Methods

getAlias()

public abstract String getAlias()

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:

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

becomes:

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 ( ... ); `

Requires:

  • Must be unique across all aggregation aliases.
  • Conform to entity property name limitations.

Returns
Type Description
String
