Declaration

TDADetailOption = (dtCascadeOpenClose, dtCascadeApplyUpdates, dtAutoFetch, dtCascadeDelete, dtCascadeUpdate,
                   dtDisableLogOfCascadeDeletes, dtDisableLogOfCascadeUpdates, dtIncludeInAllInOneFetch)

Values

Value	Description
dtCascadeOpenClose	Automatically open or close the detail table when the master table is opened or closed.
dtCascadeApplyUpdates	Automatically apply detail changes to the server when changes are applied on the master.
dtAutoFetch	Automatically fetch new data for this detail table, when the master record has changed.
dtCascadeDelete	Automatically delete detail records when the master record is deleted.
dtCascadeUpdate	Automatically update detail records, if one of the master fields has changed in the master, to keep the relationship intact.
dtDisableLogOfCascadeDeletes	Do not log cascaded detail deletes. Enable this option if the back-end database is configured to automatically cascade deletes on its own and the detail deletes do not have to be applied back to the database, individually.
dtDisableLogOfCascadeUpdates	Do not log cascaded detail updates. Enable this option if the back-end database is configured to automatically cascade updates on its own and the detail updates (if referring only to detail fields) do not have to be applied back to the database, individually.
dtIncludeInAllInOneFetch	Automatically download data for this detail table, when filling the master.
