Drop collection in MongoDB 2016-05-18 02:53
Drop collection in MongoDB is easy. Use db.collection_name.drop() to drop the collection. All indexes in this collection will be also removed.
> show collections
system.indexes
test
users
> db.test.drop()
true
> show collections
system.indexes
users
One thing to note here is that this command will obtains a write lock on the database. Other operations will be blocked until drop command has completed.
