Abstract
Provided are techniques for creating one or more fine-grained access control rules that are associated with a base table. A materialized query table is created from the base table without applying the one or more fine-grained access control rules associated with the base table when obtaining data from the base table. A fine-grained access control protection indicator is turned on for the materialized query table. In response to receiving a direct access request to the materialized query table in a query referencing the materialized query table, access is provided to the data in the materialized query table by applying one or more fine-grained access control rules associated directly with the materialized query table to the data in the materialized query table before returning the data.
