Dynamic generation of optimizer hints |
摘要 |
A fine-grained access control mechanism uses policy functions that are associated with a database object (e.g. table and view). The policy functions are invoked, when, for example, a database server detects that a query is issued against the database object. The policy functions return optimizer hints, which are added to the query.
