摘要：
Access to a data element stored within a database object is controlled. A request is received from a user to perform an operation in relation to the database object, the operation including retrieval of information from the data element of the database object. Prior to retrieving information from the data element, a determination is made whether at least a portion of the information from the data element is subject to masking in accordance with an access policy. In response to determining that information from the data element is subject to masking, the request is modified to require that information from the data element be retrieved in a masked condition.
