BigQuery Drop Schema

Permanently deletes a dataset and its contents

Drop dataset example

DROP SCHEMA mydataset

or

DROP SCHEMA IF EXISTS mydataset CASCADE

Explanation

IF EXISTS: If no dataset exists with that name, the statement has no effect.
dataset_name: The name of the dataset to delete.
CASCADE: Deletes the dataset and all resources within the dataset, such as tables, views, and functions. You must have permission to delete the resources, or else the statement returns an error
RESTRICT: Deletes the dataset only if it's empty. Otherwise, returns an error. If you don't specify either CASCADE or RESTRICT, then the default behavior is RESTRICT

Syntax reference

DROP SCHEMA [IF EXISTS]
[project_name.]dataset_name
[ CASCADE | RESTRICT ]
