<Key item>: Optional character string (with or without quotes)
Name of key item used to perform the statistical calculation. If this name is not specified, HStatNbRec will use the last item used by the last HFSQL management function (function starting with "H").
Remarks

  • In the HFSQL Classic data files, the statistical calculations can only be performed on key items.
