How to fetch XML node value with namespace in sql server?

Question

I have to get values of company node elements.I have tried all the method to fetch data from the node but no luck. Below is my XML.

<?xml version="1.0"?>
    <CompanyInvoice xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
      <Customer xmlns="http://t.service/CompanyServices/">
        <Company>
          <CompanyId>10001</CompanyId>
          <CoastalId>454564564564564564564564565465454546565555555</CoastalId>
          <CompanyFederalId>345345</CompanyFederalId>
          <CompanyName>Anytime Home</CompanyName>
          <CompanyAddress>Address1</CompanyAddress>
          <CompanyCity>TR</CompanyCity>
          <CompanyState>UT</CompanyState>
          <CompanyPostalCode>11</CompanyPostalCode>
          <CompanyCountry>IT</CompanyCountry>
          <CompanyTelephone>(999) 999-9999</CompanyTelephone>
        </Company>
        <CustomerId>33642</CustomerId>    
      </Customer>
      </CompanyInvoice>

TSQL Code: I have simply tried with this, but not getting any updates

Declare @DATAXML xml ='<?xml version="1.0"?>
    <CompanyInvoice xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
      <Customer xmlns="http://t.service/CompanyServices/">
        <Company>
          <CompanyId>10001</CompanyId>
          <CoastalId>454564564564564564564564565465454546565555555</CoastalId>
          <CompanyFederalId>345345</CompanyFederalId>
          <CompanyName>Anytime Home</CompanyName>
          <CompanyAddress>Address1</CompanyAddress>
          <CompanyCity>TR</CompanyCity>
          <CompanyState>UT</CompanyState>
          <CompanyPostalCode>11</CompanyPostalCode>
          <CompanyCountry>IT</CompanyCountry>
          <CompanyTelephone>(999) 999-9999</CompanyTelephone>
        </Company>
        <CustomerId>33642</CustomerId>    
      </Customer>
      </CompanyInvoice>'


;WITH XMLNAMESPACES('http://t.service/CompanyServices/' as x)
Select
a.value('x:CompanyId[1]','nvarchar(50)') as CompanyId, 
a.value('x:CoastalId[1]','nvarchar(500)') as CoastalId, 
a.value('x:CompanyName[1]','nvarchar(500)') as CompanyName
From @DATAXML.nodes('/CompanyInvoice/Customer/Company')as a (a)

You need to introduce and use namespaces in your query. See https://learn.microsoft.com/en-us/sql/relational-databases/xml/add-namespaces-to-queries-with-with-xmlnamespaces#using-with-xmlnamespaces-with-the-xml-data-type-methods — Serg, Sep 01 '17 at 07:28
But you haven't mentioned `x` namespace in the `nodes` ...nodes('CompanyInvoice/x:Customer/x:Company') ... — Serg, Sep 01 '17 at 07:50

Basically you have two options. 1.Introduce and use namespaces properly. Pay attention to namespaces scope. 2.Use a wildcard namespace (not recommended in production)

Declare @DATAXML xml = N'<?xml version="1.0"?>
    <CompanyInvoice xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
      <Customer xmlns="http://t.service/CompanyServices/">
        <Company>
          <CompanyId>10001</CompanyId>
          <CoastalId>454564564564564564564564565465454546565555555</CoastalId>
          <CompanyFederalId>345345</CompanyFederalId>
          <CompanyName>Anytime Home</CompanyName>
          <CompanyAddress>Address1</CompanyAddress>
          <CompanyCity>TR</CompanyCity>
          <CompanyState>UT</CompanyState>
          <CompanyPostalCode>11</CompanyPostalCode>
          <CompanyCountry>IT</CompanyCountry>
          <CompanyTelephone>(999) 999-9999</CompanyTelephone>
        </Company>
        <CustomerId>33642</CustomerId>    
      </Customer>
      </CompanyInvoice>';


WITH XMLNAMESPACES('http://t.service/CompanyServices/' as x)
Select
a.value('x:CompanyId[1]','nvarchar(50)') as CompanyId, 
a.value('x:CoastalId[1]','nvarchar(500)') as CoastalId, 
a.value('x:CompanyName[1]','nvarchar(500)') as CompanyName
From @DATAXML.nodes('CompanyInvoice/x:Customer/x:Company')as a (a);

-- 

select t.node.value('*:CompanyId[1]', 'int')
from @DATAXML.nodes('*:CompanyInvoice/*:Customer/*:Company') t(node);

Thanks for this, But why we don't use wild card in production — sachin, Sep 01 '17 at 09:01
Generally xml comes from another loosely coupled system and we don't want any bad stuff entering our DB. As namespaces are an essential part of the data exchange contract, we'd better strictly define them the way contract prescribes. — Serg, Sep 01 '17 at 09:14

SELECT

    CROSS APPLY
    x.item.nodes('./*') AS y(item)

SELECT
    CAST(CAST(x.item.query('data(fish)') AS varchar(30)) AS float),
    CAST(LEFT(CAST(x.item.query('data(bicycle)') AS char(25)), 10) AS smalldatetime),
    CAST(x.item.query('data(foo)') AS varchar(25))
FROM
    @foo.nodes('harrys/harry') x(item)

SELECT
    CAST(CAST(y.item.query('data(fish)') AS varchar(30)) AS float),
    CAST(LEFT(CAST(y.item.query('data(bicycle)') AS char(25)), 10) AS smalldatetime),
    CAST(y.item.query('data(foo)') AS varchar(25))
FROM
    @foo.nodes('/harrys') x(item)
    CROSS APPLY
    x.item.nodes('./harry') AS y(item)
