Universal, and works with 7.3.4 - which is still in common use - but is deprecated in favour of:

        select sid from v$session where audsid = 
            sys_context('USERENV', 'SESSIONID' );

which still doesn't help if you have several SYS sessions running, as the sessionID for SYS is always zero.

The v$mystat option is the newer 'universal' except there is a preferred call to dbms_support.mysid (on the platforms which have, and have installed, dbms_support (dbmssupp.sql) - and the package only does a

select sid from v$mystat where rownum = 1; anyway.

I believe

select sid from v$session where audsid = USERENV( 'SESSIONID' );

is a universal way to determine one's current internal SID based on the sessionid returned by userenv.
