Description
Creates an instance of TAggregateField.
Call Create to create and initialize an instance of TAggregateField at runtime.
It is seldom necessary to call Create directly, because an aggregate field component is instantiated automatically when an aggregate field is added through the Fields editor of a client dataset.
Create initializes DataType to ftUnknown, FieldKind to fkAggregate, Precision to 15, and Visible to false.
