Description¶

TGUIDField is the class used when a dataset must manage native variant-typed data. (TField.DataType equals ftGUID). It initializes some of the properties of the TField class and overrides some of its methods to be able to work with variant data. It also adds a method to retrieve the field value as a native TGUID type.

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