MessageOrBuilderMethods
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.
