getAlias()

public 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	The alias.

getAliasBytes()

public 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 ( ... ); `
