SQL Server 查询元素值的 xml 属性 [英] SQL Server query xml attribute for an element value

问题描述

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:(

Sorry if this is somewhere else, I have found a lot of similar examples but I have been unable to get it working with my data. 2 days later and I need an answer :(

基本上有一个 SQL Server 表，其中有一列包含 XML 数据.此数据包含我需要提取的值.

Basically have a SQL Server table with a column containing XML data. This data contains values I need to extract.

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.

I need to be able to pull out the value associated to the CwTicketId field name.

所以本质上，我想通过 XML 查找具有 fieldName = "CwTicketId" 的节点并返回 89495 或等效值.

So in essence, I want to look through the XML to find the node with fieldName = "CwTicketId" and to return 89495 or equivalent value.

下面是我自己想出的代码，它提取值，但问题是有时 XML 的顺序不同，所以值并不总是在我指定的行上，因此它以准确的数据返回.

Below is the code I have come up with myself, which pulls values out, but the problem is sometimes the XML is ordered differently, so the values are not always on the line that I have specified, hence it returns in accurate data.

;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
FROM 
    [ksubscribers].[kasadmin].[SDIncident]

我也需要第二个值，但如果我能弄清楚如何提取一个值，我可以复制另一个值.

The second value I also need, but if i can figure out how to pull one value out, I can duplicate for the other.

希望有人能帮忙，因为我已经开始脱发了！

Hope someone can help as I have started ripping my hair out!

感谢您的帮助！！
