对称的操作符，如算术操作符、相等操作符、关系操作符和位操作符，最好定义为普通非成员函数。

该操作符还从时间戳提取日期和时间信息，并用一个XML数据值填充两个关系列。
This operator also extracts the date and time information from a timestamp, populating two relational columns from one XML data value.
注意：当索引表达式被用于关系表达式，或作为某个操作符类函数的参数时，查询优化器将考虑使用函数索引。
Note: the query optimizer considers using a functional index when the index expression is used in a relational expression or as an argument to one of the operator class functions.
第二个操作符从不同的xml节点提取一些关系列值。
The second operator extracts a number of relational column values from various XML nodes.
操作可以是一个关系运算符，或者系统或用户定义的函数，也可以是一个sql操作符，例如GROUPBY、ORDER BY等。
An operation can be a relational operator, a system - or user-defined function, or an SQL operator, such as GROUP BY, ORDER BY, and so on.
一个IXAND计划，其中所有合适的关系和xml索引出现在IXAND操作符下。
An IXAND plan with all applicable relational and XML indexes appearing under the IXAND operator.
在OmniFind 中，与该概念关系最密切的映射是-符号，其在大多数情况下是可用于搜索的 “异”运算操作符，但是不会生成它自己的结果。
In OmniFind, the closest mapping to this concept is the - symbol, which is more of an exclusion operator that can be applied to the search, but will not generate results of its own.
这里没有与每个RPD操作符相关的sql语句，因为ORDERS和ORDER_ITEMS不是关系昵称。
There is no SQL statement associated with each of the RPD operators because ORDERS and ORDER_ITEMS are not relational nicknames.
RPD操作符中的远程访问计划是由包装器构造的，其中包含为调用来自非关系数据源的远程请求所需的规范。
The remote access plan contained in the RPD operator is constructed by the wrapper and contains the necessary specification to invoke the remote request from the non-relational data source.
类似于现有的用于关系索引的关系索引扫描操作符(IXSCAN)，XISCAN操作符在xml索引上执行查找或扫描。
Like the existing relational index scan operator for relational indexes (IXSCAN), the XISCAN operator performs lookups or scans on XML indexes.
在保存完成的混搭之前，应在所有使用关系型更新数据源的source操作符中关闭缓存。
Just before saving the completed mashup, you should turn off caching in all source operators that use relational update feeds.
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.
这个提取器操作符能从pmml模型(由associations操作符创建)提取关联规则并通过关系表结构提供这些规则。
The extractor operator will extract the association rules form the PMML model created by the Associations operator and provides them in a relational table structure.
