Retrieving xml attribute using Xquery - sql-server

Question

I am using the below query to select the values of XML from attributes ad elements of the XML file but I am not able to read the seq, id, reported dated attributes from XML page
so any one please suggest How to get values of attributes using this Query.
select a_node.value('(./text())[1]', 'var char(50)') AS c_val,
c1_node.value('(./text())[1]', 'var char(50)') AS c_val 2,
ca_node.value('(./text())[1]', 'var char(50)') AS c_val3,
d_node.value('(./text())[1]', 'var char(50)') ,
e_node.value('(./text())[1]', 'varchar(50)') ,
f_node.value('(./text())[1]', 'var char(50)')
FROM #xmlData.nodes('/Reports/x:InquiryResponse/x:ReportData/x:AccountDetails/x:Account') AS b(b_node)
outer APPLY b.b_node.nodes('./x:primarykey') AS pK_InquiryResponse (a_node)
outer APPLY b.b_node.nodes('./x:seq') AS CustomerCode (c1_node)
outer APPLY b.b_node.nodes('./x:id') AS amount (ca_node)
outer APPLY b.b_node.nodes('./x:ReportedDate') AS CustRefField (d_node)
outer APPLY b.b_node.nodes('./x:AccountNumber') AS ReportOrderNO (e_node)
outer apply b.b_node.nodes('./x:CurrentBalance') as additional_id (f_node);
Edit: Xml Snippets Provided in Comments
<sch:Account seq="2" id="345778174" ReportedDate="2014-01-01">
<sch:AccountNumber>TSTC1595</sch:AccountNumber>
<sch:CurrentBalance>0</sch:CurrentBalance>
<sch:Institution>Muthoot Fincorp Limited</sch:Institution>
<sch:PastDueAmount>0</sch:PastDueAmount>
<sch:DisbursedAmount>12000</sch:DisbursedAmount>
<sch:LoanCategory>JOG Group</sch:LoanCategory>
</sch:Account>
<sch:Account seq="2" id="345778174" ReportedDate="2014-01-01">
<sch:BranchIDMFI>THRISSUR ROAD</sch:BranchIDMFI>
<sch:KendraIDMFI>COSTCO/RECENT-107</sch:KendraIDMFI>
</sch:Account>

Parsing XQuery with an Xml Loose #Variable
Assuming an Xml document similar to this (viz with all the attributes on one element):
DECLARE #xmlData XML =
N'<Reports xmlns:x="http://foo">
<x:InquiryResponse>
<x:ReportData>
<x:AccountDetails>
<x:Account x:primarykey="pk" x:seq="sq" x:id="id"
x:ReportedDate="2014-01-01T00:00:00" />
</x:AccountDetails>
</x:ReportData>
</x:InquiryResponse>
</Reports>';
You can scrape the attributes out as follows:
WITH XMLNAMESPACES('http://foo' AS x)
select
Nodes.node.value('(#x:primarykey)[1]', 'varchar(50)') AS c_val,
Nodes.node.value('(#x:seq)[1]', 'varchar(50)') AS c_val2,
Nodes.node.value('(#x:id)[1]', 'varchar(50)') AS c_val3,
Nodes.node.value('(#x:ReportedDate)[1]', 'DATETIME') as someDateTime
FROM
#xmlData.nodes('/Reports/x:InquiryResponse/x:ReportData/x:AccountDetails/x:Account')
AS Nodes(node);
Attributes don't need text() as they are automatically strings
It is fairly unusual to have attributes in a namespace - drop the xmlns alias prefix if they aren't.

Edit - Parsing Xml Column
Namespace dropped from the attributes
-Assumed that you have the data in a table, not a variable, hence the APPLY requirement. Note that OUTER APPLY will return nulls, e.g. useful only if you have rows with
empty Xml or missing Xml Elements. CROSS APPLY is the norm (viz
applying the xpath to each row selected on the LHS table)
Elements are accessed similar to attributes, just without #
WITH XMLNAMESPACES('http://foo' AS x)
select
Nodes.node.value('(#seq)[1]', 'varchar(50)') AS c_val2,
Nodes.node.value('(#id)[1]', 'varchar(50)') AS c_val3,
Nodes.node.value('(#ReportedDate)[1]', 'DATETIME') as someDateTime,
Nodes.node.value('(x:AccountNumber)[1]', 'VARCHAR(50)') as accountNumber
FROM
MyXmlData z
CROSS APPLY
z.XmlColumn.nodes('/Reports/x:InquiryResponse/x:ReportData/x:AccountDetails/x:Account')
AS Nodes(node);

Edit Xml File off Disk
Here's the same thing for an xml file read from disk. Note that once you have the data in an XML variable (#MyXmlData) that you don't need to CROSS APPLY to anything - just supply xpath to select the appropriate node, and then scrape out the elements and attributes.
DECLARE #MyXmlData XML;
SET #MyXmlData =
( SELECT * FROM OPENROWSET ( BULK N'c:\temp\file3098.xml', SINGLE_CLOB ) AS MyXmlData );
-- Assuming all on the one element, no need for all the applies
-- attributes don't have a text axis (they are automatically strings
WITH XMLNAMESPACES('http://foo' AS x)
select
Nodes.node.value('(#seq)[1]', 'varchar(50)') AS c_val2,
Nodes.node.value('(#id)[1]', 'varchar(50)') AS c_val3,
Nodes.node.value('(#ReportedDate)[1]', 'DATETIME') as someDateTime,
Nodes.node.value('(x:AccountNumber)[1]', 'VARCHAR(50)') as accountNumber
FROM
#MyXmlData.nodes('/Reports/x:InquiryResponse/x:ReportData/x:AccountDetails/x:Account')
AS Nodes(node);
