What characterizes a view compared to a temp view?

The characteristic that distinguishes a regular view from a temporary view is that a view reflects changes in the underlying tables. This means that any updates made to the data in the tables that the view is based on will be automatically reflected in the view itself. When you query a view, you are essentially querying the current state of the underlying data at that moment. This feature is crucial for ensuring that the information retrieved through the view is always up-to-date, reflecting real-time changes in the database.

Conversely, a temporary view is designed for a more transient purpose and is not intended to be used as a permanent structure. Temporary views are session-based and exist only for the duration of a session or until they are explicitly dropped, and they do not persist data to disk. They enable quick, ad-hoc analyses without affecting the underlying data structure or the database schema. Additionally, temporary views do support SQL access, but they are limited to their session duration and cannot be accessed outside of the session they were created in. Thus, the distinguishing feature resides in the ability of a view to automatically adapt to changes in the data it represents.
