Description

TDataSetField provides access to nested datasets.

TDataSetField represents a nested dataset field in a database. This nested dataset can result from an object relational database (such as the nested datasets in Oracle 8 databases) or from a provider that packages data for the master table of a master/detail relationship.

TDataSetField introduces a new property NestedDataSet for referencing nested datasets. It also introduces the Fields property for accessing the fields in the nested dataset. When assigning data to a dataset field, use the DataSetField property of a dataset component that is assigned as the value of the dataset field.
