Deletes a user-defined role from the database on which you run the command.


In mongosh, this command can also be run through the db.dropRole() helper method.

Helper methods are convenient for mongosh users, but they may not return the same level of information as database commands. In cases where the convenience is not needed or the additional return fields are required, use the database command.

The dropRole command uses the following syntax:

dropRole: "<role>",
writeConcern: { <write concern> },
comment: <any>

The dropRole command has the following fields:

The name of the user-defined role to remove from the database.

Optional. The level of write concern for the operation. See Write Concern Specification.


Optional. A user-provided comment to attach to this command. Once set, this comment appears alongside records of this command in the following locations:

A comment can be any valid BSON type (string, integer, object, array, etc).

When a role is dropped on a mongod, previously authenticated users remain logged in to the database but immediately lose the role's privileges.

When a role is dropped on a mongos, previously authenticated users remain logged in to the database but lose the role's privileges when the cache refreshes. The cache refreshes automatically after the time specified with the userCacheInvalidationIntervalSecs parameter or manually when you run the invalidateUserCache command.

You must have the dropRole action on a database to drop a role from that database.

The following operations remove the readPrices role from the products database:

use products
dropRole: "readPrices",
writeConcern: { w: "majority" }
