Question

我对XML很新，我被要求使用SQL创建XML格式的数据文件。我需要查询数据库中的多个表以获取所有必要的信息，并需要合并XML输出中的信息。我正在努力解决如何以预期的格式整合数据。任何和所有建议/帮助非常感谢。谢谢！这是我正在测试的查询 -

(select
    p.acctno as [Demographic/PatientID],
    p.patdob as [Demographic/DOB],
    c.poscode as [Procedure/Facility],
        (select
            CAST(c.acctno as varchar(10)) +
                 CONVERT(varchar(10), c.dateofservice, 112) as [AnesthesiaRecordID],
            (select
                d.provcode as [AnesthesiaStaff/ProvCode]
            FOR XML PATH ('AnesthesiaStaffSet'), TYPE
            )
        FOR XML PATH ('AnethesiaCase'), TYPE
        )
    from patdemo_t p
        inner join charge_t c on p.acctno = c.acctno
        inner join provcode_t d on c.provcode = d.provcode
    where
        p.acctno in (12345, 54321) 
        and c.dateofservice in ('2018-02-15','2018-02-01')
    group by p.acctno, c.poscode, p.patdob, p.patfname,
             p.patlname, c.acctno, c.dateofservice, d.provcode
)
FOR XML PATH ('AnesthesiaRecord'), ROOT('AnesthesiaRecords'), TYPE

我的输出是这样的 -

<AnesthesiaRecords>
  <AnesthesiaRecord>
    <Demographic>
      <PatientID>12345</PatientID>
      <DOB>1972-03-30T00:00:00</DOB>
    </Demographic>
    <Procedure>
      <Facility>LHOP </Facility>
    </Procedure>
    <AnethesiaCase>
      <AnesthesiaRecordID>1234520180201</AnesthesiaRecordID>
      <AnesthesiaStaffSet>
        <AnesthesiaStaff>
          <ProvCode>BUS</ProvCode>
        </AnesthesiaStaff>
      </AnesthesiaStaffSet>
    </AnethesiaCase>
  </AnesthesiaRecord>
  <AnesthesiaRecord>
    <Demographic>
      <PatientID>12345</PatientID>
      <DOB>1972-03-30T00:00:00</DOB>
    </Demographic>
    <Procedure>
      <Facility>LHOP </Facility>
    </Procedure>
    <AnethesiaCase>
      <AnesthesiaRecordID>1234520180201</AnesthesiaRecordID>
      <AnesthesiaStaffSet>
        <AnesthesiaStaff>
          <ProvCode>OBR</ProvCode>
        </AnesthesiaStaff>
      </AnesthesiaStaffSet>
    </AnethesiaCase>
  </AnesthesiaRecord>
  <AnesthesiaRecord>
    <Demographic>
      <PatientID>54321</PatientID>
      <DOB>2006-04-01T00:00:00</DOB>
    </Demographic>
    <Procedure>
      <Facility>LHOP </Facility>
    </Procedure>
    <AnethesiaCase>
      <AnesthesiaRecordID>5432120180215</AnesthesiaRecordID>
      <AnesthesiaStaffSet>
        <AnesthesiaStaff>
          <ProvCode>LUN</ProvCode>
        </AnesthesiaStaff>
      </AnesthesiaStaffSet>
    </AnethesiaCase>
  </AnesthesiaRecord>
  <AnesthesiaRecord>
    <Demographic>
      <PatientID>54321</PatientID>
      <DOB>2006-04-01T00:00:00</DOB>
    </Demographic>
    <Procedure>
      <Facility>LHOP </Facility>
    </Procedure>
    <AnethesiaCase>
      <AnesthesiaRecordID>5432120180215</AnesthesiaRecordID>
      <AnesthesiaStaffSet>
        <AnesthesiaStaff>
          <ProvCode>REA</ProvCode>
        </AnesthesiaStaff>
      </AnesthesiaStaffSet>
    </AnethesiaCase>
  </AnesthesiaRecord>
</AnesthesiaRecords>

输出需要像这样整合 -

<AnesthesiaRecords>
      <AnesthesiaRecord>
        <Demographic>
          <PatientID>12345</PatientID>
          <DOB>1972-03-30T00:00:00</DOB>
        </Demographic>
        <Procedure>
          <Facility>LHOP </Facility>
        </Procedure>
        <AnethesiaCase>
          <AnesthesiaRecordID>1234520180201</AnesthesiaRecordID>
          <AnesthesiaStaffSet>
            <AnesthesiaStaff>
              <ProvCode>BUS</ProvCode>
            </AnesthesiaStaff>
            <AnesthesiaStaff>
              <ProvCode>OBR</ProvCode>
            </AnesthesiaStaff>
          </AnesthesiaStaffSet>
        </AnethesiaCase>
      </AnesthesiaRecord>
     <AnesthesiaRecord>
        <Demographic>
          <PatientID>54321</PatientID>
          <DOB>2006-04-01T00:00:00</DOB>
        </Demographic>
        <Procedure>
          <Facility>LHOP </Facility>
        </Procedure>
        <AnethesiaCase>
          <AnesthesiaRecordID>5432120180215</AnesthesiaRecordID>
          <AnesthesiaStaffSet>
          <AnesthesiaStaff>
              <ProvCode>LUN</ProvCode>
            </AnesthesiaStaff>
            <AnesthesiaStaff>
              <ProvCode>REA</ProvCode>
            </AnesthesiaStaff>
          </AnesthesiaStaffSet>
      </AnethesiaCase>
      </AnesthesiaRecord>
    </AnesthesiaRecords>

Answer 1

下次提出问题时，请添加一些示例数据，最好使用DDL和DML（read about MCVE）。并尝试减少相关部分的部分。如果可能有多个：2就足够了。如果有几个相同的：1就够了。

您的XML似乎非常直接。只有一行，一些元素更深层次嵌套，但仍然是1:1。唯一的1:n元素似乎是<AnesthesiaStaff>。你自己的查询实际上非常接近。

我改变了什么：

取走INNER JOIN provcode_t并将其放在子选项（相关子查询）中。

将2018-02-05更改为20180205，因为ISO8601格式与DATETIME无法独立于文化（不过现在不是您的目标数据类型）

将AnesthesiaStaffSet放置为ROOT作为子选择，并将[*]用作创建的内部XML的列名称

尝试一下（我无法测试）

select p.acctno as [Demographic/PatientID], p.patdob as [Demographic/DOB], c.poscode as [Procedure/Facility], (select CAST(c.acctno as varchar(10)) + CONVERT(varchar(10), c.dateofservice, 112) as [AnesthesiaRecordID], (select d.provcode as [AnesthesiaStaff] from provcode_t d where c.provcode = d.provcode FOR XML PATH ('AnesthesiaStaff'),ROOT('AnesthesiaStaffSet'), TYPE ) FOR XML PATH ('AnethesiaCase'), TYPE ) AS [*] from patdemo_t p inner join charge_t c on p.acctno = c.acctno where p.acctno in (12345, 54321) and c.dateofservice in ('20180215','20180201') group by p.acctno, c.poscode, p.patdob, p.patfname, p.patlname, c.acctno, c.dateofservice FOR XML PATH ('AnesthesiaRecord'), ROOT('AnesthesiaRecords'), TYPE

如果这不能解决您的问题，请使用编辑选项为您的问题添加MCVE。
