我正在尝试从XML字符串插入数据

<customer ID="1">
 <Value HNAME="Holand" Revenue="12,7865"/>
 <Value XNAME="Hemmer" Revenue="15,7865"/>
 82 more "Value" child with different set of revenue and <AlphabetCombinations>NAME values.....
<customer>

您认为只更新已更改的列更有效吗。我想，如果在比较之前讨论解析XML的两个方面，效率会更低…谢谢…Aaron Bertrand。。

<customer ID="1">
 <Value HNAME="Holand" Revenue="12,7865"/>
 <Value XNAME="Hemmer" Revenue="17,7425"/>
 82 more "Value" child with different set of revenue and <AlphabetCombinations>NAME values.....
