Abstract

Techniques are provided for updating data that logically resides in one or more nested collections in a nested collection column of a view. According to one technique, a Data Manipulation Language (DML) statement that operates on individual elements within the one or more nested collections is detected. Instead of executing the DML statement, trigger code is executed once for each individual element, within the one or more nested collections, that is targeted by the DML statement. In addition, the trigger code may include one or more references to parent values. For each nested collection selected by the DML statement, the following steps are performed when the trigger code includes references to parent values: determining the row, within the view, in which the nested collection resides and, prior to executing the trigger code for the nested collection, binding the one or more references to one or more corresponding values that logically reside in the row.
