Characteristics of Null Values

Print this Topic Previous pageReturn to chapter overviewNext page

RaceMate MCL provides support for null values. This support simplifies the task of representing unknown data. Null values are:


Equal to the absence of any value.
Different than zero, the empty string (""), or blank.
Sorted ahead of other data.
Propagated in calculations and most functions.


A null value is displayed as .NULL. When you double-clicking on a cell of null value in a RaceMate view, RaceMate will display a box showing information, if available, about how the value is got.
