Revokes privileges from users or roles.
## Syntax {#revoke-syntax}
**Revoking privileges from users**
``` sql
REVOKE [ON CLUSTER cluster_name] privilege[(column_name [,...])] [,...] ON {db.table|db.*|*.*|table|*} FROM {user | CURRENT_USER} [,...] | ALL | ALL EXCEPT {user | CURRENT_USER} [,...]
```
**Revoking roles from users**
``` sql
REVOKE [ON CLUSTER cluster_name] [ADMIN OPTION FOR] role [,...] FROM {user | role | CURRENT_USER} [,...] | ALL | ALL EXCEPT {user_name | role_name | CURRENT_USER} [,...]
```
## Description {#revoke-description}
To revoke some privilege you can use a privilege of a wider scope than you plan to revoke. 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.
