Remarks

• priv_level - privilege level

• priv_type - privilege type

• user_or_role: One or more user attributes or a role attribute. The @'host_name' part is optional. If a hostname is not specified, @'%' will be appended to the user string. For example, 'demo-user' is equivalent to 'demo-user'@'%'.The '%' wildcard matches any hostname. user and host_name need not be quoted if they are legal as unquoted identifiers. Quotes must be used if a host_name string contains wildcard characters (such as %), or a user string contains special characters (such as space or -) or is a restricted keyword.

• This command can be run on any SingleStore node.

• This command causes implicit commits. Refer to COMMIT for more information.

• GRANT OPTION must be revoked separately from any other privileges.

• The REVOKE command holds a global lock on the cluster until the processing of the command is completed. See Cluster Level Locks for more info.

• A user is granted the USAGE privilege by default. This privilege cannot be removed by using REVOKE [ALL]. The USAGEprivilege is automatically removed when the user is dropped.

• Refer to the Permission Matrix for the required permissions.
