# REVOKE <privileges>

The `REVOKE <privileges>` 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`.

## Synopsis

## Required privileges

The user revoking privileges must have the `GRANT` privilege on the target databases or tables.

## Parameters

Parameter | Description
--- | ---
`table_name` | The name of the table for which you want to revoke privileges. To revoke privileges for multiple tables, use a comma-separated list of table names. To revoke privileges for all tables, use `*`.
`database_name` | The name of the database for which you want to revoke privileges. To revoke privileges for multiple databases, use a comma-separated list of database names. Privileges revoked for databases will be revoked for any new tables created in the databases.

## Examples

### Revoke privileges on databases

    > SHOW GRANTS ON DATABASE db1, db2;

    | Database |    User    | Privileges |
    +----------+------------+------------+
    | db1      | betsyroach | CREATE     |
    | db1      | maxroach   | CREATE     |
    | db1      | root       | ALL        |
    | db2      | betsyroach | CREATE     |
    | db2      | maxroach   | CREATE     |
    | db2      | root       | ALL        |
    +----------+------------+------------+
    (6 rows)

    > REVOKE CREATE ON DATABASE db1, db2 FROM maxroach, betsyroach;

    > SHOW GRANTS ON DATABASE db1, db2;

    +----------+------+------------+
    | Database | User | Privileges |
    +----------+------+------------+
