Attributes

distinct_on[RW]

The properties to make distinct. The query results will contain the first result for each distinct combination of values for the given properties (if empty, all results are returned). Corresponds to the JSON property `distinctOn` @return [Array<Google::Apis::DatastoreV1beta3::PropertyReference>]

end_cursor[RW]

An ending point for the query results. Query cursors are returned in query result batches and [can only be used to limit the same query](cloud. google.com/datastore/docs/concepts/queries#cursors_limits_and_offsets). Corresponds to the JSON property `endCursor` NOTE: Values are automatically base64 encoded/decoded in the client library. @return [String]

filter[RW]

A holder for any type of filter. Corresponds to the JSON property `filter` @return [Google::Apis::DatastoreV1beta3::Filter]

kind[RW]

The kinds to query (if empty, returns entities of all kinds). Currently at most 1 kind may be specified. Corresponds to the JSON property `kind` @return [Array<Google::Apis::DatastoreV1beta3::KindExpression>]

limit[RW]

The maximum number of results to return. Applies after all other constraints. Optional. Unspecified is interpreted as no limit. Must be >= 0 if specified. Corresponds to the JSON property `limit` @return [Fixnum]

offset[RW]

The number of results to skip. Applies before limit, but after all other constraints. Optional. Must be >= 0 if specified. Corresponds to the JSON property `offset` @return [Fixnum]

order[RW]

The order to apply to the query results (if empty, order is unspecified). Corresponds to the JSON property `order` @return [Array<Google::Apis::DatastoreV1beta3::PropertyOrder>]

projection[RW]

The projection to return. Defaults to returning all properties. Corresponds to the JSON property `projection` @return [Array<Google::Apis::DatastoreV1beta3::Projection>]

start_cursor[RW]

A starting point for the query results. Query cursors are returned in query result batches and [can only be used to continue the same query](cloud. google.com/datastore/docs/concepts/queries#cursors_limits_and_offsets).
