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:
<code><code>
AGGREGATE
COUNT_UP_TO(1) AS count_up_to_1,
COUNT_UP_TO(2),
COUNT_UP_TO(3) AS count_up_to_3,
COUNT_UP_TO(4)
OVER (
...
);
</code></code><code>
becomes:
</code><code><code>
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_UP_TO(4) AS property_2
OVER (
...
);
</code></code>
Requires:
- Must be unique across all aggregation aliases.
