Question

我正在尝试将SQL查询转换为XML文件。但是，我遇到了包含“ CompliesWith”的“ Compliance”问题，如下所示。发生的是有多个“ CompliesWith”，而不是在“ Compliance”中有4行，而是进行迭代。有谁知道如何纠正这个问题？请参阅下面的查询和XML输出。

Answer 1

对于下一个问题：请减少您的输入到所需的最小值。最好的做法是创建一个独立样本，该样本使用最少的输入数据以及您自己的尝试和预期的输出，以重现您的问题。

如果我正确理解，一切正常，但这是

     , (
         select [CompliesWith] = cw.name
         from SpecCompliesWithJoin cwj
           join CompliesWith cw on cwj.fkCompliesWith = cw.pkid 
                               and cw.langID = 0
         where ss.SpecID = cwj.fkSpec 
         FOR XML RAW ('CompliesWith'), TYPE, ROOT('Compliance'), ELEMENTS
       )

我认为您可以将最后一行更改为

         FOR XML PATH (''), TYPE, ROOT('Compliance'), ELEMENTS

另一个机会是使用

创建一个无名元素

         select [*] = cw.name

提示：在大多数情况下，FOR XML PATH优于RAW，AUTO或EXPLICIT ...

将SQL查询格式化为XML文件
