Overrides
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.
string alias = 7 [(.google.api.field_behavior) = OPTIONAL];
Returns |
