I don't know about MSSQL, but InterBase and other engines do not
provide 'date-only' fields. InterBase fields must be used with a
TDateTimeField object because there *could* be a time value specified.
I think there is no solution other than using Paradox Timestamp fields
(which should also map to TDateTimeField) or creating the TField
object programmatically, taking into account the type of db the app is
actually using.
