I am not sure what you mean by a mysql datafeed. Usually, we deal with some server-side script, such as a PHP script that handles the MySql database. This works, there is no particular trick in this and you can find very many examples. So, allow me to assume you have a bug in your code and, since I can't see it, I can't help.

I believe there is a basic misunderstanding: no browser can communicate directly with a database server. You need a PHP script or some such server-side script that will receive the request from the browser, query the database and then reply with the results.

On the browser side, this example:

http://developer.yahoo.com/yui/examples ... rjson.html

is what you would be looking for, just up to line 23 in the code box, the rest shows how to add further requests.

The server side depends on what scripting language you have installed, most of them have JSON encoders either built-in or as an add-on.

It will certainly help if you read the tutorials in the YUI Blog, which are linked from the DataTable's front page.

Search for MySql rowset into json_proxy post on this Forum .

I have posted the code , see if it helps
