USER

Syntax

Description of the illustration user.gif

Purpose

USER returns the name of the session user (the user who logged on) with the data type VARCHAR2. Oracle Database compares values of this function with blank-padded comparison semantics.

In a distributed SQL statement, the UID and USER functions together identify the user on your local database. You cannot use these functions in the condition of a CHECK constraint.

Examples

The following example returns the current user and the user's UID:

SELECT USER, UID FROM DUAL;
