updating db with csv

[moishyyehuda at gmail.com]

#1 If any one familiar with godaddy hosting. They have apparently have
a hosing server i.e.(scripts, html files etc.), and a server for
databases. How can I import from my script,  with a csv. if the db is
on a different server than the script server.

#2 I would like to update and insert with the same csv file. Is there
a way to tell the database for some lines to update, and for some
lines to insert.
