Accurately representing the statistics characteristics for a remote view is tricky.

准确地表示一个远程视图的统计特征很有技巧。

youdao

A nickname can be defined over a remote view just as it can be defined over a remote table.

可以定义远程视图的昵称，就像定义远程表的昵称一样。

youdao

For example, at Oracle, you can use the following remote view definition that will exclude the XML declaration.

例如，在Oracle，可以使用如下的远程视图定义来排除XML声明。

youdao

The table CUSTOMER_INFO is stored in a DB2 9 database, and its XML data is serialized into a BLOB column using the following remote view.

表CUSTOMER_INFO存储于DB 29数据库中，其XML数据通过如下所示的远程视图序列化进blob列。

youdao

If the remote view contains a complex query, using table-level statistics such as the cardinality for the nickname over the view can be misleading.

如果远程视图包含一个复杂的查询，那么使用表级统计信息(例如视图昵称的基数)可能使人产生误解。

youdao

For instance, you can also create a nickname over a remote view that extracts part of an XML document or the value of an element. The Oracle view below will return the content of an XML element.

比如，您也可以在远程视图之上创建昵称，这个远程视图提取部分XML文档或元素的值。
