Abstract: In managing multiple versions of triggers, a database system creates a first version of a trigger to apply a first set of actions in response to a first triggering event. The database system also creates a second version of the trigger to apply a second set of actions to the database object in response to a second triggering event. Upon receiving a command to set the current version of the trigger to the second version, the database system sets the second version as the current version of the trigger. When the triggering event of the trigger occurs, the database system determines that the second version is the current version of the trigger, retrieves the second set of actions in the second version, and executes the second set of actions.

Abstract: In managing multiple versions of triggers, a database system creates a first version of a trigger to apply a first set of actions in response to a first triggering event, which includes: creating a first package for the first version of the trigger to include the first set of actions; linking the first package to the database object; and setting the first package as a current version of the trigger. The database system creates a second version of the trigger to apply a second set of actions to the database object in response to a second triggering event, which includes: creating a second package for the second version of the trigger to include the second set of actions; and linking the second package to the database object. In response to a command, the database system sets the current version of the trigger to the second package.

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.
