在 SQL Server 2017 中导入 xml 数据

Question

我有这样的 XML 数据：

<?xml version="1.0" ?>
<SettlementFile>
    <Transaction>
        <Identifier>
            <StationID>049215901 </StationID>
            <TransactionTimestamp>2021-04-01T10:39:32</TransactionTimestamp>
        </Identifier>
        <TerminalInfo>
            <TerminalID>21590151</TerminalID>
            <TerminalType>2</TerminalType>
        </TerminalInfo>
        <TransactionInfo>
            <TransactionType>0</TransactionType>
            <TransactionAmount>3.74</TransactionAmount>
            <CurrencyCode>978</CurrencyCode>
            <CustomerInput>
                <Mileage>0</Mileage>
            </CustomerInput>
            <TicketNumber>213510037</TicketNumber>
            <AuthorisationType>1</AuthorisationType>
        </TransactionInfo>
    </Transaction>
</SettlementFile>

我的 SQL Server 表结构：

CREATE TABLE dbo.Import_Oase 
(
    StationID            varchar(50) NULL,
    TransactionTimestamp datetime    NULL,
    TicketNumber         int         NULL,
    Mileage              varchar(50) NULL
) ON PRIMARY

我正在尝试使用这个SELECT 查询：

SELECT 
    MY_XML.Details.query('StationID')           .value('.', 'VARCHAR(50)'),
    MY_XML.Details.query('TransactionTimestamp').value('.', 'Datetime'),
    MY_XML.Details.query('TicketNumber')        .value('.', 'Integer'),
    MY_XML.Details.query('Mileage')             .value('.', 'VARCHAR(50)')
FROM
    (SELECT
         CAST(MY_XML AS XML)
     FROM
         OPENROWSET(BULK '\\EO-TEST\SQL-Daten\Temp\MY_XML.xml', SINGLE_BLOB) AS T(MY_XML)
    ) AS T(MY_XML)
CROSS APPLY 
    MY_XML.nodes('SettlementFile/Transaction/Identifier, SettlementFile/Transaction/TransactionInfo, SettlementFile/Transaction/TransactionInfo/CustomerInput') AS MY_XML (Details);

我需要在一行中获得结果，因为它全部用于 1 笔交易。但它在 SQL 的三个不同的行中。

请尝试以下解决方案。

当您对结果感到满意时，只需取消注释 INSERT INTO 行。

SQL

WITH rs (xmlData) AS
(
   SELECT TRY_CAST(BulkColumn AS XML) 
   FROM OPENROWSET(BULK N'e:\Temp\ daryosmitan.xml', SINGLE_BLOB) AS x
)
-- INSERT INTO dbo.Import_Oase (StationID, TransactionTimestamp, TicketNumber, Mileage)
SELECT c.value('(Identifier/StationID/text())[1]', 'VARCHAR(50)') AS StationID
    , c.value('(Identifier/TransactionTimestamp/text())[1]', 'DATETIME') AS TransactionTimestamp
    , c.value('(TransactionInfo/TicketNumber/text())[1]', 'VARCHAR(50)') AS TicketNumber
    , c.value('(TransactionInfo/CustomerInput/Mileage/text())[1]', 'INT') AS Mileage
FROM rs 
   CROSS APPLY xmlData.nodes('/SettlementFile/Transaction') AS t(c);
