    var
  NullMagnitudeRule: TNullCompareRule = (ncrError,ncrStrict,ncrLoose) = ncrLoose;

    Description

    NullEqualityRule is checked when the system needs to determine the ordering of variants with Null values (operations like opCmpGe, opCmpLe). Check TNullCompareRule for a list of allowed values. The default is ncrLoose.

    For determining equality (opCmpEq, opCmpNe) of Null values, see NullEqualityRule.
