MongoDB Delete Database

Grammar

The syntax format for MongoDB database deletion is as follows:

Db.dropdatabase ()

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
local   0.078GB
runoob  0.078GB
test    0.078GB

Next we switch to database Runoob:

> Use Runoob
switched to DB Runoob

To execute the Delete command:

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

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

> Show dbs
local  0.078GB
test   0.078GB

Delete Collection

Collection Delete syntax format:

Db.collection.drop ()

The following instance removes the collection from the Runoob database site:

> Use Runoob
switched to DB Runoob
> Show Tables

> Db.site.drop ()
