Sorting is required when no index satisfies the requested ordering of fetched rows, or the optimizer determines that a sort is less expensive than an index scan.
如果没有索引满足所取的行的要求顺序，或者优化器断定排序的代价低于索引扫描，那么就需要进行排序。

Sorting and classifying are two basic kinds of knowledge and mining ordering rules is a novel thought. The algorithms for ordering rules is discussed deeply and improved in this paper.
排序和分类是人类的两种基本知识，一般文献中讨论的都是关于分类规则的挖掘，挖掘排序规则是一种新的思想，本文对挖掘排序规则的算法作了更为全面深入的探讨并加以改进。
