Size specification | SizeSpecification | Specifies whether the tablespace is a bigfile or smallfile tablespace. This clause overrides any default tablespace type setting for the database. You can choose from the following settings:
|
Temporary tablespace | Temporary | Use this option to create a locally managed temporary tablespace, which is an allocation of space in the database that can contain transient data that persists only for the duration of a session. This transient data cannot be recovered after process or instance failure. |
Undo tablespace | Undo | Use this option to create an undo tablespace. When you run the database in automatic undo management mode, Oracle Database manages undo space using the undo tablespace instead of rollback segments. This clause is useful if you are now running in automatic undo management mode but your database was not created in automatic undo management mode. |

Object view type | ExtObjViewType | Defines the type of the object view. |
Force | ExtViewForce | When set to TRUE, allows you to create the view regardless of the existence of the base tables or the owner privileges on these tables. |
