Re: Dates and triggers.

[Nelson Smith <ncsmith@xxxxxxxx>]

All of our newer database files have triggers which (among other things)
record a timestamp in each record.  The only time we get date errors is
when the application program fails to initialize the field and writes
the record with the trigger turned OFF. As long as the trigger is turned
ON, no errors. 

This says to me that the trigger buffer does accept a blank in a date or
timestamp field and produces no error as long as the trigger does load
that field with a valid date before the record is actually written. As
to invalid data other than blanks, I'm not sure.
