Open XML select values with XML name space - sql-server

Question

I am trying to select some values using open xml in sql server 2012. This works when I don't have any xml name space. But whenever the below prefix get added with root element, I am not able to select values. Any suggestion how I can select values with xmlns:
xmlns="somenamspace/2006-10-31" order-no="00000001"
USE grails
GO
DECLARE #XML AS XML, #hDoc AS INT, #SQL NVARCHAR (MAX), #rootxmlns varchar(100)
SELECT #XML = N'<order xmlns="somenamspace/2006-10-31" order-no="00000001">
<order-date>2017-07-24T20:48:57.000Z</order-date>
<original-order-no>00000001</original-order-no>
<customer>
<customer-name>abcd abcd</customer-name>
<customer-email>jjj#gmail.com</customer-email>
</customer>
<current-order-no>00000001</current-order-no>
<payments>
<payment>
<credit-card>
<card-type>VISA</card-type>
<card-number>XXXX-XXXX-XXXX-1111</card-number>
<card-holder>abcd</card-holder>
<expiration-month>1</expiration-month>
<expiration-year>2021</expiration-year>
</credit-card>
<amount>325.48</amount>
</payment>
</payments>
</order>';
SET #rootxmlns = '<root xmlns:ns1="somenamspace/2006-10-31"/>'
EXEC sp_xml_preparedocument #hDoc OUTPUT, #XML, #rootxmlns
SELECT orderNo
FROM OPENXML(#hDoc, 'ns1:order',2)
WITH
(
orderNo [varchar](50) 'original-order-no'
)
SELECT *
FROM OPENXML(#hDoc, 'ns1:order/customer',2)
WITH
(
customerName [varchar](50) 'customer-name',
customerEmail [varchar](100) 'customer-email'
)
SELECT cardType, cardNumber, cardHolder
FROM OPENXML(#hDoc, '/order/payments/payment/credit-card',2)
WITH
(
cardType [varchar](50) 'card-type',
cardNumber [varchar](100) 'card-number',
cardHolder [varchar](100) 'card-holder'
)
EXEC sp_xml_removedocument #hDoc
GO

Great, that you've found an answer yourself, but this can be solved better.
FROM OPENXML with the corresponding SPs to open and to remove a document is outdated and should not be used any more. Rather use the methods, the native XML type provides:
The following will give you at least some templates how to access the values within your XML:
DECLARE #XML AS XML=
N'<order xmlns="somenamspace/2006-10-31" order-no="00000001">
<order-date>2017-07-24T20:48:57.000Z</order-date>
<original-order-no>00000001</original-order-no>
<customer>
<customer-name>abcd abcd</customer-name>
<customer-email>jjj#gmail.com</customer-email>
</customer>
<current-order-no>00000001</current-order-no>
<payments>
<payment>
<credit-card>
<card-type>VISA</card-type>
<card-number>XXXX-XXXX-XXXX-1111</card-number>
<card-holder>abcd</card-holder>
<expiration-month>1</expiration-month>
<expiration-year>2021</expiration-year>
</credit-card>
<amount>325.48</amount>
</payment>
</payments>
</order>';
--The query
WITH XMLNAMESPACES(DEFAULT N'somenamspace/2006-10-31')
SELECT #xml.value(N'(/order/#order-no)[1]',N'int') AS OrderNumber
,#xml.value(N'(/order/order-date/text())[1]',N'datetime') AS OrderDate
,#xml.value(N'(/order/customer/customer-name/text())[1]',N'nvarchar(max)') AS CustomerName
,p.value(N'local-name(.)',N'nvarchar(max)') AS PaymentType
,p.value(N'(card-type/text())[1]','nvarchar(max)') AS CardType
,p.value(N'(../amount/text())[1]','decimal(10,4)') AS Amount
FROM #xml.nodes(N'/order/payments/payment/*[local-name()!="amount"]') AS A(p)
The result
Nr OrderDate CustomerName PaymentType CardType Amount
1 2017-07-24 20:48:57.000 abcd abcd credit-card VISA 325.4800
Explanation
Some data is taken directly via XPath out of #xml. The statement FROM #xml.nodes() will create a derived table of <payments><payment> nodes (as the wording suggests a 1:n relationship. The <amount> node is handled explicitly, the other node within <payment> is taken as payment details.

Got it,need to add name space in property level as well:
SET #rootxmlns = '<root xmlns:ns1="http://www.demandware.com/xml/impex/order/2006-10-31"/>'
EXEC sp_xml_preparedocument #hDoc OUTPUT, #XML, #rootxmlns
SELECT orderNo
FROM OPENXML(#hDoc, 'ns1:order',2)
WITH
(
orderNo [varchar](50) 'ns1:original-order-no'
)
SELECT *
FROM OPENXML(#hDoc, 'ns1:order/ns1:customer',2)
WITH
(
customerName [varchar](50) 'ns1:customer-name',
customerEmail [varchar](100) 'ns1:customer-email'
)
SELECT cardType, cardNumber, cardHolder
FROM OPENXML(#hDoc, 'ns1:order/ns1:payments/ns1:payment/ns1:credit-card',2)
WITH
(
cardType [varchar](50) 'ns1:card-type',
cardNumber [varchar](100) 'ns1:card-number',
cardHolder [varchar](100) 'ns1:card-holder'
)
EXEC sp_xml_removedocument #hDoc
GO
