The DROP ROLE statement removes one or more SQL roles. You can use the keywords ROLE and USER interchangeably. DROP USER is an alias for DROP ROLE.
Note:
The DROP ROLE statement performs a schema change. For more information about how online schema changes work in CockroachDB, see Online Schema Changes.
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.
