The DROP ROLE statement removes one or more SQL roles.
The DROP ROLE statement performs a schema change. For more information about how online schema changes work in CockroachDB, see Online Schema Changes.
DROP ROLE is no longer an Enterprise feature and is now freely available in the core version of CockroachDB. Also, since the keywords ROLE and USER can now be used interchangeably in SQL statements for enhanced PostgreSQL compatibility, DROP ROLE is now an alias for DROP USER.
Considerations
- The
adminrole cannot be dropped, androotmust always be a member ofadmin. - A role cannot be dropped if it has privileges. Use
REVOKEto remove privileges. - Roles that own objects (such as databases, tables, schemas, and types) cannot be dropped until the ownership is transferred to another role.
Required privileges
Non-admin roles cannot drop admin roles. To drop non-admin roles, the role must be a member of the admin role or have the CREATEROLE parameter set.
