Delete the current database, which is test by default, and you can use the DB command to view the current database name.

Example

The following example we deleted the database Runoob. First, look at all the databases:

> Show dbs

To execute the Delete command:

> db.dropdatabase ()
{"Dropped": "Runoob", "OK": 1}

Finally, we pass the show DBS command database for deletion success:
