[英]Extracting values from XML column in Oracle
我在Oracle表中有一些数据,该数据存储在XML格式的字符串中(表WS_LOG
列response
)。
我想从<MedicalProcedureOutput>
下的每个不同节点提取数据,但是在到达每个节点时遇到了一些困难。 你能发现我在做什么错吗?
这是我正在尝试的方法(这里尝试检索icpcID
标签的值):
SELECT a.id,
t1.icpcID FROM
GH.WS_LOG a,
xmltable(
xmlnamespaces(
'http://schemas.xmlsoap.org/soap/envelope/' as "soap",
'http://www.w3.org/2001/XMLSchema' as "xsd",
'http://www.w3.org/2001/XMLSchema-instance' as "xsi"),
'/soap:Envelope/soap:Body/createBillingSubmissionForAFEBSGResponse/createBillingSubmissionForAFEBSGResult/proceduresList/MedicalProcedureOutput' passing xmltype(a.response) columns
icpcID varchar2(50) path 'ipcdId') t1
这是一些示例数据
<?xml version="1.0" encoding="UTF-8"?>
<soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
<soap:Body>
<createBillingSubmissionForAFEBSGResponse xmlns="urn:bcpcorp.net/ws/bsgFacets/FacetsBillingService">
<createBillingSubmissionForAFEBSGResult>
<status>0</status>
<outputMessage />
<statusElement />
<claimID>18E002021300</claimID>
<claimStatus>01</claimStatus>
<claimStatusReason>AGFP</claimStatusReason>
<totalChargeValue>35.0000</totalChargeValue>
<totalPayableValue>0.0000</totalPayableValue>
<paitentPaidvalue>17.5</paitentPaidvalue>
<totalDebitAmount>0</totalDebitAmount>
<proceduresList>
<MedicalProcedureOutput>
<ipcdId>011801</ipcdId>
<otherdisallowedAmountResponsibility>N</otherdisallowedAmountResponsibility>
</MedicalProcedureOutput>
</proceduresList>
</createBillingSubmissionForAFEBSGResult>
</createBillingSubmissionForAFEBSGResponse>
</soap:Body>
</soap:Envelope>
我希望得到的值是'011801'。 请注意,可能会出现多个<MedicalProcedureOutput>
节点,它们的组织方式如下:
<MedicalProcedureOutput>
<ipcdId>725013</ipcdId>
<otherdisallowedAmountResponsibility>N</otherdisallowedAmountResponsibility>
</MedicalProcedureOutput>
<MedicalProcedureOutput>
<ipcdId>725105</ipcdId>
<otherdisallowedAmountResponsibility>N</otherdisallowedAmountResponsibility>
</MedicalProcedureOutput>
您需要为主体中的所有内容声明默认名称空间,因为createBillingSubmissionForAFEBSGResponse
具有自己的未命名的xmlns
(因此为默认)声明,该声明从该节点开始使用; 所以:
SELECT a.id,
t1.icpcID FROM
GH.WS_LOG a,
xmltable(
xmlnamespaces(
default 'urn:bcpcorp.net/ws/bsgFacets/FacetsBillingService',
'http://schemas.xmlsoap.org/soap/envelope/' as "soap",
'http://www.w3.org/2001/XMLSchema' as "xsd",
'http://www.w3.org/2001/XMLSchema-instance' as "xsi"
),
'/soap:Envelope/soap:Body/createBillingSubmissionForAFEBSGResponse/createBillingSubmissionForAFEBSGResult/proceduresList/MedicalProcedureOutput' passing xmltype(a.response) columns
icpcID varchar2(50) path 'ipcdId') t1
/
ID ICPCID
---------- --------------------------------------------------
1 011801
或如您稍后显示的那样具有多个节点,他质疑这将返回:
ID ICPCID
---------- --------------------------------------------------
2 725013
2 725105
您应该使用EXTRACTVALUE
函数来解决它, 在这里您可以找到有关它的一些信息。
