我的问题是，当我执行我的存储过程时，XML数据不会保存在我的表中。我没有收到任何错误代码：（（

答案 0 :(得分：0)

调试SELECT语句时，最后两个CROSS APPLY语句显然不会返回任何数据：

CROSS APPLY 
    TEMPTABLE.quakedetails.nodes('origin/description/text') AS plac(placee)
CROSS APPLY 
    TEMPTABLE.quakedetails.nodes('origin/description/type') AS typ(typo)

请检查您的XML - 不知何故，origin/description路径似乎不存在。

如果您检查XML，则会发现<description>节点直接位于<event>节点下 - 而不是<origin>下 - 请使用此命令：

CROSS APPLY 
    TEMPTABLE.quakedetails.nodes('description/text') AS plac(placee)
CROSS APPLY 
    TEMPTABLE.quakedetails.nodes('description/type') AS typ(typo)

然后您的查询应该有效。

更新：您可以通过对CROSS APPLY个函数进行尽可能多的.nodes()调用来优化您的查询 - 仅限于<origin>个节点，然后使用XPath表达式获取该节点内的各个部分 - 尝试此查询：

; WITH XMLNAMESPACES ('http://quakeml.org/xmlns/quakeml/1.2' as q,
                      default 'http://quakeml.org/xmlns/bed/1.2')
 SELECT
     Times = XOrigin.value('(time/value)[1]', 'varchar(100)'),
     Latitude = XOrigin.value('(latitude/value)[1]', 'numeric(18,6)'),
     Longitude = XOrigin.value('(longitude/value)[1]', 'numeric(18,6)'),
     Depth = XOrigin.value('(depth/value)[1]', 'numeric(18,6)'),
     Magnitude = XEvent.value('(magnitude/value)[1]', 'numeric(18,6)'),
     Mag_Type = XEvent.value('(magnitude/type/value)[1]', 'varchar(100)'),
     Place = XEvent.value('(description/text)[1]', 'varchar(100)'),
     [Type] = XEvent.value('(description/type)[1]', 'varchar(100)')
 FROM
        @xml.nodes('/q:quakeml/eventParameters/event') as XT1(XEvent)
 CROSS APPLY
        XEvent.nodes('origin') AS XT2(XOrigin)

这只是SELECT - 运行得更快吗？
