How to create a user with a particular user_id? Is it possible to specify the user_id of a user while creating it?

SQL&gt; create user user1 identified by user1;

User created.

SQL&gt; select user_id, username from all_users where username='USER1';

   USER_ID USERNAME
---------- ------------------------------
        72 USER1

SQL&gt;


Instead of 72, can it be a number that I specify?
Not in a supported fashion, no.

Why would you care what the USER_ID of a new user was?  That would seem to raise a pile of red flags in my mind.
