Synopsis

CREATE USER username
[ WITH ( user_parameter = value [, ...]) ] |
[ [ WITH ] user_parameter [value] [ ... ] ]

Description

CREATE USER is a management statement to create a new database user in the CrateDB cluster. The newly created user does not have any special privileges, and those must be assigned afterwards, for details see the privileges documentation. The created user can be used to authenticate against CrateDB, see Host-Based Authentication (HBA).

The statement allows to specify a password for this account. This is not necessary if password authentication is disabled.

Note

USER is essentially the same as ROLE with the difference that a USER can login to the database and can also be assigned a password, but cannot be granted to another USER or ROLE. On the contrary, a ROLE cannot login to the database, and therefore cannot be assigned a password, but it can be granted to another USER or ROLE.

For usages of the CREATE USER statement see Users and roles management.

Parameters

username:

The unique name of the database user.

The name follows the principles of a SQL identifier (see Key words and identifiers).

Clauses

WITH

The following user_parameter are supported to define a new user account:

password:

The password as cleartext entered as string literal. e.g.:

CREATE USER john WITH (password='foo')

CREATE USER john WITH password='foo'

CREATE USER john WITH password 'foo'

CREATE USER john password 'foo'

jwt:

JWT properties map (‘iss’, ‘username’ and ‘aud’) entered as string literal. e.g.:

CREATE USER john WITH (jwt = {"iss" = 'https://example.com', "username" = 'test@example.com', "aud" = 'test_aud'})

iss is a JWK endpoint, containing public keys. Required field.

username is a user name in a third party app. Required field.

aud is a recipient that the JWT is intended for. Optional field. If not provided, the cluster id is used (default).

Combination of iss and username must be unique.
