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.
