DROP EXTERNAL VIEW
Drops an external view from the database. Dropping an external view removes it from all SQL engines the view is associated with, such as Amazon Athena and Amazon EMR Spark. This command can't be reversed. For more information about Data Catalog views, see AWS Glue Data Catalog views.
Syntax
DROP EXTERNAL VIEW schema_name.view_name [ IF EXISTS ] {catalog_name.schema_name.view_name | awsdatacatalog.dbname.view_name | external_schema_name.view_name}
Parameters
- schema_name.view_name
-
The schema that’s attached to your AWS Glue database, followed by the name of the view.
- IF EXISTS
