REVOKE FROM ROLE
Access to Dremio objects can be managed by revoking privileges from roles. A privilege is the right to perform a specific action on an object.
SyntaxREVOKE { objectPrivilege | ALL } ON { <object_type> <object_name> }
FROM ROLE <role_name>
REVOKE { objectPrivilege } ON ALL FOLDERS IN CATALOG { <object_name> }
FROM ROLE <role_name>
REVOKE { objectPrivilege } ON ALL DATASETS IN CATALOG { <object_name> }
FROM ROLE <role_name>
The DELETE, INSERT, TRUNCATE, and UPDATE privileges are supported only for Iceberg tables.
The CREATE TABLE and DROP privileges are supported only for sources that support mutability.

Parameters
<objectPrivilege> String
The privilege(s) to be revoked from the role. A comma-separated list of privileges can be specified. For more information, read Privileges.
<object_type> String
The name of the type of object for which the specified privilege is being revoked.
<object_name> String
The name of the object for which the privilege is being revoked. Object names need to be qualified with the path if they are nested.
For <object_type> ORG or PROJECT, the <object_name> is inferred and should be omitted from the statement.
AT { REF[ERENCE] | BRANCH | TAG | COMMIT } <refValue> String Optional
For tables and views in an Arctic catalog, reference to the specific branch, tag, or commit in the catalog where you want to run the SQL command. If you do not specify a reference value in the command for a table or view in an Arctic catalog, the command runs on the catalog's default branch
<role_name> String
The name of the role from which the privilege is being revoked.
