Therefore reducing the number of total connections per HTTP request by reusing a connection for more than one query improves processor, disk, and network performance. 因此,如果减少每个HTTP请求的总连接数,将一个连接用于多个查询,则可以提高处理器、磁盘和网络性能。
The query processor of XGrind can handle only exact-match and prefix-match queries on compressed values and partial-match and range queries on decompressed values. XGrind的查询处理器只能处理压缩值的精确匹配和前缀匹配查询,还可以处理对解压值的部分匹配和范围查询。
The Query Results XML format is a separate specification that defines an XML structure for data returned by a SPARQL query processor ( see Resources). QueryResultsXMLFormat是一个单独的规范,用于定义SPARQL查询处理程序返回数据的XML结构(参见参考资料)。

The query processor could not start the necessary thread resources for parallel query execution. 查询处理器未能为并行查询的执行启动必要的线程资源。
Internal Query Processor Error: The query processor encountered an unexpected work table error during execution. 内部查询处理器错误:查询处理器在执行过程中遇到意外的工作表错误。
Internal Query Processor Error: The plan selected for execution does not support the invoked given execution routine. 内部查询处理器错误:为执行选择的计划不支持唤醒调用的给定执行例程。
Since relational query processing is unsuitable for real-time databases, a real-time database system should have its own query processor. 由于现有的关系查询处理不能适合于实时数据库,因此实时数据库系统必须具有自己的查询处理器。
SAILII includes five parts: establishment of user's request for connection, query analysis processor, management of memory buffer and disk, and transaction processing. 该系统分为:用户请求连接建立、查询分析处理器、内存缓冲区管理、磁盘管理和事务处理五部分。
DQP: A Distributed Query Processor on Grid DQP:网格上的一种分布式查询处理器
This paper designed and realized a distributed database system of the urban electromagnetic environment and the distributed query processor in the system. 本文设计和实现了一个分布式的城市电磁环境数据库系统以及系统中的分布式查询处理模块。
Part-time Job The data must becleaned after the query processor integrating them. 查询处理器汇集这些数据以后需要进行数据清理工作。
The spreadsheet engine takes the queries with SPREADSHEET clause as inputs. Then a query is divided into two parts: the first part is the standard SQL query, which is sent to the query processor of OLAP server; 表格计算引擎以带有SPREADSHEET子句的查询作为输入,查询被分解为两个部分:标准的SQL查询部分交给OLAP服务器的查询处理器完成;
The query processor in this paper offsets the shortages of distributed query and optimization function in SQL Server 2000, it can be used in the distributed database systems which have the similar network structure with the urban electromagnetic environment inspect system. 本文实现的查询处理器弥补了SqlServer2000中分布式查询和优化功能的不足,它适用于与城市电磁环境监测系统具有相似网络结构的分布式数据库系统。

The most important character of the parallel processing method of spatial join query is that the distribution of task is based on plane sweeping algorithm, which avoids the cost of communication between processor in the join processing. 空间连接查询的并行处理方法最重要的特征是任务分配根据多路平面扫描顺序,避免了连接处理过程中处理器之间的通信花费。
After subquery returns results, query processor caches the results of the local subquery by block mechanism, eventually merge different subquery results through the join algorithm and return query results to the user. 在子查询完成返回结果后,查询处理器采用分块机制对局部子查询结果进行缓存,最终通过连接算法将不同子查询结果进行合并,并将合并后的结果返回给查询用户。
An algorithm for global decomposed querying based on the public model in the query processor has been proposed. 设计实现了查询处理器中基于公共模型的XQuery全局查询分解处理算法。
