Go Up to Database Dialog Boxes

Use this dialog box to add new persistent fields to a dataset and create data fields, calculated fields, and lookup fields. The dialog box is displayed when you right-click any of several dataset components, such as TClientDataSet, and choose Fields Editor.

Use the Fields Editor at design time to create persistent lists of the field components used by the datasets in your application. Persistent fields component lists are stored in your application, and do not change even if the structure of a database underlying a dataset is changed. All fields in a dataset are either persistent or dynamic.
