This functionality is built upon the virtual table interface (VTI) provided by IDS.
该功能建立在IDS提供的虚表接口（VTI）之上。
As you can see, the optimizer creates a virtual table to process the IN-list sub-query.
如您所见，优化器创建了一个虚拟表来处理in列表子查询。
Informix provides access to external data sources through the virtual table interface (VTI).
Informix通过虚拟表接口(VTI)提供对外部数据源的访问。
These must match in position and data type with the columns in the virtual table CATEGORIZED.
这些字段必须在位置和数据类型方面与虚拟表CATEGORIZED中的列相匹配。
This creates a virtual table by the name "CATEGORIZED" with a set of columns supplied from inner queries.
该部分创建了一个名称为“CATEGORIZED”的虚拟表，表中带有inner查询提供的一组列。
After seeing the TimeSeries functions and casts and other elements, a virtual table looks like an easy choice.
看过了TimeSeries函数和强制类型转换以及其他元素之后，虚表看上去是一种自然的选择。
Finally, a virtual table tennis experiment is designed to verify the systemic high performance and validity of the strategy.
通过一个虚拟乒乓球掂球实验验证了本系统的高性能与控制方法的有效性。
It can be very slow to do queries across a virtual table, especially if you use one of the TimeSeries elements in the WHERE clause.
虚表上的查询可能非常慢，尤其是在where子句中使用某个TimeSeries元素时更是如此。
Instead, use a virtual table with a WHERE clause, or define the join as a view in the data source, and execute the rule on this view.
相反，可使用具有where子句的虚拟表，或者将连接作为数据源的视图进行定义，并在这一视图中执行规则。
Also, I have occasionally encountered strange results from virtual table queries that do not occur when I use the direct TimeSeries functions.
而且，虚表查询偶尔还会返回奇怪的结果，而在使用TimeSeries函数时不会碰到这种情况。
Every object has some additional bytes that the common language runtime USES to manage the object, such as the object's virtual table pointer and a reference to a sync block.
每个对象都有一些附加字节，通用语言运行库用来管理对象，如对象的虚表指针和同步锁定引用。
You can effectively reduce the number of records that are read from the source, and reduce the overall execution time of a rule, by defining a virtual table with a filter condition.
您可通过定义具有过滤条件的虚拟表，来有效地减少从源所读取记录的数量，并减小规则的总执行时间。
