# ALTER ROLE

`ALTER ROLE` changes a role's description in the current service group. It does not change the privileges in the role.

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

## Syntax

Syntax diagramBNF

 alter_role_command  

````
alter_role_command ::=
    'ALTER' 'ROLE' role_name 'SET' 'COMMENT' '=' '"' comment '"'

````

## Parameters

### `role_name`

The name of the role to be altered.

### `comment`

The new description of the role. The description must be a string literal.

## Examples

The example uses an existing role named `role1`.

````
ALTER ROLE role1 SET COMMENT = "This is new description for role1"

````

Use [SHOW ALL ROLES](https://dev-docs.nebula-graph.io/v5.3.2/database-gql-reference/data-admin/show/show-all-roles/) to check that `role1` has the new `comment`.
