Re: Accomodating non-valid dates in a date/time field

Tech-Archive recommends: Repair Windows Errors & Optimize Windows Performance

And possibly add a yes/no field that stores -1 if the date is missing. You
can then display whatever you want in forms and reports based on the yes/no
field.

The only way to do that is to store it as text, not a date, but that will
mean all sorts of conversion routines whenever you want to do something with
it. Personally, I'd leave it NULL.

Is there anyway to accomodate missing dates in a date field? For example,
I
want to enter 99/99/99 in a date field to signal that this date was not
provided on the paper form, when entering this data into the database
form.
But, if a field is set up as a date/time field, 99/99/99 is not a valid
date.
So, it's rejected.

I'm using 9 because the rest of my fields are coded and set up to use 9 to
indicate missing data and we'd like this coding to be consistent. I don't
want to leave the field blank if the date is missing because we want to
make
sure that there is an specific explanation for missing data, i.e. it
wasn't
that the handwriting was unreadable ("7") or that the individual doing
data
entry just forgot to enter it.

Any suggestions?
Thanks.
