問(wèn)題描述

希望你們一切順利.

我需要將 XML 源從網(wǎng)站導(dǎo)入到我的 SQL Server 數(shù)據(jù)庫(kù).我對(duì) XML 不太了解.

I need to import an XML-feed from a website to my SQL Server database. I don't know much about XML.

Feed 結(jié)構(gòu)有點(diǎn)復(fù)雜.這是該文件的示例:

The feed structure is an bit complex. Here is the sample of that file:

<line_feed>
<FeedTime>1279519582927</FeedTime>
<lastContest>4103839</lastContest>
<lastGame>58629754</lastGame>
<events>
<event>
    <event_datetimeGMT>2010-07-19 21:30</event_datetimeGMT>
    <gamenumber>174087393</gamenumber>
    <sporttype>Tennis</sporttype>
    <league>abc</league>
    <participants>
        <participant>
            <participant_name>R. Ram</participant_name>
            <contestantnum>4303</contestantnum>
            <rotnum>4303</rotnum>
            <visiting_home_draw>Visiting</visiting_home_draw>
        </participant>
        <participant>
            <participant_name>K. Beck</participant_name>
            <contestantnum>4304</contestantnum>
            <rotnum>4304</rotnum>
            <visiting_home_draw>Home</visiting_home_draw>
        </participant>
    </participants>
    <periods>
        <period>

            </moneyline>
        </period>
        <period>
            <period_number>0</period_number>

            </moneyline>
        </period>
    </periods>
</event>
</events>
</line_feed>

能否請(qǐng)您幫幫我，我該如何將數(shù)據(jù)從該提要加載到 SQL Server.

Can you please help me out, how can I approach to load the data from that feed to SQL Server.

另請(qǐng)?jiān)儐?wèn)我是否需要了解此場(chǎng)景的任何其他詳細(xì)信息.等待您的友好回復(fù).

Please also ask me if any other details needed to understand this scenario. Awaiting your kind response.

謝謝，普拉桑特

推薦答案

如果您的 XML 格式良好，您可以將其存儲(chǔ)在 xml 類(lèi)型變量中.然后你可以使用 XPath 從中讀取字段:

If your XML is wel-formed, you can store it in an xml type variable. Then you can use XPath to read fields from it:

declare @xml xml
set @xml = '
<line_feed>
<PinnacleFeedTime>1279519582927</PinnacleFeedTime>
...
'

select @xml.value('(line_feed/events/event/sporttype)[1]', 'VARCHAR(8000)')

這將打印Tennis.
