您要查找的是不是：
- In order to cut down the enormous search space of parallel query optimization, PBASE/2 divides parallel query processing into two phases, sequential optimization and parallelization. 为了缩减并行查询优化庞大的搜索空间,PBASE/2将并行查询优化划分为顺序优化和并行化两个阶段。
- parallel query optimization 并行查询优化
- The Gather Streams operator is only used in parallel query plans. Gather Streams运算符仅用在并行查询计划中。
- Variables do not generate parallel query execution plans. 变量的查询不会生成并行查询执行计划。
- Yes, a full scan is a good candidate for parallel query. 是的,一个全遍历是实施并行查询的很好的备选对象。
- The query processor ran out of stack space during query optimization. 查询处理器在优化查询时堆栈空间不足。
- The query processor could not start the necessary thread resources for parallel query execution. 查询处理器未能为执行并行查询启动必要的线程资源。
- Note that sometimes parallel query plans are run in serial if there is a high concurrent load on the server. 请注意,如果服务器上的并发负荷很高,则并行查询计划有时会以串行方式运行。
- In a parallel query execution plan, the insert, update, and delete operators are executed serially. 在并行查询执行计划中,插入、更新和删除运算符是串行执行的。
- Parallel query and parallel DML work with bitmap indexes as with traditional indexes. 与普通索引一样，位图索引能与并行查询和并行DML一起工作。
- Describes statement processing, stored procedure execution, query plan caching and reuse, and parallel query processing. 介绍语句处理、存储过程执行、查询计划缓存和重用以及并行查询处理。
- ON Any missing statistics required by a query for optimization are automatically built during query optimization. 在查询优化期间,将自动生成优化查询需要但缺少的任何统计信息。
- Set the value to a number greater than 1 to restrict the maximum number of processors used by a single parallel query execution. 将该值设置为大于1的数来限制执行单个并行查询时所使用的最大处理器数。
- Finally, this discussion of query languages may leave you wondering about a related topic: query optimization. 最后,关于查询语言还有一个相关的主题:查询优化。
- Specifies that the join order indicated by the query syntax is preserved during query optimization. 指定在查询优化过程中保持由查询语法指示的联接顺序。
- The semantics information is important to the design of XML schema,query optimization and check of update abnormity. 通过该算法得到的XML函数依赖的语义信息对数据存储模式设计、查询优化和更新异常检查来说是十分重要的。
- The component that does this is called the query optimizer. 处理此过程的组件称为“查询优化器”。
- This makes sure that the plan guide is used by the query optimizer. 这将确保计划指南可由查询优化器使用。
- Query optimizers estimate only intermediate result sizes. 查询优化器只估计中间结果的大小。
- Histogram can also be used in spatio-temporal query optimization after some improvements. 通过特定的改进，直方图也可应用到时空查询优化中。
