Question

我一直在努力解决这个问题。谷歌有助于理解“价值”，“节点”，“查询”语法，但出于某种原因，我无法弄清楚如何从我的XML中提取这些数据值。

我已经包含了一些包含查询的示例SQL（标识我想要提取的值）。我已经成功地提取了lsid，但是标签值，例如start_time由于某种原因只是空白。

非常感谢任何帮助...

这会返回您的值：

select

    lsid = @xmldata.value('(/*/@lsid)[1]', 'VARCHAR(500)')
    ,start_time = @xmldata.value('(/*:session/*:start_time)[1]', 'VARCHAR(50)')  --works
    ,end_time = null 
    ,duration = null
    ,file_transfer_count = null
    ,file_move_count = null
    ,file_delete_count = null
    ,primary_customer = null
    ,primary_rep = null
    ,public_ip = null
    ,private_ip = null
    ,hostname = null
    ,@xmldata
