# DROP ROLE

`DROP ROLE` deletes one or more roles from the current service group.

## Prerequisites

First [connect to the Graph service](https://dev-docs.nebula-graph.io/v5.3.2/get-started/first-query/#connect). Run the command in a GQL client.

To drop a role, you must own the role or have `ADMIN` in the current service group.

Warning

Dropping a role revokes it from every user and deletes the privileges stored in that role. It does not delete privileges granted directly to users or through other roles.

## Syntax

Syntax diagramBNF

 drop_role_command  

````
drop_role_command ::=
    'DROP' 'ROLE' ('IF EXISTS')? role_name (',' role_name)*

````

## Parameters

### `IF EXISTS`

Skip missing roles and delete the other specified roles. Without this clause, any missing role causes an error.

### `role_name`

The name of the role to be dropped.

## Examples

The example uses an existing role named `role1`.

````
DROP ROLE role1

````

Check [SHOW ALL ROLES](https://dev-docs.nebula-graph.io/v5.3.2/database-gql-reference/data-admin/show/show-all-roles/). The result should no longer include `role1`.
