Class UpdateDeleteFilter

java.lang.Object
oracle.odi.dataservices.fwk.UpdateDeleteFilter

public class UpdateDeleteFilter

extends java.lang.Object

A data service parameter used to define filters when deleting or updating a datastore via a ManagedEntity. This class can be used as an input parameter for a data service method.

Filtering is managed in two ways:

• by using a reference ManagedEntity, for which certain fields are defined. The filter will reject all ManagedEntity objects for which at least one field value does not match the corresponding value defined in the reference ManagedEntity.
• by using an expression in SQL syntax that will be applied in a WHERE clause.

Operations on datastores such as UPDATE and DELETE can be applied to a subset of the datastore using such filters.
