Question

我有这样的情况：

CREATE TABLE _GoLink_Xml
    (
          RecordId INT IDENTITY(1,1) NOT NULL PRIMARY KEY,
          XmlData XML NOT NULL
    )
    GO


INSERT INTO _GoLink_Xml(XmlData)
SELECT *
FROM OPENROWSET(
   BULK 'C:\golink_0607.xml', SINGLE_BLOB)
AS ImportSource
GO

XML看起来像这样

</Main>

我的代码是这样的：

SELECT
      pref.value('(Date/text())[1]', 'date') as Date,
      pref.value('(Time/text())[1]', 'time') as Time,
      pref.value('(FromDate/text())[1]', 'date') as FromDate,
      pref.value('(ToDate/text())[1]', 'date') as ToDate,
      pref.value('(Status/text())[1]','varchar(50)') as Status

FROM  
      _GoLink_Xml 
      CROSS APPLY
         XmlData.nodes('Main/Export') AS a(pref)

我是这样的：

Date        Time            FromDate    ToDate      Status
2015-07-06  11:57:39.000000 2015-07-06  2015-07-06  NULL

如果我使用：

SELECT
      pref.value('(Date/text())[1]', 'date') as Date,
      pref.value('(Time/text())[1]', 'time') as Time,
      pref.value('(FromDate/text())[1]', 'date') as FromDate,
      pref.value('(ToDate/text())[1]', 'date') as ToDate,
      pref.value('(Status/text())[1]','varchar(50)') as Status

FROM  
      _GoLink_Xml 
CROSS APPLY
     XmlData.nodes('Main/Export') AS a(pref) 
CROSS APPLY
     XmlData.nodes('Tickets/Ticket') AS a(pref)

我一无所获。

有人知道我做错了什么吗？

Answer 1

您是否通过此代码获得了正确的结果？

SELECT 
   ExportDate = ColExport.value('(Date)[1]', 'date') ,
   ExportTime = ColExport.value('(Time)[1]', 'time'),
   ExportFromDate = ColExport.value('(FromDate)[1]', 'date'),
   ExportToDate = ColExport.value('(ToDate)[1]', 'date'),
   -- use the @Status to get the XML attribute (not element!) for "Status"
   TicketStatus = ColTicket.value('@Status','varchar(50)') 
FROM 
   _Go_Link_Xml
CROSS APPLY
   -- the nodes <Main>/<Export> have some base data
   XmlData.nodes('Main/Export') AS XT1(ColExport)
CROSS APPLY
   -- the nodes <Main>/<Tickets>/<Ticket> have ticket-related data
   XmlData.nodes('Main/Tickets/Ticket') AS XT2(ColTicket)

我得到了我期待的数据 - 即使XML中有两个<Ticket>个节点（这是我假设你想要实现的 - 正确吗？）

你的问题是：

你没有合适的XPath来到<Tickets> - 你错过了<Main>以下的事实
当你有两个单独的.nodes()时，你应该不对XML伪表和列使用相同的别名！（AS a(pref)）为每个案例使用唯一的别名

解析从xml到sql的多个不同值
