Abstract
Provided is a method, system, and program for implementing a database trigger. Upon detecting a trigger event, a determination is made of at least one row in a base table affected by the trigger event. For each column in the base table of a data type that is referenced in a triggered action associated with the trigger event, a reference is generated referencing the data of the data type. The reference is inserted in a transition table column including data of the data type from the affected row in the base table referenced in the triggered action. The reference is used to access the data of the data type when performing the triggered action.
