That depends on what it is you want to do.
If the intent is to elimate all of the rows where there is an empty date (not what you originally asked for), then you might use the following in the record selection formula:
{table.date} <> CDate(1988,12,30)
If you want to show thee data for those rows, but don't want the oddball dates that are being returned by the database, create a formula to use as the date in lieu of the date field containing one of the above formulas.
