How to show a loading icon during a long query of a DB?

Experts,

I have an sql query that takes some time to execute due to the size of the database and complexity of the query.  Is there anyway to show a loading graphic while this query is doing it's thing?

Cheers!

As far as I am aware there is not via PHP. You could, however, use AJAX to execute the query and return a JSON/XML confirmation when it has succeeded and show a loading graphic that way.

jQuery (jquery.com), a popular JS library, has some very easy to use AJAX functions with customisable start (when ajax starts) and completion (when the ajax request is completed) functions -- ie, when AJAX starts, display a loading graphic and when it stops you hide the graphic.

Obviously with this method your page needs to load in order to start the AJAX request and you'll need to verify the success/failure based on the JSON/XML response.

You must use a javascript library, I use mootools, you just need to add a onRequest and oncomplete event, to an HTML Request.

Google "jQuery Progress Bar" and you may find some good stuff.  You might also consider using just a little bit of CSS to style the "loading" message.  When the page completes, you could hide the message with a bit of JavaScript to modify the CSS.

I am currently using Prototype to handle my ajax requests.  I was able to use Prototype to do what I needed to do.

Thank you for your suggestions, I am sure that each of them are viable in there own ways.

Points to all.  Cheers!
