Documentation

Definition

Property "Null Value" defines how an empty entry is to be handled by the data container entry handler.

If "Null Value" is set, an empty entry is interpreted (as an undefined value whose comparison with a special value is always undefined) as such, and not as a type-related initial value.

If "Null Value" is not set, an empty entry is interpreted as a type-related initial value.

Use

Dependencies

The property is of significance for non-character type attributes.

Example

If "Null Value" is not set, an empty entry for an attribute of type TIMS (time field) is interpreted as time 00:00:00. The empty entry is therefore actually interpreted as an empty value.
