{{Feature|informative|
Before {{arma3}} v2.00, [[isNull]] did not work with the diary record type and [[diaryRecordNull]] did not exist.
In order to verify a null record, it is possible to create a variable and compare against it:
<sqf>
private _diaryRecordNull = objNull createDiaryRecord [];
private _createdRecord = player createDiaryRecord ["Diary", ["Title", "Description"]];
if (_createdRecord isEqualTo _diaryRecordNull) then { hint "Failed"; };
</sqf>

Description

Description:
