鉴于这种XML:插入复杂的XML到SQL Server表
<Documents>
<Batch BatchID="1" BatchName="Fred Flintstone">
<DocCollection>
<Document DocumentID="269" FileName="CoverPageInstructions.xsl">
<MergeFields>
<MergeField FieldName="A" Value="" />
<MergeField FieldName="B" Value="" />
<MergeField FieldName="C" Value="" />
<MergeField FieldName="D" Value="" />
</MergeFields>
</Document>
<Document DocumentID="6" FileName="USform8802.pdf">
<MergeFields>
<MergeField FieldName="E" Value="" />
<MergeField FieldName="F" Value="" />
<MergeField FieldName="G" Value="" />
<MergeField FieldName="H" Value="" />
<MergeField FieldName="I" Value="" />
</MergeFields>
</Document>
<Document DocumentID="299" FileName="POASIDE.TIF">
<MergeFields />
</Document>
</DocCollection>
</Batch>
<Batch BatchID="2" BatchName="Barney Rubble">
<DocCollection>
<Document DocumentID="269" FileName="CoverPageInstructions.xsl">
<MergeFields>
<MergeField FieldName="A" Value="" />
<MergeField FieldName="B" Value="" />
<MergeField FieldName="C" Value="" />
<MergeField FieldName="D" Value="" />
</MergeFields>
</Document>
<Document DocumentID="6" FileName="USform8802.pdf">
<MergeFields>
<MergeField FieldName="E" Value="" />
<MergeField FieldName="F" Value="" />
<MergeField FieldName="G" Value="" />
<MergeField FieldName="H" Value="" />
<MergeField FieldName="I" Value="" />
</MergeFields>
</Document>
</DocCollection>
</Batch>
</Documents>
我试图实现这一结果:
BatchID BatchName DocumentID FieldName
1 Fred Flintstone 269 A
1 Fred Flintstone 269 B
1 Fred Flintstone 269 C
1 Fred Flintstone 269 D
1 Fred Flintstone 6 E
1 Fred Flintstone 6 F
1 Fred Flintstone 6 G
1 Fred Flintstone 6 H
1 Fred Flintstone 6 I
1 Fred Flintstone 299 Null
2 Barney Rubble 269 A
2 Barney Rubble 269 B
2 Barney Rubble 269 C
2 Barney Rubble 269 D
2 Barney Rubble 6 E
2 Barney Rubble 6 F
2 Barney Rubble 6 G
2 Barney Rubble 6 H
2 Barney Rubble 6 I
我似乎得到一个笛卡儿连接本(每个文档有跨所有文件的MergeField的完整列表:
SELECT lvl1.n.value('@BatchID','int'),
lvl1.n.value('@BatchName','varchar(50)'),
lvl2.n.value('@DocumentID','int'),
lvl3.n.value('@FieldName','varchar(50)')
FROM @Data.nodes('Documents/*') lvl1(n)
CROSS APPLY lvl1.n.nodes('DocCollection/Document') lvl2(n)
CROSS APPLY lvl1.n.nodes('DocCollection/Document/MergeFields/MergeField') lvl3(n)
我想知道如何得到我需要的结果,用空值va适用于没有MergeField元素的批1中的299 DocumentID。
任何帮助表示赞赏。

UPDATE:以下是如何做到使用的OpenXML相同:
SELECT
BatchID,
BatchName,
DocumentID,
FileName,
KeyData,
FieldName
FROM OPENXML(@hdoc, '/Documents/Batch/DocCollection/Document/MergeFields/MergeField', 11)
WITH (BatchID varchar(100) '../../../../@BatchID',
BatchName varchar(100) '../../../../@BatchName',
DocumentID varchar(100) '../../@DocumentID',
FileName varchar(100) '../../@FileName',
KeyData varchar(100) '../../@KeyData',
FieldName varchar(100) '@FieldName');
谢谢(再次)约翰。太棒了。我无法相信我在这个项目中遇到的XML问题。 – CarlGanz
@CarlGanz乐于助人。我也是XML的后期用户。我看snugo,他是xml忍者 –
