CBR-002 11.37 11.37 Function Destroy privileges. Let A be the current . For every specified, a set of privilege descriptors is iden- tified. A privilege descriptor is said to be identified if it belongs to the set of privilege descriptors that define, for any explicitly or implicitly in , that on O granted by A to . The ac- tion and the identified column of P are the same as the action and identified column of D, respectively.
P is a table privilege descriptor and D is a column privilege descriptor.
Neither P nor D are column privilege descriptors. The action and the identified table, domain, character set, collation, or translation of P are the same as the ac- tion and the identified table, domain, character set, collation, or translation of D, respectively. Let CTN be the of the column of the from which CV is derived. An independent node is one that has no incoming arcs. There exists a path to P from an independent node that includes no identified or modified privilege descriptors.
