where to make a DB request to save in DB all fields provided in registration

i want to store in a special table in DB all fields provided by the user (like phone and others)

i can't find the call to the DB and i wonder in which file the INSERT request to jos_users is done...
(i looked into com_user and com_ajaxregister)

Can anyone help?

AJAX Register is not component meant to add additional fields to registration. Maybe it will be supported in future but it's too big change to be supported now.

yes i understand...
I mean i just want to add in your code an sql query i need to make with some registration details...


in which file do i have 2put my query??
thank u for ur help.

You did not understand: it's not just that easy and I don't support that. Sorry.
