CREATE USER

On this page Carat arrow pointing down

The CREATE USER statement creates SQL users, which let you control privileges on your databases and tables.

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

Note:

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

Considerations

Required privileges

To create other users, the user must be a member of the admin role or have the CREATEROLE parameter set.

Synopsis

See CREATE ROLE: Synopsis.

Parameters

Parameter Description
name The name of the user to create.
WITH role_option Apply a role option to the role.

User names

  • Are case-insensitive.
  • Must start with a letter or underscore.
  • Must contain only letters, numbers, periods, or underscores.
  • Must be between 1 and 63 characters.
  • Cannot be none.
  • Cannot start with pg_ or crdb_internal. Object names with these prefixes are reserved for system catalogs.
  • User and role names share the same namespace and must be unique.

Role options

Role option Description
CANCELQUERY/NOCANCELQUERY Deprecated in v22.2: Use the CANCELQUERY system privilege. Allow or disallow a role to cancel queries and sessions of other roles. Without this role option, roles can only cancel their own queries and sessions. Even with the CANCELQUERY role option, non-admin roles 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 Deprecated in v23.1: Use the CHANGEFEED privilege. Allow or disallow a 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 a role to pause, resume, and cancel jobs. Non-admin roles cannot control jobs created by admin roles.

By default, the role option is set to NOCONTROLJOB for all non-admin roles.
CREATEDB/NOCREATEDB Allow or disallow a 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 a 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 roles.
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 a 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 Deprecated in v22.2: Use the NOSQLLOGIN system privilege. 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 Deprecated in v22.2: Use the VIEWACTIVITY system privilege. 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.
VIEWCLUSTERSETTING / NOVIEWCLUSTERSETTING Deprecated in v22.2: Use the VIEWCLUSTERSETTING system privilege. Allow or disallow a role to view the cluster settings with SHOW CLUSTER SETTING or to access the Cluster Settings page in the DB Console.

By default, the role option is set to NOVIEWCLUSTERSETTING for all non-admin roles.
VIEWACTIVITYREDACTED/NOVIEWACTIVITYREDACTED Deprecated in v22.2: Use the VIEWACTIVITYREDACTED system privilege. 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 will not have access to the usage of statements diagnostics bundle (which can contain PII information) in the DB Console, and will not be able to list queries containing constants for other users when using the listSessions endpoint through the Cluster API. 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.

User authentication

Secure clusters require users to authenticate their access to databases and tables. CockroachDB offers three methods for this:

  • Client certificate and key authentication, which is available to all users. To ensure the highest level of security, we recommend only using client certificate and key authentication.

  • Password authentication, which is available to users and roles who you've created passwords for. To create a user with a password, use the WITH PASSWORD clause of CREATE USER. To add a password to an existing user, use the ALTER USER statement.

    Users can use passwords to authenticate without supplying client certificates and keys; however, we recommend using certificate-based authentication whenever possible.

    Password creation is supported only in secure clusters.

  • GSSAPI authentication, which is available to Enterprise users.

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 USERS;

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 user

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

root@:26257/defaultdb> CREATE USER no_options;

root@:26257/defaultdb> SHOW USERS;

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

After creating users, you must:

Create a user with a password

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

root@:26257/defaultdb> SHOW USERS;

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

Prevent a user from using password authentication

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

icon/buttons/copy 
root@:26257/defaultdb> CREATE USER no_password WITH PASSWORD NULL;

root@:26257/defaultdb> SHOW USERS;

  username    |                options                | member_of
--------------+---------------------------------------+------------
admin         |                                       | {}
no_options    |                                       | {}
no_password   |                                       | {}
root          |                                       | {admin}
