[英]How to read XML column in SQL Server 2008?
我從未在SQL Server 2008中使用過XML,我需要將字段列表提取到變量表中,您該怎么做?
假設我在XMLMain表中有一列名為xmldata的列,如下所示,該如何提取sql中的字段列表?

<my:field1>1</my:field1>
<my:field2>2</my:field2>
<my:field3>true</my:field3>
<my:field4 xsi:nil="true" />
<my:field5 xsi:nil="true" />
<my:field6>4</my:field6>
<my:FormName>2014-04-01T15:11:47</my:FormName>
<my:Repeating>hi</my:Repeating>
<my:Repeating xmlns:my="http://schemas.microsoft.com/office/infopath/2003/myXSD/2014-03-29T09:41:23">hello</my:Repeating>
<my:Repeating xmlns:my="http://schemas.microsoft.com/office/infopath/2003/myXSD/2014-03-29T09:41:23">how are you?</my:Repeating>
</my:myFields>
我想提取重復字段的值作為逗號分隔,如前。 在重復中,我們有三個值(嗨,你好,你好嗎?)
誰能幫幫我嗎。?
with xmlnamespaces('http://schemas.microsoft.com/office/infopath/2003/myXSD/2014-03-29T09:41:23' as my)
select M.XMLData.value('(/my:myFields/my:field1/text())[1]', 'int') as field1,
M.XMLData.value('(/my:myFields/my:field2/text())[1]', 'int') as field2,
M.XMLData.value('(/my:myFields/my:field3/text())[1]', 'bit') as field3,
M.XMLData.value('(/my:myFields/my:FormName/text())[1]', 'datetime') as FormName,
(
select ','+R.X.value('text()[1]', 'nvarchar(max)')
from M.XMLData.nodes('/my:myFields/my:Repeating') as R(X)
for xml path(''), type
).value('substring(text()[1], 2)', 'nvarchar(max)') as Repeating
from XMLMain as M
結果:
field1 field2 field3 FormName Repeating
