REVOKE

On this page

Warning:

As of November 24, 2023, CockroachDB v22.1 is no longer supported. For more details, refer to the Release Support Policy.

The REVOKE statement revokes privileges from users and/or roles. For the list of privileges that can be granted to and revoked from users and roles, see GRANT.

You can use REVOKE to directly revoke privileges from a role or user, or you can revoke membership to an existing role, which effectively revokes that role's privileges.

Note:

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

Syntax

Parameters

Parameter	Description
`ALL` `ALL PRIVILEGES`	Revoke all privileges.
`targets`	A comma-separated list of database or table names, preceded by the object type (e.g., `DATABASE mydatabase`). Note: To revoke privileges on all tables in a database or schema, you can use `REVOKE ... ON TABLE *`. For an example, see Revoke privileges on all tables in a database or schema.
`name_list`	A comma-separated list of users and roles.
`target_types`	A comma-separated list of user-defined types.
`schema_name_list`	A comma-separated list of schemas.
`ALL TABLES IN SCHEMA`	Revoke privileges on all tables in a schema or list of schemas.
`privilege_list`	A comma-separated list of privileges to revoke.
`WITH ADMIN OPTION`	Designate the user as a role admin. Role admins can grant or revoke membership for the specified role.

Supported privileges

The following privileges can be revoked:

Privilege	Levels
`ALL`	Database, Schema, Table, Type
`CREATE`	Database, Schema, Table
`DROP`	Database, Table
`GRANT`	Database, Schema, Table, Type
`CONNECT`	Database
`SELECT`	Table
`INSERT`	Table
`DELETE`	Table
`UPDATE`	Table
`USAGE`	Schema, Type
`ZONECONFIG`	Database, Table

Required privileges

To revoke privileges, user revoking privileges must have the GRANT privilege on the target database, schema, table, or user-defined type. In addition to the GRANT privilege, the user revoking privileges must have the privilege being revoked on the target object. For example, a user revoking the SELECT privilege on a table to another user must have the GRANT and SELECT privileges on that table.
To revoke role membership, the user revoking role membership must be a role admin (i.e., members with the WITH ADMIN OPTION) or a member of the admin role. To remove membership to the admin role, the user must have WITH ADMIN OPTION on the admin role.

Considerations

The root user cannot be revoked from the admin role.

Examples

Setup

The following examples use MovR, a fictional vehicle-sharing application, to demonstrate CockroachDB SQL statements. For more information about the MovR example application and dataset, see MovR: A Global Vehicle-sharing App.

To follow along, run cockroach demo to start a temporary, in-memory cluster with the movr dataset preloaded:

$ cockroach demo
