例如，某些. net framework方法和属性使用索引指定字符串中的某个字符或数组或集合中的某个元素。 - The logic used by the sql server query optimizer to decide when to use an indexed view is similar to the logic used to decide when to use an index on a table
Sql server查询优化器用于决定何时使用索引视图的逻辑与用于决定何时对表使用索引的逻辑相似。 - When the query optimizer uses an index , it searches the index key columns , finds the storage location of the rows needed by the query and extracts the matching rows from that location
查询优化器使用索引时，搜索索引键列，查找到查询所需行的存储位置，然后从该位置提取匹配行。 - However , for the optimizer to consider indexed views for matching or use an indexed view that is referenced with the noexpand hint , the following set options must be set to on
但是，为了使优化器考虑使用索引视图进行匹配或在引用索引视图时使用noexpand提示，必须将以下set选项设置为on ：
