Passe os parâmetros devidamente. Você poderia então personalizar sua saída.
DBMS_METADATA.GET_DDL (object_type, object_name, object_owner)
Por exemplo, para obter os METADATA para todas as tabelas no usuário SCOTT .
SQL> conn scott/[email protected];
Connected.
SQL> set long 200000
SQL> select dbms_metadata.get_ddl('TABLE',t.table_name, 'SCOTT') from US
DBMS_METADATA.GET_DDL('TABLE',T.TABLE_NAME,'SCOTT')

Então, isso me dá o DDL para todas as tabelas no SCOTT esquema.
Da mesma forma, você pode fazer o mesmo para todos os outros objetos como
INDEXES
, ROLES
etc. Para obter o DDL em um arquivo de texto, basta usar SPOOL . Portanto, você só precisa de scripts individuais para diferentes tipos de objetos para fazer o spool nos respectivos arquivos de texto.
