摘要: Embodiments of the invention provide a method of optimizing a query, including determining an execution plan for use in executing the query, based on a monetary cost of the energy needed to execute the query. A query optimization component may determine a plurality of execution plans for the query. The query optimization component may then select one of the plans to use in executing the query based on the monetary cost calculated for the plan.
