PLSQL, SQL*PLUS get current username?

Question

I know that the show user command return: USER is "SCOTT"

But is it possible in a sql query or in a plsql script to only get the username of the current user and store it in a variable?

Answer 1

The USER built-in function may be used.

DECLARE
  v VARCHAR2(30);
BEGIN
  v := USER;
END;

Answer 2

SYS_CONTEXT( 'USERENV', 'CURRENT_USER' )

Answer 3

fnd_profile.value('USERNAME')
fnd_profile.value('USER_ID')
fnd_flobal.user_id

these can be used to get the user details
