Hi all

Few days back i run a yql from my application on ip.location (community table) to get the details of ip and it worked fine for both XML content as well as J SON
but it is giving error like
Cannot load an external table environment file from http://datatables.org/alltables.env No definition found for Table ip.location

where my query is :
http://query.yahooapis.com/v1/public/yql?q...2Falltables.env

But i am able to get the data from upcoming.events table which is a non community table

Please clear my questions:

>> why ip.location table is not identified

>> what are community tables

>> <select usesRemoteLimit="true"> what does it mean

help is appreciated
