取从XML在SQL存储过程

值我试图从一个XML存储过程如下取从XML在SQL存储过程

 USE [ION] 
    GO 
    SET ANSI_NULLS ON 
    GO 
    SET QUOTED_IDENTIFIER ON 
    GO 
    ALTER PROCEDURE [dbo].[AddToCustomer] 
     (@id VARCHAR(20)) 
    AS 
    BEGIN 
     DECLARE @xx xml 
     DECLARE @custname varchar(8000) 
     DECLARE @fid varchar(20) 
     SET NOCOUNT ON; 

     SELECT @fid=[C_ID], @xx=cast([C_XML] as xml) FROM [ION].[dbo].[COR_INBOX_ENTRY] WHERE [C_WAS_PROCESSED]=0 and [C_ID][email protected] 

     if(@@ROWCOUNT!=0) 
     BEGIN 

      SELECT @xx.value('(/SyncMESCustomer/ApplicationArea/Sender/ConfirmationCode)[1]', 'varchar(100)') 
     END 

    END

我敢肯定的是，可变@xx装有XML获取的元素。我需要选择'/ SyncMESCustomer/ApplicationArea/Sender/ConfirmationCode'的值，但它返回NULL。

示例XML如下：提前

<SyncMESCustomer xmlns="http://schema.infor.com/InforOAGIS/2" xmlns:xs="http://www.w3.org/2001/XMLSchema" languageCode="GB" releaseID="9.2" systemEnvironmentCode="Production" versionID="2.9.1"> 
    <ApplicationArea> 
     <Sender> 
      <LogicalID schemeVersionID="15.4.0.0">lid://infor.m3be.ipc_mec_dev</LogicalID> 
      <ComponentID schemeVersionID="MCP2-1514-02">M3BE</ComponentID> 
      <ConfirmationCode>OnError</ConfirmationCode> 
     </Sender> 
     <CreationDateTime>2017-06-09T13:41:36.996Z</CreationDateTime> 
     <BODID>5cfa6949-11ef-41dc-a380-4cc79f2687cc</BODID> 
    </ApplicationArea> 
    <DataArea> 
     <Sync> 
      <TenantID>TEST</TenantID> 
      <AccountingEntityID>1_001</AccountingEntityID> 
      <ActionCriteria> 
       <ActionExpression actionCode="Replace" /> 
      </ActionCriteria> 
     </Sync> 
     <MESCustomer> 
      <CUSTOMER_NO>TEST6</CUSTOMER_NO> 
      <ipc_CSS_CUST_CUST_NAME> 
       <CUSTOMER_NO>TEST6</CUSTOMER_NO> 
       <CUST_NAME>Hawaii Inc_MES</CUST_NAME> 
       <STATUS_DATE>20170609</STATUS_DATE> 
       <STATUS_WORD>20</STATUS_WORD> 
      </ipc_CSS_CUST_CUST_NAME> 
      <STATUS_WORD>20</STATUS_WORD> 
     </MESCustomer> 
    </DataArea> 
</SyncMESCustomer>

感谢。

;WITH XMLNAMESPACES(DEFAULT 'http://schema.infor.com/InforOAGIS/2','http://www.w3.org/2001/XMLSchema' as ns0) 
Select @XML.value('SyncMESCustomer[1]/ApplicationArea[1]/Sender[1]/ConfirmationCode[1]','varchar(100)')

Woww ..多谢@约翰。有用。你能帮我理解XMLNAMESPACES的作用吗？ –

老实说，这是因为没有其他命名空间的默认名称空间***或***别名...如果添加一个别名，它的工作原理就好了。 – Codexer

@NikhilDominic看起来像链接被删除https://msdn.microsoft.com/en-us/library/aa468565.aspx ... –

这对我的作品......可以添加另一个别名命名空间...

<SyncMESCustomer xmlns:xz="http://schema.infor.com/InforOAGIS/2" xmlns:xs="http://www.w3.org/2001/XMLSchema" languageCode="GB" releaseID="9.2" systemEnvironmentCode="Production" versionID="2.9.1" 

DECLARE @xx XML 

SET @xx = '<SyncMESCustomer> 
    <ApplicationArea> 
     <Sender> 
      <LogicalID schemeVersionID="15.4.0.0">lid://infor.m3be.ipc_mec_dev</LogicalID> 
      <ComponentID schemeVersionID="MCP2-1514-02">M3BE</ComponentID> 
      <ConfirmationCode>OnError</ConfirmationCode> 
     </Sender> 
     <CreationDateTime>2017-06-09T13:41:36.996Z</CreationDateTime> 
     <BODID>5cfa6949-11ef-41dc-a380-4cc79f2687cc</BODID> 
    </ApplicationArea> 
    <DataArea> 
     <Sync> 
      <TenantID>TEST</TenantID> 
      <AccountingEntityID>1_001</AccountingEntityID> 
      <ActionCriteria> 
       <ActionExpression actionCode="Replace" /> 
      </ActionCriteria> 
     </Sync> 
     <MESCustomer> 
      <CUSTOMER_NO>TEST6</CUSTOMER_NO> 
      <ipc_CSS_CUST_CUST_NAME> 
       <CUSTOMER_NO>TEST6</CUSTOMER_NO> 
       <CUST_NAME>Hawaii Inc_MES</CUST_NAME> 
       <STATUS_DATE>20170609</STATUS_DATE> 
       <STATUS_WORD>20</STATUS_WORD> 
      </ipc_CSS_CUST_CUST_NAME> 
      <STATUS_WORD>20</STATUS_WORD> 
     </MESCustomer> 
    </DataArea> 
</SyncMESCustomer>' 

SELECT 
    xmlData.A.value('./ConfirmationCode[1]', 'varchar(100)') 
FROM @xx.nodes('/SyncMESCustomer/ApplicationArea/Sender') xmlData(A);
