Use SVV\$1TABLES to view tables in local and external catalogs.

SVV\$1TABLES is visible to all users by default. To control access to your database's metadata, enable metadata security for your provisioned cluster or serverless workgroup. Metadata security lets you separate view permissions for object metadata by users and roles. For more information, see [Metadata security](t_metadata_security.md).
