Complete the following steps to add the second XML Relational Mapping operator.

完成以下步骤，添加第二个XMLRelationalmapping操作符。

youdao

Edit the XML Relational Mapping operator, deleting all column definitions except those required by the target table.

编辑XMLRelationalmapping操作符，删除目标表不需要的所有列定义。

youdao

Map the appropriate source columns from the XML Relational Mapping operator to the target columns of the table, as shown in Figure 22.

将来自xmlRelationalmapping操作符的适当的源列映射到该表的目标列，如图22所示。

youdao

Because XML columns cannot participate in Group By clauses, you need to define a second XML Relational Mapping operator (shown on the upper branch of Figure 1).

因为xml列不能参与groupBy子句，所以需要定义第二个XMLRelationalMapping操作符(图1中上方的分支)。

youdao

This data flow simply reads the XML data from the source table and uses a single XML Relational Mapping operator to populate the target table directly, as shown in Figure 2.

这个数据流从源表中读取XML 数据，然后使用一个 XMLRelationalMapping操作符直接填充目标表，见图 2。
