Instance Attribute Details
#distinct_on ⇒ Array<Google::Apis::DatastoreV1beta3::PropertyReference>
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

# File 'generated/google/apis/datastore_v1beta3/classes.rb', line 1394 def distinct_on @distinct_on end |
#end_cursor ⇒ String
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.
Corresponds to the JSON property endCursor
NOTE: Values are automatically base64 encoded/decoded in the client library.

#limit ⇒ Fixnum
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

constraints. Optional. Must be >= 0 if specified.
Corresponds to the JSON property offset

can only be used to continue the same
query.
Corresponds to the JSON property startCursor
