Dates with unknown date parts

If a date field allows unknown (UNK) values for a complete date, the InForm application stores the following date values:

• For a complete date:
  • A date/time column.
  • A date string column.
  • A month column.
  • A day column.
  • A year column.
• If there is at least one unknown value, the InForm application stores the date values in a date string column only.
