### Description
`DROP VIEW` removes the metadata associated with a specified view from the catalog.
### Syntax
```sql
DROP VIEW [ IF EXISTS ] view_identifier
```
### Parameter
* **IF EXISTS**
If specified, no exception is thrown when the view does not exist.
* **view_identifier**
Specifies the view name to be dropped. The name may be optionally qualified with a database
name (or a catalog and database). A name qualified with `session` or `system.session`
targets a temporary view.
**Syntax:** `[ catalog_name. ] [ database_name. ] view_name`
### Examples
```sql
-- Assumes a view named `employeeView` exists.
DROP VIEW employeeView;
-- Assumes a view named `employeeView` exists in the `userdb` database
DROP VIEW userdb.employeeView;
-- Assumes a view named `employeeView` does not exist.
-- Throws exception
DROP VIEW employeeView;
Error: TABLE_OR_VIEW_NOT_FOUND
-- Assumes a view named `employeeView` does not exist,Try with IF EXISTS
-- this time it will not throw exception
DROP VIEW IF EXISTS employeeView;
-- A temporary view that shadows a persistent view with the same name.
-- An unqualified DROP VIEW drops the temporary view first; qualifying with `session`
-- always targets the temporary view explicitly.
CREATE VIEW default.recent_orders AS SELECT * FROM orders WHERE order_date > current_date - 7;
CREATE TEMPORARY VIEW recent_orders AS SELECT * FROM orders WHERE order_date = current_date;
DROP VIEW session.recent_orders; -- drops the temporary view
DROP VIEW default.recent_orders; -- drops the persistent view
```
