If you do not specify a code attribute, the code defined in the database system is used.

·        The code can be defined for particular users using appropriate SQL statements (for more information, see: CREATE/ALTER USER Statement or CREATE/ALTER USERGROUP Statement).

·        The code can be defined globally during the installation of the database system using the special database parameter DEFAULT_CODE.

The code defined for a user overrides the code specified globally in the database system.
