The Drop Database command definitely deletes a database. If a database is open and no database name is used, then the current database will be deleted. NOTE: Unless you've made backups there is no way to restore a deleted database.
For database opened using "local" protocol:
To remove a database hosted in a remote OrientDB Server you need the credential to do it at the target OrientDB server:
DROP DATABASE <database-name> <server-username> <server-userpassword>
Delete the current local database:
Delete the remote database "demo" hosted on localhost:
DROP DATABASE remote:localhost/demo root 5B1A917B20C78ECAA219E37CFDDA6598D4D62CE68DD82E5B05D4949758A66828
To create a new database use the Create Database command.
