使用T-SQL解析连续性护理文档（CCD）

我已经想出如何使用T-SQL对CCD进行一些基本的解析，并认为我会分享结果。

如果有人知道更好的方法，请随时发表评论。我特别感兴趣的是减少与命名空间声明相关的文本。

我知道我可以简单地从原始xml中删除命名空间（xmlns =“urn：hl7-org：v3”），但是，我宁愿不这样做。

一个微不足道的变化，至少可以帮助减少换行：

DECLARE @namespace varchar(75);
SET @namespace = 'declare default element namespace "urn:hl7-org:v3";';

SELECT 
   Field.value(@namespace + 'title[1]', 'varchar(255)') AS Title,
   ...

您可以使用WITH XMLNAMESPACES。

WITH XMLNAMESPACES(DEFAULT 'urn:hl7-org:v3')
SELECT
    Field.value('title[1]', 'varchar(255)') AS Title,
    Field.value('(recordTarget/patientRole/id/@extension)[1]', 'varchar(255)') AS InternalPatientID,
    Field.value('(effectiveTime/@value)[1]', 'varchar(255)') AS CreationDateTime,
    Field.value('(recordTarget/patientRole/patient/name/name)[1]', 'varchar(255)') AS FullName,
    Field.value('(recordTarget/patientRole/patient/name/family)[1]', 'varchar(255)') AS LastName,
    Field.value('(recordTarget/patientRole/patient/name/given)[1]', 'varchar(255)') AS FirstName,
    Field.value('(recordTarget/patientRole/patient/name/given)[2]', 'varchar(255)') AS MiddleName,
    Field.value('(recordTarget/patientRole/patient/birthTime/@value)[1]', 'varchar(255)') AS DateOfBirth,
    Field.value('(recordTarget/patientRole/patient/administrativeGenderCode/@code)[1]', 'varchar(255)') AS Gender,
    Field.value('(recordTarget/patientRole/addr/streetAddressLine)[1]', 'varchar(255)') AS PatientAddress,
    Field.value('(recordTarget/patientRole/addr/streetAddressLine)[2]', 'varchar(255)') AS PatientAddress2,
    Field.value('(recordTarget/patientRole/addr/city)[1]', 'varchar(255)') AS PatientCity,
    Field.value('(recordTarget/patientRole/addr/state)[1]', 'varchar(255)') AS PatientState,
    Field.value('(recordTarget/patientRole/addr/postalCode)[1]', 'varchar(255)') AS PatientZip,
    Replace(Field.value('(recordTarget/patientRole/telecom/@value)[1]', 'varchar(255)'), 'tel:', '') AS HomePhone
FROM @ClinicalDocumentXml.nodes('ClinicalDocument') CCD(Field)

您还可以使用cross apply。

缩短一点 
WITH XMLNAMESPACES(DEFAULT 'urn:hl7-org:v3')
SELECT
    CD.Field.value('title[1]', 'varchar(255)') AS Title,
    PR.Field.value('(id/@extension)[1]', 'varchar(255)') AS InternalPatientID,
    CD.Field.value('(effectiveTime/@value)[1]', 'varchar(255)') AS CreationDateTime,
    PR.Field.value('(patient/name/name)[1]', 'varchar(255)') AS FullName,
    PR.Field.value('(patient/name/family)[1]', 'varchar(255)') AS LastName,
    PR.Field.value('(patient/name/given)[1]', 'varchar(255)') AS FirstName,
    PR.Field.value('(patient/name/given)[2]', 'varchar(255)') AS MiddleName,
    PR.Field.value('(patient/birthTime/@value)[1]', 'varchar(255)') AS DateOfBirth,
    PR.Field.value('(patient/administrativeGenderCode/@code)[1]', 'varchar(255)') AS Gender,
    PR.Field.value('(addr/streetAddressLine)[1]', 'varchar(255)') AS PatientAddress,
    PR.Field.value('(addr/streetAddressLine)[2]', 'varchar(255)') AS PatientAddress2,
    PR.Field.value('(addr/city)[1]', 'varchar(255)') AS PatientCity,
    PR.Field.value('(addr/state)[1]', 'varchar(255)') AS PatientState,
    PR.Field.value('(addr/postalCode)[1]', 'varchar(255)') AS PatientZip,
    Replace(PR.Field.value('(telecom/@value)[1]', 'varchar(255)'), 'tel:', '') AS HomePhone
FROM
  (SELECT @ClinicalDocumentXml.query('/ClinicalDocument/*')) AS CD(Field)
CROSS APPLY
  (SELECT CD.Field.query('recordTarget/patientRole/*')) AS PR(Field)
