SQL Server 2008 R2 SP2函数用于提取xml数据

时间：2014-06-20 00:55:36

标签： sql xml xpath sql-server-2008-r2

我目前有一个功能可以从CCD中提取患者编号，但CCD包含MRN, EMPI, SSN和患者编号。我需要它来提取患者编号而不是EMPI。然后我将使用它来利用RETURN创建一个列。

请帮助！

这是当前代码：

CREATE FUNCTION [dbo].[rs_ExtractPatientIdentifier] 
    (@xmlData xml, @messageType nvarchar(50))
RETURNS 
    nvarchar(128)
WITH SCHEMABINDING
BEGIN
    DECLARE @patientIdentifier nvarchar(128)

    ;WITH XMLNAMESPACES(DEFAULT 'http://domain.com/product/Schemas', 'urn:hl7-org:v3' as hl7ns)
    SELECT 
       @patientIdentifier = CASE @messageType
                               WHEN 'CCD' THEN @xmlData.value('(hl7ns:ClinicalDocument/hl7ns:recordTarget/hl7ns:patientRole/hl7ns:id/@extension)[1]', 'varchar(128)')
                               WHEN 'PatientAdverseReactionRequest' THEN @xmlData.value('(PatientAdverseReactionRequest/Patient/Identifiers/Identifier/Id)[1]', 'varchar(128)')
                               WHEN 'UnsolicitedDocumentType' THEN @xmlData.value('(DocumentManagementRequest/Patient/Identifiers/Identifier/Id)[1]', 'varchar(128)')
                               WHEN 'UnsolicitedLabResult' THEN @xmlData.value('(UnsolicitedLabResult/Patient/Identifiers/Identifier/Id)[1]', 'varchar(128)')
                               ELSE ''
                             END

    RETURN @patientIdentifier
END

以下是具有患者ID的XML，我需要将其作为本地定义的患者ID：

答案 0 :(得分：0)

您的陈述

WHEN 'CCD' THEN @xmlData.value('(hl7ns:ClinicalDocument/hl7ns:recordTarget/
                  hl7ns:patientRole/hl7ns:id/@extension)[1]', 'varchar(128)')
正如你所说，

选择第一个patientRole / id / @扩展名（因为[1]）。但是你想要本地定义的患者ID，即

  <id assigningAuthorityName="Hospital: Locally defined Patient Account Number" 
       extension="000222222222" root="1.3.6.1.4.1.26923.99.1.1.44273.7.3"/>

因此，您可以根据assigningAuthorityName属性的值更改WHEN语句的XPath表达式：

WHEN 'CCD' THEN @xmlData.value('(hl7ns:ClinicalDocument/hl7ns:recordTarget/
   hl7ns:patientRole/hl7ns:id[
      assigningAuthorityName="Hospital: Locally defined Patient Account Number"]/
     @extension)[1]', 'varchar(128)')

（分手，所以你不必侧身滚动）。

这将为您提供@extension为<id> assigningAuthorityName的第一个"Hospital: Locally defined Patient Account Number"的{​​{1}}。
