对不起,如果这是在其他地方,我发现了很多类似的例子,但我一直无法使用我的数据.2天后,我需要一个答案:(

基本上有一个SQL Server表,其中包含一个包含XML数据的列.此数据包含我需要提取的值.

这是我的XML.

  <CustomFields xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns="http://www.kaseya.com/vsa/2007/12/ServiceDeskDefinition.xsd">
    <Field fieldName="AutoCategory">Event Log</Field>
    <Field fieldName="SType">Event Log</Field>
    <Field fieldName="STag1">AgentGuid</Field>
    <Field fieldName="STag2">AlertRegistrationId</Field>
    <Field fieldName="STag3">LogType</Field>
    <Field fieldName="SValue1">619764177412541</Field>
    <Field fieldName="SValue2">104</Field>
    <Field fieldName="SValue3">1380569194</Field>
    <Field fieldName="SdTicketId">RPSv1006330</Field>
    <Field fieldName="AgentName">bla bla</Field>
    <Field fieldName="MachineGroupGuid">86115414719112271316891312</Field>
    <Field fieldName="OrgFk">59165166782128125214185317</Field>
    <Field fieldName="GuidAgent">619764177412541</Field>
    <Field fieldName="AlertCount">0</Field>
    <Field fieldName="TicketTitle">bla bla</Field>
    <Field fieldName="LegacyId">152262</Field>
    <Field fieldName="LegacyRef">152262</Field>
    <Field fieldName="CwStatus">2</Field>
    <Field fieldName="CwTicketId">89495</Field>
</CustomFields>

我需要能够提取与CwTicketId字段名称关联的值.

所以从本质上讲,我想通过XML来查找带有fieldName = "CwTicketId"和返回的节点89495或等价值.

下面是我自己提出的代码,它将值拉出来,但问题是有时XML的排序方式不同,因此值并不总是在我指定的行上,因此它返回准确的数据.

;WITH XMLNAMESPACES(DEFAULT N'http://www.kaseya.com/vsa/2007/12/ServiceDeskDefinition.xsd')
SELECT 
    ref as ServiceDeskID, 
    sdSummary as ServiceDeskSummary,
    customFields.value('(/CustomFields/Field/node())[17]', 'varchar(100)') as LegacyIDTicketing,
    customFields.value('(/CustomFields/Field/node())[19]', 'varchar(100)') as CWIDTicketing …

我必须获取公司节点元素的值。我已经尝试了所有从节点获取数据的方法，但没有成功。下面是我的 XML。

<?xml version="1.0"?>
    <CompanyInvoice xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
      <Customer xmlns="http://t.service/CompanyServices/">
        <Company>
          <CompanyId>10001</CompanyId>
          <CoastalId>454564564564564564564564565465454546565555555</CoastalId>
          <CompanyFederalId>345345</CompanyFederalId>
          <CompanyName>Anytime Home</CompanyName>
          <CompanyAddress>Address1</CompanyAddress>
          <CompanyCity>TR</CompanyCity>
          <CompanyState>UT</CompanyState>
          <CompanyPostalCode>11</CompanyPostalCode>
          <CompanyCountry>IT</CompanyCountry>
          <CompanyTelephone>(999) 999-9999</CompanyTelephone>
        </Company>
        <CustomerId>33642</CustomerId>    
      </Customer>
      </CompanyInvoice>

TSQL 代码：我只是尝试过这个，但没有得到任何更新
