谁能帮我<QuoteId>使用 T-SQL 和 XQuery 从附加的 XML 文件中检索一个值？

我正在尝试使用这个 T-SQL 但没有运气

declare @QuoteResponse XML
select @QuoteResponse =gQuoteResponse FROM AutoRenew where policyid= '454544'

SELECT b.value('(OverallResultStatus)[1]', 'varchar(100)')  as status
FROM
@QuoteResponse.nodes('GetQuoteResponse/OperationResult') as a(b)

这是我用来检索QuoteId

DECLARE @QuoteResponse XML

SELECT @QuoteResponse = gQuoteResponse FROM [dbo].[AutoRenew] WHERE policyid = '454544'

SELECT
    @QuoteResponse.value('(GetQuoteResponse/QuoteResults/QuoteResult/QuoteId)[1]', 'bigint')

谢谢

这个怎么样：

DECLARE @QuoteResponse XML
SELECT @QuoteResponse = gQuoteResponse FROM dbo.AutoRenew WHERE policyid = '454544'

SELECT
    @QuoteResponse.value('(/GetQuoteResponse/QuoteResults/QuoteResult/QuoteId)[1]', 'bigint')

您只需要遵循 XML 元素层次结构 - 直到您读取所需的值：

<GetQuoteResponse     -- this one is relevant ....
        xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
        xmlns:xsd="http://www.w3.org/2001/XMLSchema">
  <OperationResult>  -- irrelvant - not in here.....
    ......
  </OperationResult>
  <QuoteResults>       -- this one is relevant ....
    <QuoteResult>      -- this one is relevant ....
      <OperationResult>  -- irrelvant - not in here..... 
        ....
      </OperationResult>
      <MainData>   -- irrelvant - not in here..... 
        ......
      </MainData>
      <Price>    -- irrelvant - not in here..... 
        ......
      </Price>
      <QuoteId>322423234</QuoteId>   -- here's our value !

您是否尝试过创建临时表然后使用 openxml 填充临时表？

DECLARE @QuoteResponse XML
SELECT @QuoteResponse =gQuoteResponse FROM AutoRenew where policyid= '454544'

DECLARE @idoc INT
EXEC sp_xml_preparedocument @idoc OUTPUT, @QuoteResponse

CREATE TABLE #QuoteIds(   
    [QuoteId] VARCHAR (10))

INSERT INTO #QuoteIds ([QuoteId])
    SELECT QuoteId
    FROM OPENXML(@idoc, '/QuoteResults/QuoteResult/QuoteId', 2) WITH #QuoteIds

DECLARE @quoteid VARCHAR (10)
SET @quoteid = (SELECT TOP 1 QuoteId FROM #QuoteIds)
