jquery - AJAX VS JSon "Cross Domain Built-in Security" Question -

-

It looks like I can not call "AJAX" outside of the existing domain name but I have jquery twitter API ( With JSON) I am able to call ... not using both the XMLHTTP objects? If this is (or not), why am I able to call another domain name with JSON (using JQuery), but not with AJAX? What is the difference between Ajax and JSON?

The Twitter API uses JSONP, which does not use XMLHTTPRequest, but the "foreign" JavaScript To include & lt; Script & gt; This script uses the tag then calls the function in its own JavaScript.

The Google Maps integration in third party websites will not be possible without this "hack" (this is exactly what it is: a hack).

Here is more information on JSONP:

Or in Wikipedia article on JSON:

oracle - The fastest way to check if some records in a database table? -

-
I have a big table to work with. I have to see that there are some records whose parent_id is equal to my passing value. Currently I do this by implementing "my_table using select count (*) where parent_id =: id"; If the result> 0, it means that they exist. Because this is a very large table, and I do not care what the actual number of records present, I just want to know if it exists, so I think count (*) Bit is disabled. How do I apply this requirement most quickly? I'm using Oracle 10. # Tips for Hibernation & amp; Tricks It suggests writing in such a way: Integer number = (integer) session .createQuery ("Select Count (*) to ...."). UniqueResult (); I do not know what is the magic of the unique rule? Why does it fast? To compare, select "1 from mytable where parent_id = passId and rowrum", which is more efficient? If you are not interested in the number of records, then there is an EXISTS query one: Select 'y'
