How to clear a MongoDB database?
To clear, use dropDatabase. Following is the syntax −
use yourDatabaseName; db.dropDatabase();
To clear a MongoDB database, first show all the databases −
> show dbs
This will produce the following output −
MyDB 0.000GB admin 0.000GB config 0.000GB local 0.000GB onlinecustomertracker 0.000GB test 0.006GB
Now, let us delete the database onlinecustomertracker −
> use onlinecustomertracker
switched to db onlinecustomertracker
> db.dropDatabase();
{ "dropped" : "onlinecustomertracker", "ok" : 1 }Following is the query to show all databases after deleting a database above −
> show dbs
This will produce the following output −
