任何人都可以帮我用下面的xml。我需要提取所有的xml值,如下所示。
AwarYear Comments FieldCode FieldNumber Key Value
AY2013-14 AAI: Adjusted Available Income AAI 306 Blank None Calculated
以下是XML示例。
<SchemaType xmlns:i="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://schemas.datacontract.org/process">
<AwardYear>AY2013_14</AwardYear>
<Fields>
<FieldSchema>
<Comments>AAI: Adjusted Available Income</Comments>
<DbLocation>IsirData</DbLocation>
<FieldCode>AAI</FieldCode>
<FieldNumber>306</FieldNumber>
<ReportDisplay>Data</ReportDisplay>
<ValidContent>
<ValidValueContent xmlns:d5p1="http://schemas.microsoft.com/2003/10/Serialization/Arrays">
<d5p1:KeyValueOfstringstring>
<d5p1:Key>Blank</d5p1:Key>
<d5p1:Value>None calculated</d5p1:Value>
</d5p1:KeyValueOfstringstring>
</ValidValueContent>
</ValidContent>
</FieldSchema>
</Fields>
</SchemaType>
请充分满足需求。提前致谢。

假设您在XML
列的表格中包含XML,如下所示:
DECLARE @XmlTable TABLE (ID INT NOT NULL, XMLDATA XML)
INSERT INTO @XmlTable VALUES(1, '<SchemaType xmlns:i="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://schemas.datacontract.org/process">
<AwardYear>AY2013_14</AwardYear>
<Fields>
<FieldSchema>
<Comments>AAI: Adjusted Available Income</Comments>
<DbLocation>IsirData</DbLocation>
<FieldCode>AAI</FieldCode>
<FieldNumber>306</FieldNumber>
<ReportDisplay>Data</ReportDisplay>
<ValidContent>
<ValidValueContent xmlns:d5p1="http://schemas.microsoft.com/2003/10/Serialization/Arrays">
<d5p1:KeyValueOfstringstring>
<d5p1:Key>Blank</d5p1:Key>
<d5p1:Value>None calculated</d5p1:Value>
</d5p1:KeyValueOfstringstring>
</ValidValueContent>
</ValidContent>
</FieldSchema>
</Fields>
</SchemaType>')
然后您可以使用此T-SQL语句来获取值:
;WITH XMLNAMESPACES(DEFAULT 'http://schemas.datacontract.org/process',
'http://schemas.microsoft.com/2003/10/Serialization/Arrays' AS ns1)
SELECT
AwardYear = XmlData.value('(SchemaType/AwardYear)[1]', 'varchar(25)'),
Comments = XmlData.value('(SchemaType/Fields/FieldSchema/Comments)[1]', 'varchar(50)'),
FieldCode = XmlData.value('(SchemaType/Fields/FieldSchema/FieldCode)[1]', 'varchar(10)'),
FieldNumber = XmlData.value('(SchemaType/Fields/FieldSchema/FieldNumber)[1]', 'int'),
[Key] = XmlData.value('(SchemaType/Fields/FieldSchema/ValidContent/ValidValueContent/ns1:KeyValueOfstringstring/ns1:Key)[1]', 'varchar(10)'),
[Value] = XmlData.value('(SchemaType/Fields/FieldSchema/ValidContent/ValidValueContent/ns1:KeyValueOfstringstring/ns1:Value)[1]', 'varchar(10)')
FROM
@XmlTable
我将顶级XML命名空间定义为“默认”命名空间(不需要在整个地方引用),并且结构内部的第二个命名空间使用单独的XML命名空间前缀显式定义。
