db.dropDatabase()

Definition

db.dropDatabase()

Removes the current database, deleting the associated data files.

Behavior

The db.dropDatabase() wraps the dropDatabase command.

Warning

This command obtains a global write lock and will block other operations until it has completed.

Changed in version 2.6: This command does not delete the users associated with the current database. To drop the associated users, run the dropAllUsersFromDatabase command in the database you are deleting.

Warning

If you drop a database and create a new database with the same name, you must either restart all mongos instances, or use the flushRouterConfig command on all mongos instances before reading or writing to that database. This action ensures that the mongos instances refresh their metadata cache, including the location of the primary shard for the new database. Otherwise, the mongos may miss data on reads and may write data to a wrong shard.

Example

The following example in the mongo shell uses the use <database> operation to switch the current database to the temp database and then uses the db.dropDatabase() method to drops the temp database:

use temp
db.dropDatabase()
