在参与分布式查询的所有数据库中，各种数据类型必须定义有相同的层次结构和类型转换。
The distinct data types must have exactly the same hierarchy and casts defined in all databases participating in the distributed queries.
假设上面示例中的COL1列上有索引，如果对COL1而不是RHS执行类型转换，那么会绕过索引，查询会执行全表扫描。
If you assume that there is an index on COL1 in the above example, if COL1 is type-cast instead of the RHS, then the index will be bypassed and the query will perform a full table scan.
下面几个小节提供了关于如何使用联邦服务器来处理在线商店场景中可能出现的不同类型查询的例子。
The following sections provide some examples of how you could use the federated server to process various kinds of queries that might come up in the online store scenario.

XQuery是一种高端的、强类型的函数语言(没有副作用)，非常适合表达从XML文档或者大型XML存储库(repository)中获取数据的查询。
XQuery is a high-level, strongly-typed, functional language (free of side-effects) that is ideal to express a query to obtain data both from an XML document and a large XML document repository.
xml索引和查询谓词中的数据类型。
select语句通常是运行在典型web应用程序中的最常见的查询类型。
SELECT statements are usually overwhelmingly the most common types of queries run in a typical web application.
第一层防御是在数据库的查询中总是包含文件类型和来自磁盘上实际文件的模式位 (mode bits)，而不只包含文件的设备和inode 号。
The first layer of defense is that queries to the database always include the file type and mode bits from the real file on disk, not just the device and inode.
然而，在地址查询Web服务中，WSDL文件中的location数据类型包含2个名为和的元素，而没有任何意义说明信息。
However, in the Address Finder Web Service, the location data type in the WSDL file contains the elements named as and without any meaning.
