Can't change user profile

[Remo Laubacher]

When I try to change the user profile to "SYSTEM USER" I get an error.

The reason for that is quite simple. PL/SQL Developer tries to execute this query:

-- Modify the user
alter user MMAGLRE
  profile SYSTEM USER;

In fact it would be better to execute something like that:

-- Modify the user
alter user "MMAGLRE"
  profile "SYSTEM USER";

Best regards,
