looking at it in real time.

the page it filled with content and by itself it makes maybe 20 to 30 MySql query

to output de page.

I am afraid that refreshing the page every 5 sec will load the Mysql Server with tons of similar request over and over....

I track the last change in a Mysql Table in [login to view URL]

then refresh only the repport table div if the returned value form the Ajax request have changed..

I tried different ways but my knowledge of javascript & Jquerry are insuffisant to make it work.

I don't kno how to store the return value of '[login to view URL]' and than 5 second later compare it to the new value of '[login to view URL]' en if changes then reload '[login to view URL]
