解析XML by OpenXML with multiple Parent nodes with multiple child nodes
Parsing XML by OpenXML with multiple Parent nodes with multiple child nodes
我有以下 XML:
<Report>
<Accounts>
<Account>
<Currency>USD</Currency>
<AccountBalance>45555</AccountBalance>
<Payments>
<PaymentData>
<PaymentCode>502</PaymentCode>
<PaymentAmount currCode="GBP">7000.00000000</PaymentAmount>
</PaymentData>
<PaymentData>
<PaymentCode>501</PaymentCode>
<PaymentAmount currCode="USD">5000.00000000</PaymentAmount>
</PaymentData>
</Payments>
</Account>
<Account>
<Currency>USD</Currency>
<AccountBalance>50000</AccountBalance>
<Payments>
<PaymentData>
<PaymentCode>501</PaymentCode>
<PaymentAmount currCode="USD">5000.00000000</PaymentAmount>
</PaymentData>
</Payments>
</Account>
</Accounts>
</Report>
我的 SQL 代码正在使用以下代码对此进行解析:
SELECT
[currCode] AS [Currency],
[AccountBalance] AS [AccountBalance],
[PaymentCode] AS [PaymentCode],
[PaymentCurrCode] AS [PaymentCurrCode],
[PaymentAmount] AS [PaymentAmount]
FROM OPENXML(@hDoc, 'Report/Accounts/Account',2)
WITH
(
[currCode] [nchar](3) 'currCode',
[AccountBalance] [decimal](18, 0) 'AccountBalance',
[PaymentCode] [nchar](10) 'Payments/PaymentData/PaymentCode',
[PaymentCurrCode] [nchar](3) 'Payments/PaymentData/PaymentAmount/@currCode',
[PaymentAmount] [decimal](18, 0) 'Payments/PaymentData/PaymentAmount'
)
我得到以下结果:
currCode | AccountBalance | PaymentCode | PaymentCurrCode | PaymentAmount
————————————————————————————————————————————————————————————————————————————————
USD | 45555 | 502 | GBP |7000.00000000
USD | 50000 | 501 | USD |5000.00000000
我正在尝试使用相同的 openXml 查询获取多个付款数据和多个帐户。 Can 如何获取具有以下结果的所有数据:
currCode | AccountBalance | PaymentCode | PaymentCurrCode | PaymentAmount
————————————————————————————————————————————————————————————————————————————————
USD | 45555 | 502 | GBP |7000.00000000
USD | 45555 | 501 | USD |5000.00000000
USD | 50000 | 501 | USD |5000.00000000
这应该适合你:

这是使用 XQuery/XPath 方法的最新和最先进的方法。结果是一样的,只是读起来更快更好:
