db. dropRole ( rolename, writeConcern )

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

The db.dropRole() method takes the following arguments:

Parameter	Type	Description
`rolename`	string	The name of the user-defined role to remove from the database.
`writeConcern`	document	Optional. The level of write concern for the removal operation. The `writeConcern` document takes the same fields as the `getLastError` command.

The db.dropRole() method wraps the dropRole command.

If run on a replica set, db.dropRole() is executed using majority write concern by default.

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
db.dropRole( "readPrices", { w: "majority" } )
