|See also: NominalID, TNominalIDStr, OrdinalOfNominalID, Nominal and Ordinal Data|
The method AddNominalID adds the nominal identifier MScaleID to the list of nominal identifiers of the column Col and returns its ordinal number if the call to AddNominalID was successful, otherwise a zero value is returned. AddNominalID triggers the OnChangeSetup event.
Please note that AddNominalID automatically sets the measurement scale type of the column Col to stNominal.
