8. “ Drop user user_name CASCADE “
Drop user system privilege :
“ Drop user user_name CASCADE “
Specify CASCADE to drop all objects in the user's schema before dropping the user.
Specify CASCADE to drop all objects in the user's schema before dropping the user. You must specify this clause to drop a user whose schema contains any objects.
If the user's schema contains tables, then Oracle Database drops the tables and automatically drops any referential integrity constraints on tables in other schemas that refer to primary and unique keys on these tables.
If this clause results in tables being dropped, then the database also drops all domain indexes created on columns of those tables and invokes appropriate drop routines.
