Description

TSmallIntField is the class created when a dataset must manage 16-bit signed integer data, of datatype ftSmallInt. It exposes no new properties, but simply overrides some methods to manage 16-bit signed integer data.

It should never be necessary to create an instance of TSmallIntField manually, a field of this class will be instantiated automatically for each smallint field when a dataset is opened.
