Native queries provide a powerful way to execute complex queries without having to learn a new query language or resort to complicated object structures to model a predicate.
原生查询为执行复杂查询提供了一种功能强大的方法，而且不需要学习新的查询语言或使用复杂对象结构对谓词建模。
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。
The XMLEXISTS predicate in the original query got converted into a complex expression that can be referred to using the number Q1.
初始查询中的XMLEXISTS谓词被转换为一个复杂表达式，可以通过编号Q 1引用。
Before moving on to pseudo columns and more complex examples, I want to briefly explain where the where predicate of an Oracle recursion needs to be placed.
在讨论伪列和更复杂的例子之前，我想简要地解释一下Oracle中递归的WHERE谓词应该放在哪里。
