Parsing XML by OpenXML with multiple Parent nodes with multiple child nodes - sql

Question

I have the following 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>
My SQL Code is parsing this with the following code:
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'
)
I am getting the following result:
currCode | AccountBalance | PaymentCode | PaymentCurrCode | PaymentAmount
————————————————————————————————————————————————————————————————————————————————
USD | 45555 | 502 | GBP |7000.00000000
USD | 50000 | 501 | USD |5000.00000000
I am trying to get the multiple paymentdata and multiple account with the same openXml query. How Can is get all the data with the following result:
currCode | AccountBalance | PaymentCode | PaymentCurrCode | PaymentAmount
————————————————————————————————————————————————————————————————————————————————
USD | 45555 | 502 | GBP |7000.00000000
USD | 45555 | 501 | USD |5000.00000000
USD | 50000 | 501 | USD |5000.00000000

Answer 1

This is an up-to-date and state-of-the-art approach with XQuery/XPath methods. The result is the same, just faster and better to read:
DECLARE #XML 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>';
SELECT Payment.value('(../../Currency)[1]','nchar(3)') AS currCode
,Payment.value('(../../AccountBalance)[1]','decimal(18,0)') AS AccountBalance
,Payment.value('PaymentCode[1]','nchar(10)') AS PaymentCode
,Payment.value('PaymentAmount[1]/#currCode','nchar(3)') AS PaymentCurrCode
,Payment.value('PaymentAmount[1]','decimal(18,0)') AS PaymentCurrCode
FROM #XML.nodes('Report/Accounts/Account/Payments/PaymentData') AS One(Payment)

Answer 2

This should work for you:
DECLARE #XML 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>';
DECLARE #hDoc INT;
EXEC sp_xml_preparedocument #hDoc OUTPUT, #XML;
SELECT
[currCode] AS [Currency],
[AccountBalance] AS [AccountBalance],
[PaymentCode] AS [PaymentCode],
[PaymentCurrCode] AS [PaymentCurrCode],
[PaymentAmount] AS [PaymentAmount]
FROM OPENXML(#hDoc, 'Report/Accounts/Account/Payments/PaymentData',2)
WITH
(
[currCode] [nchar](3) '../../Currency',
[AccountBalance] [decimal](18, 0) '../../AccountBalance',
[PaymentCode] [nchar](10) 'PaymentCode',
[PaymentCurrCode] [nchar](3) 'PaymentAmount/#currCode',
[PaymentAmount] [decimal](18, 0) 'PaymentAmount'
)
EXEC sp_xml_removedocument #hDoc;
