CREATE ROLE

On this page Carat arrow pointing down

The CREATE ROLE statement creates SQL roles, which are groups containing any number of roles and users as members. You can assign privileges to roles, and all members of the role (regardless of whether if they are direct or indirect members) will inherit the role's privileges.

Note:

The CREATE ROLE statement performs a schema change. For more information about how online schema changes work in CockroachDB, see Online Schema Changes.

Note:

The keywords ROLE and USER can be used interchangeably in SQL statements for enhanced PostgreSQL compatibility.

CREATE USER is equivalent to the statement CREATE ROLE, with one exception: CREATE ROLE sets the NOLOGIN option by default, preventing the new role from being used to log in to the database. You can use CREATE ROLE and specify the LOGIN option to achieve the same result as CREATE USER.

Considerations

  • Role names:
    • Are case-insensitive
    • Must start with either a letter or underscore
    • Must contain only letters, numbers, periods, or underscores
    • Must be between 1 and 63 characters.
    • New in v21.2: Cannot be none.
    • New in v21.2: Cannot start with pg_ or crdb_internal. Object names with these prefixes are reserved for system catalogs.
  • After creating roles, you must grant them privileges to databases and tables.
  • Roles and users can be members of roles.
  • Roles and users share the same namespace and must be unique.
  • All privileges of a role are inherited by all of its members.
  • Role options of a role are not inherited by any of its members.
  • There is no limit to the number of members in a role.
  • Membership loops are not allowed (direct: A is a member of B is a member of A or indirect: A is a member of B is a member of C ... is a member of A).

Required privileges

Unless a role is a member of the admin role, additional privileges are required to manage other roles.

  • To create other roles, a role must have the CREATEROLE role option.
  • To add the LOGIN capability for other roles so that they may log in as users, a role must also have the CREATELOGIN role option.
  • To be able to grant or revoke membership to a role for additional roles, a member of the role must be set as a role admin for that role.

Synopsis

CREATE ROLE USER IF NOT EXISTS name opt_with role_options

Parameters

Parameter Description
name The name of the role to create. Role names are case-insensitive; must start with either a letter or underscore; must contain only letters, numbers, periods, or underscores; and must be between 1 and 63 characters.

Note that roles and users share the same namespace and must be unique.
WITH role_option Apply a role option to the role.

Role options

Role option Description
CANCELQUERY/NOCANCELQUERY Allow or disallow the role to cancel queries and sessions of other roles. Without this role option, roles can only cancel their own queries and sessions. Even with this role option, non-admins cannot cancel admin queries or sessions. This option should usually be combined with VIEWACTIVITY so that the role can view other roles' query and session information.

By default, the role option is set to NOCANCELQUERY for all non-admin roles.
CONTROLCHANGEFEED/NOCONTROLCHANGEFEED Allow or disallow the role to run CREATE CHANGEFEED on tables they have SELECT privileges on.

By default, the role option is set to NOCONTROLCHANGEFEED for all non-admin roles.
CONTROLJOB/NOCONTROLJOB Allow or disallow the role to pause, resume, and cancel jobs. Non-admin roles cannot control jobs created by admins.

By default, the role option is set to NOCONTROLJOB for all non-admin roles.
CREATEDB/NOCREATEDB Allow or disallow the role to create or rename a database. The role is assigned as the owner of the database.

By default, the role option is set to NOCREATEDB for all non-admin roles.
CREATELOGIN/NOCREATELOGIN Allow or disallow the role to manage authentication using the WITH PASSWORD, VALID UNTIL, and LOGIN/NOLOGIN role options.

By default, the role option is set to NOCREATELOGIN for all non-admin roles.
CREATEROLE/NOCREATEROLE Allow or disallow the new role to create, alter, and drop other non-admin roles.

By default, the role option is set to NOCREATEROLE for all non-admin users.
LOGIN/NOLOGIN Allow or disallow a role to log in with one of the client authentication methods. Setting the role option to NOLOGIN prevents the role from logging in using any authentication method.
MODIFYCLUSTERSETTING/NOMODIFYCLUSTERSETTING Allow or disallow the role to modify the cluster settings with the sql.defaults prefix.

By default, the role option is set to NOMODIFYCLUSTERSETTING for all non-admin roles.
PASSWORD password/PASSWORD NULL The credential the role uses to authenticate their access to a secure cluster. A password should be entered as a string literal. For compatibility with PostgreSQL, a password can also be entered as an identifier.

To prevent a role from using password authentication and to mandate certificate-based client authentication, set the password as NULL.
SQLLOGIN/NOSQLLOGIN Allow or disallow a role to log in using the SQL CLI with one of the client authentication methods. The role option to NOSQLLOGIN prevents the role from logging in using the SQL CLI with any authentication method while retaining the ability to log in to DB Console. It is possible to have both NOSQLLOGIN and LOGIN set for a role and NOSQLLOGIN takes precedence on restrictions.

Without any role options all login behavior is permitted.
VALID UNTIL The date and time (in the timestamp format) after which the password is not valid.
VIEWACTIVITY/NOVIEWACTIVITY Allow or disallow a role to see other roles' queries and sessions using SHOW STATEMENTS, SHOW SESSIONS, and the Statements and Transactions pages in the DB Console. VIEWACTIVITY also permits visibility of node hostnames and IP addresses in the DB Console. With NOVIEWACTIVITY, the SHOW commands show only the role's own data, and DB Console pages redact node hostnames and IP addresses.

By default, the role option is set to NOVIEWACTIVITY for all non-admin roles.
VIEWACTIVITYREDACTED/NOVIEWACTIVITYREDACTED Allow or disallow a role to see other roles' queries and sessions using SHOW STATEMENTS, SHOW SESSIONS, and the Statements and Transactions pages in the DB Console. With VIEWACTIVITYREDACTED, a user won't have access to the usage of statements diagnostics bundle, which can contain PII information, in the DB Console. It is possible to have both VIEWACTIVITY and VIEWACTIVITYREDACTED, and VIEWACTIVITYREDACTED takes precedence on restrictions. If the user has VIEWACTIVITY but doesn't have VIEWACTIVITYREDACTED, they will be able to see DB Console pages and have access to the statements diagnostics bundle.

By default, the role option is set to NOVIEWACTIVITYREDACTED for all non-admin roles.

Examples

To run the following examples, start a secure single-node cluster and use the built-in SQL shell:

$ cockroach sql --certs-dir=certs

> SHOW ROLES;

username | options | member_of
---------+---------+------------
admin    |         | {}
root     |         | {admin}
(2 rows)
Note:

The following statements are run by the root user that is a member of the admin role and has ALL privileges.

Create a role

Role names are case-insensitive; must start with a letter, number, or underscore; must contain only letters, numbers, periods, or underscores; and must be between 1 and 63 characters.

root@:26257/defaultdb> CREATE ROLE no_options;

root@:26257/defaultdb> SHOW ROLES;

 username  | options | member_of
 ----------+---------+------------
admin      |         | {}
no_options | NOLOGIN | {}
root       |         | {admin}
(3 rows)

After creating roles, you must grant them privileges to databases.

Create a role that can log in to the database

root@:26257/defaultdb> CREATE ROLE can_login WITH LOGIN PASSWORD '$tr0nGpassW0rD' VALID UNTIL '2021-10-10';

root@:26257/defaultdb> SHOW ROLES;

 username  |                options                | member_of
-----------+---------------------------------------+------------
admin      |                                       | {}
can_login  | VALID UNTIL=2021-10-10 00:00:00+00:00 | {}
no_options | NOLOGIN                               | {}
root       |                                       | {admin}
(4 rows)

Prevent a role from using password authentication

The following statement prevents the role from using password authentication and mandates certificate-based client authentication:

icon/buttons/copy 
> CREATE ROLE no_password WITH PASSWORD NULL;

root@:26257/defaultdb> SHOW ROLES;

 username  |                options                | member_of
-----------+---------------------------------------+------------
admin      |                                       | {}
can_login  | VALID UNTIL=2021-10-10 00:00:00+00:00 | {}
no_options | NOLOGIN                               | {}
no_password| NOLOGIN                               | {}
root       |                                       | {admin}
(5 rows)

Create a role that can create other roles and manage authentication methods for the new roles

The following example allows the role to create other users and manage authentication methods for them:

root@:26257/defaultdb> CREATE ROLE can_create_role WITH CREATEROLE CREATELOGIN;

root@:26257/defaultdb> SHOW ROLES;

   username     |                options                | member_of
----------------+---------------------------------------+------------
admin           |                                       | {}
can_create_role | CREATELOGIN, CREATEROLE, NOLOGIN      | {}
can_login       | VALID UNTIL=2021-10-10 00:00:00+00:00 | {}
no_options      | NOLOGIN                               | {}
no_password     | NOLOGIN                               | {}
root            |                                       | {admin}
(6 rows)

Create a role that can create and rename databases

The following example allows the role to create or rename databases:
