使用SQL进行XML解析

Question

如何获取此xml中的所有值。我已经尝试了一切，但我无法使其工作。 任何人都可以给我快速回答？它应该至少返回行。

DECLARE @x XML = 
    '<Events> 
    <Event DateTimeGMT="25/10/2013 18:45:00" Branch="Soccer" Sport="Soccer" BranchID="1" League="England - Championship" LeagueID="10099" ID="5693075" IsOption="0" EventType="0" MEID="2673883"> 
    <Participants> 
     <Participant1 Name="Middlesbrough" Home_Visiting="Home" /> 
     <Participant2 Name="Doncaster" Home_Visiting="Visiting" /> 
    </Participants> 
    <MoneyLine Home="1.69" Draw="3.7" Away="5" /> 
    <Spread Home_Odds="1.885" Home_Points="-0.75" Away_Points="0.75" Away_Odds="1.962" /> 
    <Total Points="2.75" Over="2.06" Under="1.763" /> 
    </Event> 
    <Event DateTimeGMT="25/10/2013 18:45:00" Branch="Soccer" Sport="Soccer" BranchID="1" League="England - Championship" LeagueID="10099" ID="5693993" IsOption="1" EventType="200" MEID="2673883"> 
    <Participants> 
     <Participant1 Name="Middlesbrough" Home_Visiting="Home" /> 
     <Participant2 Name="Doncaster" Home_Visiting="Visiting" /> 
    </Participants> 
    <Total Points="4.5" Over="5.75" Under="1.125" /> 
    </Event> 
    <Event DateTimeGMT="25/10/2013 18:45:00" Branch="Soccer" BranchID="1" League="England - Championship" LeagueID="10099" QAID="4423106" EventType="38" EventName="Middlesbrough vs Doncaster"> 
    <Participants> 
     <Participant Name="Odd"> 
     <Odds TypeName="Odd/Even" OddsValue="1.909" /> 
     </Participant> 
     <Participant Name="Even"> 
     <Odds TypeName="Odd/Even" OddsValue="1.8" /> 
     </Participant> 
     . 
     . 
     . 
     <Participant Name="0:0"> 
     <Odds TypeName="Exact" OddsValue="1.8" /> 
     </Participant> 
    </Participants> 
    </Event> 
</Events>' 

DECLARE @iDoc INT 
EXECUTE sp_xml_preparedocument @iDoc OUTPUT, @x 

SELECT * 
FROM OPENXML(@iDoc,'/Events/Event/Participants') 
WITH (
ID int '../@ID', 
DateTimeGMT [varchar](100) '../@DateTimeGMT', 
Branch [varchar](100) '../@Branch', 
Sport [varchar](100) '../@Sport', 
BranchID int '../@BranchID', 
League [varchar](100) '../@League', 
LeagueID int '../@LeagueID', 
IsOption int '../@IsOption', 
EventType int '../@EventType', 
MEID int '../@MEID', 
QAID int '../@QAID', 
EventName [varchar](500) '../@EventName', 
Home [varchar](100) '..//Participant1/@Name', 
Away [varchar](100) '..//Participant2/@Name', 
[1] [varchar](5) '..//MoneyLine/@Home', 
[X] [varchar](5) '..//MoneyLine/@Draw', 
[2] [varchar](5) '..//MoneyLine/@Away', 
Spread_Home_Points float '..//Spread/@Home_Points', 
Spread_Home_Odds float '..//Spread/@Home_Odds', 
Spread_Away_Points float '..//Spread/@Away_Points', 
Spread_Away_Odds float '..//Spread/@Away_Odds', 
Total_Points float '..//Total/@Points', 
Lart float '..//Total/@Over', 
Posht float '..//Total/@Under', 
Rubrika varchar(100) 'Participant/@Name', 
Koefic varchar(100) 'Participant/Odds/@OddsValue' 
     ) 

这并不读取该节点的所有值

Rubrika varchar(100) 'Participant/@Name', 
    Koefic varchar(100) 'Participant/Odds/@OddsValue' 

它应该返回更多的行

如果我知道你需要什么，这里有你想要的查询：

select 
    T.C.value('@DateTimeGMT', 'varchar(100)') as DateTimeGMT, 
    T.C.value('@Branch', 'varchar(100)') as Branch, 
    T.C.value('@BranchID', 'int') as BranchID, 
    T.C.value('@League', 'varchar(100)') as League, 
    T.C.value('@LeagueID', 'int') as LeagueID, 
    T.C.value('@IsOption', 'int') as IsOption, 
    T.C.value('@EventType', 'int') as EventType, 
    T.C.value('@MEID', 'int') as MEID, 
    T.C.value('@QAID', 'int') as QAID, 
    T.C.value('@EventName', 'varchar(500)') as EventName, 
    T.C.value('(Participants/Participant1)[1]/@Name', 'varchar(100)') as Home, 
    T.C.value('(Participants/Participant2)[1]/@Name', 'varchar(100)') as Away, 
    T.C.value('(MoneyLine)[1]/@Home', 'varchar(5)') as [1], 
    T.C.value('(MoneyLine)[1]/@Draw', 'varchar(5)') as [X], 
    T.C.value('(MoneyLine)[1]/@Away', 'varchar(5)') as [2], 
    T.C.value('(Spread)[1]/@Home_Points', 'float') as Spread_Home_Points, 
    T.C.value('(Spread)[1]/@Home_Odds', 'float') as Spread_Home_Odds, 
    T.C.value('(Spread)[1]/@Away_Points', 'float') as Spread_Away_Points, 
    T.C.value('(Spread)[1]/@Away_Odds', 'float') as Spread_Away_Odds, 
    T.C.value('(Spread)[1]/@Away_Odds', 'float') as Spread_Away_Odds, 
    T.C.value('(Total)[1]/@Points', 'float') as Total_Points, 
    T.C.value('(Total)[1]/@Over', 'float') as Lart, 
    T.C.value('(Total)[1]/@Under', 'float') as Posht, 
    P.C.value('@Name', 'varchar(100)') as Rubrika, 
    P.C.value('(Odds)[1]/@OddsValue', 'varchar(100)') as Koefic 
from @x.nodes('Events/Event') as T(C) 
    outer apply T.C.nodes('Participants/Participant') as P(C) 

请注意，首先解析Events/Event，然后为每个发现的Participants/Participant重复行。
