object_type:
    TABLE
  | FUNCTION
  | PROCEDURE

Description

The REVOKE statement enables system administrators to revoke privileges (or roles - see section below) from MariaDB accounts. Each account is named using the same format as for the GRANT statement; for example, 'jeffrey'@'localhost'. If you specify only the user name part of the account name, a host name part of '%' is used. For details on the levels at which privileges exist, the allowablepriv_type and priv_level values, and the syntax for specifying users and passwords, see GRANT.

To use the first REVOKE syntax, you must have theGRANT OPTION privilege, and you must have the privileges that you are revoking.

To revoke all privileges, use the second syntax, which drops all global, database, table, column, and routine privileges for the named user or users:

REVOKE ALL PRIVILEGES, GRANT OPTION FROM user [, user] ...

To use this REVOKE syntax, you must have the global CREATE USER privilege or the UPDATE privilege for the mysql database. See GRANT.

Examples

REVOKE SUPER ON *.* FROM 'alexander'@'localhost';

Roles

Syntax

REVOKE role  [, role ...]
    FROM grantee [, grantee2 ... ]

REVOKE ADMIN OPTION FOR role FROM grantee [, grantee2]

Description

REVOKE is also used to remove a role from a user or another role that it's previously been assigned to. If a role has previously been set as a default role, REVOKE does not remove the record of the default role from the mysql.user table. If the role is subsequently granted again, it will again be the user's default. Use SET DEFAULT ROLE NONE to explicitly remove this.

Current

REVOKE role is also permitted in prepared statements.

< 10.1.13

Example

REVOKE journalist FROM hulda

Revoking Proxy

The REVOKE PROXY syntax removes the ability for one user to proxy as another.

REVOKE PROXY ON 'dba_user'@'localhost' FROM 'app_user'@'localhost';
