Skicka parametrarna ordentligt. Du kan sedan anpassa din produktion.

DBMS_METADATA.GET_DDL (object_type, object_name, object_owner)

Till exempel för att få METADATA för alla tabeller i användaren 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')

Så detta ger mig DDL för alla tabeller i SCOTT schema.

På samma sätt kan du göra samma sak för alla andra objekt som INDEXES , ROLES etc.

För att få DDL i en textfil, använd helt enkelt SPOOL . Så du behöver bara individuella skript för olika objekttyper för att spoola in respektive textfiler.
