TDATableFieldCollectionItem

Overview

TDATableFieldCollectionItem is a very simple base class used by the TDASimpleQueryBuilder. It represents certain data table fields inside the field collection.

It is used to generate a proper SQL statement for requesting data from a given data table in the database.

DataAbstract uses it behind the scene. In most cases you will not need to deal with this class directly, unless you want to override the TDAQueryBuilder class for custom purposes.
