getAlias
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][google.datastore.v1.Entity.properties] limitations.
string alias = 7 [(.google.api.field_behavior) = OPTIONAL];
- Returns:
- The alias.
-
getAliasBytes
com.google.protobuf.ByteString getAliasBytes()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][google.datastore.v1.Entity.properties] limitations.
string alias = 7 [(.google.api.field_behavior) = OPTIONAL];
- Returns:
- The bytes for alias.
