The %command.name% command drops the default connections database:
php %command.full_name%
The --force parameter has to be used to actually drop the database.
You can also optionally specify the name of a connection to drop the database for:
php %command.full_name% --connection=default
Be careful: All data in a given database will be lost when executing this command.
