Smart Phone ! Iphone | Reading the device phone number HTTP etc -

-

Does anybody know if one of these devices is connected to the Web or not, its phone number is the header or Can be read by any other medium?

Phone numbers do not go into HTTP headers Your IP address will be visible to the web server, but it is.

EDIT: Ah, I want you want to get a phone number This is a privacy issue for many people and the consensus is that the slight inconvenience to clearly mentioning a phone number is worth the peace of mind that someone is not stealing it.

What you can do is for the user to number, and store it with the UDID in the phone of the database. The next time your app connects to your server, you can send it to the phone's UDID and view that number.

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'
