如何在sql server中用命名空間獲取XML節點值？

我必須得到公司節點元素的值。我嘗試了所有的方法從節點獲取數據，但沒有運氣。以下是我的XML。如何在sql server中用命名空間獲取XML節點值？

<?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代碼：我只是嘗試了這一點，但沒有得到任何更新

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)

您需要在查詢中引入和使用名稱空間。請參閱https://docs.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

@Serg，我介紹命名空間，但沒有運氣 – sachin

基本上你有兩種選擇。 1.正確引入和使用名稱空間。注意名稱空間的作用域。 2.使用通配符命名空間（在生產中不推薦）

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);

感謝此，但爲什麼我們在生產中不使用通配符 – sachin

通常，xml來自另一個鬆散耦合的系統，我們不希望任何不良內容進入我們的數據庫。由於名稱空間是數據交換合同的重要組成部分，我們最好嚴格按合同規定的方式定義它們。 – Serg

試試這個這只是和其他例如

感謝您的回覆，但這並不能幫助我實現我的結果。我已經添加了我的tsql代碼。嘗試獲取這些值 – sachin
