查询关系中封装映射时,可通过在运行时支持修改映射来提供可重用性和提高灵活性。
Encapsulating the mapping in a lookup relationship makes it reusable and increases flexibility by enabling modification of the mapping data at runtime.
IBM提供的XQuery函数允许查询关系数据,并与来自支持XML的列的XML结果组合在一起。
IBM provides XQuery functions that allow you to query relational data and mix and match the results with the XML from the XML-aware columns.
通过在源属性和目标属性之间绘制RelationshipLookup转换,即可应用查询关系。
Lookup relationships are applied by drawing a relationship Lookup transformation between a source and target property.
此转换类型是ProcessServerV6.1 中新推出的,仅能将其用于身份查询关系。
This transformation type is new in Process Server V6.1; you can use it for identity lookup relationships only.
例如,邮政编码查询关系可以将电话区号“650”映射到邮政编码“94010”、“94305”等。
For example, a zip code lookup relationship might map the phone area code "650" to the zip codes "94010," "94305," and so on.
与所存储的表一样,该关系查询的结果也是平面的、规则的、同构的。
Like a stored table, the result of a relational query is flat, regular, and homogeneous.
请对大多数查询和动态关系使用此选项。
一旦要在给定的查询中使用关系,就可以采用热加载技术。
You can use the eager loading technique whenever you know that you will use relationships in a given query.
您可以设置主要关键字,创建并编辑查询,添加并删除关系,以及设置一个同步列。
You can set primary keys, create and modify queries, add and remove relationships, and set a concurrency column.
在引出箭头上执行相同的操作将为引出的关系提供查询。
Doing the same on the outgoing arrow provide queries for outgoing relationships.
而在关系查询语言中,该查询表示起来将会困难得多。
This query would be much more difficult to represent in a relational query language.
DB 2 9.7中的查询优化技术能够提高针对XML数据的关系视图的查询处理效率。
Query optimization technology in DB2 9.7 provides increased efficiency for processing queries against relational views of XML data.
这种优化特性让应用程序能够使用SQL查询通过传统的关系接口高效地查询XML数据。
This optimization feature enables applications to efficiently query XML data through a traditional relational interface with SQL queries.
如果XML数据被分解到关系表,那么关系查询结果必须被转换回xML。
If the XML data is shredded to relational tables, relational query results must be converted back to XML.
然后,当应用程序将一个地址转换为另一个地址时,通过查询StateCode关系,就可以在州名称和州代码之间进行转换。
Then, when an application transforms one address into another address, it can transform state names into state codes, and vice versa, by querying the StateCode relationship.
以简单的方式同时查询存储的XML和关系数据
To query stored XML and relational data together in a straightforward way
在Viper2中,这个限制已经消除了,现在可以向XQuery中嵌入的关系查询传递运行时变量。
In Viper 2, this limitation has been removed and now you are able to pass a runtime variable to a relational query embedded inside the XQuery.
这是一个好计划——但是它与前面的查询有什么关系呢?
Nice plan - but what does it have to do with the query above? Do a who-is-who in this plan.
XQuery没有类似于关系查询中 “between”谓词的专用功能或操作符。
XQuery does not have a special function or operator similar to the relational "between" predicate.
获得关系以及已命名查询的支持
我们将研究这两个环境在应用程序代码、数据库查询和关系模式方面的差异。
We will explore the difference in the application code, database queries and the relational schemas for the two environments.
这个查询系统包括相互之间的关系,加上您所选择的查询方向和深度。
