DATABASE VIEW NOTES:
  • Owner - Owner of the view
  • View Name - Name of the view
  • Created - Date/time view was created
  • Status - Status of the view

  • Views are virtual looks at tables. They don't exist until queried except as a specification statement stored in the database.
  • A single view can be very efficient, but the "stacking" of views, that is, views that reference views that reference views, can show a performance problem.
  • If you attempt to create a view using grants received from a role you will get an ORA-01933 error. You must have direct grants on all objects used in the view definition.
