db-objecten exporteren voor versiebeheer

Geef de parameters door naar behoren. U kunt dan aanpassen uw uitvoer.

DBMS_METADATA.GET_DDL (object_type, object_name, object_owner)

Om bijvoorbeeld de METADATA . te krijgen voor alle tabellen in de gebruiker 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')

Dit geeft me dus de DDL voor alle tabellen in de SCOTT schema.

Op dezelfde manier zou je hetzelfde kunnen doen voor alle andere objecten zoals INDEXES , ROLES enz.

Om de DDL in een tekstbestand te krijgen, gebruik je gewoon SPOOL . Je hebt dus alleen individuele scripts nodig voor verschillende objecttypes om in de respectieve tekstbestanden te spoolen.
