SQL Convert XML to Table

•  将xml nodes 属性中的值 转为table 形式

  declare @xml2 xml

  set @xml2 = '<CMADatas>

  <CMAData CmaName="EventCfgItem" CmaValue="sap-abc1a01" />

  <CMAData CmaName="EventNode" CmaValue="" />

  <CMAData CmaName="EventSource" CmaValue="" />

  <CMAData CmaName="EventType" CmaValue="" />

  <CMAData CmaName="EventTypeInstance" CmaValue="" />

</CMADatas>'

 select S.value('@CmaName', 'varchar(36)') as CmaName

          , S.value('@CmaValue', 'varchar(36)') as CmaName

 from @xml2.nodes('/CMADatas/CMAData') as T(S)

 

• 将 xml tag标签的中值 转为 table 格式

DECLARE @xml xml='<mssql version="10.50.4000" name="Microsoft SQL Server Developer Edition (64-bit)">

  <type name="Windows 7 Main Server">

    <tag KeyValue="enabled">

      <boolean>true</boolean>

    </tag>

    <tag KeyValue="disabled">

          </tag>

          <tag KeyValue="value 8GB">

            <string>SQL Server 2000</string>

          </tag>

        </type>

      </tag>

      <tag method="Read">

            <string>SQL Server 2005 SP3</string>

          </tag>

        </type>

      </tag>

    </tag>

  </type>
