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="value 8GB">
            <string>SQL Server 2000</string>

        </type>
      </tag>
    </tag>
