# REVOKE {#revoke}
|
|
|
|
Revoca privilegios de usuarios o roles.
|
|
|
|
## Sintaxis {#revoke-syntax}
|
|
|
|
**Revocación de privilegios de usuarios**
|
|
|
|
``` sql
|
|
REVOKE [ON CLUSTER cluster_name] privilege[(column_name [,...])] [,...] ON {db.table|db.*|*.*|table|*} FROM {user | CURRENT_USER} [,...] | ALL | ALL EXCEPT {user | CURRENT_USER} [,...]
|
|
```
|
|
|
|
**Revocación de roles de usuarios**
|
|
|
|
``` sql
|
|
REVOKE [ON CLUSTER cluster_name] [ADMIN OPTION FOR] role [,...] FROM {user | role | CURRENT_USER} [,...] | ALL | ALL EXCEPT {user_name | role_name | CURRENT_USER} [,...]
|
|
```
|
|
|
|
## Descripci {#revoke-description}
|
|
|
|
Para revocar algún privilegio, puede usar un privilegio de alcance más amplio que planea revocar. Por ejemplo, si un usuario tiene `SELECT (x,y)` privilegio, administrador puede realizar `REVOKE SELECT(x,y) ...`, o `REVOKE SELECT * ...` o incluso `REVOKE ALL PRIVILEGES ...` consulta para revocar este privilegio.
|
|
|
|
### Revocaciones parciales {#partial-revokes-dscr}
|
|
|
|
Puede revocar una parte de un privilegio. Por ejemplo, si un usuario tiene `SELECT *.*` privilegio puede revocarle un privilegio para leer datos de alguna tabla o una base de datos.
|
|
|
|
## Ejemplos {#revoke-example}
|
|
|
|
Otorgue el `john` cuenta de usuario con un privilegio para seleccionar de todas las bases de datos `accounts` una:
|
|
|
|
``` sql
|
|
GRANT SELECT ON *.* TO john;
|
|
REVOKE SELECT ON accounts.* FROM john;
|
|
```
|
|
|
|
Otorgue el `mira` cuenta de usuario con un privilegio para seleccionar entre todas las columnas `accounts.staff` excepción de la tabla `wage` una.
|
|
|
|
``` sql
|
|
GRANT SELECT ON accounts.staff TO mira;
|
|
REVOKE SELECT(wage) ON accounts.staff FROM mira;
|
|
```
