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;
