摘要：有效的支持结构连接是实现数据库系统XML文件查询的关键。
Absrtact: efficient support for structural joins is the key to efficient implementations of XML queries on database system.
您还可以创建一个类来管理数据对象，这个对象包含您从JSON文件查询得到的所有信息。
You can also create a class to manage the data object, which will contain all the information that you retrieved from the JSON file.
我能够单元测试通过运行我的函数加载hbm映射文件查询，添加参数和执行查询。
I am able to unit test my mapping files by running my function that loads the HBM query, adds parameters and executes the query.
安装的lib目录中还有其他很多JAR文件，但是简单的文件查询用不到这些文件。
A lot of other JAR files are in the lib directory of your installation, but you don't need any of those for simple file querying.
每个应用程序页面每60ms从数据库执行10次配置文件查询，峰值每秒共80k次请求。
Each application page performed 10 profile lookups from the database at 60 ms each, for a peak total of 80k requests per second.
所以，在程序开始遍历这些文件的时候，假设为了确定目录的总大小，就必须逐一重新查询文件系统。
So when the program starts to loop through the files, perhaps to determine the directories overall size, it has to requery the file system one by one.
它支持在文件系统中创建和删除配置文件，并在这些文件内查询和设置单独的属性(用于存储状态信息)。
It supports the creation and deletion of configuration files on the file system and the querying and setting of individual properties within those files (for storing the state information).
在使用之前先测试XML文件中的SQL查询。
将清单7中的查询保存到文件中。
创建一个SQC文件来执行主查询。
通常，这涉及到统计输入、输出、查询、文件和接口的数量，然后为各自制定一个复杂性系数。
Typically, this involves counting the number of inputs, outputs, queries, files, and interfaces, then assigning a complexity coefficient to each of them.
还需要一个进行实际查询的XML文件。
在清单11中，通过创建保存查询的外部文件使查询参数化。
In Listing 11, parameterize your query by creating an external file that holds your query.
在默认源代码中使用类路径的地方，可以用查询类文件的其他路径或者其他访问类信息的方法替换。
You can substitute other paths for looking up class files, or other ways of accessing class information, in place of the default source that USES the classpath.
文件系统缓存仅对查询Q1(检索全部文档，无谓词运算)有较大影响。
File system caching has a significant impact only on query Q1 which retrieves all documents without any predicate evaluation.
SNAPSHOT _FILEW过程将系统快照数据编写到随后可以进行查询的文件中。
SNAPSHOT_FILEW Procedure Writes system snapshot data to a file that can be subsequently queried.
此外，还可以使用以下这种面向对象的查询语言将XML文件作为EMF对象进行查询：对象约束语言(ocl)。
In addition, it is possible to query the XML files as EMF objects using an object-oriented query language: object Constraint language (OCL).
通过查询字典文件确定元素的内容没有拼写错误。
The content of an element is correctly spelled, as determined by consulting a dictionary file.
有了这个FileReader对象之后，XQExpression对象将使用前面的绑定值在该文件中执行查询。
With this FileReader object, the XQExpression object then executes the query in the file, using the previously bound values.
与传统的Web应用程序框架不同，Xquery很容易在查询文件中构造业务逻辑。
Unlike a traditional Web application framework, XQuery can construct the business logic easily in a query file.
应用程序使用这些别名来构建访问DB 2、Oracle和文本文件的查询。
The application can use these nicknames to build a query to access DB2, Oracle, and text file data.
只要删除-example，则该文件将在查询服务启动时生效。
Simply remove the "-example" and the file will take effect upon startup of the query service.
改善的统计信息收集和查询解释文件。
还可以通过编辑搜索服务器的runtime - generic . properties文件改变查询统计数据计算方式。
You can also change how query statistics are calculated by editing the runtime-generic.properties file for the search server.
使用LocalEnvironment变量查询文件记录编号。
Using the LocalEnvironment variables to query the file record number.
setexplainon 指示IDS生成显示查询计划的文件。
set explain on directs IDS to generate a file that shows the query plan.
第2步—准备和绑定expcat . sqc文件，它会为主查询创建包。
Step 2 - Prepare and bind the expcat.sqc file, which will create the packages for the main query.
SPARQL查询运行的文件的名称。
如果不确定该编辑哪个php . ini文件，可以查询php本身。
If you are unsure which php.ini file to edit, you can query PHP itself. Create this three-line program and run it using the browser or the interactive interpreter.
为了得到端口的值，要查询文件taplist。
