drop whole database within a single command of restoring the dump of mongodb

问题

I am trying to restore the directory dump of mongodb.

i am doing

mongorestore --db mydb --drop path/to/mydb/dump

But both does not able to restore the state of my dump. Any new records are visible even after restoring the db.

But no error is shown on console.

I didn't see an answer and I had the same question today.

You can drop the database before with:

use <db>
db.dropDatabase()

Or you can only drop the collection with:

db.<collection>.drop()

The problem with your command could be that something misses, like the database which you authenticate against or the user or maybe another thing.

In my setup this works

mongorestore --username=<user> --db=<database> --authenticationDatabase=<database> --dir=<dumpdir> --drop

If your dump was zipped beforehand, you can add the --gzip flag in the end.

You can find all that in the documentation for dropping a database or in the documentation of dropping a whole database. But please be cautious with it.
