The DROP VIEW statement removes a view created by the CREATE VIEW statement. The view definition is removed from the database schema, but no actual data in the underlying base tables is modified.
The view to drop is identified by the view-name and optional schema-name specified as part of the DROP VIEW statement. This reference is resolved using the standard procedure for object resolution.
If the specified view cannot be found and the IF EXISTS clause is not present, it is an error. If the specified view cannot be found and an IF EXISTS clause is present in the DROP VIEW statement, then the statement is a no-op.
