ADO不支持XML在存储过程

Question

当试图从C在SQL服务器上执行存储过程++我得到CE = {DB_E_ERRORSINCOMMAND}

C++代码是

pCom->Execute(NULL,NULL,adCmdStoredProc); 

从命令对象执行..

存储过程是这样的

create PROCEDURE [dbo].[InsertTicketDetails] 
AS 
BEGIN 
DECLARE @inputXml XML; 
SET NOCOUNT ON 
set @inputXml = '<Record><studentid>143</studentid></Record>'; 

INSERT INTO dbo.sample (studentid) 
    SELECT 
     @inputXml.value('studentid[1]', 'int') AS studentid   
    FROM @inputXml.nodes('/Record') a(y) 
END 

这里inserstion做w^ith xml，如果没有xml的插入工作正常。我认为它与XML的问题，或者我们不能从C++访问SQL Server的XML功能？

该错误不在ADO中，因为它返回了一个NULL的SQL。我怀疑dbo.sample（studentid）不允许有空值。

变化INSERT语句：

INSERT INTO dbo.sample (studentid) 
SELECT 
    @inputXml.value('(/Record/studentid)[1]', 'int') AS studentid   

或

INSERT INTO dbo.sample (studentid) 
SELECT 
    @inputXml.value('(//studentid)[1]', 'int') AS studentid   
FROM @inputXml.nodes('/Record') a(y)
