The query is somewhat complex but provides a realistic example of how someone can return multiple portions of XML data (for example, multiple XML nodes) and restrict results based on an XML predicate.
此查询比较复杂，但是更加真实；它演示如何返回XML数据的多个部分（例如多个 XML节点）并根据 XML 谓词限制结果。
Additional scripts test the implemented mechanisms on the provided sample data and show an example of a distance-based query, complete with map images.
其他脚本在提供的数据示例上测试实现的机制，并给出一个基于距离的查询示例，而且与地图图像结合在一起。
Listing 1 gives an example of a SQL query based on a cube model and shows how the parts of the SQL statement map to the elements of the cube model.
清单1给出了一个基于多维数据集模型的SQL查询示例，并展示了sql语句的各个部分如何映射到多维数据集模型中的元素？
If I run a query based on Numbers, for example, SimpleDB will search based on characters, and not actual integer values.
如果我根据数字运行一个查询，例如，SimpleD b会基于字符执行搜索，而非真正的整数值。
DB2 Net search Extender provides a flexible query language to find relevant information based on complex retrieval operations involving Boolean combination, wildcard, and fuzzy search, for example.
DB 2NetSearchExtender提供了一种灵活的查询语言，可以根据复杂的获取操作(例如涉及布尔组合、通配符和模糊搜索)寻找相关信息。
For example, a view based on a very complex query that returns only five rows (for example, a GROUP BY query) is costly to evaluate at the remote source.
例如，基于一个非常复杂的、只返回5行的查询(例如一个GROUPBY查询)的视图在远程数据源上计算起来代价较高。
You can use one of the predefined queries that are configured via parameters (for example, all WSDL documents with classifier x); and you can write your own XPath-based query.
可以使用通过参数来配置的预定义查询(例如，具有分类器x的所有WSDL)；也可以编写自己的基于XPath的查询。
For example, we created a query view based on the All Documents view in the discussion database. These are the fields that we wrote down.
例如，我们基于discussion数据库中的AllDocuments视图创建了一个查询视图。
For example, you can refine the query plan based on your database design, access time of the media, or CPU speed for your specific supported devices.
例如，您可以根据您的数据库设计、媒体的访问时间、或支持的特定设备的CPU速度来修改查询计划。
If you use dynamic queries that change based on information in your URI (when using pagination, for example), each instance of the query will produce its own cache file.
当你根据URI上的信息动态查询时(例如使用分页)，每次查询的实例将创建自己的缓存文件。
The most commonly used method for content-based video retrieval is query by example, so the video similarity measurement becomes a basal problem.
基于内容的视频检索中的一个最普遍的方法是根据给定例子视频的检索，因此视频相似度度量是基于内容检索中的一个基本问题。
