62 Searching the Database Date Fields The display and entry format for stored search dates is controlled by the Short date style setting in the Regional Settings Properties dialog box of the Control Panel. Setting the Short date style to use a two-digit year may result in a year with a century that is not what the user expected. To avoid this possibility, select a Short date style setting that uses a four-digit year. Possible constraints for Production Form date fields are: Supported Options Constraint Rule Required Detail Exclude Case Insensitive NULL EXACT DATE A date Yes No Yes SINCE A date Yes No Yes BEFORE A date Yes No Yes BETWEEN Two dates Yes No Yes PREVIOUS _ DAYS An integer (1 - 31) No No No PREVIOUS _ MONTHS An integer (1 - 12) No No No IS NULL None No No No IS NOT NULL None No No No EXACT DATE Constraint Rule Use the EXACT DATE rule to match an exact date value. Because time may not be specified for the field but may be stored in the database, this constraint is turned into a BETWEEN constraint for the entered date between 00:00:00 and 23:59:59.
