在这里,我已经解决了许多有关此问题的问题,而这些决议似乎都无效。我有以下XML:
DECLARE @XML xml;
SELECT @XML ='<?xml version="1.0" encoding="UTF-8"?>
<hb:MedicalAidMessage xmlns:hb="bridge.co.za/mes" Version="6.0.0">
<Claim>
<Details>
<LineItems>
<LineItem>
<HBBatchNum>2414</HBBatchNum>
</LineItem>
</LineItems>
</Details>
</Claim>
</hb:MedicalAidMessage>';
和此代码进行解析:
;WITH XMLNAMESPACES ('bridge.co.za/mes' as ns)
SELECT
ISNULL(T.N.value('HBBatchNum[1]', 'INT'), 0) AS BatchNo
FROM
@XML.nodes('/Claim/Details/LineItems/LineItem[1]') AS T(N)
这将返回空白值而不是2414。在实时查询中,XML存储在表列中。我只是无法弄清楚为什么我没有得到节点值。
答案 0 :(得分:4)
很明显……Claim
不是根元素。因此,请使用以下之一:
WITH XMLNAMESPACES ('bridge.co.za/mes' AS ns)
SELECT ISNULL(T.N.value('HBBatchNum[1]', 'int'),0) AS BatchNo
FROM @XML.nodes('/ns:MedicalAidMessage/Claim/Details/LineItems/LineItem[1]') AS T(N)
-- WITH XMLNAMESPACES ('bridge.co.za/mes' AS ns)
SELECT ISNULL(T.N.value('HBBatchNum[1]', 'int'),0) AS BatchNo
FROM @XML.nodes('/*:MedicalAidMessage/Claim/Details/LineItems/LineItem[1]') AS T(N)
