Is the dataset using persistent fields or not.
Source position: db.pas line 1948
public property TDataSet.DefaultFields : Boolean |
DefaultFields is True if the fields were generated dynamically when the dataset was opened. If it is False then the field instances are persistent, i;e. they were created at design time with the fields editor. If DefaultFields is True, then for each item in the TDataset.FieldDefs property, a field instance is created. These fields instances are freed again when the dataset is closed.
If DefaultFields is False, then there may be less field instances than there are items in the FieldDefs property. This can be the case for instance when opening a DBF file at runtime which has more fields than the file used at design time.
