Properties

Alias

public string Alias { get; set; }

Optional. Optional name of the property to store the result of the aggregation.

If not provided, Datastore will pick a default name following the format property_<incremental_id++>. For example:

  COUNT_UP_TO(2),
  COUNT_UP_TO(3) AS count_up_to_3,
  COUNT(*)
OVER (
  ...
);

AGGREGATE
  COUNT_UP_TO(1) AS count_up_to_1,
  COUNT_UP_TO(2) AS property_1,
  COUNT_UP_TO(3) AS count_up_to_3,
  COUNT(*) AS property_2
OVER (
  ...
);
