REVOKE

description

REVOKE command is used to take back specified permissions of specified users or roles.

REVOKE privilege_list ON db_name[.tbl_name] FROM user_identity [ROLE role_name]

REVOKE privilege_list ON RESOURCE resource_name FROM user_identity [ROLE role_name]

user_identity:

Here, the syntax of user_identity is the same as that of CREATE USER and must be the user_identity previously created through CREATE USER. The host in user_identity could be a domain name. If it is, there may be a short one-minute delay before the revocation comes into effect.

The permission of specified ROLE can also be revoked with the precondition that the executed role must already exist.

example

  1. Revoke permission to database testDb from user jack

    
    REVOKE SELECT_PRIV ON db1.* FROM 'jack'@'192.%';
  2. Revoke usage permission to spark_resource from user jack

    REVOKE USAGE_PRIV ON RESOURCE 'spark_resource' FROM 'jack'@'192.%';
