Because data dictionary tables can change, views provide greater stability.
In Unicode views, object names are returned in the session character set. The substitution character for the session character set is returned for any characters in the object name that do not exist in the session character set.
- view_name V
- view_name VX
For example, All_RI_ChildrenV or All_RI_ChildrenVX, where the “X” denotes a partial view that omits certain restricted data, such as security-related information.
