The view must be in your own schema or you must have the
VIEW system privilege.
Specify the schema containing the view. If you omit
schema, then Oracle Database assumes the view is in your own schema.
Specify the name of the view to be dropped.
Oracle Database does not drop views, materialized views, and synonyms that are dependent on the view but marks them
INVALID. You can drop them or redefine views and synonyms, or you can define other views in such a way that the invalid views and synonyms become valid again.
If any subviews have been defined on
view, then the database invalidates the subviews as well. To determine whether the view has any subviews, query the
SUPERVIEW_NAME column of the
DBA_VIEWS data dictionary views.
CONSTRAINTS to drop all referential integrity constraints that refer to primary and unique keys in the view to be dropped. If you omit this clause, and such constraints exist, then the
DROP statement fails.
Dropping a View: Example The following statement drops the
emp_view view, which was created in "Creating a View: Example":
DROP VIEW emp_view;
