SQL & PL/SQL

Hi,

after trying the oracle documentation, I have to ask you now, folks. How do I change my session to support the UTF8 "Database" character set. That means, I want to be able to store UTF8 characters in normal varchar2 fields and don't have to change a thing on my database.

According to the documentation this should be possible through a kind of

alter session set nls_????='UTF8';

statement. Exactly this information is to me a lot too scattered in the documentation and I couldn't find it, so could any one of you help me find the right parameter?

Thanks a log in advance!
