I was needing to extract DDL for all tablespaces on Oracle Database . Then, I took the information about it using a DBMS_METADATA. Thus, follow how to take this information: SQL> set heading off; SQL> set echo off; SQL> set pages 2000 SQL> set lines 2000 SQL> set long 99999 SQL> spool ddl_tablespaces.sql SQL> select dbms_metadata.get_ddl(‘TABLESPACE’, tablespace_name) from dba_tablespaces ; ##HERE WILL BE SHOWN ALL TABLESPACES DLL ABOUT YOUR DATABASE## SQL> spool off I hope this post can help you! brunors
