 Oracle Data Access Components Overview

TVirtualTable component is TDataSet descendant. It represents an in-memory data storage that does not have linked data files. To add fields to virtual table call AddField method. Immediately after creating virtual table it will be empty. You then define new fields or load existing table files so that virtual table object becomes initialized and ready to be opened.

When you close virtual table it will discard its record set. To keep data you entered at design-time for later use you may wish to include voStored option in Options property. At run-time you need to call SaveToFile method explicitly to store modifications to the file that later may be retrieved back into the virtual table by calling LoadFromFile method.
