The $UPDVAL function is used in conjunction with the ON FIELD CONSTRAINT CONFLICT unit. If $UPDVAL is invoked from an ON FCC unit following the detection of a field-level constraint conflict, it returns the field value which is causing the constraint violation. At all other times, $UPDVAL returns a null string. The $UPDVAL function takes no arguments.
