For example, if a user has the `SELECT (x,y)` privilege, administrator can execute `REVOKE SELECT(x,y) ...`, or `REVOKE SELECT * ...`, or even `REVOKE ALL PRIVILEGES ...` query to revoke this privilege. ### Partial Revokes You can revoke a part of a privilege. For example, if a user has the `SELECT *.*` privilege you can revoke from it a privilege to read data from some table or a database. ## Examples Grant the `john` user account with a privilege to select from all the databases, excepting the `accounts` one: ``` sql GRANT SELECT ON *.* TO john; REVOKE SELECT ON accounts.* FROM john; ``` Grant the `mira` user account with a privilege to select from all the columns of the `accounts.staff` table, excepting the `wage` one. ``` sql GRANT SELECT ON accounts.staff TO mira; REVOKE SELECT(wage) ON accounts.staff FROM mira; ``` [Original article](https://clickhouse.com/docs/en/operations/settings/settings/)
