ORA-03001: unimplemented feature


I have a table abc in scott user. I need to rename it to xyz.

When I execute the below command in scott user,
RENAME abc TO xyz.
it got successfully executed.
But when I execute in SYS user as below
RENAME abc TO xyz.

I am getting the below error.
ORA-03001: unimplemented feature

Can you please let me know how can overcome this?

Because I need to give this script to DBA who executes as sys user.

The documentation for RENAME states that the object being renamed must be in your own schema.  It seems a little vague, but I am guessing based on the message you received is that it has to be in the schema you are connected to.  Changing current schema doesn't seem to work on that.  The alternate syntax that should work as SYS (at least it did when I tried it) is:


NOTE:  That does not change the owner of the table, just the table name.

I am getting the error when I specify the owner name before the table name as below
ORA-01765: specifying owner's name of the table is not allowed

I get that when I use:


Not when I used the ALTER TABLE syntax that I posted.

I could achieve as
create table xyz as select * from abc;
and creating all the constraints and dependents on abc to xyz manually and then
drop table abc;

You could also do it as:

create procedure fia.rename_table
  execute immediate 'rename abc to xyz';
exec fia.rename_table;
drop procedure fia.rename;

DBAs shouldn't be connecting as the SYS use to do these kinds of things anyway.  Definitely an auditing failure.  Everywhere I have been DBAs would connect as the schema owner to make any kind of structural changes.  They should be the only ones that know the password anyway.

Sorry. I used wrongly.

When I use with alter I did not get the issue.

Thank you very much for the help.
