Methods

#distinct_on

def distinct_on() -> ::Array<::Google::Cloud::Datastore::V1::PropertyReference>
Returns
  • (::Array<::Google::Cloud::Datastore::V1::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).

    Requires:

    • If order is specified, the set of distinct on properties must appear before the non-distinct on properties in order.

#distinct_on=

def distinct_on=(value) -> ::Array<::Google::Cloud::Datastore::V1::PropertyReference>
Parameter
  • value (::Array<::Google::Cloud::Datastore::V1::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).

    Requires:

    • If order is specified, the set of distinct on properties must appear before the non-distinct on properties in order.
Returns
  • (::Array<::Google::Cloud::Datastore::V1::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).

    Requires:

    • If order is specified, the set of distinct on properties must appear before the non-distinct on properties in order.

#limit

def limit() -> ::Google::Protobuf::Int32Value
Returns
  • (::Google::Protobuf::Int32Value) — The maximum number of results to return. Applies after all other constraints. Optional. Unspecified is interpreted as no limit. Must be >= 0 if specified.

#offset

def offset() -> ::Integer
Returns
  • (::Integer) — The number of results to skip. Applies before limit, but after all other constraints. Optional. Must be >= 0 if specified.
