Question

I would like to duplicate some roles from a production database to a test database.

How can I programatically generate a text-based SQLPLUS script to do this? Since I’m only interested in the roles I don’t want to use EXP/IMP.

DBMS_METADATA might be helpful: http://www.orafaq.com/wiki/DBMS_METADATA

SELECT dbms_metadata.get_ddl('ROLE', role) FROM dba_roles;
SELECT dbms_metadata.get_granted_ddl('ROLE_GRANT',  '&&your_role_name') FROM dual;
SELECT dbms_metadata.get_granted_ddl('SYSTEM_GRANT','&&your_role_name') FROM dual;
SELECT dbms_metadata.get_granted_ddl('OBJECT_GRANT','&&your_role_name') FROM dual;
