DROP VIEW removes a view from your Materialize instances.
Materialize maintains views after you create them. If you no longer need the view, you can remove it.
Because views rely on receiving data from sources, you must drop all views that rely on a source before you can drop the source itself. You can achieve this easily using DROP SOURCE…CASCADE.
|IF EXISTS||Do not return an error if the named view does not exist.|

|RESTRICT||Do not drop this view if any other views depend on it. (Default)|
|CASCADE||Drop all views that depend on this view.|
